Abstract

The utility model discloses a tap valve spool, wherein a sealing pad, an upper and lower ceramic plates, a spool slide base and a spool rotator are installed one by one in the space formed by the spool base and the spool shell; the valve body projects out of the spool shell; a leaf spring is socketed on the valve handle; a retaining groove is formed on the spool rotator, at a position corresponding to the leaf spring; the valve handle can be switched to different stages to regulate the volume of water discharge, both time-saving and water-saving; counter bores are opened respectively below the water inlet and water outlet of the lower ceramic plate; a sealing ring is respectively provided between the lower ceramic plate and the spool base and between the spool base and the water source for connection purposes to realize three-dimensional sealing effect.

Description

A kind of faucet valve core

The utility model relates to a kind of water tap, refers in particular to a kind of faucet valve core.

As shown in Figure 1, be the faucet valve core of commonly using, comprise spool base 1 ', spool housing 2 ', following ceramic plate 3 ', go up ceramic plate 4 ', spool slide 5 ', spool solid of rotation 6 ', valve handle 7 ', valve handle axle 8 ' and sealing gasket 9 ', valve handle 7 ' is articulated on the spool solid of rotation 6 ' by valve handle axle 8 ', and the interior outside of valve base 1 ' has the groove 11 ' that is provided with ccontaining sealing gasket 9 ' respectively; Spool slide 5 ' is fixed together with last ceramic plate 4 '; Sealing gasket 9 ', upper and lower ceramic plate 4 ', 3 ', spool slide 5 ', spool solid of rotation 6 ' are assemblied in the space of spool base 1 ' and spool housing 2 ' composition successively, the other end of valve handle 7 ' is stretched and is placed 2 outer cooperations with handle of spool housing to fix, control valve handle 7 ' by pulling handle and descend ceramic plate 3 ' to move relatively, realize controlling the function of water outlet with this to drive ceramic plate 4 '.

But in the above-mentioned structure, people rely on the tap of fetching boiling water to observe the size of water flow, adjust the required water amount with this, and are so promptly time-consuming, water wasting again; In addition, sealing gasket is to place between valve base and following ceramic plate and valve base and the water source, and it plays the effect of a plane sealing, if easily produce water leakage phenomenon under the situation of high hydraulic pressure, so sealing effect is not good.

Main purpose of the present utility model provides a kind of user of order has the control of gear sensation when pulling handle faucet valve core.

Secondary objective of the present utility model provides a kind of faucet valve core that improves sealing effect.

For achieving the above object, solution of the present utility model is: a kind of faucet valve core, mainly comprise the spool base, the spool housing, ceramic plate up and down, the spool slide, the spool solid of rotation, valve handle, valve handle axle and sealing gasket, valve handle is articulated on the spool solid of rotation by the valve handle axle, sealing gasket, ceramic plate up and down, the spool slide, the spool solid of rotation is assemblied in the space of spool base and spool housing composition successively, valve handle is stretched and is placed valve core shell external, wherein be arranged with spring sheet, and on the spool solid of rotation, form the gear groove with the corresponding position of spring sheet at the valve handle place.Described a kind of faucet valve core, wherein spring sheet comprises one The spring last slice of type and one Sheet under the spring of type, spring sheet is fixed on the valve handle by a valve handle overcoat.

Described a kind of faucet valve core wherein offers counterbore at following ceramic plate respectively below the water hole; Sealing gasket is by forming corresponding to the seal ring of counterbore size; On the spool base into and out of the size in water hole also corresponding seal ring size and be provided with, be connected combination by seal ring respectively between following ceramic plate and spool base and spool base and the water source.

After adopting such scheme, because the setting of gear groove snaps in the gear groove by shell fragment, make its control that gear sensation is arranged, the user then pulls different gears to adjust the water yield according to the individual is required when pulling handle, so promptly save time, again water-saving; Because between following ceramic plate and valve base and valve base and the water source is by seal ring simultaneously with three's long splice altogether, the integral sealing area is increased, and realize three-dimensional seal, no matter promptly radially or axially all possessing seal action, if hydraulic pressure is high more, its sealing effect is good more.

Below in conjunction with drawings and Examples the utility model is further described.

Fig. 1 is a three-dimensional exploded view of commonly using product;

Fig. 2 is a three-dimensional exploded view of the present utility model;

Fig. 3 is a three-dimensional assembled sectional view of the present utility model.

Shown in Fig. 2,3, it also mainly comprises spool base 1, spool housing 2, following ceramic plate 3, goes up ceramic plate 4, spool slide 5, spool solid of rotation 6, valve handle 7, valve handle axle 8 and sealing gasket 9, and valve handle 7 is articulated on the spool solid of rotation 6 by valve handle axle 8; One end 71 of valve handle 7 is stretched in the groove 51 that places spool slide 5; Spool slide 5 is fixed together with last ceramic plate 4; Sealing gasket 9, upper and lower

ceramic plate

4,3, spool slide 5, spool solid of rotation 6 are assemblied in the space of spool base 1 and spool housing 2 compositions successively, the other end 72 of valve handle 7 is stretched and is placed 2 outer cooperations with handle of spool housing to fix, key of the present utility model is: be arranged with two spring sheet A, B at valve handle 7 places, upper spring sheet A is one Type; Lower spring sheet B is one Type, two spring sheet A, B are fixed on the valve handle 7 by valve handle cover C; And on spool solid of rotation 6, form gear groove 61 with two spring sheet A, the corresponding position of B, lower spring sheet B is buckled in the gear groove 61, the dealer can establish the gear groove of the different numbers of tool according to needs, because the setting of gear, then the sectional area of valve handle 7 reduces relatively, cooperates valve handle cover C to fix with the cooperation that is adapted to the standard piece handle, when the user when pulling valve handle 7, drive two spring sheet A, B and snap in the different gear grooves 61 water-saving that saves time according to need with effective control water-outlet quantity.

In addition, below the water inlet 31 of descending ceramic plate 3, osculum 32, offer counterbore 311,321 respectively; Sealing gasket 9 is made up of the

seal ring

91,92 corresponding to counterbore 311,321 sizes; The size of the water inlet 11 on the spool base 1, the also

corresponding seal ring

91,92 of the size of osculum 12 and being provided with, be connected combination by

seal ring

91,92 respectively between spool base 1 and following ceramic plate 3 and spool base 1 and the water source,

seal ring

91,92 will descend ceramic plate 3 and valve base 1 and valve base 1 and water source three's long splice altogether simultaneously, the integral sealing area of spool is increased, axially realize seal action simultaneously radially reaching, if hydraulic pressure is high more, then current are big more to the power that seal

ring

91,92 radially outwards applies, and then its sealing effect is good more.
