Description

Technical Field

[0001] The utility model belongs to the technical field of water storage tanks, and in particular relates to a gas storage and exhaust device for a water storage tank. Background Art

[0002] Water tanks generally have water inlets and outlets. In order to ensure the normal water inlet and outlet of the water tank, the water tank must have an exhaust port. Generally, a straight exhaust pipe is installed on the top of the tank to discharge the gas directly, but there is a defect in direct discharge. When the water inflow is large, water vapor will be discharged from the exhaust port, that is, the gas will bring some water out, which makes the tank body often wetted by water. On the one hand, this causes the equipment to be dirty and affects the environmental hygiene. At the same time, it will cause corrosion to the tank body and surrounding pipes, which will increase the maintenance time of the equipment and the replacement rate of spare parts over time. Summary of the invention

[0003] To solve the above problems, the present application provides a water tank gas storage and exhaust device, which aims to store the gas exhausted from the water tank in the gas tank, and exhaust the gas through an exhaust valve while collecting water in the gas through a water receiving tray, thereby avoiding corrosion to the equipment and ensuring environmental hygiene, and has a simple structure and low cost.

[0008] As an improvement of the above solution, a pressure gauge is provided on the gas storage tank to detect the pressure in the gas storage tank.

[0009] As an improvement of the above solution, the air inlet pipe, the air outlet pipe and the drain pipe are all made of PPR material, so that the pipes are corrosion-resistant and the service life is increased.

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1-2 The present embodiment provides an air storage and exhaust device for a water storage tank A, comprising an air storage tank 1 and a water receiving tray 5. The bottom of the air storage tank 1 is connected to an air inlet pipe 2, and the top is connected to an air outlet pipe 3. An exhaust valve 4 is provided on the air outlet pipe 3.

[0022] The gas storage tank 1 is located above the water storage tank A and is connected to the exhaust port at the top of the water storage tank A through the air intake pipe 2, so that the gas generated in the water storage tank A enters the gas storage tank 1 through the air intake pipe 2 for storage and discharge.

[0023] The water receiving pan 5 is located below the gas storage tank 1. The water receiving pan 5 is funnel-shaped, and its vertical projection area is larger than the vertical projection area of ​​the gas storage tank 1. The gas storage tank 1 is located above the center of the water receiving pan 5 to fully collect water dripping from around the gas storage tank 1. The bottom of the water receiving pan 5 is connected to a drain pipe 6. The water carried in the gas discharged from the gas outlet pipe 3 drips into the water receiving pan 5 for collection, and is finally discharged through the drain pipe 6.

[0024] In this embodiment, the volume of the gas tank 1 is set to 5L, and the volume of the water tank A is much larger than that of the gas tank 1. Collecting water in the gas discharged from the gas tank 1 through the water receiving tray 5 is simpler and more convenient than collecting water in the exhaust gas in the water tank A, and the area of ​​the water receiving tray 5 is small, thereby reducing costs.

[0025] in,

[0026] The air intake pipe 2, the exhaust pipe and the drain pipe 6 are all made of PPR material. Since the fluids in these three pipes contain water, the PPR material is corrosion-resistant, thereby increasing the service life of the pipes.

[0027] The exhaust valve 4 is provided with a pressure gauge for detecting the pressure in the gas storage tank 1 .

[0028] See also Figure 3 The exhaust valve 4 comprises a valve body 45, an exhaust valve 41, an exhaust cover plate 42, a pressure piston 43 and a pressure spring 44 located in the valve body 45. The pressure cover plate 42 is connected to the wall of the valve body in a circle, and an air outlet is formed in the middle of the pressure cover plate. The exhaust valve 41 is located above the air outlet. The top of the pressure piston 43 is vertically connected to the bottom of the exhaust valve 41, and its bottom is connected to the pressure spring 44. The pressure spring 44 is connected to the bottom of the valve body 45. Specifically, two pressure springs 44 are provided in a left and right bifurcation, and the tops of the two pressure springs 44 are connected to the bottom of the pressure piston 43. The gas is introduced from the bottom of the valve body 45. When the gas pressure reaches a certain value, the valve 41 is pushed up by the pressure, so that the valve 41 and the exhaust cover plate 42 are separated. At this time, the exhaust valve 4 is in an open state, and the gas is discharged upward from the gap between the valve 41 and the exhaust cover plate 42. When the pressure in the valve body 45 decreases, the valve 41 falls back and fits on the exhaust cover plate 42 under the action of the pressure spring 44. At this time, the exhaust valve 4 is in a closed state.

[0029] The gas storage and exhaust device for the water storage tank A of this embodiment further includes a bracket, and the gas storage tank 1 and the water receiving tray 5 are both fixedly connected to the bracket by suspension.

[0030] In production, there may be more than one water storage tank A, and the exhaust port of each water storage tank A is connected to the gas storage tank 1. The volume of the gas storage tank 1 can be adjusted according to the actual total number and volume of water storage tanks A. Centralized exhaust is achieved through the gas storage tank 1, and the water in the gas is collected centrally.

[0031] The working process of the gas storage and exhaust device for water storage tank A in this embodiment is as follows:

[0032] When water is being taken in to the water tank A, the gas generated in the water tank A is discharged from the exhaust port and enters the gas tank 1 through the intake pipe 2. The water carried in the gas is also stored in the gas tank 1. When the gas pressure in the gas tank 1 reaches a certain value, the exhaust valve 4 opens, and the gas in the gas tank 1 is discharged through the outlet pipe 3. The discharged gas enters the surrounding air, and the water in the gas falls on the water receiving tray 5 and is then discharged through the drain pipe 6. After exhaust, the pressure in the gas tank 1 is reduced, and the exhaust valve 4 returns to the closed state.

[0033] It should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
