Abstract
The utility model discloses a manual pilot valve for a thin seam used for a coal mine shaft under the control of a main valve, comprising a valve body assembly and a valve core assembly, wherein the valve body assembly comprises a valve body (8) and an end cover (3) which are fixedly connected; the valve core assembly comprises a push rod (1), a left ceramic ball (14), a valve seat (11), a shuttle rod (12), a ball seat (6), a right ceramic ball (15), a spring (7) and a plug (2) which are sequentially arranged; a rotating shaft (9) and a handle (5) are connected on the push rod (1); a screw plug (4) is sleeved outside the push rod (1); and a valve sleeve (13) is sleeved outside the shuttle rod (12). By adopting a ceramic ball valve for sealing, the processing difficulty is reduced, the high-precision matching requirement of a valve ball and the valve seat is ensured, the service life of the ceramic balls can be improved, and the reliability is improved as well. Meanwhile, all the structural parts of the utility model adopt the high corrosion-resistant and high-strength stainless steel, thereby meeting the safety standards of the coal mine and adapting to the severe medium environment of under the shaft.
Description
Technical field
The utility model belongs to the main valve control gear of underground mine use, particularly a kind of manual pilot valve that is used for girdle with the adjacent frame system of the manual guide of hydraulic support.
Background technique
Manually pilot valve is the core parts in the adjacent frame system of the manual guide of hydraulic support for low coal seam.The spool that is mainly used in control main valve high flow directional control valve is opened, thereby controls the action of whole hydraulic support actuator.
The girdle that uses is that the electromagnetic priority valve valve core structure adopts plane sealing with existing electromagnetic priority valve valve core structure research basis with manual pilot valve at present, and working axiality and perpendicularity all require than higher, and rate of fault is higher." a kind of manual pilot valve " as Chinese patent application numbers 200820124460.5 discloses a kind of manual pilot valve, comprises valve body and spool, and spool comprises depression bar that order installs, returns the liquid ball, returns liquid valve, push rod, feed liquor valve, feed liquor ball and spring; On depression bar, connect lever and handle, the moment of torsion that a torsion spring is used to increase handle is installed on handle.This patent has increased the moment of torsion of handle by torsion spring, make valve avoid taking place misoperation, and compact structure is reasonable, can reduce the volume of whole valve.But also there is following shortcoming in existing manual pilot valve: (1) valve core structure adopts steel ball sealing, steel ball irons for the surface plating, in the using process of down-hole, because working medium has corrosivity and contaminativity, the steel ball surface plating is ironed layer and is easily come off, cause sealing valve port not tight, pilot valve is scurried the liquid phenomenon, influences the down-hole function of use.(2) manually the pilot valve body material adopts copper spare, and the cost of raw material is higher.(3) operating grip adopts bilateral operation, and mode of operation does not possess conformity.
The model utility content
The purpose of this utility model is, overcomes the deficiencies in the prior art, and a kind of good airproof performance, reliability height, the manual pilot valve of girdle simple to operate are provided.
Technical solution of the present utility model is: the manual pilot valve of a kind of girdle, comprise valve component and mangetic core assembly, and mangetic core assembly is packed in the valve component; Valve component comprises fixedly connected valve body and end cap; Mangetic core assembly comprises push rod, left ceramic ball, valve seat, shuttle bar, ball seat, right ceramic ball, spring and the plug that order is installed, and between left ceramic ball and the valve seat pad is arranged; On push rod, connect rotating shaft and handle; Push rod overcoat plug screw; The shuttle bar is outward a valve pocket.
Described valve body adopts 3 M3 screws to be connected with end cap.
The material of described valve body, push rod, valve seat, shuttle bar, left ceramic ball, right ceramic ball and spring is a stainless steel.
The characteristics of the utility model pilot valve:
(1) the utility model adopts the ceramic ball valve sealing, so both can reduce difficulty of processing, can guarantee that again the highi degree of accuracy of valve ball and valve seat cooperates requirement, in the working life that also can improve ceramic ball, has improved reliability.
(2) manual pilot valve structural member of the present utility model all adopts the highly corrosion resistant high-strength stainless steel, both can satisfy the safety of coal mines standard, can adapt to the abominable media environment in down-hole again.
(3) operating grip of the present utility model adopts same direction operation, has guaranteed the conformity of operational cognition, makes its hommization more.
Description of drawings
Accompanying drawing 1 is a structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model is described further.
As shown in Figure 1, the manual pilot valve of a kind of girdle comprises valve component and mangetic core assembly, and mangetic core assembly is packed in the valve component; Pilot valve of the present utility model adopts split-type structural, and valve component comprises fixedly connected valve body 8 and end cap 3; Mangetic core assembly comprises push rod 1, left ceramic ball 14, valve seat 11, shuttle bar 12, ball seat 6, right ceramic ball 15, spring 7 and the plug 2 that order is installed, and between ceramic ball 14 and the valve seat 11 pad 10 is arranged; On push rod 1, connect rotating shaft 9 and handle 5; Push rod 1 overcoat plug screw 4, shuttle bar 12 overcoat valve pockets 13.
Valve body 8 adopts 3 M3 screws to be connected with end cap 3 in the present embodiment.
The material of valve body 8, push rod 1, valve seat 11, shuttle bar 12, left ceramic ball 14, right ceramic ball 15 and spring 7 is a stainless steel in the present embodiment.
The working principle of the utility model pilot valve is: as accompanying drawing 1, this valve is made up of two ball valves, and valve seat 11 adopts hard material, is the high-hardness stainless steel material in the present embodiment.When being in original state, ceramic ball 15 makes valve seat 11 close under the effect of spring 7, and ceramic ball 14 is opened, and makes active chamber and time sap cavity logical.When operating grip 5, push rod 1 stressed moving down, pressure spring 7.When spring force reaches the numerical value of a setting, promote ceramic ball 15 by shuttle bar 12 and fully open, valve seat 11 is opened.Make 14 pairs of valve seats of ceramic ball 11 produce a stable closing pressure simultaneously, valve seat 11 is closed, the active chamber admission chamber is logical.This moment, working solution was flow to the control chamber of main control valve through active chamber by admission chamber.
When manually-operable stopped, because spring 7 active forces are big, valve automatically reset, and ceramic ball 15 is closed valve seat 11, and ceramic ball 14 is opened valve seat 11.
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 parameter under the situation of the present utility model, fall into protection domain of the present utility model equally.
