Description

Technical Field

[0001] The utility model belongs to the technical field of thermal management integration, and in particular relates to a valve shell structure of an integrated water valve assembly. Background Art

[0002] The valve housing of an integrated water valve assembly is typically made of high-quality materials to ensure sufficient strength and corrosion resistance. Structurally, the valve housing may contain multiple valve cores, sealing structures, and fluid channels, all of which are integrated through precision machining and assembly processes. An integrated water valve consists of a valve housing, valve cover, and valve core. The valve housing and valve cover must form a sealed, leak-proof whole.

[0003] The previous design was to install a sealing ring on the valve cover and fix it to the valve housing with 6 screws. The sealing ring of the existing water valve assembly scheme is easily crushed during the assembly process, causing leakage. At the same time, the torque of the screws and the poor roundness of the sealing between the valve housing and the valve cover plate can also cause leakage. In terms of the installation process, one station is used to install the sealing ring and another station is used to lock the 6 screws, which is relatively cumbersome. Therefore, we proposed another integrated water valve assembly valve housing structure. Utility Model Content

[0004] The purpose of the utility model is to provide a valve housing structure of an integrated water valve assembly. By arranging a circular ring, the valve housing and the valve cover plate are laser welded, the sealing ring and screws are eliminated, and the direct material cost is reduced. The design of the U-shaped groove increases the space at the root of the groove, so that the welding heat source can penetrate into the root of the joint, thereby ensuring the weld penetration of the weld root, thereby improving the strength and sealing of the weld, and solving the problem of the existing water valve assembly scheme that the sealing ring is easily crushed during the assembly process, resulting in leakage. At the same time, the size of the screw torque and the poor roundness of the sealing part of the valve housing and the valve cover plate will also cause leakage. In terms of the installation process, one station is used to install the sealing ring and one station is used to lock 6 screws, which is a relatively cumbersome problem.

[0005] In order to solve the above technical problems, the present invention is achieved through the following technical solutions:

[0006] The utility model is a valve housing structure of an integrated water valve assembly, comprising a valve housing, the outer surface of which is provided with a mesh frame for wrapping, the outer surface of which is provided with two mounting bolts, a valve cover plate provided on the top of the valve housing, a valve core fixedly connected to the inner wall of the valve housing, the top of the valve core being slidably connected to the inner wall of the valve cover plate, and the mesh frame on the surface of the valve housing being able to enhance the strength of the valve housing and prevent excessive internal pressure;

[0007] The top of the valve housing is fixedly connected with a circular ring 1, and the side of the circular ring 1 close to the valve cover plate is an arc-shaped concave surface. The inner wall of the circular ring 1 is inserted with a circular ring 2, and the side of the circular ring 2 away from the valve housing is fixedly connected to the bottom of the valve cover plate. The side of the circular ring 2 close to the circular ring 1 is an arc-shaped concave surface. A U-shaped groove is formed at the junction of the circular ring 2 and the circular ring 1. The design of the U-shaped groove increases the space at the root of the groove, so that the welding heat source can penetrate into the root of the joint, thereby ensuring the weld penetration of the weld root, thereby improving the strength and sealing of the weld.

[0008] Furthermore, four calibration components are provided at the bottom of the valve cover plate. The calibration components include limit rods fixedly connected to the bottom of the valve cover plate. The limit rods are used to calibrate and align the valve cover plate and the valve housing.

[0009] Furthermore, a groove is provided inside the limiting rod, and a limiting block is provided inside the groove, and the limiting block moves inside the groove.

[0010] Furthermore, a fixed block is provided on the side of the limiting block away from the limiting rod, and the side of the limiting block close to the fixed block is arc-shaped. The arc-shaped surface of the limiting block facilitates the movement of the limiting block when in contact with the fixed block and will not get stuck.

[0011] Furthermore, the outer surface of the fixed block is fixedly connected to the inner wall of the valve housing, and the inner wall of the fixed block is slidably connected to the outer surface of the limiting rod. Since the limiting rod is fixed to the bottom of the fixed block through the limiting block, the simple fixed connection can reduce vibration and shaking during welding, making the welding process more stable. The elastic force generated by the spring pushes the limiting block away from the inside of the groove, and the limiting block is fixed to the bottom of the fixed block.

[0012] Furthermore, a spring is provided inside the groove, and one end of the spring close to the fixing block is fixedly connected to the outer surface of the limiting block.

[0013] The utility model has the following beneficial effects:

[0014] 1. The utility model sets a circular ring 1, specifically a circular ring 2 set at the bottom of the cover plate, which fits the inner wall of the circular ring 1 set at the top of the valve housing. The sides of the circular ring 1 and the circular ring 2 that are close to each other are both arc-shaped concave surfaces. After the circular ring 1 and the circular ring 2 come into contact with each other, the contacting surfaces form a U-shaped groove. The valve housing and the valve cover plate are laser welded, and the sealing ring and screws are eliminated, and the direct material cost is reduced. The design of the U-shaped groove increases the space at the root of the groove, so that the welding heat source can penetrate into the root of the joint, thereby ensuring the weld penetration of the weld root, thereby improving the strength and sealing of the weld.

[0015] 2. The utility model sets a calibration component. Specifically, when the limiting block is pushed by the limiting rod to move to the bottom of the fixed block, the elastic force generated by the spring pushes the limiting block away from the inside of the groove, and the limiting block is fixed at the bottom of the fixed block. At this time, the circular ring 2 and the circular ring 1 fit each other. Before welding the valve housing and the mounting bolts, a positioning device is set to ensure fast and accurate alignment between the two. Then the staff welds the contact points of the circular ring 1 and the circular ring 2. Since the limiting rod is fixed to the bottom of the fixed block through the limiting block, the simple fixed connection can reduce vibration and shaking during welding, making the welding process more stable, thereby improving the quality of the welded joint.

The inner wall of the ring 1 201 is plugged with a ring 202. The side of the ring 202 away from the valve housing 1 is fixedly connected to the bottom of the valve cover plate 102.

Before welding the valve housing 1 and the mounting bolt 101, a positioning device is set to ensure quick and accurate alignment between the two without consuming extra time. Then the staff welds the contact points of the ring 1 201 and the ring 2 202.
