Abstract
The utility model discloses a steer cylinder valve with a safety protection function and belongs to a steer cylinder valve. The steer cylinder valve with the safety protection function comprises a shell body, a sealing top rod, a first spring, a first spring seat and a clamping bolt. An inner cavity and an air inlet pipeline and an air outlet pipeline are arranged on the shell body. A first ring-shaped boss is arranged on the shell body which is located between the air outlet pipeline and the inner cavity. A guiding hole is formed on the first spring seat, wherein a circular platform is arranged on the shell body, and a decompression cavity communicated with the inner cavity is formed on the circular platform. A second ring-shaped boss is arranged on the shell body which is located between the decompression cavity and the inner cavity. A second spring, a second spring seat and a regulating bolt are arranged inside the decompression cavity. The regulating bolt is in threaded connection with the circular platform. A second through hole is formed on the regulating bolt. The second spring is headed between the regulating bolt and the second spring seat. A sealing cushion is connected at the lower end of the second spring seat. The sealing cushion is clamped on the second ring-shaped boss. The steer cylinder valve with the safety protection function has the advantages of capable of preventing the phenomenon that an explosion is caused by the too high pressure of the gas inside the pressure container and providing the function of safety and protection.
Description
Technical field:
The utility model relates to a kind of cylinder valve, specifically is a kind of cylinder valve with safety protection function that is installed on gas pressure tank or the pressure bottle.
Background technique:
We know, cylinder valve is installed on gas-tank, the oxygen cylinder equal pressure container usually, interface when inflating with air feed as pressurized container, when pressurized container during in when inflation, when depositing or in transportation, because inflation pressure is excessive, ambient temperature is too high or pressurized container when being subject to clashing into, the capital causes that the gas pressure in the pressurized container is too high and blasts, thereby affects people's the security of the lives and property.
The model utility content:
The technical problems to be solved in the utility model is that a kind of cylinder valve with safety protection function is provided.
Technical solution of the present utility model is; provide a kind of cylinder valve with safety protection function with following structure: comprise housing; the sealing push rod; the first spring; the first spring seat and housing screw; housing is provided with inner chamber and the gas-entered passageway that communicates with inner chamber and outlet passageway; housing screw is connected on the housing of inner chamber right-hand member; housing screw is provided with the first through hole; housing between outlet passageway and the inner chamber is provided with the first annular boss; the first spring seat is arranged in inner chamber; its right-hand member is pressed on the screw; the first spring seat is provided with pilot hole; sealing push rod left end withstands on the first annular boss; right-hand member is inserted in the pilot hole; the first spring is positioned at pilot hole; the left end of the first spring withstands on the sealing push rod; right-hand member withstands on the first spring seat; wherein; housing is provided with round platform; round platform is provided with the pressure-releasing chamber that communicates with inner chamber; housing between pressure-releasing chamber and the inner chamber is provided with the second annular boss; be provided with the second spring in the pressure-releasing chamber; the second spring seat and adjusting screw; adjusting screw is threaded with round platform; adjusting screw is provided with the second through hole; the second spring top is between adjusting screw and the second spring seat; the second spring seat lower end is connected with sealing gasket, and sealing gasket is pressed on the second annular boss.
After adopting above structure; compared with prior art; the cylinder valve that the utlity model has safety protection function has the following advantages: during use; an end of gas-entered passageway that the utlity model has the cylinder valve of safety protection function is connected with pressurized container and communicates; when the gas pressure in the pressurized container is too high; high pressure air is known from experience the promotion sealing gasket and the second spring seat moves upward; the second spring contraction; pressure-releasing chamber is communicated with inner chamber; gas in the pressurized container can be discharged by pressure-releasing chamber and the second through hole; after the gas in the pressurized container reduces; under the effect of the second spring power; promoting the second spring seat moves downward; sealing gasket is pressed on the second annular boss; pressure-releasing chamber and inner chamber have been cut off; by adjusting the maximum gas force value of adjusting screw in can the setting pressure container; when the gas pressure in the pressurized container during greater than setting value; section can will discharge from pressure-releasing chamber by gas; played the effect of step-down; prevented having had the function of safety protection because of the too high phenomenon of blasting of the gas pressure in the pressurized container.
Description of drawings:
Fig. 1 is that the master who the utlity model has the cylinder valve of safety protection function looks the sectional structure schematic representation.
Embodiment:
Below in conjunction with the drawings and specific embodiments the cylinder valve that the utlity model has safety protection function is described further:
