The technical scheme adopted by the utility model for solving the technical problems is as follows: a conversion valve comprises a valve body, a valve core and an end cover used for locking the valve core in the valve body, wherein the valve core comprises a conversion part and rotating parts connected to the two ends of the conversion part, a notch is formed in the conversion part, a conversion cavity hermetically matched with the conversion part is formed in the valve body, the conversion cavity is cylindrical, so that the conversion part can rotate in the conversion cavity, and a first opening, a second opening and a third opening which are communicated with the conversion cavity are formed in the valve core; by rotating the valve body, the first opening can be made to communicate with the second opening only through the slit, or the second opening can be made to communicate with the third opening only through the slit.

A diverter valve as described above, wherein the centre line of said first port is co-linear with the centre line of the third port.

In the above switching valve, the center line of the second port is perpendicular to the center line of the first port.

In a switching valve as described above, the cutout has a "U" shape in cross section.

In a switching valve as described above, the cut-out is in smooth transition with the first, second and third openings.

In the switching valve, the rotating part is connected with a wrench arm for driving the valve plug to rotate.

According to the change-over valve, one end of the wrench arm is provided with the mortise, and the rotating part is provided with the tenon embedded into the mortise.

The utility model has the beneficial effects that:

1. the switching valve has the advantages of simple structure, low cost, easy processing and manufacturing and simple maintenance.

The utility model will be further described with reference to the accompanying drawings and specific embodiments.

Detailed Description

Embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

As shown in fig. 1 to 7, the switching valve of the present embodiment includes a valve body 1, a valve core 2, and an end cover 3 for locking the valve core 2 in the valve body 1, where the valve core 2 includes a switching portion 21 and rotating portions 22 connected to two ends of the switching portion 21, a notch 211 is formed on the switching portion 21, a switching chamber 100 hermetically fitted with the switching portion 21 is formed on the valve body 1, the switching chamber 100 is cylindrical, so that the switching portion 21 can rotate in the switching chamber 100, and a first opening 101, a second opening 102, and a third opening 103 communicated with the switching chamber 100 are formed on the valve core 2; by rotating the valve body 2, the first port 101 can be made to communicate with the second port 102 only through the notch 211, or the second port 102 can be made to communicate with the third port 103 only through the notch 211. The switching valve has the advantages of simple structure, low cost, easy processing and manufacturing and simple maintenance.

In this embodiment, the first opening 101 and the third opening 103 are oppositely arranged, and the central line of the first opening 101 is collinear with the central line of the third opening 103; the center line of the second opening 102 is perpendicular to the center line of the first opening 101. The design is convenient for processing.

In this embodiment, the cross-section of the notch 211 is "U" shaped, which facilitates the processing of the notch on the valve core.

In this embodiment, the cut 211 and the first, second, and

third openings

101, 102, and 103 are in smooth transition, so that adhesion of the material in the conversion cavity can be reduced.
