Water flow stabilizing valve and gas water heater applying same

Abstract

The invention relates to a water flow stabilizing valve and a gas water heater applying the same. The water flow stabilizing valve comprises a pipe body, a partition plate, an adjusting plate, a guidecolumn, a first plate body and a first elastic piece. A water inlet is formed at the lower portion of the pipe body, and a water outlet is formed at the upper portion of the pipe body. The partitionplate is transversely arranged in the pipe body, and a water passing opening communicated with the water inlet and the water outlet is formed in the partition plate; the adjusting plate is located below the partition plate and attached to the partition plate, and a water passing hole capable of corresponding to or being staggered from the water passing opening is formed in the adjusting plate; theguide column is vertically arranged in the pipe body, and a guide groove spirally extending in the axial direction of the guide column is formed in the peripheral wall of the guide column; the firstplate body is located below the adjusting plate and fixedly connected with the adjusting plate, a guide block arranged in the guide groove is arranged on the first plate body, and the first plate bodycan move upwards relative to the guide column under the action of water flow; and the first elastic piece acts on the first plate body, so that the first plate body keeps a downward moving trend, anda flow stabilizing effect is achieved.

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
