Description

Technical Field

[0001] This utility model relates to the field of valves, specifically to a convenient dry powder valve that is easy to disassemble and replace. Background Technology

[0002] Dry powder fire extinguishers are a type of fire extinguisher widely used in firefighting. When dry powder falls onto the surface of combustible materials, it undergoes a chemical reaction and forms a glassy coating layer under high temperature. This coating layer can isolate oxygen, thereby extinguishing the fire by asphyxiation. Valves are key components in dry powder fire extinguishing systems and related industrial control equipment. Dry powder valves are the core components that control the spraying of dry powder extinguishing agents.

[0003] The existing dry powder valves still have some problems in use: Most of the existing dry powder valves are connected to the fire extinguisher tank by threads, which requires turning the entire dry powder valve to rotate and thus install the dry powder valve to the fire extinguisher tank. The body of the dry powder valve is irregularly shaped, which makes it inconvenient to turn the dry powder valve and thus affects the installation operation of the dry powder valve and the fire extinguisher tank.

[0004] Therefore, it is necessary to invent a convenient dry powder valve that is easy to disassemble and replace to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide a convenient dry powder valve that is easy to disassemble and replace, in order to solve the problem mentioned in the background art that most existing dry powder valves are connected to the fire extinguisher tank by threads. This requires turning the entire dry powder valve to achieve rotation, thereby realizing the installation of the dry powder valve and the fire extinguisher tank. The body of the dry powder valve is irregularly shaped, which makes it inconvenient to turn the dry powder valve and thus affects the installation operation of the dry powder valve and the fire extinguisher tank.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a convenient dry powder valve that is easy to disassemble and replace, comprising a valve body, a tank being movably installed at the lower end of the valve body, an extension tube being provided at both the lower end of the valve body and the top end of the tank, a second sealing ring being fixedly installed at the lower end of the tube of the lower valve body, and a first sealing ring being fixedly installed at the top end of the tube of the top of the tank, wherein the first and second sealing rings are fitted together, a positioning post being fixedly installed at the top of the first sealing ring, the positioning post matching a positioning hole pre-reserved inside the second sealing ring, threads being provided on the outer wall of the tube at the lower end of the valve body and the outer wall of the tube at the top of the tank, and the tube at the lower end of the valve body and the tube at the top of the tank being movably installed through an installation assembly.

[0007] Preferably, two positioning posts are provided, and the two positioning posts are symmetrically arranged with reference to the central axis of the sealing ring one. The height of the positioning post is less than the height of the sealing ring two. In this way, the pipe at the lower end of the valve body and the pipe at the top of the tank can be matched and connected, which facilitates the subsequent installation of the pipe at the lower end of the valve body and the pipe at the top of the tank through the installation assembly.

[0008] Preferably, the installation assembly includes a threaded sleeve pre-installed on the outer wall of the pipe body at the lower end of the valve body and on the outer wall of the pipe body at the top of the tank body, which is threadedly connected to the threaded sleeve. The outer ring of the threaded sleeve is provided with serrations to facilitate subsequent rotation of the threaded sleeve.

[0009] Preferably, the mounting assembly further includes an annular groove pre-set inside the threaded sleeve, an annular block rotatably mounted inside the annular groove, and a limiting block fixedly connected to the inner wall of the annular block and a limiting groove reserved inside the lower end of the valve body to achieve movable matching, ensuring that the threaded sleeve and the lower end of the valve body are not disconnected.

[0010] Preferably, the threaded groove of the inner ring of the threaded sleeve can be threadedly connected to the thread of the outer ring of the extended tube provided at the lower end of the valve body and the top of the tank body, thus ensuring a firm threaded connection between the tube at the lower end of the valve body and the tube at the top of the tank body and the threaded sleeve.

[0011] Preferably, there are two limiting blocks, and the two limiting blocks are symmetrically arranged with reference to the central axis of the annular block as the axis of symmetry. The outer wall of the limiting block is in contact with the inner wall of the limiting groove to achieve a sliding connection, so as to ensure that when the threaded sleeve rotates and changes its position and height, the limiting block will not affect the movement of the threaded sleeve.

[0012] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0013] 1. This utility model enables the lower end of the valve body and the upper end of the tank to be matched and connected by the positioning pin and the positioning hole reserved inside the sealing ring. This facilitates the subsequent installation of the lower end of the valve body and the upper end of the tank through the installation components, without the need to rotate the valve body, thus ensuring easy rotation and installation.

[0014] 2. As the threaded sleeve, which is threadedly connected to the lower end of the valve body and the upper end of the tank, rotates, its position and height change simultaneously. This causes the annular block and the limiting block, which is fixedly connected to the inner wall of the annular block, to move within the limiting groove. When the limiting block abuts against the upper and lower end walls of the limiting groove, it indicates that the threaded sleeve has moved to its limit position. The limiting groove is located in the lower end of the valve body. This ensures that the threaded sleeve will not detach from the lower end of the valve body when the threaded sleeve is turned to achieve a threaded connection with the upper end of the tank.

[0022] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0023] This utility model provides, for example Figure 1-4The present invention discloses a convenient dry powder valve that is easy to disassemble and replace, comprising a valve body 1, a tank 2 movably mounted at the lower end of the valve body 1, an extension tube provided at the lower end of the valve body 1 and the top end of the tank 2, a sealing ring 2 4 fixedly mounted at the lower end of the tube at the lower end of the valve body 1, and a sealing ring 3 fixedly mounted at the top end of the tube at the top of the tank 2, wherein the sealing ring 3 and the sealing ring 2 4 are fitted together, and a positioning post 5 is fixedly mounted at the top of the sealing ring 3, the positioning post 5 matching the positioning hole reserved inside the sealing ring 2 4, threads provided on the outer wall of the tube at the lower end of the valve body 1 and the outer wall of the tube at the top of the tank 2, and the tube at the lower end of the valve body 1 and the tube at the top of the tank 2 are movably mounted through an installation component 6.

[0024] In this way, the positioning pin 5 and the positioning hole reserved inside the sealing ring 4 can achieve a limit matching connection between the lower end of the valve body 1 and the upper end of the tank body 2. This makes it convenient for the lower end of the valve body 1 and the upper end of the tank body 2 to be installed through the installation component 6 without having to rotate the valve body 1, ensuring easy rotation and installation.

[0025] To ensure the limited installation of the valve body 1 and the tank body 2, two positioning posts 5 are provided. The two positioning posts 5 are symmetrically arranged with reference to the central axis of the sealing ring 3. The height of the positioning posts 5 is smaller than the height of the sealing ring 4. In this way, the pipe at the lower end of the valve body 1 and the pipe at the top of the tank body 2 can be matched and connected in a limited manner, which facilitates the subsequent installation of the pipe at the lower end of the valve body 1 and the pipe at the top of the tank body 2 through the installation component 6.

[0026] To facilitate the connection and installation of the pipe at the lower end of the valve body 1 and the pipe at the top of the tank body 2, the installation component 6 includes a threaded sleeve 601 pre-installed on the outer wall of the pipe at the lower end of the valve body 1 and the outer wall of the pipe at the top of the tank body 2, which is threadedly connected to the threaded sleeve. The installation component 6 also includes an annular groove 603 pre-installed inside the threaded sleeve 601. An annular block 604 is rotatably installed inside the annular groove 603. A limiting block 605 fixedly connected to the inner wall of the annular block 604 is movably matched with a limiting groove 606 reserved inside the pipe at the lower end of the valve body 1, ensuring that the threaded sleeve 601 and the pipe at the lower end of the valve body 1 are not disconnected. The outer ring of the threaded sleeve 601 is provided with serrations 602.

[0027] To facilitate the subsequent rotation of the threaded sleeve 601, the threaded sleeve 601, which is threaded to the lower end of the valve body 1 and the outer wall of the top of the tank body 2, changes its position and height during rotation. This causes the threaded sleeve 601, which was originally threaded to the lower end of the valve body 1, to move and achieve a threaded connection with the top of the tank body 2, thereby completing the connection between the lower end of the valve body 1 and the top of the tank body 2.

[0028] The threaded groove on the inner ring of the threaded sleeve 601 can be threadedly connected to the threaded outer ring of the extended tube body provided at the lower end of the valve body 1 and the top of the tank body 2. This ensures a firm threaded connection between the tube body at the lower end of the valve body 1 and the tube body at the top of the tank body 2 and the threaded sleeve 601.

[0029] Two limit blocks 605 are provided, and the two limit blocks 605 are symmetrically arranged with reference to the central axis of the annular block 604. The outer wall of the limit block 605 is attached to the inner wall of the limit groove 606 to achieve a sliding connection, ensuring that when the threaded sleeve 601 rotates and changes its position and height, the limit block 605 will not affect the movement of the threaded sleeve 601.

[0030] Simultaneously, the threaded sleeve 601, which is threadedly connected to the lower end of the valve body 1 and the top end of the tank body 2, rotates and its position changes. This synchronously drives the annular block 604 and the limiting block 605, which is fixedly connected to the inner wall of the annular block 604, to move inside the limiting groove 606. When the limiting block 605 abuts against the upper and lower end walls of the limiting groove 606, it indicates that the threaded sleeve 601 has moved to its limit position. The limiting groove 606 is located inside the lower end of the valve body 1. In this way, when the threaded sleeve 601 is turned to connect with the top end of the tank body 2, the threaded sleeve 601 will not fall off the lower end of the valve body 1.

[0031] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
