Abstract
The utility model relates to a fast valve, comprising the inner core of a conical valve which is provided with an axial hole and crossed in a radial hole, the outer core of the conical valve whose front end is provided with a filter chamber and back end is provided with a sealing ring and which is used as a valve nozzle, a valve base and a valve body. The utility model is characterized in that when the hose inflating valve (or aerosol can nozzle) of the inner tube for vehicles is punched and poured with fluid, the fluid can be filtered as needed and charged in without leakage, and the process of cloth arrangement between the valve nozzle and the inflating valve is replaced by the sealing ring which can be replaced easily to increase the sealing performance. The utility model has the advantages of convenient operation, reasonable structure, reliable performance, solidness and duration, more than 6 times of energy saving than the similar valve, rapidity, practicability and obvious economical and social benefits.
Description
Belong to the valve class
The utility model relates to a kind of valve.Air compressor gas charging valve especially for the bicycle inner tube inflation.
The utility model improves on similar axle dynamic formula tapered plug gas charging valve.In former valve, valve nozzle is to be made of the hold concurrently pilot hole of valve seat of valve gap.The spool front end is real core or sandwich body, and it is not separately a closed access, and leading edge does not have sealing function spare yet.When spool was subjected to external force inwardly to do axial motion, air chamber was open, and gas is around spool and under the cooperation of valve seat pilot hole, and part charges in the vessel port, and remaining is revealed.So have that air inlet is slow, operation is tired, it is many to leak, a drawback of quick abrasion, pollution weight.
The purpose of this utility model is:
1. design a kind of tapered plug spool that has axial bore to communicate, to change path with radial hole.
2. leak free Fast valve when designing a kind of work that integrates spool, valve nozzle, filter chamber, seal ring is revealed stopping.
The scheme that realizes above-mentioned purpose is:
1. before original tapered plug valve core sealed cover, bore an axial bore, communicate with its hole radially, so that path is changed to valve core inside.
2. on the boss in a valve body (3), adorning valve seat (5), the axis two ends of valve seat (5) are embedded with valve inner core (7) and valve outer core (4), and valve inner core (7) radially has at least one hole (12) axially to communicate at least one hole (6) with it.Valve outer core (4) has an axial bore (16) at least, and its front end is filter chamber (14), and the rear end is valve nozzle (19) and is adorning seal ring (17).Valve inner core (7) intersects in the middle part (13) of valve seat (5) with valve outer core (4).
The utility model has the advantages that: when Fast valve was worked, fluid flowed out valve nozzle by tubulose spool and filter chamber, behind the seal action of seal ring, directly charges in the vessel port, saves the action of shield before valve nozzle.It is quick to have keying, stop to leak, and the characteristics of pollution abatement, and can save energy and reduce the cost more than five times.
Accompanying drawing is a section of structure of the present utility model.
The utility model is described in further detail below in conjunction with accompanying drawing:
After suction tude (10) and source of the gas are connected, vessel port and the utility model are under external force, coincide with valve nozzle (19) seal ring (17) on every side, make valve outer core (4) inwardly do axial motion simultaneously, valve inner core (7) is separated with valve seat (5), make air chamber (11) open, and connect with the inner gateway (16) of spool, outer path (15).At this moment, pressurized air divides the inside and outside two-way of spool outwards to move: interior road, mainly the radial hole (12) by valve inner core (7) enters, through its axial bore (6), again then through the filter chamber (14) of valve outer core (4), enter axial bore (16), under the sealing of seal ring (17), flow out valve nozzle (19); From outside gap (13) and (15) outwards motion of desiring through valve inner core (7) and valve seat (5) and valve outer core (4) and valve seat (5), but, open moment at valve inner core (7), valve outer core (4) is closed with valve seat (5), so from outside (15) are ended, urgent its returns along interior road (16) and charges in the container.Thereby, the gas after valve inner core (7) is opened is charged in the container fully.
Realize best way of the present utility model:
Metalwork of the present utility model only needs engine lathe, drilling machine and electric welding, and its Sealing only need be made the process equipment of General Purpose Rubber spare, can finish manufacturing.It is rational in infrastructure, opens and closes fast, and is easy to manufacture, and reliable in quality is with low cost.Promptly there is manufacturing capacity in the unit that produces existing similar awl (post) plug valve.
Claims (4)
1, Fast valve of being made up of valve seat and spool is characterized in that:
On the boss in a valve body (3), adorning valve seat (5), valve inner core (7) and valve outer core (4) in the axis two ends embedding of valve seat (5), valve inner core (7) radially has at least one hole (12) axially to communicate at least one hole (6) with it.It is filter chamber (14) that valve outer core (4) axially has its front end of at least one hole (16), and the rear end is valve nozzle (19) and seal ring (17).Valve inner core (7) intersects in the middle part (13) of valve seat (5) with valve outer core (4).
2, Fast valve according to claim 1 is characterized in that:
The front end of valve outer core (4) has a filter chamber (14), and the valve nozzle of its rear end (19) external diameter is less than the internal diameter of vessel port.
3, according to claim 1,2 described Fast valves, it is characterized in that:
Valve nozzle (19) outer rim of valve outer core (4) is equipped with seal ring (17).
4, Fast valve according to claim 1 is characterized in that:
Valve inner core (7) is taper, and front end has at least one radial hole (12) to communicate with at least one axial bore (6).
