A water flow steady flow valve and a gas water heater using the valve

Abstract

The invention relates to a water flow stabilizing valve and a gas water heater using the valve, wherein the water flow stabilizing valve includes a pipe body, the lower part of the pipe body is provided with a water inlet, and the upper part is provided with a water outlet; In the pipe body, the partition plate is provided with a water outlet connecting the water inlet and the water outlet; the adjustment plate is located below the partition board and is set against the partition board, and the adjustment board is provided with a water outlet that can correspond to or stagger the water outlet. the water hole; the guide column is vertically arranged in the pipe body, and the outer peripheral wall of the guide column is provided with a guide groove extending spirally along its axial direction; the first plate body is located under the adjustment plate and the two are linked together, The first plate body is provided with a guide block placed in the guide groove, and the first plate body can move upward relative to the guide column under the action of water flow; the first elastic member acts on the first plate body, Keep the first plate body moving downward to play the role of steady flow.

Description

technical field [0001] The invention relates to a flow stabilizing device, in particular to a water flow stabilizing valve and a gas water heater using the valve. Background technique [0002] Installing a water flow stabilization device in the gas water heater water system can effectively improve the temperature fluctuation of the hot water outlet caused by the fluctuation of the water flow, and improve the user's experience of using the gas water heater. 5.2.2.4.6 requirements in GB6932-2015 "Household Gas Instant Water Heater": The water system should be equipped with a flow stabilization or flow adjustment device. With the continuous increase of high-rise buildings, the water pressure of users' homes is becoming more and more complicated. In some communities, the water pressure is high and the water pressure fluctuates greatly, which brings certain troubles to the use of existing gas water heaters. The development of a convenient and adjustable flow stabilization device...

[0004] However, this patent can only achieve one-stage steady flow through the movement of the valve core, and its steady flow pressure range is limited. If the pressure reaches the steady flow limit of the steady flow device, the valve core can no longer move, and the steady flow device cannot Continue to play the role of steady flow

[0005] In addition, because the lower seat (equivalent to the first plate below) can move relative to the outer casing (equivalent to the valve body below), there is a gap between the outer peripheral wall of the lower seat and the inner peripheral wall of the outer casing, so that water will flow from Flow through the gap between the outer peripheral wall of the lower seat and the inner peripheral wall of the housing will result in insufficient accuracy of steady flow
