Background
The butterfly valve is also called a flap valve, is a regulating valve with simple structure, and can be used for on-off control of low-pressure pipeline media. The butterfly valve is a valve in which a closing member (a valve clack or a butterfly plate) is a disk and rotates around a valve shaft to open and close, and mainly plays a role in cutting off and throttling on a pipeline. The butterfly valve opening and closing piece is a disc-shaped butterfly plate and rotates around the axis of the butterfly plate in the valve body, so that the opening and closing or adjusting purpose is achieved. The other type is a wafer butterfly valve, a butterfly plate of which is installed in the diameter direction of the pipeline, and the valve is in a full open state. The opposite clamping butterfly valve has simple structure, small volume and light weight. The butterfly valve has two sealing types of elastic sealing and metal sealing. In addition, the elastic sealing valve is characterized in that the sealing ring can be embedded on the valve body or attached to the periphery of the butterfly plate.
The filter screen is not assembled on the existing butterfly valve, so that foreign matters in the pipeline can easily enter the mechanical pump through the butterfly valve, if the butterfly valve is required to have a filtering function, the filter screen needs to be installed in the front and at the back of the butterfly valve, as shown in figure 1, wherein 2 is a valve body, and 3 is a valve for controlling the pipeline to be opened and closed. By rotating the valve 3 about the valve axis O, opening and closing of the valve is achieved. If the gas is required to be filtered, the filter screens 1 are arranged on the two sides of the outer part of the valve body 2, when the valve 3 is horizontal, the valve 3 is in an open state, as shown in figure 2, the pipelines are communicated, the gas passes through, and the other passing gas is filtered through the filter screens 1 on the two sides of the valve body; when the valve 3 is rotated 90 degrees around the valve shaft and the valve 3 is vertical, the valve 3 is in a closed state, as shown in fig. 3, the pipeline is not communicated, and the gas is blocked by the valve 3 after passing through the filter screen 1 at the front end of the valve body 2.
Therefore, the existing butterfly valve can not realize integration of control and filtration of the pipeline due to the valve body.
