Abstract
The utility model relates to an oil water emulsion drill control valve group used for coal face, by which the oil water emulsion drill has the function of matching with the oil water emulsion pump stations used for any coal face. The utility model is characterized in that the oil water emulsion drill control valve group used for coal face comprises a speed regulation unit composed of an overflow valve (2) and a throttle flow valve (3) which are connected in parallel. The pipelines in the valve body are short and the superposition is minimal because of arranging a plurality of elements on the same horizontal plane. The essence safe oil water emulsion drill of utility model has the advantages of convenient operation, large regulation range, small size, and light weight.
Description
The utility model relates to a kind ofly can bore the control valve group with the matching used emulsion of emulsion power pack with any coal-face.
The jewel hole instrument that coal-face is used under the coal mine is mainly electric coal drill at present, establishes dry-type transformer, starter, leak detection relay and nearly 200 meters electric fixturess such as cable owing to use electric coal drill to assist, so there is unsafe factor; The underground work environment is abominable in addition, and high humidity, electric elements are easily impaired, and it also is a problem that electric coal drill is deposited in the down-hole; Electric coal drill weight, volume are bigger in addition, the labour intensity height.Therefore, coal-face uses electric coal drill, and is not only dangerous but also influence production efficiency.
Use emulsion to bore the shortcoming that can overcome electric coal drill at coal-face, belong to essential safe type, and coal-face all is provided with emulsion power pack, to finish work such as passing transporter, supporting roof, so power source can be shared.Just being furnished with emulsion in the thin coal bed fully-mechanized mining equipment of Shuangyashan Mining Administration seven-star ore deposit introduction Britain BJD company bores.But this brill only is applicable to ad hoc emulsion power pack, and emulsion brill itself can not carry out the adjustment of output speed and output torque.This has just limited the scope of application of this brill, can not with the supporting use of the emulsion power pack of other types, especially be not suitable for the emulsion power pack in domestic most coal-face.
The purpose of this utility model provides a kind of novel coal-face and bores the control valve group with emulsion.It can make the emulsion drilling tool have and adjust the function of output speed and output torque, thereby can be applicable to all emulsion power packs.In addition, because this control valve group compact conformation, volume are little, therefore can alleviate the weight that emulsion bores.
The utility model is designed a kind of emulsion that is made of switch valve (1), safety protective valve (5), counterbalance valve (4), overflow valve (2) and choke valve (3) and is bored the control valve group.Overflow valve (2) is connected in parallel with choke valve (3), constitutes the speed governing unit that emulsion bores the control valve group, has realized the rotational speed regulation that emulsion bores, and has improved the performance of regulating.Adopt the emulsion of this control valve group bore can with all coal-face with the supporting use of emulsion power pack.
The emulsion that the utility model proposes bores the control valve group and has adopted following optimum structure design (as shown in Figure 2)
Bore the width symmetric arrangement hole for back flow (8) and inlet opening (9) of control valve group along emulsion, the centre distance in two holes is 40mm.Bore control valve group width horizontal arrangement switch valve (1), overflow valve (2) and choke valve (3) along emulsion.Horizontal arrangement counterbalance valve (4) on hole for back flow (8) center line vertical direction, horizontal arrangement safety protective valve (5) on inlet opening (9) center line vertical direction, the center to center distance between counterbalance valve (4) and the safety protective valve (5) is 40mm.Size length * wide * height that emulsion bores the control valve group is 115mm * 95mm * 30mm.
Accompanying drawing 1 is a hydraulic system principle figure of the present utility model.
Accompanying drawing 2 is structure sectional views of the present utility model.

3---choke valve 4---counterbalance valve
5---safety protective valve 6---stop valve
7---hydraulic drive motor 8---hole for back flow
9---inlet opening
Below in conjunction with Fig. 1 working condition of the present utility model is described.
The emulsion that the utility model proposes bores the control valve group and comprises switch valve (1), safety protective valve (5) counterbalance valve (4) and the speed governing unit that is composed in parallel by overflow valve (2) and choke valve (3).The stop valve (6) of emulsion through linking to each other with coal-face master woven hose enters the control valve group.Switch valve (1) plays the start and stop effect that emulsion bores.Counterbalance valve (4) is in order to improve the duty of CD-ROM drive motor (7).Safety protective valve (5) plays the protection hydraulic system.The speed governing unit of being made up of overflow valve (2) and choke valve (3) works to regulate CD-ROM drive motor (7) output speed.Adjust the pressure reduction that choke valve (3) can change overflow valve (2) two ends control liquid, thereby adjusted the flow that returns liquid through overflow valve (2), just adjusted the flow that enters CD-ROM drive motor (7) through choke valve (3).Owing to adopted overflow, throttle grverning principle, so the control valve group both had been applicable to the needs of all kinds of emulsion power pack hydraulic systems, also can make CD-ROM drive motor reach a stable output speed when live load changes, the rotating speed adjusting range is that per minute 300～600 changes.
Below in conjunction with Fig. 2 design feature of the present utility model is described.
Consider from installation and actual use that emulsion bores, must make optimum design, make it to satisfy the design of Hydraulic System requirement, can satisfy little, the lightweight requirement of volume again the structure of control valve group.The utility model has adopted the mode of broad ways symmetric arrangement hole for back flow (8) with inlet opening (9), two hole centre distances are 40mm, so just can be directly link to each other with the advancing of CD-ROM drive motor (7), liquid return hole, adopted the arrangement of horizontal arrangement switch valve (1), overflow valve (2) choke valve (3) in width is the 95mm scope, the interior overlapping pipeline of valve body is minimized, also just reduced the height of control valve group; Adopted horizontal arrangement counterbalance valve (4) on hole for back flow (8) the center line vertical direction and on inlet opening (9) center line vertical direction the arrangement of horizontal arrangement safety protective valve (5); can make the valve body interior conduit the shortest like this, two valve center to center distance are 40mm.Control valve group appearance and size length * wide * height is 115mm * 95mm * 30mm.
The oil water emulsion drill control valve group that the utility model proposes makes coal-face can be applicable to emulsion power pack in any coal-face with oil water emulsion drill. Utilize the control valve group can regulate output speed and the torque of oil water emulsion drill, on any main infusion pipeline of coal-face, directly use emulsion by joint. It is little, in light weight that the oil water emulsion drill control valve group that the utility model proposes also has a volume, makes the weight of whole oil water emulsion drill be reduced to 10.5kg, and the weight of general electric coal drill is 15kg, and the weight of the supporting oil water emulsion drill of BJD company is 12.6kg.
