Abstract
The invention discloses an aerosol valve assembly featuring an internal valve stem sleeve. The sleeve serves to stabilize the movement of a valve stem, preventing the angular displacement of the valve stem sealing surface relative to the functional edge of the valve. Unrestrained angular displacement between the valve stem sealing surface and the functional edge of the valve is a hazard when fitting nozzles and controlled dosage metering devices as it can cause an unintended violent unchanged discharge of product from a container.
Description
Technical field
The present invention relates generally to a kind of valve, especially but be not to relate to the valve that is used for aerosol container uniquely with central valve rod.
Background technology
Aerosol container is to be used to store the little hermetically sealed container that can distribute goods.This aerosol container typically comprises circle tube tank, at the top of this circle tube tank valve seat is installed, and this valve seat is equipped with the valve that is installed in central authorities.This valve typically is installed on the inside face of valve seat, and can operate this valve via the valve rod that stretches out from the hole of valve seat central authorities.
In order to distribute goods from container, be installed on the valve seat and be sealed on the external part that touches of valve rod such as the actuating device of nozzle or controlled doses metering valve etc.Pushing actuating device moves to valve rod to be installed in the valve body in the container vertically.Push that function edge that valve rod makes valve separates with the valve stem seal face so that flow of articles through valve.
Consider the factor of safety and product life, expectation be to keep actuating device to separate before the goods with valve rod up to using.This needs the end user must actuating device be connected on the valve rod.Usually must manually accomplish this operation and not by means of assembling tool.
Traditional aerosol valve is not suitable for the manual installation actuating device.Subject matter is that the valve rod in the conventional valves just receives faint constraint and overcomes angular deflection.It is because the pressure in the container and the power of valve spring fully that valve rod can remain on vertical position.Following situation is much: in the treating process that manually actuator is installed on these valves; Make valve rod angular deflection to such degree: promptly; The ground, function marginal portion of valve does not contact with valve sealing element, can cause goods from valve, to be discharged fast tempestuously.Particularly when poisonous or flammable product is discharged this with abnormally dangerous.
Summary of the invention
The disclosed novel valve assembly of the present invention can limit valve rod and produce angular deflection.This will improve convenience and safety when manually being connected to actuating device on the aerosol container significantly.
According to an aspect of the present invention, a kind of aerosol valves door assembly is provided, comprises: valve body, its connection also is sealed on the valve seat; And valve pocket, it is assemblied in the top of said valve body; Wherein, the lower edge of said valve pocket is positioned on the elastic valve sealing member and to said sealing member and seals, so that the lower surface of said sealing member forms the valve function edge.
In addition, according to aerosol valves door assembly of the present invention, said valve function edge can be arranged to be installed to said valve body on the edge in aperture of any goods packaging bag consistent vertically.
In addition, according to aerosol valves door assembly of the present invention, said valve body and said valve pocket can be tubuloses.
In addition, according to aerosol valves door assembly of the present invention, said valve member can have the valve rod that is driven by the compression spring that is installed in the said valve body.
In addition, according to aerosol valves door assembly of the present invention, wherein, the upper gap of said valve rod is coupled in the said valve pocket.
In addition, according to aerosol valves door assembly of the present invention, wherein, said valve rod passes said valve sealing element, and said valve sealing element seals the cross connection hole in the said valve rod.
In addition, according to aerosol valves door assembly of the present invention, said valve member can comprise the valve pocket and the elastic valve sealing member of combination.
In addition, according to aerosol valves door assembly of the present invention, said valve member can comprise the feather valve shaft seal in the groove that is installed in the said valve rod.
In addition; According to aerosol valves door assembly of the present invention, said valve member can have such function: promptly, said valve rod is crank motion vertically; So that when said valve rod is in the extended position of its topmost; The back seal face at valve stem seal edge contacts and seals the lower edge of said elastic valve sealing member, and when pushing said valve rod, said back seal face leaves the lower edge of said elastic valve sealing member; Flow thereby can make goods center on said valve rod, thereby to make goods flow out said valve rod through the cross connection hole that connects said stem exterior surface and endoporus.
Description of drawings
Fig. 1 is for showing the aerosol valves door assembly of the embodiment of the invention;
Fig. 2 is the reduced form of the valve member of the demonstration embodiment of the invention; And
Fig. 3 is the another kind of form of the valve member of the demonstration embodiment of the invention.
The specific embodiment
With reference to accompanying drawing, the valve rod 1 with extension, the valve body 2 that extends and the aerosol valves door assembly of tubular valve sleeve 3 have been shown among Fig. 1.The valve of AA cutaway view 1 along the line to show that valve that the left side is closed and right side are opened.This valve is driven by valve spring (compression spring) 4.Engaging (staking) through the stake formula mechanically is installed to this valve member on the valve seat 5.The upper limb sealing elastomer sealing member 6 of the upper limb of valve body 2 and valve pocket 3, and this elastomeric seal seal valve seat 5.The lower end of valve rod is characterised in that it has the periphery sealing the margin, and this periphery sealing the margin comprises sealing surface 14.The lower edge of tubular valve sleeve 3 is positioned on the elastic valve sealing member 7 and to sealing part 7 and seals.Valve rod 1 passes valve sealing element 7, the cross connection hole 12 in these valve sealing element 7 sealed valve stems 1, and the lower surface of this valve sealing element 7 is as valve function edge 8.
Goods packaging bag 9 is being installed in the exterior situation of valve body, this packaging bag is through resilient packing bag sealing member 10 sealed valve bodies.This packaging bag 9 can remain on position 15 so that the edge in the aperture in the packaging bag is consistent vertically with valve function edge 8 through retainer 11.
Like this valve is operated: promptly, when closing this valve (shown in left side among Fig. 1), valve stem seal face 14 sealed valve function edges 8.When opening this valve (shown in right side among Fig. 1), valve stem seal face 1 separates with valve function edge 8 so that the gap 17 of flow of articles through so forming.Thereby goods can get into the cross connection hole 12 in the valve rod and flow out valve rod.Centre hole in the elastomeric seal 6 has formed the slipper seal of the outside face of sealed valve stem 1.
The reduced form that has shown valve member among Fig. 2, and obtain this reduced form through omitting valve sealing element 7.Require valve pocket 3 to process the function that can realize valve sealing element 7 simultaneously to the transverse stabilization function of valve rod by suitable material to provide.In this case, the lower edge of valve pocket 3 is sealed directly on the valve stem seal face 14.These, the lower edge of valve pocket 3 (feather edge) becomes valve function edge 8.This function edge 8 can adopt multiple shape so that sealing.
Shown the embodiment that is different from Fig. 2 among Fig. 3, wherein elastic sealing element 16 is inserted in the stem groove 13.The upper surface of sealing part becomes valve stem seal face 14.
