Embodiment Construction

[0036] Please check Figure 1 to Figure 6 , a button switching three-way valve, which includes a fixed unit 100 and a button 200 . The fixing unit 100 has a water inlet 110 and two water outlets 120 , 130 , and a pilot valve 140 , 150 is connected between each water outlet 120 , 130 and the water inlet 110 . Each pilot valve 140,150 has a valve shaft 141,151, a pilot valve body 142,152, a spring 143,153, a rubber block 144,154 and a pilot spool 145,155, the pilot valve is In the prior art, the valve shafts 141, 151 are slidably connected to the fixing unit 100 up and down, and can slide between the upper, middle and lower control positions. By controlling the valve shafts 141, 151 to slide up and down, the pressure relief waterways of the pilot valves 140, 150 can be controlled (such as Figure 4 , 5 , Dotted line in 6, 7) whether to release pressure, whether to control the pilot valve to open through the pressure relief waterway, whether to control the outlet waterway 120,...

Abstract

The invention discloses a button switching three-way valve which comprises a fixed unit (100), wherein the fixed unit (100) is provided with a water inlet path (110) and two water outlet paths (120) and (130); pilot valves (140) and (150) are connected between the water outlet paths (120,130) and the water inlet path (110); the pilot valves (140) and (150) are provided with valve shafts (141) and (151); the on-off control between the water outlet paths (120) and (130) and the water inlet path (110) is realized by controlling the valve shafts (141) and (151) to slide; the fixed unit (100) is provided with two opposite control surfaces (161) and (162), and each of the two control surfaces (161) and (162) is provided with a clamping groove; the button switching three-way valve is also provided with a button (200) which is provided with a middle part and two connecting parts (210 and 220) which are positioned at both sides of the middle part; the middle part is pivoted at the fixed unit (100); the two connecting parts (210) and (220) are respectively connected with the two valve shafts (141) and (151) to control the two valve shafts (141) and (151) to slide; and the outer sides of the two connecting parts (210) and (220) are provided with clamping teeth which are adapted to clamping grooves. The invention has the advantage of convenience for switching.

Description

technical field [0001] The invention relates to a push-button switching three-way valve. Background technique [0002] The existing three-way valve includes a body and a spool. The body has a water inlet and two water outlets, and the two outlets can be connected to the water inlet. The spool is rotatably connected in the body, and through the relative rotation between the spool and the body, the two water outlets are switched and connected to the water inlet. The use of the above-mentioned rotating valve core to realize waterway switching has the following disadvantages: the required switching force is large and the switching is inconvenient. Contents of the invention [0003] The present invention provides a push-button switching three-way valve, which overcomes the disadvantages of large switching force and inconvenient switching existing in the three-way valve in the background technology. [0004] The adopted technical scheme that the present invention solves its t...
