Wenzhou Tielong Valve Co., LTD

According to the sealing surface configuration can be divided into wedge gate valve and parallel gate valve, wedge gate valve can be divided into: single gate type, double gate type and elastic gate type; Parallel gate valves can be divided into single and double gate valves. According to the thread position of the valve stem, it can be divided into two kinds: open stem gate valve and dark stem gate valve.

 

The installation and maintenance of the gate valve should pay attention to the following matters: the handwheel, handle and transmission mechanism are not allowed to be used for lifting, and collision is strictly prohibited.

 

The double gate valve should be installed vertically (i.e. the stem is in a vertical position with the handwheel at the top).

 

Gate valves with bypass valves should be opened before opening (to balance the pressure difference between the inlet and outlet and reduce the opening force).

 

The gate valve with transmission mechanism shall be installed according to the instructions of the product.

 

If the valve is used frequently, lubricate it at least once a month.

 

For a long time, the general gate valve used on the market, there is water leakage, easy to rust phenomenon, the factory introduced foreign advanced technology produced by the soft seal gate valve, to overcome the general gate valve seal poor elastic fatigue, easy to rust and other defects. Soft seal gate valve uses the elastic gate plate to produce a small amount of deformation, to achieve a good sealing effect, the valve has a light switch, reliable sealing elastic memory and long service life and other significant advantages such as flat bottom valve seat - traditional gate valve is often in the water washing pipe because of foreign objects such as stone, wood, cement, paper, debris and other sludge in the bottom groove of the valve, It is easy to cause leakage phenomenon that can not be closed tightly, and the bottom of the soft seal gate valve uses the same flat bottom design as the water pipe, which is not easy to cause debris deposition, so that the fluid is unobstructed.
