The dynamic balance adjusting valve that the present embodiment provides plays the effect of balance, refers at flow and setsPrerequisite under, the flow of dynamic balance adjusting valve not with import and export change in pressure.
According to flow formula(negotiability that kv is valve, direct with the openings of sizes of valveRelevant), in the situation that pressure reduction increases, guarantee kv reduces according to special ratios, can realize flowBalance, is stabilized in setting flow.
The flow equilibrium process of dynamic balance adjusting valve the present embodiment being provided below in conjunction with Figure 12 do intoThe introduction of one step and explanation. The flow equilibrium function of the dynamic balance adjusting valve that the present embodiment provides mainly relies onThe equilibrium relation of inner core 16 and elastomeric element (as spring 18) realizes. Shown in Figure 12, due toPressure-sensitive chamber is communicated with intake antrum, and therefore the hydraulic pressure P1 of intake antrum is identical with the hydraulic pressure in pressure-sensitive chamber, also just makesPressure in pressure-sensitive chamber is also P1. Current enter the inner chamber of spool, namely urceolus 15 from water inlet 151Inner chamber, i.e. water stream channel, in this process, current have produced pressure drop, and the pressure of the inner chamber of spool is becomeP2 (P2 < P1). Now, the hydraulic pressure between water stream channel and pressure-sensitive chamber has pressure reduction, and then makes pressure-sensitiveThe both sides of plate 163 produce pressure differential, and this pressure differential is (P1-P2) * S; Wherein S is sense pressing plate functionThe projected area of face, the acting surface both side surface area of pressure-sensitive plate 163 equates. In such cases, pressure-sensitive plate163 move up, and then make inner core 16 with respect to urceolus 15 upward slidings. Due to elastomeric element settingBetween pressure-sensitive plate 163 and holder 17, and holder 17 the spool bottom 20 and urceolus 15 that connectFixing, therefore, the mobile of pressure-sensitive plate 163 can elasticity of compression parts.
Increasing under the prerequisite of elastomeric element deflection, can obtain balance, i.e. a P1*S=P2*S+F. WhenWhen fluctuation occurs system pressure, be increased to example with pressure, P1 increases and becomes P1 ', and P2 is increased to P2 ',And Δ P1 > Δ P2, therefore the pressure-sensitive balance of P1 ' * S > P2 ' * S+F is broken, and inner core 16 is fortune upwardsMoving. The flow equilibrium mouth of inner core 16 is by partial occlusion, and then makes the negotiability of dynamic balance adjusting valveKV value reduces. Elastomeric element is compressed simultaneously, and elastic force increases and becomes F ', until realize new balance P1 '* S=P2 ' * S+F '. This process is the process of a dynamic change, and P1 ', P2 ' and F ' moment are allChanging to realize final balance. In this new balance,Because before and after valvePressure differential deltap P increases, and the new negotiability KV ' of valve reduces. The dynamic equilibrium that finally can ensure to circulate is adjustedThe water flow value of joint valve is constant, ensures that water flow value is for setting flow.
Than the content of introducing in background technology, the dynamic balance adjusting valve that the present embodiment provides is logicalCross the effect between pressure-sensitive plate 163 and elastomeric element, after hydraulic pressure is changed, the stream on inner core 16The area of amount balance port can correspondence change, and then the circulation area of delivery port 152 is changed,And then the negotiability of change dynamic balance adjusting valve, and then make to ensure dynamically after hydraulic pressure changesThe flow of balance regulating valve remains at setting flow. And the parts of stating in realization adjusting are not allowed yetBe prone to damage, the dynamic balance adjusting valve that therefore the utility model embodiment provides has better flow and adjustsJoint effect.
The dynamic balance adjusting valve that the present embodiment provides can also comprise actuator 1, cover 10 and valve damAxle 12. Actuator 1 is installed on the valve body top cover 7 of valve body 27, and the cover 10 that dams is snug fit at urceolus 15Inside, valve shaft 12 is fixed on the cover 10 that dams, and the movement of valve shaft 12 can drive the cover 10 that dams to move. LogicalNormal actuator 1 is fixed on valve body top cover 7 by actuator locking nut 2. In the cover 10 that dams is arranged onThe top of cylinder 16, the cover 10 that dams can slide to dwindle gradually with respect to urceolus 15 circulation of delivery port 152Area, until shutoff delivery port 152, actuator 1 has and can apply and make it along damming cover to valve shaft 12The valve shaft drive division that 10 glide directions move. The valve shaft drive division of actuator 1 drive valve shaft 12 to move and thenIndirectly drive the cover 10 that dams to slide, and then realize the flow of dynamic balance adjusting valve is set, trueSurely set flow. In order to ensure sealing, valve shaft 12 is provided with the cover sealing ring that dams with damming to cover between 1028. In addition, above-mentioned movement of damming cover 10 can shut delivery port 152, and then realizes dynamic equilibrium adjustingThoroughly closing of valve, closes sealing in order to realize, preferred, on the end face of the delivery port 152 of urceolus 15Be provided with annular groove 156, in annular groove 156, be laid with sealing ring 13, dam cover 10 in the time of disconnect position withSealing ring 13 sealing docking.
