Description
Technical field
This utility model relates to valve body field, specifically, being related specifically to a kind of eccentric three butterfly valves.
Background technology
Butterfly valve is again flap valve, is the regulation valve of a kind of simple in construction, simultaneously can be used for the on-off control of low pressure pipeline medium.Its structure is mainly made up of valve body, valve rod, dish plate and sealing ring, and valve body is cylindrical, and axial length is short, built-in dish plate.Its operation principle is: dish plate is driven by valve rod, if turning over 90 °, just can complete once to open and close.Change the deflection angle of dish plate, the flow of medium can be controlled.Its material determines according to purposes and medium, conventional butterfly valve has wafer type butterfly valve and flange form butterfly valve two kinds, wafer type butterfly valve is to be connected between two pipe flanges by valve with stud, flange form butterfly valve is with flange on valve, with bolt by two ends Flange joint on valve on pipe flange.The main seal of butterfly valve is sealing ring, and existing ring structure is complicated, poor sealing performance, installs Maintenance Difficulty, and service life is short.
Utility model content
The purpose of this utility model is for deficiency of the prior art, it is provided that a kind of eccentric three butterfly valves, to solve the problems referred to above.
This utility model is solved the technical problem that to realize by the following technical solutions:
A kind of eccentric three butterfly valves, including valve body, it is provided with end cap in the bottom of described valve body, joint face at described end cap and valve body is provided with pad, described end cap is connected fixing by screw with lid, axial passage is offered in the inside of described valve body, and in described passage, valve rod is installed, it is arranged above valve plate on described valve rod top, at the top of described valve plate, pressing plate is installed, described pressing plate is connected fixing by clamping screw with valve plate, it is provided with sealing ring in the junction of described valve plate and pressing plate, described valve body have an opening above structure, in the outside of described hatch frame, support is installed, in described hatch frame, there is filler, the top of described filler is provided with gland, it is connected fixing at described gland with valve body by stud, on the top of described gland, turbine apparatus is installed, described turbine apparatus connects runner.
Further, the top of described valve plate has projection, and the composition installation position, outside of described projection, described pressing plate is installed on installation position.
Further, the surface at described valve body, end cap, valve rod, gland, turbine apparatus and runner scribbles anticorrosion antiwear layer.
Compared with prior art, the beneficial effects of the utility model are as follows:
By using brand-new structure to design, good seal performance, install and safeguard that simply service life is long.
Accompanying drawing explanation
Fig. 1 is the structural representation of eccentric three butterfly valves described in the utility model.
Label declaration in figure: valve body 1, end cap 2, valve rod 3, valve plate 4, pressing plate 5, support 6, filler 7, gland 8, turbine apparatus 9, runner 10.
