Abstract
Description
Technical Field
[0001] The utility model relates to a pressure relief valve for fluorine-lined pipe fittings. Background Art
[0002] The pressure relief valve is generally used when storing liquid in a tank, and is usually used in conjunction with a breather valve installed on the tank top to maintain the normal pressure in the tank. It can avoid accidents caused by damage to the storage tank when the pressure in the tank suddenly exceeds the limit or forms a vacuum due to accidental reasons. However, the traditional pressure relief valve is inconvenient to use. It needs to be detected by a pressure gauge and then the pressure is released by the staff, which is rather troublesome and likely to cause the problem that the internal pressure of the tank cannot be released in time, posing a potential danger. Content of the Utility Model
[0003] The utility model improves the above problems, that is, the technical problem to be solved by the utility model is to provide a pressure relief valve for fluorine-lined pipe fittings, which is convenient to use, has a good pressure relief effect, and reduces potential safety hazards.
[0004] The utility model is composed of a pressure relief pipeline and a pressure relief plate arranged at the upper end of the pressure relief pipeline. A sealing layer for sealing the exhaust port at the upper end of the pressure relief pipeline is arranged on the lower surface of the pressure relief plate. A cover is arranged outside the pressure relief plate. An annular pressure relief port is arranged between the cover and the pressure relief pipeline. A plurality of elastic components are arranged between the cover and the pressure relief plate. When the pressure relief plate jacks up the elastic components upwards, gas is discharged through the exhaust port and the annular pressure relief port of the pressure relief pipeline.
[0005] Further, the elastic component includes an L-shaped bracket. A screw rod is arranged on the L-shaped bracket. An adjusting nut and a pressing ring are arranged on the upper part of the screw rod from top to bottom. The adjusting nut is in threaded cooperation with the screw rod, and the pressing ring can move along the screw rod. A spring is arranged between the adjusting nut and the pressing ring. The pressing ring presses against the upper surface of the pressure relief plate.
[0006] Further, three nuts screwed to the screw rod are arranged at the lower part of the screw rod, one of which is located above the L-shaped bracket and two are located below the L-shaped bracket.
[0007] Further, the L-shaped bracket includes a support plate A and a support plate B. The support plate A and the support plate B are perpendicularly arranged and fixed by bolts between the support plate A and the support plate B.
[0008] Further, a through hole is formed in the middle of the pressing ring, and the diameter of the through hole is larger than the diameter of the screw rod.
[0009] Further, an annular flange is arranged on the outer side of the lower end of the pressure relief pipeline, and fixing holes are arranged circumferentially on the annular flange.
[0010] Further, a lifting hook is arranged in the middle above the cover.
[0011] Further, the pressure relief pipeline includes a pipeline body and a fluorine-lined layer provided inside the pipeline body.
[0012] Compared with the prior art, the utility model has the following beneficial effects: the device has a simple structure and a reasonable design. When the pressure inside the pressure relief pipeline is relatively large, under the action of the pressure in the pressure relief pipeline, the pressure relief plate can overcome the spring force of the elastic component and jack up along the screw rod. The gas is discharged through the exhaust port and the annular pressure relief port of the pressure relief pipeline, thereby reducing the pressure inside the pressure relief pipeline. After the pressure inside the pressure relief pipeline becomes relatively small and returns to the normal state, the elastic force of the elastic component drives the pressure relief plate to fit and seal the pressure relief pipeline again.

Four elastic components 6 are evenly provided between the cover and the pressure relief plate. When the pressure inside the pressure relief pipeline is relatively large, the pressure relief plate overcomes the elastic force of the elastic component and jacks up. The pressure relief plate leaves the exhaust port of the pressure relief pipeline, and the gas is discharged through the exhaust port and the annular pressure relief port of the pressure relief pipeline, thereby reducing the pressure inside the pressure relief pipeline. After the pressure inside the pressure relief pipeline becomes relatively small and returns to the normal state, the elastic force of the elastic component drives the pressure relief plate to fit and seal the pressure relief pipeline again.
