Abstract
The utility model discloses a self-locking manual pilot valve used for controlling a coal mine underground main valve, comprising a valve body (1), an operating handle assembly and a valve core assembly, wherein the valve core assembly consists of a screw plug (6), a spring (5), a sliding rod (8) and a push rod (12) which are sequentially arranged from bottom to up; the sliding rod (8) is externally and sequentially provided with a valve sleeve (7), a Glyd ring, a valve seat (10) and a front valve seat (11); the operating handle assembly consists of an end cover (2), a pressure rod (3) and a handle (4); the end cover (2) of the operating handle assembly is fixedly connected on the valve body (1); the position where the front end part of the handle (4) is contacted with the valve body (1) is a plane; and one end of the pressure rod (3) is connected with the handle (4), and the other end thereof is connected with the end cover (2). In the pilot valve, the operating handle has the function of self locking, thus being convenient for operation; and simultaneously, by adopting the sliding valve structure, the pilot valve reduces the operation moment of the handle and achieves the purpose of labor-saving operation.
Description
Technical field
The utility model belongs to the main valve control device of underground mine use, particularly a kind of manual pilot valve that is used for the band auto-lock function of the adjacent frame system of the manual guide of hydraulic support.
Background technology
The manual pilot valve of self-locking is the core parts in the hydraulic support hydraulic control system.Be mainly used in the keying of control valve core of main valve, for the every function that realizes hydraulic support provides hydraulic power.At present the manual pilot valve that uses mainly is that what to adopt is ball-valve structure, is not with auto-lock function, needs to lift with hand the handle of manual pilot valve in actual mechanical process, the work that pilot valve could continue always.
Though the manual pilot valve of this form can satisfy actual needs substantially, but have following problem: (1) is not because operating grip is with auto-lock function yet, the operator need lift handle always, finishes up to the action of hydraulic support, the easy like this operator's fatigue that causes; (2) because the pilot valve seal form adopts is the ball sealing, therefore cause operational torque bigger, the operator in use needs just can finish operation to pilot valve with bigger power.(3), determined that the part of spool part of pilot valve of this form is more, and machining accuracy is higher, has therefore increased the manufacture difficulty and the manufacturing cost of whole pilot valve owing to be the ball seal form.
The utility model content
The purpose of this utility model is, overcomes the deficiencies in the prior art, provides a kind of self-locking easy to operate, laborsaving, that manufacturing cost is lower manual pilot valve.
Technical solution of the present utility model is: the manual pilot valve of self-locking comprises valve body, operating grip assembly and core assembly; Core assembly is installed in the valve body; Core assembly comprises plug screw, spring, slide bar and the push rod of installing successively from bottom to top, and slide bar is followed successively by valve pocket, Ge Laiquan, valve seat and preceding valve seat outward; The operating grip assembly is made up of end cap, depression bar and handle; The end cap of operating grip assembly is fixedly connected on the valve body; Handle leading section and valve body contact position are a plane, and depression bar one end connects handle, and an end connects end cap; When handle lifted, depression bar was pressed on the push rod of core assembly, formed a stable triangular structure between depression bar and the valve body, formed self-locking.
Described core assembly adopts with valve body and is threaded.
Described valve body, end cap, depression bar, handle, spring, plug screw, valve pocket, slide bar, valve seat, preceding valve seat and push rod all adopt stainless steel material.
The utility model beneficial effect compared with prior art is:
(1) easy to operate.The operating grip of the manual pilot valve of the utility model has auto-lock function, only need lift handle in operating process can loose one's grip, automatically finish self-locking, put down handle again after waiting hydraulic support action to finish to get final product, the operator does not need to lift handle always in the hydraulic support course of action.
(2) rapid operation.Because what this pilot valve adopted is sliding valve structure, during pilot valve work, slide bar down moves, and the hydraulic coupling at slide bar two ends is in equilibrium state, therefore only need bear very little spring force, has so just reduced the operational torque of handle, has reached the purpose of rapid operation.
(3) manufacturing is simple, cost is low.Because what whole pilot valve adopted is sliding valve structure, slide bar is the parts of core the most, can reach the effect of sealing, see the crudy of slide bar when main, and in actual process, bar processing is comparatively simple and convenient, be worked into permissible accuracy, difficulty is lower, and cost is also lower.
Description of drawings
Accompanying drawing 1 is the schematic diagram of the manual pilot valve of the utility model self-locking.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
As shown in Figure 1, the manual pilot valve of self-locking of the present utility model comprises valve body 1, operating grip assembly and core assembly; Core assembly adopts to be threaded and is installed in the valve body 1.
Core assembly comprises from bottom to top plug screw 6, spring 5, slide bar 8 and the push rod of installing successively 12, and slide bar 8 is outer to be followed successively by that valve pocket 7, lattice enclose 9, valve seat 10 and preceding valve seat 11.Need sealing place to add sealing ring between each parts.
The operating grip assembly is made up of end cap 2, depression bar 3 and handle 4; End cap 2 is connected on the valve body 1 by screw; Handle leading section and valve body 1 contact position are a plane, and an end of depression bar 3 connects handle 4, one ends and connects end cap 2; When handle 4 lifted, depression bar 3 was pressed on the push rod 12 of core assembly, formed a stable triangular structure between depression bar 3 and the valve body 1, formed self-locking.
In whole manual pilot valve, valve body 1, end cap 2, depression bar 3, handle 4, spring 5, plug screw 6, valve pocket 7, slide bar 8, valve seat 10, preceding valve seat 11 and push rod 12 all adopt stainless steel material.
The operating principle of the manual pilot valve of the utility model self-locking is: manually pilot valve is a two position three-way valve, A chamber and T chamber are linked up when not working, A chamber and P chamber disconnect: when manual pilot valve handle 4 lifts and reaches the limitation locking position, whole pilot valve is in running order, the course of work is: when handle 4 lifts, slide bar 8 down moves, when motion puts in place, slide bar 8 lower end sealing rings and 7 sealings of back valve pocket, A chamber and T chamber have been disconnected, rely on the elongated slot on the slide bar 8 to link up A chamber and P chamber, pilot valve work simultaneously.
After the execution architecture motion puts in place, put down handle 4, slide bar 8 resets, and A chamber and T chamber are linked up again, and A chamber and admission chamber P chamber disconnect, the pilot valve end-of-job.
The foregoing description is a kind of enumerating of the present utility model, and those skilled in the art can carry out various improvement and replacing not departing from according to different designing requirements and design parameters under the situation of the present utility model, fall into protection domain of the present utility model equally.
