Description
Technical Field
The utility model relates to the technical field of valves, especially, relate to a valve is blocked in pneumatic fire prevention of self-fusing formula for low temperature pressure vessel.
Background
Various pneumatic valves are required to be arranged on a storage tank or a conveying pipeline of the low-temperature pressure container to control the opening and closing states of the tank body or the pipeline. Because some media have high dangerousness, once a fire occurs, if the transportation of the media cannot be cut off in time, the fire is difficult to control, explosion and the like can occur. If the medium conveying is cut off in a mode of cutting off the air source after the fire is found, on the one hand, the medium cannot be cut off in time, the fire condition can be enlarged, and on the other hand, under the condition of fire, personnel cannot approach the valve and cannot operate.
SUMMERY OF THE UTILITY MODEL
The utility model provides a solve above-mentioned problem, provide a low temperature pressure vessel is with blocking valve from pneumatic fire prevention of fusing formula.
In order to solve the technical problem, the technical scheme of the utility model is that: low temperature pressure vessel is with blocking valve from pneumatic fire prevention of fusing formula, which comprises a valve body, the link is all installed to the both sides of valve body, be provided with the valve ball in the valve body, the top of valve ball is connected with the valve rod, the valve rod is equipped with the extension sleeve outward, telescopic bottom and valve body fixed connection are prolonged, braced frame is installed on the telescopic top of extension, be located the inside connecting rod bottom of braced frame and be connected with the top of valve rod, single-action pneumatic actuator is installed at braced frame's top, single-action pneumatic actuator's cylinder body center department square groove links to each other with the connecting rod top, install fusible plug and fusible plug protection device on the single-action pneumatic actuator, single-action pneumatic actuator's gear shaft upper portion is the square structure, single-action pneumatic actuator is worn.
Further, the both sides of valve body all install the link through the bolt.
Further, the support frame is fixed to the top of the extension sleeve by bolts.
Further, the support frame is fixed to the bottom of the single-acting pneumatic actuator by bolts.
Furthermore, the single-action pneumatic actuator is connected with the air compressor through a pneumatic pipeline.
Furthermore, the fusible plug protection device is connected with the top of the single-action pneumatic actuator in a bolt distance-adjustable mode.
The utility model discloses simple structure, design benefit, it is rationally distributed, can realize after ambient temperature reaches specific scope, the automatic triggering fusible plug melts, causes the quick self-bleeding of single-action pneumatic actuator, and carminative speed is greater than the speed that the air supply admits air for single-action pneumatic actuator realizes the self-closing operation of valve in the state that air supply pressure does not cut off, and then realizes the purpose of automatic cutout medium transport in the very first time. Because of the stability of pneumatic control, the connecting rod can not generate stress concentration when rotating, the mechanism is not deformed, the accuracy of the rotating angle is ensured, and the service life of the product is ensured. After the valve is closed, the gear shaft at the upper part of the single-action pneumatic actuator can be rotated by a wrench, so that the aim of opening the valve is fulfilled. Simultaneously, the fire prevention blocks when valve because of the restriction of mounted position or inconvenient close range manual loading single-action pneumatic actuator, can use single-action pneumatic actuator's pneumatic loading function, as long as connect pneumatic pipeline, can load in the short time and open the valve. The fire-proof blocking valve is arranged on a storage tank for containing inflammable and explosive media, can be used as a first barrier for fire prevention and fire retardation, can automatically react in a very short time, reduces the output of the inflammable media as much as possible, and further contributes to controlling the fire condition when an accident occurs.
