Key of the present invention is that the component in the voltage-regulating transformer valve body (11) can mount and dismount from the top of voltage-regulating transformer valve body (11), and has been equipped with the excess pressure cutout device of integral type for axial flow pressure regulator.The rubber film component part of top mounted axial-flow type voltage regulator (3) is positioned at the top of voltage-regulating transformer valve body (11), and valve pocket is positioned on the runner axis of voltage-regulating transformer valve body (11), and the two is separated from each other.Valve pocket is divided into before and after preceding valve pocket (6) and back valve pocket (9) two sections, adopts semicircle anchor ear (7) chucking to cuing open, and perhaps adopts the collar nut chucking, perhaps screw lock.Before valve pocket (6) and back valve pocket (9) when being tightened, its junction surface can be to pressing from both sides pressure regulation valve port (8), can also be to picking up the silencing apparatus (flow-limiting plate) (10) of rectifying noise-reduction and limited flow effect.The entry end of voltage-regulating transformer valve body (11) rises and has connect a circular sleeve (18), the cylindrical of sleeve (18) one ends is used to support preceding valve pocket (6), back valve pocket (9) stretches into the outlet end of voltage-regulating transformer valve body (11), behind preceding valve pocket (6) and back valve pocket (9) chucking, the valve pocket band pressure regulation valve port (8) and can be slided freely on the runner axis, adopts the sealing of O RunddichtringO between valve pocket and the sleeve (18).Fixed a stem bearing (17) at the front end of sleeve (18), valve rod (15) one ends insert stem bearing (17) center, valve rod (15) axis and runner dead in line, the other end reaches pressure regulation valve port (8) and locates, spool (12) is fixed on the valve rod (15) with gland nut, silencing apparatus (10) also can be selected to be close to spool (12) and be fixed on the valve rod (15), its effect be the same to being sandwiched in preceding valve pocket (6) and back valve pocket (9).
During work, rubber film component part (3) links to each other with back valve pocket (9) with preceding valve pocket (6) with shift fork (5) by driveshaft (4), the motion of rubber film component part (3) drives shift fork (5) and rotates, the pivoted arm of shift fork (5) promotes interconnected preceding valve pocket (6) and back valve pocket (9) is done axial motion, preceding valve pocket (6) and back valve pocket (9) clip-on pressure regulation valve ports (8) and the formed passage of fixing of spool (12) are controlled the throughput of fluid, reach the purpose of adjusting downstream pressure.Cut off valve port (14) and place in the sleeve (18),, and can slide freely with the sealing of O RunddichtringO.Cut off valve port (14) draw-in groove of being with tooth bar is set, this draw-in groove has been arranged, cutting off valve port (14) can link to each other by the cut-off valve controller (29) of a gear shaft (23) and voltage-regulating transformer valve body (11) outside.Cut-off valve controller (29) monitoring downstream pressure, when pressure exceeded setting range, cut-off valve controller (29) discharged gear shaft (23), cuts off valve port (14) and be close to spool (12) under the promotion of cut-off valve spring (13), block fluid is passed through, and guarantees not superpressure of downstream.
When top mounted axial-flow type voltage regulator keeps in repair on pipeline, dismounting earlier is the upper chamber cover (1) of pressure governor down, from the outside back-out of voltage-regulating transformer valve body (11) cock one (21), take out shift fork rotating shaft (20), just can take out rubber film component part (3), driveshaft (4) and shift fork (5) together then.Unload anchor ear (7), preceding valve pocket (6) and back valve pocket (9) are separated, can take out pressure regulation valve port (8), can see spool (12) this moment.Take off gland nut on the valve rod (15) with regard to desirable lower valve core (12) with spanner.Valve rod (15) be by one reach voltage-regulating transformer valve body (11) outside have strong market potential axle (16) wedging in stem bearing (17), as long as cock two (22) under voltage-regulating transformer valve body (11) outer buttons, taking-up is had strong market potential spool (16), can withdraw from valve rod (15) from stem bearing (17).Then valve rod (15), preceding valve pocket (6), back valve pocket (9) and pressure adjusting spring are taken out from voltage-regulating transformer valve body (11) top.Unload gear shaft (23) from voltage-regulating transformer valve body (11) outside, can take out cutting off valve port (14) and cut-off valve spring (13).So far, fragile parts such as rubber film component part (3), spool (12), seal ring and spring all can take out from voltage-regulating transformer valve body (11) top and carry out examination and maintenance, and need not to dismantle the installation pipeline of pressure governor.The installation of component resets and can be undertaken by the reverse order in when dismounting.
Fig. 3 is the vertical cross section of the longshore current road axis of the top mounted axial-flow type voltage regulator of another preferred embodiment of the present invention, and this axial flow pressure regulator is with the direct acting type axial flow pressure regulator of pressure adjusting spring (24) as the pressure regulation power resources.Each element is respectively (24) pressure adjusting spring among the figure, (25) latch bracket, (26) gland nut, (27) regulator bolts.Be with the different of embodiment shown in Figure 1, pressure governor shown in the present embodiment is not with pressure governor pilot valve (28), upper chamber cover (1) is provided with the spring chamber of a projection, provide pressure regulation power, all same Fig. 1 of the component structural of voltage-regulating transformer valve body inside and the structure of shut-off means, Fig. 2 by the pressure adjusting spring (24) in the spring chamber.This pressure governor adopts spring to come pressure regulation, adopt the pressure regulator valve mouth structure of axial flow again, the characteristics that reaction velocity is fast, breakout pressure is low that possess traditional direct acting type pressure governor, possess the characteristics that the axial flow pressure regulator flow coefficient is big, flow resistance is low and noise is little again, the pressure regulation that is fit to very much big flow low-pressure gas is used.
In sum, top mounted axial-flow type voltage regulator can substitute the use of traditional axial flow pressure regulator, both can be used for liquid, also can be used for gas.With the combustion gas is example, and along with the fast development that China's combustion gas is used, top mounted axial-flow type voltage regulator can be brought into play positive effect promoting the use of more of gas industry.The pressure level system of gas pipeline and changes in flow rate scope are bigger, must use specification difference, the different pressure governor of performance in a large number.And combustion gas is flammable explosion hazard gases, and the relation of the supply of combustion gas is to national economy, and country has formulated strict management regulation (as GB 50028).Used pressure governor all must regularly carry out examination and maintenance in the fuel gas supply system.Top mounted axial-flow type voltage regulator combines the advantage of multiple pressure governor, can adapt to the multistage variation and the large-scale changes in flow rate of gaseous-pressure, makes things convenient for internals to safeguard again, has been equipped with the excess pressure cutout device of integral type simultaneously, is fit to very much the selection of gas industry.
More than describe the specific embodiment of the present invention in detail, but the example of this visualization of just lifting for the ease of understanding should not be considered to be limitation of the scope of the invention.Equally; the ordinary skill of technical field all can be according to the description of technological scheme of the present invention and preferred embodiment thereof under any; make various possible being equal to and change or replacement, but all these changes or replacement all should belong to the protection domain of claim of the present invention.
