Detailed Description
The following describes in further detail the embodiments of the present invention with reference to the drawings and examples. The following examples are illustrative of the invention but are not intended to limit the scope of the invention.
As described above, the structure of the refueling limit valve for use in the fuel tank according to the embodiment of the present invention includes, as shown in fig. 1 to 3: the flange cover 1, the upper shell 2, the sealing piece 3, the sealing support 4, the valve core 5, the spring 6 and the lower shell 7;
the sealing piece 3 is fixed with the sealing bracket 4;
The sealing support 4 is fixed with the valve core 5;
The spring 6 is arranged between the valve core 5 and the lower shell 7, and the spring 6 can push the valve core 5 to enable the valve core 5 to push the sealing support 4 upwards, so that the sealing piece 3 props against the upper shell 2 to play a sealing role;
the upper shell 2 is embedded into the lower shell 7, and the sealing sheet 3, the sealing support 4 and the valve core 5 are sleeved in the upper shell 2;
the flange cover 1 and the lower housing 7 are buckled with each other.
The flange cover 1 is provided with a buckle 11; the lower shell 7 is provided with a clamping groove 71;
the flange cover 1 and the lower case 7 are engaged with each other by the buckle 11 and the groove 71.
The flange cover 1 is provided with a lower shell bulge 12, and an upper shell positioning groove 13 is arranged on the lower shell bulge 12;
the upper shell 2 is provided with a flange cover bulge 21;
when the upper shell 2 is installed, the flange cover bulge 21 is inserted into the upper shell positioning groove 13, so that the installation position of the upper shell 2 on the flange cover 1 is accurately positioned;
the lower shell 7 is provided with a flange cover groove 72;
when the lower case 7 is mounted, the lower case protrusion 12 is inserted into the flange cover groove 72, and the fixing position between the flange cover 1 and the lower case 7 is accurately positioned.
The bottom of the lower shell 7 is outlined by an elastic buffer sheet 73 through a linear cutting groove, and the right angle turning at the front end of the elastic buffer sheet 73 is outlined by a transverse block 74 perpendicular to the elastic buffer sheet 73; the elastic buffer 73 is fixed to the lateral block 74.
The lateral block 74 is provided with a lateral block protrusion 75, and the upper case 2 is placed on the lateral block protrusion 75 and is buffered against the up-and-down floating of the upper case 2 by the elastic force of the elastic buffer piece 73.
The bottom of the lower housing 7 is provided with a buffer plate 76.
The buffer plate 76 includes a first buffer sheet 761 and a second buffer sheet 762;
The first buffer tab 761 is fixedly connected with the second buffer tab 762 through a first leg; and the first leg divides the first oil passage between the first buffer plate 761 and the second buffer plate 762,
The second buffer piece 762 is fixedly connected with the bottom of the lower shell 7 through a second support leg; and the second leg partitions a second oil passage between the second buffer 762 and the lower case 7;
When the oil level in the oil tank reaches a certain height, oil flows into the lower shell 7 from the first oil duct and the second oil duct, the oil in the lower shell 7 generates buoyancy to the valve core 5, and the buoyancy pushes the valve core 5 to rise under the action of the spring 6; the oil level continuously rises, and the rising height of the valve core 5 also continuously increases until the valve core 5 pushes the sealing support 4 to rise so as to block the channel of the upper shell 2 by the sealing sheet 3, and oil cannot overflow from the pressure relief opening of the flange cover 1 through the upper shell 2;
When the oil level in the oil tank drops, the valve core 5 loses buoyancy of oil, the spring 6 cannot support the weight of the valve core, the valve core 5 starts to drop, the sealing support 4 and the sealing piece 3 also drop together, the upper shell 2 is not in a blocking state, air outside the oil tank enters the upper shell 2 from the pressure relief opening of the flange cover 1, and therefore the air enters the oil tank, and pressure balance in the oil tank is maintained.
In order to ensure the tightness of the joint of the upper shell 2 and the flange cover 1 and prevent gas in the oil tank from leaking from elsewhere, a first circular sealing ring 22 is sleeved at the end part of the upper shell 2.
Meanwhile, a second round sealing ring 14 is sleeved at the pressure relief opening of the flange cover 1, so that the tightness of connection of the pressure relief opening of the flange cover 1 with other equipment is ensured.
The foregoing is merely a preferred embodiment of the present invention, and it should be noted that it will be apparent to those skilled in the art that modifications and variations can be made without departing from the technical principles of the present invention, and these modifications and variations should also be regarded as the scope of the invention.
