1) Remove the protective cover on both sides of the flange end and rinse and clean the valve in a fully open state. 2) Before installation should be in accordance with the specified signal (electricity or gas) for the whole machine test...
1) installation location, height, import and export direction must meet the design requirements, threaded connection should be firmly tight. 2) All kinds of manual valves installed on the insulation pipe, the handle must not be down.
Flange in the continuous production of modern industrial corrosion erosion by the medium temperature and pressure vibration, the influence of such factors as inevitably leak problems due to the sealing surface machining error of the size.
After installation, the globe valve should be checked regularly for the main inspection items: (1) Cut-off valve sealing surface wear condition. (2) The trapezoidal thread wear of stem and stem nut.
The function of any valve is to cut off the flow. Depending on the valve core, it can be divided into globe valve, gate valve, plug valve, ball valve, butterfly valve, needle valve and so on.
1. Adapt to harsh working environments The ball valve only needs to be rotated 90 degrees of operation and a very small rotation torque can be closed tight. Fully equal valve body cavity provides the medium with very little resistance
China valve industry chain is numerous, but non-valve power. On the whole, China has entered the ranks of the world valve power, but from the point of view of product quality China is still a long way from the valve power.
The dielectric pressure before and after the check valve is close to equilibrium and "sawing" each other, the disc is often slapped with the seat, and some brittle materials (such as cast iron, brass, etc.) are broken by a disc.
Since ball valves are usually made of rubber, nylon and PTFE as seat sealing rings, the temperature at which they are used is limited by the material of the seat seal ring. The cutoff effect of the ball valve is accomplished by pressing the...
Advantages: (1) has the lowest flow resistance (the actual is 0); (2) because in the work will not get stuck (in the absence of lubricant), it can be used reliably in corrosive media and low boiling liquid;
Ball valve has long been washed by materials, resulting in friction, resulting in serious impact wear, can not meet the normal production, at the same time resulting in the shortening of equipment use period.
1. No friction between opening and closing. This feature completely solves the problem that the traditional [wiki] valve [/wiki] affects sealing due to friction between the sealing surfaces. 2. Mounted structure.
Having obtained multiple certifications, our valve products are trusted by
global brands and have helped ensure smoother operations in numerous facilities.
