[0010] Preferably, a spring is provided at the upper end of the flange, the spring supports the filter pressure plate, and the filter pressure plate enters the filter; the filter is clamped by the filter pressure plate to make the filter more fully filtered, and the support of the filter pressure plate by the spring can adapt to the length of the filter.

[0011] Preferably, a metal hoop is provided at the lower end of the filter screen, and the bottom end of the filter screen passes through the circular inlay in the middle of the card. The card slot is T-shaped, and is welded with a disc and a ring; it plays a role in fixing and limiting the filter screen.

[0012] Compared with the prior art, the utility model has the following beneficial effects: a spring is arranged between the filter valve cover and the filter, and above the spring is a filter pressure plate which plays a fixing role. The spring supports the flange, one side of the filter is connected to the filter pressure plate, and one end is fixed on the card. When the filter needs to be replaced, the flange is directly unscrewed, the spring and the filter pressure plate are removed, and the filter can be directly replaced. The filter can be used in various lengths and specifications. Because the spring is retractable, the problem of difficult replacement of the filter in the past is solved. This method is easy to assemble and disassemble, which greatly improves work efficiency. BRIEF DESCRIPTION OF THE DRAWINGS
