Problems solved by technology

[0002] At present, the butterfly valves used in the pharmaceutical, food, chemical and other industries are single-opening structures. During the material turnover, there are pollution, exposure, oxidation and other phenomena in the working process of the butterfly valves. Since the opening of the butterfly valves is manual operation, the efficiency is low and it is easy to occur. Secondary pollution

Embodiment Construction

[0013] Below in conjunction with accompanying drawing example the invention is further described:

[0014] to combine figure 1 1. The double-open butterfly valve is composed of active valve 1 and passive valve 2. Through the connection of guide post 3 and guide sleeve 4, the double-open butterfly valve can be opened and closed.

[0015] to combine figure 2 , driving shaft 8 and active valve plate 6 are integrated, and the same passive shaft 7 and passive valve plate 5 are also integrated, and the circular rubber sealing ring 9 is installed on the periphery of the active and passive valve plate respectively.

Abstract

The invention relates to a novel butterfly valve, which comprises a drive valve, a driven valve, a guide pin, a guide sleeve, a drive shaft, a driven shaft, a drive valve plate, a driven valve plate and circular rubber sealing rings; and the drive valve and the driven valve are connected through the guide pin and the guide sleeve to make the double-opening butterfly valve realize opening and closing; the drive shaft and the drive valve plate are connected into a whole; likewise, the driven shaft and the driven valve plate are also connected into a whole; and the circular rubber sealing rings are arranged on the peripheries of the drive valve plate and the driven valve plate respectively. The novel butterfly valve has high production efficiency, easy detachment, easy cleaning and no secondary pollution and can realize free opening and closing under a closeness condition.

Description

(1) Technical field [0001] The invention relates to a novel butterfly valve, in particular to a double-opening butterfly valve used in pharmaceutical, food, chemical and other industries. (2) Background technology [0002] At present, the butterfly valves used in the pharmaceutical, food, chemical and other industries are single-opening structures. During the working process of the butterfly valves, there are pollution, exposure, oxidation and other phenomena. Since the opening of the butterfly valves is manual operation, the efficiency is low and it is easy to occur. Secondary pollution. (3) Contents of the invention [0003] The purpose of the present invention is to provide a double-opening butterfly valve with high production efficiency, easy disassembly, easy cleaning and no secondary pollution, that is, the active valve and the passive valve can be freely opened under airtight conditions. Ensure that materials are not contaminated during turnover. [0004] The obje...
