Embodiment Construction

[0031] Below in conjunction with accompanying drawing, the present invention will be further described:

[0032] combine figure 1 , figure 2 , image 3 As shown, this double-trigger umbrella type oil and gas pipeline explosion-proof valve includes a valve body 1, a bracket 3, a valve stem guide rail 2, a valve stem group, an explosion-proof cover 16, a left mechanical response mechanism, a right mechanical response mechanism, a locking mechanism, a sensor The temperature action mechanism can block the combustion or shock wave in time when the oil and gas pipeline is burned or exploded at low pressure, so that the pipeline is in a closed state and other pipelines are prevented from being damaged. The valve body 1 is square, formed by buckling two halves and fastening them together. The two ends of the valve body 1 are the valve diameter, and the valve stem guide rail 2 is set between the left mechanical response mechanism and the right mechanical response mechanism. The val...

Abstract

The invention relates to a double-trigger umbrella type oil and gas pipeline explosion-proof valve, which includes a valve body, a bracket, a valve stem guide rail, a valve stem group, an explosion-proof cover, a left mechanical response mechanism, a right mechanical response mechanism, a locking mechanism, a sensor Warm action mechanism, the two ends of the valve body are the valve diameter, the valve stem guide rail is set between the left mechanical response mechanism and the right mechanical response mechanism, the valve stem guide rail is located in the valve body, the valve stem group is surrounded by the valve stem guide rail, and the valve stem group is outsourced A layer of explosion-proof cover; the left mechanical response mechanism and the right mechanical response mechanism are installed in the center of the valve diameter at both ends of the valve body through brackets. When the pipeline burns or explodes, the limiting plate at one end of the present invention is released and moves quickly in the guide rail, so that the valve stem group shrinks rapidly, so that the valve disc presents an open posture; when the limiting plate moves to the limit distance, It is locked with another limit plate through the lock block and the lock cavity, and cannot continue to move. At this time, the valve disc is close to the inner wall of the valve body, blocking flame or shock wave, and achieving the effect of flameproofing.

Description

Technical field: [0001] The invention belongs to the technical field of explosion-proof equipment, and in particular relates to a double-trigger umbrella type oil-gas pipeline explosion-proof valve. Background technique: [0002] In 2025, the mileage of long-distance oil and gas pipelines in my country is expected to reach 240,000 kilometers, and a cross-regional oil and gas pipeline network supply pattern has been formed. With the substantial increase in pipeline mileage, the problem of pipeline safety has become more and more serious. [0003] Generally speaking, long-distance oil and gas transportation pipelines must be equipped with explosion-proof valves. The explosion-proof valve is an overpressure automatic protection device. Its basic principle is that when the flow in the pipeline exceeds a certain value, the axial force of the valve core caused by the liquid flow makes it automatically cut off the oil circuit, which converts the flow signal into Pressure differen...
