Abstract
The utility model relates to a kind of oil tank leakproof antispray liquid feed valve, comprise the valve body being fixed on oil tank import department and the spool being placed in valve body, valve body is offered liquid entering hole, liquid outlet and valve core piston moving conduit, spool is provided with valve rod, valve rod is inserted in valve core piston moving conduit, stem exterior is socketed with holddown spring, and spool is pressed together on the liquid entering hole of described housing under the cooperation of holddown spring, is provided with baffle plate at liquid outlet; Reveal when when this valve can prevent oil tank oil-feed, fluid splash or input duct are broken.
Description
Technical field
The utility model relates to a kind of liquid feed valve, and especially a kind of oil tank leakproof antispray liquid feed valve, belongs to technical field of valve manufacturing.
Background technique
Along with the high speed development of logistics, warehousing and transportation facilities plays increasing effect in logistic industry.Particularly large-scale can-type storage equipment, can store and transport liquid, and with it, feature accounting in warehousing and transportation facilities such as economic, clean, safe, convenient and easy care is heavy increasing.
No matter fixing or portable storage, fortune oil vessel, as storage tank, oil truck etc., all may there is breakage or leakage in its charge of oil pipeline, if internal tank does not have leakage-preventing measure, spilling of great amount of fuel oil just may cause serious accident.
When toward in oil tank during oiling, what oil pressure can be suitable is large, if prevent its splash without measure, can produce a large amount of electrostatic accumulation, there is great potential safety hazard.If prevent its splash without measure, Oil shocking container wall can produce much noise; Also out, accident may be caused from the manhole at top (or peep hole) splash.
Model utility content
The purpose of this utility model is: for above-mentioned prior art Problems existing, can prevent the leakproof antispray liquid feed valve of fluid splash or leakage when proposing a kind of oil tank oil-feed.
In order to reach above object, the oil tank leakproof antispray liquid feed valve that the utility model provides, comprise the valve body being fixed on oil tank import department and the spool being placed in valve body, valve body is offered liquid entering hole, liquid outlet and valve core piston moving conduit, spool is provided with valve rod, valve rod is inserted in valve core piston moving conduit, stem exterior is socketed with holddown spring, spool is pressed together on the liquid entering hole of described valve body under the cooperation of holddown spring, when outside oil pressure exceedes the elasticity oppressive force of holddown spring, spool is by fluid jack-up, and fluid enters oil tank through valve body; Be provided with baffle plate at liquid outlet, the object of baffle plate is the splash of oil when stoping charge of oil.
Preferred version of the present utility model is:
Further, valve body comprises the valve seat and valve gap that are coupled to each other, valve seat is fixed on oil tank import, the middle part of valve seat is provided with the liquid entering hole matched with oil tank import, the sidewall of valve gap is provided with liquid outlet, and the center of top of valve gap has valve core piston moving conduit, and holddown spring is socketed in valve core piston moving conduit and stem exterior, and the two ends of holddown spring withstand on inside piston head and valve gap respectively, and baffle plate is fixed on the top of valve gap.
Further, the place that baffle plate is matching with valve core piston moving conduit is reserved with through hole, and baffle plate stretches out and covers above described liquid outlet side.
Further, spool contacts with liquid entering hole to be formed and seals.
The utility model beneficial effect is: the utility model structural safety is reliable, effectively can prevent the splash produced during oiling, and when preventing charge of oil pipe damaged, in container, oil plant spills, and ensures the safety of petroleum storage and transportation.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is further described:
Fig. 1 is sectional structure schematic diagram of the present utility model.
Fig. 2 is using state reference drawing of the present utility model.
