Description
Technical field
The present invention relates to a kind of two guiding regulation structure.
Background technique
Existing axial flow control valve generally adopts balance valve core list guide structure and one-level helical teeth drive mechanism, the valve of this structure often occurs that seal ring damages in natural gas transport uses, the leakage of valve is made to exceed standard and cause the waste of rock gas, in use usually there is flank of tooth phenomenon of rupture and stroke retardation phenomenon in one-level helical teeth drive mechanism, thus impacts the normal operation of valve and degree of regulation.
Summary of the invention
The object of this invention is to provide a kind of pair of guiding regulation structure, the conversion of vibration, interference stream, erosion homenergic can be become minimum, reduce vibration and the noise of Conversion of Energy generation, decrease flow resistance simultaneously.
A kind of two guiding regulation structure, comprise valve body, valve rod and spool, its specialization is: described valve rod comprises main shaft, the bottom of this main shaft is fixedly connected with a splined shaft, on this splined shaft, fixed cover is equipped with tooth sector, this tooth sector engages with a rack shaft, and on this rack shaft, fixed cover is equipped with spool.
Wherein the prolonged section of rack shaft extend out to outside spool, the prolonged section outside this spool is set with secondary noise reducing plate, and this secondary noise reducing plate has some through holes, and is Spielpassung between this prolonged section and secondary noise reducing plate thus can plays leading role.
Wherein one-level regulating sleeve is installed outside spool.
After adopting modulating valve of the present invention, because body cavity is straight-through fairshaped, the concentric motion mode of spool and valve body flows vibrating, disturbing, the conversion of erosion homenergic becomes minimum, reduces vibration and the noise of Conversion of Energy generation, decreases flow resistance simultaneously.Set up another road spool guide structure in the outlet port of valve, make the motion of spool more steady, effectively protect the working life of seal ring and the accuracy of degree of regulation.Valve transmission adopts secondary gear drive mechanism, solves the maintenance of valve that valve in use causes due to the fracture of the flank of tooth.Adopt secondary dislocation type step-down denoising structure, solve and use the problem that site pressure is unstable and noise is large.

Accompanying drawing 1 is structural representation of the present invention;
Accompanying drawing 2 is transmission principle schematic diagram of the present invention;
Accompanying drawing 3 is working principle schematic diagram of the present invention.
Embodiment
As shown in Figure 1, 2, 3, the invention provides a kind of two guiding regulation structure, comprise valve body 1, valve rod 2 and spool 5, described valve rod 2 comprises main shaft 9, the bottom of this main shaft 9 is connected with splined shaft 11, and specifically flat being overlapped by connecting shaft of flat and splined shaft 11 upper end of main shaft 9 bottom is connected, and on this splined shaft 11, fixed cover is equipped with tooth sector 10, this tooth sector 10 engages with a rack shaft 3, and on this rack shaft 3, fixed cover is equipped with spool 5.
Wherein the prolonged section of rack shaft 3 extend out to outside spool 5, this prolonged section is set with secondary noise reducing plate 6, specifically on noise reducing plate, open some through holes according to field working conditions, realize decrease of noise functions, noise reducing plate is opened pilot hole rack shaft 3 prolonged section and pass through pilot hole, move around in guide sleeve 7 in pilot hole and put into practice the regulatory function of valve, noise reducing plate loads valve body 1 outer end guard ring and compresses, and guard ring outside thread is connected with valve body 1 internal thread.Outside spool 5, one-level regulating sleeve 4 is installed in addition, the shape of pipe part being beaten metering orifice is adopted at this one-level regulating sleeve 4, one-level regulating sleeve 4 cylindrical coordinates with valve body 1, and endoporus coordinates with spool 5, and rack shaft 3 moves the adjustment realizing flow with movable valve plug 5.Wherein adopt balanced seal circle 8 to seal between one-level regulating sleeve 4 and valve body 1, the leakage of valve adopts between balance valve core 5 and one-level regulating sleeve 4 and adopts firewire to seal.
Improvements of the present invention are: another road guiding has been set up in one end of spool 5, effectively raise the stationarity that spool 5 moves, the working life extending balanced seal circle 8 and improve the accuracy of Flow-rate adjustment.Secondary noise reducing plate 6 meet valve under high pressure transport gas time effectively reduce the noise of valve, secondary buck functionality can be played simultaneously, make the using scope of valve more extensive.
Using method of the present invention and working principle are:
The invention provides a kind of two guiding regulation structure, compared with prior art its improvements mainly comprise: another road guiding is set up in one end of the rack shaft 3 of band movable valve plug 5 movement and realizes dual-guiding structure; Valve event adopts two-stage gear transmission structure to realize the movement of spool 5; The secondary step-down noise reducing plate at sleeve one-level step-down noise reduction and valve export place can realize dislocation type two-stage step-down denoising structure.
Its advantage is as follows:
1, adopt dual-guiding structure can improve the life cycle of valve sealing ring, reduce the leakage rate of valve, avoid the waste of natural gas energy resource, energy saving.
2, adopt rational two-stage gear transmission structure, reduce the maintenance expenses of valve, extend the life cycle of valve, reduce certain three guarantees maintenance expenses.
3, adopt dislocation type two-stage step-down denoising structure, improve the usability of valve, widened the using scope of valve.
The invention provides a kind of axial flow control valve with dual-guiding structure, mainly comprise: valve body 1, main shaft 9, transmitting assemblies, balance valve core 5, secondary noise reducing plate 6, seal ring, stop sleeve etc.Be characterized in: by setting up another road guiding in spool 5 one end, make the more steady of balance valve core 5 movement, effectively raise the leakage grade of valve and the working life of seal ring.Through on-the-spot probationary certificate, adopt a kind of two guiding regulation structure in natural gas transport after, the working life of seal ring is significantly improved, and the amount of leakage of valve also significantly reduces, and decreases rock gas waste unnecessary in conveying and has saved the energy.By improving the type of belt drive of valve, making driving component destruction in use obtain obvious improvement, extending the replacement cycle of valve standby redundancy simultaneously.By setting up secondary step-down noise reducing plate at valve export place, certain step-down noise reduction can be played, reducing the pollution that NOISE ON ENVIRONMENT produces.
