Detailed Description
The present utility model will be described in detail below with reference to the embodiments shown in the drawings, but it should be understood that the embodiments are not limited to the present utility model, and functional, method, or structural equivalents and alternatives according to the embodiments are within the scope of protection of the present utility model by those skilled in the art.
The lower-mounting type double-opening filter element supporting structure shown in fig. 1-6 comprises a flower disc 17, a lower seat ring 1 connected to the flower disc 17, a bearing plate 2 connected to the lower seat ring 1, and nuts 3 connected to the bearing plate 2. Specifically, the lower seat ring 1 and the back of the flower disc 17 are welded with a 2mm weld joint in the circumferential direction, so that the lower seat ring and the flower disc have a fixing function and a sealing function. The nut 3 is fixed on the bearing plate 2 by a circumferential weld joint of 1mm, and finally the bearing plate 2 is put into the lower seat ring 1 and firmly connected by a circumferential weld joint of 2mm. The tension bearing plate 2 is provided with a through hole 20 for the pull rod 4 to pass through.
The sealing plate 7 is also included, the pressure spring seat ring 6 is connected to the sealing plate 7, and the nut 9 is sealed. The sealing plate 7 is a circular plate with the thickness of 4mm, and is connected with the compression spring seat ring 6 by adopting a welding line with the thickness of 3 mm. The compression spring seat ring 6 can tightly press the double-opening filter element 18 under the screwing of the sealing nut 9, and the upper end of the double-opening filter element 18 is tightly abutted against the lower seat ring 1, so that an end sealing effect is achieved.
And also comprises a sealing rubber pad 8 positioned between the sealing nut 9 and the sealing plate 7. After the sealing rubber gasket 8 and the sealing nut 9 are screwed down, the tightness of the end part of the double-opening filter element 18 can be well ensured, and the fluid can completely pass through the double-opening filter element 18.
The novel plastic pulling device is characterized by further comprising a pulling rod 4, wherein a first thread head 41 and a second thread head 42 are respectively arranged at two ends of the pulling rod 4, the length of the first thread head 41 is 12mm, and the length of the second thread head 42 is 32mm. The first thread head 41 passes through the through hole 20 of the tension plate 2 and is in threaded connection with the nut 3, and the second thread head 42 sequentially passes through the compression spring seat ring 6, the through hole 70 of the sealing plate 7 and the sealing nut 9 in threaded connection. The double-opening filter element 18 is sleeved on the pull rod 4, and the double-opening filter element 18 is extruded by the lower seat ring 1 and the pressure spring seat ring 6.
Three fins 5 are uniformly distributed on the circumference of the pull rod 4, and the fins 5 are welded on the pull rod 4 through welding seams of 2mm. The fin 5 mainly guides the insertion of the double-opening cartridge 18 and prevents the double-opening cartridge 18 from being eccentric when installed.
