Detailed Description
The invention is described in detail below with reference to the attached drawing figures:
the fuel filter cartridge with the exhaust valve structure as shown in fig. 1, 2, 3 and 4 comprises a central column 11, a filter medium 14 surrounding the side surface of the central column 11, an upper end cover 12 and a lower end cover 13 positioned at the upper end and the lower end of the central column 11, and the central column 11, the upper end cover 12, the lower end cover 13 and the filter medium 14 are respectively connected and installed into a whole in a hot melting/infrared welding or gluing mode. The upper end cover 12 comprises an annular cover body 121 and a cover body 122 which are integrally formed, the cover body 122 is in a cylindrical rotator shape which is concavely extended from the cover body 121 to the direction of the central column 11, the exhaust valve assembly 2 is installed in the cover body 122, the exhaust valve assembly 2 comprises a shell 21 and a valve core 22, the shell 21 is embedded in the space in the cover body 122, an exhaust cavity 23 is formed by enclosing the shell 21 and the cover body 122, and the valve core 22 is arranged in the shell 21 in a penetrating manner from the inside of the exhaust cavity 23.
In this embodiment, the casing 21 is made of metal with a certain elasticity, and is in a truncated cone shape with a diameter decreasing downwards, and the upper edge of the truncated cone and the cover 122 are connected in a stable nested manner through elasticity, in this embodiment, in order to ensure the stability of installation, the surface of the cover 122 is provided with a ring groove 125, and the edge of the truncated cone is clamped by the ring groove 125 to improve the stability of installation, so that the casing 21 is clamped into the cover 122 to be clamped by the ring groove 125 when the exhaust valve assembly is installed, thereby completing the installation, and being convenient and fast. The bottom of the shell 21 is abutted against the bottom of the cover body 122, the center of the bottom of the shell 21 is raised upwards to form the exhaust cavity 23, and the height of the whole structure of the exhaust valve assembly 2 is reduced due to the reversely raised structure, so that the whole space is saved. The bottom of the cover 122 in this embodiment is further provided with two concentric sealing rings 126 surrounding the exhaust chamber 23, the default height of the sealing rings 126 is slightly higher than the gap between the bottom surface of the housing 21 and the cover 122, so that after installation, the sealing rings are pressed to stop against the bottom surface of the housing 21 to form an effective seal for the exhaust chamber 23.
In this embodiment, the valve core 22 includes a driving portion 221, a connecting portion 222 and a sealing portion 223, which are made of rubber and are integrally formed from top to bottom in sequence, the center of the housing 21 is provided with a connecting hole 211, the connecting portion 222 is cylindrical and is sleeved in the connecting hole 211, the driving portion 221 is located outside the housing 21, and the sealing portion 223 is located in the exhaust cavity 23 and has a diameter larger than that of the connecting hole 211. The seal portion 223 is arcuate in cross section with its arcuate opening directed toward the housing 21. The edge of the connection hole 211 is machined with a number of venting portions 212 in the form of notches. During filtering operation, the fuel oil is filtered inwards through the filter medium 14, solid impurities filtered by the oil entering the central column 111 after filtering are filtered, but gas residues (particularly, a large amount of residual air exists in the installation process when a new filter element is just replaced during vehicle maintenance), because of different densities, the air entering the central column 11 is separated upwards, the oil is led to an internal combustion engine from a pipeline connected with the lower end cover 13 to realize combustion operation, the air is remained in the upper cavity of the central column 11 and the exhaust cavity (23), the air acts on the sealing part 223 to be sealed and attached around the connecting hole 211 under the action of air pressure, when the air needs to be exhausted, the driving part 221 exposed outside the shell 21 is pressed down by a manual or self-contained structure of the filter, so that the exhaust cavity 23 is opened to be communicated with the outside, the air can be discharged from the exhaust part 212 and a gap of the connecting hole 211 to a pressure which does not influence the flow of the fuel oil (namely, the air is equal to or slightly less than the atmosphere), the air is not possible to be released, and the residual air can be prevented from being discharged from the connecting hole 211 under the action of the pressure of the air can be prevented from being splashed under the action of the driving part 221.
In this embodiment, a plurality of vent holes 123 with circular hole structures are machined on the bottom surface of the cover 122 to allow air in the center tube 11 to enter the exhaust chamber 23.
In this embodiment, a metal mesh 24 horizontally disposed in the exhaust cavity 23 is further disposed between the housing 21 and the cover 122, meshes are densely distributed on the surface of the mesh 24, and the mesh 24 is connected to the housing 21 by welding to form a whole, so that the assembly can be conveniently performed as a structural unit during the assembly, meanwhile, the mesh 24 separates the exhaust cavity 23 to a certain extent structurally, and the movement of the valve core 21 along the axial direction of the connecting hole 211 is limited in an effective working range, so that the stability of the operation is ensured, and the valve core cannot fall off. Meanwhile, the dense fine meshes can effectively prevent oil liquid moving upwards under the action of splashing and the like from entering the exhaust cavity 23 to cause oil liquid leakage. On the other hand, the fine structure of the mesh makes the part immersed in the oil play a role in filtering the oil, and further improves the filtering effect.
In this embodiment, six connecting keys 124 are uniformly distributed on the side surface of the cover 122, the center column 11 is in a porous column shape with a plurality of ring bodies 112 circumferentially and circumferentially arranged on six connecting ridges 111 uniformly distributed at intervals, the top ends of the connecting ridges 111 are welded and connected with the connecting keys 124 in a one-to-one correspondence manner, and the point-to-point connection is beneficial to convenient connection, installation and weight reduction.
The above examples are only illustrative of the preferred embodiments of the present invention and are not intended to limit the spirit and scope of the present invention, and various modifications and improvements made by those skilled in the art to the technical solution of the present invention fall within the scope of the present invention, and the technical content claimed by the present invention is fully described in the claims.
