Embodiment
Contrast accompanying drawing below, by the description to embodiment, the effect and principle of work etc. of the specific embodiment of the present invention as the mutual alignment between the shape of involved each component, structure, each several part and annexation, each several part are described in further detail:
As shown in accompanying drawing 1-accompanying drawing 6, the present invention is a kind of retaining valve opening pressure detecting device, described retaining valve opening pressure detecting device comprises device body 1, device body 1 is installed can along the pressure transducer 2 of device body 1 movement, pressure transducer 2 connects with the sensor contact 4 that can contact with retaining valve 3, between the valve body 5 of retaining valve 3 and one-way valve spring 6, DC circuit 7 being set, DC circuit 7 being installed the pilot lamp 8 for detecting DC circuit 7 break-make.
Described device body 1 is set to square platy structure, device body 1 is arranged recessed sensor chute 9, pressure transducer 2 is contained in sensor chute 9 by part 10 active card that clamps of inverted T-shaped, and pressure transducer 2 is set to can along the structure of sensor chute 9 movement.
The body side 12 of described device body 1 arranges rectangular-shaped orienting lug 11, orienting lug 11 is arranged coarse adjustment gathering sill 13, orienting lug outside surface 22 is arranged draw-in groove 23, arranging in draw-in groove 23 can along the coarse adjustment slide block 24 of draw-in groove movement, the side of described coarse adjustment slide block 24 approaching device body 1 is connected with pressure transducer 2 by the connecting link 25 through coarse adjustment gathering sill 13, the opposite side of coarse adjustment slide block 24 is connected with coarse adjustment slide block push rod 14, and described pressure transducer 2 is set to the structure that can show sensor contact 4 bearing pressure numerical value.
Described retaining valve 3 is set to be installed on the structure on device body 1, and when described retaining valve 3 is installed on device body 1, the sensor contact 4 of pressure transducer 2 is set to the structure that can contact with the ball valve 20 in retaining valve 3.
Described device body 1 is arranged baffle plate I 15 and baffle plate II 16, baffle plate I 15 and baffle plate II 16 form U-shaped structure with attaching plate elements 17, and attaching plate elements 17 is sleeved on coarse adjustment slide block push rod 14, and is fixedly connected with between coarse adjustment slide block push rod 14.
Described retaining valve opening pressure detecting device also comprises regulating rod 18, regulating rod 18 is arranged through the structure of baffle plate II 16, regulating rod 18 one end is resisted against on pressure transducer 2, the other end is set to the structure of extending baffle plate II 16, be set to the structure be threaded between regulating rod 18 with baffle plate II 17, regulating rod 18 is set to can along the structure of baffle plate II 16 spinning in and out.
The described regulating rod 18 extending baffle plate II 16 one end is arranged the fine setting rocking handle 19 for rotating regulating rod 18.
In retaining valve opening pressure detecting device of the present invention, when needing the minimum opening pressure detecting retaining valve 3, first retaining valve 3 is installed on device body 1, now, the sensor contact 4 of pressure transducer 2 is set to the structure of the ball valve 20 can aimed in retaining valve 3, at this moment, pull coarse adjustment slide block push rod 14, coarse adjustment slide block push rod 14 promotes pressure transducer 2 and moves along sensor chute 9, thus make sensor contact 4 near one-way valve spring 6, and make sensor contact 4 promptly contact ball valve 20, at this moment, pressure transducer 2 can show the numerical value of pressure size, now, use regulating rod 3 again instead and slowly regulate pressure transducer 2 further, when slowly regulating pressure transducer 2 further, turn fine setting rocking handle 19, regulating rod 18 is to device body 1 side precession, thus promote pressure transducer 2 further slowly to the ball valve 20 to retaining valve 3, thus can very slowly to ball valve 20 imposed load of retaining valve 3, at this moment, the bright and dark of the pilot lamp 8 in DC circuit 7 can be observed, pilot lamp 8 is dimmed, namely prompting stops continuing the signal to retaining valve 3 imposed load, at this moment, regulating rod 18 keeps original invariant position, minimum pressure numerical value required when retaining valve 3 is opened can be read by pressure transducer 2.
Pick-up unit of the present invention, utilize DC circuit 7 indicating lights connected in series 8 and retaining valve 3, judge that the unlatching of retaining valve 3 is with closed by the bright of pilot lamp 8 and extinguishing, when wherein pilot lamp 8 extinguishes, the pressure value that pressure transducer 2 is measured is exactly the minimum opening pressure of retaining valve 3:
Opening pressure=unlatching pressure × useful area.
Like this, the minimum pressure required for open check valve can just be conversed equivalently.
In pick-up unit of the present invention, regulate coarse adjustment slide block push rod 14, pressure transducer can be moved along sensor chute 9, and the setting of baffle plate I 15 and baffle plate II 16, the effect promoting pressure transducer movement can be played, as shown in Fig. 1-Fig. 3, baffle plate I 15 promotes pressure sensor reach, and II 16, baffle plate plays the effect pushing back pressure transducer 2.
After having detected the minimum opening pressure of a retaining valve 3, by regulating rod 18 and the reposition of coarse adjustment slide block push rod 14, thus the testing of next retaining valve 3 can be carried out.
Pick-up unit of the present invention, utilizes the minimum opening pressure measuring retaining valve 3 to substitute the minimum unlatching pressure directly measured required for open check valve 3.Pick-up unit of the present invention needs independent air pressure and hydraulic pressure generator unlike direct air pressure and hydraulic means, just replace air pressure and hydrostatic transmission by simple vibrational power flow, structure of the present invention, very large elasticity is there is, also delay of response unlike hydraulic means unlike gas transmission; Secondly, this mechanism, to the not requirement of the sealing of measurement mechanism, can greatly reduce processing cost like this, and does not affect the accuracy of measurement effect.
Retaining valve opening pressure detecting device of the present invention, the minimum opening pressure of retaining valve can be convenient for measuring out, and relative to hydraulic pressure, pneumatic shuttle, structure is simple, producing process is easy, cost reduces, and detection method is simple, Detection results than conventional method more close to actual conditions.
