Based on the water seal structure, the water seal pipe 53 can realize the water seal height matched with the operating pressure in the gas chamber, effectively seal the gas in the gas chamber and prevent the gas from escaping; through set up broken siphon suction opening 534 on water seal pipe 53, on the one hand through the characteristics of this broken siphon suction opening 534 and atmosphere intercommunication, avoid forming the siphon phenomenon between leading water pipe 51 and the water seal structure, on the other hand can directly realize the water seal through this broken siphon suction opening 534 pouring water in water seal pipe 53, convenient operation is reliable.

It will be appreciated that the siphon break opening 534 is preferably located above the overflow section 532, rather than opening directly into the overflow section 532, such as by-passing a siphon break through the overflow section 532, which extends upwardly from a point of by-pass in the overflow section 532, the top opening of which constitutes the siphon break opening 534. The broken siphon can be connected to the middle part of the overflow section 532, and forms a three-way pipe body with the overflow section 532; or the broken siphon is connected to the inlet end of the overflow section 532, so that the broken siphon, the overflow section 532 and the adjacent water seal section 531 form a three-way pipe body; obviously, in order to facilitate the filling of water into the water seal section 531 from the siphon breaking suction opening 534, it is preferable to adopt the latter mode, that is, the siphon breaking pipe is connected to the inlet end of the overflow section 532, for example, the siphon breaking pipe is formed by extending upward from the adjacent water seal section 531.

The drain 535 is preferably kept in a closed state during normal operation of the gas holder, and may be controlled by a drain valve or the like. The drain 535 is preferably disposed at the lowest point of the water sealing section 531, for example, for the U-shaped water sealing section 531, it is defined that it includes a first vertical pipe connected to the water conduit 51, a second vertical pipe connected to the overflow section 532, and a horizontal pipe connecting the first vertical pipe and the second vertical pipe, the horizontal pipe is the lowest pipe body of the water sealing section 531, and the drain 535 may be disposed on the horizontal pipe.

Obviously, the height of the overflow section 532 determines the maximum water seal height of the water seal section 531, and specifically, the height of the tube center of the overflow section 532 is defined as h, which meets the following requirements:

h＝h0+h1+h2+h3

wherein h0 is the elevation of the upper surface of the cabinet body bottom plate 2; h1 is the elevation corresponding to the gas pressure in the cabinet; h2 is half of the pipe diameter of the overflow section 532; h3 is the height of the inlet end of the penstock 51 protruding out of the bottom plate of the cabinet.

In another embodiment, as shown in fig. 2 and 3, the water conduit 51 is positioned above the bottom plate of the cabinet and extends to the drain pit 52 after sequentially passing through the oil drain baffle 3, the annular oil drain 4 and the cabinet side plate 1.

When the gas tank is stopped for maintenance, the inside of the gas tank is communicated with the atmosphere and is not pressurized, if the bottom plate 2 of the tank body is heavily accumulated with water, the drainage control valve 541 is opened, and the accumulated water on the bottom plate 2 of the tank body can be at least partially drained into the drainage pit 52 through the drainage branch pipe 54; particularly, the drainage branch pipe 54 is matched with the sewage draining outlet 535, so that accumulated water on the bottom plate 2 of the cabinet body can be drained quickly. Alternatively, if the space between the penstock 51 and the drain sump 52 limits the placement of the drain branch 54, as shown in fig. 2 and 3, the drain branch 54 may be placed over the drain sump 52 into the drain sump 52. In one embodiment, the drain control valve 541 is an extension rod valve for easy operation.
