Benefits of technology
The present invention provides a simplified proportional valve body with two cavities and two sealing elements. The valve body can be manufactured using extrusion molding, reducing defects and improving yield. The manufacturing method is efficient and allows for batch manufacturing with saved materials. The technical effect is an improved manufacturing process for proportional valves.
Problems solved by technology
Through repeated researches, the inventor finds that the proportional valve body in the prior art can only be die-casted because its internal structure is complex and irregular.
Thus only complex manufacturing methods such as die-casting can be used for the proportional valve body.

The present disclosure discloses a proportional valve body, a proportional valve and a manufacturing method for a proportional valve body. The proportional valve body comprises a body extending in an axial direction, the body being provided with a first cavity and a second cavity penetrating therethrough in the axial direction and isolated from each other; the body being further provided with a first through hole penetrating through an outer wall of the body, the first hole being communicated with the first cavity and isolated from the second cavity. In the present disclosure, the first cavity and the second cavity of the proportional valve body penetrate through the body in the axial direction, thus the general structure of the proportional valve body can be obtained by means of extrusion molding. Extrusion molding has the advantages of easy operation, high productivity, and high utilization ratio of raw materials. And the proportional valve body obtained by means of extrusion molding has favorable structural and mechanical properties.
Description
CROSS-REFERENCES TO RELATED APPLICATIONS[0001]This application claims the priority of Chinese Patent Application No. 201510084656.0 filed on Feb. 16, 2015, and the above application is incorporated herein by reference.TECHNICAL FIELD[0002]The present disclosure relates to a flow rate control device, and in particular, to a proportional valve body, a proportional valve and a manufacturing method for a proportional valve body.BACKGROUND ART[0003]In the technical field of gas appliances, a proportional valve is usually used for controlling a flow rate of fuel gas, thus controlling a volume of fuel gas entering a gas appliance.[0004]Chinese utility model patent No. 200520115076.5 discloses a proportional valve, comprising a first valve body and a second valve body, wherein the first valve body is provided with an inlet from which fuel gas enters, and the second valve body is provided with an outlet from which fuel gas enters into a combustion system; the first valve body is mounted with...
