Continuously adjustable throttle valve

Abstract

The invention relates to the technical field of throttle valve mechanical manufacturing and in particular to a continuously adjustable throttle valve which comprises a water inlet tube and a water outlet tube. The continuously adjustable throttle valve is characterized in that a flow adjusting tube is arranged between the water inlet tube and the water outlet tube; two ends of the flow adjusting tube are connected with the outer sides of the water inlet tube and the water outlet tube in a sleeved manner with a micro gap; a sliding platform is arranged on an inner tube wall connected with the water outlet tube, of the flow adjusting tube; a chute is formed in the water outlet tube; the flow adjusting tube slides on the water inlet tube and the water outlet tube through the sliding platformand the chute; a baffle piece is arranged at the end part of the water outlet tube; the baffle piece consists of an annular piece and a central piece; the annular piece is connected with the central piece through a support rod; a conical spring piece is arranged inside the flow adjusting tube; the opening end of the conical spring piece is arranged at the water inlet end of the flow adjusting tube; and the sharp end of the conical spring piece is connected with the central piece of the baffle piece. The continuously adjustable throttle valve has the advantages of being simple in structure, large in flow adjustment range, smooth in flow pressure difference variation, simple and convenient to operate, and the like.

Description

technical field [0001] The invention relates to the mechanical manufacturing technical field of a throttle valve body, in particular to a continuously adjustable throttle valve with simple structure, large flow adjustment range, smooth flow pressure difference change and easy operation. Background technique [0002] As we all know, a throttle valve is a valve that controls fluid flow by changing the throttle area or throttle length. The throttle valve in the prior art generally includes a valve body, a valve core and a regulating rod. The valve core is set in the valve body, and the adjusting rod is used to adjust the position of the valve core in the valve body, so as to adjust the liquid flow in the valve body. The general change process of the existing throttle valve is In the process, the flow and pressure difference changes abruptly, and pressure is generated on the throttle valve, and the practical life is shortened, and the flow control is generally realized by adjust...

[0002] As we all know, a throttle valve is a valve that controls fluid flow by changing the throttle area or throttle length. The throttle valve in the prior art generally includes a valve body, a valve core and a regulating rod. The valve core is set in the valve body, and the adjusting rod is used to adjust the position of the valve core in the valve body, so as to adjust the liquid flow in the valve body. The general change process of the existing throttle valve is In the process, the flow and pressure difference changes abruptly, which will generate pressure on the throttle valve, and the practical life will be shortened, and the flow control is generally realized by adjusting the spool and the adjusting rod, and the use of the flow cannot be precisely controlled.
