Description

Ceramic valve with middle section for cold water supply

technical field

The utility model relates to a ceramic valve, in particular to a ceramic valve with the function of supplying cold water in the middle section.

Background technique

In recent years, relevant industries and users have attached great importance to the safety of cold and hot dual-temperature faucets (hereinafter referred to as dual-temperature faucets), and "anti-scalding" is a very important point. Based on this, the relevant industries have developed a variety of The structural shape of the dual-temperature faucet with anti-scald function, for example, a stop structure is set on the cold and hot water temperature switching path, so that the user needs to exert more force when switching to the hot water mode.

The dual-temperature faucet structure currently available on the market, when the handle is placed in the middle position, if the user pulls up the handle at this position, the default temperature of the water supply is not cold water, but a mixed state of cold and hot water. Although this state has been developed for a long time in the structural design of the dual-temperature faucet product, we have found that there are some problems and hidden worries in the use of this structural form. It is in the state of supplying cold water, and the user can achieve it by first turning the handle to the cold water position and then pulling it up. However, the design considerations for anti-scalding obviously need to consider more possibilities of scalding more intimately. , assuming that the user inadvertently or unknowingly (such as young children, the elderly, etc.) pulls up the handle at the middle position, it should be in a state of warm water with evenly mixed cold and hot water, but in fact it is unstable Factors exist, for example, when the water supply pressure at the cold water end is weak, it will directly switch to the hot water mode. In this case, there is a risk of scalding the user; moreover, the warm water mode and the hot water mode of the dual-temperature faucet are determined by the handle. The swing angle is only a few degrees, and the user will switch to the hot water mode if he moves or hits a little, which is one of the reasons that may cause burns; on the other hand, when the user pulls the handle in the middle position, due to Both the cold and hot water inlet channels are only partly opened, so for the hot water part, the water pressure may not meet the gas ignition standard due to insufficient water pressure, which may easily cause gas leakage.

To put it another way: when the handle of the dual-temperature faucet is returned to its original position, the user can of course return it to the cold water orientation position first, and when using it next time, directly pull up the handle to enter the cold water supply state; however, based on visual Beautiful balance, most users will habitually return the handle to the middle position after turning off the faucet, especially for restaurants, homestays and other commercial places that pay attention to service quality and customer perception, when the service personnel tidy up the bathroom equipment in the room , the handle of the double-temperature faucet is often returned to the middle position, so it is quite difficult to change this habit of people. Therefore, if the internal ceramic valve structure of the double-temperature faucet can be improved to overcome the The aforementioned problems should be ideal and feasible solutions.
