Problems solved by technology

[0003] In the prior art, although the control valve can realize the function of diversion, the existing valve core only includes the groove opened in the valve core. During the long-term use of the valve, the valve core and the water outlet pipe are in constant contact and friction, and the wear of the valve core is large, resulting in a large gap between the valve core and the water outlet pipe, which affects the sealing performance of the control valve

Embodiment Construction

[0022] The following are specific embodiments of the present invention and in conjunction with the accompanying drawings, the technical solutions of the present invention are further described, but the present invention is not limited to these embodiments.

[0023] Such as Figure 1 to Figure 4 As shown, the three-way control valve includes a valve body 100, on which an outlet pipe joint 400, an inlet pipe joint 300, and a spool 200 movable in the valve body 100 are arranged; 210; a knob 500 connected to the valve core 200 is also provided on the valve body 100, and a cover plate 700 threadedly connected to the valve body 100 is also provided between the valve core 200 and the knob 500, and the cover plate 700 is pierced There are two ends of the spring 710 against the valve body 100 and the end surface of the knob 500 respectively. There is also a slot 720 on the cover plate 700. Pressing and turning the knob 500 can make the knob 500 snap into the slot 720 and make it The t...

Abstract

The invention provides a three-way control valve, belongs to the technical field of valves and solves the problem of poor sealing performance of an existing three-way control valve. The three-way control valve comprises a valve body, a water outlet pipe joint, a water inlet pipe joint and a valve spool are arranged on the valve body, the valve spool is movably arranged in the valve body, a channel is arranged on the valve spool, a knob connected with the valve spool is arranged on the valve body, a cover plate connected onto the valve body in a threaded manner is arranged between the valve spool and the knob, a spring penetrates the cover plate, two ends of the spring are abutted to end faces of the valve body and the knob respectively, a clamp groove is formed in the cover plate, the knob is pressed and rotated to be clamped in the clamp groove, and two ends of the channel are communicated with the water inlet pipe joint and the water outlet pipe joint respectively, so that the water inlet pipe joint is communicated with the water outlet pipe joint. The three-way control valve has the advantages of fine sealing performance and flow guide effect.

Description

technical field [0001] The invention belongs to the technical field of valves and relates to a three-way control valve. Background technique [0002] Control valve, also known as regulating valve, is widely used in daily life and industrial production as the main actuator. It can change the direction of the medium in the pipeline by receiving the control signal output by the regulating control unit, and also plays a role in cutting the flow of the medium. , diversion and confluence; control valves are generally composed of actuators and valve body components. According to the power source of the actuators, control valves can be divided into three types: pneumatic, electric, and hydraulic. According to the difference of the spool, the control valve It can be divided into T-type control valve and L-type control valve. [0003] In the prior art, although the control valve can realize the function of diversion, the existing valve core only includes the groove opened in the valv...
