Abstract
The utility model discloses a kind of pressure reducing valves, including a valve body, it is provided with for valve body to be locked at the locking device on gas cylinder on valve body, circumferential card slot is provided on the gas nozzle of gas cylinder, locking device includes being movably arranged on more than two locking members on valve body, and the position that each locking member can be different in the insertion card slot of part is moved axially with limiting valve body relative to gas cylinder.After each locking member is inserted into card slot, locking member can be abutted against with the side wall of slot and be moved axially with limiting valve body relative to gas cylinder, due to locking member quantity for two and more than, each locking member is inserted in position different in card slot, therefore, each locking member can bear the pressure of combustion gas in different positions, make the junction stress of gas cylinder and valve body evenly, avoid junction unbalance stress and lead to gas leakage.
Description
Technical field
The utility model is related to gas valve technical field, particularly a kind of pressure reducing valve.
Background technology
Pressure reducing valve be it is a kind of for reducing with the important gas-fired equipment of output pressure of stablizing combustion gas, have it is simple in structure,
Pressure stability, it is light-weight, adjust it is easy for installation the advantages that.Gas cylinder is a kind of for storing the device of high-pressure gas, pressure reducing valve one
As be mounted on gas cylinder gas outlet at, be fixedly connected by following structure with gas cylinder：It is set on the lateral wall of the gas nozzle of gas cylinder
There is a circumferential card slot, corresponding position setting, will by the cooperation of the hook and card slot there are one the hook of elasticity on pressure reducing valve
Pressure reducing valve is locked.However, in the pressure reducing valve occurred currently on the market, there are one the quantity of hook, the company of pressure reducing valve and gas cylinder
Place's unbalance stress is connect, the situation that gas valve lows while height is will appear during use, is easy to cause gas leakage.
Utility model content
In view of this, the purpose of this utility model is to provide a kind of connection that can be firm with gas cylinder, uniform forces, no
The pressure reducing valve of easy gas leakage.
The utility model for solve its technical problem and the technical solution adopted is that：
A kind of pressure reducing valve including a valve body, is provided with the locking dress for being locked at valve body on gas cylinder on the valve body
Put, be provided with circumferential card slot on the gas nozzle of the gas cylinder, the locking device include being movably arranged on two on valve body with
On locking member, the position that each locking member can be different in the insertion card slot of part is with limiting valve body relative to gas cylinder axial direction
It is mobile.
Preferably, each locking member is evenly distributed with along the circumferential direction of the gas nozzle.
Preferably, the locking member is the hook for the elasticity being arranged on valve body.
Preferably, being provided with the inlet suction port of tubulose on the valve body, the inlet suction port can be inserted into the gas nozzle
So that valve body is connected with gas cylinder in endoporus, be arranged in the air inlet pipe for close the inlet suction port and the gas nozzle it
Between gap sealing ring.
Preferably, the sealing ring of rubber by being made.
The beneficial effects of the utility model are：In the utility model, after each locking member is inserted into card slot, locking member can be with
The side wall of slot is abutted against to be moved axially with limiting valve body relative to gas cylinder, due to locking member quantity for two and more than, it is each to lock
Tight part is inserted in position different in card slot, and therefore, each locking member can bear the pressure of combustion gas in different positions, make gas
The junction stress of bottle and valve body evenly, avoids junction unbalance stress and leads to gas leakage.
Description of the drawings
The utility model is described in further detail with reference to the accompanying drawings and detailed description.
Fig. 1 is the internal structure schematic diagram of the utility model；
Fig. 2 is the partial enlarged view of part A in Fig. 1；
Fig. 3 is the structure diagram for the gas nozzle being adapted with the utility model.
Specific embodiment
Referring to figs. 1 to Fig. 3, a kind of pressure reducing valve including a valve body 1, is provided with valve body 1 being locked at gas on valve body 1
Locking device on bottle, circumferential card slot 21 is provided on the gas nozzle 2 of gas cylinder, and locking device includes being movably arranged on valve body 1
More than two locking members 11, each locking member 11 can part be inserted into card slot 21 different position with 1 phase of limiting valve body
Gas cylinder is moved axially.After each locking member 11 is inserted into card slot 21, locking member 11 can abut against to limit with the side wall of slot
Valve body 1 is moved axially relative to gas cylinder, due to locking member 11 quantity for two and more than, each locking member 11 is inserted in card slot
Different position in 21, therefore, each locking member 11 can bear the pressure of combustion gas in different positions, make gas cylinder and valve body 1
Junction stress evenly, avoids junction unbalance stress and leads to gas leakage.In order to make to bear pressure more on each locking member 11
Add uniformly, each locking member 11 is evenly distributed with along the circumferential direction of gas nozzle 2.
In the present embodiment, locking member 11 is the hook for the elasticity being arranged on valve body 1.In addition, locking member 11 can also be adopted
The device being applicable in bolt, holding screw etc..
With reference to Fig. 2 and Fig. 3, currently on the market in common gas cylinder, gas nozzle 2 have with an endoporus, which is gas cylinder
Gas outlet, be provided with a step in the endoporus of gas nozzle 2, a rubber pad 22 be provided on the step.In the present embodiment, valve body 1
On be provided with the inlet suction port 12 of tubulose, after inlet suction port 12 is inserted in the endoporus of gas nozzle 2, the end face of inlet suction port 12 is supported
It is pressed on rubber pad 22, valve body 1 can be made to be connected with gas cylinder by the sealing function of the rubber pad 22.Gas cylinder use it is long, should
Rubber pad 22 can be worn and gradually lose sealing function, in order to increase the service life of gas cylinder, be arranged in air inlet pipe useful
The sealing ring 13 in the gap between closing inlet suction port 12 and gas nozzle 2, after valve body 1 is mounted on gas cylinder, inlet suction port 12
End face is pressed on the rubber pad 22 that gas cylinder carries to form sealing, and the end face of gas nozzle 2 is then pressed on above-mentioned sealing ring 13
To form another road sealing, sealing effect is enhanced.It, still can be by upper when the rubber pad 22 carried on gas cylinder is worn
The sealing ring 13 stated forms sealing, increases the service life of gas cylinder.In the present embodiment, sealing ring 13 of rubber by being made.
The preferred embodiments of the utility model are these are only, as long as realizing the utility model aim with essentially identical means
Technical solution belong within the scope of protection of the utility model.
