进口气动多通偏心蝶阀美国阿卡迪亚品牌

进口气动多通偏心蝶阀Product Description:

It includes a butterfly valve body, a three-way pipe and a sliding connection type transmission device. Two interfaces horizontally connected in the three-way pipe are respectively connected with a butterfly valve body. The sliding connection type transmission device comprises a fixed transmission assembly, a press type positioning device and a movable connector. The two groups of fixed transmission assemblies are symmetrically arranged on the corresponding butterfly valve body in a mirror image; Each set of fixed transmission components includes a reversing device and a fixed guide rotating cylinder. The fixed guide rotating cylinder is connected with the valve rod through the reversing device. The movement of the pushing device can drive the projection in the pressing plate to be inserted into the through hole of the guide rotating cylinder. The end of the movable connecting piece is provided with an elastic piece corresponding to the through hole one by one, and the end of the elastic piece can protrude out of the corresponding through hole; The pneumatic device is used to drive the movable connector to rotate. The utility model has the advantages that each valve body can be adjusted independently and two valve bodies can be adjusted in linkage.

进口气动多通偏心蝶阀characteristic:

Butterfly valve, also known as flap valve, is a regulating valve, which can be used for switching control of low-pressure pipeline medium. Butterfly valves are divided into electric butterfly valve, pneumatic butterfly valve, hydraulic butterfly valve and manual butterfly valve according to the driving mode, and are divided into central sealing butterfly valve, single eccentric sealing butterfly valve, double eccentric sealing butterfly valve and triple eccentric sealing butterfly valve according to the structural form.

进口气动多通偏心蝶阀Principle:

The optimization of equipment structure has not brought about outstanding improvement effect. The three-way butterfly valve is hinged with the valve stems of the two butterfly valves through the connecting rod, and the two valve discs are driven to rotate correspondingly through the rotation of the connecting rod, so as to realize the closing of the two water outlets and the flow control. The technical scheme has the following technical defects: the hinge mode can realize the technical effect of one valve flap opening, the other valve flap closing, or two valve flaps opening at a certain angle at the same time, but it can not realize the independent targeted control of one valve flap, that is, the flexibility of linkage in the technical mode needs to be improved; In addition, in order to meet the sealing property of the valve, a number of sealing structures are provided at the connection between the valve stem and the valve body, which leads to a large rotation resistance of the valve stem. However, the hinged transmission mode acts on the valve technical field, and the torsion of the connecting rod acts on the valve stem, which easily causes the technical problem of relative sliding and affects the normal operation of the valve. The three-way butterfly valve with soft seal on the center line is realized by setting a valve disc diagonally on the pipe body. Because the valve stem in this technical scheme must be set in the center, the eccentric setting of the butterfly valve cannot be realized, and it is difficult to meet the requirements of sealing and disc movement.
