Abstract
The utility model discloses a kind of valve exfactory inspection armature-moment-testing device, the middle part of left hand and right hand handle is linked into an integrated entity by bearing pin, the front end of left hand and right hand handle is V-type jaw, and the V-type jaw opening of left hand and right hand handle is oppositely arranged, one stress section is set respectively in each plane of V-type jaw, and stress section is contacted with stem surface；Rear portion is set in left hand and right hand the spring for connecting left hand and right hand handle；Stress section is connected by wire with signal acquisition and amplifying circuit, signal acquisition and amplifying circuit be packed in left hand or right handgrip on display device be connected.The utility model is rational in infrastructure, simple in construction, compact using the hand handle of V-type jaw, the valve rod linear contact lay of stress section and circular cross-section in V-type plane, can be adapted to the valve rod test of plurality of specifications.
Description
Technical field
The utility model is related to a kind of valve exfactory inspection armature-moment-testing device.
Background technology
The dynamic torque size of valve, one is the selection for influenceing valve to set timing driving device, and two be to influence the energy of user
Consumption, three be to influence the reliability of valve, and same specification is with the valve of pressure, and torque is big, illustrate between sealing pair, filler and valve rod it
Between, the coefficient of friction between bearing and valve rod it is big, influence service life.Therefore the casing rigidity before valve dispatches from the factory and sealing are being done
During experiment, while doing valve torque test with pressure.But when generally valve does delivery test, installed and debugged driving
Device, surveys at the torque of drive device input, such as worm screw handwheel, then can not embody the true torque of valve, worm and gear
Transmission efficiency it is very uncertain.
Utility model content
The purpose of this utility model is to provide a kind of valve exfactory inspection torque testing rational in infrastructure, easy to use
Device.
Technical solution of the present utility model is：
A kind of valve exfactory inspection armature-moment-testing device, it is characterized in that：Including left hand and right hand handle, the middle part of left hand and right hand handle
Linked into an integrated entity by bearing pin, the front end of left hand and right hand handle is V-type jaw, and the V-type jaw opening of left hand and right hand handle is relative
Set, a stress section is set respectively in each plane of V-type jaw, and stress section is contacted with stem surface；In left hand and right hand rear portion
The spring of connection left hand and right hand handle is set；Stress section is connected by wire with signal acquisition and amplifying circuit, signal acquisition and amplification
Circuit be packed in left hand or right handgrip on display device be connected.
The utility model is rational in infrastructure, simple in construction, compact using the hand handle of V-type jaw, can at carrier openings with
Valve rod is connected, the valve rod linear contact lay of stress section and circular cross-section in V-type plane, can be adapted to the valve rod test of plurality of specifications.
Brief description of the drawings
The utility model is described in further detail with reference to the accompanying drawings and examples.
Fig. 1 is the structural representation of the utility model one embodiment.
Fig. 2 is the equipment of valve pressure testing schematic diagram.
Embodiment
A kind of valve exfactory inspection armature-moment-testing device, including left hand and right hand, 1,2, the middle part of left hand and right hand handle passes through pin
Axle 3 is linked into an integrated entity, and the front end of left hand and right hand handle is V-type jaw, and the V-type jaw opening of left hand and right hand handle is oppositely arranged,
One stress section 4 is set respectively in each plane of V-type jaw, and stress section is contacted with stem surface；Rear portion is set in left hand and right hand
Connect the spring 5 of left hand and right hand handle；Stress section is connected by wire 6 with signal acquisition and amplifying circuit 7, signal acquisition and amplification
Circuit be packed in left hand or right handgrip on display device 8 be connected；Pull hand when, contact stress is believed by stress section
Number by wire after signal acquisition and amplifying circuit, shown in display device.
Application method：Before valve is suppressed, by valve exfactory inspection armature-moment-testing device from the gland of valve rack 9
Fastening window is stretched into, and is clipped in stem surface；Hand handle is pulled during experiment with pressure, is passed through contact stress signal by wire by stress section
After signal acquisition and amplifying circuit, shown in display device.There are valve body 10, drive device 11 in Fig. 2.
