CN2378583Y - Ceramic core water sealing lower water tank fitting feeding valve - Google Patents

Abstract

The utility model relates to a water supply valve used for a low water tank, which belongs to a low water tank fitting which has the advantages of water saving and high durability. The utility model is characterized in that the utility model is combined by two ceramic chips with different shapes, and the ceramic chips have the advantages of no distortion, no aging and long service life. Rotating one of the ceramic chips can achieve the effect of water seal and can also achieve the purposes of water saving and high durability.

Description

Ceramic core water shutoff low cistern accessory water supply valve

The water supply valve of using on a kind of low cistern accessory belongs to the short-life accessory of joint.

The low cistern accessory of using on the toilet seat all is to adopt the rubber pad water shutoff at present, as shown in Figure 1: the 1st, cylinder shape valve; The 2nd, pad; The 3rd, tightly be enclosed within the ring washer on the valve body 1; The 6th and the close-fitting valve seat in cylindrical bottom; The 7th, tightly be embedded in the rubbery flat gasket in the valve seat 6, this is the low cistern water supply valve that adopts the rubber water shutoff.

The purpose of this utility model be overcome existing low cistern water supply valve all be adopt easily aging, flexible type, the rubber pad water shutoff of cracky, and provide a kind of, anti-modification, the low cistern water supply valve of breakage resistant ceramic chip water shutoff by ageing-resistant.

The purpose of this utility model is achieved in that by the water supply valve body and is connected with ceramic core body that ceramic core body is connected with the ceramic plate rotatingshaft, and the ceramic plate rotatingshaft is connected with ceramic plate, form ceramic core water shutoff low cistern water supply valve.

Use proof: the use of ceramic core water shutoff is received a mandate, and the use that has surpassed the rubber pad water shutoff is greatly received a mandate.

In order in conjunction with example the utility model to be done detailed description below, now as follows employed accompanying drawing title in the application documents and numbering brief introduction:

Fig. 1, the water supply valve longitudinal section of using with the low cistern of rubbery flat gasket 7 water shutoffs;

Fig. 2, the longitudinal section that the utility model proposes with ceramic core water shutoff low cistern water supply valve;

Fig. 3, be the fixing front view of ceramic plate;

Fig. 4, be the front view that rotates ceramic plate;

Fig. 5, be the structural representation of low cistern.

Embodiment;

Ask for an interview Fig. 2: the 1st, spline, the 2nd, the ceramic plate rotatingshaft, the 3rd, valve core, the 4th, rotate ceramic plate, the 5th, the water supply valve body, the 6th, outlet pipe, the 7th, intake pipe, the 8th, fixing ceramic plate, the 9th, the ceramic plate gap, Fig. 5 is the scheme of installation of water supply valve in low cistern, the 15th, and sewer, the 13rd, following water cover plate, the 19th, handle discharges water, the 12nd, ball float, it is through the spline connecting rod, 18 drive 2 poppet shaft rotation among Fig. 2, also band changes the rotation ceramic plate 4 that tightly is embedded on the ceramic plate rotatingshaft simultaneously, play the water shutoff effect, when water had been put, ball float 12 sank, drive the ceramic plate rotatingshaft by spline connecting rod 18, the rotation ceramic plate rotates, connect the intake pipe of water supply valve 16, passing through offlet, 17 add water in water tank.

Use proof, effect is very good.

Claims (1)

1. water supply valve that low cistern is used, contain water supply valve body (5), pottery core body (8), ceramic plate rotatingshaft (2), rotate ceramic plate (4), it is characterized in that: water supply valve body (5) is connected with ceramic core body (4), and ceramic core body (8) is connected with ceramic plate rotatingshaft (2), and ceramic plate rotatingshaft (2) is connected with rotation ceramic plate (4).
