The utility model provides a rubber oil fence charging and aspirating valve which is applied to charging and aspirating in a sealed gas cell. The rubber oil fence charging and aspirating valve is characterized by mainly comprising a valve seat, a gland bush and a valve cover and is characterized in that the valve seat has a shape of a frustum and is provided with a central hole; an inner lug is arranged on the central hole wall of the valve seat; the upper part of the valve cover is provided with an annular flat clamp; an outer lug is arranged on the outer wall of a cylinder body at the lower end of the valve cover; the lower end of the valve cover is arranged inside the central hole of the valve seat; the center of the valve cover is provided with a concave dead wrench hole; the inner lug of the valve seat has two symmetrical parts, the lower plane of the inner lug has a grade of slope; the outer lug of the valve cover has two symmetrical parts, the upper plane of the outer lug has a grade of slope; the outer lug of the valve cover is positioned at the lower part of the inner lug of the valve seat, and the valve cover is rotated to tightly press the gland bush. The rubber oil fence charging and aspirating valve has the advantages of simple structure, small volume, reliable sealing, simple and convenient gas charging and aspirating operations, and easy processing and manufacture. The rubber oil fence charging and aspirating valve overcomes the shortcomings of the prior gas charging valve that the structure is complicated, the sealing is not reliable and sundries are left at the air inlet.

Description

Rubber oil boom fills Aspirating valves

Technical field

The utility model relates to a kind of Aspirating valves that fills that sealed gas chamber fills exhaust that is used for.

Background technique

The existing gas charging valve that is used for sealed gas chamber is of a great variety, is CN1584381Y as the Chinese patent notification number, discloses the gas charging valve assembly parts of a kind of liner plate or goods airbag, has defectives such as complex structure, volume be bigger.The Chinese patent notification number is CN200996494Y, and a kind of gas charging valve that discloses can be finished the exhaust of filling of sealed gas chamber, and relatively simple for structure, effect is relatively good.But some foreign material may enter and remain in suction port peripheral groove place in the using process, as silt or organism in water etc.Have a strong impact on the sealing of gas charging valve when inflating next time.

The model utility content

The purpose of this utility model provides a kind of rubber oil boom and fills Aspirating valves, reach fill Aspirating valves sealing reliable, fill exhaust and convenient, simple in structure, volume is little, overcome existing gas charging valve and exist complex structure, the insecure deficiency of sealing and foreign material can remain in the deficiency at suction port peripheral groove place.

The technical solution adopted in the utility model is: rubber oil boom fills Aspirating valves and mainly is made up of valve seat, sealing gasket and valve gap, it is characterized in that: valve seat is a truncated cone, valve seat has center hole, on the valve base center hole wall inward flange is arranged, the annular flat pressing plate is arranged at valve gap top, valve gap lower end cylindrical body outer wall has outward flange, and the valve gap lower end is in valve base center hole.There is the obstructed driving hole of depression at the valve gap center.The inward flange of valve seat is a two parts symmetrical, and the lower plane of inward flange is gradient; The outward flange of valve gap is a two parts symmetrical, and the last plane of outward flange is gradient.The valve gap outward flange rotates valve gap in the bottom of the inward flange of valve seat, and valve gap can the compression seal pad.

The inward flange lower plane gradient of described valve seat is 1: 20; On the outward flange of described valve gap the plane gradient be 1: 20.

For making sealing more between valve gap and the air valve seat, described sealing gasket has annular groove on the plane.The quantity of annular groove is 2-5.

Outer surface at valve seat can vulcanize one deck rubber, can improve sealability, and more attractive and durable.

The beneficial effects of the utility model are: rubber oil boom fill Aspirating valves have simple in structure, volume is little, sealing is reliable, fill air absorbing body manufacturing easy and simple to handle, easy.Overcoming existing gas charging valve exists complex structure, the insecure deficiency of sealing and foreign material can remain in the deficiency at suction port peripheral groove place.

Embodiment

Embodiment 1: with a diameter is that the air valve seat that 200 millimeters rubber oil boom fills Aspirating valves is that example describes.Consult Fig. 4, Fig. 5.Valve seat 3 is a truncated cone, and the bottom surface diameter of valve seat 3 is 200 millimeters, highly is 10 millimeters, and last planar diameter is 80 millimeters.Truncated cone valve seat 3 has center hole 6, and symmetry has 2 inward flanges 7 on valve base center hole 6 walls, and the inward flange 7 lower plane gradients of valve seat 3 are 1: 20.Vulcanize the rubber of one deck 1 millimeters thick at the outer surface of valve seat 3.

Consult Fig. 6.The annular flat pressing plate is arranged at valve gap 1 top, and valve gap 1 lower end cylindrical body outer wall has the outward flange 8 of 2 symmetries, on the outward flange 8 of valve gap 1 plane gradient be 1: 20.There is the obstructed driving hole 9 of depression at valve gap 1 center.

Consult Fig. 1, Fig. 2.The high-intensity waterproof binding agent of valve seat 3 usefulness is bonded on the air chamber wall 4.Valve gap 1 lower end is in valve base center hole 6.Valve gap 1 outward flange 8 rotates valve gap 1 in the bottom of the inward flange 7 of valve seat 3, and valve gap 1 can compression seal pad 2.

Consult Fig. 3.Sealing gasket has annular groove 5 on 2 planes.The quantity of annular groove 5 is 4.

The working principle that summary the utility model rubber oil boom fills Aspirating valves helps understanding the utility model.Consult Fig. 1.Valve seat 3 is bonded on the air chamber wall 4; Cut out arc incision on air chamber wall 4, form a ligulate flap, otch becomes filling channel.Valve gap 1 is installed in valve seat 3 tops, and sealing gasket 2 is installed between the two.During inflation, the valve gap 1 of outwarding winding is pressed on special-purpose pneumatic head sealing surface on the last rubber surface of valve seat 3.Under the effect of air pressure, air-flow is with the direction of ligulate flap top to the air chamber inboard, and gas charges into air chamber by arc incision.Behind the air chamber gassy, remove pneumatic head, under the effect of air pressure and air chamber wall spring-back force, the ligulate flap is close on the rubber surface of air valve seat assembly bottom, makes gas charging valve form sealing just.Screw valve gap 1 again, promptly revolve and turn 90 degrees, allow sealing gasket 2 be under pressure, make gas charging valve obtain secondary seal.When air-breathing, the valve gap 1 of outwarding winding is pressed on special-purpose pneumatic head sealing surface on the last rubber surface of valve seat 3.The pneumatic head push rod backs down the ligulate flap, and the gas in the air chamber fills Aspirating valves by sucking-off rapidly by arc incision and rubber oil boom.
