The gate valve is a valve which uses a gate plate as an opening and closing element and realizes the switching on and off of the medium flow by moving along the vertical direction of the center line of the flow channel inside the valve. The gate valve is used for fully opening or fully closing the pipeline, and is not used for regulating the flow. The butterfly valve is also called as flap valve, and is a simple-structure regulating valve, its closing member (valve clack or butterfly plate) is a disk, and can be rotated around valve shaft to implement opening and closing, and can be used for switching control of low-pressure pipeline medium. The butterfly valve is used as a regulating valve, and the butterfly plate is always positioned in the flow channel and can generate resistance to the fluid medium. The more engineering application scenes of the valve are originally, the higher the requirement on the function of the valve is. The composite valve combining the functional advantages of the butterfly valve and the gate valve can adapt to and meet more application sites. A butterfly-gate throttle valve of patent number CN201410216273.X is opened and closed by dislocation of throttle hole and flashboard through hole, and a butterfly valve is arranged on the upper part of throttle plate. A butterfly gate combined valve of CN200420117252.4 is formed by additionally arranging a butterfly valve at the front part of a gate valve pipeline.
Most of currently used valves are single-function valves, and the valves are limited in application occasions and easy to fail under complex working conditions. In the above-mentioned butterfly-gate throttle valve of cn201410216273.X, the provision of a throttle plate in the flow passage causes excessive resistance of the valve. A butterfly gate combination valve of CN200420117252.4 is simply to add a butterfly valve in front of the gate valve pipe.
