Property part deformation extent realizing the setting of the water flow pressure difference of water supply line and inlet channel.
Illustrate that the balance of differential pressure balancing valve provided in an embodiment of the present invention is former below based on above-mentioned preferred version
Reason：
The differential pressure balancing valve that the present embodiment is provided is arranged on heating, on the water return pipeline of air conditioning system, heating,
In the water system of air conditioning system, the water flow pressure of the water return pipeline connected with water chamber is fixed, is Fig. 1
In P3；Pressure-sensitive chamber connects with water supply line, then the water flow pressure of pressure-sensitive intracavity is the P1 in Fig. 1；
Intake antrum is connected with inlet channel, and the water flow pressure in intake antrum is the P2 in Fig. 1.Generally, P3 will not
Change with more next fluctuation the in the external world of pipe network system, that what is changed is P2 and P1.The present invention is implemented
The balanced action of the differential pressure balancing valve that example is provided is to ensure that the difference between P1 and P2 is definite value.
Fig. 2 is refer to, below to receiving as a example by the inner core 8 of the differential pressure balancing valve on water return pipeline
, there is following balance during 8 stress balance of inner core in power analytic explanation：
P1S=P2S++F1+F2 (1)
Wherein；S- pressure-sensitive sleeve senses significant surface；F1- adjusts initial tension of spring K1- and adjusts spring
Coefficient；ΔL1- adjusts amount of spring compression；F2- stage clip elastic force；K2- stage clip coefficient of elasticity；ΔL2- stage clips compress
Amount.
I.e.：
ΔP=P1-P2=(F2+F1)/S=(K2ΔL2+K1·ΔL1)/S (2)
When water flow pressure P1 of water supply line increases, the moment, water flow pressure P3 of water return pipeline is constant,
Supply head (P1-P3) increase of pipe network, now the drive valve cone 12 of inner core 8 is towards closing outlet 62
Direction movement, now whole differential pressure balancing valve resistance increase, i.e., (P2-P3) increase, due to P3 not
Become, then P2 increases；In the same manner conversely, i.e. when water supply line water flow pressure P1 reduce when, the moment,
Water flow pressure P3 of water return pipeline is constant, and the supply head (P1-P3) of pipe network reduces, and inner core 8 then can band
Dynamic valve cone 12 towards the direction movement for opening outlet 62, the now resistance of differential pressure balancing valve reduce,
(P2-P3) reduce, due to P3 it is constant, then P2 then reduces.By formula (1) and (2) and tie
Close and state knowable to analysis, when P1 changes, inner core 8, the first elastomeric element and the second elastomeric element
In the presence of, enable to P2 and change therewith, it is final to cause the difference of P1 and P2 constant, as
Setting value.Therefore, in the range of the operting differential pressure of the differential pressure balancing valve for providing in the present embodiment, ensure that
P1-P2 is setting value.
When resistance inside the controlled loop of pipe network changes, such as a certain branch road shut-off, the controlled ring
The drag overall increase on road, the moment, P2 increases, inner core 8 can drive valve cone 12 to hold towards differential pressure balancing valve
The direction movement opened so that now the resistance of whole differential pressure balancing valve reduces, finally causes P2 to reduce again,
Because resistance occurs in the inside of controlled loop, therefore water flow pressure P1 of water supply line is constant, whole pressure
Differ from balanced valve itself internal drag of controlled loop is implemented to adjust, and then enable to P2 and do not change,
The final difference caused between P1-P2 is constant.Therefore, the work of the differential pressure balancing valve for providing in the present embodiment
In pressure differential range, ensure that P1-P2 is setting value.
Preferably, the second elastomeric element adjusts spring 16 and is set in valve shaft 17 to adjust spring 16.
Regulation spring 16 is set in valve shaft 17 and ensure that the flexible stable of regulation spring 16.
Referring again to accompanying drawing 1, a kind of specific hand wheel structure is present embodiments provided, provided
Handwheel includes handwheel inner sleeve 19, handwheel outer sleeve 20 and preset pressure indicateing arm 21；The handss
Wheel inner sleeve 19 is set in the valve body top cover 2, and can rotate relative to the valve body top cover 2；
The handwheel outer sleeve 20 is fixed on the valve body top cover 2, and with handwheel head 1；Outside the handwheel
There is gap between sleeve 20 and the handwheel inner sleeve 19；Preset pressure indicateing arm 21 and the handss
Wheel inner sleeve 19 screw thread coordinates, and the turning in the handwheel inner sleeve 19 with the handwheel outer sleeve 20
Dynamic circumferential spacing cooperation；The handwheel outer sleeve 20 has the axially extending form along valve shaft 17,
The side of the form is provided with pressure scale, and the preset pressure indicateing arm 21 is used to indicate the pressure
Power scale.Above-mentioned handwheel outer sleeve 20, handwheel inner sleeve 19 and preset pressure indicateing arm 21 form silk
Thick stick mechanism, as staff's knob handwheel head 1 further causes preset pressure indicateing arm 21 to move further
The pressure scale of different parts is pointed to, and then causes the default scale of set pressure differential.Operator can
To read the setting pressure of the differential pressure balancing valve that the present embodiment is provided by reading preset pressure indicateing arm 21
Difference, i.e. the setting difference of P1 and P2.
The differential pressure balancing valve that the present embodiment is provided can also include blocked valve 4, and blocked valve 4 is used to enter
The current part of water cavity is introduced in intake pressure detection means, and then detects the water flow pressure of inlet channel,
That is P2.In addition, water chamber can be provided with the pressure measurement mouth 14 for detecting pressure of return water, i.e. P3.
Only describe some one exemplary embodiments of the present invention by way of explanation above, undoubtedly,
For one of ordinary skill in the art, in the case of without departing from the spirit and scope of the present invention, can
To be modified to described embodiment with a variety of modes.Therefore, above-mentioned accompanying drawing and description
It is inherently illustrative, should not be construed as the restriction to the claims in the present invention protection domain.
