Description

Technical Field

[0001] The utility model belongs to the technical field of valves, and particularly relates to a valve capable of reducing scouring and wear of a valve plate. Background Art

[0002] Valves are pipe accessories used to open and close pipelines, control flow direction, and adjust and control the parameters (temperature, pressure, and flow) of the conveying medium. Most common valves are directly connected to pipelines during use, and most valves are located near water sources. When the water from the water source directly passes through the inside of the valve, the water flow rate is fast and the impact force is high, which will have a greater scouring effect on the valve plate inside the valve. The valve plate will be worn to a certain extent under the long-term scouring effect of the water flow, causing its external dimensions to change and unable to achieve an absolute barrier effect on the water flow. When the valve is closed, a small amount of water may still flow out, which will cause the control function of the valve to fail and affect normal use.

[0003] Secondly, when the accuracy of the valve plate is slightly reduced due to the scouring of water flow, less water will flow out when the valve is closed. For the user, whether to inspect or replace the valve becomes a problem. The inspection time may be long, which may delay normal use, and the cost of replacing the valve is correspondingly high.

[0004] In summary, there are certain problems in the use of valves that cannot reduce the wear of the valve plate due to scouring, so it is hoped to propose a new structure to solve the above technical problems. Utility Model Content
