Description

Check valve

The present invention relates to a check valve used for a water purifier or a hot / cold water purifier, and includes a spring creep coupled to a flow rate, an inlet and an outlet tube, and a groove, and includes a spring pressurized plunger and a plunger in a cylindrical housing configured to be separated up and down. It is characterized by comprising a silicon ring corresponding to the bottom surface, the inner ring and the outer ring supported by the valve to form a central flow path of the silicon ring, and the flow rate dispersion flow path is arranged on the valve.

CHECK VALVE, which uses a conventional silicone ring, is a silicone ring, a plunger, and a spring inserted into a housing. The plunger moves when the outside and the inside of the silicone ring are separated. Center deviation) and when the valve is inclined, leakage occurs because the contact between the opening and closing surface of the plunger is not constant.

If the cause of leakage is observed in detail, the contact between the opening and closing surfaces of the housing and the silicon ring is irregular in the valve in which the silicone ring is separated from the plunger, and in the case of the valve in which the silicone ring is attached to the plunger, leakage occurs due to the center deviation of the plunger opening and closing operation. do. In addition, if the supporting valve is made on the main surface of the silicon ring, the vortex phenomenon occurs inside the silicon, causing the flow backflow and noise. Backflow occurs.

The object of the present invention is to provide a check valve in which noise, chattering and flow rate backflow do not occur, and in particular, it constitutes a flow distribution channel installed in a valve and a valve supported by an outer ring on silicon corresponding to an opening / closing plunger. It is characterized by.

This invention is described in detail according to the accompanying drawings as follows.

A plunger pressurized by a spring 6 in the cylindrical housings 2 and 3, each having a spring creep 5 coupled to the flow rate injection pipe 2 'and the discharge pipe 3' and the groove 4 and configured to be separated up and down. (7) and an outer ring (13) having a silicon ring (1) corresponding to the bottom surface of the plunger and supported by an inner ring (12) and a valve plate (14) forming a central flow path (11) of the silicon ring (1). The flow rate dispersion flow passage 15 is arranged on the valve 14.

This design inserts the spring 6 plunger 7 and the silicone ring 1 into the separate housings 2, 3 and assembles the housings 2, 3. The prefabricated sprinkler 5 is coupled to the groove 4.

If the check valve is installed after assembly, the fluid flows from the injection pipe 2 'in the direction of the discharge pipe 3' and backflow is prevented. When a fluid having a positive pressure is applied to the injection pipe 2 ', the fluid pressure pushes the plunger 97 to open the flow path, and when the hydraulic pressure of the injection pipe 2' is lost, the spring 60 causes the plunger 6 to be silicone ring (1). ) To block backflow.

In this design, when the valve is opened by the positive pressure, the fluid passes through the central passage 11 inside the inner ring 12 of the silicon ring 1, and when the valve is closed, the plunger 7 moves the inner ring 12 to the bottom of the housing 2. In close contact with the surface is to block the central flow path (11).

In this design, the valve 14 supports the outer ring 13. By this structure, the inner ring 12 can always be kept in the correct position, so that the opening and closing operation of the valve is made accurately. In addition, since the flow distribution channel 15 is distributed on the valve 14 supporting the outer ring 13, it is possible to prevent chattering and noise generation of the silicon ring 1 when the static pressure is generated or when the static pressure is changed to negative pressure.

As such, this design prevents the silicon ring from noise, chattering and dislocation, thus providing a check valve that opens and closes the flow path accurately at all times.
