Description
Technical field
The present invention relates to mechanical structure field, particularly a kind of stepless adjustable mechnical servo switch bleed valve.
Background technique
Because gas turbine is when the operation of low state, the gas compressor state is lower, the bleed underpressure that is used to obturage, so the low state of the gas turbine effect of obturaging is relatively poor, causes the inefficacy of obturaging easily, the lubricating oil leakage.Be head it off, can be through the bleed valve, obturage in that the bleed of gas compressor high pressure stage is auxiliary when realizing the low state of gas turbine, close high-pressure bleed air during high state, gas turbine is normally obturaged.
Because gas turbine bleed temperature is higher, reach usually more than 200 ℃, can't solve through common electromagnetic valve; And the on-off mode of machinery valve is generally the low-pressure valve closing, and the high pressure valve open requires not to be inconsistent with the control of bleed.
Summary of the invention
The objective of the invention is in order to solve gas communication whether control under the high temperature condition, the spy provides a kind of stepless adjustable mechnical servo switch bleed valve.
The invention provides a kind of stepless adjustable mechnical servo switch bleed valve, it is characterized in that: described stepless adjustable mechnical servo switch bleed valve comprises valve bottom 1, valve baffle plate 2, valve top 3; Housing 4, end cap 5, piston 6; Spring 7, Sealing 8, relief opening 9; Pressure regulator 10, clamping bolt 11, lock silk 12;
Wherein: valve bottom 1 is fixedly connected with valve baffle plate 2, and valve baffle plate 2 and valve top 3 are connected through connecting rod, and housing 4 is connected through clamping bolt 11 with end cap 5; Piston 6 is enclosed within the outside at valve top 3; Piston 6 cooperates with housing 4 through Sealing 8, and pressure regulator 10 is installed in end cap 5 middle parts through screw thread, and spring 7 is installed between piston 6 and the pressure regulator 10; Relief opening 9 is positioned at the bottom, side of housing 4, and lock silk 12 is locked on clamping bolt 11 and the pressure regulator 10.
Described pressure regulator 10 is a hollow structure, and the outside is threaded, and extend into housing 4 inner ends and has the shoulder structure.
Described Sealing 8 is a graphite seal.
Through rotary pressure controlling device 10, pressure that can Regulation spring 7 is realized the action of valve baffle plate 2, and then the function that whether circulates of control pressurized gas.
In the accompanying drawing, the direction of arrow indication is that pressurized gas flow to.
Advantage of the present invention:
