Abstract

The utility model relates to a water inlet valve with a ceramic valve core for a closet seat, which relates to the water inlet valve of a lower water tank of the closet seat. The utility model is characterized in that a rotating shaft of a moving valve core in a ceramic valve body is connected with a start rod, the other end of the start rod is inserted in a long groove of the upper end of an inner buoy, a sealing ring is arranged the ceramic valve body and a nut, and the rotating shaft is connected with the moving valve core by the sealing ring. The utility model adopts the combination of the inner buoy and an outer buoy and uses the floating force of water and the balance weight of the inner buoy to close and open the ceramic valve core in order to realize the water inlet of the water inlet valve, make the opening process or the closing process of the whole water inlet valve rapid and stable, and accurately control a water inlet amount. The whole valve body adopts the design theory of the seal of the sealing ring to make water separated from the shaft and reduce the defect that start resistance is enhanced caused by seal to the shaft. The utility model has the advantage of simple structure. The utility model keeps the long-term and effective use of the shaft.

Description

Water closet ceramic cartridge water intaking valve

Technical field:

The utility model relates to the water intaking valve of toilet seat low level cistern.

Background technology:

At present, it goes up the water intaking valve that uses in the low cistern for closet bowl on the market taps part and all adopts elastomeric material to make, and therefore, existing easily aging distortion, application life weak point and a series of defectives such as member spoilage height.Thereby caused a large amount of wastes of water resource and intake many defect such as malfunctioning.

Summary of the invention:

The purpose of this utility model is to overcome above deficiency and provides a kind of upward taps to adopt the water intaking valve of ceramic cartridge and the separation of water axle.

The utility model is achieved by the following technical solution: this water intaking valve, comprise that there are a ceramic valve body, outer floating drum, interior floating drum in body, upper hose top, its major technique feature is that the rotating shaft of the movable valve plug in the ceramic valve body connects starting handle, the elongated slot of floating drum upper end in the starting handle other end inserts; Also be provided with a joint ring between ceramic valve body and the nut, rotating shaft links to each other with movable valve plug by joint ring; The flowing water breach of described movable valve plug, fixed valve plug is the plurality of sector face; The movable valve plug in the described valve body and the sealing surface fineness of fixed valve plug are 3 grades (Ra0.02～0.04), and under the hydraulic pressure of 6kg/cm, frictional resistance is between 30～60g; Monolateral gap between described movable valve plug and the valve body is 0.8mm～1mm; Described valve body lower portion has a delivery port, makes water pass through last water support and flows into water tank; One water supplement port is arranged on the described valve body, and direction upwards; There are 5 guiding ribs in the floating drum outside in described, and interior floating drum is provided with a counterweight, and weight is between 60g～120g; The position of described valve body must be higher than outer floating drum upper end-face edge 2cm.

The utility model adopts inside and outside floating drum in conjunction with utilizing the counterweight of buoyancy of water and interior floating drum to close and open ceramic cartridge, thereby realizes the water inlet of water intaking valve, also make whole water intaking valve the open and close process fast, steadily, and control inflow exactly.Because whole valve body adopts the design principle of seal ring seal, water is separated with axle, stopped rotating shaft for a long time because of immersing the corrosion that causes in the water, reduced the shortcoming of the starting reactance increase that causes owing to sealing to axle, can make full use of buoyancy of water and impel closing of movable valve plug, make it sensitive more; And permanently effective use simple in structure, as also to have kept axle; Eliminated the phenomenon that open fire occurs simultaneously.Spool water inlet of this water intaking valve and closed adopt the sector design, thereby make the inflow in the unit interval reach maximum value.The fineness of valve core sealed cover requires 3 grades, under the hydraulic pressure of 6kg/cm, hermetic resistance is controlled between 30g～60g.

Fig. 3 is the structural representation of movable valve plug;

Fig. 4 is that the B-B of Fig. 3 is to structural representation;

The specific embodiment;

As shown in Figure 1 and Figure 2, as Fig. 2, movable valve plug 1 is contained in the inside of valve body 10, and fixed valve plug 2 is contained in a side of movable valve plug by big flat washer 3, withstood by joint ring 5; Fixing by nut 11.There are a little plain cushion 4 outer ends that O shape circle 6 and sealing nut 7 are housed between joint ring and the fixed valve plug, rotating shaft 8 connects starting handle 12, rotating shaft is connected with spool by joint ring 5, thereby the water axle is separated, seal more reliably, overcome the shortcoming that starting power that the sealing to axle causes increases, make the switching of spool sensitive more, one water supplement port 31 is arranged at valve body 10 tops, and the lower end is spinning and going up pipe 15 in the water.As Fig. 1: tube connector 29 is screwed in the lower end of water support 16, and last water support casing is contained in the water outer tube 19, and last water outer tube upper end is installed with valve body 10, and outer floating drum 20 is sleeved on outside the water outer tube; And it is fixing with fixed bit nut 26.Interior floating drum 23 is sleeved in the outer floating drum, and the lower end of outer floating drum is installed with float-valve plug 30.Valve body lower portion has a delivery port 32, makes water pass through last water support and flows into water tank.There are 5 guiding ribs in the floating drum outside in described, and interior floating drum is provided with a counterweight lead 33, and weight is between 60g～100g.Shown in Fig. 3,4,5,6, the flowing water breach of movable valve plug, fixed valve plug is 6 sectors.

Whole operating principle: when going up water, water process tube connector enters the interior pipe of last water in the valve body, enter then in the back cavity of valve body, water makes movable valve plug and fixed valve plug from adhesive to the pressure of movable valve plug, and water enters inner chamber by the sector of valve body, and process flows into the upper end cavity of going up the water outer tube in the mouth of a river down again, at this moment, moisture becomes two-way, and one the tunnel flows into draining valve through water supplement port carries out moisturizing, and another road is gone in the water tank through the cavity flow of last water support.Outside the water surface is completely crossed during the top of floating drum, water inwardly flows into outflow, floating drum upwards floated in buoyancy of water made, at this moment, the elongated slot of interior floating drum upper end drives starting handle and moves upward, and rotating shaft is rotated, and driving movable valve plug rotates, when interior floating drum upwards put in place, movable valve plug was just closed the sector notch of fixed valve plug, and water stops to inject water tank and moisturizing.Be closed condition of the present utility model at this moment.When draining valve bled off the water in the water tank, outer floating drum lower end float-valve plug was downward, opens the breach of outer floating drum lower end, water in the outer floating drum flows into water tank by this breach, at this moment, interior floating drum has lost buoyancy, under the effect of self counterweight, the resistance that overcomes spool moves downward, make the elongated slot drive starting handle of upper end downward, the band rotating shaft rotates counterclockwise, and rotating shaft drives valve core rotation, open the sector notch of fixed valve plug, water flows in water tank and the draining valve by sector notch again.Be opening of the present utility model this moment.So just can finish the unlatching overall process of tank intake valve of water repeatedly.
