Description

Technical Field

[0001] This utility model relates to the technical field of cylinder valves, specifically a cylinder valve with a linkage shut-off function. Background Technology

[0002] A cylinder valve is a special valve installed on a steel cylinder to control the opening and closing of the gas passage. The cylinder valve outlet is usually equipped with a self-closing device, which ensures that the gas passage opens only when the cylinder valve handwheel and the self-closing device are opened simultaneously, primarily serving a secondary protection function. However, the self-closing device of existing cylinder valves activates when its associated products (such as pressure regulators) are installed.

[0003] To prevent gas leakage, an independent safety shut-off device is usually installed outside the cylinder valve. For example, a robotic arm can be installed to control the cylinder valve handwheel. The robotic arm controls the cylinder valve handwheel, thereby controlling the opening and closing of the gas passage of the cylinder valve. Alternatively, a shut-off valve can be installed at the rear end of the cylinder valve outlet (this shut-off valve is an independent structure or integrated into the pressure regulator). The shut-off valve controls the opening and closing of the gas passage.

[0004] However, after the robotic arm controls the cylinder valve handwheel, it will change the closing or opening torque of the cylinder handwheel. On the other hand, excessive torque may cause the cylinder valve handwheel to fail to close in critical situations. Due to the influence of the robotic arm, it will cause inconvenience in filling and replacing cylinders. When a shut-off valve is installed at the rear end of the cylinder valve outlet, since the shut-off valve is located at the rear end of the cylinder valve outlet, there is no effective safety protection measure when a gas leak occurs between the cylinder valve and the shut-off valve. Utility Model Content

[0005] The purpose of this utility model is to provide a bottle valve with a linkage shut-off function to solve the technical problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A bottle valve with a linkage shut-off function includes: a bottle valve body;

[0008] A self-closing mechanism is provided inside the bottle valve body; the self-closing mechanism is independently arranged in the channel of the bottle valve body and is used to automatically seal the self-closing valve of the bottle valve body.

[0009] An opening mechanism is provided at the self-closing valve port. The opening mechanism is sealed to the self-closing valve port and is linked to the self-closing mechanism. It is used to drive the opening mechanism to move by external force, thereby driving the self-closing mechanism to open the self-closing valve port.

[0010] Optionally, the bottle valve body further includes a bottle valve handwheel, which is disposed on the bottle valve body and used to open or close the bottle valve body; the bottle valve handwheel is independently disposed from the self-closing mechanism.

[0011] Optionally, the self-closing mechanism includes: a driving component and a sealing assembly;

[0012] One end of the driving component is disposed in the body of the bottle valve, and the other end is connected to the sealing assembly; the sealing assembly is slidably disposed in the channel of the bottle valve body, and is used to move toward the self-closing valve port under the drive of the driving component, so as to automatically seal the self-closing valve port of the bottle valve body.

[0013] Optionally, the driving component is a spring; the sealing assembly includes: a valve gasket, a guide sleeve, and a self-closing rod;

[0014] The guide sleeve is disposed within the channel of the bottle valve body, and the self-closing rod is inserted inside the guide sleeve and slidably engaged with the guide sleeve; one end of the driving member is connected to the guide sleeve, and the other end is connected to the self-closing rod; the valve pad is disposed on the self-closing rod, and the driving member drives the self-closing rod to abut against the self-closing valve port under the limiting position of the guide sleeve, and the valve pad is squeezed and sealed with the self-closing valve port.

[0015] Optionally, the end of the self-closing rod passes through the self-closing valve port and extends to the outside of the self-closing valve port for linkage with the opening mechanism.

[0016] Optionally, the opening mechanism includes: a sealing ring and a guide drive assembly;

[0017] The sealing ring is connected to the guide drive assembly, and the guide drive assembly is sealed to the self-closing valve port. After the guide drive assembly is connected to the self-closing valve port, the sealing ring is squeezed and sealed to the self-closing valve port. The guide drive assembly can drive the self-closing mechanism to open the self-closing valve port by applying force to the self-closing mechanism.

[0018] Optionally, the guide drive assembly includes: a connector, a handwheel, and an opening / closing lever;

[0019] The sealing ring is disposed on the connector; the handwheel is sleeved and fixed on the outside of the connector; the opening and closing rod is inserted into the inside of the connector and slides with the connector; the end of the opening and closing rod is used to apply external force to the self-closing mechanism; the handwheel is connected to the gas outlet end of the bottle valve body.

[0020] Optionally, the handwheel is threadedly connected to the outlet end of the bottle valve body.

[0021] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model provides a bottle valve with a linkage shut-off function, including: a bottle valve body; a self-closing mechanism is provided in the bottle valve body; the self-closing mechanism is independently provided in the channel of the bottle valve body for automatically sealing the self-closing valve port of the bottle valve body; an opening mechanism is provided at the self-closing valve port, the opening mechanism is sealed to the self-closing valve port, and the opening mechanism is linked to the self-closing mechanism for driving the opening mechanism to move by external force to drive the self-closing mechanism to open the self-closing valve port. The self-closing mechanism of the cylinder valve is linked to the opening mechanism at the rear end of the gas outlet of the cylinder valve body. When there is no gas supply, the self-closing mechanism automatically closes the gas outlet of the cylinder valve body, and is not affected by the opening or closing of the cylinder valve handwheel itself. The two are set independently, which can improve gas safety. It eliminates the need for an independent safety shut-off device installed outside the cylinder valve, and avoids changes in the closing or opening torque of the cylinder handwheel, thus improving safety. The opening and closing of the self-closing mechanism of the cylinder valve is controlled by the rear opening mechanism. When a gas leak occurs at the gas outlet of the cylinder valve, only the opening mechanism needs to be removed. This avoids the problem in the prior art where there is no effective safety protection measure when a gas leak occurs between the cylinder valve and the shut-off valve, thus making the cylinder valve with linkage shut-off function provided in this application more convenient and safer.

[0026] Various exemplary embodiments, features, and aspects of this application will now be described in detail with reference to the accompanying drawings. The same reference numerals in the drawings denote elements that have the same or similar functions. Although various aspects of the embodiments are shown in the drawings, they are not necessarily drawn to scale unless specifically indicated otherwise.

[0027] The term “exemplary” as used herein means “serving as an example, embodiment, or illustration.” Any embodiment illustrated herein as “exemplary” is not necessarily to be construed as superior to or better than other embodiments.

[0028] Furthermore, to better illustrate this application, numerous specific details are provided in the following detailed embodiments. Those skilled in the art should understand that this application can be implemented without certain specific details. In some instances, methods, means, and elements well-known to those skilled in the art have not been described in detail in order to highlight the main points of this application.

[0029] Please see Figure 1-3 In this embodiment of the present invention, a bottle valve with a linkage shut-off function includes: a bottle valve body 1; a self-closing mechanism is provided inside the bottle valve body 1; the self-closing mechanism is independently provided in the channel of the bottle valve body 1 for automatically sealing the self-closing valve port 2 of the bottle valve body 1; an opening mechanism 7 is provided at the self-closing valve port 2, the opening mechanism 7 is sealed to the self-closing valve port 2, and the opening mechanism 7 is linked to the self-closing mechanism for driving the opening mechanism 7 to move by external force to drive the self-closing mechanism to open the self-closing valve port 2.

[0030] In this embodiment, the cylinder valve provided by this application is mainly used on bottled liquefied petroleum gas cylinders. Of course, it can also be installed on other types of cylinders, and this application does not limit it.

[0031] In this embodiment, the opening mechanism 7 provided in this application can be opened in various ways. For example, it can be a pressure reducing valve, with a driving source, such as an electric push rod or motor assembly, etc., inside the pressure reducing valve. Alternatively, it can be a manual push rod, which is used to manually push the push rod to drive the opening mechanism 7 to move, thereby driving the self-closing mechanism to move and opening the air outlet of the bottle valve body 1. Or it can be other structures that can drive the opening mechanism 7 to move. This application does not limit it. In this application, as long as an external force can be provided to drive the opening mechanism 7 toward the self-closing mechanism, the air outlet of the bottle valve body 1 in this application can be opened.

[0032] In one specific embodiment, the bottle valve body 1 further includes a bottle valve handwheel, which is disposed on the bottle valve body 1 and used to open or close the bottle valve body 1; the bottle valve handwheel is independently disposed from the self-closing mechanism. The aforementioned bottle valve handwheel is an integral structure of the bottle valve body 1, used to open or close the bottle valve body 1.

[0033] In one specific embodiment, the self-closing mechanism includes: a driving member and a sealing assembly; one end of the driving member is disposed inside the bottle valve body 1, and the other end is connected to the sealing assembly; the sealing assembly is slidably disposed in the channel of the bottle valve body 1, and is used to move toward the self-closing valve port 2 under the drive of the driving member, so as to automatically seal the self-closing valve port 2 of the bottle valve body 1.

[0034] In this embodiment, the driving component is a spring 6; the sealing assembly includes: a valve pad 4, a guide sleeve 5, and a self-closing rod 3; the guide sleeve 5 is disposed in the channel of the bottle valve body 1, and the self-closing rod 3 is inserted inside the guide sleeve 5 and slides with the guide sleeve 5; one end of the driving component is connected to the guide sleeve 5, and the other end is connected to the self-closing rod 3; the valve pad 4 is disposed on the self-closing rod 3, and the driving component drives the self-closing rod 3 to abut against the self-closing valve port 2 under the limiting position of the guide sleeve 5, and the valve pad 4 and the self-closing valve port 2 are squeezed and sealed.

[0035] In one specific embodiment, the end of the self-closing rod 3 passes through the self-closing valve port 2 and extends to the outside of the self-closing valve port 2 for linkage with the opening mechanism 7.

[0036] In this embodiment, the opening mechanism 7 includes: a sealing ring 7-1 and a guide drive assembly; the sealing ring 7-1 is connected to the guide drive assembly, and the guide drive assembly is sealed to the self-closing valve port 2; after the guide drive assembly is connected to the self-closing valve port 2, the sealing ring 7-1 is squeezed and sealed to the self-closing valve port 2; the guide drive assembly can drive the self-closing mechanism to open the self-closing valve port 2 by applying force to the self-closing mechanism.

[0037] Furthermore, such as Figure 3 As shown, the guide drive assembly includes: a connector 7-2, a handwheel 7-3, and an opening / closing lever 7-4; the sealing ring 7-1 is disposed on the connector 7-2; the handwheel 7-3 is sleeved and fixed on the outside of the connector 7-2; the opening / closing lever 7-4 is inserted into the inside of the connector 7-2 and slides with the connector 7-2; the end of the opening / closing lever 7-4 is used to apply external force to the self-closing mechanism; the handwheel 7-3 is connected to the gas outlet end of the bottle valve body 1.

[0038] In one specific embodiment, the handwheel 7-3 is threadedly connected to the outlet end of the bottle valve body 1. Using a threaded connection improves the connection stability between the handwheel 7-3 and the bottle valve body 1.

[0039] In this embodiment, see Figure 1As shown, when the opening mechanism 7 is threadedly connected and installed on the bottle valve body 1, the rear end wall of the self-closing valve port 2 of the bottle valve body 1 presses against the sealing ring 7-1 on the opening mechanism 7, thus sealing the self-closing valve port 2. When no external force is applied to the opening mechanism 7, there is a gap between the opening / closing rod 7-4 and the self-closing rod 3 in the opening mechanism 7, and the two do not contact each other. At this time, the self-closing rod 3 and the valve pad 4 are pressed and sealed against the self-closing valve port 2 under the action of the spring 6. Specifically, the valve pad 4 set on the self-closing rod 3 is pressed and sealed against the self-closing valve port 2 under the action of the spring 6 and the self-closing rod 3. The self-closing valve port 2 is fixed to the bottle valve body 1 by threads. At this time, the self-closing device is in the linkage cut-off state. Since the self-closing mechanism and the bottle valve handwheel are set independently, the self-closing valve port 2 of the bottle valve body 1 is always in the closed state regardless of whether the bottle valve handwheel is opened or closed.

[0040] like Figure 2 As shown, when it is necessary to open the self-closing valve port 2 of the bottle valve body 1, an external force is applied to the opening mechanism 7. At this time, the opening and closing rod 7-4 on the opening mechanism 7 moves to the left under the action of the external force, pushing the self-closing rod 3 to move to the left, thereby causing the valve pad 4 to disengage from the self-closing valve port 2, and the passage of the self-closing valve port 2 is opened. When it is necessary to close the passage of the self-closing valve port 2 of the bottle valve body, the external force applied to the opening mechanism 7 is released, causing the opening and closing rod 7-4 on the opening mechanism 7 to move to the right. The self-closing rod 3 moves to the right under the action of the spring 6 until the self-closing rod 3 separates from the opening and closing rod 7-4. Under the squeezing action of the spring 6 and the self-closing rod 3, the valve pad 4 seals against the self-closing valve port 2 of the bottle valve body 1, and the passage of the self-closing valve port 2 of the bottle valve body 1 is closed.

[0041] As can be seen, by adopting the solution of this application and independently designing the self-closing mechanism of the valve body 1, the function of automatically closing the self-closing valve port 2 of the valve body 1 is not affected by the valve handwheel. Regardless of whether the valve handwheel is open or closed, the valve with the linkage cut-off function provided by this application is always in the closed state, which improves the safety of the valve. In addition, the self-closing mechanism of the valve body 1 is linked with the opening mechanism 7 at the rear end of the gas outlet of the valve body 1. The opening and closing of the self-closing mechanism of the valve is controlled by the opening mechanism 7 at the rear end. That is, when the user uses gas, he / she can open the gas supply through the opening mechanism 7, and when the user does not use gas, he / she can automatically close the valve body 1 through the opening mechanism 7, which further improves the safety of gas use.

[0042] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.

This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
