Fluid flows through external load, so as to realize the test to external load, in test, fluid flows to many respectively from main line passage 1
Individual tie point passage 2, identical damping element 3 and pressure sensor 4 is flowed separately through in the tie point passage 2 and from first
Fluid issuing flows out, and carries out test by external load and subsequently enters the second bypass passage 5, flows through damping regulating valve 6 from second
Fluid issuing flows out, because fluid is allocated into different branch from same main line；
The utility model provides identical resistance in the external load front end of each branch road, because fluid comes from same source
Pressure at head, therefore shunting is identical, when the numerical value of the display of pressure sensor 4 in each tie point passage 2 is identical, explanation
Pressure difference between each head of tie point passage 2 and afterbody is identical, and each tie point passage 2 is damped using identical in addition
Element 3, therefore each head of tie point passage 2 is also identical with the resistance between afterbody, and each first is flowed through so as to can represent
The fluid flow of paths 2 is identical, and due to the difference of external load, the condition such as its resistance, pressure, temperature has larger difference
It is different, influence can be produced on the fluid flow for flowing through, therefore the pressure of external load front end can be ensured by adjusting damping regulating valve 6
When identical, i.e., during the numerical value all same of the display of pressure sensor 4 in each tie point passage 2, it is ensured that flowing through external negative
Carry test sample flow identical, can so accomplish accurate test.
Additionally, also including the PID controller 8 being connected with pressure sensor 4 and damping regulating valve 6, the PID controller 8
The pressure sensor 4 and damping regulating valve 6 of the bypass passage 5 of each tie point passage 2 and second, the PID control are connected respectively
Device 8 is the general purpose controller of in the market, and the desired value P0 of pressure sensor 4 is first set first, if actual value is different from P0 values,
PID controller 8 is controlled to damp regulating valve 6 accordingly and is adjusted, such as：If the actual value of pressure sensor 4 is more than P0, increase
The aperture of regulating valve 6 is damped, if the actual value of pressure sensor 4 is less than P0, reduces the aperture of damping regulating valve 6, so that real
Now automate accurate shunting.
Additionally, also including the main line mass flowmenter being arranged on main line passage 1, the setting of the main line mass flowmenter
Can facilitate carries out control to the total flow on main line.
Additionally, the main line passage 1 and tie point passage 2 are integral type structure, also including being arranged on main line passage 1
It is used to connect pressure sensor for connecting the flowmeter interface 23 of main line mass flowmenter and being arranged on tie point passage 2
4 pressure sensor interface 24, due to the damping element 3 on each tie point passage 2 be both needed to it is identical, therefore test
Before need to do substantial amounts of previous work, therefore this module will be shunted, damping and each connecting interface are done on one module, greatly
Space of components is reduced, and each split channel is identical, it is time-consuming using the preceding debugging without carrying out damping element 3 again,
And the setting of each interface is also convenient for patching for exterior part.
