Abstract
The utility model relates to an improved coal sample tank, which comprises a tank body and a tank cover; the tank body and the tank cover are provided with a corrugated metal gasket and a rubber gasket, coarse corrugations at the upper end of the corrugated metal gasket are mutually occluded with the coarse corrugations in the tank cover, and fine corrugations are adopted at the lower end of the corrugated metal gasket. The utility model discloses because cover and gas production mouth separately establish, reduced cover and jar body interface leak path, reduced the sealed degree of difficulty, need not screw up vigorously and can reach sealed effect. The protection rubber gasket and the ripple insection metal gasket that increase have effectively reduced the wearing and tearing that use repeatedly to jar body and cover, and the gas tightness increases with life. The anti-blocking device is arranged in the gas production valve, and can be automatically opened or closed under the action of gravity, so that the water-slag mixture is effectively prevented from blocking an air inlet of the gas production valve. The utility model discloses a simple structure, long service life, it is sealed effectual.
Description
[technical field]
The utility model relates to coal sample tank technical field, specifically, is a kind of modified coal sample tank.
[background technology]
In gas bearing capacity mensuration process, coal sample tank is indispensable instrument.The gas production mouth of coal sample tank is installed on cover, causes the sealing difficulty of coal sample tank to increase, when causing cover to be tightened require great effort, pad is easy to wear, tank body and cover yielding, repeatedly use after, gas easily forms boundary leakage.
In addition, coal sample tank is on the market aculeus type or valve-type now.The former in use when pricker is through rubber sheet gasket, easily blocks syringe needle or damages; And the latter is when adopting valve, valve air intake opening is easily blocked by grain slag potpourri too.
[utility model content]
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of modified coal sample tank.
The purpose of this utility model is achieved through the following technical solutions:
A kind of modified coal sample tank, it comprises tank body 1 and cover 5; It is characterized in that, be provided with ripple groove metallic gasket and rubber sheet gasket between described tank body and cover, the bastard line of ripple groove metallic gasket upper end is engaged mutually with the bastard line in cover, and ripple groove metallic gasket lower end adopts insertion waves.
With ring-shaped rubber O-ring seal on described tank body tank mouth, on the insertion waves tank mouth of direct gland tank body; The wearing and tearing at the tank mouth place of protection tank body.
The outside of tank body is provided with valve and connects valve gas outlet, and inner side is provided with valve air intake opening, and valve air intake opening adopts the anti-clogging cover that is threaded.
Described anti-clogging cover is provided with I-shaped anti-blocking plug valve, and I-shaped anti-blocking plug valve lower plate is groove.
Compared with prior art, good effect of the present utility model is:
The tank mouth of tank body increases ring seal rubber sheet gasket, increases impermeability, also avoid the wearing and tearing of tank mouth.And a ripple groove metallic gasket is increased in cover, produce relative displacement when preventing cover from tightening and between rubber sheet gasket, the wearing and tearing of rubber sheet gasket can be effectively reduced.
Valve air intake opening place arranges an anti-clogging cover, anti-clogging cover is provided with the anti-blocking plug valve of mobilizable I shape.When coal sample tank is erect, the anti-plug valve of I shape seals anti-clogging cover air intake opening automatically due to Action of Gravity Field, and prevent blocking, after installing coal sample, handstand coal sample tank, the anti-plug valve of I shape moves under gravity, opens anti-clogging cover air intake opening, can carry out desorption of mash gas.
Because cover and gas production mouth are separately set up, decrease cover and tank body boundary leakage passage, reduce sealing difficulty, do not need to tighten energetically and can reach sealing effectiveness.The protection rubber sheet gasket increased and ripple groove metallic gasket effectively reduce the wearing and tearing of Reusability to tank body and cover, and impermeability and serviceable life increase.Gas production valve internal is provided with preventing clogging up device, automatically can open or close preventing clogging up device under gravity, effectively prevents grain slag potpourri from producing blocking to gas production valve air intake opening.This utility model structure is simple, long service life, good sealing effect.
[accompanying drawing explanation]
Fig. 1 is a kind of Novel coal sample tank sectional view;
Label in accompanying drawing is respectively: 1-tank body; 2-ring-shaped rubber O-ring seal; 3-round rubber O-ring seal; 4-ripple groove metallic gasket; 5-cover; 6-anti-clogging cover; The I-shaped anti-blocking plug valve of 7-; 8-valve air intake opening; 9-valve gas outlet; 10-valve.
[embodiment]
The embodiment of a kind of modified coal sample of the utility model tank is below provided.
Embodiment 1
As shown in Figure 1, the utility model coal sample tank, includes tank body 1 and cover 5, and tank body 1 is used for holding coal sample; Ripple groove metallic gasket 4 and rubber sheet gasket 3 is provided with between described tank body 1 and cover 5, the bastard line of ripple groove metallic gasket 4 upper end is engaged mutually with the bastard line in cover 5, friction is reduced when being beneficial to rotation, ripple groove metallic gasket 4 lower end adopts insertion waves, can friction factor be increased when contacting with rubber sheet gasket 3, reduce relative displacement friction when rotating; With ring-shaped rubber O-ring seal 2 on tank body 1 tank mouth, on the insertion waves tank mouth of direct gland tank body, the wearing and tearing at the tank mouth place of protection tank body 1.Be provided with valve 10 outside the other end of tank body 1 and connect valve gas outlet 9, inner side is provided with valve air intake opening 8, and valve air intake opening 8 adopts the anti-clogging cover 6 that is threaded, anti-clogging cover 6 is provided with I-shaped anti-blocking plug valve 7, I-shaped anti-blocking plug valve 7 lower plate is groove, is convenient to gas circulation.
Principle of work: when gas bearing capacity desorb is carried out at scene, open cover 5, valve-off 10, erect tank body 1, I-shaped anti-blocking plug valve 7 seals the air intake opening of anti-clogging cover 6 under gravity, then coal sample is put into, after tightening cover 5, then the tank body 1 that stands upside down, I-shaped anti-blocking plug valve 7 opens the air intake opening of anti-clogging cover 6 under gravity, gas outlet 9 is connected with desorption of mash gas instrument, opens valve, can on-the-spot desorption of mash gas be carried out.
Because cover and gas production mouth are separately set up, decrease cover and tank body boundary leakage passage, reduce sealing difficulty, do not need to tighten energetically and can reach sealing effectiveness.The protection rubber sheet gasket increased and ripple groove metallic gasket effectively reduce the wearing and tearing of Reusability to tank body and cover, and impermeability and serviceable life increase.Gas production valve internal is provided with preventing clogging up device, automatically can open or close preventing clogging up device under gravity, effectively prevents grain slag potpourri from producing blocking to gas production valve air intake opening.This utility model structure is simple, long service life, good sealing effect.
The above is only preferred implementation of the present utility model; it should be pointed out that for those skilled in the art, without departing from the concept of the premise utility; can also make some improvements and modifications, these improvements and modifications also should be considered as in protection domain of the present utility model.
