Abstract
The utility model relates to a plug self-closing water tap. In the utility model, a valve cavity on the upper part of a valve body is provided with a piston valve which is opened and closed by a handle, a gear, a valve rod with teeth, and a spring. The utility model has the advantages of reasonable design, simple structure, low cost, good manufacturability, convenient maintenance, reliable self closure, long service life, etc.
Description
The utility model relates to a kind of running water tap that can be self-closing.
It is reported that the running water tap form that has self-closing function at present is varied, the water-stopping self-closing water of producing as the gold Long Qichepeijianchang of: Shenyang City is chewed (CN902134949) etc.Though these water taps have played positive role aspect water saving, all in various degree have a complex structure, cost height, inconvenient maintenance and installation, self-closing poor reliability, deficiency such as working life is short.
The purpose of this utility model is, for the deficiency that overcomes above-mentioned water tap provides a kind of reasonable in design, simple in structure, cost is low, and good manufacturability is convenient to maintenance and installation, the self-closing running water tap of plug formula of self-closing reliable, long service life.
Technical solution of the present utility model is, for simplified structure, be easy to manufacturing, perisporium be housed in the valve pocket on tap valve body top be provided with the seal ring lower end and be provided with and the piston valve of the seal ring of boss contact at the bottom of the valve pocket or pad and the valve rod that has tooth that is connected with piston valve and the spring that is located at piston valve top.Top at the gland that has valve rod hole is provided with gear stand.On gear stand, be equipped with and valve rod tooth meshed gears.On the axle of gear, be provided with handle.Get rusty or protect gear in order to prevent that gear from contacting with water, be provided with guard shield on the top of gland.The seal ring that is located at the piston valve lower end also can be located on the end boss of valve pocket.
The utility model compared with the prior art, owing in the valve pocket on valve body top, be equipped with by handle, gear, have the valve rod of tooth and the piston valve that spring opens and closes, therefore it is reasonable in design, simple in structure it have been had, and cost is low, good manufacturability, be convenient to maintenance and installation, self-closing reliable, advantages such as long service life.
Description of drawings of the present utility model, 1 in the accompanying drawing is tap valve body, the 2nd, screw, the 3rd, sealing gasket, the 4th, piston valve, the 5th, seal ring, the 6th, spring, the 7th, gland, the 8th, valve rod, the 9th, guard shield, the 10th, gear, the 11st, gear stand, the 12nd, handle, the 13rd, valve pocket, the 14th, catch.
Below in conjunction with accompanying drawing, describe a specific embodiment of the present utility model in detail.
Fig. 1 is a structural representation of the present utility model.
Referring to Fig. 1, in the bottom on tap valve body 1 top has the cylindrical shape valve pocket 13 of boss, the piston valve 4 that adapts with valve pocket 13 is housed.Perisporium car on piston valve 4 tops has a circle o-ring groove, and seal ring 5 is housed in groove.Lower end at piston valve 4 is fastened with sealing gasket 3 by screw 2 and catch 14.Seal ring 5 and sealing gasket 3 are made by rubber.Center car in piston valve 4 upper ends has tapped hole, is screwed with the valve rod 68 that upside has tooth in tapped hole.On valve rod 8, be with spring 6.Valve pocket 13 suitable for reading the gland 7 that has valve rod hole is arranged by screw threads for fastening.Be fastened with the gear stand 11 of two symmetries by screw on the top of gland 7.Gear 10 is housed on gear stand 11.On the axle of gear 10 1 sides, be fastened with handle 12 by nut.Be with guard shield 9 on the top of gland 7.
During use, according to water consumption handle is pulled diverse location downwards, at this moment, piston valve is hovered on the certain position by buoyancy of water and recoil force.When closing, upwards pull handle and make piston drop to closed position.When piston valve is in opening state because the user forgets and closes, when cutting off the water then the effect of piston valve by spring its whereabouts is closed automatically.
