Detailed Description

The present application is described in further detail below with reference to figures 1-3.

The embodiment of the application discloses an electric valve. Referring to fig. 1 and 2, the electric valve is mounted on the water pipe 1 to control the opening and closing of the water pipe 1. The motorised valve includes electronic executor 2 and connecting tube 3, and electronic executor 2 is used for controlling connecting tube 3's intercommunication and closure, and electronic executor 2 is installed directly over connecting tube 3, and the lower extreme of electronic executor 2 stretches into in the connecting tube 3 inner chamber.

The both ends of connecting tube 3 slide respectively and are connected with a connecting sleeve 4, offer on the inner wall of connecting sleeve 4 to be used for with carry out the internal thread that is connected with water pipeline 1, connecting tube 3 links together through connecting sleeve 4 with water pipeline 1.

Under the condition that the water pipeline 1 position is fixed at the motorised valve both ends, when the motorised valve breaks down, the staff can revolve two adapter sleeve 4 on the connecting tube 3 of twisting respectively, make adapter sleeve 4 be close to electronic executive component 2 along the length direction of connecting tube 3, the terminal surface that deviates from electronic executive component 2 and connecting tube 3's terminal surface parallel and level up to adapter sleeve 4, adapter sleeve 4 no longer takes place the contact with water pipeline 1 this moment, the staff can be at the electronic executive component 2 of not rotating, the motorised valve is pulled down under connecting tube 3 and the condition with water pipeline 1, thereby it is more convenient when dismantling the motorised valve to make the staff.

Referring to fig. 2 and 3, an annular shoulder 31 is integrally formed on the outer side walls of both ends of the connecting pipe 3, and a snap ring 41 for engaging with the shoulder 31 is integrally formed on the inner side surface of the end portion of the connecting sleeve 4 facing the electric actuator.

Referring to fig. 2 and 3, the shoulder 31 can limit the moving range of the connection sleeve 4 by the snap ring 41 during the sliding of the connection sleeve 4 on the connection pipe 3, thereby improving the integrity between the connection sleeve 4 and the connection pipe 3 and reducing the separation of the connection sleeve 4 from the connection pipe 3.

The connecting sleeve 4 is provided with a sealing ring 42 at a position close to the electric actuator 2, and the connecting pipeline 3 is hermetically connected with the connecting sleeve 4 through the sealing ring 42, so that the condition that water flow leaks from the connecting sleeve 4 to the connecting pipeline 3 is reduced.

In particular, the sealing ring 42 may be fixed to the inner wall of the connection sleeve 4 at a position close to the electric actuator 2, and the sealing ring 42 may also be fixed coaxially to the side of the snap ring 41 facing the shoulder 31. In order to reduce the wear to which the sealing ring 42 is subjected during the sliding movement of the connection sleeve 4, the sealing ring 42 in the exemplary embodiment of the present application is coaxially adhesively fastened to the side of the retaining ring 41 facing the shoulder 31.

Referring to fig. 2 and 3, the inner side surface of the snap ring 41 is an arc-shaped surface, and the arc-shaped surface smoothly connects the surface of the snap ring 41 facing the electric actuator 2 and the surface of the snap ring 41 facing away from the electric actuator 2. The surface contact mode between the clamping ring 41 and the connecting pipeline 3 is converted into line contact, so that the contact area between the clamping ring 41 and the connecting pipeline 3 is reduced, and the clamping condition between the clamping ring 41 and the connecting pipeline 3 when the connecting sleeve 4 slides relatively on the connecting pipeline 3 is reduced.

In order to facilitate the operator to screw the connection sleeve 4, the connection sleeve 4 is provided with a screw part 43, and the outer contour line of the cross section of the screw part 43 is polygonal. In the present embodiment, the outer contour line of the screw portion 43 is a regular hexagon coaxial with the joint sleeve 4.

The length of the connecting pipeline 3 is equal to the distance between the ends of the two water pipelines 1 which need to be communicated through the connecting pipeline 3. When the operator installs the electric valve between the water using pipes 1, the gap between the connecting pipe 3 and the water using pipe 1 is reduced as much as possible, thereby improving the stability of connection between the connecting pipe 3 and the water using pipe 1.

Referring to fig. 2 and 3, an annular sealing groove with a semicircular cross section is coaxially formed in the end face of the connecting pipeline 3 away from the electric actuator 2, a sealing ring 32 is embedded in the sealing groove, and after the electric valve is installed and is communicated with the water pipeline 1, the water pipeline 1 and the connecting pipeline 3 are in sealing connection through the sealing ring 32.

Along with the tightening of adapter sleeve 4 and water pipe 1, connecting tube 3 receives the pulling force with water pipe 1 and is close to each other to increased connecting tube 3 gradually and used the water pipe 1 to the extrusion force of sealing washer 32, and then improved connecting tube 3 and used the sealed effect between water pipe 1, reduced rivers from connecting tube 3 and the condition of overflowing between water pipe 1.

The implementation principle of an electrically operated valve in the embodiment of the application is as follows:

when the operator installs the electric valve, the positions of the hard water pipes 1 at the two ends are already fixed. The staff puts connecting tube 3 between two sections with water pipeline 1 with the water pipeline 1 is coaxial earlier, extrudees sealing washer 32 with the terminal surface that water pipeline 1 and connecting tube 3 oriented each other for sealing washer 32 seals the position of being connected with water pipeline 1 and connecting tube 3.

The union sleeve 4 is then screwed so that the union sleeve 4 is screwed with the end of the water pipe 1 until the shoulder 31 is tightly abutted against the seal ring 42 on the snap ring 41, thereby mounting the electric valve on the water pipe 1.

When the electric valve breaks down, a worker can smoothly detach the electric valve from the water using pipeline 1 only by screwing the connecting sleeve 4, so that the difficulty of the electric valve in mounting or detaching is reduced, and the electric valve is more convenient to mount and replace.

The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
