Abstract

The utility model relates to a water discharging valve, which comprises a water discharging pipe, a plug, and a water discharging pipe seat, wherein, the upper part of the water discharging pipe is screwed with the water discharging pipe seat, and the lower part of the water discharging pipe is fixed with a water container through a fixing nut and a sealing gasket; the periphery contact surface of the circular plug is arcuate, and the middle of the periphery contact surface is embedded with a sealing ring; the inner side of an opening of the water discharging pipe is a concave arcuate surface matched with the arcuate contact surface of the plug. The utility model has the advantages that the plug is prevented from escaping from the pipe opening. The utility model also has the advantages of simple structure, reasonable structure, convenient installation and operation, and low cost, and the utility model is suitable for being arranged and used in bathtubs, vegetable basins, and wash-basins.

Description

Draining valve

The utility model relates to a kind of dewatering installation, specifically a kind of draining valve.

As everyone knows, bathtub, nappy, washbowl etc. all are provided with outfall and link to each other with gutter, and usually its outfall all is provided with rubber stopper, block up during water storage, take down during draining.Need when therefore using discharge water through twice above action, actuating range is big, and more loaded down with trivial details, and stopper separates with outfall, also loses inconvenience easily.Also have at present and install ad hocly by the formula switch nearby on outfall, will press it or put on during draining, this also needs perseveration, and this switch is many because of component, easily breaks down in the junction, and cost is also high, should not apply.

The purpose of this utility model is exactly in order to overcome above-mentioned the deficiencies in the prior art, provides a kind of simple and reasonable for structure, easy to install, and cost is low, is applicable to that being installed in bathtub, nappy etc. goes up the novel draining valve that uses.

For achieving the above object, a kind of draining valve, it is provided with gutter, stopper, draining base, gutter top is threaded with the draining base, the bottom is fixed on the water vessel by last jack panel and sealing mat, it is characterized in that the peripheral contact surface of cylinder plug is curved, and the centre is embedded with sealing ring, inboard, gutter mouth of pipe place is cancave cambered surface, matches with the stopper arc contact surface.

Sealing ring on the utility model cylinder plug can closely contact with the mouth of pipe that it matches, the sealing water storage.During draining, cylinder plug does not break away from the mouth of pipe, and it is an axle with any two contact points of the mouth of pipe, can erect draining, and the utility model is simple in structure, easy to use.

The utility model will be further described below in conjunction with accompanying drawing:

Fig. 1 is the utility model textural association schematic diagram, and Fig. 2 is the utility model hull-borne schematic diagram.

As can be seen from Figure 1, a kind of draining valve, it is provided with gutter 1, cylinder plug 2, draining base 5, be fixed on bathtub, the nappy etc. for the ease of gutter, gutter 1 upper end is threaded with draining base 5, the bottom is fastening by last jack panel 8 and sealing mat 7, and draining base lower end also is provided with sealing mat 6.Cylinder plug 2 is positioned at the draining mouth of pipe 4, and the peripheral contact surface of itself and the mouth of pipe is curved, and the centre is embedded with sealing ring 8, and inboard, gutter mouth of pipe place is cancave cambered surface, matches with the stopper arc contact surface.The external diameter of stopper is slightly larger than the internal diameter of draining base 5 upper edges, and therefore, stopper can not break away from the mouth of pipe.The lower end of the utility model gutter 1 can also connect various gutters 9 down.

When the utility model uses, at first fix a drainpipe 1 in the outfall bottom of bathtub, nappy or washbowl, its upper end is fixing with draining base 5, and the lower end is fastening by last jack panel 8.When being filled with water, with finger stopper 2 is rotated to the position equal with outfall 4 in outfall 4, this moment, the sealing ring 3 of stopper combined with outfall is tight, can be used to be filled with water.During draining, because the external diameter of stopper is greater than draining base internal diameter, so it can not break away from the mouth of pipe, stopper is in outfall, and the diameter that is linked to be with any two contact points is an axle, needs only gently one by erecting draining, as shown in Figure 2.

The utility model is rational in infrastructure, and is easy to install, and cost is low, is applicable to be installed on bathtub, nappy, the washbowl to use.

Claims

1, a kind of draining valve, it is provided with gutter, stopper, the draining base, gutter top is threaded with the draining base, and the bottom is fixed on the water vessel by last jack panel and sealing mat, it is characterized in that the peripheral contact surface of cylinder plug is curved, the centre is embedded with sealing ring, and inboard, gutter mouth of pipe place is cancave cambered surface, matches with the stopper arc contact surface.
