Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
In order to make of the present utility modelly to realize technological means, creation characteristic, reach object and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
As shown in Figure 1, a kind of New Type Flow Control Valve, comprise main valve body, the entrance point of described main valve body 1 reducing reducing gradually greatly of serving as reasons, in main valve body 1, be provided with the He You chamber, left chamber being interconnected, lower end, the left chamber of main valve body 1 is provided with bellows 2, between main valve body 1 and bellows 2, be provided with diaphragm 3, in the left chamber of main valve body 1, be provided with the first valve rod 5, the first valve rod 5 is positioned at left chamber, the first valve rod 5 is provided with two spherical valve cores 4 and forms automatic linkage spool, spherical valve core 4 diameters that are positioned at upper end, left chamber are larger, the spherical valve core right angle that is positioned at lower end, left chamber is less, deadweight by spherical valve core 4 regulates hydraulic pressure, the first valve rod 5 lower ends and diaphragm 3 offset, diaphragm 3 downsides are provided with the spring 6 offseting with bellows 2, in the right chamber of main valve body 1, be provided with the second valve rod 10, second valve rod 10 one end are stretched in right chamber and with the regulating spool 7 in right chamber and are connected, the other end of the second valve rod 10 stretches out right chamber and is connected with the flow control device 8 on main valve body 1, regulating spool 7 is provided with and detects the pressure transducer 9 that flows through right chamber hydraulic pressure, described pressure transducer 9 is connected with flow control device 8, in flow control device 8, store default hydraulic pressure, the hydraulic pressure parameter of its collection is transferred to flow control device 8 by pressure transducer 9, when the hydraulic pressure parameter gathering when pressure transducer 9 is less than or greater than default hydraulic pressure, flow control device 8 is declined or is risen by the second valve rod 10 regulating and controlling spools 7.Wherein said regulating spool 7 is taper valve core, is provided with the straight hole shape flow channel corresponding with taper valve core in the right chamber of main valve body 1, and the face of all crossing between taper valve core and flow channel contacts sealing.
With reference to Fig. 1, after the working fluid that the inlet pressure of main valve body 1 is P1 is flowed through spool, pressure becomes P2, while entering beneath film chamber again after driving regulating spool 7, pressure is P3, its pressure reduction is P2-P3, flowing through and driving the flow after regulating spool 7 is G=KV √ (P2-P3), when driving after the set positions of regulating spool 7, its sectional area is constant, KV is definite value, in the time that P2-P3 is constant, flow G is just constant, automatic linkage valve element position is subject to the pressure difference control of P2 and P3, its sectional area of spool and valve base chamber changes thereupon, as drive the position of regulating spool to reset, the negotiability of automatic linkage spool and the pressure reduction of P1-P2 also change.In the time that working fluid pressure P1 increases, the flow of the instantaneous automatic linkage spool of flowing through increases, pressure P 2 also will improve, now P2-P3 pressure reduction increases, and has destroyed original balance, and automatic linkage spool is moved to valve seat direction, reduce cross section of fluid channel, increase resistance, make P2 pressure difference return to again original value, ensured flow.Constant, otherwise in like manner.
More than show and described basic principle of the present utility model and major character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; that in above-described embodiment and specification, describes just illustrates principle of the present utility model; do not departing under the prerequisite of the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.Claimed scope of the present utility model is defined by appending claims and equivalent thereof.
