Description

Technical Field

[0001] This utility model relates to the field of pressure vessel equipment technology, and in particular to a container valve. Background Technology

[0002] Currently used pressure vessel valves typically employ ball valves for opening and closing, requiring manual operation, which poses certain safety risks to operators. While diaphragm-type devices can also open the vessel, this method uses an electrically activated needle to puncture the diaphragm for remote opening. However, because the punctured diaphragm cannot be restored, this method makes valve closure difficult, resulting in continuous discharge of material from the vessel until it is empty. Even with additional valves installed at the outlet, material will still leak out through the punctured diaphragm, failing to achieve true closure. Utility Model Content

[0027] Exemplary embodiments of the present disclosure will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.

[0028] like Figure 1 As shown, an embodiment of this utility model provides a container valve, comprising:

[0029] A valve body 2 is installed at the opening of container 19, and a portion of the valve body 2 is placed inside container 19;

[0030] The valve core 3 is located at the center of the valve body 2;

[0031] The valve cover 7 is located at the top of the valve body 2;

[0032] An air core cap 16 is installed at the center of the bottom of the valve cover 7;

[0033] An electric starter 8 is installed at the center of the top of the valve cover 7.

[0034] In this embodiment, the container valve is mainly used to control the sealing and release of the extinguishing agent and other media stored in the container 19. Through reasonable structural design, the container 19 can be repeatedly opened and closed, ensuring that the container 19 can be opened or closed accurately and quickly when needed, thereby ensuring the normal operation of the system to achieve the expected fire extinguishing effect.

[0035] The valve body 2 is installed at the opening of the container 19, and part of the valve body 2 is placed inside the container 19, so that the valve body 2 can be tightly combined with the container 19 to form a whole, preventing the container valve from being forced to detach from the container 19 due to excessive internal pressure when the medium is released; the valve body 2 is usually made of high-strength metal material, such as stainless steel or alloy steel, to ensure that it can withstand the pressure of the medium inside the container 19, ensuring the reliability and safety of the seal; the shape of the valve body 2 is designed as cylindrical or other structures suitable for the shape of the container opening, so as to facilitate precise matching and installation with the opening of the container 19.

[0036] The valve core 3 is located in the center of the valve body 2. Its main function is to control the flow of the medium. The material selection of the valve core 3 mainly takes into account factors such as the properties, pressure and temperature of the medium. Corrosion-resistant and high-strength materials are used to ensure sealing performance and mechanical strength. When it is necessary to open the container valve, the valve core 3 moves upward, thereby opening the medium flow channel and allowing the medium to flow out of the container 19. The actuation accuracy and sealing performance of the valve core 3 directly affect the opening and closing effect of the container valve, as well as the safety and reliability of the entire system.

[0037] The valve cover 7 is located on top of the valve body 2. The valve cover 7 is circular or has a shape corresponding to the top of the valve body 2. Its size and design need to take into account the fitting accuracy with the valve body 2 and the installation requirements of the internal components. The valve cover 7 has a groove structure designed at the center of the top and bottom to match the installed components.

[0038] The air core cap 16 is installed at the center of the bottom of the valve cover 7. Its shape and size are designed according to the groove structure at the bottom of the valve cover 7. It adopts a cylindrical shape or other suitable installation structure. The material is selected from materials with certain elasticity and sealing properties, such as plastic. The air core cap 16 plays a role in assisting sealing and controlling the flow of media in the container valve. When the container valve is in the closed state, the air core cap 16 is closely matched with other components to further enhance the sealing performance and prevent media leakage.

[0039] The electric starter 8 is installed at the center of the top of the valve cover 7. Its structure includes a housing and internal electrical components. The housing is made of high-strength insulating material to protect the internal electrical components from the influence of the external environment and to ensure the safety of the operator. The size and shape design of the electric starter 8 need to take into account the installation fit with the valve cover 7 and the ease of operation. The electric starter 8 is one of the starting components of the container valve. It opens the container valve by receiving external electrical signals. When the internal electrical components of the electric starter 8 receive the corresponding electrical signals, they will drive the internal components to move, thereby opening the container valve.

[0040] like Figure 1 As shown, in an optional embodiment of the present invention, the valve body 2 is hollow inside and has a nozzle 5 on one side of the axial center. The hollow part is divided into a top cavity 17 and a bottom cavity 1 by the valve core 3. A first through hole 18 is opened at the center of the bottom of the valve core 3, and the top cavity 17 and the bottom cavity 1 are connected through the first through hole 18. The valve core 3 and the valve body 2 are sealed together by a third sealing ring 4, which is installed on the valve core 3.

[0041] In this embodiment, the valve body 2 is designed with a hollow structure, providing sufficient space for the installation and operation of the valve core 3, allowing the valve core 3 to slide freely inside the valve body 2, ensuring that the medium can flow smoothly from the container 19 or be blocked. The nozzle 5 is located on one side of the axial center of the valve body 2. The location on one side of the axial center allows the medium to have good directionality and diffusion when flowing out. When the container valve is opened, the medium flows from inside the valve body 2 to the nozzle 5. The shape and size of the nozzle 5 will affect the spray speed, range and shape of the medium. For example, the nozzle 5 can be designed as a circle, square or other special shape to meet the requirements of medium spraying in different application scenarios. In the fire protection system, the reasonable design of the structure of the nozzle 5 can ensure that the extinguishing agent is accurately sprayed to the fire area and improve the fire extinguishing efficiency.

[0042] The valve core 3 is installed inside the valve body 2, dividing the hollow portion of the valve body 2 into the top cavity 17 and the bottom cavity 1, thus forming two relatively independent but interconnected spaces inside the valve body 2. When the container valve is closed, because the pressure in the top cavity 17 and the bottom cavity 1 is the same, the bottom cavity 1, the top cavity 17, and the nozzle 5 are separated by the valve core 3, and the medium cannot flow to the outside. When the container valve is opened, the pressure between the top cavity 17 and the bottom cavity 1 changes, pushing the valve core 3 upward, connecting the bottom cavity 1 with the nozzle 5, and allowing the medium to flow to the outside through the nozzle 5.

[0043] The valve core 3 and the valve body 2 are sealed together by the third sealing ring 4, preventing media leakage through the gap between them. When the valve is closed, the third sealing ring 4 fits tightly between the valve core 3 and the valve body 2, forming a sealing barrier to ensure the media does not leak to the outside, thus guaranteeing the system's safety and stability. The third sealing ring 4 is installed on the valve core 3, facilitating installation and maintenance. During installation, the third sealing ring 4 is fitted onto the corresponding slot of the valve core 3 and then assembled with the valve body 2 to achieve a sealed connection. Similarly, when the third sealing ring 4 wears or ages, it is easy to replace, reducing maintenance costs and difficulty. Furthermore, the third sealing ring 4 installed on the valve core 3 can move vertically with the movement of the valve core 3, always maintaining a tight fit with the valve body 2, ensuring stable sealing performance.

[0044] like Figure 1 As shown, in an optional embodiment of the present invention, the valve cover 7 is provided with an inclined pressure relief hole 10 and a vertical second through hole 11; the valve cover 7 and the valve body 2 are sealed together by a second sealing ring 6, which is installed on the valve body 2.

[0045] In this embodiment, the valve cover 7 has an inclined pressure relief hole 10. The inclination angle can change the direction and speed of the medium ejected from the pressure relief hole 10. When the internal pressure of the container is too high and pressure relief is required, the medium is ejected from the pressure relief hole 10. The inclination angle can cause the medium to diffuse outward at an angle, reducing the direct impact of the medium on surrounding components and reducing the risk of damage to the surrounding environment and equipment. The pressure relief hole 10 can also affect the pressure relief efficiency. According to the changes in the internal pressure of the container, the outflow speed and flow rate of the medium can be flexibly adjusted to avoid the formation of local eddies or pressure concentrations in the medium during the pressure relief process, ensuring the smooth progress of the pressure relief process.

[0046] The second through hole 11 on the valve cover 7 is mainly for accommodating the components in the extended electric starter 8. Since the second through hole 11 is vertically opened, it can maintain a relatively stable shape and position when subjected to external force or medium flow, and is not easily deformed or damaged. This ensures that the components connected to the second through hole 11 work normally, and ensures the reliability and stability of the entire system.

[0047] The valve cover 7 and the valve body 2 are sealed together by the second sealing ring 6. The main function of the second sealing ring 6 is to prevent the medium from leaking through the gap between the valve cover 7 and the valve body 2. The second sealing ring 6 can tightly fit the contact surface of the valve cover 7 and the valve body 2, forming a sealing barrier to prevent the medium from leaking out and ensuring the safety and stability of the system. The second sealing ring 6 is installed on the valve body 2. When the second sealing ring 6 is worn or aged and needs to be replaced, it can be replaced simply by removing the valve cover 7, without the need for large-scale disassembly of the valve body 2 or the valve cover 7, thus reducing maintenance costs and difficulty.

[0048] like Figure 1 As shown, in an optional embodiment of the present invention, the air core cap 16 includes:

[0049] An air core 12 is located at the top of the air core cap 16. The air core 12 and the air core cap 16 are sealed together by a first sealing ring 13, which is installed on the air core 12.

[0050] A return spring 15 connects the bottom surface of the air core 12 to the bottom first surface of the air core cap 16;

[0051] The third through holes 14 are located on both sides of the air core cap 16.

[0052] In this embodiment, the air core 12 is located at the top of the air core cap 16, and its main function is to control the flow of the medium. When the container valve needs to release the medium, the air core 12 moves downward to open the medium channel, allowing the medium to flow smoothly out of the container; when the medium does not need to be released, the air core 12 moves upward to close the channel and prevent medium leakage.

[0053] The air core 12 and the air core cap 16 are sealed together by the first sealing ring 13. The main function of the first sealing ring 13 is to prevent the medium from leaking through the gap between the air core 12 and the air core cap 16, and to prevent the pressure inside the container from dropping, which would affect the normal operation of the container valve. The first sealing ring 13 is installed on the air core 12. When assembling the air core 12 and the air core cap 16, the first sealing ring 13 is first installed on the air core 12, and then the air core 12 is placed into the air core cap 16. When the air core 12 moves, the first sealing ring 13 can move with the air core 12, always maintaining a tight fit with the air core cap 16 to prevent medium leakage.

[0054] The reset spring 15 connects the bottom surface of the air core 12 to the first surface of the bottom of the air core cap 16, so that the reset spring 15 can provide stable support and reset force for the air core 12. When the air core 12 is subjected to the external force of the electric start device 8 and moves downward, the reset spring 15 will be compressed, generating an upward force. When the external force disappears, the upward force generated by the reset spring 15 will push the air core 12 to move upward until it is reset.

[0055] The third through hole 14 is a channel for medium flow and can also play a role in balancing pressure. When the container valve is started, the medium needs to flow through the third through hole 14 to flow into the upper part of the air core 12, and then flow out of the device through the pressure relief hole 11 to achieve the pressure relief effect.

[0056] like Figure 1 As shown, in an optional embodiment of the present invention, the orifice area of ​​the pressure relief hole 10 is greater than or equal to the orifice area of ​​the third through hole 14, and the orifice area of ​​the pressure relief hole 10 is greater than the orifice area of ​​the first through hole 18.

[0057] In this embodiment, the orifice area of ​​the pressure relief hole 10 is ensured to be greater than or equal to the orifice area of ​​the third through hole 14. This ensures that the medium flowing into the third through hole 14 can be discharged out of the device at the same speed or faster, preventing the medium from accumulating in the gas core cap 16 and causing excessive pressure in the gas core cap 16 to affect the device. The orifice area of ​​the pressure relief hole 10 is greater than the orifice area of ​​the first through hole 18, thereby ensuring that the medium from the bottom cavity 1 to the top cavity 17 can be discharged in time. The pressure in the top cavity 17 is always less than that in the bottom cavity 1, thus keeping the valve in the discharge state.

[0058] like Figure 1 As shown, in an optional embodiment of the present invention, a needle 9 is installed in the central position inside the electric starting device 8, and the needle 9 slides within the second through hole 11.

[0059] In this embodiment, the electric starter 8 performs start and stop commands. When the electric starter 8 receives a start signal, the needle 9 slides downward through the second through hole 11 and maintains this operation. At this time, the air core 12 moves to a position below the third through hole 14. The medium in the container passes through the bottom cavity 1, the top cavity 17, and the air core cap 16 until it is discharged from the device, thereby making the pressure in the top cavity 17 less than that in the bottom cavity 1. The pressure in the bottom cavity 1 pushes the valve core 3 to move upward, thereby causing the medium in the container 19 to be continuously sprayed out through the nozzle 5. When the electric starter 8 receives a stop signal or the start signal ends automatically, the needle 9 retracts, the return spring 15 pushes the air core 12 to reset, the pressure relief channel at the top of the container valve is blocked, the pressure in the top cavity 17 and the bottom cavity 1 in the device are consistent, the valve core 3 returns to its original position, and the medium stops spraying.

[0060] The above embodiments of this utility model ensure personnel safety, realize remote opening and closing of the container, and realize the movement of the internal channel blocking component of the container through the electric start device, so that the medium in the pressure vessel can be released or stopped according to actual needs, without the need for on-site manual operation, eliminating personal safety hazards when opening and closing the pressure vessel. At the same time, it can also realize the true closure of the pressure vessel according to the use needs, and can utilize the remaining medium in the container, reducing economic losses.

[0061] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
