Abstract
The utility model discloses the mining multiple gases sampling thief of a kind of novel improved, it is the pump bowl that underground mine use carries out gas sampling, join with CO or O2 assessor and carry out measurement gas, this sampling thief by air intake opening, gas outlet, piston rod, machine skin, duroplasts, push away handle, housing forms.It is characterized in that: utilize machine skin and duroplasts to replace the T-valve of traditional pump bowl, it is huge that traditional pump bowl gathers gas sample workload, if it is just more difficult to get the gas sample in several places.Piston rod is moved in improved pumpback afterwards, just can realize air intake opening air inlet and give vent to anger from gas outlet, and the gas that detect is directly injected into detector tube or gas inject in bladders, simple to operate time saving and energy saving, quick collection gas.
Description
Technical field
The utility model relates to mine gas detection field, is specially the mining multiple gases sampling thief of a kind of novel improved.
Background technology
The exploitation scale in colliery is continuous in recent years must increase, and the degree of depth of exploitation continues to increase, and in coal production process, production safety problem has become one of problem of paying attention to the most in colliery.Collection gas sample judgement underground work Environmental security situation becomes and becomes an important content.Mining CGY50 type multiple gases sampling thief is the suction-pump that underground mine use carries out gas sampling, join with CO or O2 assessor and carry out measurement gas, concrete operations are: utilize after sampling thief (the injector principle of just using as hospital) extracting gases front end to have a T-valve to be stored in suction-pump gas is of short duration getting to 45 degree, again CO or O2 assessor two ends are disconnected, then insert the outlet side of pump bowl, again T-valve handle is got to the port of giving vent to anger, slowly pushing out gas is tested and appraised pipe and reads numerical value. measure the concentration value of gas.
Analyze and the basis of the gas sampler of research tradition on, adopted the mining multiple gases sampling thief of a kind of novel improved.
Utility model content
The purpose of this utility model is to provide the mining multiple gases sampling thief of a kind of novel improved, to solve existing pump bowl, cannot carry out the drawback of uninterruptedly bleeding continuously, greatly must reduce and gather gas workload.
In order to achieve the above object, the technical scheme that the utility model adopts is:
Novel improved is mining multiple gases sampling thief the T-valve on original pump bowl removing completely, at a duroplasts disk of the inner installation of pump bowl, there are 4 small sircle holes above, in the middle of disk, there is a conelet post, with machine skin, pacify to conelet post, so just be arranged on pump bowl relevant position, principle is when piston rod is moved pump bowl terminal position to, gas is from air intake opening, machine hide leaves gas and enters in pump bowl, and machine skin in gas outlet is owing to being to be negative pressure state in cylinder when bleeding, so atmospheric pressure is higher than pump bowl negative pressure above the machine skin of air intake opening, the machine skin of air intake opening is sealing state, and when piston rod is shifted pump bowl front end onto, otherwise air intake opening machine skin is closed, gas outlet machine hide is opened, twitch so back and forth piston rod, just can realize air intake opening air inlet gives vent to anger from gas outlet, the gas that will detect is directly injected into detector tube or gas inject in bladders, simple to operate time saving and energy saving, quick collection gas.
The utility model is to improve pump bowl inner structure, and its maximum feature is improved simple and convenient, substantially need not change original primary structure, can realize carrying out continuously of gas sampling, greatly must reduce workload and time.
The utility model has the advantages that: the utility model method is reliable and stable, and actual operation is strong, simple, and temperature influence is little, after improvement, greatly increases work efficiency.
Accompanying drawing explanation
Fig. 1 is the mining multiple gases sampling thief of novel improved that the utility model adopts.In figure, numeral is as follows: 1. air intake opening; 2. gas outlet; 3. piston rod; 4. machine skin; 5. duroplasts; 6. push away handle.
Embodiment
Novel improved is mining multiple gases sampling thief the T-valve on original pump bowl removing completely, at a duroplasts disk of the inner installation of pump bowl, there are 4 small sircle holes above, in the middle of disk, there is a conelet post, with machine skin, pacify to conelet post, so just be arranged on pump bowl relevant position, principle is when piston rod is moved pump bowl terminal position to, gas is from air intake opening, machine hide leaves gas and enters in pump bowl, and machine skin in gas outlet is owing to being to be negative pressure state in cylinder when bleeding, so atmospheric pressure is higher than pump bowl negative pressure above the machine skin of air intake opening, the machine skin of air intake opening is sealing state, and when piston rod is shifted pump bowl front end onto, otherwise air intake opening machine skin is closed, gas outlet machine hide is opened, twitch so back and forth piston rod, just can realize air intake opening air inlet gives vent to anger from gas outlet, the gas that will detect is directly injected into detector tube or gas inject in bladders, simple to operate time saving and energy saving, quick collection gas.
Claims (2)
1. the mining multiple gases sampling thief of novel improved, is the pump bowl that underground mine use carries out gas sampling, coordinates CO or O2 assessor to carry out measurement gas, this sampling thief by air intake opening, gas outlet, piston rod, machine skin, duroplasts, push away handle, housing forms.It is characterized in that: utilize machine skin and duroplasts to replace the T-valve of traditional pump bowl, it is huge that traditional pump bowl gathers gas sample workload, if it is just more difficult to get the gas sample in several places.Piston rod is moved in improved pumpback afterwards, just can realize air intake opening air inlet and give vent to anger from gas outlet, and the gas that detect is directly injected into detector tube or gas inject in bladders, simple to operate time saving and energy saving, can realize quick collection gas.
2. the mining multiple gases sampling thief of novel improved according to claim 1 is characterized in that: the improvement simple and convenient of this gas sampler, need not change original primary structure substantially.There is very large development space, be widely used.
