Abstract
The present invention relates to a valve which is mainly composed of a piston barrel and a piston sleeve, wherein the piston barrel is provided with water filling holes uniformly and symmetrically distributed, and the piston sleeve can smoothly slide along the piston barrel. Thus, the water filling holes can be opened and closed, and then the valve is opened and closed.
Description
The present invention relates to a kind of valve structure, be mainly used in water tap, automatic water level control valve and the various solenoid valves that use for automatic control system.
Valve be produce, one of the most universal widely used necessity in the life, but the basic structure of valve and on-off principle do not change over a hundred or so year, all to be that valve is one-sided bear huge water pressure to its general character, must just can fasten valve with very big external force.So valve mechanism is complicated, volume is big, cost is high, use not nimble, and fragile, easy to leak.Appearance design is difficult for attractive in appearanceization.
Task of the present invention is exactly that a kind of brand-new valve mechanism will be provided, to eliminate the above-mentioned disadvantage of conventional valves.Make adopt all kinds of valves that structure of the present invention manufactures to open and close required external force very little, and be subjected to the pressure size of working medium (as gas, liquid) and the influence that changes thereof hardly.
The object of the present invention is achieved like this: valve mechanism of the present invention mainly is made of piston cylinder, piston sleeve etc.An end that it is characterized in that piston cylinder is connected with the inlet pipe of working medium (as gas, liquid), the other end sealing; Some water outlets that are symmetrically distributed about the medial axis of piston cylinder are set on piston cylinder; Piston sleeve is enclosed within on the piston cylinder outer wall, and can be along the flexible slippage of piston cylinder, when piston sleeve is in sealing water outlet position (this moment the piston cylinder outer wall with the piston sleeve inwall between become to be sealed and matched), valve closing; When piston sleeve slid off water outlet, liquid (or gas) was through water outlet ejection, i.e. valve opening.Because water outlet is to be symmetrically distributed along piston cylinder and about the medial axis of piston cylinder, the pressure of working medium is cancelled each other to the active force of " valve "-piston sleeve.The influence that the open and close of " valve " just are subjected to its working pressure size hardly and change, the slippage piston sleeve is very agile, and promptly the required external force of switch " valve " is very little.
Referring now to accompanying drawing embodiments of the invention are described.
Accompanying drawing 1 is the orthogonal view of valve mechanism of the present invention.
There is a piston cylinder (1) to be enclosed within on neck bush (5) outer wall, and sealing and fixing; It is movingly between the two that piston sleeve (3) is enclosed within on the piston cylinder (1).Piston sleeve (3) can be along the slippage flexibly up and down of piston cylinder (1) outer wall.Neck bush (5) one ends are connected with water pipe (4), the other end sealing.(block piece that closed end has prevention piston sleeve (3) to come off).Some water outlets (2) that are symmetrically distributed about the medial axis of piston cylinder (1) are set on piston cylinder (1), and water outlet (2) sees through neck bush (5) and cross current.When outer active force makes piston sleeve (3) along piston cylinder (1) slippage up and down, when moving apart or closing water outlet (2), just open or close tap water.
Accompanying drawing 2 is orthogonal view of using the automatic water level control valve that said structure makes.Its structure and working principle are as follows: piston sleeve (3) embeds in the floating drum (7), utilizes buoyancy and gravity to drive piston sleeve (3) and moves up and down along piston cylinder (1).Tap water by water pipe (4), neck bush (5) in water outlet (2) outwards sprays into water tank (6).When water level rose, the buoyancy of floating drum (7) drove piston sleeve (3) and rises until sealing water outlet (2), stops into water; When water when flush port (8) is discharged, the drawdown in the water tank (6), floating drum (7) also descends under action of gravity together with piston sleeve (3), the water filling until opening water outlet (2).So can make the interior water level of water tank (6) remain on the height of setting.
Accompanying drawing 3 is orthogonal view of a kind of water tap.Piston sleeve (3) embeds in the coating part (9), and block piece (10) can move down position-limiting action to coating part (9).Coating part (9) upper end has L shaped draw-in groove (13), and the lower end is threaded with nozzle (11).Bayonet lock (12) on the neck bush (5) be used for " tangling " coating part (9) and by with adjust the degree of closure of piston sleeve (3) cooperating of L shaped draw-in groove (13) to water outlet (2), thereby regulated water-outlet quantity.During use, grasp coating part (9), carry out water-outlet quantity and regulate operation.Bayonet lock (12), draw-in groove (13) structure can substitute with other multiple ways.Introduction is omitted.
Claims (1)
1, a kind of valve mechanism mainly is made of piston cylinder, piston sleeve, it is characterized in that: piston cylinder one end is connected with the working medium inlet pipe, the other end sealing; Some water outlets that are symmetrically distributed about the medial axis of piston cylinder are set on piston cylinder; Piston sleeve is enclosed within on the outer wall of piston cylinder, and can slide flexibly along piston cylinder; When piston sleeve is in when sealing the water outlet position fully, between piston sleeve and the piston cylinder for being sealed and matched; Promptly by piston sleeve along the slippage of piston cylinder be sealed and matched make with the closed piston tube on water outlet, thereby play the open and close effect of valve.
