Abstract

The invention relates to an integral plug-in type hand-operated direction valve. A control mechanism (1) and the upper end of a valve body component (2) are hinged with a hinged support (7) through a pin shaft (6); the hinged support (7) is connected with the upper end of the valve body component (2) through a bolt; a press block (4) is arranged at the lower end of the valve body component (2); the control mechanism (1) and the lower end of the valve body component (2) are in compressed connection through an eyelet bolt (5); valve core components (3) are arranged in the valve body component (2) which is in threaded connection with the valve core components (3) through an inner cavity of the valve body component (2); each control unit (8) comprises one control mechanism (1) and a pair of valve core components (3); and an outlet of the valve body component (2) is directly communicated with outlets of the valve core components (3). The integral plug-in type hand-operated direction valve has the characteristics of safety, speediness and reliability, capacities of providing a high-pressure and high-flow operating fluid and continuously working on site, low fault rate, convenience in assembly and maintenance and the like.

Description

technical field [0001] The invention belongs to the field of manual reversing valves for coal mines, and in particular relates to an integral plug-in manual reversing valve. Background technique [0002] At present, in the coal mine industry in China, the manual reversing valve is one of the important hydraulic control components of the hydraulic support for coal mines. In the hydraulic control system of the hydraulic support, the manual reversing valve can control the direction of the liquid flow to realize the lifting of the column, the expansion and contraction of the oil cylinder or the jack, and then complete the supporting, moving, pushing, anti-falling and jacking of the hydraulic support. Coal and other functional operations. Traditionally used in the coal mine industry, the manual reversing valve is usually called a "piece valve" because the existing manual reversing valve is a sheet structure, and each piece of manual reversing valve can control The telescopic a...
