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.
Beneficial effect:
1, spring, regulation valve and positioning seat are sequentially sleeved on spacer pin, by spacing by limited location snap ring after spring-compressed, make bullet
Spring has initial prestressing force, along with the increase of hydraulic pressure overcomes the structural initial pre stress of spring, makes spring compress further, will
Regulation valve gradually advances in the regulation ring of pedestal, until by spring-compressed to the limit, at this moment, at the maximum gauge of regulation valve
At the minimum-value aperture of the regulation ring of motor seat, make the space between regulation valve and pedestal diminish, thus play restriction flow
Effect；By selecting the spring of different rigidity, change the hydraulic pressure required for spring-compressed to the limit, the most just change
Max water yield.

Detailed description of the invention
As shown in Fig. 1 to Fig. 3, a kind of thrift lock, mainly it is made up of limit base 1, pedestal 2, spring 3, regulation valve 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 4 is provided with the tank to the direction of limit base depression away from the end face of limit base, it is provided with the spring groove to the direction depression away from regulation valve regulating the valve end face towards limit base, it is provided with adjustment hole at regulation valve center, described adjustment hole is positioned at the center of tank and spring groove, is provided with the spring retention posts prominent to limit base in spring groove side along the edge of adjustment hole；Described spring is tubular spring；Described positioning seat is provided with the central through hole can being enclosed within spacer pin.
During assembling, by spring housing on the spacer pin of limit base, valve pocket will be regulated at spacer pin end, the one end making spring enters in the space between spring locating slot and spring groove, positioning seat 5 is enclosed within spacer pin end again and to the direction of support pressure regulation valve, make spring be compressed, make spring have structural initial pre stress, then limited location snap ring 6 is snapped in location in the exposed stopper slot out of spacer pin end being positioned at outside support and positioning seat.
The maximum magnitude that spring can compress is when the spring retention posts regulated on valve pushes against support, 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 to the direction of limit base from regulation valve one end, 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 support, 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, outside changing with the stopper slot entered by changing limited location snap ring, additionally it is possible to one or more pads on overlapping on spacer pin, make these pads between spring and support, thus change the structural initial pre stress of spring.
Described positioning seat is cylinder, 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.
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.
When installing and using, by limit base mode outwardly, thrift lock is filled in the water side of pipeline, then in the water side of regulation valve, tap or other water tube component is installed, make the spacing bead of limit base between pipeline, make thrift lock be positioned at the fixed position of pipeline, prevent thrift lock from being washed away by current.
The spring that different choice rigidity according to use is different, to meet the requirement to water yield of the different outlets.
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.
