Problems solved by technology

However, the water valve in the related art relies on the structure at the tail of the valve body to achieve throttling, which makes the flow rate of the memory alloy valve larger and the turbulent flow larger, which easily causes the sound of the pipeline to be louder

Embodiment Construction

[0039] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals represent the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the figures are exemplary and are intended to explain the present invention and should not be construed as limiting the present invention.

[0040] In a commonly used memory alloy valve, water flows in from the flow measuring impeller, passes through the valve core 20, and flows out from the valve seat 30. Among them, the flow measuring impeller assembly is mainly used to measure the water flow in the valve. The valve core 20 and the valve seat 30 form an orifice to realize throttling. The spring 40 is a memory alloy material. Under force, the opening degrees of the valve core 20 and the valve seat 30 are different to realize the change of t...

Abstract

The invention discloses a water valve and gas equipment provided with the same. The water valve comprises a valve body, a valve element, a valve seat, a spring and a pressure reducing structure, wherein a valve cavity is defined by the valve body, a water inlet is formed in one axial end of the valve body, a water outlet is formed in the other axial end of the valve body, and the water inlet and the water outlet communicate through the valve cavity; the valve element is arranged in the valve cavity, and a water channel communicating with the valve cavity is defined by the valve element; the valve seat is arranged in the valve cavity and located at the downstream side of the valve element, and the valve seat is provided with a valve plug opposite to an axial outlet of the water channel; thespring is arranged on the valve element in a sleeving mode and used for adjusting the distance between the valve plug and the axial outlet; and the pressure reducing structure is arranged in the valve cavity and located at the upstream side of the valve element, and the pressure reducing structure plays a role in throttling and depressurizing water flow in the valve cavity. According to the watervalve in the embodiment, by arranging the pressure reducing structure, the flow velocity of the water flow can be reduced to achieve the flow stabilizing effect, the forward impact of the water flowon the spring is lowered, the stability of the spring in the valve cavity is improved, the stretching and contracting amount of the spring is adjusted according to water temperature, and then the opening degree of the water valve is accurately adjusted through the spring to guarantee the stability of the flow velocity of the water valve.

Description

technical field [0001] The invention relates to the technical field of household appliances, in particular to a water valve and a gas appliance with the same. Background technique [0002] When the gas water heater is in use, the pressure fluctuation of the water pipe will cause the water flow in the water pipe to fluctuate significantly, making the outlet water temperature unstable. In order to solve such problems, the gas water heater is designed with a memory alloy temperature control valve, which will adjust the opening of the water valve according to the change of temperature to meet the hot water requirements. But the water valve in the related art relies on the structure of the valve body tail to realize throttling, so that the flow rate of the memory alloy valve is relatively large, and the turbulent flow is also relatively large, which easily causes the sound of the pipeline to be relatively large. Contents of the invention [0003] The present invention aims to ...
