A quick-opening valve

Abstract

This utility model discloses an instant-opening valve, aiming to solve the problem of insufficient gas impact strength and powder residue in pipeline towers caused by premature gas leakage when the valve stem detaches from the valve port in existing instant-opening valves. The instant-opening valve is installed inside a gas storage tank and includes an instant-opening valve cylinder. One end of the cylinder has a valve cap with a valve outlet. A Laval tube is located on the outer end of the outlet, and a hollow cylinder is located on the inner end, forming a ventilation gap between the hollow cylinder and the inner wall of the cylinder. A vent hole is located on the side wall of the cylinder near the outlet, and a piston is located inside. A valve seal, adapted to the circumference of the hollow cylinder, is located on the side of the piston facing the outlet. When the valve seal is in contact with the circumference of the hollow cylinder, it isolates the interior of the gas storage tank from the outlet; when separated, it allows for connection. The Laval tube passes through the gas port of the gas storage tank and is sealed. This structure can prevent premature gas leakage, ensure concentrated and instantaneous gas release and impact strength, and effectively remove powder from pipeline towers.

Description

Technical Field

[0001] This utility model relates to the field of fluid control technology, and in particular to an instantaneous opening valve. Background Technology

[0002] In the powder production process, periodic gas impact is typically used to clean the powder inside the pipeline tower to prevent powder deposition. This periodic gas needs to have sufficient impact force. While existing technologies using periodic gas generated through gas deflagration can meet the impact force requirement, gas deflagration can easily ignite the powder, limiting the applicability of this method.

[0003] To address the aforementioned applicability issues, a compressed gas release method is employed to generate periodic gas. Specifically, currently, compressed gas release is achieved through an instantaneous opening valve. This valve includes a valve port and a valve stem. One end of the valve port is connected to the pipeline tower, and the other end is connected to the outlet of the gas storage tank. One end of the valve stem is inserted into the valve port, isolating the gas storage tank from the pipeline tower. When the other end of the valve stem disengages from the valve port, the gas storage tank and the pipeline tower are connected, and gas is released from the tank. Periodic gas is generated through the reciprocating motion of one end of the valve stem being inserted into the valve port and the other end disengaging from the valve port. Utility Model Content

[0004] The inventors of this utility model have discovered the following technical problems with existing instantaneous opening valves in practical applications: During the process of one end of the valve stem separating from the valve port, a gap will form between the one end of the valve stem and the inner wall of the valve port before the one end of the valve stem is completely separated from the valve port; this gap will cause the gas in the gas storage tank to leak prematurely; when one end of the valve stem is completely separated from the valve port, although the remaining gas in the gas storage tank can be released in a concentrated manner, the overall impact intensity of the gas finally released from the gas storage tank is reduced because some gas in the gas storage tank has already leaked in the early stage; as a result, the periodic gas impact force generated by the instantaneous opening valve is insufficient, so that the powder in the pipeline tower cannot be fully removed, resulting in powder residue.

[0005] In view of the above problems, this utility model is proposed to provide an instantaneous opening valve that overcomes or at least partially solves the above problems.

[0006] This utility model embodiment provides an instant-opening valve, installed inside a gas storage tank, comprising: an instant-opening valve cylinder body, one end of which is provided with a valve top cover, the valve top cover being provided with a valve outlet, and the outer and inner ends of the valve outlet being provided with a Laval tube and a hollow column, wherein the outer wall of the hollow column and the inner wall of the instant-opening valve cylinder body form a flow channel for gas flow.

[0007] The cylinder body of the instantaneous opening valve has several vent holes on the side wall near the valve outlet.

[0008] The Laval tube passes through the gas inlet of the gas storage tank and is sealed to the gas inlet.

[0009] The cylinder of the instantaneous opening valve is equipped with a piston. A valve seal is provided on the side of the piston facing the valve outlet. The valve seal is adapted to the circumferential edge of the hollow cylinder away from the valve outlet. When the valve seal and the circumferential edge of the hollow cylinder are in contact, the interior of the gas tank is isolated from the valve outlet. When the valve seal and the circumferential edge of the hollow cylinder are separated, the interior of the gas tank is connected to the valve outlet through the flow channel.

[0010] In a further optional embodiment, the hollow cylinder has a plurality of raised rings on the circumferential edge of one end near the valve seal.

[0011] In a further optional embodiment, the instantaneous opening valve includes a charge / discharge line;

[0012] The cylinder body of the instantaneous opening valve is provided with a valve bottom cover at the end away from the valve outlet. The valve bottom cover is provided with an air filling / draining hole and a one-way hole. A one-way valve is installed in the one-way hole. The one-way valve is in the direction of conduction from the inside of the instantaneous opening valve cylinder body to the inside of the air storage tank. When the pressure inside the instantaneous opening valve cylinder body reaches a first specified pressure, the one-way valve opens.

[0013] One end of the inflation / deflation pipe is connected to the inflation / deflation port, and the other end passes through the tail opening of the gas storage tank and extends outside the gas storage tank.

[0014] In a further optional embodiment, a one-way valve mounting plate is provided between the one-way hole and the one-way valve, the one-way valve mounting plate being used to fix the one-way valve and to align the one-way valve and the one-way hole coaxially.

[0015] In a further optional embodiment, the side of the valve top cover facing the inner wall of the gas storage tank is fitted and sealed to the top cover of the gas storage tank.

[0016] In a further optional embodiment, the valve seal includes a sealing gasket and a reinforcing plate, wherein the sealing gasket is fixedly connected to the reinforcing plate.

[0017] In a further alternative embodiment, the piston has piston rings on its outer side wall away from the valve top cover.

[0018] In a further alternative embodiment, the valve base cover has a removable cushioning pad on the side facing the piston.

[0019] In a further optional embodiment, the outer wall of the piston is provided with a piston seal ring.

[0020] In a further optional embodiment, a valve top cover sealing gasket is provided between the side of the valve top cover facing the inner wall of the gas storage tank and the contact surface of the gas storage tank top cover.

[0021] The beneficial effects of the above-mentioned technical solutions provided by the embodiments of this utility model include at least the following:

[0022] This invention's instantaneous opening valve utilizes a sealing ring on the side of the piston facing the valve outlet, which is adapted to the circumferential edge of the hollow cylinder away from the valve outlet. This forms a precise "fit-separation" sealing control structure. When the sealing ring fits against the circumferential edge of the hollow cylinder, it completely isolates the passage between the inside of the gas tank and the valve outlet, eliminating the problem of premature gas leakage caused by gaps when the valve stem is not completely detached from the valve port, as seen in existing technologies. Only after the sealing ring is completely separated from the circumferential edge of the hollow cylinder can the gas inside the gas tank quickly enter the valve outlet through a pre-set flow channel between the outer wall of the hollow cylinder and the inner wall of the instantaneous opening valve cylinder. This achieves concentrated and instantaneous gas release, avoiding losses caused by early gas leakage and ensuring that the gas finally released from the gas tank has sufficient impact strength. A pull-out valve is also provided on the outer end of the valve outlet. The tube accelerates the released airflow, further enhancing the gas impact effect. The vent hole on the side wall of the instant-opening valve cylinder near the valve outlet helps balance the internal pressure of the cylinder, ensuring that the piston can quickly switch from "fitting and sealing" to "separating and conducting," reducing the lag time of gas release and ensuring the instantaneity and stability of the gas impact. Ultimately, the periodic gas impact force generated by the instant-opening valve remains sufficient and stable, effectively acting on the powder in the pipeline tower. This effectively solves the problem of powder residue caused by insufficient removal in existing technologies, improving the powder removal effect in the pipeline tower. Furthermore, the overall structural design adapts to the requirements of gas flow and sealing control, further optimizing the practical performance of the instant-opening valve while ensuring sealing reliability and action response speed.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0033] To address the problems existing in the prior art, this utility model provides an instantaneous opening valve.

[0034] This embodiment of the utility model provides an instant-opening valve, installed inside the gas storage tank 20, such as... Figure 1 As shown, it includes: an instant-opening valve cylinder body 1, a valve top cover 2 at one end of the instant-opening valve cylinder body 1, a valve outlet 3 at the valve top cover 2, a Laval tube 4 and a hollow cylinder 5 at the outer and inner ends of the valve outlet 3, and a flow channel for gas flow is formed between the outer wall of the hollow cylinder 5 and the inner wall of the instant-opening valve cylinder body 1; wherein, the outer end refers to the end of the valve outlet 3 on the outside of the instant-opening valve cylinder body 1, and the inner end refers to the end of the valve outlet 3 on the inside of the instant-opening valve cylinder body 1.

[0035] The cylinder body 1 of the instantaneous opening valve has several vent holes 6 on the side wall near the valve outlet 3.

[0036] The Laval tube 4 is inserted through the gas inlet 22 of the gas storage tank 20 and is sealed to the gas inlet 22.

[0037] The cylinder body 1 of the instantaneous opening valve is equipped with a piston 7. A valve seal 8 is provided on the side of the piston 7 facing the valve outlet 3. The valve seal 8 is adapted to the circumferential edge of the hollow cylinder 5 away from the valve outlet 3. When the valve seal 8 and the circumferential edge of the hollow cylinder 5 are in contact, the distance from the edge of the vent hole 6 away from the valve top cover 2 to the end face of the valve top cover 2 facing the piston 7 is less than the distance from the end face of the valve top cover 2 facing the piston 7 to the end face of the piston 7 away from the valve top cover 2, so that the interior of the gas storage tank 20 is isolated from the valve outlet 3. When the valve seal 8 and the circumferential edge of the hollow cylinder 5 are separated, the interior of the gas storage tank 20 is connected to the valve outlet 3 through the flow channel.

[0038] In an optional embodiment, a plurality of raised rings 9 are provided on the circumferential edge of one end of the hollow cylinder 5 near the valve seal 8, and the raised rings 9 further enhance the seal between the valve seal 8 and the hollow cylinder 5; for example Figure 2 As shown, the convex ring 9 can be tilted towards the axis center or away from the axis center, and the convex ring 9 can be triangular or rhomboid.

[0039] In an optional embodiment, the diameter of the valve seal 8 is larger than the outer diameter of the hollow cylinder 5.

[0040] In an optional embodiment, the instantaneous opening valve includes a charging / discharging pipe 10; a valve bottom cover 11 is provided at the end of the instantaneous opening valve cylinder 1 away from the valve outlet 3, and the valve bottom cover 11 has a charging / discharging hole 12 and a one-way hole 13. A one-way valve 14 is installed in the one-way hole 13; the conduction direction of the one-way valve 14 is from the inside of the instantaneous opening valve cylinder 1 to the inside of the gas storage tank 20. When the pressure inside the instantaneous opening valve cylinder 1 reaches a first specified pressure, the one-way valve 14 opens; wherein the first specified pressure is set according to the instantaneous opening valve; for example, the first specified pressure is 0.05 MPa, and when the pressure inside the instantaneous opening valve cylinder 1 reaches 0.05 MPa, the one-way valve 14 opens; this embodiment is not limited to this example. One end of the charging / discharging pipe 10 is connected to the charging / discharging hole 12, and the other end passes through the tail port 23 of the gas storage tank 20 and extends out of the gas storage tank 20.

[0041] In an optional embodiment, a one-way valve mounting plate 15 is provided between the one-way hole 13 and the one-way valve 14. The one-way valve mounting plate 15 is used to fix the one-way valve 14 and make the one-way valve 14 and the one-way hole 13 coaxially aligned.

[0042] In an optional embodiment, the side of the valve top cover 2 facing the inner wall of the gas storage tank 20 is fitted and sealed to the top cover 21 of the gas storage tank 20; this further ensures the sealing between the instantaneous opening valve and the gas storage tank 20.

[0043] In an optional embodiment, the valve seal 8 includes a sealing gasket 24 and a reinforcing plate 25, with the sealing gasket 24 and the reinforcing plate 25 fixedly connected. The sealing gasket 24 can be a commonly used sealing gasket, and the reinforcing plate 25 can be a metal plate or a rigid plastic plate. The sealing gasket 24 can be fixedly connected to the reinforcing plate 25 by adhesive. The valve seal 8 is fixedly connected to the piston 7 through the reinforcing plate 25.

[0044] In an optional embodiment, a piston ring 16 is provided on the outer side wall of the piston 7 away from the valve top cover 2. The piston ring 16 further enhances the sealing between the piston 7 and the instantaneous opening valve cylinder 1. The piston ring 16 can also ensure that the piston 7 moves stably up and down in the axial direction, increasing the service life of the instantaneous opening valve. The upward movement of the piston 7 refers to the movement of the piston 7 towards the valve bottom cover 11, and the downward movement of the piston 7 refers to the movement of the piston 7 towards the valve top cover 2.

[0045] In an optional embodiment, the valve bottom cover 11 is provided with a removable buffer pad 17 on the side facing the piston 7 so that the buffer pad 17 can be replaced; the buffer pad 17 can be a conventional buffer pad; the buffer pad 17 can reduce the impact on the valve bottom cover 11 when the piston 7 moves upward, and increase the service life of the instantaneous opening valve.

[0046] In an optional embodiment, the outer wall of the piston 7 is provided with a piston sealing ring 18 to further enhance the sealing between the piston 7 and the instantaneous opening valve cylinder 1.

[0047] In an optional embodiment, a valve top cover sealing gasket 19 is provided between the side of the valve top cover 2 facing the inner wall of the gas storage tank 20 and the contact surface of the tank top cover 21 of the gas storage tank 20. The valve top cover sealing gasket 19 is used to enhance the sealing performance between the valve top cover 2 and the tank top cover 21 of the gas storage tank 20.

[0048] In this embodiment, the working process of the instantaneous opening valve is as follows: In the initial working state, the instantaneous opening valve is installed inside the gas storage tank 20. Initially, the piston 7 is located in the lower part of the cylinder body 1 of the instantaneous opening valve. The valve seal 8 on the side of the piston 7 facing the valve outlet 3 is separated from the end of the hollow cylinder 5 away from the valve outlet 3. The end of the charging and discharging pipe 10 extending outside the gas storage tank 20 is connected to an external charging and discharging device. For example, it is connected to an air compressor. This embodiment is not limited to this example. Other devices with high-pressure charging and discharging functions can also be used. Since there is no pressure inside the cylinder body 1 of the instantaneous opening valve, the one-way valve 14, which is fixed by the one-way valve mounting plate 15 and coaxially aligned with the one-way valve 13, remains closed. At the same time, there is no residual high-pressure gas inside the cylinder body 1 of the instantaneous opening valve, and the vent 6 on the side wall of the cylinder body near the valve outlet 3 remains naturally open.

[0049] During the inflation phase of the instantaneous opening valve, an external inflation / deflation device injects high-pressure gas into the cylinder 1 of the instantaneous opening valve through the inflation / deflation pipe 10. The gas enters the cylinder 1 through the inflation / deflation hole 12 of the valve bottom cover 11. Under the thrust of the high-pressure gas, the piston 7 drives the valve seal 8 to move downward along the inner wall of the cylinder 1. When the valve seal 8 moves to the designated position and is completely in contact with the end of the hollow cylinder 5 away from the valve outlet 3, and the protruding ring 9 on the edge of the hollow cylinder 5 is embedded in the sealing gasket 24 of the valve seal 8 to enhance the sealing effect, the piston 7 and the valve seal 8 stop moving. After that, the pressure inside the cylinder 1 of the instantaneous opening valve continues to increase. When the pressure rises to the first designated pressure, the one-way valve 14 opens, and the high-pressure gas inside the cylinder 1 of the instantaneous opening valve enters the gas storage tank 20 through the one-way valve 14, so that the pressure inside the gas storage tank 20 gradually increases with the injection of gas.

[0050] During the instantaneous opening valve venting phase, the pressure inside the instantaneous opening valve cylinder 1 increases to a second specified pressure. This second specified pressure is higher than the first specified pressure; the specific value is set based on actual powder removal requirements and the pressure resistance of the gas storage tank 20. The external charging / discharging equipment switches to exhaust mode, instantly discharging the high-pressure gas inside the instantaneous opening valve cylinder 1 to the outside through the charging / discharging pipe 10. The pressure inside the instantaneous opening valve cylinder 1 briefly falls below the pressure inside the gas storage tank 20, and the one-way valve 14 automatically closes. Under the pressure difference, the pressurized high-pressure gas inside the gas storage tank 20 flows through the instantaneous opening valve cylinder 1... Vent 6 enters the cylinder body, pushing valve seal 8 to drive piston 7 to move upward along the inner wall of instant-opening valve cylinder 1. When piston 7 moves upward to near valve bottom cover 11, the removable buffer pad 17 on the side of valve bottom cover 11 facing piston 7 can buffer the impact force of piston 7. As valve seal 8 and the ring edge of hollow cylinder 5 quickly separate, high-pressure gas in gas tank 20 enters valve outlet 3 through the flow channel between the outer wall of hollow cylinder 5 and the inner wall of instant-opening valve cylinder 1, and is accelerated by the Laval tube 4 at the outer end of valve outlet 3 to form an instantaneous high-speed airflow.

[0051] If periodic gas impact requirements are needed, such as the periodic removal of powder from pipeline towers, simply repeat the above-described instantaneous valve charging and venting operations.

[0052] In this embodiment, the instantaneous opening valve forms a precise "fit-separation" sealing control structure by setting a valve seal 8 on the side of the piston 7 facing the valve outlet 3, which is adapted to the circumferential edge of the hollow cylinder 5 away from the valve outlet 3. When the valve seal 8 is fitted with the circumferential edge of the hollow cylinder 5, the passage between the inside of the gas tank 20 and the valve outlet 3 can be completely cut off, eliminating the problem of premature gas leakage caused by the gap when the valve stem is not completely separated from the valve port in the prior art. When the valve seal 8 is completely separated from the circumferential edge of the hollow cylinder 5, the gas inside the gas tank 20 will quickly enter the valve outlet 3 through the pre-set flow channel between the outer wall of the hollow cylinder 5 and the inner wall of the instantaneous opening valve cylinder 1, realizing the concentrated and instantaneous release of gas, avoiding the loss caused by the gas leakage in the early stage, and ensuring that the gas finally released by the gas tank 20 has sufficient impact strength; valve outlet The Laval tube 4 located at the outer end of the valve 3 accelerates the released airflow, further enhancing the gas impact effect. The vent hole 6 located on the side wall of the cylinder 1 near the valve outlet 3 helps balance the internal pressure of the cylinder, ensuring that the piston 7 can quickly switch from "fitting and sealing" to "separating and conducting," reducing the lag time of gas release and ensuring the instantaneity and stability of the gas impact. Ultimately, the periodic gas impact force generated by the instantaneous valve remains sufficient and stable, effectively acting on the powder in the pipeline tower. This effectively solves the problem of powder residue caused by insufficient removal in existing technologies, improving the removal effect of powder in the pipeline tower. Furthermore, the overall structural design adapts to the requirements of gas flow and sealing control, further optimizing the practical performance of the instantaneous valve while ensuring sealing reliability and action response speed.
