Problems solved by technology

[0002] Butterfly valves currently on the market use different medium liquids on both sides of the butterfly valve. When the valve is closed, the two medium liquids stay in the channel due to fusion, or penetrate each other due to seal leakage, causing mutual pollution and secondary pollution.

Embodiment Construction

[0022] The present invention is mainly composed of a butterfly plate 04, two valve bodies 02, 02a, a sealing ring 03, an inlet cleaning pipe 01 and an outlet cleaning pipe 01a, the first bolt 16 fixes the upper device together, and the second bolt 17 connects the upper The device and the connecting body 05 are fixed together, and the two connecting bodies 05 only play the role of connecting pipes in this device. The connecting shaft 07 drives the butterfly plate 04 with the energy from the cylinder 09, and the pneumatic bracket 08 is used to fix the cylinder Figure 1.1-Figure 1.3 . There are arc-shaped grooves on the outer edge of the single butterfly plate 4 of the anti-mixing butterfly valve. R6a connection, so that the butterfly plate itself forms a channel. Once the channel forms a closed condition, it will form a circulation channel, and the cleaning fluid will pass through it for cleaning. Figure 3.1-Figure 3.5 .

Abstract

The invention provides a cleaning type anti-mixing butterfly valve with a single butterfly plate. The cleaning type anti-mixing butterfly valve comprises the butterfly plate, two valve bodies, a sealing ring and an outer cleaning circulating system. Grooves are respectively formed in two peripheral sides of the butterfly plate, adjacent ends of the two grooves are communicated with each other, the other ends of the two grooves are respectively communicated with an inlet cleaning tube and an outlet cleaning tube via first microporous cavities, and the inlet cleaning tube and the outlet cleaning tube are respectively arranged on the two valve bodies and are communicated with the outer cleaning circulating system. The cleaning type anti-mixing butterfly valve has the advantages that residual liquid in a channel can be cleaned, sealing leak liquid also can be cleaned and can be drained from the cleaning circulating channel if leakage occurs, a self-inspection function can be realized, requirements of various driving modes such as a manual driving mode, an electric driving mode and a pneumatic driving mode can be met by driving energy of the butterfly plate, and a driving form of the cleaning type anti-mixing butterfly valve can be interchanged with a conventional butterfly valve driving form.

Description

technical field [0001] The invention relates to a flow control device used for beverage, food, medicine or biotechnology products, in particular to a single disc cleaning type anti-mixing butterfly valve on the flow control device. Background technique [0002] Butterfly valves currently on the market use different medium liquids in the pipelines on both sides of the butterfly valve. When the valve is closed, the two medium liquids stay in the channel due to fusion, or penetrate each other due to seal leakage, causing mutual pollution and secondary pollution. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the present invention provides a single disc cleaning type anti-mixing butterfly valve. The single disc cleaning type anti-mixing butterfly valve of the present invention can not only clean the stagnant liquid in the channel, but also clean the sealing leakage liquid. In the event of leakage, the self-checking function can be realized by d...
