Problems solved by technology

[0004] Many existing gate valves will have water hammer phenomenon when closing the valve. At the same time, due to the thrust of the medium when closing the valve, it is difficult to close the valve and cause serious wear of the valve stem and nut mechanism.
In the face of coarse media, the sealing performance cannot be effectively guaranteed

Abstract

The invention belongs to the field of coarse medium fluid safety gate valves, and particularly relates to a coarse medium fluid safety gate valve. The coarse medium fluid safety gate valve comprises a valve body, a circumferential fixing block is arranged in the valve body, a water blocking device is arranged in the circumferential fixing block, a torsion resisting device is arranged on one side of the water blocking device, a water hammer preventing device is arranged on one side of the water blocking device, and a coarse medium removing device is arranged on the upper portion of the water hammer preventing device. The coarse medium fluid safety gate valve is characterized in that a housing is fixed to the upper portion of the valve body through bolts. In the using process, the water hammer can be prevented, abrasion is not prone to occurring, and transportation of coarse medium fluid is efficiently completed.

Description

technical field [0001] The invention belongs to the field of coarse-medium fluid safety gate valves, in particular to a coarse-medium fluid safety gate valve. Background technique [0002] Gate valve is currently the most important type of valve, which is widely used in the circulation and cut-off of liquid, gas, dust and other media. [0003] Usually, the gate valve includes a valve body, and the lower part of the valve body has a feed port and a discharge port, and the left end of the feed port and the right end of the discharge port both have sealing surfaces, and the dynamic sealing fit between the two sealing surfaces is equipped with an upper and lower Main valve plate that moves and does not rotate. Simultaneously, a valve stem is connected to the top of the valve plate, and a handle is connected to the top of the valve stem through a screw nut mechanism. [0004] Many existing gate valves will have water hammer phenomenon when closing the valve, and at the same tim...
