Water valve outlet canal structure of water-gas ganged valve

Abstract

The invention discloses a water valve drainage channel structure of a moisture interstage valve, comprising a drainage channel provided over the water valve body and communicated with a water storage cavity within the water valve body; characterized in that an individual one-way controlled pressure valve core is arranged on the drainage channel; the valve core comprises a bonnet that can slide within the drainage channel and a reset spring that is provided at the tail end of the bonnet and is located within the drainage channel, the top of the bonnet is blocked off in top pressure at a water inlet of the drainage channel by means of the reset spring. The invention individually controls the starting water pressure by arranging the individual one-way controlled pressure valve core on the drainage channel, thus realizing starting up a gas water heater with ultralow pressure water streams. The invention is simple in structure, low in the starting water pressure, suitable for the water valve drainage channel structures of the moisture interstage valves in a variety of the gas water heaters.

Description

Water outlet channel structure of the water-gas linkage valve technical field The invention relates to the field of gas water heaters, in particular to an improved water valve structure of a water-gas linkage valve for a gas water heater. Background technique At present, such as patent application number 200520120025.1, the Chinese patent titled "Improved Water-Air Linkage Valve" discloses an improved water-air linkage valve including a water valve, a connecting piece, an elastic sealing sheet, a water inlet pipe, and a connecting The micro switch in the part, the joystick of the micro switch is located in the diaphragm of the connecting part, the elastic sealing piece is located between the diaphragm of the connecting part and the diaphragm of the water valve, and the water pressure regulator is installed at the water inlet of the diaphragm of the water valve At the water valve membrane disc, there is also a water hole communicating with the water valve, and a plug is pro...

Problems solved by technology

However, in this structure, when water enters the water storage chamber space between the elastic sealing sheet and the water valve diaphragm chamber, the water pressure will drive the plug to open while pressing the elastic sealing sheet to move to the left. The gap of the gas is increased, so that the discharge flow is large when the water pressure is low, so that the pressure in the water storage chamber is not easy to be maintained under low pressure. In this way, the water pressure of the gas start-up must still be relatively high.
