Beneficial effect:
1, by regulation valve and spring housing spacer pin on support, when current are increasing, it becomes possible to overcome the tension force of spring
Compression spring, makes regulation valve move at regulation ring minimum-value aperture, the most just changes the channel sized between regulation valve and pedestal,
When arriving at regulation valve maximum gauge at regulation ring minimum-value aperture, spring is compressed to the limit, at this moment, and regulation valve and base
Passage between Zuo is minimum, thus plays the effect limiting flow；By selecting the spring of different rigidity, change spring pressure
It is reduced to the hydraulic pressure required for the limit, the most just changes max water yield.

Detailed description of the invention
As shown in Fig. 1 to Fig. 3, a kind of tap, the water inlet end at tap is mounted with a thrift lock, and described thrift lock is mainly made up of limit base 1, pedestal 2, regulation valve 3, spring 4, positioning seat 5 and limited location snap ring 6；One end margin of described limit base is provided with the spacing bead more than pedestal external diameter of the diameter outwardly, it is provided with support at the limit base endoporus near bead, carriage center is provided with the spacer pin 11 away from bead, and the end at spacer pin 11 is provided with the stopper slot 12 caved inward of more than three；The mode that limit base enters pedestal by spacer pin enters pedestal endoporus, and spacing bead highlights outside pedestal, and limit base is socketed with pedestal or is threaded connection；Being provided with the regulation ring to inner process in the middle part of described pedestal, the endoporus of regulation ring gradually expands to both sides from middle part；Described regulation valve 3 is provided with the spring groove to the direction of limit base depression away from the end face of limit base, regulation valve is provided with the tank to the direction of positioning seat depression towards the end face of limit base, regulation valve center is provided with adjustment hole, described adjustment hole is positioned at the center of tank and spring groove, is provided with the spring retention posts prominent to positioning seat in spring groove side along the edge of adjustment hole；Described spring is tubular spring；Described positioning seat is the cylinder with central through hole, and the locating dowel outer wall away from regulation valve is provided with locating lugs outwardly, and the diameter of locating lugs is less than the diameter of the tank on regulation valve, and the diameter of locating lugs is more than the diameter of spring.
During assembling, by regulation valve pocket on the spacer pin of limit base, again by spring housing on spacer pin, the one end making spring is enclosed within the spring retention posts outer wall of regulation valve, positioning seat 5 is enclosed within spacer pin end again and to the direction pressing spring of support, spring is made to push against regulation valve and be compressed, spring is made to have structural initial pre stress, again limited location snap ring 6 is snapped in and position in the exposed stopper slot out of spacer pin end being positioned at outside support and positioning seat, the thrift lock assembled is filled in towards the mode of water inlet end by limit base the water inlet end of tap.
The maximum magnitude that spring can compress is when the spring retention posts regulated on valve props up positioning seat, cannot recompress.The diameter of spring is more than the external diameter of spring retention posts.
Described positioning seat forms tight fit with spacer pin.Current flow from one end of limit base to the direction of regulation valve, when hydraulic pressure is increasing, regulation valve is pressed into regulation ring by the tension force effect that just can overcome spring, along with hydraulic pressure is increasing, regulation valve more enters regulation ring, when spring retention posts pushes against positioning seat, arrives at the minimum-value aperture of Gao Jiehuan at the maximum outside diameter of regulation valve, at this moment, regulation valve also leaves space water supply stream pass through with regulating interannular.
For the setting of spring structural initial pre stress, in addition to the stopper slot entered by changing limited location snap ring changes, additionally it is possible to by overlapping one or more pads on spacer pin, make these pads regulate between valve and support, thus change the structural initial pre stress of spring.
Described limited location snap ring is the annular with opening, and the two ends of opening outwards turn down formation card article, and the diameter of bore of limited location snap ring is less than the diameter of spacer pin, and when limited location snap ring is pressed into stopper slot, card article is pressed on the locating lugs end face of limit base.During limited location snap ring to be taken off, the card article holding opening two ends is pulled outwardly, and makes the endoporus of limited location snap ring become big, it becomes possible to be taken off from spacer pin by limited location snap ring.
The maximum gauge of regulation valve is less than the minimum-value aperture of the regulation ring of pedestal.
The length of described spacer pin 11 is more than the distance at support to regulation ring minimum-value aperture.
Before using, select elastic different spring according to use, thus change the max water yield of tap.Such as, for washing the tap of dish, select the spring that elasticity indexes coordinates, make max water yield control within 6L per minute, for shower faucet, select the spring that elasticity indexes coordinates, maximum output is made to control within 10L per minute, the tap washed one's hands for washing one's face, the spring selecting elasticity indexes to coordinate, make maximum output control within 4L per minute.So that water yield obtains an equitable breakdown, this big place is big, this little occupying a narrow space, beneficially using water wisely.
Above-described embodiment is intended merely to interpretation purposes of the present utility model; and be not to restriction of the present utility model, those skilled in the art, in essential scope of the present utility model; make a variety of changes or substitute, also should belong to protection category of the present utility model.
