Problems solved by technology

The manual control handle of the commonly used manual reversing valve mainly has three positions, the middle position, the left position and the right position. The left position and the right position are the working positions. When the manual operation handle is in the middle position, the reversing valve body is closed. state, when it is in the left or right position, the valve body of the reversing valve is in a flow state. According to the inspection and inspection requirements of industry standards, the reversing valve for hydraulic supports must undergo a reversing performance test. Under rated pressure and flow conditions, the reciprocating Operate the operating handle of the tested valve to observe whether the action of the tested valve is flexible, whether the opening and closing actions are normal, etc. The commonly used test method is to manually perform the reversing action of the reversing valve. long wait

Abstract

The invention discloses a reversing valve performance testing device, and relates to the field of reversing valves for hydraulic supports. The reversing valve performance testing device is invented for providing a suitable performance testing device for the reversing valves. The reversing valve performance testing device comprises a supporting body (1), a first clamping plate (2), a second clamping plate (3), a double-acting hydraulic cylinder (4), a push-and-pull reversing support (5) and a bolt (6). The reversing valve performance testing device is high in reliability, high in testing efficiency, short in testing time, high in automation degree and suitable for reversing valve performance testing.

Description

technical field [0001] The invention relates to a reversing valve for a hydraulic support, in particular to a performance testing device for a reversing valve for a hydraulic support. Background technique [0002] The reversing valve is the liquid flow distribution mechanism of the hydraulic support, which mainly controls the action of various power hydraulic cylinders by connecting or cutting off the flow channel. The manual control handle of the commonly used manual reversing valve mainly has three positions, the middle position, the left position and the right position. The left position and the right position are the working positions. When the manual operation handle is in the middle position, the reversing valve body is closed. state, when it is in the left or right position, the valve body of the reversing valve is in a flow state. According to the inspection and inspection requirements of industry standards, the reversing valve for hydraulic supports must undergo a r...
