Description

A self-filtering ball valve

technical field

The utility model relates to the technical field of ball valves, in particular to a self-filtering ball valve.

Background technique

The existing ball valve has a simple structure and does not have the function of filtering the fluid. Therefore, a ball valve with a filtering function has been developed recently. There are many filter ball valve structures on the market. A branch pipe is opened on the outlet pipe of the ball valve, and a branch pipe is set in the branch pipe. The filter screen, and the branch pipe is blocked with a plug. In this way, the liquid can be filtered by the filter screen, and most of the impurities are deposited on the plug of the branch pipe. When cleaning, the plug needs to be removed and taken out. The filter screen is cleaned, and the disassembly and assembly of the plug brings inconvenience to the operator. On the one hand, the plug is not firmly connected, and water leakage is prone to occur. If the plug connection is too tight, it is difficult to disassemble. On the other hand, the plug is easy to assemble It is dropped and lost in the process. During the sewage cleaning process, the sewage direction cannot be adjusted, which brings inconvenience to the recovery of impurities.

Detailed ways

The following describes in detail the embodiments of the present invention, examples of which are shown in the accompanying drawings, and the embodiments described below by referring to the accompanying drawings are exemplary and are intended to explain the present invention so as to make the present practical The new technical solution is easier to understand and grasp, and cannot be understood as a limitation of the present invention.

Example:

A self-filtering ball valve, as shown in FIGS. 1 and 2, includes a water inlet pipe part 1, a water outlet pipe part 2, a sewage pipe part 3, and a ball valve assembly 4 located on the water inlet pipe part 1 and located on the sewage pipe part 3. The filter screen 5, and the sewage control assembly 6. The water inlet pipe part 1 and the water outlet pipe part 2 are on one axis. The sewage pipe part 3 and the water outlet pipe part 2 form an acute angle, and the range of the acute angle is between 30 degrees and 40 degrees.

The sewage control assembly 6 includes a connecting seat 61 threadedly connected to the port of the sewage pipe portion 3 , a sewage barrel 62 threaded on the inner wall of the connecting seat 61 , a valve core 63 penetrating the sewage barrel 62 to move up and down, and sleeved through a bearing 64 The external connection pipe 65 is outside the sewage drum 62 . The connecting seat 61 can be disassembled, so as to facilitate the removal of the filter screen 5 . A drain hole 621 is provided on the side wall of the drain cylinder 62 . The valve core 63 opens and closes the drain hole 621 by screwing with the drain cylinder 62 . In this solution, generally it is not necessary to take out the filter screen 5 for cleaning. Directly through the impact of the water flow on the filter screen 5 , it is discharged to the outside from the sewage discharge hole 621 on the sewage discharge cylinder 62 .
