Problems solved by technology

[0002] In the prior art, the electric needle valve includes a valve body and a valve needle arranged in the valve body. The valve body is provided with a solenoid valve to control the movement of the valve needle. Action, the valve needle cannot stay at any position between the maximum position and the minimum position, resulting in the electric needle valve can only realize the opening and closing function, and cannot effectively and controllably adjust the flow rate

Embodiment Construction

[0021] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0022] see Figure 1-Figure 4 , the new type of electric needle valve includes a valve body 1 with a water inlet channel 11, an adjustment channel 12, and a water outlet channel 13 connected in sequence. The valve body 1 is provided with a valve needle 2 and is used to drive the valve needle 2 to move back and forth. The motor 3 that changes the water flow of the adjustment channel 12, the valve needle 2 is provided with a tapered needle 21 that is movably connected to the water inlet of the adjustment channel 12, and the other end is provided with a screw groove 22, and the motor 3 is provided with a threaded shaft corresponding to the screw groove 22 31, the threaded shaft 31 is movably connected with the screw groove 22.

[0023] By changing the taper of the tapered needle 21, the adjustment range of the water flow of the electric needle valve can b...

Abstract

A novel electric needle valve comprises a valve body. The valve body is provided with a water inlet channel, a regulation channel and a water outlet channel, wherein the water inlet channel, the regulation channel and the water outlet channel sequentially communicate. The valve body is provided with a valve needle and a motor used for driving the valve needle to move back and forth so as to regulate the water flow of the regulation channel. A conical needle head movably connected with a water inlet of the regulation channel is arranged at one end of the valve needle, and a screw groove is formed in the other end of the valve needle. A motor is provided with a threaded shaft in the manner that the threaded shaft corresponds to the screw groove. The threaded shaft is movably connected with the screw groove. The electric needle valve is reasonable in structure and accurate in flow regulation.

Description

technical field [0001] The invention relates to a novel electric needle valve. Background technique [0002] In the prior art, the electric needle valve includes a valve body and a valve needle arranged in the valve body. The valve body is provided with a solenoid valve to control the movement of the valve needle. Action, the valve needle cannot stay at any position between the maximum position and the minimum position, resulting in the electric needle valve can only realize the opening and closing function, and cannot effectively and controllably adjust the flow rate. [0003] Therefore, further improvements are required. Contents of the invention [0004] The purpose of the present invention is to overcome the shortcomings of the prior art and provide a new type of electric needle valve with reasonable structure and precise flow regulation. [0005] The purpose of the present invention is achieved like this: [0006] A new type of electric needle valve, including a va...
