Description

Technical Field

[0001] This utility model relates to the field of valve technology, and in particular to a press-fit valve connector assembly. Background Technology

[0002] A press-fit valve fitting assembly is a component used to connect valves and pipes. By using a special tool to press, the valve fitting is tightly connected to the steel pipe, thereby ensuring the stability and sealing of the connection. Therefore, a press-fit valve fitting assembly is used.

[0003] To address this, patent CN217328544U discloses a press-fit valve connector assembly, comprising a valve and a pipe. The valve has press-fit valve connector assemblies at both ends, which are connected to the valve ends. The pipe is inserted into the inner cavity of the press-fit valve connector assembly, and a special tool is used to press and secure the press-fit valve connector assembly to the pipe. The press-fit valve connector assembly consists of a connector body, a first sealing ring, a second sealing ring, a toothed ring, and a washer. The advantages of this invention are that it connects a traditional valve and a press-fit valve connector assembly, making on-site construction convenient, safe, and efficient, avoiding the potential leakage at the joint caused by improper wrapping of raw rubber tape during threaded connections. The valve and pipe are standard parts, readily available for purchase in various regions. The press-fit valve connector assembly is manufactured in a factory assembly line, increasing work efficiency by more than 40% and reducing production costs by more than 35% compared to existing technologies. It has broad market prospects and significant economic benefits.

[0004] While the aforementioned press-fit valve fitting assembly avoids the risk of leakage at the joint caused by improper wrapping of raw rubber tape during threaded connections, it is inconvenient to fix it during use, and it is also inconvenient to prevent loosening during fixing, thus making it difficult to ensure the stability of the connection. Utility Model Content

[0005] The purpose of this invention is to provide a press-fit valve connector assembly to solve the problem of inconvenience in fixing existing press-fit valve connector assemblies.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a press-fit valve joint assembly, including a valve seat and a steel pipe;

[0007] A valve cover is installed on the top of the valve seat, and both ends of the valve seat are threadedly connected to a fixing structure.

[0008] The outer side of the fixed structure away from the valve seat is threaded with a connecting structure.

[0009] A steel pipe is installed at one end of each of the internal connection structures.

[0010] When using this device, the fixed structure facilitates its anti-loosening function, thereby improving the stability of the press-fit valve joint assembly during use; the connection structure facilitates its sealing function, thereby improving the applicability of the press-fit valve joint assembly during use.

[0011] Preferably, the fixing structure includes double external threads, a first sealing ring, a rubber strip, a second sealing ring, a placement groove, and a snap-fit ​​groove. The double external threads are threaded to both ends inside the valve seat. Placement grooves are provided at both ends of the double external threads. A second sealing ring is provided inside each placement groove. A first sealing ring is fitted on the outer side of both ends of the double external threads. A rubber strip is fixed to the inner side of each first sealing ring. A snap-fit ​​groove is provided inside the double external threads on one side of the rubber strip.

[0012] Preferably, the second sealing ring and the double external threads form an engaging structure through a placement groove, with one end of the double external threads abutting against the inner wall of the valve seat. Under the action of the second sealing ring, an excellent sealing effect is achieved, preventing liquid or gas leakage.

[0013] Preferably, the rubber strip and the double external wires form an engaging structure through a snap-fit ​​groove, and one side of the first sealing ring at one end of the double external wires abuts against the outer wall of the valve seat. Under the action of the first sealing ring, the contact area between the double external wires and the valve seat and the press-fit fitting is increased, preventing the double external wires from loosening.

[0014] Preferably, the connection structure includes a crimping fitting, a convex ring, a limiting groove, and a third sealing ring. The crimping fitting is threaded to the outside of one end of the double external thread. A convex ring is fixed to the outside of the crimping fitting. A limiting groove is formed inside the convex ring. A third sealing ring is provided inside each limiting groove.

[0015] Preferably, the crimping fitting and the steel pipe form a sliding structure. One end of the crimping fitting abuts against one side of the first sealing ring, and the inner end of the crimping fitting abuts against one side of the placement groove. The third sealing ring is moved into the limiting groove. Because the third sealing ring has a cavity inside, it deforms under the action of the cavity, increasing the contact area between the third sealing ring and the steel pipe.

[0016] Preferably, the third sealing ring has a cavity inside, and its inner side abuts against the outer wall of the steel pipe. The third sealing ring provides a seal, increases the friction between the steel pipe and the compression fitting, and ensures a secure connection.

[0017] The advantages of the press-fit valve connector assembly provided by this utility model are as follows:

[0018] With a fixed structure, the second sealing ring provides an excellent sealing effect, preventing liquid or gas leakage. The first sealing ring increases the contact area between the double male thread and the valve seat and the press-fit fitting, preventing loosening between the double male thread and the valve seat and the press-fit fitting. This device is designed to prevent loosening and improves the stability of the press-fit valve joint assembly during use.

[0019] By incorporating a connecting structure, the third sealing ring is moved into the limiting groove. The cavity within the third sealing ring causes it to deform, increasing the contact area between the sealing ring and the steel pipe. This seals the pipe and increases the friction between the steel pipe and the press-fit fitting, ensuring a secure connection. This design facilitates sealing and improves the applicability of the press-fit valve connector assembly. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figures 1-5 This utility model provides a press-fit valve connector assembly, including a valve seat 1 and a steel pipe 4. A valve cover 5 is installed on the top of the valve seat 1. Both ends of the valve seat 1 are threadedly connected to a fixing structure 2. The fixing structure 2 includes a double external thread 201, a first sealing ring 202, a rubber strip 203, a second sealing ring 204, a placement groove 205, and a snap-fit ​​groove 206. The double external thread 201 is threaded to both ends of the valve seat 1. Placement grooves 205 are opened at both ends of the double external thread 201. The second sealing ring 204 is provided inside each placement groove 205. Both ends of 01 are fitted with a first sealing ring 202 on the outer side. A rubber strip 203 is fixed to the inner side of the first sealing ring 202. A snap-fit ​​groove 206 is opened inside the double external thread 201 on one side of the rubber strip 203. The second sealing ring 204 and the double external thread 201 form a snap-fit ​​structure through the placement groove 205. One side of the placement groove 205 at one end of the double external thread 201 abuts against the inner wall of the valve seat 1. The rubber strip 203 and the double external thread 201 form a snap-fit ​​structure through the snap-fit ​​groove 206. One side of the first sealing ring 202 at one end of the double external thread 201 abuts against the outer wall of the valve seat 1.

[0028] Reference Figure 4 and Figure 5 As shown, the second sealing ring 204 is moved into the placement groove 205, and the first sealing ring 202 is moved. The first sealing ring 202 drives the rubber strip 203 to move into the snap-fit ​​groove 206. The double external thread 201 is threadedly connected to the valve seat 1 and the crimp fitting 301, thereby fixing the double external thread 201 to the valve seat 1 and the crimp fitting 301. Under the action of the second sealing ring 204, an excellent sealing effect is achieved to prevent liquid or gas leakage. Under the action of the first sealing ring 202, the contact area between the double external thread 201 and the valve seat 1 and the crimp fitting 301 can be increased, which can prevent the double external thread 201 from loosening with the valve seat 1 and the crimp fitting 301.

[0029] The outer side of the fixed structure 2 away from the valve seat 1 is threadedly connected to the connecting structure 3. The connecting structure 3 includes a clamping fitting 301, a convex ring 302, a limiting groove 303, and a third sealing ring 304. The clamping fitting 301 is threadedly connected to the outer side of one end of the double external thread 201. The convex ring 302 is fixed on the outer side of the clamping fitting 301. A limiting groove 303 is opened inside the convex ring 302. A third sealing ring 304 is provided inside the limiting groove 303. The clamping fitting 301 and the steel pipe 4 form a sliding structure. One end of the clamping fitting 301 abuts against one side of the first sealing ring 202. One end inside the clamping fitting 301 abuts against one side of the placement groove 205. A cavity is provided inside the third sealing ring 304. The inner side of the third sealing ring 304 abuts against the outer wall of the steel pipe 4. A steel pipe 4 is provided inside the connecting structure 3.

[0030] Reference Figure 2 and Figure 3 As shown, the third sealing ring 304 is moved into the interior of the limiting groove 303. Since the interior of the third sealing ring 304 has a cavity, one end of the steel pipe 4 is inserted into the interior of the crimp fitting 301. Under the action of the cavity, the third sealing ring 304 deforms, increasing the contact area between the third sealing ring 304 and the steel pipe 4. The crimp fitting 301 and the steel pipe 4 are pressed together by the crimping clamp. Under the action of the third sealing ring 304, a sealing effect is achieved. At the same time, the friction between the steel pipe 4 and the crimp fitting 301 is increased, which also ensures the firmness of the connection.
