Water path switch valve

Abstract

The invention discloses a water path switch valve, comprising a valve body and a switch base. A water inlet channel and a water outlet channel are arranged on the valve body; the water outlet channel of the valve body is communicated to the middle of the valve body from the outside; the water inlet channel of the valve body is communicated to the rim and the upper part of the water outlet channel at the middle of the valve body from the outside; an elastic sealing piece is mounted on the water outlet channel in the middle of the valve body; a control through hole corresponding to the water outlet channel of the valve body and a water passing through hole corresponding to the water inlet channel of the valve body are arranged on the end face of the elastic sealing piece; the switch base is mounted on the valve body on the elastic sealing piece, and presses the edge of the elastic sealing piece; a pressing rod capable of moving the switch base upwards and downwards and positioning is mounted in the middle of the switch base; a sealing plug is mounted at the lower end of the pressing rod; and after the pressing rod is moved downwards in position, the sealing plug at the lower end can seal the control through hole of the end face of the elastic sealing piece, and drives the elastic sealing piece to seal the water outlet channel in the middle of the valve body. The water path switch valve provided by the invention has the advantages of low manufacturing cost, sensitive and labor-saving operation, and is applicable to the place which is usually opened and closed.

Description

technical field [0001] The invention relates to the technical field of electric water heater manufacturing, in particular to a water circuit switch valve applied to a fast electric water heater. Background technique [0002] Generally, ball valves, angle valves, solenoid valves and other products are common on-off valves used in waterways. Ball valves and angle valves require large torque during operation and are easily damaged when they are frequently opened and closed. They are generally used in occasions where they are not frequently opened and closed. , so it is not suitable for occasions that require frequent opening and closing, such as fast electric water heaters; and solenoid valves are suitable for frequent opening and closing. The risk of electric leakage will reduce the safety of using instant electric water heaters. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a waterway on-off valve, which has lo...
