In order to achieve the above object, the utility model embodiment provides following technological scheme:
A kind of quiet High Pressure Difference guide balanced type modulating valve, be made up of valve body, valve, valve base sealing pad, valve seat, sleeve, spool, seal ring, hold-down ring, middle flange plate, bonnet, matrix liner, filler, Gland, hold-down grid, electronic type straight stroke electric actuating mechanism, connection baffle plate, restricting orifice and valve rod, it is characterized in that, all parts welds together, at valve inlet, place is provided with restricting orifice, and restricting orifice is provided with two groups of non-circular pod apertures facing each other; Valve seat is equipped with valve rod, valve rod is installed with spool, spool has equalizing orifice, be provided with sleeve around spool, valve rod, spool, housing part are placed in the lumen of valve body, and sleeve surface is by row punching, throttle element is installed with in hole, throttle element is cylindrical body, and surface is provided with non-circular through hole, and bottom is also provided with perforation; Valve body and bonnet are sealed by hold-down ring and seal ring; Sealed by valve base sealing pad between valve seat and valve body, middle flange plate is connected with valve body stud, nut; By filler, matrix liner sealing between valve rod and bonnet; Gland, hold-down grid are placed in above filler, matrix liner is positioned at below condiment, and with filler close contact, hold-down grid is connected by nut, bolt with bonnet, electronic type straight stroke electric actuating mechanism and bonnet are connected together by hexagon head bolt, hexagon nut and spring washer, connecting baffle plate is placed in outside bonnet, and electronic type straight stroke electric actuating mechanism is placed in and connects above baffle plate.
Preferred as technique scheme, the quantity of restricting orifice is two, and superposition is staggered.
The one that the utility model embodiment provides quiet High Pressure Difference guide balanced type modulating valve, compared with prior art, advantage of the present utility model is just: on restricting orifice, four bending pod apertures can increase the fluid resistance of valve, through hole on spool plays the effect of balance pressure, spool design adopts balance type structure, reduce the vibration of modulating valve, effectively can avoid cavitation phenomenon, have quiet, vibrate the advantages such as little, resistance to erosion.

In figure: 1-valve body, 2-valve base sealing pad, 3-valve seat, 4-sleeve, 5-spool, 6-seal ring, 7-hold-down ring, flange plate in 8-, 9-stud, 10-nut, 11-bonnet, 12-matrix liner, 13-filler, 14-Gland, 15-hold-down grid, 16-electronic type straight stroke electric actuating mechanism, 17-stud, 18-stud, 19-connects baffle plate, 20-hexagon head bolt, 21-hexagon nut, 22-spring washer, 23-valve rod, 24-restricting orifice.
Embodiment
Below in conjunction with accompanying drawing of the present utility model, be clearly and completely described the technical solution of the utility model, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
As Figure 1-5, the one that the utility model embodiment provides quiet High Pressure Difference guide balanced type modulating valve, four bending pod apertures can increase the fluid resistance of valve, through hole on spool 5 plays the effect of balance pressure, have throttle element in sleeve 4, this sleeve, throttle element as shown in Figure 4,5, can find out that throttle element has many holes, also fluid resistance can be increased, can also effective coutroi velocity.Figure 3 shows that the structural drawing of restricting orifice, restricting orifice has 4 bending holes, is uniformly distributed; It is the structural drawing of sleeve shown in Fig. 4, sleeve is evenly equipped with thousands of holes, throttle element, as shown in Figure 5, inside the hole being inserted into sleeve, compared with there is no the situation of restricting orifice, sleeve, throttle element, bending groove adds the damping of fluid motion, play multilevel decompression effect, and the aperture of modulating valve and flow are linear relations, electric actuator can the size of adjust flux more easily.
Spool has equalizing orifice, utilizes seal ring and hold-down ring to stop equalizing orifice inner fluid to leak outside.Spool is acted on by all pressures up and down, only need overcome the frictional force at the places such as balanced seal circle and hold-down ring, therefore join less final controlling element and just can bear very high pressure reduction during spool action.
During valve closing, the position of valve rod, spool and valve seat as shown in Figure 2; Valve rod is upwards mentioned, and fluid can enter the top of barrel bore by the through hole on spool, reach the effect of guide's balance pressure, can reduce the vibration of modulating valve.When valve rod continues to mention to highest order, fluid just can by the endoporus of throttle element, and arrive the outlet of valve, in this time, the flow of valve is very little, and pressure drop is very large.Valve rod continues to move upward, and fluid can pass through more throttle element, and the flow of valve increases, and pressure drop reduces, large pressure drop during small flow, little pressure drop during large discharge.The process of control valve opening from 0% to 100% (stroke constantly changes), flow rises to 100% from 0%; Otherwise, then decline.
The above; be only embodiment of the present utility model; but protection domain of the present utility model is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; change can be expected easily or replace, all should be encompassed within protection domain of the present utility model.Therefore, protection domain of the present utility model should described be as the criterion with the protection domain of claim.
