Abstract
A non-refillable cylinder valve includes a valve rod and a valve body, wherein the valve rod is inserted and mounted in the valve body, a filling mouth is arranged on a side edge of the valve body, a step matched with the lower part of the valve rod is arranged in the valve body below the filling mouth, the lower part of the valve body is fixedly connected with a base, an elastic sheet is mounted at the upper part of the base, an elastic ball is placed on the elastic sheet, the inner diameter of the middle part of the base is larger than that of the elastic ball, and the inner diameter of the lower part of the base is smaller than that of the elastic ball; and the lower end of the valve rod is placed right above the elastic ball. The invention provides the non-refillable cylinder valve with advantages of simplified structure and high production efficiency.
Description
Technical field
The present invention relates to a kind of cylinder valve.
Background technique
In the existing cylinder valve, do not possess identification usually and whether belong to the non-refillable function, also the someone has proposed the scheme of non-refillable, has complex structure, technological deficiency that manufacturing efficiency is low.
Summary of the invention
In order to overcome the low deficiency of complex structure, manufacturing efficiency of existing cylinder valves for non-refillable cylinder, the present invention provides a kind of simplified structure, cylinder valves for non-refillable cylinder that manufacturing efficiency is high.
The technical solution adopted for the present invention to solve the technical problems is:
A kind of cylinder valves for non-refillable cylinder comprises valve rod and valve body, and said valve rod is inserted in the said valve body; The side of said valve body is provided with charging air inlet, is provided with the step that matees with said stem lower portion in the valve body below said charging air inlet, and said valve body lower portion is fixedly connected with pedestal; Shell fragment is installed on the top of said pedestal; Place marble on the said shell fragment, said pedestal middle part internal diameter is bigger than said marble, and said pedestal bottom internal diameter is littler than said marble; The lower end of said valve rod be positioned at said marble directly over.
Further, said valve rod is threaded with valve body, and the joint is provided with seal ring.
Further, said pedestal is threaded with valve body lower portion.
The top installation insurance folder of said valve rod.
Place the bullet pad on the step between said pedestal middle part and the bottom, block is installed in the upper end of said pedestal.
Beneficial effect of the present invention mainly shows: this valve mechanism is novel, sealability is reliable, can effectively prevent repeated charging; Avoided the spool that other non-refillable valve is easy to generate and valve seat is eccentric, stuck, leak-down rate is high, the anti-low defective of ability that fills once more; Partly be that postwelding is installed and convenient to operation because of its spool again; So be beneficial to the welding operation of valve more, compare other non-refillable valve and can make production process more integrated, improved manufacturing efficiency.
Description of drawings
Fig. 1 is the structural representation of non-refillable cylinder valve.
Fig. 2 is the A-A enlarged view of Fig. 1.
Fig. 3 is the schematic representation of the closed condition of non-refillable cylinder valve.
Embodiment
Below in conjunction with accompanying drawing the present invention is further described.
With reference to Fig. 1～Fig. 3, a kind of cylinder valves for non-refillable cylinder comprises valve rod 1 and valve body 3; Said valve rod 1 is inserted in the said valve body 3, and the side of said valve body 3 is provided with charging air inlet, is provided with the step with said stem lower portion coupling in the valve body below said charging air inlet; Said valve body lower portion is fixedly connected with pedestal 7, and shell fragment 10 is installed on the top of said pedestal 7, places marble 9 on the said shell fragment 10; Said pedestal 7 middle part internal diameters are bigger than said marble, and said pedestal 7 bottom internal diameters are littler than said marble; The lower end of said valve rod 1 be positioned at said marble 9 directly over.
Said valve rod is threaded with valve body, and the joint is provided with seal ring 4.Said pedestal 7 is connected with valve body 3 lower thread.The top installation insurance folder 2 of said valve rod 1.
Place bullet pad 8 on the step between said pedestal middle part and the bottom, block 11 is installed in the upper end of said pedestal 7.
The valve rod 1 of this valve and valve body 3 be through being threaded, and the valve thick stick is packed into behind the valve body valve body upper end reducing, installs safety clip 2 again; Be welded on then on the upper cover of refrigerant cylinder, afterwards 7,8,9,10,11, an one-piece element spool altogether screws in from valve body lower end through screw thread, thereby constitutes a complete cylinder valves for non-refillable cylinder.Marble 9 are clamped by shell fragment 10 when filling first, are got in the container through valve pocket from charging air inlet by the can medium, behind the full medium of can; Take off safety clip, turn the valve thick stick when fastening valve through handle, the valve thick stick is pressed into valve pocket to glass marble; In the time will discharging container inner medium; Turn on the valve thick stick through handle, glass marble leaves the bullet pad under container inner medium pressure, medium is discharged from container; On the contrary, when running into repeated charging, glass marble is compressing on the bullet pad under the effect of external pressure medium, prevents repeated charging thereby close valve seat orifice
Claims (5)
