The butterfly-shaped buffer check valve is composed of a valve body, a valve clack, a buffer device and a micro-regulating valve. The product has the characteristics of novel structure, small volume, small fluid resistance, stable operation, reliable sealing, abrasion resistance, good buffer performance and the like, and is mainly used for industrial water supply and water pump outlet of the sewage treatment plant, and the medium in the pipe network is prevented from flowing reversely. The destructive water hammer is automatically eliminated, so that the water pump and the pipeline are not damaged The butterfly type buffer check valve can be divided according to its structure and installation mode. 1. The disc of the butterfly buffer check valve is disc shaped and rotates around the rotating shaft of the seat passage. Because the inner channel of the valve is streamlined and the flow resistance is smaller than that of the lifting butterfly check valve, it is suitable for large caliber situations with low velocity and irregular flow, but not suitable for pulsating flow, and its sealing performance is not as good as that of lifting type. Butterfly check valve is divided into three types: single valve type, double valve type and multi half type. These three forms are mainly divided according to valve caliber, in order to prevent the medium from stopping flow or backflow, and to reduce the hydraulic impact. 2, butterfly buffer check valve: disc sliding along the vertical center line of the valve body check valve, the internal thread check valve can only be installed on the horizontal pipe, in the high pressure small caliber check valve disc can use a ball. Butterfly check valve body shape is the same as globe valve (can be used with globe valve), so its fluid resistance coefficient is large. The structure is similar to the globe valve, and the valve body and disc are the same as the globe valve. The upper part of the disc and the lower part of the cover are machined with a guide sleeve, and the disc guide can be lifted and lifted freely in the guide simple of the valve. When the medium flows down, the disc is opened by the medium thrust, and when the medium stops, the disc falls on the seat from drooping, which plays the role of preventing the media countercurrent. The direction of the medium inlet and outlet channel of the straight butterfly check valve is perpendicular to the direction of the valve seat channel, and the direction of the medium inlet and outlet channel of the vertical lifting check valve is the same as that of the valve seat channel, and its flow resistance is smaller than that of the straightway type.
The pneumatic double-clamp type hard-sealing butterfly valve adopts a precise j-shaped elastic sealing ring and a three-eccentric multi-level metal hard sealing structure, and is widely used for treating gold, electric power, petrochemical industry, water supply and drainage and municipal construction of the medium temperature and 425 DEG C, And is used for regulating flow and carrying off fluid. Characteristics of Pneumatic clamping hard Seal Butterfly Valve 1. The pneumatic clamping hard seal butterfly valve adopts three eccentric sealing structure, and the valve seat and butterfly plate have almost no wear and tear, so it has the sealing function of more and more tight. 2. The sealing ring is made of stainless steel, and has the dual advantages of metal hard seal and elastic sealing, and has the characteristics of corrosion resistance, long service life and the like, both at low temperature and high temperature. 3. The sealing surface of the disc is made of hardfacing cobalt-based hard alloy, and the sealing surface is resistant to wear and has long service life. 4. The large size butterfly plate adopts quilting structure, which has the advantages of high strength, large overcurrent area and small flow resistance. 5. The valve has two-way sealing function. The valve is not limited by the flow of medium during installation, and is not affected by the space position. It can be installed in any direction. 6.The drive unit can be installed at multiple stations (rotated 90 ° or 180 °) for ease of use by the user The gas butterfly valve is mainly divided into hard seal gas butterfly valve and rubber soft seal butterfly valve according to different sealing forms.

The mud pump valve rod guide (lower), which is installed in the chamber of the cylinder, acts as a centring and positioning suction valve body assembly. It consists of a guide body and an inner sleeve, which is inserted into the guide body. The material of the guide body is ZG35CrMo, and the inner sleeve is carburized and hardened by 20CrMnTi. Check the inner sleeve of the valve rod guide once a week. Replace it if there is obvious wear (the gap between the valve rod and guide is more than 3mm), so as not to lose the guiding function of the guide and accelerate the wear of the valve.

To ensure safety, the drilling pump is equipped with safety valve in the outlet, which is able to control the ultimate pressure of the pump within the admitted scope. The high pressure safety valve is forged by high quality structural alloy steel. As a kind of protection device and human safety device, it is generally installed on cementing devices, fracturing pump, high pressure operation piping, pressure vessel and devices under high pressure and high flow capacity. It controls elastic force of the valve seat by adjusting the nut on the top. Once the pumping pressure or piping pressure exceeds pre-established pressure value, safety valve opens automatically to release the pressure. When the pressure value reaches the normal value, valve rod will recover the position by spring and close the valve.
