At present, with the rapid development of economy in China, the gas consumption in industrial production and commercial life is greatly increased, and the gas uses include fuel gas, production gas, life gas, medical gas and the like. The range of conventional low-pressure gas generally refers to gas with working pressure below 0.1MPa, and the common low-pressure gas is mostly below 50KPa, and for the storage and transportation of such gas, a liquid seal device is generally used for sealing the gas in order to prevent gas leakage. In order to meet the sealing requirements of different low-pressure gases, various types of liquid seal tanks are developed, including single-stage, multi-stage, gravity type, differential pressure type, combined type and the like. However, the conventional liquid sealing method has many problems such as complex structure, difficult manufacturing, inconvenient maintenance, etc., so that it is necessary to continuously develop a new liquid sealing structure type that overcomes the above disadvantages and shortcomings.

The device is suitable for the top liquid seal or the tail end liquid seal of low-pressure equipment or pipelines, and can realize quick manual opening without tools.

The utility model adopts a combined structure of a quick-insert clapboard and a quick-open end cover, and comprises a liquid seal interface 1, a cylinder body 2, a liquid inlet pipe 3, a quick-insert clapboard 4, a quick-open end cover 5, an overflow pipe 6, a sight glass 7, a connecting pipe 8 and a collecting pipe 9; liquid seal interface 1 inserts and with 2 welded connection of barrel at 2 lower extremes of barrel, feed liquor pipe 3 and

overflow pipe

6 and 2 welded connection of barrel, insert baffle 4 soon and place inside 2 barrels, open end cover 5 soon and be connected with barrel 2 through the round pin axle at 2 tops of barrel, collecting pipe 9 is in 1 side of liquid seal interface and 1 welded connection of liquid seal interface, connecting pipe 8 adopts flange joint with overflow pipe 6 and collecting pipe 9 respectively, 7 flange joint of sight glass are on connecting pipe 8.

The top end cover of the device of the utility model can be opened quickly; a quick-insertion clapboard is arranged in the equipment to increase the liquid seal height; an overflow pipe is adopted to ensure the constant pressure height of the liquid seal; the adopted connecting pipe ensures that the sealing liquid cannot overflow.

The utility model discloses an arrange at (equipment) pipeline high point or pipeline end, need sealed gas to be inserted baffle 3 soon behind the 1 entering device barrel of liquid seal interface and stop, sealed liquid is filled liquid to 5 positions of overflow mouth by 3 entering of liquid import, opens the top 5 soon and is located 2 tops of device barrel for the device open fast. The overflow port 6 and the manifold 9 are connected by a connecting pipe 8 for recovery of the overflow liquid. Its advantage lies in, uses to insert baffle 4 soon and makes the liquid seal height of equipment increase 1 times under the condition that does not increase barrel 2 height, has effectively reduced the height of device, inserts the baffle soon and open the top cap soon and make the maintenance of device convenient and fast more, better satisfied the industry low pressure gas processing field to the technological requirement of gas seal.

The utility model has the advantages of, use and insert the baffle soon and make the liquid seal height-increasing 1 times of equipment under the condition that does not increase the barrel height, effectively reduced the height of device, insert the baffle soon and open the maintenance that the top cap made the device more convenient and fast, better satisfied industry low pressure gas treatment field to gas seal's technological requirement.

Detailed Description

The utility model discloses a liquid seal interface 1, barrel 2, feed liquor pipe 3, insert baffle 4 soon, open end cover 5, overflow pipe 6, sight glass 7, connecting pipe 8 soon, collecting pipe 9.

Wherein liquid seal interface 1 inserts and with 2 welded connection of barrel at 2 lower extremes of barrel, feed liquor pipe 3 and

overflow pipe

In the structural schematic diagram of the combined gas distributor shown in fig. 1, gas to be sealed enters the device cylinder 2 through the liquid seal interface 1 and then is blocked by the fast insertion partition plate 3, sealing liquid enters the liquid injection position to the overflow port 5 through the liquid inlet 3, and the fast opening top 5 is located above the device cylinder 2 and used for fast opening of the device. The overflow port 6 and the manifold 9 are connected by a connecting pipe 8 for recovery of the overflow liquid. Its advantage lies in, uses to insert baffle 4 soon and makes the liquid seal height of equipment increase 1 times under the condition that does not increase barrel 2 height, has effectively reduced the height of device, inserts the baffle soon and open the top cap soon and make the maintenance of device convenient and fast more, better satisfied the industry low pressure gas processing field to the technological requirement of gas seal.

In fig. 2, two support plates are used between the quick-opening end cover 5 and the barrel 2 for positioning, opening and closing the quick-opening end cover and the barrel, and a sight glass is arranged on the connecting pipe 8 for observing the overflow condition of the sealing liquid.

In fig. 3, insert baffle 4 soon and adopt three landing leg to support to set up the handle and conveniently take, the sealed liquid height in liquid seal height and the barrel 2 is relevant with the degree of depth of inserting sealed liquid fast and inserting 4 sleeves of baffle, and the maximum sealed height of limit is 2 times sealed liquid height.
