Abstract

A quantitative valve for liquid, comprising a valve body, a quantitative cavity, a hole valve core and a groove valve core, the quantitative cavity is connected to the valve body, the groove valve core is provided with a pair of communicating grooves along the radial direction, and the hole valve core is divided along the circumference. There are two sets of through holes in the two circles, and two pairs of through holes in each group are set opposite to each other in the radial direction. The through holes in the inner ring communicate with the quantitative cavity through the holes on the valve body, and the through holes in the outer ring are connected with the valve body respectively. The corresponding vent hole, liquid inlet hole, air pressure balance hole and liquid outlet hole are connected. The invention has the advantages of simple and reasonable structure, good manufacturability, high yield, low cost, safe and convenient use, etc., and can be used as a dosing valve for liquid fuel stoves or other liquid dosing equipment.

Description

technical field [0001] The invention relates to a valve, specifically a liquid quantitative valve. Background technique [0002] The liquid quantitative valve provided by the current technology CN982500386 solves the quantitative problem of the preheating fuel of the alcohol-based fuel stove, and ensures the safe and convenient use of the stove. However, its structure can be further simplified, and the manufacturability and yield rate of processing and assembly still need to be further improved. Contents of the invention [0003] The object of the present invention is to design a liquid quantitative valve with simple and reasonable structure, good manufacturability, high yield, and safe and convenient use. [0004] The purpose of the present invention is achieved through the following technical solutions, which specifically include a valve body, a quantitative chamber, a hole valve core and a groove valve core, the hole valv...
