Embodiment Construction

[0026] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0027] A butterfly valve structure is provided in the embodiment of the present invention, and the structural diagram is as follows Figure 4 shown, including:

[0028] The valve body 2, the valve 3 and the filter screen, the valve 3 has a quarter-spherical arc surface structure, and the filter screen includes two parts, the first filter screen 11 and the second filter screen 12, both of which have a quarter-spherical arc-surface structure, And adopt the connection mode of the first filter net 11 - the valve 3 - the second filter net 12 to form a valve structure, which is assembled in the valve body 2 .

Abstract

The invention discloses a butterfly valve structure comprising a valve body, a valve, and filter screens. The valve body is in a 1 / 4 spherical chamber structure. The filter screens include a first filter screen and a second filter screen both in 1 / 4 spherical chamber structures, and the first filter screen, the valve and the second filter screen are connected in sequence to form a valve structure fitted in the valve body. The butterfly valve structure is in the valve structure combining the filter screens and the valve; the first and second filter screens are mounted on two sides of the valve body to form the valve structure; when the valve structure closes, gas cannot pass through; when the valve structure opens, the gas passing through is filtered by the first and second filter screens; foreign matters such as glass fragments in the gas can be prevented from entering a mechanical pump through a pipeline; the butterfly valve structure is helpful for checking and replacing the valve and the filter screens and convenient for demounting and maintenance.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a butterfly valve structure for controlling and filtering pipelines. Background technique [0002] Butterfly valve, also known as flap valve, is a regulating valve with simple structure, and it can also be used for switch control of low-pressure pipeline medium. Butterfly valve refers to a valve whose closing part (disc or butterfly plate) is a disc that rotates around the valve shaft to open and close. It mainly plays the role of cutting and throttling on the pipeline. The opening and closing part of the butterfly valve is a disc-shaped butterfly plate that rotates around its own axis in the valve body to achieve the purpose of opening and closing or adjustment. There is also a wafer butterfly valve, the butterfly plate of the wafer butterfly valve is installed in the diameter direction of the pipeline, and the valve is fully open. The wafer butterfly valve has simple structu...
