Description
Technical field
The present invention relates to a kind of optimisation technique that can be adjusted the thrift lock of max water yield, belong to thrift lock.
Background technology
Connection between water supply pipe, the connection between water pipe and tap is all realized by joint.To building
Supply water, typically there is a two ways, it is a kind of be using booster pump from bottom to top send water mode, one kind is to dispose water tank in roof,
The mode conveyed from top to bottom using water-head.Either any to send water mode, different floor hydraulic pressure also can be different, can lead
Cause different floor water yields different.Therefore, now with some there is the water pipe head of balanced-out water to design, it is intended to make different buildings
The water yield of layer tends to identical.
Particularly domestic consumer, because each leading purposes is different, the requirement to water yield is also different, the wash vegetables in such as kitchen
Washing one's face for tap and toilet and sprays first-class at tap, and due to the difference of purposes, the requirement to water yield is also different, for example, wash
The water yield of face tap be maintained at 4 liters/min it is just much of that, and spray the water yield requirement of head more than 8 liters/min, therefore, use
Family is also required to that each leading maximum output is adjusted.
It is, thus, sought for a kind of can adjust the water saving method of max water yield.
The content of the invention
The purpose of the present invention is:Offer is a kind of can to adjust the thrift lock of max water yield.
The technical scheme is that：A kind of thrift lock, is mainly made up of, shell housing 1, spring 2, regulating valve 3 and screw 4
Body is hollow cylinder, sets support 11 in the water side endoporus of housing, the heart is provided with and determined to water inlet end is raised in the bracket
Position post 12, locating dowel is provided with the interior spiral shell for being provided with and matching with the external screw thread of screw in central through hole, the central through hole of locating dowel 12
Line；The boss 13 to inner process is provided between support and the water inlet end of housing, the middle aperture of boss 13 is minimum, boss 13
Endoporus gradually expands from middle part narrowest position to two ends；Support is provided with multiple water holes；Described regulating valve is with center
The cone of through hole, cone bottom is towards water inlet end, and the screw rod of screw is in the way of nut is towards water inlet end from the cone bottom of regulating valve
Into central through hole, then by spring housing in screw rod end, then screw rod end is directed to the center of locating dowel from the direction of water inlet end
Through hole, driving screws make the end of screw rod enter the central through hole of locating dowel, by spring compression in support towards the one of water inlet end
Side, makes spring have initial prestressing force；Current enter the direction flowing in housing to water side from water inlet end, when hydraulic pressure is enough
When big, promote regulating valve to overcome the prestressing force of spring to be moved to the direction of water side, get over the gap between regulating valve and boss
Come smaller, when spring is compressed to the limit, the position of regulating valve maximum outside diameter is moved to the minimum place in boss aperture.
The cone bottom of described regulating valve is around counterbore of its central through hole provided with the nut for coordinating screw.
Described spring is turriform spring, and bottom of towe is withstood on support.
The length of described locating dowel is less than support and the distance at boss minimum-value aperture.
Screw rod outer wall between nut and screwed screw rod covers or outwardly protruding stop bit projection provided with stop bit.
Beneficial effect：
1st, be provided with support in the water side of housing, the heart is provided with locating dowel in the bracket, screw by regulating valve and spring successively
Be pressed on side of the support towards water inlet end, by change position of the screw in locating dowel can just change spring it is pre- should
Power.

Embodiment
As shown in Fig. 1 to Fig. 4, a kind of thrift lock is mainly made up of, housing is housing 1, spring 2, regulating valve 3 and screw 4
Hollow cylinder, sets support 11, the heart is provided with the locating dowel raised to water inlet end in the bracket in the water side endoporus of housing
12, locating dowel is provided with the internal thread for being provided with and matching with the external screw thread of screw in central through hole, the central through hole of locating dowel 12；
The boss 13 to inner process is provided between support and the water inlet end of housing, the middle aperture of boss 13 is minimum, the endoporus of boss 13
Gradually expand from middle part narrowest position to two ends；Support is provided with multiple water holes.
During assembling, the screw rod of screw enters central through hole in the way of nut is towards water inlet end from the cone bottom of regulating valve,
Again by spring housing in screw rod end, then screw rod end is directed to the central through hole of locating dowel, driving screws from the direction of water inlet end
The end of screw rod is entered the central through hole of locating dowel, towards the side of water inlet end there is spring in support spring compression
Initial prestressing force.Because the screw rod end of screw is screwable into the central through hole of locating dowel, locating dowel is to screw, spring and tune
Section valve plays a part of support positioning.
As shown in figure 5, when hydraulic pressure is smaller, it is impossible to promote regulating valve to move, current enter in housing to going out from water inlet end
The direction flowing of water end (W.E.), when hydraulic pressure is sufficiently large, promotes regulating valve to overcome the prestressing force of spring to be moved to the direction of water side, makes
Gap between regulating valve and boss is less and less, as shown in fig. 6, when spring is compressed to the limit, regulating valve maximum outside diameter
Position be moved to the minimum place in boss aperture.
At the cone bottom of regulating valve, the counterbore for the nut for coordinating screw is set around its central through hole.
Described spring is turriform spring, and bottom of towe is withstood on support.
The diameter of spring towards water inlet end is less than the diameter of the vertex of a cone of regulating valve.Enable spring from water side to water inlet end
Direction push against regulating valve.
The length of described locating dowel is less than support and the distance at boss minimum-value aperture.
Screw rod outer wall between nut and screwed screw rod covers or outwardly protruding stop bit projection provided with stop bit, prevents
The only entrance locating dowel of screw rod excessively.
Regulating valve and spring are pressed on support by the present invention successively by screw.Actual in use, outside housing
External screw thread is set, the present invention is screwable into water pipe from the water side of water pipe, then install in the water side of the present invention tap or
Shower, when hydraulic pressure is excessive, water jet propulsion regulating valve is moved to water side, until reaching boss at the maximum outside diameter of regulating valve
At minimum endoporus, gap between the two is set to diminish, so as to play a part of controlling max water yield.
When adjusting the prestressing force of spring, by the way that the direction of screw to water side or water inlet end is screwed, it becomes possible to more
Holddown spring or pull-off spring, so as to change the prestressing force of spring, also just change the hydraulic pressure promoted required for regulating valve.
The nut of screw is provided with in-line or criss-cross groove, is risen with a word used in everyday or cross rises and matched,
During regulation, it is only necessary to which the corresponding groove being just inserted on nut that risen using a word or cross is adjusted.
Above-described embodiment is intended merely to the purposes of the interpretation present invention, and is not limitation of the present invention, this technology
The those of ordinary skill in field, in the essential scope of the present invention, makes a variety of changes or substitutes, and should also belong to the guarantor of the present invention
Protect category.
