Obviously, the described embodiments are only some of the embodiments of the present application, but not all of the embodiments. The following description of at least one exemplary embodiment is merely exemplary in nature and does not limit the present application and its application or use in any way. Based on the embodiments in the present application, all other embodiments that a person skilled in the art can obtain without creative labor are within the scope of protection of the present application.

[0018] As shown in Figures 1 to 5, the motor-operated valve of the embodiment of the present application includes a valve seat 10, a valve body 20, a coil portion 30 and a connection portion 40, the valve seat 10 includes an end face 11 and an engagement groove 12, a portion of the valve body 20 is inserted into the valve seat 10 and another portion protrudes from the end face 11, the coil portion 30 is fitted onto the valve body 20, the coil portion 30 and the engagement groove 12 are located on both sides of the end face 11, the connection portion 40 includes a connection member 41, and a support member 42 and an engagement member 43 installed on the connection member 41, the connection member 41 is fixedly connected to the coil portion 30, the support member 42 abuts against the end face 11, and the engagement member 43 is engaged with the engagement groove 12.

[0019] In this embodiment, a portion of the valve body 20 is inserted into the valve seat 10, and another portion protrudes from the end face 11, which facilitates the corresponding installation between the coil portion 30, the connection portion 40, and the valve seat 10. The coil portion 30 is located above the end face 11, and the locking groove 12 is located below the side of the end face 11, which facilitates the connection between the connection portion 40 connected to the coil portion 30 and the valve seat 10. The connecting member 41 is fixedly connected to the coil portion 30, the support member 42 abuts against the end face 11, and the locking member 43 is locked in the locking groove 12, thereby achieving a fixed connection between the connection portion 40 and the valve seat 10.

[0020] By using this solution, when attaching the coil portion 30, it is sufficient to lock the locking member 43 of the connection portion 40 with the locking groove 12 in the valve seat 10, and after locking is completed, the support member 42 abuts against the end face 11 of the valve seat 10, thereby restricting the position of the coil portion 30 in two axial directions, thereby achieving a reliable connection between the coil portion 30 and the valve seat 10. By using this solution, the connection can be achieved at the same time as inserting the coil portion 30 into the valve body 20, and there is no need to screw in a screw, improving assembly efficiency and preventing the connection from loosening even in a vibration environment.

[0021] Furthermore, the support member 42 has an elastic structure. The support member 42 uses an elastic structure, which can better perform the functions of supporting and restricting the position when the coil part 30 and the valve seat 10 are connected by the connection part 40, and can better perform the fastening function after the coil part 30 and the valve seat 10 are fixed. Since the support member 42 can be elastically deformed during assembly and removal, it is possible to easily lock the locking member 43 into the locking groove 12 or remove it from the locking groove 12.

[0022] Furthermore, the support member 42 includes an arc-shaped plate 44 and a position limiting plate 45 connected to each other, the arc-shaped plate 44 is connected to the connecting member 41, the position limiting plate 45 abuts against the end face 11, and the position limiting plate 45 is spaced from the connecting member 41 and is installed at an incline with respect to the end face 11. The support member 42 uses the arc-shaped plate 44 to cushion the radial force generated when the support member 42 abuts against the end face 11, and can protect the connection between the support member 42 and the connecting member 41. In addition, by using a method in which the position limiting plate 45 is installed at an incline with respect to the end face 11, the position limiting plate 45 becomes more elastically deformable, and when the position limiting plate 45 of the support member 42 abuts against the end face 11, it can perform a good position limiting function.

[0023] Preferably, there are multiple support members 42, and the multiple support members 42 are installed surrounding the valve body 20. The multiple support members 42 work together to reduce the pressure that each support member 42 receives when it comes into contact, providing a protective effect for the entire connection portion 40, and improving the fastening effect after the support members 42 and the valve seat 10 are engaged with each other.

[0024] 3 to 5, the valve seat 10 includes a main body 13 and a position limiting portion 14, the end face 11 is located on the main body 13, the main body 13 has a step structure, the position limiting portion 14 is located on a side surface 15 of the step structure, and the region between the position limiting portion 14 and a bottom surface 16 of the step structure forms an engagement groove 12. With the above structure, the engagement groove 12 can be formed in the valve seat 10 to engage with the connecting portion 40.

[0025] In this embodiment, the body 13 of the valve seat 10 has a stepped structure, the position limiting portion 14 is located in the stepped structure, and a locking groove 12 is formed between the side surface 15 of the stepped structure and the bottom surface 16 of the stepped structure. This design facilitates the processing of the locking groove 12 and the arrangement of the position limiting portion 14, and the locking groove can be formed by the stepped structure attached to the body 13, making the structure simple and convenient to process.

[0026] Specifically, the position limiting portion 14 includes a position limiting groove 17 extending along the axial direction of the valve body 20, and the locking member 43 includes a connecting plate 46 and a locking hook 47, both ends of the connecting plate 46 are connected to the connecting member 41 and the locking hook 47, respectively, the locking hook 47 is locked in the locking groove 12, and the connecting plate 46 is positionally limited and engaged with the position limiting groove 17.

[0027] The locking hook 47 is locked in the locking groove 12, and the connecting plate 46 is engaged with the position limiting groove 17 while being positionally limited; this design facilitates the locking of the locking hook 47 with the locking groove 12, and also makes it possible to limit the position of the connecting plate 46 in the circumferential direction by the position limiting engagement between the connecting plate 46 and the position limiting groove 17, thereby limiting the position of the coil portion 30 in the circumferential direction. Both ends of the connecting plate 46 are connected to the connecting member 41 and the locking hook 47, respectively, and after the locking is completed, the support member 42 abuts against the end face 11 of the valve seat 10, thereby making it possible to limit the position of the coil portion 30 in two axial directions, thereby realizing a reliable connection between the coil portion 30 and the valve seat 10.

[0028] 3 and 4, the connection part 40 further includes a pull member 48 connected to a middle part of the locking member 43. During operation, an operator can pull the pull member 48 to move the locking member 43. The pull member 48 is installed in the middle part of the locking member 43 and can have a certain adjustment function during the locking process to prevent the locking or disengagement of the locking hook 47 at the connection part 40 from becoming difficult.

[0029] figure 4 As shown in FIG. 1, the connection member 41 has an annular structure, which allows the valve body 20 to escape, so that the valve body 20 can penetrate the connection member 41. The connection member 41 has a plurality of through holes 49 distributed therein, and the coil part 30 includes a plurality of protruding posts 31 which are engaged with the plurality of through holes 49 in a one-to-one position restriction manner. This engagement manner can better restrict the positions of the coil part 30 and the connection part 40, and the plurality of protruding posts 31 are engaged with the through holes 49 in a one-to-one position restriction manner, so that the stability of the structure can be better guaranteed. The protruding posts 31 and the through holes 49 may be fixedly connected by a manner such as riveting or welding.

[0030] Specifically, the connection part 40 is an integral structure made of a metal material. Since the connection part 40 is made of a metal material and has high mechanical strength, it can increase the connection strength between the valve seat 10 and the coil part 30. The connection part 40 can be a sheet metal or a pressed part, which makes it easy to process and reduces costs.

[0031] Specifically, the valve body 20 is screwed into the valve seat 10. The screwing makes it easy to install, easy to remove, and easy to operate.

[0032] 4, a recess structure is provided at the connection point between the connecting member 41 and the locking member 43. This design can avoid the problem that the locking member 43 is too rigid and difficult to remove, and can improve its elasticity.
