Intelligent back pressure type energy-saving flushing valve

Abstract

The invention discloses an intelligent back pressure type energy-saving flushing valve, and belongs to the technical field of bathroom accessories. The flushing valve comprises a flushing valve main body, a motor, an electromagnetic valve and a constant pressure valve, wherein the constant pressure valve comprises a four-way water inlet connecting elbow, a gland and an end cover, an assembly spaceis formed in the four-way water inlet connecting elbow, a valve rod is installed in the assembly space, the head end of the valve rod is installed in the four-way water inlet connecting elbow throughthe gland, a lower pressing piece, a membrane, an upper pressing piece, a nut and a spring are sequentially arranged on the valve rod, a containing cavity is formed between the flushing valve main body and a valve body positioning water sealing cover, and a flushing valve assembly is arranged in the containing cavity. The size of the valve body is reduced, the installation is convenient, the flushing valve is suitable for different water qualities, the flow stability of the flushing valve in the operation process is kept, then noise pollution is reduced, meanwhile, the service lives of valvecore pieces are prolonged by adopting novel ceramic piece valve cores, in addition, a filter screen can be automatically washed, and thus the use convenience of the flushing valve is improved.

Description

technical field [0001] The invention relates to the technical field of sanitary products, in particular to an intelligent anti-pressure energy-saving flush valve. Background technique [0002] Smart flush toilets have become a necessity in society in daily life, but with the use of resources by social needs, resources are also decreasing with the development of society, and the various functional conditions of smart flush toilets are A very large system, the flush valve is one of the important components in the smart flush toilet. [0003] The existing smart toilet flush valves have the following disadvantages during use: 1. The valve body is large in size, requiring two valve bodies to be combined, and its structure utilization optimization rate is low; 2. Traditional smart toilet flush valves have high requirements for water quality , the scope of application is narrow; 3. The existing intelligent toilet flush valve has the problems of unstable flow and large noise during...

Problems solved by technology

[0003] The existing smart toilet flush valves have the following disadvantages during use: 1. The valve body is large in size, requiring two valve bodies to be combined, and its structure utilization optimization rate is low; 2. Traditional smart toilet flush valves have high requirements for water quality , the scope of application is narrow; 3. The existing intelligent toilet flush valve has the problems of unstable flow and large noise during operation; 4. The valve chip of the flush valve is made of traditional materials, and its service life is low. 5. The internal filter of the flush valve needs to be cleaned regularly, which is time-consuming and laborious, and increases the burden of use. Therefore, we propose a smart back pressure energy-saving flush valve
