Abstract
The utility model discloses a kind of dual fail-safe detatching-proof cylinder valve, include valve body, pressure cap, valve rod and handwheel, the valve port of the valve body is formed with first convex shoulder of circle, the cap edge of the pressure cap is connect with the first convex shoulder roll riveting, and the periphery wall of the internal perisporium of pressure cap and the first convex shoulder offers the card slot of pairing respectively, snap ring is installed in card slot, the top of the mobile jib of valve rod is formed with second convex shoulder of circle, it is equipped with the first sealing rubber ring between the top and pressure cap of second convex shoulder, and is equipped with the second sealing rubber ring between the bottom and valve port of the second convex shoulder.Prevent lawless people from illegally being dismantled to cylinder valve since the utility model uses roll riveting and this double insurance of snap ring, even if lawless people tool pries open the roll riveting cap edge of pressure cap, due to the clamping of snap ring, lawless people still can not take off pressure cap, so that detatching-proof cylinder valve has preferable anti-disassembling function, the security performance of cylinder valve is effectively promoted.
Description
Technical field
The utility model is related to the cylinder valves of valve technology field, especially steel cylinder.
Background technology
In the cylinder valve of steel cylinder, valve rod is that the mobile jib of valve rod is mounted in valve body by pressure cap, and valve rod is for driving
What movable valve plug opened and closed, pressure cap cuff valve rod, and be fixedly connected with the valve port of valve body, while installing sealing additional between pressure cap and valve port
Circle, to reach sealing effect.The pressure cap of traditional cylinder valve be usually be threadedly coupled with the valve port of valve body, this mode be easy to by
Lawless people illegally dismantles cylinder valve with conventional tool, illegally fills purpose to reach, there are great security risks.Mesh
Before, also have and the valve port of pressure cap and cylinder valve is connected using roll riveting, to achieve the purpose that Anti-dismantling.But this anti-disassembling function is
Very single, lawless people is still easy to the cap edge with tamper tool pressure cap roll riveting, and cylinder valve is dismantled.Therefore, it is necessary to right
Existing detatching-proof cylinder valve is improved, and makes it have the function of multiple Anti-dismantling, to improve security performance.
Utility model content
The technical problem to be solved by the present invention is to provide a kind of cylinder valves preventing dismounting with double insurance.
Used technical solution to solve above-mentioned technical problem：A kind of dual fail-safe detatching-proof cylinder valve includes valve body, pressure
Valve rod that cap, driving spool open and close and to twist the handwheel of valve rod, the pressure cap the mobile jib cuff of valve rod in valve body,
It is characterized in that：The valve port of the valve body is formed with first convex shoulder of circle, and the cap edge of the pressure cap is connect with the first convex shoulder roll riveting,
And the periphery wall of the internal perisporium of pressure cap and the first convex shoulder offers the card slot of pairing respectively, and snap ring is equipped in card slot, valve rod
The top of mobile jib is formed with second convex shoulder of circle, and the first sealing rubber ring, and second are equipped between the top and pressure cap of the second convex shoulder
The second sealing rubber ring is equipped between the bottom and valve port of convex shoulder.
Using advantageous effect caused by the utility model：Since the utility model uses roll riveting and snap ring this dual guarantor
Danger prevents lawless people from illegally being dismantled to cylinder valve, even if lawless people tool pries open the roll riveting cap edge of pressure cap, by
In the clamping of snap ring, lawless people still can not take off pressure cap, so that detatching-proof cylinder valve has preferable Anti-dismantling
Function effectively promotes the security performance of cylinder valve.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model dual fail-safe detatching-proof cylinder valve.
Specific implementation mode
As shown in Figure 1, a kind of dual fail-safe detatching-proof cylinder valve, includes valve body 1, pressure cap 2, the valve rod 3 for driving spool to open and close
And to twist the handwheel 4 of valve rod 3, the pressure cap 2 is 31 cuff of mobile jib of valve rod 3 in valve body 1.In the utility model
In, the valve port of the valve body 1 is formed with first convex shoulder of circle 11, and the cap of the pressure cap 2 is connect along 21 with 11 roll riveting of the first convex shoulder,
And the periphery wall of the internal perisporium of pressure cap 2 and the first convex shoulder 11 offers the card slot 5 of pairing respectively, and snap ring 6 is equipped in card slot 5,
The top of the mobile jib 31 of valve rod 3 is formed with second convex shoulder of circle 32, and it is close that first is equipped between the top and pressure cap 2 of the second convex shoulder 32
Sealing rubber ring 7, and the second sealing rubber ring 8 is equipped between the bottom and valve port of the second convex shoulder 32.
The installation of pressure cap 2 and 1 valve port of valve body uses roll riveting and snap ring this dual fixed form, prevents lawless people to bottle
The significant effect that valve is illegally dismantled, even if lawless people tool pries open the roll riveting cap edge of pressure cap, due to the card of snap ring
Tightly, lawless people still can not take off pressure cap, so that detatching-proof cylinder valve has preferable anti-disassembling function.
