In order to further explain the technical solution of the present invention, the present invention is explained in detail by the following embodiments.
In the description of the present invention, it is to be understood that the terms "center", "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and simplicity of description, and do not indicate or imply that the device or element being referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore, should not be construed as limiting the present invention. In the description of the present invention, "a plurality" means two or more unless otherwise specified.
As shown in fig. 1 to 5, the utility model discloses a two-position three-way solenoid valve with automatic pressure relief function, which comprises a tuyere 1, a coil holder 2, a yoke 3, a valve core 4, a spring 5, a gas plug 6, a gas outlet joint 7, a rear cover 8 and a pressure relief mechanism 9.
The air inlet pipe 11 of the air nozzle 1 protrudes out of the yoke 3 and is connected with an external inflating device (an air pump and the like), one end of the wire frame 2 close to the rear cover 8 is connected with the air outlet joint 7, the air outlet joint 7 can be integrally formed with the wire frame 2 (as shown in each figure), and can also be fixed with the wire frame 2 in a detachable mode. The air outlet joint 7 is provided with an air outlet 71, an air leakage opening 72 and a pressure relief opening 73 which are communicated with the central through hole 21 of the coil holder 2, and the air outlet 71 of the air outlet joint 7 is connected with a product to be inflated (such as an air bag).
The valve core 4, the spring 5 and the air plug 6 are arranged in a central through hole 21 of the wire frame 2, and a sealing ring 12 is arranged between the periphery of the tuyere 1 and the inner wall of the central through hole 21. The case 4 sets up in central through-hole 21 and is relative with tuyere 1 cooperation in the one end of central through-hole 21, and the one end of this case 4 is relative with tuyere 1, the other end with it is relative to give vent to anger joint 7, and the one end that this case 4 and tuyere 1 are adjacent is equipped with the silence gasket 41 of protruding rubber material to reach case 4 terminal surface, and silence gasket 41 can not produce the noise when making case 4 and tuyere 1 contact, the setting of gas plug 6 is at the other end of this case 4 and relative with the mouth 72 that loses heart of giving vent to anger joint 7. A spring 5 is arranged between the valve core 4 and the tuyere 1, and the tuyere 1 and the valve core 4 are pushed outwards by the elastic force of the spring 5, so that the air plug 6 on the valve core 4 blocks the air release opening 72.
As shown in fig. 1 and 2, the pressure relief mechanism 9 includes a pressure relief diaphragm 91, a force receiving ring 93, a pressure relief spring 94 and a bottom cover 95, the one end of the air outlet connector 7 is provided with an air outlet tube 74 with the air outlet 71, the other end of the air outlet connector 7 is provided with a pressure relief cavity 75, the pressure relief port 73 is communicated with the pressure relief cavity 75, a fixing ring is arranged in the pressure relief cavity 75, the pressure relief mechanism 9 is arranged in the pressure relief cavity 75, and the force receiving ring 93 in the pressure relief mechanism 75 is matched with the fixing ring. Be equipped with on the pressure release appearance chamber 75 and communicate pressure release mouth 73 and the gas vent 76 that pressure release appearance chamber 75, the cooperation of pressure release diaphragm 91 of pressure relief mechanism 9 is in the top periphery of atress ring 93, and bottom 95 and pressure release appearance chamber 75 hold the chamber wall together fixed, and bottom 95 and pressure release appearance chamber 75's connected mode can have a variety, as shown in the figure, in this embodiment, be equipped with two at least draw-in grooves 77 on the perisporium that pressure release appearance chamber 75, be equipped with on the bottom 95 and correspond two at least trip 951 of complex with draw-in groove 77. One end of the pressure relief spring 94 abuts against the force-receiving ring 93, and the other end abuts against the bottom cover 95, so that the elastic force of the pressure relief spring 94 blocks the pressure relief opening 73 from the pressure relief diaphragm 91 toward the pressure relief opening 73.
The working principle of the utility model is as follows:
an air inlet pipe 11 of the air nozzle 1 is connected with an air pump, an air outlet 11 of the air outlet joint 7 is connected with a product to be inflated, and when the air is inflated, air enters the central through hole 21 of the wire frame 2 from the air inlet pipe 11 and enters an air outlet 71 of the air outlet joint 7 through the central through hole 21 to inflate the product to be inflated. In the inflation process, if the gas pressure is too large, the gas pressure overcomes the elastic force of the pressure relief spring 94 to push the pressure relief diaphragm 91 and the force receiving ring 93 downward, so that the pressure relief opening 73 is communicated with the pressure relief cavity 75 and the exhaust opening 76, the gas is exhausted from the exhaust opening 76, and when the pressure in the central through hole 21 is smaller than the elastic force of the pressure relief spring 94, the pressure relief spring 94 pushes the pressure relief diaphragm 91 and the force receiving ring 93 upward again to block the pressure relief opening 73.
When air is discharged, after the coil 22 on the periphery of the wire frame 2 is electrified, the valve core 4 overcomes the elasticity of the spring 5 under the action of electromagnetic force, and drives the air nozzle 6 to move towards one end of the air nozzle 1, so that the central through hole 21 of the wire frame 2 is communicated with the air discharge opening 72 of the air discharge joint 7, and the air is discharged from the air discharge opening 72. After air leakage is finished, the coil 22 is powered off, the electromagnetic force disappears, the valve core 4 is abutted against the air outlet joint 7 under the action of the elastic force of the spring 5, and the air plug 6 on the valve core 4 blocks the air leakage opening 72 of the air outlet joint 7.
The utility model discloses take two-position three way solenoid valve of automatic pressure release function will inflate, lose heart and the pressure release function is integrated together, and is small, and need not the circular telegram when aerifing, very big saving energy consumption, compares in prior art, the utility model provides a tradition fill when exhaust system installs, air pump, the problem of a plurality of valve bodies on spatial configuration and pipeline overall arrangement, supply the air current function with the air pump, aerify the function, fill the back and end function, exhaust function etc. and integrate as an organic wholely, the installation volume that significantly reduces not only promotes the convenience of installation by a wide margin, can also make and installation cost very reduce.
The above embodiments and drawings are not intended to limit the form and style of the present invention, and any suitable changes or modifications made by those skilled in the art should not be construed as departing from the scope of the present invention.
