Description

Technical Field

[0001] The utility model belongs to the technical field of deaerators, in particular to a water seal device for a deaerator. Background Art

[0002] The function of the deaerator is to remove oxygen from the water. In order to prevent corrosion of thermal equipment and its pipelines, the working principle is to use steam to form a steam saturation zone on the water surface, so that the oxygen in the water is automatically separated. During use, if the amount of steam input is too large, the steam pressure inside the deaerator will increase. The increase in steam pressure will cause the water level inside the deaerator to drop, and the steam pipeline originally submerged below the water level will be exposed. At this time, the steam cannot fully stir the water, and the secondary deoxygenation effect is significantly reduced.

[0003] At the same time, a self-replenishing overflow water seal device for a deaerator with application number 202020797280.4 is disclosed, comprising a water seal groove, a water replenishing pipe and a water supply pipe arranged on the deaerator, one end of the water supply pipe is connected with the water replenishing pipe, the end of the water replenishing pipe is connected with the water seal groove, an overflow port is arranged on one side of the water seal groove, a pipe is connected with the upper right end of the water seal groove, the end of the pipe is connected with a water tank, a water replenishing pump is arranged on the end of the pipe close to the water tank, support frames are arranged on the left and right sides of the water replenishing pump, and a water injection port is opened at the upper left end of the water tank. The device is suitable for a self-replenishing overflow water seal device for a deaerator, by arranging a water tank, a pipe, a water replenishing pump, a water injection port and a water replenishing pipe, and utilizing the mutual cooperation between them, so as to realize automatic water replenishment, reduce the operating burden of workers, improve the water seal performance, easy to use, simple structure, low manufacturing cost and strong practicality.

[0004] However, in the implementation of relevant technologies, the following problems were found: a deaerator self-replenishing overflow water seal device cannot automatically replenish water when the water level drops during use, which reduces the water seal performance of the deaerator and leads to a significant reduction in the secondary deoxygenation effect.

[0005] To this end, we proposed a deaerator water seal device. Utility Model Content

[0006] In order to solve the problems raised in the above background technology, the utility model provides a deaerator water seal device, which has the advantages of automatic water replenishment when the water level drops during use, improving the water seal performance of the deaerator and significantly improving the secondary deoxygenation effect.

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a deaerator water seal device, comprising a supporting base plate, a fixing block is fixedly provided on the top of the supporting base plate, a water tank is fixedly provided on the top of the fixing block, a valve body is fixedly provided on the outside of the water tank, a sealing plate is slidably provided on the lower part of the valve body, a sliding column is fixedly provided on the top of the sealing plate, a sealing gasket is fixedly provided on the top of the sliding column, a valve cover is fixedly provided on the top of the valve body, a first pipe is fixedly provided on the top of the valve cover, and the other end of the first pipe is fixedly connected to the lower part of the valve body.

[0008] Preferably, a second pipe is fixedly provided at the top of the valve cover, a connecting pipe is fixedly provided at the other end of the second pipe, an air intake housing is fixedly provided at the other end of the connecting pipe, an air inlet is opened at the top of the air intake housing, and a sealing column is slidably provided inside the air intake housing.

[0009] Preferably, a shaft base is fixedly provided on the outer side of the air intake housing, an extrusion plate is rotatably provided on the outer side of the shaft base, and the upper part of the extrusion plate is in contact with the other end of the sealing column.

[0010] Preferably, a fixing column is fixedly provided on the outer side of the extrusion plate, and a floating ball is fixedly provided on the other end of the fixing column.

[0011] Preferably, a fixing plate is fixedly provided on the top end of the supporting base plate, and the number of the fixing plates is two.

[0012] Preferably, a deaerator body is fixedly provided on the top end of the fixing plate, and the other end of the valve body is fixedly connected to the deaerator body.

[0013] Preferably, a spring is sleeved on the outer side of the sliding column, and the other end of the spring is in contact with the top end of the sealing plate.

[0014] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0015] 1. The utility model sets a float ball. When the water level inside the deaerator body drops, the drop in water level drives the float ball to move downward. The downward movement of the float ball drives the fixed column to rotate. The rotation of the fixed column drives the extrusion plate to rotate on the outside of the shaft base. The sealing column slides backward inside the air intake shell. Air enters the inside of the valve cover from the air inlet through the connecting pipe and the second pipe. The air enters the lower part of the valve body from the first pipe, so that the pressure inside the valve body is inconsistent. The pressure drives the sealing plate to move upward. The upward movement of the sealing plate drives the sliding column to move upward. The spring undergoes elastic deformation to stretch and contract. The water inside the water tank passes through the valve body into the deaerator body. After the water level is normal, the float ball rises and drives the extrusion plate to close the sealing column, so that the water level drops during use and the water can be automatically replenished, thereby improving the water seal performance of the deaerator and significantly improving the secondary deoxygenation effect.
