Embodiment 1

[0061] Such as Figure 1~2 As shown, the cylinder valve emergency shut-off device is used to realize emergency shut-off of the valve on the high-pressure container, including the shut-off device body 1, the valve fixing component 2, the operating component 3, the transmission component 4 and the valve shut-off component 5. The device body 1 is connected to the valve fixing assembly 2 through the bracket 6. The shut-off device body 1 is detachably mounted on the bracket 6. The shut-off device body 1 includes an upper shell 11 and a lower shell 12, and the lower shell 12 is passed through an adjustment member. 9 is detachably connected to the bracket 6, and the upper shell 11 is detachably connected to the lower shell 12. In this way, the joint action of the upper casing 11 and the lower casing 12 is used to protect the transmission assembly 4. Through the connection of the adjustment member 9, it is convenient to disassemble, repair or replace it, and it is convenient to use. ...

Embodiment 2

[0080] The difference between this embodiment and Implementation 1 is that: Figure 10 As shown, the cross section of the inner side wall of the shut-off chuck 51 is a structure composed of five equiangular arc surfaces, and the cross-section of the inner side wall of the shut-off chuck 51 has a petal-shaped structure as a whole. In this way, the shut-off chuck 51 can be adapted to the installation of different valves, which expands the application range of the shut-off device and has strong versatility.

[0081]The specific implementation principle of the present invention is: in the initial state, the air source is the continuous air supply of the cylinder 421, pull the pull rod 433 upwards, and under the action of the rotating member 436, drive the limiting rod 434 to move towards the direction of the worm 443 until the limiting rod 434 Insert into the inside of the limiting hole 446 to limit the work of the worm 443 and the worm wheel 442. At the same time, the cylinder 42...

Abstract

The invention discloses a steel cylinder valve emergency shut-off device, and relates to the technical field of steel cylinder valve shut-off equipment. The steel cylinder valve emergency shut-off device includes a shut-off device body, a valve fixed assembly, an operation assembly, a transmission assembly and a valve shut-off assembly; the shut-off device body is connected with the valve fixed assembly through a bracket, the operation assembly is installed on the shut-off device body, and the transmission assembly is installed in the shut-off device body; the valve fixed assembly includes a fixing ring, a connecting screw hole and a bolt; the operation assembly includes an operation handle; the transmission assembly includes mechanical parts and pneumatic parts; and the valve shut-off assembly includes a shut-off clamping disk. According to the steel cylinder valve emergency shut-off device, the shut-off device body is provided with the transmission assembly composed of the pneumaticparts, the mechanical parts, limiting parts and movement limiting parts, so transmission is realized, the valve shut-off assembly is driven to achieve the emergency shut-off of a valve, the function that as long as long-distance gas resource is cut and the clamping disk is closed, the valve is closed immediately for emergency is achieved, and safety performance of an original valve is greatly improved.

Description

technical field [0001] The invention relates to the technical field of shut-off equipment for steel cylinder valves, more specifically, it relates to an emergency shut-off device for steel cylinder valves. Background technique [0002] A pressure vessel refers to a closed device that holds gas or liquid and carries a certain pressure. It has a wide range of uses. Among them, for metal containers suitable for liquefied petroleum gas, coal gas, methyl ether, natural gas, etc., the circulation and shutoff of high-pressure gas are not realized, and valves are usually installed on the pressure container. However, once the high-pressure gas leaks at the valve, it is easy to cause accidents such as explosion and gas poisoning, and the occurrence of abnormal phenomena such as earthquakes will also cause the above-mentioned dangerous situations. [0003] Based on the above problems, it is necessary to propose an emergency shut-off device for a high-pressure vessel that can realize e...
