Description

Technical Field

[0001] This utility model belongs to the technical field of valve body accessories, and relates to a valve sleeve that is easy to assemble. Background Technology

[0002] The valve core and valve sleeve are important components of a solenoid valve. During the production and assembly process of a solenoid valve, it is necessary to first accurately install the valve core into the valve sleeve, and then connect and assemble the valve core and valve sleeve with other structures of the solenoid valve. In the existing technology, the valve core is pushed into the valve sleeve by force without a guide structure, which makes the valve sleeve easy to wear during assembly and results in poor installation effect, which needs to be improved. Summary of the Invention

[0003] The purpose of this invention is to provide a valve sleeve that is easy to assemble, so as to solve the problems mentioned in the background art.

[0004] The objective of this utility model can be achieved through the following technical solutions:

[0005] A valve sleeve that is easy to assemble includes a metal outer sleeve, a guide seat one, and a guide seat two. The two ends of the metal outer sleeve are respectively connected to the guide seat one and the guide seat two. The guide seat one and the guide seat two are each provided with an inner guide frame. An insertion port is provided at the center of the inner guide frame. Two symmetrically arranged limiting grooves are opened on the inner wall of the insertion port. A ceramic inner sleeve is installed inside the metal outer sleeve.

[0006] In the aforementioned valve sleeve designed for easy assembly, limit support arms are provided at both ends of the ceramic inner sleeve, and a metal sleeve plate is bonded to the outer side of the limit support arm. Both the limit support arm and the metal sleeve plate are placed inside the limit groove.

[0007] In the aforementioned valve sleeve designed for easy assembly, the outer wall surfaces of guide seat one and guide seat two are provided with fixing holes, and locking screws are installed inside the fixing holes.

[0008] In the aforementioned valve sleeve designed for easy assembly, a positioning hole is provided at the front end of the metal sleeve plate, and the front end of the locking screw passes through the fixing hole and is threaded into the interior of the positioning hole.

[0009] In the aforementioned valve sleeve designed for easy assembly, the outer wall of the metal sleeve is provided with multiple reinforcing rings, and the side of each reinforcing ring is provided with a flow guide.

[0010] Compared with the prior art, the advantages of this utility model's easy-to-assemble valve sleeve are:

[0011] This application incorporates a ceramic inner sleeve within a metal outer casing. Limiting support arms at both ends of the ceramic inner sleeve are engaged within limiting grooves, thus supporting the ceramic inner sleeve. This ensures the entire valve sleeve possesses the sealing and lubrication properties of ceramic, reducing wear. Simultaneously, the metal outer casing provides external protection, extending the valve sleeve's service life. Guide seats one and two are located at both ends of the metal outer casing, each containing an inner guide frame. When installing the valve core inside the valve sleeve, the inner guide frame guides the valve core into the ceramic inner sleeve within the metal outer casing, completing the installation process. Assembly is simple and efficient. Attached Figure Description

[0016] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0017] A valve sleeve that is easy to assemble includes a metal outer sleeve 1, a guide seat 1 2, and a guide seat 2 3. The two ends of the metal outer sleeve 1 are respectively connected to the guide seat 1 2 and the guide seat 2 3. The guide seat 1 2 and the guide seat 2 3 are both provided with a guide inner frame 8. The guide inner frame 8 is provided with an insertion port 9 at its center. The inner wall of the insertion port 9 is provided with two symmetrically arranged limiting grooves 10. A ceramic inner sleeve 6 is installed inside the metal outer sleeve 1.

[0018] like Figure 1 , Figure 2 , Figure 3 As shown, this utility model provides a valve sleeve that is easy to assemble. Specifically, the ceramic inner sleeve 6 has limit support arms 12 at both ends, and a metal sleeve plate 13 is bonded to the outside of the limit support arm 12. Both the limit support arm 12 and the metal sleeve plate 13 are placed inside the limit groove 10.

[0019] like Figure 1, Figure 2 , Figure 3 As shown, this utility model provides a valve sleeve that is easy to assemble. Specifically, the outer wall surface of the guide seat 1 2 and the outer wall surface of the guide seat 2 3 are provided with fixing holes 7, and locking screws 11 are provided inside the fixing holes 7.

[0020] like Figure 1 , Figure 2 , Figure 3 As shown, this utility model provides a valve sleeve that is easy to assemble. Specifically, the front end of the metal sleeve plate 13 is provided with a positioning hole 14, and the front end of the locking screw 11 passes through the fixing hole 7 and is threaded into the interior of the positioning hole 14.

[0021] like Figure 1 , Figure 2 , Figure 3 As shown, this utility model provides a valve sleeve that is easy to assemble. Specifically, the outer wall of the metal jacket 1 is provided with multiple reinforcing rings 4, and the side of the reinforcing rings 4 is provided with a flow guide port 5. The reinforcing rings 4 strengthen the overall strength of the metal jacket 1.

[0022] This utility model discloses a valve sleeve that is easy to assemble. A ceramic inner sleeve 6 is set inside the metal outer sleeve 1. The limiting support arms 12 at both ends of the ceramic inner sleeve 6 are locked inside the limiting groove 10 and locked by locking screws 11, thereby supporting the ceramic inner sleeve 6. In this way, the entire valve sleeve can be guaranteed to have the sealing and lubrication properties of ceramic, reducing wear. At the same time, the outside of the valve sleeve is protected by the metal outer sleeve 1, thus extending the service life of the valve sleeve. This application provides guide seats 1 2 and guide seats 2 3 at both ends of the metal outer sleeve 1. The guide inner frame 8 is set inside the guide seats 1 2 and guide seats 2 3. When installing the valve core inside the valve sleeve, the guide inner frame 8 can guide the valve core into the ceramic inner sleeve 6 inside the metal outer sleeve 1, thereby completing the installation. The entire valve core assembly is simple and efficient.
