American standard globe valve structure problem

    American standard flanged globe valves have become more and more common in industrial and agricultural production and people's lives, so their structure, performance and reliability have also attracted more and more attention.

    In the process of valve operation, the problems of running, leaking, emitting and dripping of the valve will not only cause a lot of waste of energy, but also bring difficulties to the maintenance of the surrounding environment. Therefore, the resolution of these problems has naturally become the top priority.

    The structural problem of the American standard globe valve is a major cause of these problems, so how to solve it?

    We know that due to the elasticity of the sealing material and easy deformation, and the structure of the American standard globe valve is very exquisite, attention should be paid to the fixing problem.

    A backing plate can be added under the sealing rubber, and the valve core can be connected with screws to play the role of fixing and sealing. Of course, the backing plate and sealing rubber must be compatible with the medium flowing in the pipeline. If there is a certain corrosive medium fluid flowing in the pipeline, the screws and backing plates should be made of corrosion-resistant materials.

    Through the simple modification of the above-mentioned American standard stop valve structure, the effect is very large, and the problems of valve running, leakage, emission, and dripping are greatly reduced.
