Multifunctional valve

Abstract

The multifunctional valve includes valve body, valve cover and valve rod, and on the valve rod, there are valve clacks including cut-off valve clack and conic valve clack connected mutually with the cut-off valve clack. The valve body has a conic surface in the material inlet corresponding to the conic valve clack, a cut-off valve clack matching surface on the inner wall near the material inlet, and a sealing pad made of elastic anticorrosive material in the cut-off valve clack corresponding surface. When the valve rod is depressed downwards, the sealing pad matches first with the cut-off valve clack matching surface and the conic valve clack matches then with the conic surface. Therefore, the multifunctional valve possesses the functions of both cut-off valve and 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. In addition, installing multiple valves at the same t...

[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. In addition, installing multiple valves at the same time will increase the equipment cost, and if one of the above-mentioned valves leaks in the use of pharmaceutical production equipment, it will bring unnecessary trouble to the entire pharmaceutical production system, and will cause serious problems. Change the material, cause bacterial contamination, and in serious cases, vicious backflow will occur, which will bring huge economic losses to the enterprise
