Description

Technical Field

[0001] This utility model relates to the field of gas valve technology, and in particular to an emergency shut-off valve with a detachable actuator. Background Technology

[0002] Emergency shut-off valves are required in pipelines such as those for natural gas. A commonly used emergency shut-off valve typically consists of a valve body, actuator, and reset cap. Most conventional products use screws to fix the actuator to the valve body, which affects installation efficiency. This type of structure generally lacks a valve cover, and leaks occur after disassembling the actuator. Furthermore, the lower end of the reset cap faces the upper end of the actuator in existing emergency shut-off valves, creating a gap at the connection point. This gap allows impurities to enter during use, affecting the normal operation of the emergency shut-off valve. Summary of the Invention

[0003] The purpose of this invention is to provide an emergency shut-off valve with a detachable actuator to solve the above-mentioned problems.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: an emergency shut-off valve with a detachable actuator includes a valve body and a valve cover connected to each other. An actuator is also provided on the valve body, and a reset cap is provided on the actuator. At least two buckles are provided on the lower outer side of the actuator. An annular inner groove is provided on the outer side of the valve cover, and an opening matching the buckles is provided at the upper end of the annular inner groove, which facilitates the installation and disassembly of the actuator without damaging the components. A groove matching the buckles is provided at the part of the valve cover that connects to the actuator. The valve cover is riveted to the valve body.

[0005] The actuator of the emergency shut-off valve of this utility model is engaged with the valve cover through a snap-fit ​​and slot engagement, and the valve cover is riveted to the valve body, thereby facilitating the disassembly of the actuator during construction and installation and improving construction efficiency.

[0006] As a preferred technical solution, there are two buckles.

[0007] As a further preferred technical solution, the two buckles are symmetrically distributed.

[0008] As a preferred technical solution, the reset cap is sleeved on the upper outer side of the actuator, and the lower end face of the reset cap is lower than the upper end face of the actuator. This effectively prevents impurities from entering.

[0009] As a preferred technical solution, the valve cover is integrally fitted inside the lower end of the actuator. This arrangement allows the valve cover to be completely concealed within the actuator, resulting in better aesthetics and protection.

[0010] Compared with the prior art, the advantages of this utility model are as follows: the actuator of the emergency shut-off valve of this utility model is engaged with the valve cover through a snap-fit ​​and slot engagement, and the valve cover is riveted to the valve body, which facilitates the disassembly of the actuator during construction and installation, thereby improving construction efficiency; this utility model can also prevent impurities from entering during installation and use, ensuring the reliability and aesthetics of the emergency shut-off valve.

[0013] The present invention will be further described below with reference to the embodiments.

[0014] Example:

[0015] See Figure 1 An emergency shut-off valve with a detachable actuator includes a valve body 1 and a valve cover 2 connected to each other. A valve disc 3 is disposed inside the valve cover 2. A diaphragm 4 is disposed between the valve body 1 and the valve disc 3. A diaphragm pull rod 5 is disposed on the diaphragm 4, extending to the outside of the upper end of the valve cover 2. A spring 6 is also disposed inside the valve cover 2.

[0016] The valve body 1 is also provided with an actuator 9. The lower part and the upper part of the actuator 9 are respectively provided with a moving iron core 7 and a stationary iron core 8. A reset rod 10 is also provided. The reset rod 10 passes through the stationary iron core 8 from top to bottom and extends into the upper part of the moving iron core 7. A reset cap 11 is provided on the actuator 9. A dust cap 12 is also provided above the reset cap 11. A power cord 13 is also provided on one side of the actuator 9.

[0017] In this embodiment, two symmetrically distributed buckles 91 are provided on the lower outer side of the actuator 9. An annular inner groove is provided on the outer side of the valve cover 2. The upper end of the annular inner groove has two openings that match the buckles 91. During installation, the buckles 91 of the actuator 9 are first inserted through the openings and then locked in the annular inner groove, so that the actuator 9 can rotate 360° within the annular inner groove. The structure of the buckles, openings, and inner groove facilitates the installation and disassembly of the actuator without damaging any components. The valve cover is riveted to the valve body.

[0018] A groove matching the buckle is provided at the part of the valve cover 2 that connects to the actuator 9; the valve cover 2 is riveted to the valve body 1;

[0019] In this embodiment, the reset cap 11 is sleeved on the upper outer side of the actuator 9, and the lower end face of the reset cap 11 is lower than the upper end face of the actuator 9;

[0020] In this embodiment, the valve cover 2 is integrally fitted onto the inner side of the lower end of the actuator 9.

[0021] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
