Abstract
The invention relates to a multifunctional high-differential-pressure regulating valve which comprises a valve body, valve seats, an inner sleeve, a serrated gasket, a valve element, pressure balancing holes, a serrated gasket, a spring, a V-shaped filler, and the like, wherein a straight-through double-valve-seat form and an angle structure in which a medium flows from top to bottom are used to weaken the collapsing force of flash evaporation; the interior and the exterior of the valve body are machined and molded according to smooth curves; four pressure balancing holes are arranged on the valve element to reduce the push-off moment; a structure with multiple symmetrical holes and three layers of sleeves is used to reduced noise and cavitation; a structure with a reduced guiding clearance is used to reduce the device vibration; a valve body flow channel is manufactured into an S shape to lighten the impact force; the filler is manufactured into a V shape to have small frictional force and long service life; the middle of the filler is provided with the spring to lengthen a filler chamber; and sealing is adjusted to effectively prevent leakage.
Description
Technical field:
The present invention relates to a kind of control gear that can be used to regulate flow, pressure and the liquid level of medium; four pressure compensation openings especially are set on spool; employing reduces guiding clearance and limit lateral amplitude and constructs the relieving apparatus vibration, function such as reach low noise, friction, no cavitation, protection environment, increase the service life.
Background technique: present high-differential-pressure regulating valve, can not solve noise, vibration, cavitation problem, bring many unnecessary troubles to the user, bring environmental issue simultaneously.
Summary of the invention:, exist deficiency in problems such as solving noise, vibration, cavitation at existing high-differential-pressure regulating valve.The invention provides a kind of multifunctional high-differential-pressure regulating valve, form by valve body, valve seat, inner sleeve, toothed pad, spool, pressure compensation opening, toothed pad, spring, V-type filler etc.
The technical solution adopted for the present invention to solve the technical problems is: take straight-through double seated valve form, the angular structure that medium flows in top-down direction weakens the collapsing force of flash distillation; Valve body is inside and outside presses smoothed curve machining moulding, and four pressure compensation openings are set on the spool, reduces to release moment; With three layers of tube-in-tube structure of many symmetrical holes, reduce noise and cavitation erosion; With reducing the guiding clearance structure, come the relieving apparatus vibration; Valve flowing channel S shape alleviates impact force; Filler is made V-type, and frictional force is little, increases the service life; A spring is set in the middle of filler, and lengthening filler chamber adjusts sealing, effectively prevents the generation of revealing.
The invention has the beneficial effects as follows: be user-friendly to, simple in structure, reach low noise, friction, no cavitation, protection environment, increase the service life.
Description of drawings:
Fig. 1 is that product structure schematic representation, Fig. 2 are that product component schematic representation, Fig. 3 are the product component schematic representation.Among the figure, 1, valve body 2, valve seat 3, outer sleeve 4, middle sleeve 5, inner sleeve 6, toothed pad 7, spool 8, pressure compensation opening 9, valve rod 10, gland parts 11, toothed pad 12, double-screw bolt 13, nut 14, filler baffle ring 15, spring 16, V-type filler 17, Gland 18, double-screw bolt 19, pressing plate 20, nut
Embodiment
Take straight-through double seated valve form; In the valve mechanism design, the angular structure that adopts medium to flow has in top-down direction significantly reduced the number of bubbles of impact valve body (1) wall, thereby has weakened the collapsing force of flash distillation; Press smoothed curve machining moulding inside and outside the valve body (1), strengthen hardness and flow velocity and exist; Four pressure compensation openings (8) are set on the spool (7), and pressure is cancelled each other when making medium pass through equalizing orifice (8), reduces the thrust of medium to spool (7), thereby reduces the release moment of required actuator; Adopt many symmetrical holes multilayer sleeve (3,4,5) design, reduce under High Pressure Difference, to reduce the noise of compressible fluid and avoid cavitation erosion; Employing reduces guiding clearance and limit lateral amplitude structure, comes the relieving apparatus vibration; Valve body (1) adopts the S type runner design of smooth type, avoids expanding rapidly, alleviates the impact force of fluid to the valve wall; Filler (16) system meter is made V-type, under the effect of pressure, can produce one radially and tight power and valve rod (9) tightly connect airtight more and touch, good sealing effect, frictional force is little, increases the service life; A spring is set in the middle of filler (16), and lengthening filler (16) chamber makes filler (16) after long-term use is loosening; spring (15) expansion is automatically adjusted sealing; effectively prevent the generation revealed, the protection environment reaches low noise, friction, no cavitation purpose.
