Embodiment
A kind of throttle valve as shown in Figure 1 and Figure 2, it comprises handle 1, valve body 2 and spool.
As shown in Figure 2, spool comprises valve rod 5, regulates lamellar body 8 and fixing lamellar body 9.Regulate lamellar body 8 and fixedly lamellar body 9 be ceramic plate.Valve rod 5 rotating being inserted in the valve seat 6,6 of valve rod 5 and valve seats are provided with seal ring 12, seal ring 13 and seal ring 14.Valve body 2 is a three-port structure, wherein flatly for import, flatly for outlet, another mouthful and valve seat 6 by being threaded, 2 of valve seat 6 and valve bodies are provided with seal ring 7 and seal ring 10.Valve seat 6 centers are porose, and the sidewall that valve seat 6 enters the end in the valve body 2 is provided with and portals 11, portal 11 to be connected with the outlet of valve body 2.Regulate lamellar body 8 and fixedly lamellar body 9 be arranged on valve seat 6 and be in the end in the valve body 2, valve rod 5 extend in the valve seat 6 from the other end of valve seat 6, valve rod 5 can rotate in valve seat 6.Regulate lamellar body 8 for having the wafer body of gap, regulate lamellar body 8 and be provided with two grooves, valve rod 5 is provided with two projectioies, and two projectioies of valve rod 5 just in time are stuck in two grooves of regulating on the lamellar body 8, makes that regulating lamellar body 8 can rotate under the drive of valve rod 5.Fixedly lamellar body 9 is circular, and the middle part is provided with small opening.Fixedly the circumferential surface of lamellar body 9 is provided with two projectioies, is provided with two grooves in the inner peripheral surface of valve seat 6, and fixedly two of lamellar body 9 high spots are in two grooves of valve seat 6.Thereby make adjusting lamellar body 8 follow valve rod 5 when valve seat rotates, fixedly lamellar body 9 relative valve seats 6 are static relatively.Fixedly the small opening on the lamellar body 9 communicates with water intake on the valve body 2.Be with return spring 4 on the valve rod 5, valve rod 5 is in valve seat 6 outer ends and is provided with handle 1 outward, and handle 1 fixes by screw 3 and valve rod 5.Return spring 4 one ends are fixed on the valve seat 6, and the other end is fixed on the handle 1.When handle with sleeve 1, handle 1 can drive valve rod 5 and rotate, and when release handle 1, return spring 4 drives handle 1 and valve rod 5 returns.Fixedly the small opening of lamellar body 9, regulate portalling on gap on the lamellar body 8 and the valve seat 6 and 11 be connected, form the communication passage that is communicated with valve body 2 imports and outlet.Regulate the gap of lamellar body 8 and fixedly the overlapping part of lamellar body 9 be the smallest cross-sectional place of aforementioned communication passage.
The smallest cross-sectional of the communication passage the when smallest cross-sectional of communication passage is in free state greater than handle 1 when application of force rotatable handle 1.The original state of this throttle valve (promptly when handle 1 be in free state) is: sub-fraction is arranged the gap of regulating lamellar body 8 and fixedly the small opening of lamellar body 9 is overlapping, when application of force handle with sleeve 1, handle 1 can drive valve rod 5 and regulate lamellar body 8 and rotate, make the gap of regulating lamellar body 8 and fixedly the overlapping part of the small opening of lamellar body 9 become gradually greatly, thereby adjust the size of the water yield.
The spool of this throttle valve also can adopt other structure, as long as spool is provided with the communication passage that smallest cross-sectional can change by the rotation of handle.
A kind of slow pressure energy-saving tap as shown in Figure 3 comprises throttle valve 15, has valve 16 and water pipe 17 by function, the throttle valve that throttle valve 15 adopts shown in Fig. 1-2, and throttle valve 15 and valve 16 all are installed on the water pipe 17.
This slow energy-saving tap using method of pressing: open valve 16, just having less current flows out, can satisfy general operational requirement, when the big current of needs, rotate the handle 1 of throttle valve 15 by hand, handle 1 drives valve rod 5 and rotates, valve rod 5 drives regulates lamellar body 8 rotations, thereby make and regulate the overlapping area of lamellar body 8 and the small opening of fixing lamellar body 9 and become big, thereby make the smallest cross-sectional of communication passage become big, make that the current quantitative change is big.Release handle 1, return spring 4 drive handle 1, valve rod 5 and regulate lamellar body 8 and reset.Thereby recover than small flow.
