Description

Automatic water replenishment water seal controlled by double floats

technical field

The invention relates to an automatic water replenishment water seal, in particular to a water seal which uses double floating balls to control the minimum water level on both sides of the water seal to automatically replenish water and can cope with bidirectional pressure changes.

Background technique

The patent "A Water-Sealed Tank for Automatic Replenishment" with the authorized announcement number CN2486621 discloses a water-sealed tank used in the chemical industry where toxic, harmful, flammable and explosive gases are used. It can automatically maintain the water level in the tank. However, the water-sealed tank is not good at dealing with the two-way change of the gas pressure in the sealed system, and has the defect of low safety in use. The water-sealed tank can only cope with changes in the gas pressure rise in the sealed system, and cannot cope with changes in the gas pressure in the sealed system being lower than the outside world. When the gas pressure in the sealed system rises to a certain level, the gas rushes out of the water-sealed tank and releases the excessive pressure; when the pressure in the sealed system is lower than the external pressure to a certain level, the sealing pressure is small, Moreover, the water in the water-sealed tank will be sucked into the sealed system, which may cause damage to the sealed system.

Contents of the invention

The purpose of the present invention is to provide an automatic replenishment water seal controlled by double floats, so as to overcome the defect that the water seal tank in the prior art cannot cope with the two-way change of the gas pressure in the sealed system and has low safety in use. The invention has the feature of adopting double floating balls to control the minimum water level on both sides of the water seal to automatically replenish water. It includes a water-sealed tank body 1 and a ball float valve 5. It also includes No. 1 floating ball 2, No. 2 floating ball 3, fork rod 4 and a partition 6. The partition 6 set in the plumb direction is fixed on the water-sealed tank body 1. The upper half of the inside and the upper half of the inner cavity of the water-sealed tank body 1 are divided into a closed cavity 1-1 and a pressure relief cavity 1-2, and a No. 1 through hole 1-3 is opened on the top of the closed cavity 1-1 , the top of the pressure relief chamber 1-2 is provided with a No. 2 through hole 1-4, the No. 1 float 2 is arranged in the closed chamber 1-1, the No. 2 float 3 is arranged in the pressure relief chamber 1-2, and the float valve 5 is arranged on the inner wall of the water-sealed tank 1 and is located below the partition 6. The rear end of the fork rod 4 is connected to the float valve 5 to control the opening and closing of the float valve 5. One front end of the fork rod 4 is fixed on On the No. 1 floating ball 2, the other front end of the fork bar 4 is fixed on the No. 2 floating ball 3.

When the water sealing device of the present invention is in operation, the No. 1 through hole 1-3 is connected to the sealed system, and the No. 2 through hole 1-4 is connected to the atmosphere. The edge prevents the gas in the closed chamber 1-1 and the pressure relief chamber 1-2 from communicating with each other, so that the gas in the sealed system cannot leak. When the gas pressure in the sealed system rises and makes the water level in the closed chamber 1-1 lower than the lower edge of the partition 6, the gas in the closed chamber 1-1 bypasses the lower edge of the partition 6 and rushes out of the pressure relief chamber 1-2 of the water surface, so as to release the excessive pressure. When the gas pressure in the sealed system decreases and the water level in the pressure relief chamber 1-2 is lower than the lower edge of the partition 6, the gas in the pressure relief chamber 1-2, which is connected to the outside atmosphere, bypasses the bottom of the partition 6 The lower edge rushes out of the water surface in the airtight chamber 1-1, thereby changing the situation that the pressure in the airtight chamber 1-1 is too low, and avoiding water being sucked into the sealed system. The invention can automatically balance the pressure when the gas pressure in the sealed system changes, and overcomes the defect that the water-sealed tank in the prior art cannot cope with the two-way change of the gas pressure in the sealed system, so the safety is high.
