Problems solved by technology

[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

Embodiment Construction

[0023] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0024] Figure 1 to Figure 10 As shown, a waterway switching valve includes a valve body 1 and a switch seat 2. The valve body 1 is provided with a water inlet channel 11 and a water outlet channel 12. The water outlet channel 12 of the valve body communicates with the middle of the valve body 1 from the outside. The water inlet channel 11 of the body communicates from the outside to the periphery and upper part of the water outlet channel 12 in the middle of the valve body 1, and an elastic seal 3 is installed in the valve body 1 above the water outlet channel 12 in the middle of the valve body 1;

[0025] The elastic seal 3 is composed of a disk-shaped diaphragm 31 and a circular reinforcing seat 32 set in the middle of the diaphragm 31. The edge of the diaphragm 31 is pressed between the valve body 1 and the switch seat 2. The rein...

Abstract

A water heater valve includes a valve body 1 and housing 2. The valve body 1 has inlet and outlet channels 11, 12. The outlet channel 12 is provided with an elastic seal 3 that has a control hole 324 aligned with the outlet channel 12, and a water hole 325 aligned with the inlet channel 11. The housing 2 is fitted to the valve body 1 above the elastic seal 3 and grips the periphery of the elastic seal 3. A plunger 4 carrying a closure plug 41 is movable downwards to seal the control hole 324 of the elastic seal 3 to thereby close off the outlet channel 12.

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...
