Abstract

The utility model relates to a cistern valve, particularly a cistern valve of a flush toilet. The utility model is composed of a valve cover, a valve seat and an anti-overflow pipe, wherein the valve cover is composed of a vacant shell cover and a hollow cover handle, the edge of the vacant shell cover is covered on the edge of the valve seat which is communicated with an anti-overflow cover, a side connecting supporting point is arranged between one side of the vacant shell cover and the anti-overflow pipe, and a threading hole is arranged on the cover. The utility model is characterized in that the edge of the vacant shell cover is provided with a circular iron sheet and a circular sealing sheet, and the edge of the valve seat is provided with magnetic steel. The utility model has the advantages of durability and little possibility of water leakage.

Description

Radiator valve

The utility model relates to radiator valve, particularly the toilet flush valve.

The structure of the toilet flush valve that existing and the utility model are close most as shown in Figure 1, it comprises that valve gap, valve seat, anti-overflow pipe form.Valve gap is joined by ghost housing 2 and hollow cap handle 4 and constitutes, and when valve gap covered on valve seat, the edge 3 of valve gap housing covered on the edge of valve seat 5, and the retaining in the water tank can not be entered in the valve, and this moment, valve was in closed condition.6 is rubber washer among the figure, and 7 is hexagonal (hexagon)nut, and both are used for valve seat 5 is sealingly fastened in the water tank bottom surface.Water in water tank is filled it up with certain altitude, if there is seepage in inlet channel, when still intaking, unnecessary water can overflow by being installed in the anti-overflow pipe 8 feeding valve seats on the valve seat, makes water tank keep certain water level.Through wires hole 1 is arranged on the valve gap cover 2, and the release pull of valve ties up on the through wires hole 1.Valve gap cover one side with support that anti-overflow pipe 8 is connected on have one to connect fulcrum, during opening valve, as long as pulling water tank backguy, hollow valve gap floats, and the water in the water tank is emitted from valve seat 5, and valve gap falls automatically by self gravitation again and is combined on the valve seat, valve cuts out again, water tank begins retaining again, and 9 is alignment pin among Fig. 1, gives the support that connects housing and anti-overflow pipe location.The valve gap of radiator valve shown in Figure 1 is pressed into a hollow integral with elastomeric material, the valve seat plastic production.After service time was long slightly, the valve gap of rubber material was aging, and elasticity reduces, and makes valve gap edge 3 discontinuity, with the sealing reduction at valve seat 5 edges, the seepage of water took place easily, caused " toilet leaks " phenomenon, serious waste water.

The purpose of this utility model is to provide a kind of prolonged use still to be difficult for the radiator valve of the seepage of generation water.

The utility model is made up of valve gap, valve seat, anti-overflow pipe.Valve gap is made of hollow housing and hollow cap handle, the periphery cover of housing is combined on the edge of valve seat, valve seat communicates with anti-overflow pipe, housing one side with support that anti-overflow pipe is connected on have one to connect fulcrum, through wires hole is arranged on the housing, at the edge of housing iron plate and diaphragm seal are installed, magnet steel are installed at the edge of valve seat.

Owing to iron plate and diaphragm seal are installed at the edge of housing of the present utility model, edge at valve seat is equipped with magnet steel, when valve was in closed condition, the magnetic line of force of said magnet steel saw through diaphragm seal, the iron plate that tightly attracts the housing edge to install, the edge that makes housing tightly seal cover is combined on the edge of valve seat, valve cuts out very firmly, even the prolonged use of valve, the still sealing of maintaining valve, be difficult for taking place the seepage of water, can guarantee to reach the purpose of this utility model.

Fig. 1 is the side view cutaway drawing of existing (flush toilet) radiator valve;

Fig. 2 is in the side view cutaway drawing of opening for the utility model;

Fig. 3 is in the side view cutaway drawing of the state of covering for the utility model;

Below in conjunction with description of drawings embodiment.

See Fig. 2,11 is the through wires hole on the valve gap housing, and 12 is the ghost housing, and hard plastic injection molding can be used in housing 12 and edge thereof.13 for being installed on the corrosion protection iron plate (for example tinplate sheet) at housing edge, can imbed the housing edge with bonding installation of marine glue or direct injection moulding.14 for being installed on the diaphragm seal on the iron plate, can be bonding with marine glue.15 places, edge at valve seat 17 are equipped with magnet steel 16, can be with common magnet steel.Anti-overflow pipe 20 communicates with valve seat 17.One side of valve gap cover 12 with support that anti-overflow pipe 20 is connected on have one to connect fulcrum, 21 be alignment pin, locatees for the support that connects housing and anti-overflow pipe.18 is rubber washer, and 19 is hexagonal sieve cap, and both are fixed in valve base sealing on the water tank bottom surface.Iron plate 13 and diaphragm seal 14 the bests of being installed on the housing edge are respectively the annular sheet, and the magnet steel the best of installing at the edge of valve seat is a torus, and are as shown in Figure 2, so stressed more symmetrical and even.Certainly, iron plate 13, diaphragm seal 14 and magnet steel 16 can not be circular ring plate or torus also, for example are the sectioned pieces or the segmented body of symmetry arrangement, as long as magnet steel and iron plate have attraction uniformly each other.Hollow cap handle 10 is connected with ghost housing 12, can connect or is threaded etc. with marine glue gummed.Lid handle 10 can be with moulding injection moulding firmly, and diaphragm seal 14 can be with material such as rubber or flexible plastics.

The component title that each label notes shows among Fig. 3 is identical with Fig. 2, and annular iron plate 13 is superimposed on thick black line segment position with ring packing sheet 14 among the figure.
