Description

Technical Field

[0001] This utility model relates to the field of gas valves, specifically to a gas control valve with a locking function. Background Technology

[0002] Gas, as an efficient and clean energy source, has been widely used in various fields of industrial production and residential life. In order to ensure the safe and stable operation of the gas system, the performance of gas control valves, as key control and safety components, is of paramount importance. Gas control valves are mainly used to control the flow of gas in gas pipelines and are the first line of defense to ensure the safety of users' gas consumption.

[0003] In practical applications, especially in complex and variable environments such as residential buildings and commercial spaces, gas control valves may face various safety risks. For example, children may accidentally operate the valve handle out of curiosity, leading to unplanned gas activation and causing gas leaks. Or, if left unattended, the valve may be accidentally bumped or touched and opened, creating a safety hazard. Utility Model Content

[0004] The purpose of this utility model is to provide a gas control valve with a locking function, which solves certain limitations in the use of existing gas control valves.

[0005] The present invention achieves the above-mentioned objective through the following technical solution: a gas control valve with locking function, comprising: a valve body and a switch handle disposed on the valve body, wherein a bracket is provided on the valve body, and a limiting member for limiting the rotation of the switch handle is movably disposed on the bracket.

[0006] Preferably, the limiting member is slidably disposed on the bracket, and an elastic member is provided between the limiting member and the bracket.

[0007] Preferably, the side wall of the limiting member is provided with a limiting groove, and the bracket is slidably provided with a limiting plate for insertion into the limiting groove.

[0008] Preferably, the limiting plate is provided with a flexible connector for connecting with the limiting member, the flexible connector being used to pull the limiting member to move when the limiting plate moves.

[0009] Preferably, a limiting block is slidably provided on the limiting plate.

[0010] Preferably, the limiting member includes a support plate and two clamping plates respectively disposed on both sides of the support plate, and the switch handle is located between the two clamping plates.

[0011] Preferably, the sidewalls of the two clamps facing the switch handle and close to each other are inclined.

[0012] Preferably, the bracket is detachably mounted on the valve body.

[0013] The beneficial effects of this utility model are as follows: 1. By limiting the rotation of the switch handle through the limiting component, the valve is prevented from being opened or closed accidentally due to accidental contact, child misoperation, or external impact. This significantly improves the safety of gas control valves during use and avoids potential safety hazards such as gas leaks caused by accidental triggering. 2. The limiting component is equipped with a limiting plate that cooperates with it. When the limiting plate is embedded in the limiting groove, it effectively constrains the limiting component, preventing it from moving or disengaging in an unauthorized state. This enhances the locking reliability of the switch handle, ensures a stable and secure locking state, and improves the overall locking mechanism's ability to prevent damage and accidental operation. 3. When it is necessary to release the locked state, simply move the limit plate to disengage it from the limit groove. During the movement of the limit plate, the limit component is driven to move synchronously through the flexible connector, so that it exits the position that restricts the switch handle. This linkage design realizes the convenient release of the locked state without the need for additional operation of the limit component, which simplifies the opening process and improves the convenience of user operation.

[0016] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0017] Example 1

[0018] Please see Figure 1A gas control valve with a locking function includes: a valve body 1, a switch handle 2 installed on the valve body 1, the switch handle 2 being used to control the opening or closing of the valve body 1, a bracket 3 installed on the valve body 1, a limiting member 4 movably provided on the bracket 3, the limiting member 4 being used to restrict the rotation of the switch handle 2 so as to lock the switch handle 2 and prevent it from being accidentally touched and opening the valve body 1.

[0019] In this embodiment, as a further optimization, please refer to... Figure 1 and Figure 3 The limiting member 4 is slidably mounted on the bracket 3. The limiting member 4 can move up or down on the bracket 3. An elastic member 9 (such as a spring) is provided between the limiting member 4 and the bracket 3. The elastic member 9 provides support for the limiting member 4, so that the limiting member 4 will not move easily, and ensures that the limiting member 4 restricts the switch handle 2 more stably.

[0020] In this embodiment, as a further optimization, please refer to... Figure 1 and Figure 2 A limiting groove 7 is provided on the side wall of the limiting component 4, and a limiting plate 5 is slidably provided on the bracket 3. The limiting plate 5 is inserted into the inner cavity of the limiting groove 7 to limit the limiting component 4 so that it will not move automatically, thereby increasing the stability of locking the switch handle and ensuring the safety of using the gas control valve.

[0021] In this embodiment, as a further optimization, please refer to... Figure 1 and Figure 2 The limiting plate 5 is provided with a flexible connector 8 (rope, but not limited to a rope), and the bracket 3 is provided with a guide hole. The end of the flexible connector 8 away from the limiting plate 5 passes through the guide hole and connects to the limiting member 4. When the limiting plate 5 is moved and removed from the limiting groove 7 to release the restriction on the limiting member 4, the flexible connector 8 will pull the limiting member 4 downward, so that the restriction of the limiting member 4 on the switch handle 2 is released. This makes it more convenient to release the restriction on the switch handle 2 by manually moving the limiting plate 5 separately.

[0022] It should be noted that a spring is installed between the limiting plate 5 and the bracket 3. The spring provides support to the limiting plate 5, preventing it from moving easily.

[0023] In this embodiment, as a further optimization, please refer to... Figure 1A limiting block 6 is slidably provided on the side wall of the limiting plate 5. The limiting block 6 can move up or down. When the limiting plate 5 moves and the limiting member 4 moves with it, after the limiting block 6 no longer contacts the top of the bracket 3, the limiting block 6 will move down and fit against the side wall of the bracket 3 to restrict the reverse movement of the limiting plate 5, thereby fixing the position of the limiting member 4. This makes it unnecessary to manually fix the limiting member 4 when the switch handle 2 is turned to open or close, making the locking function on the gas control valve more convenient to use.

[0024] In this embodiment, as a further optimization, please refer to... Figure 1 and Figure 3 The limiting member 4 includes a support plate 401 and two clamping plates 402 respectively disposed on both sides of the support plate 401. The switch handle 2 is located between the two clamping plates 402, ensuring that the switch handle 2 cannot rotate when the limiting member 4 restricts it, thereby increasing the stability of the locking. The side walls of the two clamping plates 402 facing the switch handle 2 and close to each other are inclined. The distance between the tops of the two clamping plates 402 is greater than the distance between the middle and lower parts of the two clamping plates 402, so that when the limiting member 4 moves upward, the two clamping plates 402 can easily move to both sides of the switch handle 2.

[0025] It should be noted that the distance between the lower parts of the two clamping plates 402 is equal to the width of the switch handle 2, ensuring that the switch handle 2 cannot rotate when it is between the two clamping plates 402.

[0026] In this embodiment, as a further optimization, please refer to... Figure 1 The bracket 3 is fixedly installed on the valve body 1 by bolts, so that the bracket 3 can be removed from the valve body 1.

[0027] The above-described embodiments are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
