Technical field
The utility model relates to a kind of self-contained pressure regulator, particularly relates to a kind of outside resources that need not, and only utilizes and is transferred medium self variation in pressure to carry out the self-powering type minute-pressure modulating valve that minute-pressure is regulated.
Background technique
Self-contained pressure regulator is a kind of outside resources that need not, and only utilizes and is transferred medium self variation in pressure to carry out pressure controlled energy-saving modulating valve product.When the upstream pressure of the existing required control of self-contained pressure regulator needs greater than 100Kpa, could implement effectively sensitive pressure and regulate.Need carry out bigger improvement to the structure of existing self-contained pressure regulator; a kind of minute-pressure modulating valve of pilot pressure smaller or equal to 100Kpa that be suitable for needing to regulate is provided; to be applicable to that various industrial furnace fuel system, oil are preserved protection gas at goods or oil depot basin, heat treatment protects the automatic adjusting of pipe-line systems such as gas to control, and guarantees system's security of operation.
Summary of the invention
The purpose of this utility model is the shortcoming that exists at prior art, and a kind of minute-pressure adjusting, self-powering type minute-pressure modulating valve that control accuracy is high of being suitable for is provided.
The purpose of this utility model is achieved in that a kind of self-powering type minute-pressure modulating valve, comprise control mechanism and actuator, actuator comprises stifle 1, valve body 2, spool 3, valve rod 4, trim ring 5, valve gap 6, film sheet 19, guide sleeve 20, valve seat 21 and balance spring 22 etc.Control mechanism comprises film chamber 7, control diaphragm 8, upper film chamber 9, pallet packing ring and component such as seal ring 10, membrane cover 11, Regulation spring 12, adjustment disk 13, cover cap 14, spring seat 15, thrust ball bearing 16, stroke limit bar 17 and pallet 18 down.Control mechanism connects with actuator by valve rod, and is installed on the valve gap 6.Regulating setting pressure can adjust by the adjustment disk of regulating in the control mechanism 13.Valve outlet end pressure tappings and control mechanism suction port with joining PRESSURE PIPE be connected, act under the normal state that the control diaphragm upwards pressure and the downward pretightening force of Regulation spring balances each other, spool also is in state of equilibrium.
In technique scheme, film sheet 19 is separated valve body 2 and valve gap 6 and sealing, makes between valve rod 4 and the valve gap 6 and exempts from packing seal, obviously reduces the surface friction drag of valve opening and closing element action, has improved degree of regulation.
In technique scheme, the ultrathin folder of control diaphragm 8 employings high-intensity fiber fabric elastomer diaphragm, the position that diaphragms 8 move up and down is controlled in 17 restrictions of the stroke limit bar in the membrane cover up and down, plays protection control diaphragm moving range, effectively improves its working life.
In technique scheme, between spool 3 and the stifle 1 balance spring 22 is housed, with balance valve core assembly self gravitation, can improve the reaction sensitivity of valve to variation in pressure.
In technique scheme, the thrust ball bearing 16 of packing into below spring seat 15 causes in the time of can effectively avoiding rotating adjustment disk 13 that Regulation spring 12 twists, and the problem of control accuracy is regulated in influence.
This self-powering type minute-pressure modulating valve has pressure and sets convenience, and adjustable pressure is low, the stable action sensitivity, but and descend interference-free setting value to be adjusted advantages such as setting in working order.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described further.
Self-powering type minute-pressure modulating valve as shown in the figure comprises control mechanism and actuator, and actuator comprises stifle 1, valve body 2, spool 3, valve rod 4, trim ring 5, valve gap 6, film sheet 19, guide sleeve 20, valve seat 21 and balance spring 22 etc.Control mechanism comprises film chamber 7, control diaphragm 8, upper film chamber 9, pallet packing ring and component such as seal ring 10, membrane cover 11, Regulation spring 12, adjustment disk 13, cover cap 14, spring seat 15, thrust ball bearing 16, stroke limit bar 17 and pallet 18 down.Control mechanism connects with actuator by valve rod, and is installed on the valve gap 6.Regulating setting pressure can adjust by the adjustment disk of regulating in the control mechanism 13.
The valve body 2 of earlier sealing gasket, valve seat 21 being packed into, valve body 2 upper end-hole of again sealing gasket, guide sleeve 20 being packed into.Spool 3 usefulness nuts and valve rod 4 are fastened as one, valve rod assembly is passed valve seat 21 from valve body 2 lower ends, the valve rod 4 and fastening with nut of again film sheet 19, trim ring 5 being packed into passes valve rod 4 upper ends to valve gap 6 and is inserted in valve body 2, and is with stud, nut that valve body 2 and valve gap 6 is fastening.On stifle 1, install balance spring, be inserted in valve body 2 lower end mouth and fastening with nut.Following membrane cover is inserted in valve rod 4 upper ends, with nut that itself and valve gap 6 is fastening.To play pallet, control diaphragm 8 to be inserted in valve rod 4 successively with top tray again, the thrust ball bearing 16 of packing into below the spring seat 15 is connected as one with nut is fastening again.To go up membrane cover and be contained in down membrane cover and tighten, Regulation spring 12 will be put into spring seat 15, again adjustment disk 13 will be screwed in the cover body of membrane cover.Valve outlet end pressure tappings and control mechanism suction port with joining PRESSURE PIPE be connected.By debugging, adjustment disk 13 is adjusted to adjusting pilot pressure setting value, refilled cover cap 14.
Its working principle is: when valve export pressure during greater than setup pressure value, introducing down by suction port, the pressure of film chamber raises, acting on the active force that makes progress on the control diaphragm increases, the compression adjustment spring, the drive valve rod moves up, the circulation area of valve seat and valve core chamber is reduced, drop to setting value and reach balance up to downstream pressure.When outlet end pressure was elevated to certain value, spool and valve seat closure were closed medium runner and are guaranteed security of system.In like manner, when reducing as valve export pressure, the active force that acts on the control diaphragm reduces, and initial tension of spring promotes valve rod and moves down, and the circulation area of valve seat and valve core chamber is increased, and is elevated to setting value and reaches balance up to downstream pressure.
