Specific embodiment
The present invention will be further described in conjunction with the embodiment in attached drawing below:
As shown in Figure 1 and 2, the invention mainly comprises clamp body 1, mounting clip sleeve 2, vernier knob 5, support gauge head 12 and flow measurements
Device 13.
Mounting clip sleeve 2 is connected by connector on clamp body 1,2 rear end of mounting clip sleeve is connected through a screw thread lock sleeve 3, lock sleeve 3
Rear end is connected through a screw thread seal nipple 4.
The long needle-valve 17 that can be slid back and forth is equipped in mounting clip sleeve 2, long 17 front end of needle-valve connects atomizer 18.Atomizer 18
It is inlaid in support gauge head 12.Support gauge head 12 is inlaid in screw set 11, and screw set 11 is threadedly attached in clamp body 1
On.
12 front end of support gauge head connects flow measurement device 13, and support gauge head 12 is equipped with connection flow measurement device
13 and 18 spout of atomizer fuel injection passage.
Pocketed springs 8 on the long needle-valve 17,8 front and back end of spring are respectively equipped with gasket 7 and sliding sleeve 9, and the positioning of gasket 7 connects
It connects on the location and installation step of long needle-valve 17, sliding sleeve 9 is sleeved on long needle-valve 17 and rear end in contact seal nipple 4.
The vernier knob 5 is connected through a screw thread seal nipple 4, and 17 rear end face of end in contact minute hand valve, micro- before vernier knob 5
5 rear end of knob is adjusted to connect displacement sensor 6.The vernier knob 5 is using thousand parted hairs.
Pedestal 14 is connected by connector on the clamp body 1, pedestal 14 realizes peace of the clamp body 1 on work top
Dress.
The mounting clip sleeve 2, which is equipped with, is connected to the fuel feed hole 16 that long needle-valve 17 slides cavity, and clamp body 1 is equipped with connection oil inlet
The oil inlet passage 15 in hole 16,15 input end of oil inlet passage connect fuel inlet fitting 10.
Assembly application method of the invention: firstly, according to the corresponding clamp body of size selection of injector nozzle matching parts to be measured and
Gauge head is supported, and vernier knob and seal nipple are fastened on clamp body.Then, gasket, spring and sliding sleeve are assembled to
The tail end of injector valve guarantees that the couple between needle-valve tail end and sliding sleeve cooperates.Then, support is surveyed by screw set
Head, injector nozzle matching parts, gasket, spring and sliding sleeve are tightened on clamp body, using pedestal by the above-mentioned measured material assembled
It is mounted in flow measurement test-bed；Finally, needle-valve position is compressed using manual fine-tuning knob be limited in atomizer (reason
It is zero) the couple flow (until when flow is zero) of turn-on flow rate test-bed measurement at this time, then by continuously adjusting by lift
The needle lift of vernier knob control injector nozzle matching parts is saved, measurement obtains the couple flow under different needle lifts.
Long needle-valve of the invention and atomizer constitute injector nozzle matching parts to be measured, and pass through screw set and different sizes
Support gauge head injector nozzle matching parts are tightened on clamp body, exist between nozzle needle valve body large end face and clamp body at this time flat
Face sealing, prevents high-pressure fluid from leaking out；And it (is maintained by gasket and spring, simultaneously in the tail portion of long needle-valve by sliding sleeve
Sliding sleeve and needle-valve tail portion are couple cooperations) and sealing shroud (being pressed on clamp body by vernier knob) mutual cooperation sealing, prevent
Only high-pressure fluid enters the tail end of the long needle-valve of atomizer and generates higher pressure；High-tension measurement fluid enters fixture from fuel inlet fitting
Then body is entered in the oil suction chamber of injector nozzle matching parts by oil inlet passage, and keep certain measurement pressure.Vernier knob simultaneously
Can continuous quick metering pin valve lift (its lift range value can be determined by displacement sensor), the long needle-valve of atomizer is in both ends liquid
The position of vernier knob limitation is opened and rapidly risen under the action of pressure, and high-pressure fluid can only be sprayed from the oil nozzle of unlatching at this time
It is flowed out at hole, the fluid finally sprayed enters the flow measurement device of rack, and obtains accurately and effectively measurement result rapidly.This
Outside, further types of intermediate oil inlet formula fuel injection nozzle matching can be realized by different adaptation gauge heads and various sizes of clamp body
Part flow measurement.Compared with original measuring device, designing and developing to provide and preferably examine for long needle-valve co-rail oil injection mouth couple
Core means.
The invention has the advantages of simple structure, compactness and reasonable structure, and test is efficient and convenient, and test result is accurate and reliable, can measure different liters
The high pressure flow of long needle valve spray nozzle coupler under journey, so as to individually examine long needle valve spray nozzle coupler discharge stability and
Consistency.
