Abstract
A kind of stepless adjustable mechanical servo switch bleed valve, is characterized in that: described stepless adjustable mechanical servo switch bleed valve comprises bottom valve, valve baffle plate, valve top, housing, end cap, piston, spring, Sealing, relief opening, pressure regulator, clamping bolt, lock silk; Wherein: be fixedly connected with valve baffle plate bottom valve, valve baffle plate is connected by connecting rod with valve top, housing is connected by clamping bolt with end cap, piston sleeve is in the outside at valve top, piston is coordinated with housing by Sealing, and pressure regulator is arranged in the middle part of end cap by screw thread, and spring fitting is between piston and pressure regulator, relief opening is positioned at the side lower of housing, and locking wire lock is tightly on clamping bolt and pressure regulator.Advantage of the present invention: the automatic cut-out solving the bleed of obturaging of the low state of gas turbine and high state, on the gas turbine that can be widely used in similar demand or equipment.
Description
Technical field
The present invention relates to mechanical structure field, particularly a kind of stepless adjustable mechanical servo switch bleed valve.
Background technique
Because gas turbine is when low state is run, gas compressor state is lower, not enough for the bleed air pressure obturaged, and therefore the low state of gas turbine effect of obturaging is poor, easily causes inefficacy of obturaging, lubrication leakage.For head it off, by bleed valve, obturage 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, usually reach more than 200 DEG C, cannot be solved by common electromagnetic valve; And the on-off mode of machinery valve is generally low-pressure valve closing, high pressure valve open, is not inconsistent with the control overflow of bleed.
Summary of the invention
The object of the invention is the control of whether circulating to solve gas under high temperature condition, spy provides a kind of stepless adjustable mechanical servo switch bleed valve.
The invention provides a kind of stepless adjustable mechanical servo switch bleed valve, it is characterized in that: described stepless adjustable mechanical servo switch bleed valve to comprise bottom valve 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: bottom valve, 1 is fixedly connected with valve baffle plate 2, valve baffle plate 2 is connected by connecting rod with valve top 3, housing 4 is connected by clamping bolt 11 with end cap 5, piston 6 is enclosed within the outside at valve top 3, piston 6 is coordinated with housing 4 by Sealing 8, and pressure regulator 10 is arranged in the middle part of end cap 5 by screw thread, and spring 7 is arranged between piston 6 and pressure regulator 10, relief opening 9 is positioned at the side lower of housing 4, and lock silk 12 is locked on clamping bolt 11 and pressure regulator 10.
Described pressure regulator 10 is hollow structure, and outside is threaded, and extend into one end of housing 4 inside with shoulder structure.
Described Sealing 8 is graphite seal.
By rotary pressure controlling device 10, can the pressure of Regulation spring 7, realize the action of valve baffle plate 2, and then control the function whether pressurized gas circulate.
In accompanying drawing, the direction of arrow indication is that pressurized gas flow to.
Advantage of the present invention:
Stepless adjustable mechanical servo switch bleed valve of the present invention, solves the automatic cut-out of the bleed of obturaging of the low state of gas turbine and high state, on the gas turbine that can be widely used in similar demand or equipment.
