Problems solved by technology

[0002] The valves on the processing equipment used in the pharmaceutical, biological and food industries currently on the market are all separate valves, but in the processing equipment of these industries it is often found that it is necessary to install multiple valves on the same pipeline at the same time, for example in In the pipeline between the fermentation tank and the refining tank in the pharmaceutical production equipment, it is necessary to install stop valves, throttle valves and diaphragm valves at the same time. It is not only labor-intensive to install these valves on the same pipeline, but also due to the need to control during the production process. It is very troublesome to have too many operating rods, and installing multiple valves at the same time will increase the equipment cost

Abstract

The invention discloses a multifunctional valve, which comprises a valve body, a valve cover, and a valve rod. Wherein, the valve rod is mounted with flaps; the flap comprises a cut-off flap and a taper flap which are connected; the taper flap can flex along the axis relative to the cut-off flap; the material inlet of valve body has a taper surface relative to the taper flap; the inner wall of valve body that near the material inlet has a cut-off flap match surface; when the valve rod compresses down, the taper flap can be matched with taper surface compactly and the cut-off flap can be compactly matched with the cut-off flap matching surface. The invention has the functions of cut-off valve and the throttle valve.

Description

technical field [0001] The invention relates to a valve, in particular to a multifunctional valve used for processing equipment in industries such as medicine, biology and food. Background technique [0002] The valves on the processing equipment used in the pharmaceutical, biological and food industries currently on the market are all separate valves, but in the processing equipment of these industries it is often found that it is necessary to install multiple valves on the same pipeline at the same time, for example in In the pipeline between the fermentation tank and the refining tank in the pharmaceutical production equipment, globe valves, throttle valves and diaphragm valves need to be installed at the same time. Installing these valves separately on the same pipeline is not only time-consuming, but also due to the need to control during the production process. It is very troublesome to have too many operating rods, and installing multiple valves at the same time will ...
