The invention provides a proportional valve. A containing cavity is formed in a valve body, and is averagely divided into a plurality of segments of single cavities from top to bottom, an extension cavity is formed in the upper portion of each single cavity, a divided inlet and an outlet are symmetrically formed in the position, on the two sides of the middle of each single cavity, of the valve body, and a valve element comprises a plurality of single cores which are stacked from top to bottom, the single cores are fixed in a penetrating-connection manner through a string rod, the top end of the string rod is connected to an output shaft of a drive motor, and each single core comprises a work single core and a seal single core; each single core is provided with a core body, wherein the core body is contained in the corresponding single cavity; an annular extending edge is arranged on the upper portion of each core body, and is contained in the corresponding extension cavity; a runner is arranged on a core main body of each work single core, and when one end of each runner is aligned with the corresponding divided inlet, the other end of the runner is aligned with the corresponding outlet; a buffer cavity is formed in the valve body, the lower portion of the buffer cavity is communicated with the divided inlets, a main inlet is formed in the side face of the buffer cavity, and an air outlet is formed in the upper portion of the buffer cavity; the maximum flow of the proportional valve can be adjusted, the proportional valve can be applied to occasions with various flow needs, and the requirement of the flow control precision can be met.
Description
technical field [0001] The invention relates to the technical field of valves, in particular to a proportional valve. Background technique [0002] A proportional valve is a variable flow valve that can output a continuous flow range. A proportional valve can provide a regulated fluid flow that varies from zero flow to the maximum flow of the valve. However, the maximum flow rate of the valve is fixed and cannot be changed. In some application fields, when the demand for the maximum flow rate is not large, the existing proportional valve with a larger maximum flow rate can be used, but this will reduce the accuracy of flow control. Using a new proportional valve will increase the cost and cause waste of existing equipment. Contents of the invention [0003] The invention proposes a proportional valve, which solves the problem in the prior art that the maximum flow rate of the proportional valve is fixed and cannot be changed. [0004] Technical scheme of the present inve...
