Description
Technical field
It the utility model is related to gas cylinder valve tamper technical field, more particularly to a kind of valve antiwithdrawal device.
Background technology
Liquefied gas occupies the very big market share as clean fuel, in China, but high pressure due to liquefied gas and easily
Combustion property, the also safe handling for liquefied gas bring hidden danger, and angle valve or straight valve are to connect the important component on liquefied gas bottle, a lot
Potential safety hazard is exactly to dismantle without authorization caused by valve (angle valve or straight valve).In order to prevent that angle valve or straight valve from illegally being torn open without authorization
Unload, many manufacturers of the production with the restricted valve filled connect anti-disassembling mechanism to realize often through in angle valve or straight valve bottom
Tamper purpose.
Existing anti-disassembling mechanism, which generally comprises, easily melts temperature-sensitive axle or block that metal is made, when needing to dismantle valve, only
The thermals source such as high-temperature steam or hot water need to be used to melt temperature-sensitive axle or block, you can anti-disassembling mechanism is failed；Or will be entirely with valve
The gas cylinder of door is put into hot water, and bulk temperature can also raise, and so easily melting metal can also melt and cause anti-disassembling mechanism to fail；I.e.
Make the restricted inflating machine structure of the valve band, a small amount of high-temperature steam or hot water are still had when pouring into hot water or steam from valve port and is let out
Drain at anti-disassembling mechanism, in the presence of heat transfer gradually rise still temperature at anti-disassembling mechanism, ultimately result in temperature-sensitive axle or
Block melts and causes anti-disassembling mechanism failure, it is seen that its security is poor, in addition, easily melting metal melt in such anti-disassembling mechanism
After cannot reuse.
Utility model content
The purpose of this utility model is to provide a kind of valve antiwithdrawal device, it is intended to solves in the prior art, valve tamper
Mechanism makes the problem of easily heated thawing of temperature-sensitive axle or block causes tamper to be failed using metal is easily melted.
The utility model embodiment provides a kind of valve antiwithdrawal device, including has the tamper set of escape groove in side wall
Cylinder, the tamper sleeve is interior to have the runner for being available for fluid to circulate, and being provided with the escape groove can be to the spacing tamper of valve
Position-limit mechanism, the opening with the flow passage is offered on the madial wall of the escape groove；The position-limit mechanism includes the inner
Can lateral rotation be arranged at the block that in the escape groove and outer end is stretched out, being convexly equipped with the side wall of described block the inner can be by fluid
Promote so that the block rotates the blade group retracted in the escape groove.
Further, the blade group is included in the inner side wall of the block along the more of its circumferential uniform intervals distribution
Individual blade.
Further, the position-limit mechanism also includes being arranged at bearing pin and torsion spring in the escape groove, in the block
End is rotatably sheathed on the bearing pin, and the torsion spring set is on the bearing pin and both ends abut the avoidance groove sidewall respectively
With block inner side.
Further, axial direction of the length direction of the bearing pin parallel to the tamper sleeve.
Further, positioning hole is offered in the side wall of the escape groove side, one end of the torsion spring is inserted in described
Positioning is formed in positioning hole.
Further, the other end of the torsion spring has vertically been bent to form abutting part, and the abutting part is connected to the gear
On the madial wall of block.
Further, in the tamper sleeve radially, the width of the escape groove is more than or equal to the block
Breadth Maximum；And in the axial direction of the tamper sleeve, the height of the escape groove is more than the height of the block.
Further, the top of the tamper sleeve has along its axially extending connection end, and the connection end is used to connect
Connect the valve bottom.
Preferably, the valve is angle valve or straight valve.
Based on above-mentioned technical proposal, compared with prior art, the valve antiwithdrawal device that the utility model embodiment proposes, lead to
Cross by its block it is inner can lateral rotation be arranged in the escape groove in tamper sleeve lateral wall, and stretch out the outer end of the block
In outside escape groove, so, when the device is connected to valve bottom and integral installation is into gas cylinder, you can pass through the outer end of block
Kept out with the innter blocking part of bottle mouth of gas cylinder and realize tamper purpose, because the device does not make the portions such as temperature-sensitive axle using the easy metal that melts
Part, therefore, be not in the problem of tamper is failed when device is heated, in this way, improving the reliability of the device, and ensure that
Its security；In addition, can be by fluid forces so that the retraction of block lateral rotation avoids by being convexly equipped with the side wall of block the inner
Blade group in groove so that when needing to dismantle valve, first open limitation and fill mechanism, then by special air gun by compressed air
Or other fluids are injected in runner to laterally urge blade group, blade group drives block lateral rotation so that retracts block outer end
In escape groove, tamper function releases, and so can remove valve from gas cylinder, and whole valve antiwithdrawal device stands intact,
It is repeatable to utilize, it is effectively saved cost.
