Abstract

A kind of control valve unit of liquid gas cylinder has a valve member to be subjected to permanent load and leans on valve seat, and is connected with a pin, and pin is suitable to the valve positive opening.On this pin protector is housed, is used to prevent that sand grains or other impurity from entering valve seat.

Description

The present invention relates to a kind of control valve unit of liquid gas cylinder, it comprises valve body, is suitable for being fixed on the relief opening of cylinder barrel, be provided with valve seat towards cylinder barrel inside, be used for and valve member cooperates, valve member stretches out a pin at the valve seat exhaust side, can move vertically and with the valve positive opening.
In order to control moving of pin, the common working pressure control piece of user is installed in it on valve body.And after container is used sky, it is pulled down again, and refill at the filling station.
After control piece is removed, to be screwed on the relief opening with closing cap usually and valve is protected.Not all user observes this regulation, therefore, has sand grains or other Particulate Inclusion and enters into danger in the hole of laying control piece on the valve body.Because user's dereliction of duty, control piece also may be besmirched by impurity, when the installation and control part or afterwards, when opening valve, these impurity may fall down and enter valve seat.Though these clitaminating particles often are discharged from gas and blow open, but can be blown open, they disturb the function of valve probably thereafter, especially hinder it and close fully, therefore have the danger of catching fire or exploding, and they also increase the wearing and tearing of valve member and valve seat.
Above-mentioned shortcoming can be eliminated by the present invention, with the pin on the valve member with liner ring around, this sleeve is provided with flexible flange disk, at least almost extends on valve chamber's internal surface from pin.
Flange disk on the sleeve, the impurity that may arrive the key area of valve collects, and is retained in harmless place until container is used empty.Before refilling, valve can be blown off next time.But this does not need, because flange disk has elasticity, flowing of blanketing gas can make impurity be brought in the cylinder, and impurity is harmless in cylinder.
Below in conjunction with accompanying drawing in detail the present invention is described in detail, Fig. 1 is the fragmentary axial cross-section of liquid gas cylinder control valve unit of the present invention.
Valve body 1 top that has shown the control valve unit of liquid gas cylinder among the figure, this control valve unit can be provided with flange 2 at its top with being threaded or being welded to (not shown) on the cylinder, and the control piece of known type can be installed above.Valve body 1 has the downward valve seat 3 that cooperates with valve member 4, shown in valve member 4 are tapers, can make by rubber or similar elastic material, taper bead 5 same on valve member 4 and the pin 6 is connected, pin 6 slightly upwards extend in the hole of laying control piece bottom 7, and control piece is suitable for controlling the exhaust by valve 3,4.Sealing gasket around part 7 of label 8 expressions is laid axle 9 in the part 7, when exhaust, 9 pairs of pins 6 of axle apply downward pressure, and this pressure has overcome the closed permanent power that acts on the valve member 4, and valve is opened.This closing force can be produced by air pressure in the cylinder and closing spring (not shown) respectively.
Sleeve 11 is installed in dwindling on the part 10 of pin 6, and this sleeve top and outside elastic flange dish 12 converge.Flange disk 12 at least roughly is stretched on chamber 4 internal surfaces 13 of valve body 1, is suitable for holding and keeping impurity, otherwise impurity may drop on the valve seat 3, results in blockage between this valve seat 3 and valve member 4.
In described embodiment, flange disk 12 is dish types, is configured on the pin 6, and when the operating position that is in as shown in the figure, its outer rim should prop up the ventricumbent mating face 15 in the chamber 14.This is to preventing that impurity from dropping to valve seat 3 additional protection is provided, and simultaneously, Auxiliary valves is played jointly in flange disk 12 and mating face 15, when valve 3,4 does not cut out fully, can prevent gas leakage.
When valve was opened, sleeve 11 was also dragged down, and made flange disk 12 leave mating face 15.Flange disk is resilient, be easy to be out of shape by gas pressure, so gas stream crosses its outer rim, though this outer rim is tended to become straight towards chamber wall 13 when stressed not having.
When container refilled, the gas of inflow overturn flange disk downwards, and valve 3,4 is opened.If impurity has accumulated on the flange disk surface, they will be blown off in cylinder, and they do not have harm there.
Antifouling or guard member of control valve unit of the present invention can realize with other method beyond the diagram.Should particularly point out, can use a kind of protector, its sleeve is fixed to chamber wall 13, and the inner edge of its flange disk contact with pin 6.

Claims (2)

1, a kind of control valve unit of liquid gas cylinder, comprise valve body, be suitable for being fixed on the exhaust port of cylinder barrel, be provided with the valve seat towards cylinder barrel inside, be used for cooperating with valve member, valve member stretches out a pin at the exhaust side of valve seat, be used for vertically moving and with the valve positive opening, the pin that the invention is characterized in valve member by a liner ring around, this sleeve contains resilient flange disk, at least almost extends to from pin on the internal surface of this valve chamber.
2, the control valve unit of liquid gas cylinder according to claim 1, it is characterized in that flange disk is a dish type, its recess is towards lifting off a seat on one side the configuration of sleeve on pin, the outer rim that should make flange disk when valve is in the closed position, inwardly prop up in the chamber towards the mating face.
