And with taper valve opening constitute be tightly connected valve rod lower seal, the valve outlet be located at valve rod upper seal with it is close under valve rod
Between seal.When valve is opened, the freon in gas cylinder or gas tank can be flowed out by the runner of valve body.Such valve, although
Valve rod and handle can be positioned by insurance, but under some extreme cases such as strenuous vibration, it may appear that spool loosening is led
Poorly sealed situation is caused, freon leaks.
Summary of the invention
It is an object of the invention to overcome the defect of prior art, and provide a kind of freon gas cylinders for reducing freon leaks
Valve.
To achieve the goals above, the present invention uses following technical scheme：
A kind of freon gas bottle valve, including valve body and valve rod, the valve body is interior to be equipped with runner, is arranged in the middle part of the valve rod
Gasket, the runner middle part are equipped with the valve opening cooperated with gasket, and the valve body is equipped with the outlet being connected to runner top
And the import being connected to runner lower part, the runner is interior to be equipped with spring base, and the spring base, which is equipped with, pushes valve rod close to valve
The spring in hole, the spring base are equipped with through-hole, and the valve plate of rotation connection is equipped in the through-hole, is equipped in the spring base
The sliding block that valve rod opens valve plate under driving.Valve is fixed on freon gas cylinder, when valve rod moves down, by gasket and cooperation
Valve opening separation, when valve rod is displaced downwardly to shoe contact, band movable slider move down make valve plate rotation through-hole is opened, runner top
The inlet communication with runner lower part is exported, the freon in gas cylinder enters in the runner of valve body, and flows out valve body from outlet.?
When by strenuous vibration, although slight displacement can occur for valve rod, since valve plate is always maintained at closed state, freon
It will not be sprayed from outlet, freon leakage can be effectively prevent, improve valve safety.
Preferably, be equipped with the upper positioning disk and lower positioning disk of parallel arrangement in the middle part of the valve rod, the upper positioning disk and
The gasket locating slot for accommodating gasket is formed between lower positioning disk.In this way, gasket can strong fix on valve rod, avoid close
Packing slides with respect to valve rod.
Preferably, outer edge of the gasket close to valve opening one end is equipped with sealing cone, the sealing cone and valve
Hole sealing cooperation.Sealing cone has preferable centring property, realizes and the good sealing fiting effect of valve opening.
Preferably, the top surface edge of the upper positioning disk is equipped with the up-small and down-big guiding conical surface, the guiding conical surface
With the outer surface smoother transition of valve rod.In this way, gasket is nested on valve rod during installation, guiding conical surface guiding is convenient for gasket
It enters between positioning disk and lower positioning disk.
Preferably, the spring base is equipped with, axially consistent location hole, the valve rod and location hole are sliding with runner
Dynamic cooperation.Location hole is equipped with valve rod and is positioned by location hole, and valve stem slides are oriented to by location hole, guarantees valve rod shift position
Accurately, valve opening and closing precision is improved.
Preferably, the valve plate includes plate body, the one end at the close spring base center of plate body and through-hole wall rotation connect
It connects, hinged connecting rod is equipped between the plate body and sliding block, the spring base moves up drive plate body pass equipped with sliding block is acted on
The sliding block spring of through-hole is closed, the plate body lower end is equipped with the body of rod with valve stem contacts.In this way, when valve rod does not act on sliding block,
Sliding block is maintained at stroke top dead center position in sliding block spring effect, and plate body is maintained at the state for closing through-hole.And work as sliding block
When moving down, under connecting rod drive, plate body opens through-hole.
Preferably, the plate body is inclined in through-hole.When valve plate is not affected by valve rod effect, freon is flow to
It is acted in through-hole on the plate body of valve plate, plate body and through-hole can be made to be fitted close, further increase the sealing effect of plate body
The beneficial effects of the invention are as follows：When with respect to valve opening slight displacement occurs for gasket, valve is still able to maintain sealing state, has
Effect prevents freon from surprisingly spraying, and improves valve safety.
Detailed description of the invention
Fig. 1 is a kind of structural schematic diagram of the invention.
In figure：Valve body 1, valve opening 1a export 1b, import 1c, runner 1d, gasket 2, sealing cone 2a, spring 3, valve rod
