Description

Constant-temperature water mixing valve

Technical Field

The utility model relates to a mix the water valve, in particular to mix water valve with constant temperature.

Background

The mixing valve is a water heating device which mixes cold water and hot water and outputs warm water. The existing high-end water mixing valves are all provided with temperature sensing elements, and the mixing proportion of cold water and hot water is automatically adjusted through the difference value between the outlet water temperature of mixed water and the set temperature, so that the outlet water temperature is in a basically constant state.

Chinese patent No. 201010284749.5 discloses an automatic thermostatic water mixing valve which adjusts the inflow of cold and hot water simultaneously by the axial sliding of a valve plug. Valve plug sliding fit is at muddy water valve body inner chamber, and the valve plug is generally made by the metal (use copper usually), has great clearance between valve plug and the muddy water valve body, seals through the sealing washer of installing in the valve plug middle part outside between valve plug and the muddy water valve body inner chamber.

The valve plug using this structure has some problems during use:

1. the valve plug made of metal is easy to generate scale and rust in the using process, and easy to generate the clamping stagnation phenomenon of the valve plug in the long-term using process, especially in places with poor water quality and high hardness;

2. in order to ensure the sliding and sealing between the valve plug and the inner cavity of the water mixing valve body, the fit clearance between the valve plug and the inner cavity of the water mixing valve body is large, solid particles mixed in water easily enter the clearance, and the sealing ring is sleeved outside the valve plug, so that impurity deposition easily occurs in the clearance on the upper side of the sealing ring, and the sliding of the valve plug is influenced;

3. the sealing washer is rubber material generally, and the sealing washer soaks in the aquatic for a long time, can take place the inflation, influences the slip of valve plug, and the sealing washer also can take place great wearing and tearing between impurity at the long-time slip in-process of valve plug simultaneously, influences sealing performance.
