Description

The electrichydraulic control spray valve
Technical field
The utility model relates to a kind of spray valve that uses in the performing comprehensive coal mining working surface automation dust suppression device under coal mine, belong to the atomising device technical field.
Background technique
During the performing comprehensive coal mining working surface production, can produce a large amount of harmful coal dusts under the coal mine,, atomizing de-dusting apparatus must be set in order to improve operating environment.Owing to also do not adapt to down-hole rugged environment and computer-controlled low voltage easy to use, the automatically controlled spray valve of little electric current at present, can only utilize the own atomizing de-dusting of coal winning machine (have also be provided with hand spray valve) in the China's coal-mine working face coal mining process, and do not have to spray at random between frame, more can not realize the automated spray depositing dust, its dust-laying effect is extremely undesirable.Therefore, designing the automatically controlled spray valve of a kind of down-hole dedicated high performance, so that improve the coal-face operating environment better, eliminate the downhole production potential safety hazard, is the problem that the relevant technologies personnel face.
Summary of the invention
The purpose of this utility model is to provide a kind of can adapt to down-hole rugged environment and computer-controlled electrichydraulic control spray valve easy to use.
The alleged purpose of the utility model realizes with following technical proposals:
A kind of electrichydraulic control spray valve, comprise operating valve, pilot valve, throttling axle and electromagnet in the formation, described operating valve is made of valve body and piston, described piston is positioned at the piston cavity of valve inner, described piston cavity side is provided with liquid entering hole, the piston upper chamber end setting-in pilot valve that it is divided into by piston, piston cavity of resorption end connects liquid outlet rapid pipe joint; Described pilot valve is a two position three-way valve, and an one interface is communicated with piston upper chamber, and two other interface is connected with liquid entering hole with liquid outlet by the water channel in the valve body wall respectively; Described electromagnet is installed on the valve body, and its armature is by the valve rod of lever control pilot valve; Described throttling axle is installed between liquid entering hole and the piston upper chamber.
Above-mentioned electrichydraulic control spray valve is provided with piston reset spring in the described piston upper chamber.
The utility model utilizes the magnet control pilot valve, with the piston position of pilot valve and throttling axle Control work valve, makes operating valve open or close.When pilot valve was closed, not connected between its three interfaces, liquid entering hole hydraulic pressure entered piston upper chamber through the throttling axle, promotes piston with piston reset spring and moves to the liquid outlet direction, made it the liquid entering hole of piston cavity side is blocked, and operating valve is closed; When pilot valve is opened, its three interfaces all communicate, liquid entering hole liquid flows to water outlet through pilot valve, and piston upper chamber communicates with water channel simultaneously, according to fluid mechanics principle, the piston upper chamber internal pressure is greater than fluid pressure in the water channel, intracavity liquid flows to water channel, and pressure descends, when piston upper chamber pressure during less than cavity pressure down, its Returnning spring of Piston Compression, operating valve is closed.
This device is power-assisted with hydraulic pressure, adopt of the opening and closing of the electromagnet of low voltage, little electric current with regard to the may command operating valve, because it is very convenient that electromagnet with switching signal control, is connected with industrial computer, for realization automated spray depositing dust has been created convenience.Compare with traditional spray valve, this device robot control system(RCS) is simple, and driving power is little, and corresponding speed is fast, is easy to installation and maintenance, is particularly suitable for using on the performing comprehensive coal mining working surface hydraulic support under coal mine.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is a sectional view of the present utility model;
Fig. 2 is the sectional view of pilot valve.
Each symbol is among the figure: 1, liquid entering hole built-up joint; 2, valve body; 3, fixed cover; 4, piston; 5, rapid pipe joint; 6, piston cavity of resorption; 7, sealing seat; 8, hand switch; 9, O-ring seals; 10, piston reset spring; 11, water channel; 12, electromagnet; 13, lever; 14, rotating shaft; 15, pilot valve; 16, piston upper chamber; 17, throttling axle; 18, pilot valve latter end; 19, steel ball Returnning spring; 20, spring seat; 21, steel ball; 22, middle push rod; 23, O-ring seals; 24, pilot valve stage casing; 25, O-ring seals; 26, O-ring seals; 27, pilot valve overcoat; 28, distance cover; 29, O-ring seals; 30, pilot valve leading portion; 31, valve rod; O, P, Q, R, S, interface.
Embodiment
The utility model has mainly improved the structural type of the dirt valve actuating mechanism that goes out, this device and process control machine are formed the coal dust system of catching that pounces on automatically, can be in coal winning machine walking coal cutting, automatically perform order, carry out spraying firing dust within the specific limits, the coal dust that produces during to coal mining forms powerful enclosing and pounces on.By detecting, coal dust system depositing dust efficient reaches more than 80% automatically, has ensured the safety in production of working surface, and the dirt effect of going out is obvious.
Referring to Fig. 1, electro-hydraulic control valve mainly is made up of two valves, a two position two-way valve of forming by valve body 2 and piston 4, another is a pilot valve 15, and the two constitutes one is the two position two-way valve of function with pilot valve 15, when electro-hydraulic control valve in a state of nature the time, liquid entering hole (working hole) P liquid enters the piston valve epicoele by throttling axle 17 slits, rely on piston reset spring, fluid pressure that piston is moved, operating valve is closed, liquid can not flow.When electromagnet 12 or hand switch 8 actions, by lever 13 transmission power is amplified, pilot valve 15 is opened, liquid entering hole P liquid flows into piston cavity of resorption 6 through throttling axle 17, pilot valve, this moment, piston upper chamber 16 pressure trend 0, and piston cavity of resorption 6 pressure are during greater than piston upper chamber 16 pressure, and operating valve begins action, liquid flows into 0 mouthful by the P mouth, and operating valve just is in open mode.Get back to the home position when electromagnet 12 or hand switch 8, pilot valve 15 is closed, and liquid stops to flow, and piston upper chamber 16 internal pressures rise, and operating valve just is in closed condition.
Referring to Fig. 2, pilot valve mainly is made up of pilot valve overcoat 27, pilot valve stage casing 24, pilot valve latter end 18, steel ball 21, steel ball Returnning spring 19, spring seat 20, valve rod 31, middle push rod 22, distance cover 28, pilot valve leading portion 30, and they constitute the two position three-way valve with three interface Q, S, R.When valve rod 31 and middle push rod 22 were in the home position, three interfaces were not connected; After valve rod 31 and middle push rod 22 moved right, the Q mouth was communicated with the R mouth, and steel ball 21 moves right simultaneously, the S mouth is communicated with, so three interfaces all communicate with the R mouth.
