Embodiment
Below by embodiment also in conjunction with the accompanying drawings, the technical solution of the utility model is further described in detail.
Embodiment:
Adjustable dynamic flow balance valve as shown in Figure 1, valve body 1 is a right angle threeway, form by upper valve body and horizontal valve body, horizontal valve body respectively is provided with the screw of a setting pressure table by water intake and water outlet direction, by the water outlet direction one next door is arranged, directly flow to water outlet from water intake in order to stop medium.There is a through hole C with horizontal valve body axis oblique upper valve body and horizontal valve body joint by the water outlet direction in next door, with so that medium flows into water outlet behind the ring joint head piece by valve seat 11 endoporus and the formation of spool a conical surface.Horizontal valve body middle part is provided with it uses the valve seat 11 that is threaded.Slide in the upper valve body valve opening and joining regulating sleeve 3, the two center line unanimity, being provided with O-ring seals 9 between the fitting surface can move up and down with regulating sleeve 3, in case medium leaks.Upper valve body top is provided with spacing back-up ring 8, in order to place restrictions on regulating sleeve 3 to the adjusted height, when regulating sleeve 3 transferred to the extreme higher position, the omoplate in its stage casing just in time contacted with the lower end surface of spacing back-up ring 8, place restrictions on it and continue to move up, at this moment the rigidity minimum of spring 4; Otherwise, when locking nut 10 and handwheel 5 when being adjusted downward to extreme lower position, the rigidity maximum of spring 4.Poppet shaft 2 is installed in the central authorities of regulating sleeve 3, and its center line is consistent with the upper valve body center line, and is vertical with horizontal valve body center line.Poppet shaft 2 upper end cunnings fit among the pilot hole d of regulating sleeve 3, on 1/2nd length of poppet shaft 2 upper end axostylus axostyles, be carved with two triangular grooves in diametric(al), the gas-tight phenomenon of top cavity volume when moving to eliminate it, improve the flexibility of motion, the axostylus axostyle cunning of poppet shaft 2 lower ends fits in the hole of guide plate 13, and under free state, poppet shaft 2 can be slided along the center line easy on and off of upper valve body.Poppet shaft 2 stage casings are provided with cone plug a, and the endoporus formation narrow shape annular area with valve seat 12 plays throttling action, the flow size that control is passed through, and annular area changes with inlet outlet pressure differential; Helical spring 4 is enclosed within on the axostylus axostyle of poppet shaft 2 upper ends, one end is located on the outstanding spring seat in poppet shaft 2 stage casings, the other end is located on the end face of regulating sleeve 3 respective interior bores, certain pre compressed magnitude is arranged after the installation, therefore spring 4 has one to make the lift off a seat thrust of 12 endoporus of spool a all the time, even the tendency that annular area increases; The internal thread of handwheel 5 screws on the outside thread of upper valve body, and the endoporus in the middle of the handwheel upper end slides on the axostylus axostyle of regulating sleeve 3 upper ends, and locatees with back-up ring 6, and therefore, when handwheel 5 rotated, regulating sleeve 3 can and then not rotate, and can only move up and down.According to different intake pressures and pressure surge, can clockwise or rotate counterclockwise handwheel 5, make regulating sleeve 3 liftings, in order to the rigidity of Regulation spring 4, rigidity is regulated suitable back and is locked with locking nut 1.Rolled straight burr on handwheel and locking nut one 10 outer round surface; There is a lug below at horizontal valve body middle part, is screwing bottom 15 in the lug, and guide plate 13 is equipped with in bottom 15 tops, guide plate 13 usefulness jump rings 12 location.Bottom 15 belows are provided with adjusting screw 17, rotation adjusting screw 17 just can change the annular area between spool a and valve seat 12 endoporus, can play the effect of setting flow, with locking nut 2 16 lockings, the outer round surface of adjusting screw 17 and locking nut 2 16 has also rolled straight burr behind the flow set.
Working principle: under the state of not water flowing, spool a makes valve be in fully open position under the pressure of spring 4; After the water flowing, when import hydraulic pressure P1 was lower than startup hydraulic pressure, medium flowed to water outlet by aforesaid annular gap from water intake; If import hydraulic pressure equals to start hydraulic pressure, this moment, flow reached the setting flow value; If import hydraulic pressure P1 is greater than starting hydraulic pressure, import hydraulic pressure overcomes the resistance of spring 4 and back pressure, spool a is moved up, when the pressure of suffered thrust of poppet shaft 2 inlet end and spring 4 and back pressure sum balance, poppet shaft 2 stop motions, rest on the equilibrium position, suppose that this moment, annular area was a Δ, the flow by valve is determined by two end pressure differential deltap P=P1-P2 and annular area Δ so.Though the pressure differential deltap P of valve two ends increases on the equilibrium position, owing to reducing of annular area Δ, it is constant therefore to keep water supply; If import hydraulic pressure P1 raises suddenly or exports hydraulic pressure P2 and reduces suddenly in the water flowing process, promptly pressure differential deltap P increases, and spool a rests on the new equilibrium position so, and in like manner, it is constant to keep water output; If instead import hydraulic pressure P1 reduces suddenly, or outlet hydraulic pressure raises suddenly, be that pressure differential deltap P reduces, spool a moves down under the promotion of spring 4 so, until resting on the new equilibrium position, though this moment, the pressure reduction of valve two ends reduced, because annular area increases, it is constant therefore to keep water output.This shows, the equilibrium position of spool a, after spring 4 rigidity were determined, by the decision of intake-outlet pressure reduction, and no matter what equilibrium position spool a rests on, it was constant to keep water output all the time, promptly maintains the flow value of setting all the time.
The limit position that spool a effectively regulates is the cylindrical body b of spool a below, has just entered in the endoporus of valve seat 12 (the poor approximately 1-2mm of the pressure reduction of the two), if spool a continues to move up, because the annular area Δ no longer changes, it is constant therefore no longer to keep water output.Therefore, constant for keeping water output, for different intake pressures and variation in pressure, the rigidity of spring 4 should be adjusted to desired value.
Along with improving constantly of people's quality of life, when the user has when significantly improving flow requirements, need only rotate counterclockwise adjusting screw 17 to correct position and get final product, regulate suitable back with locking nut 2 16 lockings, flow value can read from flowmeter.Position shown in Figure 1 is the position of setting the flow maximum, and the flow value of valve when dispatching from the factory by service condition and the traffic requirement of production firm according to the user, is adjusted on test stand before dispatching from the factory.After setting new flow value, the rigidity of spring 4 also changes to some extent, if necessary, need readjust the rigidity of spring 4.
