Description
The utility model relates to and a kind ofly is applicable to that with emulsified liquid or oil be the hydraulic system of working medium, and particularly the coal mine hydraulic supporting hydraulic system advances back the integrated valve plate of liquid.This valve plate and selector valve stack mounting can be used for the operation of various hydraulic equipments.
Hydraulic support whenever sets up the action that one group of selector valve (control valve) is controlled this each oil cylinder at present.Every group of selector valve all is furnished with stop valve, filter reaches back the liquid cutout valve, and their dispersed placement are in the position away from control valve.Existing stop valve is spherical stop valve and multi-circle spiral flow formula stop valve.The deficiencies in the prior art part is: arrange and disperse, operation inconvenience, and time-consuming, effort.Therefore stop valve all is in normally open at ordinary times, just ability Temporarily Closed when the hydraulic system of maintenance hydraulic support.Every of chip combined directional valve all has two separating valves that return liquid system and high-pressure system are kept apart, and by 100 hydraulic supports in full face, every 8 meters, just there are nearly 1600 separating valves the full face.Conditions down-hole is abominable, and some separating valve may produce seepage unavoidably, and total seepage of the full face of causing therefrom, scurrying the liquid phenomenon will be quite serious, even influence is to the normal running of support.In addition, filter does not clean for a long time and can flow because of contamination and plugging liquid.The spool that returns the liquid cutout valve adopts polyformaldehyde material, conical surface seal.This material produces easily that distortion makes on the sealing surface embedded with metal bits and coal petrography particle and the loss of seal performance causes the phenomenon of leakage under turnoff state.
The deficiency that the purpose of this utility model is to overcome prior art provide a kind of can with the selector valve stack mounting, easy to operate, collection stop valve, filter and return the liquid cutout valve be one advance back the integrated valve plate of liquid.
The purpose of this utility model also is to make the filter of this valve plate to have the recoil automatic cleaning function.Further improve back the sealability of liquid cutout valve.
The purpose of this utility model can reach by following measure:
The disconnected valve of stop valve, filter and time liquid is assemblied in the valve plate body, and stop valve adopts the handle type two position two-way valve.The valve plate body has bilateral or the one-sided attachment face that is connected with selector valve, and the supply opening and the liquid return hole that communicate with selector valve are arranged on it.Two sides in addition of valve plate body have P mouth and R mouth respectively.Interconnected asphalt channel is arranged in the valve plate body.
The purpose of this utility model can also reach by following measure:
There is passage to be connected between filter exocoel and the P mouth, is provided with stop valve in the passage.Return the liquid cutout valve and adopt the rubber pad plane sealing, be inlaid with the rubber valve pad in the spool end.
The drawing of accompanying drawing is described as follows:
Fig. 1 is an embodiment of the present utility model.
Fig. 2 is the left view of Fig. 1.
The utility model is described in further detail below in conjunction with embodiment:
1 is the handle type two position two-way valve among Fig. 1-2, the 2nd, and filter, the 3rd, return the liquid cutout valve.They are assemblied in the valve plate body 4.The C face of valve plate body 4 is the attachment face that is connected with selector valve with the D face.The supply opening A that leads to selector valve is arranged respectively on it

4And G
2Between cone valve 20 is arranged.
Returning liquid cutout valve 3 is made up of valve pad 21, spool 22, spring 23, joint 24, pressure nail 25.Spool 22 is a stainless steel material, and valve pad 21 is a rubber pad.Press nail 25 to make valve pad 21 be embedded in spool 22 ends.
The working principle of this valve plate is as follows: the high-pressure work liquid one tunnel that comes from the P mouth is sealed by the closure of the spool 6 of two position two-way valve 1, rubber valve pad 8, and another road is sealed by the closure of cone valve 20 with valve plate body 4.After with cam handgrip 13 valve pad 8 being left in spool 6 pullings, high-pressure work liquid is by passage G
