Abstract

The utility model relates to an anti-pressure anti-overflow water tap. A bowl shaped rubber pad is arranged between an upper cover and a valve body. The center of the upper part of the upper cover is provided with a thread hole in which a screw rod can be screwed. The bottom of the screw rod is provided with a groove. The upper end of a head valve can be inserted in the groove. The rubber pad is pressed by the head valve. When the utility model is used, the phenomenon of water leakage can not occur.

Description

Anti-pressure anti-overflow water tap

The utility model relates to a kind of withstand voltage overflow-proof tap, belongs to the technical field of architectural hardware.

Water tap is that every household uses, and its major defect is that the rubber rubber cushion is housed between valve rod and valve body, and it is easily aging again that it is neither withstand voltage, use soon that rubber cushion will damage, cause and leak, when opening tap, spilling water usually between screw rod and the loam cake causes the waste of water resources.

The purpose of this utility model is that a kind of withstand voltage overflow-proof tap will be provided, and it can overcome above-mentioned shortcoming.

The purpose of this utility model is to realize like this, screw rod upper end is that tapped hole is arranged at loam cake top, can be screwed into screw rod in the square square hole that can be inserted into handwheel, the screw rod lower end is fluted, the upper end of overhead-valve is that a cylindrical body can be inserted in this groove, and loam cake is connected with screw thread with valve body, and the bowl-type rubber pad is housed therebetween, its favorable sealing property, withstand voltage again, the life-span is longer, and its shape can guarantee to stop water leakage phenomenon.

The schematic representation of Fig. 1 is withstand voltage overflow-proof tap

Now in conjunction with the accompanying drawings the structure of withstand voltage overflow-proof tap is described in detail:

By Fig. 1, handwheel (1) can be two leaves or three leaf handle forms, it can be a circle wheel shape, there is square hole at its center, screw rod (2) upper end also is square, can be inserted in the square hole, loam cake (5) is a cone, and top is connected with a hexahedron, spanner easy to use is fixed, there is tapped hole at the center, and screw rod (2) can be screwed into thus, and a cirque body is extended in the cone lower end, has female thread (9), screw rod (2) lower end is connected with an overhead-valve (3) again, and overhead-valve (3) is a disc, and the middle part is connected with a cylindrical body, can be inserted in the groove (7) of screw rod (2) lower end, the faucet body that valve body (6) is commonly used is similar, and there is external screw thread (10) its upper end, just in time can match with the female thread (9) of loam cake (5), a rubber pad (4) that circle is bowl-shape also is housed between body cap (5) and valve body (6), its bottom is just in time compressed by overhead-valve (3), and valve body (6) right-hand member has helical thread portion (11), and right part has a hexahedron (12).

Because rubber pad (4) bottom surface and valve body interior edge face (8) fit, the upper-end surface of the left and right sides end valve body (6) of rubber pad (4) fits, loam cake (5) presses it again, thereby seal action is stronger, unlikely outside spilling water, rubber pad (4) is more withstand voltage again, and is not fragile, thereby can guarantee not have the defect of spilling water.

Compared with prior art, this Anti-pressure anti-overflow water tap has following advantages:

1, adopt bowl-shape rubber blanket, both the pressure-resistant seal performance was good, can thoroughly prevent the leakage of sealing.

2, simple in structure, easy to manufacture, cost is also low.

Claims

1, a kind of withstand voltage overflow-proof tap, it is characterized in that there is square hole at handwheel (1) middle part, screw rod (2) upper end also is square, can be inserted in the square hole, loam cake (5) is a cone, top is associated with a hexahedron, there is tapped hole in central authorities, can be screwed into screw rod (2), and the cone lower end is a cirque body, its female thread (9) matches with the external screw thread (10) on valve body (6) top, an overhead-valve (3) is equipped with in screw rod (2) lower end, and overhead-valve (3) is circular, and its upper end is connected with a cylindrical body, can be inserted in the groove of screw rod (2) bottom, between loam cake (5) and the valve body (6) a bowl-shape rubber pad (4) is housed.
