Improved valve body assembly

Abstract

The invention discloses an improved valve body assembly. The improved valve body assembly comprises a plug valve, an electromagnetic valve and a nozzle. The plug valve, the electromagnetic valve and the nozzle are integrated into an integral structure. The plug valve comprises a plug valve rod and a plug valve element which are in linkage fit. An inner air cavity of the plug valve element communicates with an outer gas source. The wall of the inner air cavity of the plug valve element is provided with a first air hole and a second air hole. The first air hole communicates with the nozzle through a first air passing channel integrated on the valve body assembly in the work state. The electromagnetic valve comprises a movable electromagnetic valve air door and further comprises an electromagnetic valve inner air cavity and an electromagnetic valve outer air cavity which are isolated through the movable electromagnetic valve air door. The electromagnetic valve inner air cavity communicates with the second air hole of the plug valve element through a second air passing channel integrated on the valve body assembly, and the electromagnetic valve outer air cavity communicates with the first air passing channel in a converging manner through a third air passing channel integrated on the valve body assembly. By means of the improved valve body assembly, electric intelligent adjustmentbetween soft fire and big fire can be achieved, manual control is not needed, and convenience and accuracy are achieved. Meanwhile, the structure is compact, small and exquisite, and safety, practicability and reliability are achieved.

Description

technical field [0001] The invention relates to a valve body, which belongs to the technical field of safety valves, in particular to a valve body assembly applied to gas products. Background technique [0002] At present, the plug valve is the most widely used valve body structure on gas-fired stoves or stoves. The general structure of this type of plug valve includes a plug valve stem and a plug valve core. There are a number of air holes of different sizes on the inner wall of the plug valve core. The plug valve core can be driven to rotate by manually turning the plug valve stem. Therefore, it is possible to adjust the communication between different air holes and nozzles, so that the stove or stove can be adjusted and switched between low fire and high fire to realize firepower adjustment. However, this structural method is a manual adjustment structure, and the adjustment of each firepower needs to be controlled manually, which cannot meet the requirements of intellig...

AI Technical Summary

Problems solved by technology

However, this structural method is a manual adjustment structure, and the adjustment of each firepower needs to be controlled manually, which cannot meet the requirements of intelligence, and sometimes the adjustment and control are not accurate and timely enough, which may easily cause waste of gas resources and cause some fire accidents

Although there are some gas cookers or stoves with intelligent control of firepower on the market, the corresponding valve body structures are relatively complicated, the degree of integration is not high, and the product assembly and connection are not convenient enough.
