Abstract

The utility model relates to a water tap with a double passageway ceramic valve core. A movable sheet and a fixed sheet which are made of high strength ceramics are arranged in a casing of a tap. The shape of the cross section of the movable sheet is the same as the shape of the cross section of the fixed sheet. The contact surface of the movable sheet and the fixed sheet is polished, and the movable sheet is provided with two interval grooves. When the movable sheet is driven to rotate by the rotation of a handle, the grooves arranged on the movable sheet are staggered with a water inlet hole and a water outlet hole which are arranged on the fixed sheet to form a water passing channel to cause running water to flow out; when the grooves arranged on the movable sheet are oppositely fitted with the water inlet hole and the water outlet hole which are arranged on the fixed sheet, the running water is closed, and thereby, the functions of the opening and the closing of the water tap and regulation of the size of water yield are realized. The utility model is suitable for being used as a switch device for the running water used in daily life of people and industry and agriculture production, or for other fluids of pipelines with pressure.

Description

Twin channel porcelain spool water tap

The utility model relates to a kind of device, especially water tap of being made up of handle, porcelain spool, housing of energy switch tap water.

Water tap, valve are the daily life articles for use, and present normally used water tap has two kinds, and a kind of is the water tap of making sealing gasket with sheet rubber, and owing to sheet rubber weares and teares easily, wears out, so the working life of this class water tap or valve is not long.Another kind is to adopt the high-strength ceramic sheet as spool, the surface of contact of still and moving plate is worn into minute surface, movement parts in the tap has just had good wear resistance and corrosion resistance like this, therefore this class tap is comparatively durable in use, but this porcelain core valve also exists structural defective, the one, because the tie point of moving plate and rotating shaft is located on the garden circumferential edges of moving plate, make that the impossible Kai Detai of inlet on the ceramics is big, therefore the water-outlet quantity of this class water tap or valve is less, and the 2nd, this class water tap adopts two seals with elastometic washer in rotating shaft, and rubber ring is easily aging after use a period of time, non-refractory, easy to wear, after the wearing and tearing, water can overflow from handle.The 3rd, the throughway valve of this structure also has the differentiation of positive reversal connection, mainly is easily to cause eddy current to cause because also will walk around the side opening on the garden ring that extends on the set screw nut behind the water process porcelain valve block, easily makes mistakes during installation.The water tap of this class ceramic valve core or valve mechanism complexity in a word, water-outlet quantity is little, is subjected to the influence of easily damaged parts in the tap working life and impermanent, makes troubles for people's daily life.

The purpose of this utility model aims to provide a kind of simple in structure, durable in use, easy for installation, water tap or valve that water-outlet quantity is big, the daily life that is convenient for people to.

The technical solution of the utility model is to open the groove at two intervals on the moving plate that adopts in housing, water-in and water-out oral pore on the still is relative with the groove on the moving plate, water-in and water-out directly exchange on moving plate, simultaneously the point of contact of moving plate and rotating shaft are located at that the central position of moving plate realizes.

Compared with prior art, the utility model has following characteristics:

1. owing to increased the discharge area, water-outlet quantity increases.

2. cancelled rubber seal, prolong working life.

3. it is simple and clear to cross water-bound, adapts to the requirement of different regions hydraulic pressure.

4. strong condition is identical during owing to such valve water-in and water-out.So having positive reversal connection, such throughway valve do not distinguish, easy for installation.

Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.

As shown in the figure, model utility includes handle 1, housing 7, in can be made into, housing 7 connects, external, the tap shape, in housing 7, put into silicagel pad 6 earlier, silicagel pad 6 outer rims wrap in the garden circumferential edges of still 5, in the silicagel pad 6 every projection be embedded in the groove below still 5 middle parts, both are combined together, the garden of still 5 in axial direction also has two tongues on week, it just in time with housing 7 on two grooves coincide, still 5 is fixing also fixing with silicagel pad 6 simultaneously like this, still 5 and moving plate 4 are all by high strength china material system, their surface of contact all is polished minute surface, moving plate 4 is identical with the shape of cross section of the surface of contact of still 5, two grooves that shape is identical have been opened in moving plate 4 bottoms, the centre is separated by space bar, having groove in the middle of the top of moving plate 4 cooperates with the tongue of rotating shaft 2, between rotating shaft 2 and the gland nut 3 for movingly, gland nut 3 and housing 7 are for being threaded, tightening gland nut 3 can be with moving plate 4, still 5, silicagel pad 6 tightly forces together with housing 7, gland nut 3 is also polished with contacting of moving plate 4, and on gland nut, be provided with four silicone oil holes 8 and load onto silicone oil in order to long-term lubricated, and on housing 7, have two relative fan grooves, the garden of moving plate 4 has two salient points to place in this groove on week, handle 1 is socketed in the rotating shaft 2, when handle 1 rotates, moving plate 4 can be made 90 ° of degree along this fan groove and rotate, and plays out, close and the effect of the transfer water yield.

Working principle is as follows: when the cross section of moving plate 4 and still 5 matches, water in the running water pipe enters in the groove of moving plate 4 by the water inlet of silicagel pad 6 and still 5 at this moment, because the surface of contact of still 4 and moving plate 5 is polished, so it is water-tight, at this moment, tap is in closed condition, when rotatable handle 1, it will drive rotating shaft 2 and moving plate 4 rotates, at this moment two grooves on the moving plate 4 will with the water inlet on the still 5, osculum is staggered, be that every groove part is understood some and ridden over the water inlet, another part rides on the osculum and forms passage, tap water will flow out through osculum along this two passes, because the connecting groove of rotating shaft 2 with moving plate 4 designed above the space bar in the middle of the moving plate 4, therefore, two grooves of moving plate 4 can be made the high, normal, basic saddle in limit to reduce fluid resistance, when handle 1 rotates the slot cross-section that drives moving plate 4 and rotation and still 5 when coincideing again, just recovered to arrive the closed condition of water tap again.This shows, need only handle with sleeve 1 simply, just can realize the open and close and the transfer water yield size of water tap.

The handle of above water tap, rotating shaft, gland nut, moving plate, still all adopt 95% alumina ceramic materials to make, and housing can adopt plastics or metallic material to make.
