Description

A flow valve used in washing machine

technical field

The utility model relates to a flow valve, in particular to a flow valve used in a washing machine.

Background technique

The existing garden cleaning machines have low working pressure and high flow rate, so flow valves are needed to control the on-off of the circuit through the size of the flow rate. However, the flow valve has a complex structure and has no check protection function, so that the water in the system can easily flow back into the water inlet system when the gun is turned off.

Contents of the invention

The purpose of the utility model is to provide a flow valve with low cost and a check protection function.

The technical scheme of the utility model is: a flow valve used in a washing machine, which at least includes a valve body with a valve cavity, a reed switch located outside the valve body, a magnet embedded in it and a valve that can move in the valve cavity spool.

The utility model further includes a spring baffle fixed in the valve body, and a spring capable of reciprocating linearly in the valve cavity and one end of which is fixed on the spring baffle, and the other end of the spring is connected with the valve core.

The valve body in the utility model includes a water outlet end and a water inlet end.

The spring baffle in the utility model is close to the water outlet side, and includes a water outlet hole communicating with the valve cavity, and the water inlet end communicates with the valve cavity through a water inlet hole.

The utility model further includes an O-shaped sealing ring sleeved on the valve core.

The valve chamber in the utility model has an inner cone surface which is sealingly matched with the O-shaped sealing ring near the water inlet hole.

The utility model advantage is:

The structure is simple, the reliability is higher, and the water backflow of the water equipment is prevented, and the cost is low.

Detailed ways

Embodiment: First, as shown in FIG. 1 , the utility model provides a specific embodiment of a flow valve used in a cleaning machine, which at least includes a valve body 1 with a valve cavity 10 and a reed located on the outside of the valve body 1 Tube 2, a spring baffle 3 fixed in the valve body 1, a spring 4 that can move back and forth in the valve cavity 10 and one end is fixed on the spring baffle 3, and the other end of the spring 4 is connected with a magnet 5 embedded in it. The spool 6 and the sealing ring 7 located on the spool 6, wherein the valve body 1 includes the water outlet 12 (or called the A end) and the water inlet 14 (or called the B end), the water outlet 12 passes through the spring baffle 3 The water outlet hole 30 communicates with the valve chamber 10, and the water inlet 14 communicates with the valve chamber 10 through a water inlet hole 140. The valve chamber 10 has an inner tapered surface 100 sealingly fitted with the valve core 6 near the water inlet hole 140. , The sealing ring 7 is an O-ring.

As shown in Figure 2, when working, after the water outlet 12 is opened, under the impact of the water flow, the valve core 6 compresses the spring 4 to move to the left. The reed switch 2 is connected, and the washing machine starts. And after starting, because the water flow increases, the spring 4 continues to be pressed to the limit. In the process that the spring 4 continues to be compressed, the reed switch 2 is always within the range of action of the magnet 5, so the power circuit of the whole washing machine remains connected all the time.

As shown in Figure 3, when the water outlet 12 is closed suddenly, the spool 6 moves to the right under the action of the spring force, and when the reed switch 2 breaks away from the magnetic field of the magnet 5, the reed switch 2 is disconnected, and the washing machine stops working. The valve core 6 continues to move to the right until the sealing ring 7 contacts the inner cone surface 100 of the valve cavity 10 to form a seal, thereby preventing the water in the water equipment from flowing back through the water inlet hole 140 .

By adopting the embodiment of the utility model, the structure is simple, the reliability is higher, and the water backflow of the water equipment is prevented, and the cost is low.

Of course, the above-mentioned embodiments are only to illustrate the technical concept and characteristics of the present utility model, and its purpose is to allow people familiar with this technology to understand the content of the present utility model and implement it accordingly, and cannot limit the protection scope of the present utility model with this. All equivalent transformations or modifications made according to the spirit of the main technical solutions of the utility model shall fall within the protection scope of the utility model.
