Abstract
The utility model relates to a device used in a coal mine, particularly to a mine downhole undercast pneumatic throttle interlocking device, which comprises a gas path A and gas path B with the same structure. Both the gas path A and the gas path B comprises a cylinder, a two-position three-way pneumatically-controlled normally open valve, a two-position five-way control valve, locking valves, and manual switches; one end of the cylinder is connected with the two-position three-way pneumatically-controlled normally open valve via a gas pipe, the other end of the cylinder is connected with the two-position five-way control valve, and the two-position three-way pneumatically-controlled normally open valve is connected with the two-position five-way control valve; the two-position five-way control valve is connected with two locking valves, and each locking valve is connected with two manual switches; and the gas pipe of the gas path A is connected with the two-position three-way pneumatically-controlled normally open valve of the gas path B via a pipeline, and the gas pipe of the gas path B is connected with the two-position three-way pneumatically-controlled normally open valve of the gas path A. The pneumatic throttle interlocking device solvent the problems in the prior art, including inflexible shape, inconvenient installation, high cost and poor sealing property.
Description
Technical field
The utility model relates to a kind of colliery device, the damper control that use particularly a kind of mine down-hole.
Background technology
The air door of down-hole use at present comprises doorframe, door-plate and position-limit mechanism, door-plate and doorframe flexibly connect, design has position-limit mechanism to carry out spacing to door-plate on the doorframe, prevent its reverse flip, door-plate under normal circumstances is under the effect of blast closes, and when needs are opened air door, must overcome the pressure that blast produces door-plate, because the down-hole blast is bigger, cause the quite effort of opening the door.In addition, air door all is twice, for preventing to ventilate, must guarantee also when an air door is opened that another air door closes, and manually-operated is difficult to guarantee this requirement.Chinese patent ZL200520084823.3 has announced a kind of automatic control storm door, and it adopts the infrared ray sensing device, has solved the unmanageable problem of coal mine lower wind door switch.But it exist switch dumb, be not easy to install, the problem of cost height, sealing difference.
The utility model content
The purpose of this utility model provides a kind of coal mine lower air duct pneumatic air door interlock, solved the shape that existing technology exists dumb, be not easy to install, the problem of cost height, sealing difference.
Coal mine lower air duct pneumatic air door interlock of the present utility model, form by gas circuit A and gas circuit B, gas circuit A is identical with gas circuit B structure, and gas circuit A and gas circuit B are made up of cylinder, two-position three way list gas control system normally open valve, two-position five-way control valve, locking-valve and hand switch respectively; One end of cylinder connects two-position three way list gas control system normally open valve by tracheae, and the other end of cylinder connects the two-position five-way control valve, and two-position three way list gas control system normally open valve links to each other with the two-position five-way control valve; The two-position five-way control valve connects two locking-valves respectively, and each locking-valve connects two hand switches respectively; The tracheae of gas circuit A is by the two-position three way list gas control system normally open valve of pipeline connection gas circuit B, and the tracheae of gas circuit B connects the two-position three way list gas control system normally open valve of gas circuit A by pipeline.
Coal mine lower air duct pneumatic air door interlock, this device has practical, full mechanical, novel in design attractive in appearance, simple in structure, be convenient to make installation and maintenance, economy and durability, be easy to promote, need not power supply, can be because of electric equipment does not cause coal dust, the gas explosion phenomenon, action property, the advantage that good stability is easy to operate.Two cylinders connect the 1# door and the 2# door of down-hole respectively, only need to close the door under the light finger flicking just can open automatically, and the energy locking, performance is good.The 1# door is opened, and the 2# door is not just opened, and must the 1# door closes back 2# door and just can open, can not cause distinguished and admirable short circuit phenomenon like this, not influence the tunnel air feed, guarantee that air feed needs, easy for installation, instant effect can make door sealing better, good looking appearance, noiseless at closing time, no matter the blast size, switch is convenient, flexible, especially in the bigger place of blast, use and convenience.
Result of use: this device latch effect is obvious, easily adorn, handy easy-maintaining, having stopped to open simultaneously the twice air door operates against regulations, can effect a radical cure the distinguished and admirable instability of getting working face, calm, gentle breeze phenomenon can be utterly destroyed the distinguished and admirable short circuit between mainly advancing back, the real reliable interlocking of realizing between air door plays important effect to preventing gas accident.Be suitable for all kinds of mines and especially height vacated mine.This is the once technical breakthrough of air door interlock, has higher popularization and application values.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing and with illustrated embodiments the utility model is done detailed explanation.
Consult Fig. 1, coal mine lower air duct pneumatic air door interlock, be made up of gas circuit A and gas circuit B, gas circuit A is identical with gas circuit B structure, and gas circuit A and gas circuit B are made up of cylinder 1, two-position three way list gas control system normally open valve 2, two-position five-way control valve 3, locking-valve 4 and hand switch 5 respectively; One end of cylinder 1 connects two-position three way list gas control system normally open valve 2 by tracheae 6, and the other end of cylinder 1 connects two-position five-way control valve 3, and two-position three way list gas control system normally open valve 2 links to each other with two-position five-way control valve 3; Two-position five-way control valve 3 connects two locking-valves 4 respectively, and each locking-valve 4 connects two hand switches 5 respectively; The tracheae 6 of gas circuit A is by the two-position three way list gas control system normally open valve 2 of pipeline connection gas circuit B, and the tracheae 6 of gas circuit B connects the two-position three way list gas control system normally open valve 2 of gas circuit A by pipeline.
