the parallel water outlet valve in the embodiment of the application is provided with a plurality of water outlets, a functional cavity corresponding to the water outlets, a plugging component and a valve rod, so that the water outlets can be opened and closed respectively in parallel, and the key control of the water outlets is realized. On the other hand, because the water outlet is realized by opening and closing the pressure relief hole, the water pressure of the water inlet channel does not directly act on the valve rod, and the opening and closing of the water outlet are more labor-saving.

Pressing the key base 41 again, the pressing surface 411 of the key base 41 presses against the inner inclined surface 424 of the rotating member, so that the rotating member 42 moves downward again and rotates a certain angle; when the key base 41 is released, the rotary member 42 moves upward under the action of the restoring force of the pressing spring 43 until the outer inclined surface 426 abuts against the guide surface 117 of the valve housing 11, and then the rotary member 42 rotates a certain angle again until the second protrusion 425 enters the rotation-stopping groove 114 and continues to rise, and stops in the rotation-stopping groove 114, at this time, the rotary member 42 returns to the higher second position shown in fig. 18,

referring to fig. 19 and 20, when the rotary member 42 is in the first position as shown in fig. 19, the rod body 32 of the valve rod 3 is in sealing engagement with the first sealing ring 22, and the pressure relief hole 213 is closed. At this time, since the water passing channel 172 communicates the water inlet 111 and the water passing hole 141, and a water passing gap is formed between the valve rod 3 and the water passing hole 141, the water pressure in the water pressure chamber 175 is equal to the water pressure of the water inlet; on the other hand, the water inlet channel 173 communicates with the water inlet 111, so that the water pressure in the water inlet channel 173 is equal to the water pressure of the water inlet; with respect to the plugging assembly 2, the pressure applied to the upper surface thereof is equal to the water pressure of the water inlet multiplied by the upper surface area thereof, and the pressure applied to the lower surface thereof is equal to the water pressure of the water inlet multiplied by the junction area between the lower surface thereof and the water inlet channel 173; therefore, the pressure on the upper surface is greater than the pressure on the lower surface, the diaphragm 24 abuts against the water surface 122, the water inlet channel 173 cannot be communicated with the water outlet channel 123, and the water outlet 124 is free of water. When the rotary member 42 moves from the first position shown in fig. 19 to the second position shown in fig. 20, the stem 32 of the valve stem 3 slides up, a space is left between the constriction 33 and the first seal ring 22, and the relief hole 213 is opened. At this time, because the water pressure chamber 175 is depressurized and the water pressure in the water inlet channel 173 still exists, the plugging member 2 moves upward, the membrane 24 leaves the water passing surface 122, the water inlet channel 173 is connected to the water outlet channel 123, the water flows out of the water outlet 124, then the boss 34 of the valve stem 3 abuts against the bottom surface of the supporting frame 21, and drives the whole plugging member 2 to move upward until the second position shown in fig. 20.

In the parallel outlet valve 10 in the embodiment of the present application, since the plurality of water outlets 124, the functional cavity 171 corresponding to the water outlets 124, the plugging component 2, and the valve rod 3 are provided, the water outlets 124 can be opened and closed respectively in parallel, and the button control of the plurality of water outlets 124 is realized. On the other hand, water outlet is realized by opening and closing the pressure relief hole 213, so that the water pressure of the water inlet channel does not directly act on the valve rod 3, and the opening and closing of the water outlet are more labor-saving; when the water outlet 124 is closed, the pressure relief hole 213 does not allow water, and the valve rod 3 is hardly affected by water pressure, so that the water outlet is more labor-saving. Because the valve rod hole 153 is opened at the bottom of the oil storage groove 152, when the valve rod 3 slides in the valve rod hole 153, the lubricating oil is automatically brought into the corresponding sealing ring, so that the service life of the sealing ring is longer. By providing the pre-tightening spring 23, even if the water pressure is low in the closed state of the pressure release hole 213, the diaphragm 24 can be reliably pressed against the water surface 122, and water leakage can be avoided. The part of the bowl bottom 243 of the membrane 24, which is not inserted into the groove, is opposite to the water inlet channel 173, so that when the membrane 24 blocks the water passing surface 122, the water pressure of the water inlet channel 173 acts on the membrane 24, and the whole blocking assembly 2 is ensured to be reliably kept away from the water passing surface 122 under the action of the water pressure after pressure relief. The valve rod 3 penetrates through the water through hole 141, so that the area of the water through hole 141, which is smaller and required by a pilot valve (a technical means for maintaining pressure and releasing pressure of a water pressure cavity to enable a main water channel to be switched on and off), is easier to realize. Generally, in order for the pilot valve to be effective, the area of the water through hole 141 must be small enough, and the small water through hole easily causes solid impurities in the water to block the water through hole, so that the whole valve fails. In the embodiment of this application, the area of crossing the water clearance between valve rod 3 and the water hole 141 decides the water area, consequently, obtains less water area of crossing more easily, and valve rod 3 is at the slip in-process, takes away the impurity in the water clearance from the water hole 141 easily, ensures that the life-span of valve can not reduce because of crossing the jam of water hole 141. The boss 34 is pressed against the support frame 21 upwards, so that the support frame 21 moves upwards along with the valve rod 3, the diaphragm 24 can be ensured to be far away from the water passing surface 122, and the communication between the water inlet channel 173 and the water outlet channel 123 is more reliable. The pressing component 4 realizes the position switching of the valve rod 3 through a ball pen structure, and the movement of the valve rod 3 can be more reliable.
