Pulling bar controlled type dual-linkage freeze-prevention ceramic valve

Abstract

The invention discloses a pulling bar controlled type dual-linkage freeze-prevention ceramic valve which comprises a base, a control part, and a switching part, wherein at least four channels are arranged on the plane of the base; the control part is fixedly arranged on the upper end of the base and consists of a static plate and a movable plate, five holes are formed in the plane of the static plate and are respectively a cold water inlet hole, a cold water outlet hole, a hot water inlet hole and a hot water outlet hole which are respectively communicated with the four channels, and a drain hole which is not communicated with the four channels, a concave cavity is formed in the plane of the movable plate, and the movable plate is covered on the static plate in a slideable manner, and according to the relative sliding position, the five water holes are communicated in pairs through the concave cavity selectively; and the switching part is arranged above the control part so as to drive the movable plate to slide relative to the static plate. The pulling bar controlled type dual-linkage freeze-prevention ceramic valve facilitates the input and output of cold water and hot water independently, and the icing and freeze prevention problems in winter can be solved.

Description

technical field [0001] The invention relates to the field of ceramic valves, in particular to a pull-rod control double-linkage antifreeze ceramic valve capable of realizing independent input and output of cold and hot water, and capable of preventing freezing in winter. Background technique [0002] The jet pressurized faucet currently used in the market is characterized by using the Venturi principle, the cold water jet pumps hot water, and increases the flow of hot water. This structure requires separate control of the cold and hot water channels of the faucet. Although the ceramic spool in the prior art can achieve independent input and output of cold and hot water, the structure design of the spool is complicated, the sealing performance is not high, the precision of the body matched with the spool is high, the manufacturing cost of the faucet body is high, and the flow rate is high. Small, high pressure requirements. [0003] The spool plays the role of a start switch...

Problems solved by technology

Although the ceramic spool in the prior art can achieve independent input and output of cold and hot water, the structure design of the spool is complicated, the sealing performance is not high, the precision of the body matched with the spool is high, the manufacturing cost of the faucet body is high, and the flow rate is high. Small, high pressure requirements

[0003] The spool plays the role of a start switch during use. When the spool is closed, the passage between the faucet and the tap water is cut off. Because the spool itself has the ability to store water, there will be standing water in the spool; in northern my country In regions where the temperature is extremely low in winter, the water will freeze, and the water trapped in the valve core will freeze due to the low temperature, resulting in abnormal water use, and in severe cases, the valve core will freeze and crack
