Abstract

The utility model discloses a new style new style delayed flush valve with quickly opening and closing function, which can be used for a public lavatory and a domestic toilet washing, and all the gas and liquid control system which need to delay and close automatically after opening in an industrial department. The valve not only has the effect of delaying time, but also reaches a reliable sealing effect according to the combined action of a positive-pressure piston type air delay device and a spring bellow, and combining with a stop valve. The structure of the utility model is mainly composed of a valve rod, a partition plate, a valve body, a spring bellow, a steel ball, a small spring, a needle-shaped adjusting screw, a seal rubber strip, an O-shaped circle piston body, a hydraulic cylinder and a valve rod. The utility model has the advantages of small size, low cost, good performance and can completely replace a current water storage tank and the toilet flushing device of a ball float system.

Description

Delayed flush valve with quickly opening and closing function

The utility model is a kind of fast open and close type automatic delayed by-pass valve control, is specially adapted to all needs of industrial department such as the flushing of public lavatory and home-use closet and light industry, electronics, food and opens in the gas of back automatic delay function, the liquid control system.

Existing lavatory flushing device for toilet is made up of a water storage tank and a cover ball float system, the cost height, transports that water supply volume can not be regulated, size is huge by being easy to fragmentation (porcelain water tank) in the process of assembling.The industrial department existing equipment, as the kinescope glass shell cleaning machine, loading onto glass bulb needs to open wash-out valve later on, and valve-off again after some seconds need " opening " " pass " secondary operation altogether, and scavenging period can not guarantee.

The purpose of this utility model is a kind of water storage tank and ball float system of can substituting fully of design, reaches the adjustable fast switching time-delay flushing valve of washing time.This valve cost is low, volume is little, using water wisely, be convenient to the transportation and by dress.

Open and close the synergy of time-delay flushing valve soon, and combine, reach automatic delayed and good sealing effectiveness with the cut-off type valve by malleation piston type air delayer and spring corrugated pipe.Its structure mainly is made up of valve rod, division board, valve body, spring corrugated pipe, steel ball, little spring, aciculiform adjustment screw, sealed rubber, O type circle, piston body, cylinder, valve rod.Cylinder block top has pressure compensation opening, and bus flare, division board are provided with unidirectional air inlet port and give vent to anger the adjusting mouth in its underpart.

The utility model is described in further detail below with reference to accompanying drawing.

Fig. 1 is the utility model structural representation.

Fig. 2 is that the utility model is given vent to anger and regulated a mouthful local enlarged diagram.

Fig. 3 is the local enlarged diagram of the unidirectional air inlet port of the utility model.

As shown in drawings, its structure mainly contains following part to be formed, and 1, lever, 2, division board, 3, valve body, 4, spring corrugated pipe, 5, steel ball, 6, little spring, 7, pin type adjustment screw, 8, sealed rubber, 9, " O " type circle, 10, piston body, 11, cylinder, 12, valve rod.Have pressure compensation opening on cylinder (11) top, bus is trumpet type in its underpart; Division board (2) is provided with unidirectional air inlet port and gives vent to anger and regulate mouth, and inside is equipped with steel ball (5), little spring (6) and aciculiform adjustment screw (7) respectively; Valve rod (12) top be provided with lever (1), middle part be equipped with " O " type circle (9) is housed on piston body (10), the piston body, the bottom is equipped with sealed rubber (8) and between sealed rubber (8) and division board (2) spring corrugated pipe (4) is housed, and has gas on the valve body (3), liquid is imported and exported.

When using this valve, hand lever makes on the valve rod and carries, and compresses spring corrugated pipe simultaneously and opens on valve, the piston and move, and cylinder first half air is driven out of by pressure compensation opening, and Lower Half is by unidirectional air inlet port air inlet; After manually finishing, bellows springs works, valve rod is pushed to the air of piston bottom in below, the compression cylinder together with sealed rubber and piston, because the air of piston bottom can only be regulated a mouthful discharge from giving vent to anger, as long as adjust capacity, piston, valve rod, sealed rubber can only slowly descend, and valve stays open; Bus horn mouth place in piston drops to cylinder body, piston communicates up and down in the cylinder, has lost the effect of air on the piston on the downforce horse back dummy piston, under the effect of spring corrugated pipe, valve rod, sealed rubber and piston descend rapidly, reach the effect of rapid-closure damper.Under the synergy of tap water (or other gas, liquid) pressure and spring corrugated pipe, strengthened the sealing effectiveness of sealed rubber.

Use the fast Delayed flush valve that opens and closes, open fully through manual late gate, delay the rapid autoshutdown of a period of time late gate, slack time is adjustable, be contained in and substitute water storage tank and ball float system on public lavatory and the home-use closet fully, reach the purpose of controlled flushing, reduced cost and saved water. It is simple in structure, be convenient to by dress, easy to use. At industrial department, after all needs are opened All can adopt this valve in any gas of automatic delay function, the liquid control system, on the kinescope glass shell cleaning machine, adopt this valve after, can guarantee scavenging period, improve cleaning quality as long as once open.

Claims

1, a kind of fast switching time-delay flushing valve of forming by valve body (3), cylinder (11), it is characterized in that being equipped with in valve body (3), the cylinder (11) to be equipped with on valve rod (12), the valve rod " O " type circle (9) is housed on piston body (10), the piston body, stem lower portion is equipped with sealed rubber (8); Cylinder top is provided with bus flare in the flat hole of pressure and stem through-hole, the bottom; Have on the valve body (3) be equipped with in the middle of gas, liquid import and export, valve body and the cylinder division board (2), above be provided with unidirectional air inlet port and give vent to anger and regulate mouthful.

2,, it is characterized in that the effect that combination by air type time-delay mechanism, spring corrugated pipe and cut-off type valve reaches fast unlatching, automatic delayed, closes soon according to right 1 described flushing valve.
