In order to solve the problems of the technologies described above, the present invention is solved by following technical proposals:
The variable spiral flow controller of integrated form, comprise throttle body, throttle pipe (5) and throttling adjustable lever are set in the described throttle body, the throttling adjustable lever is connected with an end of spiral throttling rod, the other end of spiral throttling rod is connected with retaining spring, and the diameter of throttle pipe is 0.1-500mm.
As preferably, described throttle pipe and spiral throttling rod intersect, and the intersection area is the static pressure chamber.
As preferably, described throttle pipe leading portion is the capillary tube of slenderness ratio 〉=20, and back segment is to leave the clearance type throttle pipe that the gap is 0.10～0.30mm.
As preferably, also be provided with the fixed restriction chamber that communicates with throttle pipe in the described throttle body, the fixed knot fluid is set in the fixed restriction chamber.
As preferably, described throttle body also comprises end cap, divides oil and fixed body, divides oil and fixed body to be provided with knob.
As preferably, spiral lamination distributes on the described spiral throttling rod.
As preferably, described fixed restriction chamber communicates with the static pressure chamber.
As preferably, described throttling adjustable lever is connected for holding out against with the spiral throttling rod.
As preferably, the side of described throttle body arranges plural oil outlet.
As preferably, the below of described throttle body is provided with pressure gauge connection, unloading port and oil-feed port.
Every chamber all need dispose pressure in the prior art, regulates and relatively disperses not concentrate, and regulates problems such as unreliable, easily static-pressure system is produced harmful effect.The present invention solves in the prior art each oil pocket all need join manometric drawback, and reducing influence link, raising static-pressure system rigidity.
The present invention is owing to adopted above technological scheme, has significant technique effect: by being provided with spiral lamination spiral throttling rod, utilize intrasystem static pressure, formed one little feedback function flow controller has been arranged, improved the static-pressure system rigidity greatly, solved the error part in theoretical calculating and the actual debugging simultaneously, variable range is big on the basis that guarantees system rigidity, can remedy shape and trueness error that part is brought because of machining accuracy and assembly quality.
Description of drawings
Fig. 1 is the structural representation of the embodiment of the invention 1.
The toponym that each number designation refers in the above accompanying drawing is as follows: wherein 1-throttle body, 2-end cap, 3-minute oil and fixed body, 4-knob, 5-throttle pipe, 6-throttling adjustable lever, 7-spiral throttling rod, 8-retaining spring, 9-fixed knot fluid, 11-pressure gauge connection, 12-unloading port, 13-oil-feed port.
Embodiment
The present invention is described in further detail with embodiment below in conjunction with accompanying drawing 1:
The variable spiral flow controller of integrated form as shown in Figure 1, comprises throttle body 1, throttle pipe 5 and throttling adjustable lever 6 are set in the described throttle body 1, throttling adjustable lever 6 is connected with an end of spiral throttling rod 7, and the other end of spiral throttling rod 7 is connected with retaining spring 8, and the diameter of throttle pipe 5 is 6mm.
Also be provided with the fixed restriction chamber that communicates with throttle pipe 5 in the throttle body 1, fixed knot fluid 9 is set in the fixed restriction chamber.
Spiral lamination distributes on the spiral throttling rod 7.Adopt the variable spiral segment flow structure of distribution spiral lamination on the spiral throttling rod 7, under system pressure and spring action, variable spiral throttling masthead is lived the throttling adjustable lever, to guarantee to adjust static pressure chamber, back system stability.The spiral lamination that the processing of variable spiral throttling rod is meticulous, it is crossed oily length and can regulate by the throttling adjustable lever, to change static pressure oil pocket and system pressure than β (β=Ps/Pr Ps system charge oil pressure; Pr static pressure oil pocket pressure).
The fixed restriction chamber communicates with the static pressure chamber.The fixed restriction chamber communicates with the rear end in static pressure chamber, when the static pressure cavity pressure is big, makes that fixed knot fluid 9 right atrial pressures in the fixed restriction chamber are bigger, thereby promotion fixed knot fluid 9 is moved to the left, thereby reduces the oil inlet quantity in static pressure chamber.
