Problems solved by technology

Due to the large drop between the upper oil tank of the gas cabinet and the piston, and the insufficient processing precision of the gas cabinet, part of the sealing oil splashed onto the piston
In addition, the aging of the gas cabinet, the corrosion of the top plate of the gas cabinet, etc. will also cause rainwater to enter the gas cabinet piston. If the sealing oil and rainwater cannot be discharged in time, the gas cabinet piston will tilt, which will cause gas leakage, which will affect the normal operation of the gas cabinet. operation, but the existing drainage devices generally do not have good sealing and cannot be used for gas cabinets

Embodiment 1

[0020] see figure 1 , the present invention mainly includes a liquid storage tank 1, a liquid discharge pipe 2, an overflow pipe 3, a sewage pipe 4, a sewage valve 5, a sealing oil layer 6 and a plug 7.

[0021] The upper end of the liquid discharge pipe 2 communicates with the bottom of the piston 11, and the lower end extends into the liquid storage tank 1. The overflow pipe 3 is installed on the overflow port of the liquid storage tank 1, and the position of the overflow port is higher than that of the liquid discharge pipe 2. into the height of one end in the liquid storage tank 1.

[0022] In this embodiment, the accumulated water and oil on the piston 11 enters the liquid storage tank 1 through the drain pipe 2, and the oil and water in the liquid storage tank 1 are discharged to the bottom of the cabinet through the overflow pipe 3, and one end of the drain pipe 2 extends into the liquid storage tank 1, and the overflow pipe 3 is higher than the height of the lower end...

Embodiment 2

[0030] see figure 2 and image 3 , the present invention except comprising liquid storage tank 1, drain pipe 2, overflow pipe 3, drain pipe 4, drain valve 5, sealing oil layer 6, plug 7, also includes spring 8 and sealing plug 9.

[0031] The spring 8 is arranged in the discharge pipe 2 , and its lower end is fixed on the discharge pipe 2 . The sealing plug 9 is also arranged in the discharge pipe 2 , and the sealing plug 9 is connected with the upper end of the spring 8 .

[0032] A drain hole 10 is arranged on the side wall of the drain pipe 2, and the drain hole 10 is located below the overflow pipe 3. When the spring 8 is in a free state, the sealing plug 9 is located above the drain hole 10, and the spring 8 is compressed. In the state, the sealing plug 9 is located below the drain hole 10.

[0033] When the water on the piston 11 was less, the spring 8 was in a free state, and now the sealing plug 9 was positioned above the drain hole 10 to seal the piston 11 and the ...

Abstract

The invention discloses a liquid drainage device for a piston of a thin oil sealed gas chamber. The device comprises a liquid storage tank, a liquid drainage pipe and an overflow pipe, the liquid storage tank is located below the piston of the thin oil sealed gas chamber, the overflow pipe is installed above an overflow port in the upper part of the liquid storage tank, the liquid drainage pipe isvertically arranged, the lower end of the liquid drainage pipe is inserted into accumulated water in the liquid storage tank and is lower than the overflow port of the liquid storage tank, and the upper end of the liquid drainage pipe is fixed to the piston of the thin oil sealed gas chamber and communicates with the upper space of the piston. The invention also provides the thin oil sealed gas chamber containing the automatic oil water drainage device. The accumulated water and accumulated oil on the piston of the thin oil sealed gas chamber are discharged by utilizing the liquid drainage pipe, and a sealing mechanism composed of the liquid storage tank, the overflow pipe and the like is ingeniously designed. The device can smoothly discharge the accumulated water and the accumulated oilon the piston, also has good sealing property, can effectively prevent leakage of gas in the gas chamber, and can ensure safe operation of the gas chamber.

Description

technical field [0001] The invention relates to a piston draining device of a thin oil sealed gas cabinet and a thin oil sealed gas cabinet equipped with the piston draining device, belonging to the technical field of gas storage. Background technique [0002] Thin oil sealed gas cabinet is also called Man-type cabinet, its shape is a regular polygon, the outside is a regular polygonal prism reinforced shell structure composed of columns and L-shaped steel side plates, and the inside is composed of three parts: cabinet body, cabinet top and piston In addition, there are some ancillary facilities, such as external elevators, external stairs, various gas release pipes, etc. In order to save floor space, gas tanks are generally built higher, such as a total height of 100,000 cubic meters of gas tanks is 81.4 meters. During the operation of the gas cabinet, the sealing oil of the oil groove at the bottom of the cabinet flows into the oil-water separator for oil-water separation...
