Explosion-proof electric ball valve overview: The electric explosion-proof ball valve is mainly composed of an explosion-proof actuator and a ball valve. It is an electric explosion-proof valve used in flammable and explosive conditions. The electrical components on the explosion-proof electric ball valve are required to be fire-proof and anti-static, and all meet the explosion-proof standards. The explosion-proof grade is ExdIIBT4 (CT6), and the protection grade is IP87. The electric explosion-proof ball valve can control the valve switch by inputting the relevant power signal, and can control the operation of the ball valve by inputting the 4-20mA signal and 220/power supply for proportional adjustment, so as to achieve the automatic control of the medium flow, pressure, temperature and other parameters in the pipeline. Applied to explosion-proof occasions such as natural gas, sewage, gas, coal mine, chemical industry, etc. EXDIICT4 grade explosion-proof electric ball valve Explosion-proof electric ball valve features: Explosion-proof Shendong modified valve means that the curved heat actuator of the ball valve h meets the explosion-proof standard. It is used in places requiring explosion-proof, such as liquid or gas (inflammable and explosive places in the chemical industry, used to open and close the valve. Or section, explosion-proof valves can be divided into intrinsically safe type and explosion-proof type. The intrinsically safe type uses a DC motor, and the explosion-proof type uses an AC motor. control, and can also be operated on site. Electric explosion-proof ball valve standard specification: 1.

Sudhanafluid pneumatic valve series: butterfly valve The butterfly plate of the butterfly valve is installed in the diameter direction of the pipe. In the cylindrical channel of the butterfly valve body, the disc shaped butterfly plate rotates around the axis with a rotation angle of 0 �°~90 �°. When the rotation angle reaches 90 �°, the valve is fully open. The butterfly valve is simple in structure, small in volume and light in weight, and only consists of a few parts. Moreover, the valve can be quickly opened and closed only by rotating 90 �°, which is simple to operate. At the same time, the valve has good fluid control characteristics. When the butterfly valve is in the fully open position, the thickness of the butterfly plate is the resistance when the medium flows through the valve body, so the pressure drop generated by the valve is very small, so it has good flow control characteristics. The butterfly valve has two sealing types: elastic seal and metal seal. For elastic sealing valves, the sealing ring can be embedded on the valve body or attached to the periphery of the butterfly plate. The valve with metal seal is generally longer than the valve with elastic seal, but it is difficult to achieve complete sealing. The metal seal can adapt to higher working temperature, while the elastic seal has the defect of being limited by temperature. If the butterfly valve is required to be used for flow control, the main thing is to correctly select the size and type of the valve. The structure principle of butterfly valve is especially suitable for making large diameter valves. Butterfly valves are not only widely used in petroleum, gas, chemical industry, water treatment and other general industries, but also used in the cooling water system of thermal power plants. There are two kinds of butterfly valves commonly used: wafer type butterfly valve and flange type butterfly valve. Wafer type butterfly valve uses stud bolts to connect the valve between two pipe flanges. Flange type butterfly valve has flanges on the valve, and bolts are used to connect the flanges on both ends of the valve to the pipe flanges.

Overview of electric high platform ball valve: The electric high platform ball valve adopts a high platform design, which can be directly installed with the actuator without the need for a bracket, which provides convenience for product installation and replacement, and has the characteristics of small flow resistance and large flow capacity. The difference between the electric high platform ball valve and the ordinary ball valve with bracket is that it occupies a small space and has a compact structure. The disadvantage is that it is not resistant to high temperature, and the temperature is transmitted to the cylinder, and the rubber ring in the cylinder is easy to age. Although the ordinary ball valve and the actuator need to be installed with a bracket and a connecting shaft, the heat dissipation function is stronger. Usually, the pipeline with a high temperature usually adopts a ball valve with a bracket, which can avoid damage to the actuator due to high temperature and prolong the service life. service life. Electric high platform ball valve features: 1. It adopts high platform ISO5211 standard design, and it can be connected and installed with the actuator without other brackets and connecting shafts. 2. It adopts silica sol precision casting, beautiful appearance, tight and reliable, good sealing performance and wide application range. 3. Anti-static function, a spring is set between the ball, valve stem and valve body, which can discharge the static electricity generated during the switching process. 4. The fluid resistance is small. The full-bore ball valve basically has no flow resistance, and the opening and closing is rapid. It only needs to rotate 90�° from fully open to fully closed, and it is easy to operate. The electric high platform flanged ball valve adopts the spring plunger type electrostatic lead-out device, so that the direct form of static passage between the ball and the valve body or the form of static passage between the ball and the valve body through the stem tube, so that the ball and the valve seat can be The static electricity generated by friction during the switching process is led to the earth through the valve body, preventing fire or explosion that may be caused by static sparks. Static electricity is an objective natural phenomenon, which can be produced in many ways, such as contact and friction. For example, for high platform ball valves, when the ball rubs against the soft-sealed switch, static electricity will be generated. If the pipeline is filled with flammable and explosive media, it is very dangerous. Therefore, a connecting device is installed in the valve to guide the static electricity of the ball to the outside to prevent static electricity. is very important.

Overview of electric three-piece ball valve: The electric three-piece ball valve (electric internal thread ball valve) is assembled from three parts: the left and right valve casings and the middle valve body. Four longer bolts traverse the three-section valve casing, and tightly clamp the middle valve body from both ends. The biggest advantage of the electric three-piece ball valve is that it is particularly easy to disassemble. When the valve fails or needs to be repaired, it is not necessary to disassemble the thread of the pipeline, but the four-piece ball valve can be taken off directly, and the body part can be taken out. It not only reduces the probability of failure, but also improves the working efficiency. It is especially suitable for working conditions with small mechanical volume and narrow space. Electric three-piece ball valve principle: The three-piece electric ball valve has reliable sealing performance and high pressure. Its action principle is to drive the valve core to rotate 90 degrees through the power supply voltage of the electric actuator to open and cut off the medium. It can be designed as The two-position switch control of the medium can also realize the proportional adjustment of the medium flow, pressure, temperature and other parameters in the pipeline. Electric three-piece ball valve standard specification: Test inspection: API598, EN12266 Threaded end: ASME B1.20, BS21 DIN2999/259, BSP ISO7/1, ISO228/1 JIS B 0203 Butt weld ends: ASME B16025 Sleeve Welding Ends: ASME B16.11 Flange connection: ASME B16.5 DIN2542~2545 JIS B2238 Classification and difference of electric chip ball valve: The movable one-piece ball valve is one-piece, and the ball is fixed by a plug, which facilitates its maintenance and can be used in working conditions that require quick opening and quick closing. The electric two-piece ball valve is composed of two parts, which are fixed by two pieces of valve bodies clamping the ball. The maintenance is relatively complicated. The tightness of the middle screw is related to whether there will be air leakage, The electric three-piece ball valve is similar to the two-piece ball valve. It consists of left and right end covers and a middle valve body, and then enters the sheep clamp with necks on both sides. Its pressure is higher than that of the other two types.
