Description
Technical field
The utility model relates to a kind of storage tank valve body, particularly a kind of inhalation valve.
Background technique
Storage tank is used to the container storing high-pressure medium.Its medium stored is too much, the situation that pressure is excessive, can produce the situation of storage tank explosion, blast.
In pressure release, when tank inner pressure reduces rapidly, when external pressure is greater than tank inner pressure, the situation of can produce storage tank extrusion-deformation, break, exploding.
There is above situation, mainly not good integrative safety device, prevent above unexpected generation.
Model utility content
Technical problem to be solved in the utility model is for the deficiencies in the prior art, provides a kind of inhalation valve.
To achieve these goals, the measure taked of the utility model:
A kind of inhalation valve, comprise the valve casing of up/down perforation, Sealing fitting seat is provided with in valve casing, the sidewall of valve casing offers some areoles, upper sealing panel is arranged with in described valve casing, the centre of upper sealing panel offers through hole, upper sealing panel offers some inlet holes, the bottom of upper sealing panel is provided with seal base, seal base is provided with vertical pull bar, vertical pull bar is through the through hole in the middle of upper sealing panel, the top of vertical pull bar is provided with catch, the outer cover of vertical pull bar is provided with inner spring, the two ends of inner spring withstand on catch and upper sealing panel respectively, the top of valve casing has been threaded connection upper cover, outer spring is provided with between upper cover and upper sealing panel,
The bottom of the valve casing of described up/down perforation is provided with outwardly directed flange;
The bottom adhe of described upper sealing panel has sealing gasket;
The centre of described upper cover offers polygonal cap bore;
The entirety that described seal base and vertical pull bar are formed in one.
The beneficial effects of the utility model: practical, structure is simple, and cost of production is low, easy to use, safe, effectively prevents the explosion of storage tank.

Fig. 3, of the present utility modelly looks up external structure schematic diagram.
Embodiment
A kind of inhalation valve, comprise the valve casing 3 of up/down perforation, Sealing fitting seat is provided with in valve casing 3, the sidewall of valve casing 3 offers some areoles 2, upper sealing panel 6 is arranged with in described valve casing 3, the centre of upper sealing panel 6 offers through hole, upper sealing panel 6 offers some inlet holes, the bottom of upper sealing panel 6 is provided with seal base 4, seal base 4 is provided with vertical pull bar 11, vertical pull bar 11 is through the through hole in the middle of upper sealing panel 6, the top of vertical pull bar 11 is provided with catch 7, the outer cover of vertical pull bar 11 is provided with inner spring 10, the two ends of inner spring 10 withstand on catch 7 and upper sealing panel 6 respectively, the top of valve casing 3 has been threaded connection upper cover 9, outer spring 8 is provided with between upper cover 9 and upper sealing panel 6.
When without external force, the elastic force of inner spring 10, is pressed on the bottom of upper sealing panel 6 by seal base 4, realize the sealing to the enterprising pore of upper sealing panel 6; The elastic force of outer spring 8, is pressed on upper sealing panel 6 on the Sealing fitting seat in valve casing 3, realizes the upper-lower seal of valve casing 3 inside.
Storage tank is installed and the utility model, and when the pressure difference inside and outside storage tank reaches setting value of the present utility model, the utility model can start, air inlet in storage tank, or in outside exhaust, the pressure difference inside and outside maintenance, within the scope of safety value.
When the pressure in storage tank is less than outside pressure, and pressure difference is when being greater than setting value, namely to air-breathing in storage tank: medium (gas) enters in valve casing 3 by areole 2, outside pressure is excessive, this pressure overcomes the elastic force of inner spring 10, backs down seal base 4, and medium (gas) is through the inlet hole on upper sealing panel 6, enter in tank body by bottom valve casing 3, to increase the pressure in tank body.
When the pressure in storage tank is greater than outside pressure, and pressure difference is when being greater than setting value, namely storage tank is outwards exhaled: tank internal pressure is excessive, this pressure overcomes the elastic force of outer spring 8, upper sealing panel 6 is upwards backed down a distance, medium (gas) in storage tank can enter in valve casing 3 by bottom valve casing 3, and is discharged by areole 2, to reduce the pressure in storage tank.
Effectively ensure that pressure difference inside and outside storage tank is within the scope of safety value.
The bottom of the valve casing 3 of described up/down perforation is provided with outwardly directed flange 1, and the bottom of flange 1 offers seal groove 13.
The bottom adhe of described upper sealing panel 6 has sealing gasket 5, good seal performance.
The centre of described upper cover 9 offers polygonal cap bore 12, and Wrench is inserted in polygonal cap bore 12, is convenient to rotate upper cover 9 by polygonal cap bore 12.
The entirety that described seal base 4 is formed in one with vertical pull bar 11.
