Description

Technical Field

[0001] The utility model relates to the technical field of fire valves, in particular to a water leakage-proof fire valve. Background Art

[0002] In fire protection systems, valves are key control components, and their performance and reliability are crucial to the safe operation of the entire system. However, in practice, fire protection valves are prone to leaks at their joints after prolonged use or exposure to external shocks. This not only wastes water resources but, more importantly, in emergency situations, leaking fire protection valves can severely impact firefighting efficiency and even pose a threat to human life and property.

[0003] Traditional fire valves typically use simple connection methods at their joints, such as threaded or flanged connections. These connection methods often meet basic sealing requirements during installation and initial use. However, over time, due to factors such as material aging, temperature changes, and vibration, the sealing performance of the joints will gradually deteriorate, leading to water leakage. Utility Model Content

[0004] (1) Purpose of the utility model

[0005] In view of this, the purpose of the present invention is to provide a water-leakage-proof fire valve to solve the problems raised in the above background.

[0006] (2) Technical solution

[0007] A water-leakage-proof fire valve comprises a fire valve body, a connecting pipe is connected to one side of the fire valve body, and a clamping ring is connected to one end of the connecting pipe, a connecting ring is fixedly installed on the inner wall of the clamping ring, and a limiting ring is connected to one end of the connecting ring, an abutting pipe is movably installed between the clamping ring and the limiting ring, and a limiting plate is fixedly installed on one side of the abutting pipe, one end of the limiting plate is connected to a water pipe, the outer surface of the clamping ring is provided with threads and multiple groups of vertical through grooves, and an extrusion tube is movably installed on the outer surface of the clamping ring.

[0008] Preferably, multiple sets of operating rods are fixedly installed on the outer surface of the extrusion tube, and one end of the multiple sets of operating rods is arc-shaped, so that the operator feels better when rotating and it is easier to apply force, thereby improving the efficiency of installation and disassembly.

[0009] Preferably, an airbag is installed on the inner wall of the clamping ring, which can fill the tiny gap between the abutment tube and the clamping ring when the clamping ring contracts, thereby enhancing the sealing effect, effectively preventing water or liquid leakage, and improving the reliability of the entire fire valve system.

[0010] Preferably, one end of the abutting tube is in an arc shape, and the outer surface of the abutting tube is wrapped with rubber. The arc shape of one end of the abutting tube makes the contact with the clamping ring and the limit ring more uniform, reduces the stress concentration point, and thus extends the service life. At the same time, the outer surface of the abutting tube is wrapped with rubber, which increases the friction between the clamping ring and the clamping ring, making the connection more stable, and the rubber material can also provide a certain elasticity, which helps to seal.

[0011] Preferably, a snap-fit ​​groove is provided on one side of the limit plate, and the snap-fit ​​groove is wrapped with rubber. The snap-fit ​​groove makes the connection between the extrusion tube and the limit plate more stable and not easy to fall off, and the elasticity of the rubber can also provide a certain sealing effect to prevent water or liquid leakage.

[0012] Preferably, one end of the extruded tube is conical, so that during the rotation, the bottom of the cone can gradually squeeze the clamping ring, thereby achieving tight clamping of the abutting tube.

[0013] Preferably, the connecting ring is made of a magnetic material, so that when the abutting tube is inserted, the connecting ring can immediately adsorb the abutting tube, thereby ensuring its stability in the initial position.

[0014] It can be seen from the above technical solutions that this application has the following beneficial effects:

[0015] 1. This utility model rotates the squeeze tube, utilizing the conical design at one end to gradually squeeze the clamping ring, causing it to contract along the thread direction and tightly clamp the abutting tube. This mechanism ensures a secure and leak-proof connection, effectively preventing water or liquid leakage. Furthermore, the airbag installed in the vertical groove inside the clamping ring deforms when squeezed, filling the tiny gap between the abutting tube and the clamping ring. This design significantly enhances the sealing effect and further improves the overall waterproof and leak-proof performance.

[0016] 2. The entire installation and connection process of this utility model is designed to be very intuitive and simple. The operator only needs to rotate the squeeze tube to complete the connection, without the need for additional tools or complicated steps. This not only improves installation efficiency, but also reduces operational difficulty and safety risks. BRIEF DESCRIPTION OF THE DRAWINGS

Certain portions of certain drawings may be exaggerated to illustrate relevant details or structures of the embodiments of the present disclosure.

[0024] See also Figure 1-5 , an embodiment provided by the utility model:

[0025] A water-leakage-proof fire valve comprises a fire valve body 1, one side of the fire valve body 1 is connected to a connecting pipe 2, and one end of the connecting pipe 2 is connected to a clamping ring 911, the inner wall of the clamping ring 911 is fixedly installed with a connecting ring 9, and one end of the connecting ring 9 is connected to a limiting ring 7, an abutting tube 8 is movably installed between the clamping ring 911 and the limiting ring 7, and a limiting plate 5 is fixedly installed on one side of the abutting tube 8, one end of the limiting plate 5 is connected to a water pipe 6, the outer surface of the clamping ring 911 is provided with threads and multiple groups of vertical through grooves 912, and the outer surface of the clamping ring 911 is movably installed with an extrusion tube 3.

[0026] Furthermore, multiple sets of operating rods 4 are fixedly installed on the outer surface of the extrusion tube 3, and one end of the multiple sets of operating rods 4 is arc-shaped, which makes the operator feel better when rotating and easier to apply force, thereby improving the efficiency of installation and disassembly.

[0027] Furthermore, an airbag 913 is installed on the inner wall of the clamping ring 911. The airbag 913 can fill the tiny gap between the abutment tube 8 and the clamping ring 911 when the clamping ring 911 contracts, thereby enhancing the sealing effect, effectively preventing water or liquid leakage, and improving the reliability of the entire fire valve system.

[0028] Furthermore, one end of the abutting tube 8 is in an arc shape, and the outer surface of the abutting tube 8 is wrapped with rubber. The arc shape of one end of the abutting tube 8 makes the contact with the clamping ring 911 and the limit ring 7 more uniform, reduces the stress concentration point, and thus extends the service life. At the same time, the outer surface of the abutting tube 8 is wrapped with rubber, which increases the friction between the clamping ring 911, making the connection more stable, and the rubber material can also provide a certain elasticity, which helps to seal.

[0029] Furthermore, a snap-fit ​​groove is provided on one side of the limiting plate 5, and the snap-fit ​​groove is wrapped with rubber. The snap-fit ​​groove makes the connection between the extrusion tube 3 and the limiting plate 5 more stable and not easy to fall off, and the elasticity of the rubber can also provide a certain sealing effect to prevent water or liquid leakage.

[0030] Furthermore, one end of the extruded tube 3 is conical, so that during the rotation, the bottom of the cone can gradually squeeze the clamping ring 911, thereby achieving tight clamping of the abutting tube 8.

[0031] Furthermore, the connecting ring 9 is made of a magnetic material, so that when the abutting tube 8 is inserted, the connecting ring 9 can immediately adsorb the abutting tube 8, thereby ensuring its stability in the initial position.

[0032] Working principle: When the water pipe is not connected, an open space is formed between the clamping ring 911 and the limiting ring 7 to accommodate one end of the abutting tube 8. The outer surface of the clamping ring 911 is provided with threads and multiple sets of vertical through grooves 912. The extruded tube 3 is rotatably mounted on the outside of the clamping ring 911. First, the extruded tube 3 is rotated to the outside of one end of the clamping ring 911 to provide space for the insertion of the abutting tube 8. Then, one end of the abutting tube 8 is inserted into the space between the clamping ring 911 and the limiting ring 7. When the end of the abutting tube 8 contacts the connecting ring 9, since the connecting ring 9 is made of magnet material, it will immediately adsorb the abutting tube 8 to ensure its stability in the initial position. After completing the initial adsorption, the extruded tube 3 is rotated in the opposite direction. Since one end of the extrusion tube 3 is conical, as it rotates and moves downward, its inner wall will gradually squeeze the outer surface of the clamping ring 911, causing the clamping ring 911 to shrink along the thread direction and tightly clamp the abutting tube 8. During the contraction of the clamping ring 911, the air bag 913 of the vertical through groove 912 inside it will deform when squeezed and fill any tiny gap between the abutting tube 8 and the clamping ring 911, thereby greatly enhancing the sealing effect and enhancing the overall waterproof and leak-proof performance.

[0033] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention. Any reference sign in a claim should not be construed as limiting the claim to which it relates.
