Abstract
The utility model provides a filling station oil storage equipment separation explosion-proof relief valve, includes the straight tube, and the straight tube top spiral shell closes has the pressure release base, is equipped with the rupture disk between pressure release base bottom and the straight tube top, is equipped with the fusible alloy plunger in the pressure release base, and the pressure release base spiral shell closes has blow-off pipe coupling nut, blow-off pipe coupling nut upper portion and blow-off pipe swing joint, and the blow-off pipe top is equipped with the rain cap, and the blow-off pipe lateral part is equipped with the blow-off hole. The fusible alloy plunger of the utility model is melted by the fusible alloy, so that the gas of the container is discharged from the hole originally filled with the fusible alloy to release the pressure. Mainly for preventing the container from being overpressurized due to a temperature increase, thus avoiding an explosion. The utility model discloses well rupture disk sealing performance is good, the pressure release reaction is fast and the filth that contains in the gas is less to its influence.
Description
Technical Field
The utility model belongs to the technical field of the relief valve technique and specifically relates to an explosion-proof relief valve of filling station's oil storage equipment separation.
Background
Common fracture-type safety pressure relief devices are rupture disks and rupture caps. The former is used for medium and low pressure vessels and the latter is used for high pressure and overpressure vessels. Its advantages are high sealing performance, quick release and reaction, and less influence of dirt in gas.
However, since it cannot be used continuously after the pressure release is completed and the operation of the container is stopped, it is required to be replaced with new one, and the container cannot be continuously operated and frequently replaced, which increases the cost and is frequently operated. Rupture-type safety pressure relief devices are generally only used on containers where overpressure may be small and where valve-type pressure relief devices are not easily installed.
The melting type pressure relief device is a common fusible plug. The gas in the container is discharged from the hole originally filled with the fusible alloy to release the pressure by melting the fusible alloy.
A combination pressure relief device is one that has both a matrix and a rupture type or both a matrix and a melt type. A combination of a spring safety valve and a rupture disk is common.
It has the advantages of valve type and fracture type, not only can prevent leakage of valve type safety pressure relief device, but also can make container continuously operate after discharging over-high pressure. When the container is over-pressurized, the rupture disk is broken, the safety valve is opened to exhaust, and when the pressure is reduced to normal pressure, the safety valve closes the container to continue to operate.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide an explosion-proof relief valve of filling station's oil storage equipment separation to solve the problem that proposes in the above-mentioned background art.
The utility model adopts the technical proposal that: the utility model provides a filling station oil storage equipment separation explosion-proof relief valve, includes the straight tube, and the straight tube top spiral shell closes has the pressure release base, is equipped with the rupture disk between pressure release base bottom and the straight tube top, is equipped with the fusible alloy plunger in the pressure release base, and the pressure release base spiral shell closes has blow-down pipe coupling nut, blow-down pipe coupling nut upper portion and blow-down pipe swing joint, and the blow-down pipe lateral part is equipped with the blow-down hole.
Preferably, the fusible alloy plug is a columnar body.
Preferably, a rain-proof cap is arranged at the top of the emptying pipe.
Preferably, the diameter of the rain cap is 5-6 times larger than that of the emptying pipe
Preferably, the direct pipe is fixedly connected to the fuel storage device of the gas station.
The utility model discloses well fusible alloy plunger is through the melting of fusible alloy, and the gas that makes the container is got rid of and is released pressure in the hole that originally packs with fusible alloy. Mainly for preventing the container from being overpressurized due to a temperature increase, thus avoiding an explosion. The utility model discloses in the filth that contains is less to its influence in rupture disk sealing performance is good, the pressure release reaction is fast and gas.

Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
As shown in figure 1, the blocking explosion-proof pressure release valve for the oil storage equipment of the gas station comprises a straight pipe 55, wherein the top of the straight pipe 55 is screwed with a pressure release base 53, a rupture disc is arranged between the bottom of the pressure release base 53 and the top of the straight pipe 55, a fusible alloy plunger is arranged in the pressure release base 53, a vent pipe connecting nut 52 is screwed outside the pressure release base 53, the upper part of the vent pipe connecting nut 52 is movably connected with a vent pipe 58, a rain blocking cap 59 is arranged at the top of the vent pipe 58, and a vent hole 51 is arranged at the side part of the vent pipe 58.
The fusible alloy plunger is used for discharging gas in the container from the hole originally filled with the fusible alloy through the melting of the fusible alloy so as to release pressure. Mainly for preventing overpressure of the container due to temperature rise, thereby avoiding explosion
The rupture disk has good sealing performance, quick pressure relief reaction and small influence of dirt contained in gas on the rupture disk.
It is obvious to a person skilled in the art that the invention is not restricted to details of the above-described exemplary embodiments, but that it can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. The present embodiments are, therefore, to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description.
