Abstract
The utility model relates to a two-way air-mould valve, which is used for inflating and venting air for various air-mould products. The two-way air-mould valve is composed of an outer valve body and an inner valve body arranged in the outer valve body, wherein the bottom surface of the outer valve body is provided with a plurality of circular valve openings and the inner valve body is integrally erected on the middle part of the bottom surface of the outer valve body. The outside of the lower end of the inner valve body is provided with a soft plastic rubber sealing piece which is tightly attached to the lower surface of the bottom surface of the outer valve body to cover and seal the circular valve openings. A valve opening of the inner valve body is matched and connected with a sealing plug thereof, and the upper surface of the sealing plug is connected with a fixed piece with holes via a pressure spring. The fixed piece is matched and connected with the inner surface of an empty cavity of the inner valve body through screw threads, and the upper port of an empty cavity of the outer valve body is matched with a dustproof cover with a plurality of fine holes through the screw threads. The outer valve body is sealed with a corresponding valve seat through a sealing ring in an annular groove. The utility model has the advantages of adaptation to requirements of air ventilization in different pressures, easy and quick air inflation and good sealing effect.
Description
Affiliated technical field
The utility model relates to a kind of two-way air model valve, is applied to the gas that charges and discharge of various gas mould products.
Background technique
The aerial dance star that the lift-off balloon of riot of color, rainbow arched door, column, China mount, dance lightly, large-scale entertainment for children city, various tents, cartoon mascot; Inflatable products such as track and field obstacle, recreational facilities, gas mould carwash pond all need to utilize the blower fan inflation.Need with confined gas wherein after charging gas, the preservation product also needs gas is bled off for convenience.Charge and discharge gas for convenience, existingly used a kind of air valve, it cooperates use to be installed in jointly on this series products with valve seat.The valve body of described air valve is one and is with externally threaded straight-through tube, and is matched with the internal thread of valve seat through-hole.There is a dull and stereotyped annulus in the valve seat through-hole outside, is used for sticking with glue agent around the inflatable product wall circular hole superimposed.So when valve seat was fixed on the inflatable product, the valve body straight-through tube just was spun in the through hole of valve seat, the inner chamber of straight-through tube has just become the necessary channel that charges and discharges gas.For institute inflation body can be kept in the product, valve body is also joined a valve gap with pipe close effect.When being covered with regard to plug on straight-through tube and with confined gas, the body of inflating spills into the external world through the straight-through tube cavity during dial-out.The shortcoming of this kind structure has two: one, because the variation of ambient temperature may be enclosed in overvoltage gas in the gas mould for a long time, causes the damage to the gas mould; The 2nd, a large amount of escape of gas are arranged to extraneous when transfering to top capping inflation body, very inconvenient.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, the two-way air model valve that provide a kind of and can not be enclosed in overvoltage gas in the gas mould for a long time, make-up gas does not have escape.
The purpose of this utility model can reach like this: a kind of two-way air model valve, to form by valve body and by the matched valve seat of internal and external threads, and this valve seat has the link with the matched sealing of gas mould product sidewall circular hole; It is characterized in that valve body is made up of outer valve and inner inner valve body thereof; The outer valve bottom surface has some round valves doorway, and bottom surface central authorities insert integratedly and founding inner valve body, and a soft rubber diaphragm seal of moulding is with in the outside, inner valve body lower end, and it is close to outer valve bottom surface lower surface numerous round valves doorway is covered with sealing; The inner valve body valve port is matched with its sealing plug, and the sealing plug upper surface links to each other with fixed plate with holes by stage clip, and fixed plate is matched with inner valve body cavity internal surface by screw thread.
Above-mentioned a kind of two-way air model valve is characterized in that outer valve inner cavity upper end-hole joins dust cover with numerous pores by screw thread; Outer valve seals with its corresponding valve seat mutually by the seal ring in the ring groove.
The utility model has following advantage compared to existing technology:
1,, can adapt to exhaust needs under the different pressures by the extending amount of regulating stage clip according to different product;
2, tonifying Qi is easy fast;
3, easy for installation, only need to use to get final product with its valve seat that matches sealing;
4, good seal performance.
Description of drawings
Accompanying drawing is the utility model structural representation
Seal ring 3 among the figure between 1 valve seat valve body is that outer valve 5 is that dust cover 7 is that dust cover pore 8 is that through hole 9 on the fixed plate is that fixed plate 11 is that stage clip 13 is that sealing plug 15 is the soft valve ports that rubber diaphragm seal 17 is outer valves of moulding
Embodiment
The utility model is further described below in conjunction with accompanying drawing.
A kind of two-way air model valve, the built-in seal ring (1) that together is installed in the matched sealing of respective valve seat on the gas mould product sidewall of its outer valve (3) annular groove.Outer valve (3) is matched with screw thread with the through hole of corresponding valve seat.Outer valve (3) bottom surface has some round valves doorway (17), and they closely are covered with by the soft rubber diaphragm seal (15) of moulding that relies on self elastic force to be fixed on the outside, inner valve body lower end.Inner valve body is inserted in the inner bottom surface central authorities of outer valve (3) integratedly; The valve port plug of inner valve body sealing plug (13), and a word fixed plate (9) of band through hole (8) is spun in the inner valve body cavity, and stage clip (11) one ends are against sealing plug (13) upper surface, and a upright end is against the lower surface of fixed plate (9).Dust cover (5) is spun on outer valve (3) cavity upper end-hole, and it has some pores (7).
Drive dust cover (5) with hand-screw, but this moment make-up gas.The soft rubber diaphragm seal (15) of moulding is pressed by extraneous inflation and is opened, the body of inflating enter gas mould product inside by the valve port on the bottom surface (17).Inflation finishes, and the soft rubber diaphragm seal (15) of moulding tightly is covered with valve port (17) and prevents that escape of gas in the gas mould product is to extraneous.When pressure that the gas pressure in the gas mould product sets greater than corresponding stage clip (11), sealing plug (13) is motion outwards, and the valve port of inner valve body is opened, gas through the pore (7) on through hole (8), the dust cover (5) to extraneous; When external and internal pressure was in a basic balance, it is airtight that sealing plug (13) is subjected to stage clip (11) effect to fall original position after rise, finishes the release to excess pressure.So the utlity model has the internal pressure too high functions such as release of pressure regulation to adapt to different gas mould products, tonifying Qi and to raise and cause because of external temperature.
