Abstract

The invention relates to valves, in particular to a valve capable of changing flow directions. A reversing valve is composed of a valve body, a valve cover, a valve core and a locating pin. The valve body is provided with three channels including one inlet channel and two outlet channels. The axes of an inlet and outlets of the channels form a 45-degree angle, the valve core is provided with a channel, a channel opening of the valve core is in butt joint with channel openings of the valve body, and the valve core and the valve body can form two channels. The two channels are used as the channels of the reversing valve for a medium to pass through, and the valve core rotates in the valve body to switch the channels to change the flow directions of the medium. In order to connect the valve core and a port of the valve body correctly, the locating pin is adopted to limit rotation of the valve core, the valve core can only rotate through 45 degrees, after rotation of a 45-degree angle, a connecting port between the valve core and the valve body is changed through the channel opening of the valve core, another channel of the reversing valve is formed, and a working path of the working medium of the reversing valve is changed. A working system loop is changed into another working system loop.

Description

Selector valve

Technical field: the present invention relates to valve, particularly change the valve flowed to.

Background technique: the technology of solar energy is in continuous development, the sun heat energy utilization work system loop works, the work system loop is to adopt multiloop work system, a kind of working forms, convert another kind of working forms to, need selector valve a kind of work system loop of form, change the work system loop of another kind of form into.

Summary of the invention: the work system loop of solar energy, the heat exchange work of a kind of form of WKG working, need the work system loop to do the heat exchange work of another kind of form, utilize selector valve that the form in work system circuit cycle loop is changed, become the heat exchange work of another kind of form, namely the circuit type in work system loop is changed, working forms is changed.

The technical solution scheme: selector valve is by valve body 1, valve gap 2, valve core 3, locating stud 4 forms, valve body 1 has three passage (Fig. 4, Fig. 5), an inlet passage and two outlet passages, the axis import of passage becomes miter angle with the export mixes central axis, valve core 3 has a passage, the passway of valve core 3 can be docked with the passway of valve body 1, with valve body 1, can form two passages (Fig. 4, Fig. 5).Can be by the passage of medium for selector valve, valve core 3 is in the interior rotation of valve body 1, the meeting ALT-CH alternate channel changes the flow direction (Fig. 2, Fig. 3) of medium, in order to make valve core 3 and the interface of valve body 1, can accurately join, adopt locating stud 4 restriction valve cores 3 to rotate, can only rotate 45 degree, after rotating 45 degree, the passway of valve core 3 has changed the connection mouth with valve body 1, become another passage of selector valve, make the selector valve working medium change operating path.Make the work system loop change into another work system loop (Fig. 2, Fig. 3).

Embodiment: be processed into three passages that axle center becomes 45 degree on valve body 1, valve core 3 is processed into a passage, with one 45 spacing triangular groove (Fig. 4 of degree, Fig. 5), valve core 3 is arranged in valve body 1, locating stud 4 is arranged in valve core 3 triangular grooves, the bottom of valve body 1, restriction valve core 3 can only be at the interior rotation 45 degree (Fig. 4 of valve body 1, Fig. 5), the stop position of on the left side, the passway of valve core 3 can accurately be docked with the passway of valve body 1, form a passage, valve core 3 rotates the position of the limit stop of keeping right, valve core 3 is changed with the passway of valve body 1, from passage (Fig. 4 of new composition, Fig. 5).

Beneficial effect: structure subtracts list, and connection mouth docking accurately, is applied in the work system loop and can forms two work system loops and do different work.

The accompanying drawing explanation:

Fig. 1 is the selector valve plan view.

Fig. 2 is selector valve work system loop works figure in the work system loop.

Fig. 3 is that selector valve is converted to another work system loop works figure to the work system loop in the work system loop.

Fig. 4 is the A face figure of Fig. 1.

Fig. 5 is that the valve of Fig. 4 rotates 45 degree figure.

In figure, 1 valve body.2 valve gaps.3 valve cores.4 locating studs.
