Description of the invention: [Technical Field] The present invention is a control water valve that provides a structural design of a closed water compartment. [Prior Art] At present, various types of water control switches are sold on the market, among which the infrared sensing water valve is the most representative. When people perform silk action, they need to place their hands in an appropriate position, by infrared rays. Induction, so that the water valve can be opened, so that the faucet can perform the action of water supply. However, such a valve still has its shortcomings, because the water supply time of this type is limited, and During the time, people usually can't complete the washing action, so they must perform the sensing action again. In addition, the infrared sensor is not awkward. Wei Lingmin' must put the hand in a specific sensing area so that the infrared light can be sensed. In the aforesaid inconvenience, an existing control water valve is produced. For the existing control water valve, please refer to the sixth and seventh figures, which have an outer sleeve (50), a control valve M (6 〇) and a positioning member (70); the outer sleeve (5) 0), a top end portion is formed with a stepped top groove (5 1 ), and a bottom end of the top groove (5 work) is formed with a constant hole (52) at the bottom end of the outer casing (50) The end portion is formed with a stepped bottom groove (53). The top groove (51) and the bottom groove (53) are in communication with each other through the through hole (52); the control valve group (60), have

When the control water valve is closed, the water in the pipeline will still flow forward, so when the water valve is closed instantaneously, the water hammer phenomenon is generated, and the water is flowing. The kinetic energy is transformed into elastic energy' to produce a series of positive and negative pressure magic skins, which vibrate back and forth in the pipeline until the energy is blocked by the friction, and then the vibration of the main pipe is 1271484: (7 0) % has a valve seat (6 2) fixing holes (7 1 ) of the bottom ends of each other by the control valve group (6 〇) are disposed on the outer sleeve (50) Θ 'in the positioning member (7〇) and adjacent to the fixing holes ( 7丄) There are several water holes (7 2 ) spaced apart from each other at the position. In actual use, the existing control cymbal can be connected to a faucet. When the faucet is out of water, the bottom end of the struts (6 4) can be pushed, and the oblique guide edge (642) at the top end is pushed. The pusher (6 32) of the lever (63) is engaged with each other and pushes the pusher (63), and the top end of the pusher (6 3 2 ) is again with the side of the extension lever (6 1 2) | (6 workers 3) The bottom ends of each other are pushed against each other, so that the closed end portion (6 i丄) is separated from the through hole (5 2 ), and the through hole (5 2 ) is no longer closed, so that water can enter the through hole (5 2 ). In the bottom recess # ( 5 3 ), it flows out to the outside of the outer (4) (5 Q ) through the orifice (6 2 4 ) and the water hole (7 2 ) in order, so that the washing action can be performed. When the washing action is completed, it is only necessary to push the abutting rod (64) again, so that the guiding block (643) enters the guiding groove (623) and abuts against the bottom end of the guiding groove (6 4 3 ). The card-inhibiting action no longer exists, and the top end of the closed end (6 1 1 ) is immediately closed by the pushing of the water pressure to close the through-hole (5 2 ), so the water cannot flow out. 1271484 Movement and harsh noise. SUMMARY OF THE INVENTION In view of the prior art inconvenience described herein, the present invention is directed to a design that controls the water valve to provide a design that can be used to close the water valve. In order to achieve the above object, the technical model used in the present invention is a control water valve, which has a sleeve body, a top seat and a control room group, a sleeve body which has an opening, and a top seat which is disposed on the sleeve. At the top end of the body, the top end of the top seat is formed with a receiving groove 'having a water hole at the bottom end of the receiving groove; the control valve group has a valve seat, a push rod and an abutment; the seat ' is set in the opening of the sleeve a hole is formed in the center of the valve seat, a beveled guide hole is formed on the inner peripheral wall of the through hole, and a guide groove is formed between the oblique guide edges; the push rod is disposed at the through hole of the valve seat a groove is formed at the top end of the push rod, and a beveled guide edge is formed at the top end of the push rod, and a protruding guide block is formed at the peripheral wall of the same end; the seat is formed with a perforation at the bottom end of the seat A plurality of protruding and spaced apart abutting pieces are formed, and the abutting pieces can be engaged with the inclined leading edges of the push rods. The control water valve can be disposed at the water outlet end of the water pipe. When the control valve group can be pushed up from the bottom to the top, the control valve group sequentially closes the flow hole of the cover body and the water hole of the top seat from top to bottom, so the water flow will not be When the control valve group is pushed and moved from the top to the bottom, the flow hole of the cover body and the water hole of the top seat are opened, so that the water flow can flow out from the water outlet end. 1271484 By the above action, when the water outlet is closed, the water system is controlled to use the progressive closing and the second-stage closing mode, so that the positive and negative pressure waves generated when the flow stops can be reduced, thereby avoiding the vibration of the main pipe. Produces harsh noise.
