Safety air vavle as described above, wherein, in the valve seat, close to one end of the connection end formed with step surface,
The plunger is arranged between the step surface and the blind end.
Pedestal is attached on airbag, air bag or gas piping by the safety air vavle of the present invention, and gas can enter in pedestal, when
When gas pressure gradually increases, plunger is gradually moved up, and when plunger lower surface moves to more than exhaust outlet, gas is arranged from exhaust outlet
Go out, avoid explosion, when gas pressure reduces, plunger lower surface is pressed back into below exhaust outlet again by spring force, finally
Ensure the air pressure in airbag or air bag in appropriate scope.The device directly uses, and without measuring pressure using pressure gauge, also can
Ensure inflation it is safe and reliable, while avoid plug pressure gauge caused by gas leak.

Embodiment
Embodiments of the invention are described below in detail, the example of the embodiment is shown in the drawings, wherein from beginning to end
Same or similar label represents same or similar element or the element with same or like function.Below with reference to attached
The embodiment of figure description is exemplary, is only used for explaining the present invention, and is not construed as limiting the claims.
The present invention discloses a kind of safety air vavle, and referring to Fig. 1, the air valve includes valve seat 5, plunger 4 and spring 3, and valve body 5 is in cylinder
Shape, one end form blind end, and the other end forms connection end.It is noted that blind end can be that valve body 5 is entered by enclosed construction
Row closure is formed or one end itself of valve body 5 forms closing, i.e., such as cup bottom, blind end and the knot of valve type one
Structure.
The safety air vavle of the present invention is continued with, on the perisporium of valve seat 5, the exhaust outlet 52 formed with insertion perisporium,
Plunger 4, be slideably set in the valve seat 5, spring 3, be arranged in valve seat 5, and positioned at blind end and the plunger it
Between, and the length value of spring 3 in the raw is more than the blind end to the distance value of the exhaust outlet 52.
Connection end is connected with thing to be connected during use, and thing to be connected generally refers to need the article inflated, especially easily
In excessive the product such as air bag, airbag to burst of inflation.For convenience of explanation, the present invention is said by taking air bag as an example below
It is bright, but it is noted that this is not limited to the application.
Connection end is connected with air bag, in inflation, gas can also enter valve seat 5, and with the progress of inflation, air pressure increases,
Scope is limited when air pressure exceedes, plunger 4 can be jacked up by air pressure, it is exceeded exhaust outlet 52, and the gas in air bag is from exhaust outlet 52
Release, avoid explosion, and air pressure reduces hand, plunger 4 resets in the presence of spring 3, blocks exhaust outlet 52, air bag when final
Interior air pressure meets requirement, realizes the control to air pressure in air bag.According to the requirement of different air pressure, different elasticity systems can be selected
Several springs.
Connection end has external screw thread, can be threadingly attached to air bag connection, naturally it is also possible to be that connection end is glued with air bag
Connect.In order to ensure air-tightness, an at least loop pillar plug sealing ring 41 is also arranged with outside the plunger 4.
In further valve seat 5, as shown in Fig. 2 close to one end of the connection end formed with step surface 54, the plunger 4
It is arranged between the step surface 54 and the blind end.Ensure that plunger 4 will not come off from valve seat 5, improve safety air vavle
Reliability.
Illustrate the structure of blind end below, according to form, blind end can be divided into integral type and split type.
Integral type is that valve seat 5 is structure as a whole with its blind end, it is not necessary to extra plugging structure.
The blind end of split type i.e. valve seat 5 is formed by plugging structure, such as in one embodiment, blind end is by end cap
1 is formed, and end cap 1 is threadedly coupled with the valve seat 5.End cap 1 includes lid 12 and connector 11, and the connector 11 is from the lid
Body 12 stretches out, and has external screw thread on the connector 11；The junction of the valve seat 5 and the end cap 1 is formed with interior spiral shell
Line 56, and on the end face that the valve seat 5 is connected with the end cap 1, formed with annular groove 51, in annular groove 51
It is provided with end cap seal circle 2.Preferably, the internal diameter of end cap seal circle 2 is less than or equal to the external diameter of the connector 11.
Air-tightness can preferably be ensured using the valve seat 5 of integral type, and use split type valve seat 5 can easily more
Plunger 4 and spring 3 are changed, especially changes spring 3, according to different air pressure requirements, different springs can be selected, so that this
The safety air vavle of invention can be by wider array of applicability.
Construction, feature and the action effect of the present invention, above institute is described in detail according to the embodiment shown in schema above
Only presently preferred embodiments of the present invention is stated, but the present invention is not to limit practical range shown in drawing, it is every according to structure of the invention
