Description

Technical Field

[0001] The utility model relates to the technical field of throttle valves, and more specifically to an anti-blocking throttle valve. Background Art

[0002] A throttle valve is a valve that controls the flow of fluid by changing the throttle section or throttle length. According to the channel type, throttle valves can be divided into two types: straight-through type and angle type; according to the shape of the opening and closing parts, there are three types: needle-shaped, groove-shaped and window-shaped.

[0003] When the throttle valve is used for a long time, impurities are likely to flow into the valve body along with the medium, which may block the flow port of the valve body and affect the normal use of the valve body. Therefore, a filter device is provided inside the existing throttle valve.

[0004] However, the filter device inside the existing throttle valve will be blocked after being used for a period of time. Since the throttle valve is mostly an integrated structure, it is inconvenient to disassemble the filter device. Utility Model Content
