Description
Technical field
The utility model relates to the needle valves in water system, more particularly, to a kind of regulating valve of two-stage energy dissipating.
Background technique
It often needs high-pressure water to be converted into low pressure water supply in water system, also just needs the high potential energy of water to be converted into low
Potential energy+kinetic energy, namely have a conversion process of energy, it is commonly called as " energy dissipating ".This process general class valve (gate valve, shut-off valve, butterfly
Valve, ball valve etc.) it cannot achieve.Existing energy dissipating valve mainly has the medium-sized more spray orifice valves of single-stage pipe and spray orifice type piston valve, or
The more spray orifice valves of person's submerged.These telescoping valves, though also there are dissipating functions, since level-one energy dissipating can only be used, so working as pressure difference
Noise, cavitation erosion are very big when larger, and complicated mechanism, anti-rubbish ability are poor, easily failure.
Chinese patent CN1017097998 discloses a kind of multifunctional sleeve type energy dissipation valve, by Y-valve body, valve deck,
The composition such as sleeve, adjustment barrel, size piston cylinder, pressure reducing valve (guide), which is actually a pilot-operated type piston-type pressure reducing valve,
Only because its cut-off type flap has been changed to sleeve shaped (having energy dissipating effect), it you must use two large and small piston cylinders and want
Difference in areas is caused to drive adjustment barrel, such product is emphasized:
(1) self-operated type；
(2) energy dissipating (having telescopic porous head-on collision energy dissipating)；
But such product the disadvantage is that:
(1) the porous energy dissipating of level-one, energy dissipating ability is limited, and High Pressure Difference (being greater than 0.8MPa) is that noise is big, cavitation erosion is big；
(2) main valve piston cylinder makees piloted reducer, since piston has frictional force and guide's pressure reducing valve reflection speed not
Synchronous (having the phenomenon that lags) is so the pressure oscillation of (or small flow status) outlet end is very when outlet end flow has fluctuation
Greatly, end water is influenced.

The second sleeve lock for driving and sliding up and down, second jet pipe are fixed on valve body, and entrance is located at side, and is entering
Multiple discharge orifices being uniformly and symmetrically distributed are opened up at mouthful, export face outlet flow, Open Side Down for the second sleeve lock,
Top plate is connect with valve shaft.
The operation machine is fixed by the bracket on the upper head plate of the first jet pipe, and described valve shaft one end and operation machine connect
It connects, the other end is connect after sequentially passing through the upper head plate and first sleeve lock of the first jet pipe with the upper head plate of second sleeve lock.
First jet pipe is equipped with filter screen on the outside of its entrance.
The valve shaft other end is arranged PE axle sleeve outside the shaft part between the upper head plate and first sleeve lock of the first jet pipe.
First jet pipe on valve body contact face be equipped with the first sealing ring, the top and bottom of second jet pipe
The second sealing ring and third sealing ring are respectively equipped on portion and second sleeve lock contact surface.
The inlet channel bottom offers sewage draining exit.
Compared with prior art, the utility model has the advantage that
One, existing energy dissipating valve complicated mechanism, low efficiency, abrasion are big, and easily there was a mechanical failure, and the utility model uses
Arbor direct drive mode is operated, mechanism is simple, is less prone to mechanical breakdown.
Two, the utility model carries filtering function, is effectively prevented rubbish into the first jet pipe, to eliminate energy dissipating valve
Easily by the situation of rubbish card resistance failure, while the number of rubbish is inferred in the variation of observable first order pressure difference and second level pressure difference
Amount guarantees that valve operates normally so that opening soil cleaning port in time clears up rubbish.
Three, existing energy dissipating valve is level-one head-on collision energy dissipating, and pressure difference is big, and noise vibration is big, and easily appearance cavitation erosion, the service life is short,
And this valve uses two-stage energy dissipating, every grade of pressure difference only has the 50% of existing level-one energy dissipating valve, significantly reduce vibration, noise and
Cavitation erosion, is that life of valve greatly improves.
