Embodiment
In order to preferably understand technical scheme, below by specifically embodiment and with reference to accompanying drawing
It is described in detail：
Refer to Fig. 1 and Fig. 2, the flow and flow resistance characteristic experimental rig of a kind of swing check valve of the invention, including
The rocking arm 2 and bonnet 16 (or test tool) connected positioned at the flap 1 and flap 1 of valve inner, in addition to connecting rod 6, manipulation
Bar 14, support 13 and handwheel 10.Rocking arm 2 can drive flap 1 to be moved around flap rotating shaft 19.
Rocking arm 2 is fixedly connected with block 3 provided with one.Referring to Fig. 3, being fixedly connected with block 3 is provided with an ear slot 31.Connecting rod 6 is adopted
It is connected with 4 bearing pins and split pin by ear slot 31 with being fixedly connected with block 3.
Manipulation rod through-hole is offered on bonnet 16, control stick 14 is plugged on straight down to be manipulated in rod through-hole.Refer to figure
4, control stick 14 is connected with connecting rod 6 by bearing pin 7.In valve inner a guide pad 18 is provided with close to the position of bonnet 16.Refer to
Fig. 5, the arc structure being engaged with control stick is offered on guide pad 18, control stick 14 abuts against the arc structure of guide pad 18
Interior, guide pad 18 can shorten the arm of force when control stick 14 moves up and down, and prevent control stick 14 from bending.
Support 13 is vertically arranged in the top of bonnet 16, and action bars 14 is built in inside support 13 by trapezoidal nut 11.Please
Refering to Fig. 6, the surface of support 13 indicates graduation mark or scale, and its scale is obtained by measuring and calculating the open position of flap
Go out, and the Direct Travel easily shown is converted to by angle stroke.The positive and negative of support 13 is provided with to perforate, by that can be seen to perforate
To control stick 14 therein, on actuating lever 14 provided with flap position index line 141.It is corresponding to manipulate when flap 1, which is in, closes
Index line 141 is in the zero graduation line position of support 13 on bar 14.Seal with O ring is provided with the connecting portion of support 13 and bonnet 16
Structure 15.
Referring to Fig. 7, the top of control stick 14 be provided with one section can self-locking trapezoidal thread, the top of support 13 is provided with fixing groove
131, the trapezoidal thread nut 11 being engaged with control stick with trapezoidal thread is provided with the inner side of fixing groove 131, realizes control stick 14

Complete flow and flow resistance characteristic curve in the range of door full gate.
During Experiment Parameter when carrying out valve closing, Experiment Parameter step when operating procedure is with opening is similar.Valve
(see Fig. 2) is shown in a fully open operation, the aperture for needing to test first is set.Turn clockwise handwheel 10, drives trapezoidal thread nut 11
Rotation, in the presence of trapezoidal thread nut 11, control stick 14 moves downward, while connecting rod 6 and then moves downward, and promotes
Flap 1 is closed, and is stopped when the groove on control stick 14 coincides with the top groove required on support 13.Now flap
1 be already fixed to needed for test aperture, can be tested, and record the aperture of the point, flow, pressure difference, discharge coefficient etc.
Data.By that analogy, until the test of aperture point needed for the whole of completion setting.Can really it be surveyed according to all data measureds
The flow and flow resistance characteristic gone out in the closing process of swing check valve, further it is depicted as in the range of complete valve wide open degree
Flow and flow resistance characteristic curve.
The flow and flow resistance characteristic experimental rig of a kind of swing check valve of the present invention, flap is controlled using operated by handwheel
Keying, it is simple in construction, it is easy to operate, can control and fix when carrying out flow/flow resistance characteristic checking test need valve
Door aperture.And the open position of flap is accurately indicated, under measuring flap from closing to different opening in the range of standard-sized sheet
The test of actual flow/flow resistance characteristic.Flow/flow resistance characteristic of swing check valve can truly be verified.System can be allowed to set
Meter analysis obtains genuine and believable data, it is ensured that the feature and security of system.
Those of ordinary skill in the art it should be appreciated that the embodiment of the above be intended merely to explanation the present invention,
And be not used as limitation of the invention, as long as in the spirit of the present invention, the change to embodiment described above
