Embodiment Construction
[0020] In order to better understand the present invention, the present invention will be further described below in conjunction with specific embodiments and accompanying drawings.
[0021] Such as Figure 1-2 Shown, a kind of preparation method of the valve with fine filter function, comprises valve body 3, and described valve body 3 is provided with the bushing 5 that is used for wearing and tearing, and described bushing 5 is provided with valve core 6, and described A valve stem 1 is arranged inside the valve body 3, and the bottom end of the valve stem 1 is connected with a fastener 4 to prevent the valve stem 1 from slipping out of the valve body 3, and the valve stem 1 passes through the valve body 3 is fixedly connected with the valve core 6. Both end surfaces of the valve body 3 are fixed with connecting pieces 2 for fixing the valve body 3 in the fluid delivery pipeline.
[0022] The spool 6 includes an installation frame, and filter screens can be detachably conn...

The invention provides a method for preparing a valve with fine filtering function, which includes a valve body, a bushing for anti-wear is arranged in the valve body, a valve core is arranged in the bushing, a valve stem is arranged in the valve body, and the bottom end of the valve stem is connected to There are fasteners to prevent the valve stem from slipping out of the valve body. The valve stem passes through the valve body and is fixedly connected with the valve core. Both end surfaces of the valve body are fixed with connecting pieces for fixing the valve body in the fluid delivery pipeline ;The spool includes a mounting frame, and both sides of the mounting frame can be detachably connected with filter screens. The filter screen that the fluid passes through first is the first filter screen, and the filter screen that the fluid passes through is the second filter screen. The aperture is larger than the aperture of the second filter screen. The beneficial effects of the present invention are: the design enables the first filter screen to have a coarse filter function, and the second filter screen has a fine filter function; this design will neither seriously reduce the water flow velocity in the pipeline, but also make the water flow obtain a certain degree of purification.
Description
technical field [0001] The invention relates to the technical field of valves, in particular to a method for preparing a valve with fine filtering function. Background technique [0002] In the fluid delivery process, the valve is one of the important components to control the fluid delivery state. Generally speaking, the valve has the function of shutting off and regulating the flow rate. These functions are suitable for fluids with higher cleanliness. When transporting fluid with impurities, such as water containing suspended solids or suspended small particles of pollutants, impurities may randomly stay on the inner wall of the pipe. If things go on like this, the internal diameter of the pipeline will be narrow. This can easily cause blockage of the pipes, resulting in the failure of normal water delivery. Of course, at this time, the purpose of removing clogging can be achieved by cleaning the pipeline. However, pipeline cleaning is time-consuming and laborious, wh...
