Description
Technical field
The present invention relates to a kind of valve pressure testing device.
Background technology
Valve is used for the device and pipe network system of all trades and professions, and different industries, the standard that different system is quoted is not quite similar,
Cause the valve mechanism length of same size, pressure rating different, flexible, compact, adjustable, the scope of application of experimental rig
Extensively, advantageously reduce cost, improve operating efficiency.
The content of the invention
It is an object of the invention to provide a kind of rational in infrastructure, valve pressure testing device of favorable working performance.
The present invention technical solution be：
A kind of valve pressure testing device, it is characterized in that：Including left and right base, left and right base is connected by standing screw, left and right bottom
A piece screw mandrel driven by handwheel is set on seat, and the left and right two ends of screw mandrel set left-handed, dextrorotation trapezoidal thread, left and right folder respectively
Tight left and right two ends of the bearing respectively with the screw mandrel are coordinated by feed screw nut pair, are filled on left and right base and are clamped branch to left and right
Two guide rods that seat is oriented to；Left and right compression hydraulic cylinder, left and right compression hydraulic cylinder are set respectively on left and right clamped seat
Piston rod head be connected respectively with left and right pressure testing plate, left and right compression hydraulic cylinder be sphere self-centering form；In left and right pressure testing
Multiple stress sections with the flange contact of subject pressure valve are set respectively on plate, and stress section connects with hydraulic cylinder solenoid valve control mechanism
Connect.
Multiple stress sections are in pressure testing plate with being uniformly distributed on valve flanges sealing contact surface.
Application method：Hand wheel rotating screw mandrel, left and right branch is driven by the left and right nut distribution on clamped seat
Seat is moved, and only movement does not rotate left and right nut；Clamped seat is slightly moved to pressure testing plate and connect substantially with valve flanges sealing surface
Touch, the pressure testing plate for being fixed on piston rod head is pressed on flange sealing surface by clamping hydraulic cylinder working, realize sealing；When up to
To setting compression when, send signal, piston rod is not moved in hydraulic cylinder magnetic valve commutation, hydraulic cylinder pressurize.
The present invention directly clamps examination using the convenient modular construction dismantled, adjusted, the clamped seat of double guiding, hydraulic cylinder
Pressing plate, and Universal self-centring, it is ensured that pressure testing plate sealing ring is circumferentially uniformly contacted with valve flanges sealing surface；In pressure testing plate and valve
The circumferential uniform multiple stress sections of flange seal contact surface, when reaching the compression of setting, send signal, hydraulic cylinder magnetic valve is changed
To piston rod is not moved in hydraulic cylinder pressurize, and clamped seat is run simultaneously in the case where feed screw nut drives, efficiency high.
