Abstract
The utility model relates to a spool of a water-saving joint. The spool is installed in the water-saving joint for use, and the water-saving joint mainly comprises a body, the spool, a limiting platform, a conical platform, a positioning seat, a spring and a screw. The spool comprises a valve head, a valve stem, a pressure relief hole and a limiter, wherein more than two pressure relief holes are formed in the valve head. By arranging the valve head to be of the shape of an olive with a large middle part and two small ends, the wall surface of the valve head towards a water inlet end is enabled to be an inclined surface which is inclined towards the middle part of the valve head from the valve stem and the resistance to water can be effectively reduced. Since the pressure relief holes are formed on the edge of the middle part of the valve head and the wall surfaces of the pressure relief holes are arc-shaped, the resistance to the water is further reduced.
Description
Technical field
The utility model relates to a kind of spool of the water saving joint connecting for running water pipe, belongs to the optimisation technique of water pipe adapter.
Background technique
A kind of water pipe adapter is disclosed in the patent document that is 201020694120.3 in the patent No., advantage be can from feed-water end by adjusting screw the position on throttle valve valve rod, the prestressing force of Regulation spring, thereby setting max water yield, in water utilizing process, water pipe adapter can regulate automatically according to the variation of hydraulic pressure, and water-outlet quantity is remained in the maximum magnitude of setting.Deficiency is that the valve head of throttle valve is shaped as taper platform, is the plane vertical with body axle center towards the end face of feed-water end, larger to the resistance of current, easily forms turbulent flow at water inlet end face.
Therefore, need to find a kind of spool that can effectively reduce the resistance of valve head to current formation.
Summary of the invention
The purpose of this utility model is to provide a kind of spool that can effectively reduce the resistance of valve head to current formation.
The technical solution of the utility model is: a kind of spool of the joint of economizing on water, spool is arranged in water saving joint and uses, water saving joint is mainly made up of body 1, spool 2, limiting platform 3, taper platform 4, positioning seat 5, spring 6, screw 7, described spool 2 comprises again valve head 21, valve rod 22, relief hole 23, snubber 24, has plural relief hole 23 on described valve head 21; Described limiting platform 3 is for being provided with the annular platform of through hole to the middle part of inner process in the middle part of inner body wall, positioning seat screws in body from the inlet end of body, and the maximum diameter of positioning seat is greater than the aperture of limiting platform middle through-hole; Be provided with in one end of limiting platform 3 water outlets from feed-water end to waterexit end and to the taper platform 4 of the central axis direction projection of body, taper platform middle part is provided with cone shape hole; Described valve rod 22 one end are connected with valve head 21, and the other end is provided with screw 221; The direction of one end that described valve rod 22 is provided with screw 221 from water outlet to water intake is through the center hole of positioning seat 5, screw 7 is tightened in screw 221, spring is fixed between nut and support, described valve head is Olive Shape small in ends broad in the middle, described relief hole is positioned at the edge of valve head, through valve head middle part maximum diameter, arrive the valve head wall towards waterexit end from the valve head wall towards feed-water end; Valve head can enter cone shape hole towards the part of waterexit end under current promote, and cone shape hole is blocked, and at this moment, current can only flow out by relief hole.
The maximum diameter of described valve head is less than the diameter of bore of limiting platform, and current can be flow through from the space between valve head and limiting platform.
The wall of described relief hole is circular arc.
beneficial effect:
1,, by valve head being arranged to the little Olive Shape in two broad in the middle, making valve head is the inclined-plane that middle part tilts from valve rod to valve head towards the wall of feed-water end, can effectively reduce the resistance to water.
2, relief hole is arranged on to edge, valve head middle part, the wall of relief hole is circular arc, to reduce the resistance to water.
Accompanying drawing explanation
Fig. 1 is the schematic diagram that the utility model is arranged on application in water saving joint;
Fig. 2 is perspective view of the present utility model.
Embodiment
As depicted in figs. 1 and 2, a kind of spool of the joint of economizing on water, spool is arranged in water saving joint and uses, and water saving joint is mainly made up of body 1, spool 2, limiting platform 3, taper platform 4, positioning seat 5, spring 6, screw 7.
Described spool 2 comprises again valve head 21, valve rod 22, relief hole 23, snubber 24, has plural relief hole 23 on described valve head 21.
Described limiting platform 3 is for being provided with the annular platform of through hole to the middle part of inner process in the middle part of inner body wall, positioning seat screws in body from the inlet end of body, and the maximum diameter of positioning seat is greater than the aperture of limiting platform middle through-hole.Inner body wall is all provided with internal thread except limiting platform part, and the outer wall of positioning seat is provided with corresponding outside thread, and positioning seat screws in body fixing.
Be provided with in one end of limiting platform 3 water outlets from feed-water end to waterexit end and to the taper platform 4 of the central axis direction projection of body, taper platform middle part is provided with cone shape hole, water supply stream passes through.
Described valve rod 22 one end are connected with valve head 21, and the other end is provided with screw 221; The direction of one end that described valve rod 22 is provided with screw 221 from water outlet to water intake is through the center hole of positioning seat 5, and screw 7 is tightened in screw 221, and spring is fixed between nut and support.The diameter of snubber is greater than positioning seat center hole aperture, makes to keep at a distance between valve head and positioning seat, and the hole that water can be smoothly through on positioning seat flows to valve head one end.
Described valve head is Olive Shape small in ends broad in the middle.Water flows to waterexit end from the feed-water end of body, while flowing through the feed-water end wall of valve head, due to wall be from valve rod to valve head middle part edge tilt, water be take advantage of a situation mobile, less to the resistance of water.
Described relief hole is positioned at the edge of valve head, through valve head middle part maximum diameter, arrives the valve head wall towards waterexit end from the valve head wall towards feed-water end; Valve head can enter the cone shape hole of taper platform towards the part of waterexit end under current promote, and cone shape hole is blocked, and at this moment, current can only flow out by relief hole.
The maximum diameter of described valve head is less than the diameter of bore of limiting platform, and current can be flow through from the space between valve head and limiting platform.
The wall of described relief hole is circular arc.To reduce the resistance to current.
Above-described embodiment is only for 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.
