Detailed description of the invention
As shown in Fig. 1 to Fig. 4, a kind of thrift lock, mainly by housing 1, regulation valve 2, spring 3, screw 4 and shim pack
Becoming, housing is the cylinder of hollow, and the water inlet end endoporus at housing is provided with the support 11 of water hole, and the heart sets in the bracket
The locating dowel 12 of oriented water side projection, locating dowel is provided with central through hole, is provided with female thread in the central through hole of locating dowel 12；
Being provided with the boss 13 to inner process between support and the water side of housing, the middle aperture of boss 13 is minimum, boss 13
Endoporus gradually expands to two ends from middle part narrowest position；Described regulation valve is the cone with central through hole, logical around center
Hole is provided with the locating slot to vertex of a cone direction depression at the cone end of regulation valve.
The aperture of the central through hole of regulation valve is less than the external diameter of locating dowel, more than the diameter of bore of locating dowel；Described locating slot
Minimum-value aperture more than the external diameter of locating dowel；Regulation valve was enclosed within locating dowel towards the mode of water inlet end by the cone end, made locating dowel court
On the diapire of the locating slot being against regulation valve to the edge of the end face of water side；The screw rod of described screw is provided with the root from screw rod
The positioning sleeve that portion extends to the end of screw rod, is set to the screw rod outer wall between the end of screw rod in location and arranges the center with locating dowel
The external screw thread that female thread in through hole matches；By pad and spring housing on the screw rod of screw, the screw rod of screw press nut towards
The mode of water side inserts the central through hole of the central through hole arrival locating dowel of regulation valve, driving screws, makes the end of screw rod enter
The central through hole of locating dowel, nut to the direction holddown spring of water inlet end and regulation valve, makes spring have initial pre-from water side
Stress.By just can change screw rod position in locating dowel from water side driving screws, thus the most just change the pine of spring
Tight degree, thus change the size of spring structural initial pre stress.
Current enter in housing from water inlet end and flow to the direction of water side, when hydraulic pressure is sufficiently large, promote regulation valve to overcome bullet
The prestressing force of spring moves to the direction of water side, makes the gap between regulation valve and boss more and more less, when spring is compressed to pole
In limited time, the position of regulation valve maximum outside diameter moves to the place that boss aperture is minimum.
The locating slot of described regulation valve is the cone end circular cone table towards water inlet end or cylinder.
Described spring is tubular spring, and the external diameter of spring is less than the diameter at the cone end of regulation valve, again smaller than the external diameter of pad,
Spring is made to be positioned on the screw rod between regulation valve and pad.
The spiro rod length that location is set between the end of screw rod is not less than the length of the central through hole of locating dowel.
Spring and regulation valve are pressed on successively on support by this utility model by screw.As shown in Fig. 5 to Fig. 6, in reality
Use in, external screw thread is set outside housing, this utility model is screwable into water pipe from the water side of water pipe, then in this practicality
Tap or shower are installed in novel water side, and when hydraulic pressure is excessive, water jet propulsion regulation valve moves to water side, until adjusting
Arrive at boss minimum endoporus at the maximum outside diameter of joint valve, make gap between the two diminish, thus play and control max water yield
Effect.
When regulating the prestressing force of spring, by screw is screwed to the direction of water inlet end or water side, it becomes possible to more compress
Spring or pull-off spring, thus change the prestressing force of spring, the most just change the size promoting the hydraulic pressure required for regulation valve.
The nut of screw is provided with in-line or criss-cross groove, rises with a word used in everyday or cross rises and mates, regulation
Time, it is only necessary to corresponding use one word rises or cross plays the groove being just inserted on nut and is adjusted.
Above-described embodiment is intended merely to interpretation purposes of the present utility model, and is not to restriction of the present utility model, this skill
The those of ordinary skill in art field, in essential scope of the present utility model, makes a variety of changes or substitutes, and also should belong to this reality
With novel protection category.
