Description

a three-way valve

technical field

The utility model belongs to the technical field of fluid control valves, in particular to a special three-way valve for an air-conditioning system.

Background technique

At present, there is a three-way valve used in the air conditioning system on the market. The solenoid valve is controlled by a ball valve, which has a complex structure. After a period of operation, the control of the ball valve will not be in place, and the fluid will leak easily, causing work to stop and reducing the working efficiency of the air conditioner. .

Utility model content

The purpose of the utility model is to provide a three-way valve with simple structure and good sealing performance.

The technical solution adopted by the utility model to solve the technical problem is: a three-way valve, including a valve seat, one side of the valve seat is provided with an inlet, and the other side is provided with two outlets, and the valve seat A slider that can slide horizontally is provided inside, and a solenoid valve is provided outside the valve seat, and a control device is connected to the solenoid valve, and the solenoid valve is respectively connected to both ends of the valve seat and the inlet through three capillary tubes.

The beneficial effects of the utility model are: the conduction of the three capillaries is controlled by the solenoid valve, a pressure difference is formed at both ends of the slider, and the slider is driven to slide left and right, thereby forming two different channels, and realizing the direction of the fluid in the valve seat. Control, simple structure, good sealing.

Detailed ways

Below in conjunction with accompanying drawing, the utility model is described in further detail.

Referring to Figure 1 and Figure 2, a three-way valve includes a valve seat 1, one side of the valve seat 1 is provided with an inlet 3, and the other side is provided with two outlets 4, the valve seat 1 A slider 2 that can slide horizontally is provided inside, and a solenoid valve 5 is provided outside the valve seat 1, and a control device 7 is connected to the solenoid valve 5, and the solenoid valve 5 is respectively connected to the valve seat 1 through three capillary tubes 6. Both ends and the inlet 3, the conduction of the three capillary tubes 6 is controlled by the solenoid valve 5, and a pressure difference is formed at both ends of the slider 2 to drive the slider 2 to slide left and right. When the slider 2 is in the middle position of the valve seat 1, the inlet 3 Blocked by the slider 2, the three-way valve cannot work. When the slider 2 is on the left side, the outlet 4 on the left is blocked by the slider 2, and the inlet 3 and the outlet 4 on the right are connected to form a channel and generate flow. When the slider When the block 2 is on the right side, the outlet 4 on the right is blocked by the slider 2, and the inlet 3 and the outlet 4 on the left are connected to form channel 2 and generate flow. Therefore, the sliding direction of the slider 2 can be controlled to select channel 1 or channel 2. , to realize the direction control of the fluid in the valve seat 1.

The above-mentioned embodiments only illustrate the principles and effects of the present utility model, as well as the partially used embodiments. For those of ordinary skill in the art, without departing from the inventive concept of the present utility model, some Deformation and improvement, these all belong to the protection domain of the present utility model.
