Description

Technical Field

[0001] This utility model relates to the field of integrated control valve technology, and in particular to an integrated control valve for gas tank walls. Background Technology

[0002] To control gas flow, control valves are often used. Control valves consist of two main components: the valve body assembly and the actuator assembly (or actuator system), and are categorized into four main series: single-seat control valves, double-seat control valves, sleeve control valves, and self-operated control valves. Variations of these four types of valves can lead to numerous different applicable configurations, each with its own specific applications, characteristics, advantages, and disadvantages. While some control valves have a wider range of applications than others, control valves are not suitable for all conditions; the best solutions for enhancing performance and reducing costs are developed by combining different valve types.

[0003] Currently, most control valves in gas containers are installed on the outside of the container, which takes up a lot of space and is inconvenient to use in confined spaces. To address this, we propose an integrated control valve for the gas container wall. Utility Model Content

[0004] The purpose of this utility model is to provide an integrated control valve for gas tank walls. By setting an integrated control valve structure, the valve can be opened or closed by using the cooperation of the isolation membrane, sealing gasket and back cover, and by checking whether the sealing gasket is tightly attached to the sealing tube. This not only places the integrated control valve inside the container tank, but also reduces the space occupied by the external space, and the overall structure is relatively compact.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an integrated control valve for a gas tank wall, comprising a tank wall, wherein an integrated control valve structure is installed inside the tank wall, and the integrated control valve structure includes:

[0006] An isolation membrane is disposed on one side inside the container wall, and a sealing gasket is fixedly connected to the outer surface of the isolation membrane;

[0007] The rear cover is fixedly connected to one side of the isolation membrane, and a back pressure cavity is formed between the rear cover and the isolation membrane;

[0008] A main air intake assembly, wherein the main air intake assembly is disposed on the side of the isolation membrane;

[0009] A main exhaust assembly, wherein the main exhaust assembly is disposed on the outer surface of the container tank wall;

[0010] An air intake control assembly is disposed on the side of the rear cover;

[0011] A control exhaust assembly is provided at the bottom of the rear cover.

[0012] Preferably, the exhaust control assembly includes:

[0013] A control tube, which is fixedly connected to the bottom end of the rear cover;

[0014] An electrically controlled valve, wherein the electrically controlled valve is installed at the end of the control pipe that passes through the outer side of the container wall;

[0015] A control exhaust port is fixedly connected to the end of the electrically controlled valve.

[0016] Preferably, a bushing is provided between the rear cover and the container wall, and a cavity is provided between the isolation membrane and the container wall.

[0017] Preferably, the main exhaust assembly includes a sealing pipe and a main exhaust port opened inside the sealing pipe, and one end of the sealing pipe extends into the inner side of the container wall.

[0018] Preferably, the sealing gasket is fixedly connected to the middle of the isolation membrane, and the position of the sealing gasket corresponds to the position of the sealing tube.

[0019] Preferably, the main exhaust assembly includes a main air inlet, and the main air inlet is located on the side of the cavity.

[0020] Preferably, the controlled air intake assembly includes a back pressure air intake port, the inner diameter of which is smaller than the inner diameter of the controlled exhaust port.

[0021] Preferably, the sealing gasket is made of rubber, and the outer contour dimension of the sealing gasket is larger than the outer diameter dimension of the sealing tube.

[0022] The technical effects and advantages of this utility model are as follows:

[0023] Air is introduced by controlling the intake assembly. At this time, the pressure decreases due to the gas flow in the back pressure chamber. The diaphragm moves the sealing gasket away from the main exhaust assembly, allowing the main intake assembly to take in air and the main exhaust assembly to discharge gas. Subsequently, when the exhaust assembly stops discharging gas, the pressure inside the back pressure chamber gradually returns to its original state due to the continuous intake of air by the intake assembly. This causes the diaphragm to move the sealing gasket tightly against the main exhaust assembly, thereby closing the integrated control valve structure. This design, by setting an integrated control valve structure, has the advantages of being thin, saving space, integrating with the container tank, having a compact structure, large flow rate, and being able to make the opening larger. It can also be used in low-pressure conditions. Attached Figure Description

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] This utility model provides, for example Figure 1-2 The diagram shows an integrated control valve for the gas tank wall.

[0029] Example 1

[0030] The container includes a tank wall 1, inside which an integrated control valve structure is installed. The integrated control valve structure includes: an isolation membrane 2, which is located on one side inside the tank wall 1, and a sealing gasket 6 is fixedly connected to its outer surface; a rear cover 3, which is fixedly connected to one side of the isolation membrane 2, forming a back pressure chamber 4 between the rear cover 3 and the isolation membrane 2; a main air intake assembly, located on the side of the isolation membrane 2; a main exhaust assembly, located on the outer surface of the tank wall 1; a control air intake assembly, located on the side of the rear cover 3; and a control exhaust assembly, located at the bottom of the rear cover 3. The control valve structure controls the air intake... When the air intake component is activated, the pressure decreases due to the gas flow in the back pressure chamber 4. The isolation diaphragm 2 moves the sealing gasket 6 away from the main exhaust component, allowing the main intake component to take in air and the main exhaust component to discharge gas. Subsequently, when the exhaust component stops venting, the pressure inside the back pressure chamber 4 gradually returns to its original state due to the continuous intake of air by the intake component. This causes the isolation diaphragm 2 to move the sealing gasket 6 tightly against the main exhaust component, thereby closing the integrated control valve structure. This design, by setting an integrated control valve structure, has the advantages of being thinner, saving space, integrating with the container tank, having a compact structure, large flow rate, and a large opening, and can also be used in low-pressure conditions.

[0031] Furthermore, the exhaust control assembly includes: a control pipe 11, which is fixedly connected to the bottom end of the rear cover 3; an electric control valve 10, which is installed at the end of the control pipe 11 that passes through the outer side of the container wall 1; and a control exhaust port 9, which is fixedly connected to the end of the electric control valve 10. By opening the electric control valve 10, the gas in the back pressure chamber 4 is discharged from the control pipe 11 to the control exhaust port 9, thereby realizing the exhaust function of the exhaust control assembly.

[0032] Furthermore, a bushing 13 is provided between the rear cover 3 and the container wall 1, and a cavity 5 is provided between the isolation membrane 2 and the container wall 1; this facilitates the discharge of gas from the cavity 5 through the main exhaust assembly.

[0033] Furthermore, the main exhaust assembly includes a sealing pipe 7 and a main exhaust port 8 opened inside the sealing pipe 7, and one end of the sealing pipe 7 extends into the inner side of the container wall 1; exhaust is carried out through the main exhaust port 8 on the sealing pipe 7.

[0034] Furthermore, the sealing gasket 6 is fixedly connected to the middle of the isolation membrane 2, and the position of the sealing gasket 6 corresponds to the position of the sealing tube 7; by the sealing gasket 6 tightly adhering to the sealing tube 7, a compression seal is achieved.

[0035] Furthermore, the main exhaust assembly includes a main air intake 14, which is located on the side of the cavity 5; air intake is achieved through the main air intake 14.

[0036] Furthermore, the control intake assembly includes a back pressure intake port 12, the inner diameter of which is smaller than the inner diameter of the control exhaust port 9; after the control exhaust port 9 is opened, the exhaust velocity is greater than the intake velocity at the back pressure intake port 12, thereby reducing the pressure inside the back pressure chamber 4.

[0037] Example 2

[0038] Example 2 further discloses, based on Example 1, that: the sealing gasket 6 is made of rubber, and the outer contour dimension of the sealing gasket 6 is larger than the outer diameter dimension of the sealing tube 7; this allows the sealing gasket 6 to fit the sealing tube 7 better, thereby achieving a good sealing effect and preventing gas from escaping from the main exhaust port 8.

[0039] Working principle of this utility model:

[0040] Closed state: When the external electric control valve 10 is closed, there is no gas flow in the control pipe 11. The gas in the container enters the back pressure chamber 4 through the back pressure inlet 12. The force relationship between the two sides of the isolation membrane 2 is as follows: the force area on the back pressure side is equal to the area of ​​the cavity 5 plus the area of ​​the main exhaust port 8. When there is no airflow in the control pipe 11, the pressure in the back pressure chamber 4 is consistent with that of the container through the back pressure inlet 12. On the other side, only the cavity 5 has pressure, which is also consistent with that of the container. There is no pressure on the main exhaust port 8 side. At this time, the back pressure will push the isolation membrane 2 forward until the sealing gasket 6 contacts and presses against the sealing pipe 7. In this case, the valve is closed and is in the closed state.

[0041] Open state: When the solenoid valve 10 receives a control signal and opens the control pipe 11, the gas in the back pressure chamber 4 will be discharged. Since the opening of the back pressure inlet 12 is smaller than the control exhaust port 9, the gas in the container tank cannot be replenished to the back pressure chamber 4 in time. At this time, the pressure in the back pressure chamber 4 decreases, and the pressure in the chamber 5 pushes the isolation membrane 2 to the side of the back pressure chamber 4, forcing the sealing gasket 6 to separate from the sealing pipe 7. In this case, the valve is in the open state. After the solenoid valve 10 is closed again and the gas flow in the control pipe 11 is stopped, the pressure in the back pressure chamber 4 is restored, and the valve is closed.

[0042] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
