Description

A liquid level control valve assembly and a liquid storage tank

technical field

The utility model relates to the field of valve machinery, in particular to a liquid level control valve assembly and a liquid storage tank.

Background technique

At present, water storage tanks (water storage tanks or liquid storage tanks or water storage tanks or liquid storage tanks) are used in many occasions. These water storage tanks are used to store domestic water or required liquids, etc., especially for high-rise buildings. Large water storage tanks are arranged on the roof and in the basement, and domestic water is stored in the large water storage tanks for use by users in the building.

In the water storage tank, the float valve is often used to control the water level to control the liquid level. However, the maximum volume stored in the water storage tank is fixed. As shown in Figure 1, the liquid level control valve assembly in the prior art includes: Water inlet pipe 20, one end of which communicates with the top of the water storage tank 10, and the other end communicates with the corresponding water source; float valve 23, which is arranged inside the water storage tank 10; liquid level control valve 21, which is arranged in the inlet The water pipe 20 is arranged near the entrance of the water inlet pipe 20 . The ball float valve 23 includes a ball float and a connecting rod 24, and the ball floats on the liquid surface all the time; one end of the connecting rod is connected with the ball float, and the other end of the connecting rod runs through the water storage tank 10 The side wall is connected with the liquid level control valve 21. When the liquid level where the float valve 23 is located is less than the preset liquid level Lc of the water storage tank 10, the float valve 23 controls the opening of the liquid level control valve 21, so that water or other corresponding liquids pass through The water inlet pipe 20 flows into the water storage tank 10 until the liquid level in the water storage tank 10 rises to the preset liquid level height Lc, the float valve 23 controls the liquid level control valve 21 If it is closed, water or other corresponding liquids will no longer flow into the water storage tank 10. The liquid level control valve assembly also includes a redundant valve 22, which is kept in a normally open state.

It can be seen that the existing liquid level control valve assembly cannot adjust the height of the storage liquid level (ie, the preset liquid level height Lc of the water storage tank) after construction and installation, that is, its volume is fixed and cannot be adjusted. And if changing the size and structure of water storage tanks, water tanks, water tanks or liquid storage tanks etc. in engineering, the cost is high, and it is impossible to set a plurality of water storage tanks with different volumes at any time along with the change of water storage volume.

However, in real life, there will always be a demand for volume changes such as pools. For example, people attach great importance to the quality of drinking water and do not want to store domestic water for too long, and the water consumption in summer is much larger than that in winter. Designed to store water in the worst case. When the water consumption is low in winter, the water stored in the pool will stay for a long time, so it is necessary to adjust the volume of the water storage tank. In some designs, the water storage volume in the pool needs to be adjusted, but it will increase the installation cost. Therefore, the current problem It cannot be solved at a reduced cost.
