Abstract
The utility model relates to a limited-pressure inflation gun for gas drainage plugging, which can efficiently solve the problems of difficult operation, air bag damage caused by expansion and insufficient inflation. The limited-pressure inflation gun adopts the technical scheme that an air pressure source, a safety valve and a reduction valve are included, wherein the air pressure source is connected with the reduction valve through an air filter and a hose, the reduction valve is connected with a manual control valve through a hose, and the safety valve is mounted on a pipeline at the air outlet of the manual control valve. The utility model has the advantages of simple structure, novel and unique design, convenient use and installation, and good using effect, efficiently prevents bag damage caused by expansion and insufficient inflation, ensures safe use, and is an innovation in gas drainage equipment.
Description
One, technical field
The utility model relates to gas discharge in mine equipment, particularly a kind of gas drainage under suction sealing of hole pressure limiting charge gun.
Two, background technology
Gas drainage under suction is the essential safety in production problem that solves in the Coal Production, particularly along with dark increasing is adopted in the colliery, coal seam gas-bearing capacity increases gradually, the gas problem has become the key factor of restriction Safety of Coal Mine Production, gas drainage under suction is the important technical that solves the gas problem, but at present because the problem on the gas drainage under suction device structure, after gas drainage hole packer injects firedamp taking-out discharging drilling inside, its air bag position can not be seen, when giving airbag aeration, be difficult to grasp the situation of opening of air bag, often run into that air bag is risen brokenly or the under-inflation phenomenon, influenced the safety of using greatly, therefore, the improvement of its equipment and innovation are the essential technical problems that solves.
Three, utility model content
At above-mentioned situation, for overcoming the prior art defective, the purpose of the utility model just provides a kind of gas drainage under suction sealing of hole pressure limiting charge gun, can effectively solve difficult operation and air bag is risen brokenly or the problem of under-inflation phenomenon.
The technical scheme of its solution is, comprises pneumatic supply, safety valve and reducing valve, and pneumatic supply links to each other with reducing valve with flexible pipe through air filter, and reducing valve links to each other with people's force control valve (control button formula) through flexible pipe, on the gas outlet pipeline of people's force control valve safety valve is housed.
The utility model is simple in structure, and novel unique, easy to install, result of use is good, prevents that effectively air bag from rising brokenly or the problem of under-inflation, guarantees safe handling, is the innovation on the gas drainage under suction equipment.
Four, description of drawings
Accompanying drawing is a structure chart of the present utility model.
Five, the specific embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is elaborated.
Shown in accompanying drawing, the utility model comprises pneumatic supply, safety valve and reducing valve, pneumatic supply 1 links to each other with reducing valve 4 with flexible pipe 3 through air filter 2, and reducing valve 4 links to each other with people's force control valve (control button formula) 6 through conduit, on the gas outlet pipeline of people's force control valve 6 safety valve 5 is housed.
In order to guarantee result of use, said flexible pipe and gas outlet pipeline are circle; Said flexible pipe 3 constitutes downward circular-arc; Conduit on said people's force control valve 6 imports, the outlet constitutes square that opening makes progress.
When the utility model uses, link to each other with gas drainage hole packer, when air bag reaches preset pressure, the pressure limiting charge gun just can not be inflated in the air bag of gas drainage hole packer again, avoid gasbag pressure not reach requiring or appearance that pressure is crossed the relieving stagnant Qi capsule situation that rises sharply, effectively guaranteed the safe in utilization of gas drainage hole packer and the safe handling that draws out methane.
It is to be noted; creative contribution of the present utility model is existing each parts through scientific and reasonable combining; constitute a kind of novel pressure limiting charge gun; be effective on the gas drainage hole packer; guarantee the safe handling that draws out methane; above-mentioned accompanying drawing only is the embodiment that provides, and all technical schemes that structurally adopts the equivalence techniques means to replace are the scope that the utility model is protected.
