Product Overview
Ganma body is widely used as a regulating and intercepting device on fluid pipelines such as tap water, sewage, construction, petroleum, chemical, food, medicine, textile, electricity, ships, metallurgy, energy systems, etc. Pressing the sealing surface of the gate towards the valve seat on the other side to ensure the sealing of the sealing surface is called self sealing. Most gate valves use forced sealing, which means that when the gate valve is closed, it is necessary to rely on external force to forcefully press the gate plate against the valve seat to ensure the sealing performance of the sealing surface.
When the Ganma body is closed, the sealing surface can be sealed solely by the pressure of the medium, that is, solely by the pressure of the medium
When opening the gate valve, when the lifting height of the gate valve is equal to 1:1 times the diameter of the gate valve, the fluid channel is completely unobstructed, but this position cannot be monitored during operation. In actual use, the vertex of the valve stem is used as a marker, that is, the position where it cannot be opened, as its fully open position. To account for the locking phenomenon caused by temperature changes, it is usually done by opening the gate valve to the top position and then reversing it by 1/2-1 turn as the position for fully opening the gate valve. Therefore, the fully open position of the gate valve is determined by the position (i.e. stroke) of the gate plate. The sealing surface is prone to wear and tear, which affects its service life. When opening and closing, the two sealing surfaces of the gate and valve seat rub and slide against each other, which is prone to abrasion and wear under the pressure of the medium, affecting the sealing performance and shortening the service life.
For a long time, the general gate valves used in the market have generally suffered from water leakage or rusting. To overcome the defects of poor sealing and rusting of general gate valves, Ganma Body uses the compensating effect of slight elastic deformation generated by elastic gate plates to achieve good sealing effect. It has significant advantages such as lightweight switching, reliable sealing, good elastic memory, and service life. It can be widely used as a regulating and intercepting device on pipelines such as tap water, sewage, construction, petroleum, chemical, food, medicine, textiles, electricity, ships, metallurgy, energy systems, etc. This is the benefit and advantage of Ganma body.
