Background technique
Rock gas is the fuel of a kind of high-quality, clean and environment-friendly, and it both can be used as civil use material, is widely used in vehicle fuel again.The natural gas used for automobile cylinder valve is the special valve of natural gas used for automobile steel cylinder, and himself also has the safety protection effect except having on-off action, namely when overpressure, can carry out pressure release.The pressure releasing of existing natural gas used for automobile cylinder valve is inaccurate usually, and may not reach just pressure release when releasing standard, or surpassing relieving pressure pressure release not yet, the former waste that causes releasing, then there is potential safety hazard in the latter.
The model utility content
First purpose of the present utility model is: a kind of safety helmet is provided, is used on the compressed gas cylinder valve, can solve the compressed gas cylinder valve pressure and discharge inaccurate technical problem.
In order to solve the problems of the technologies described above, the utility model provides a kind of embedded-type security cap, comprise cap body, low melting alloy material, low melting alloy plug and rupture disk, described low melting alloy material is near the first end setting of described cap body, second end of described cap body is offered porose, described rupture disk seals the hole that described cap body second end is offered, first end of described low melting alloy plug is connected with described low melting alloy material, second end stretches out the hole that described cap body second end is offered, and contacts with described rupture disk.
Preferably, first end of described cap body is greater than second end.
Preferably, described low melting alloy material and low melting alloy plug all can move according to variation of temperature.
Preferably, the fusing point of described low melting alloy material and low melting alloy plug is 105 ℃～115 ℃.
Preferably, the fusing point of described low melting alloy material and low melting alloy plug is 110 ℃.
Preferably, described cap body, low melting alloy material and low melting alloy plug have same axis.
Preferably, described safety helmet adopts profile cutter machining to form.
Preferably, the action of described low melting alloy plug makes when pressure reaches 27MPa～33MPa, described rupture disk stretching explosion.
Preferably, described low melting alloy plug action makes when pressure reaches 30MPa described rupture disk stretching explosion.
Another purpose of the present utility model is: the pressurized gas cylinder valve that the accurate release pressure of a kind of energy is provided.
In order to solve the problems of the technologies described above, the utility model provides a kind of pressurized gas cylinder valve, comprises valve body, and above-mentioned arbitrary described safety helmet, and first end of described cap body is connected with described valve body.
With respect to prior art, the utility model has following advantage:
1, low melting alloy material and low melting alloy plug are set in the cap body, low melting alloy material and low melting alloy plug can move according to temperature variation, make action more accurately, in time;
2, the low melting alloy plug that grinds of centerless grinding machine is directly compressed into the safety helmet body that processes, and has avoided the secondary operations cutter to run into the R face, thereby it is inaccurate to influence bursting pressure, disabler.
Description of drawings
Figure 1 shows that the utility model pressurized gas cylinder valve one embodiment's structural representation.
Embodiment
In order more to be expressly understood above-mentioned purpose of the present utility model, feature and advantage, below in conjunction with the drawings and specific embodiments the utility model is further described in detail.
A lot of details have been set forth so that fully understand the utility model during description below is concrete; but the utility model can also adopt other to be different from other modes described here and realize; therefore, protection domain of the present utility model is not subjected to the restriction of following public specific embodiment.
Need to prove that under the situation of not conflicting, the application's implementation column and the feature among the embodiment can make up mutually.
As shown in Figure 1, the utility model safety helmet adopts profile cutter machining to form, and comprises the rupture disk 4 that cap body 1, low melting alloy material 2, low melting alloy plug 3 and nickel-base alloy are made, and cap body 1, low melting alloy material 2 and low melting alloy plug 3 have same axis; First end of cap body 1 is greater than second end; Low melting alloy material 2 and low melting alloy plug 3 all can move according to variation of temperature, and fusing point is 110 ℃; Low melting alloy material 2 is near the first end setting of cap body 1, and second end of cap body 1 is offered porose, and first end of low melting alloy plug 3 is connected with low melting alloy material 2, and second end stretches out the hole that cap body 1 second end is offered.When temperature reaches 110 ℃, low melting alloy material 2 and low melting alloy plug 3 move because of distortion.The hole that rupture disk 4 sealing sealed cap bodies 1 second end is offered, the hole that low melting alloy plug 3 is offered by sealed cap body 1 second end contacts with rupture disk 4.Because low melting alloy plug 3 contacts with rupture disk 4, so the action of low melting alloy plug 3 can pass to rupture disk 4, when the action of low melting alloy plug 3 made pressure reach rupture disk 4 to be enough to the pressure of explosion, rupture disk 4 will stretch explosion with pressure release.In this implementation column, the bursting pressure of rupture disk 4 is 30MPa, and namely when the action of low melting alloy plug 3 made that pressure reaches 30MPa, rupture disk 4 stretching explosions were with pressure release.
In other implementation column, can also select fusing point as required is the low melting alloy material of different melting points such as 105 ℃, 115 ℃.
Can be chosen as according to actual needs at the bursting pressure of other implementation column borehole blasting sheets 4 and to be 27MPa, 33MPa etc.
The utility model also provides a kind of pressurized gas cylinder valve, comprises the valve body (not shown), and above-mentioned safety helmet, and first end of described cap body 1 is connected with described valve body.
Low melting alloy plug 3 moves according to the variation of temperature in the compressed gas cylinder, temperature in compressed gas cylinder makes 3 actions of low melting alloy plug acquire a certain degree, the action that is low melting alloy plug 3 makes when pressure reaches the bursting pressure of rupture disk 4 that rupture disk 4 will stretch explosion with pressure release.
The announcement of book and instruction according to the above description, the utility model those skilled in the art can also change and revise above-mentioned mode of execution.Therefore, the embodiment that discloses and describe above the utility model is not limited to also should fall in the protection domain of claim of the present utility model modifications and changes more of the present utility model.In addition, although used some specific terms in this specification, these terms do not constitute any restriction to the utility model just for convenience of description.
