The "AMTG-2" is a portable feeler gauge. It is used to measure the thickness of non-magnetic materials, such as plastic, glass, ceramic, aluminum, titanium, copper etc... The accuracy of the measurement is not affected by the shape of the samples. It’s designed by basing on the method of the Hall Effect. Simple and rapid measure as below: - Place the steel ball on one side of the sample and the probe on the opposite side - Move the sample and let the probe to be the tested position - The steel ball will be drawn by the probe automatically - The Hall Effect sensor on the probe measures the distance between the probe tip and the steel ball

Central heating : Large heating equipment output pipelines, trunk , branch . Heat exchangers : Pipeline and its opening and closing the loop . Steel plant : a variety of fluid pipes, exhaust pipes, gas and Heat supply pipelines, fuel supply pipe. A variety of industrial equipment: various heat treatment pipes , industrial gas and heating pipes. Single flange fully welded ball valve construction and design : Single flange welded ball valve is completely designed and manufactured in accordance with API6D , fire anti-static . Stem lengthened according to user requirements , body and other metal parts used in all spheres of high-quality forged materials to ensure the quality and strength of ball . Sphere with packing boxes or support plate fixation. Packing boxes or support plate fixed ball can eliminate bending media sphere force acting on the valve stem to produce , so the stem is exposed only torque. And in the sphere of fixed low-friction Teflon around Le composite bearings. Smooth operation of the valve , a small switch torque , easy to operate. Seal is a unique two soft seal and metal seal form triple sealing . Ensure reliable sealing, safe to use. Long-life , maintenance-free .
Buried fully welded ball valve background in the development of heating systems 1.often buried underground heating pipe network control valves required for the construction of tall valve wells, rain or snow will refuse into the valve well , they refuse , will produce large amounts of harmful gases in the well . The operator enters the valve shaft could cause personal injury when handling valves. Burst pipes and valves will cause harm to the operator . 2.the heating pipe network due to construction , welding, corrosion and other reasons that often exists debris pipe network will carry the debris washed medium flow valve seal structure , causing the valve to close the valve sealing surface damage lax off valve became furnishings . 3.normal valves and pipe connections required flanges, screws, gaskets, valves and pipe connections to waste a lot of material resources is not conducive to the global environment and energy conservation . To do this well developed buried fully welded ball valve. Buried fully welded ball valve uses: City gas : gas export pipeline , the main trunk and each branch supply pipes. Central heating : Large heating equipment output pipelines, trunk , branch . Heat exchangers : Pipeline and its opening and closing the loop . Steel plant : a variety of fluid piping , choose to put gas pipelines, gas and heat supply pipelines, fuel supply pipe. A variety of industrial equipment: various heat treatment pipes , industrial gas and heating pipes. Buried fully welded ball valve mounting dimensions : Buried advantage of fully welded ball valve : 1.buried fully welded ball valve can be buried in the ground , without the construction of tall valve well , in order to reduce construction costs, resulting in personal injury can be avoided while at the same time operate the valve . 2.buried fully welded ball valve is open, the ball completely surrounded the seat , although the media has less impurities erosion and ball valve sealing surface , because of this special structure of the valve and the pipe has the same tightness life . 3. solder ball buried close to the static dielectric ball valve seat and seal damage , still open when the process deposited dielectric sphere debris scraped off again with the spring seat to compensate for variations in pressure and temperature with compensation, guaranteed not to have any leaks. 4.buried fully welded ball valve can be welded directly to the pipe flanges savings , screws , washers , saving a lot of material resources. 5.buried fully welded ball better than butterfly valve disc in the middle of the medium flowing medium debris will scour the disc , causing damage to the disc , the valve closed lax ; 6.buried fully welded ball valve is superior , in addition to medium debris washed sealing surface , causing damage to the sealing surface so close lax. When the media stationary medium debris will accumulate in the tank causing the gate closed gate valve is not in place , so that the valve closed lax . 7.light weight, good looks and easy insulation makes equipment more refined appearance . 8.due to the special structure of the valve to the high life , normal warranty of 10 years. wooden box with filling or according customer's requirement
Structure: The valve is made up of all welded body and PTFE gasket, can run long life under the condition of frequent operation¡¡éimpurities and chemicals. Fine grinding stainless steel sphere can guarantee for years to open and close freely and reliable operation. The structure of floating ball,.The elastic washer in the slope can guarantee for the sealing ring compression on the sphere,the valve can guarantee closely even though in the case of pressure is not stable. Containment spindle is made up of two o-ring seals,The top of small diameter of the valve can be changed. Both can be replaced of DN65--DN300. THE PTFE thrust washer is between the stem shoulder and stem chamber,it also can play the role of sealing. The stem chamber of the ball valve that more than DN65 equipped with stainless steel bearing. Features: Don't need maintenance, adjustments and lubrication,Easy to install,Long-term reliable operation in the Low operating cost. The valve stem can be longer, easy to heat preservation. Operating handle can be removed, reversing the installation. The body does not contain heavy and unreliable castings. It is very convenient of the install mediation organization.

Ball valve open-close part for sphere, through a sphere around the body center for rotation to achieve open, closing a valve.Used for intercepting and change the flow distribution ratio or quick opening and closing. Its characteristic is wear-resisting, good sealing, light switch, long service life.Widely used in petroleum, chemical industry, power generation, paper making, aerospace and other fields. The advantages of the ball valve: 1, with the bottom flow resistance 2, realize completely sealed reaction in the high pressure and temperature range 3, can achieve rapid opening and closing and no impact to operation 4, not easy to get stuck at work, so reliably used in corrosive medium and low boiling point 5, double sealed more reliable 6, when the ball valve is fully open and close, sealing surface and the dielectric isolation, so the high speed won't bleed air seal face erosion by the media. 7, compact structure, light weight, can be thought of as the most ideal valve ball valve is used for low temperature medium. 8, all welded body ball valve, can be directly buried underground make internal valve from erosion, the highest service life can be up to 30 years. Our advantage: The company on the basis of combined with the structural advantages of ball valve, ball valve leakage protection aspects focus on improvement, the first is to use three free maintenance o-rings, adding self-styled mat, stainless steel valve stem to prevent rust and on both sides of a sphere with butterfly spring, easy to cause the medium leaking key protection area.And the company can according to customer demand, customized. The company in the valve design and manufacturing of 32 national patents, ISO9001:2000 secondary quality system certification and CE, ANSI, UN and other international certification.Is the present domestic most professional heating valve manufacturing enterprise. wooden box with filling or according customer's requirement
