Abstract

The invention relates to a vacuum blow-down valve which comprises a valve body, a main valve element assembly arranged in the valve body to switch on or off the valve body, and an inner valve elementassembly arranged in the main valve element assembly and used for achieving sealing and unsealing of the interior of the valve body. A communicating flow channel is formed in the valve body, and the interior of the valve body is used for intermittently introducing air or forming vacuum. The main valve element assembly is arranged in the valve body, and realizes telescopic movement towards one sideof the communicating flow channel through the ventilation state in the valve body. The inner valve element assembly is arranged on the side, deviating towards the communicating flow channel, of the main valve element assembly and used for achieving sealing between the end of the main valve element assembly and the inner wall of the communicating flow channel. A differential pressure driving technology is adopted for control, the streamline design of the communicating flow channel enables the circulation resistance to be minimum, the circulation efficiency to be maximum and the vacuum sewage conveying efficiency to be optimal, an air supplementing and noise reducing technology is adopted for active noise reduction, an inching active odor exhausting technology is adopted, and the higher functionality of the whole structure is achieved.

Description

technical field [0001] The present invention relates to the technical field of vacuum sewage collection, transportation and treatment, wherein the vacuum sewage collection technology refers to front-end devices or products that collect sewage at the source of sewage, including but not limited to various kitchens (such as toilets, urinals, shower rooms, etc.) , bathtubs, etc.) and sanitary products (such as vegetable sinks, dishwashers, etc.); vacuum sewage transportation technology refers to the related technologies that efficiently transport the sewage collected by front-end devices or products to sewage post-treatment equipment, including the core components There are vacuum pump stations, sewage collection tanks, underground (mainly arranged) vacuum conveying pipe network systems, vacuum wells, fault detection and diagnosis systems, etc.; vacuum sewage treatment technology refers to post-processing equipment or devices, the main function of which is to centrally collect Sew...
