Abstract
The utility model belongs to the class of valves, in particular to a self-closing time-delay flushing valve. The utility model comprises a triple valve body with a jacket, the right end of the triple valve body is provided with a water inlet, the left end of the triple valve body is provided with a water outlet, and the upper end of the triple valve body is provided with a button with a push rod. The inner cavity of the valve body, which is arranged under the push rod, is provided with a piston with a valve needle, and a spring which is used for pushing the piston for a deferred action is arranged between the lower end surface of the piston and the bottom surface of the inner cavity of the valve body. The utility model which has the function of deferred self closing can be applied to a public place such as a latrine, a room prevents a phenomenon that water often flows and saves the water.
Description
The utility model relates to valve technology field, particularly a kind of delayed self-close flushing valve.
At present, the flushing valve that is used for public lavatory and shower does not all have the function of delay-self-closing, again because of open and close inconvenience, the phenomenon of perennial draingage often takes place.
The utility model is intended to overcome the above-mentioned defective of existing flushing valve, and a kind of delayed self-close flushing valve is provided, and can close automatically in limiting time after promptly opening valve, thereby stops perennial draingage.
For achieving the above object, technical solution of the present utility model is: installing one cover delay-self-closing mechanism in a special shape valve body.
Valve body is a threeway that has chuck, and its both sides are entery and delivery port, is equiped with a cover delay-self-closing mechanism in the upside mouth.
Delay-self-closing mechanism is made of core body, button, push rod, pressure cap, plug, sealing ring, pad, valve port, cylinder sleeve, piston, push rod, sealing mat, rubber ring, needle and spring.Core body by gland and screw in the upside mouth of valve body, and with seal and valve seal.A button that has a push rod is contained in the upper end of core body by pressure cap.The inner chamber of core body is equipped with plug, sealing ring and pad, is provided with drain hole around the inner chamber bottom of core body.A threaded valve port in two is equipped with in the lower end of core body, is connecting cylinder sleeve on the lower end screw thread of valve port.Around the cylinder sleeve top and bottom is provided with the inlet opening, and the cylinder sleeve inner chamber is equipped with piston and spring.Cylinder sleeve and piston seal with elastometic washer.Piston top is provided with push rod and sealing mat, and the bottom is provided with needle, between the inlet opening of needle and cylinder sleeve bottom certain clearance is arranged, and needle can move up and down in the inlet opening of cylinder sleeve bottom.
Operating principle of the present utility model and using method are: this valve is contained on the water pipe, and water is entered the inner chamber of valve body by the water inlet of valve body.When this valve when not working, owing to piston is subjected to the elastic force of spring and pushes valve port to by the thrust that inlet opening, cylinder sleeve bottom flows into water, piston makes it to be in normally off with inlet opening around the cylinder sleeve top and valve port sealing.
Press the button by push rod and push piston to the cylinder sleeve lower end, water in the valve inleting water mouth enters the cavity mouth that flows into the core body bottom in the cylinder sleeve again through valve port by the inlet opening around the cylinder sleeve top, and the chuck that enters valve body of the drain hole around its cavity flows to the delivery port of valve body again.
Release button, piston are risen by the elastic force of spring.Owing between the inlet opening of the needle of piston bottom and cylinder sleeve bottom certain clearance is arranged, can control the absorption speed of cylinder sleeve, thereby control piston rises slowly, reach the purpose of time-delay.When piston rises to the valve port bottom, promptly reach self-closing purpose.
Owing to take above-mentioned technical solution, the utility model advantage has two: one, and this opening of valves is convenient, only need press the button, and gets final product flowing water; The 2nd, but delay-self-closing behind this opening of valves both can regularly wash, again can be self-closing, thus stop perennial draingage.
Accompanying drawing is a structural representation of the present utility model.
Referring to accompanying drawing, valve body 1 is a threeway that has chuck, and both sides are entery and delivery port, with gland 17 and screw 18 delay-self-closing mechanism is installed in the upside mouth of valve body 1.Delay-self-closing mechanism is made of core body 13, button 15, push rod 10, pressure cap 14, plug 12, sealing ring 16, pad 11, valve port 9, cylinder sleeve 7, piston 4, push rod 8, sealing mat 6, rubber ring 5, needle 3 and spring 2.Core body 13 usefulness seals (19,20) and valve body 1 sealing.
