Aiming at the defects in the prior art, the invention aims to provide a novel pressure retaining valve for an air bag damper, which is used for ensuring the stability of air pressure in an air bag.
In order to achieve the purpose, the invention provides the following technical scheme:
The utility model provides a novel pressure retaining valve for gasbag bumper shock absorber, installs on the upper end cover of gasbag, its characterized in that: including the valve body the center of valve body is formed with the runner, the runner with the gasbag intercommunication be formed with the intake duct in the valve body, intake duct one end is in be formed with the interface of admitting air on the preceding terminal surface of valve body, the other end is in be formed with the gas transmission mouth on the inner wall of runner, outside air source passes through the trachea and connects on the interface of admitting air to by intake duct to the interior input gas of runner the gas transmission mouth upper cover is equipped with seal gasket, seal gasket one side will the gas transmission mouth is sealed, and reset spring is being connected to the opposite side still be provided with the gland in the valve body, reset spring one end is connected seal gasket, the other end is connected on the gland.
As the improvement of the invention, a circle of mounting groove is formed in the flow passage, and a precision filter screen and a silencing filter screen are fixed in the mounting groove.
As a further improvement of the invention, a supporting check ring is arranged on the notch cover of the mounting groove and fixes the precision filter screen and the noise reduction filter screen in the mounting groove.
Preferably, a spring guide sleeve is sleeved outside the return spring and fixed on the inner wall of the gland.
As an improvement of the invention, a circle of retainer ring groove is formed on the inner wall of the upper end cover of the air bag, a spring retainer ring is sleeved on the outer wall of the valve body, and the spring retainer ring is clamped in the retainer ring groove.
As a further improvement of the present invention, a circle of sealing groove is further formed on the outer wall of the valve body, an O-ring is fixed in the sealing groove, the O-ring extends outside the sealing groove, and the O-ring is clamped between the inner wall of the upper end cover of the airbag and the sealing groove.
Compared with the prior art, the invention has the advantages that: the pressure retaining valve is added at the air inlet end, so that certain air pressure is always kept in the air bag without frequently starting the vehicle-mounted air pump for inflation, the noise is reduced, the comfort of the product is improved, and the service life of the vehicle-mounted air pump is greatly prolonged.
Drawings
Fig. 1 is a schematic structural view of a pressure retaining valve for a novel airbag shock absorber according to an embodiment of the present invention.
Detailed Description
The pressure retaining valve for the novel airbag shock absorber is further described with reference to the attached drawings.
As shown in the attached drawing, this embodiment is a novel pressure retaining valve for gasbag bumper shock absorber, installs on the upper end cover 1 of gasbag, and this pressure retaining valve is formed with runner 3 including valve body 2 at the central fretwork of valve body, runner and gasbag intercommunication, and gas between the two can circulate each other.
Be formed with intake duct 4 in the valve body, the intake duct includes horizontal section 41 and slash section 42, and horizontal section is formed with air inlet interface 5 on the preceding terminal surface of valve body, is fixing the trachea in air inlet interface, and the intake duct passes through trachea and outside air supply intercommunication, and in this embodiment, outside air supply is the air pump on the car, slash section one end and horizontal section intercommunication, the other end are in be formed with the gas transmission mouth on the inner wall of runner, outside air supply passes through the trachea and to the intake duct gas transmission, again by the intake duct to the interior gas input of runner, be equipped with seal gasket 7 at gas transmission mouth upper cover, seal gasket one side with the gas transmission mouth sealed, reset spring 8 is being connected to the opposite side, still is provided with gland 9 in the valve body, and reset spring one end is connected on. When the air pump is used for conveying air into the air inlet channel, the air pressure provided by the air pump can push the sealing gasket away, so that the air conveying port is opened, the air in the air inlet channel can be conveyed into the flow channel, after the air pump stops supplying air, the air pressure in the air inlet channel disappears, and the sealing gasket is tightly attached to the air conveying port under the action of the air pressure of the flow channel to seal the air conveying port, so that the internal pressure of the flow channel is prevented from being reduced due to the fact that the air is leaked from the air inlet channel, and therefore the function of. In order to prevent the sealing gasket and the return spring from radially deforming in the reciprocating feeding process, a spring guide sleeve 14 is sleeved outside the return spring and fixed on the inner wall of the gland.
The runner is internally provided with a circle of mounting groove, a precision filter screen 11 and a silencing filter screen 12 are fixed in the mounting groove and are respectively used for carrying out dust filtration and silencing filtration on air in the runner, and the silencing filtration is that a layer of silencing cotton is laid on the silencing filter screen. The notch lid of mounting groove is equipped with support retaining ring 13, and support retaining ring passes through fasteners such as screw, pin and fixes outside the notch of mounting groove, and by support retaining ring will precision filter screen and amortization filter screen compress tightly in the mounting groove.
A circle of retainer ring groove 15 is formed in the inner wall of the upper end cover of the air bag, a spring retainer ring 16 is sleeved on the outer wall of the valve body, and the spring retainer ring is clamped in the retainer ring groove. Still seted up the round seal groove on the outer wall of valve body O shape circle 17 is being fixed in the seal groove, O shape circle part extends in the outside of seal groove, O shape circle is held between the upper end cover inner wall of gasbag and the seal groove, and the O shape circle can prevent that the gas in the gasbag from overflowing in the clearance between by pressure retaining valve and the gasbag upper end cover inner wall.
The above description of the preferred embodiments of the present invention is provided to enable those skilled in the art to make various changes and modifications without departing from the spirit of the present invention, and these changes and modifications should be construed as being included in the scope of the present invention.
