Description
Technical field
The utility model is related 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.
Utility model content
The purpose of this utility model is to provide a kind of rational in infrastructure, valve pressure testing device of favorable working performance.
Technical solution of the present utility model is：
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,
Piece screw mandrel that is driven by handwheel is set on right base, and the left and right two ends of screw mandrel set left-handed, dextrorotation trapezoidal thread respectively, left,
Right clamped seat is coordinated with the left and right two ends of the screw mandrel by feed screw nut pair respectively, is filled on left and right base to left and right folder
Two guide rods that tight bearing is oriented to；Left and right compression hydraulic cylinder, left and right clamping liquid are set respectively on left and right clamped seat
The piston rod head of cylinder pressure is connected with left and right pressure testing plate respectively, and left and right compression hydraulic cylinder is sphere self-centering form；Left and right
Multiple stress sections with the flange contact of subject pressure valve, stress section and hydraulic cylinder solenoid valve control machine are set respectively on pressure testing plate
Structure is connected.
Multiple stress sections are in pressure testing plate with being uniformly distributed on valve flanges sealing contact surface.
The utility model is directly pressed from both sides using the convenient modular construction dismantled, adjusted, the clamped seat of double guiding, hydraulic cylinder
Hold pressure testing plate, and Universal self-centring, it is ensured that pressure testing plate sealing ring is circumferentially uniformly contacted with valve flanges sealing surface；Pressure testing plate with
The circumferential uniform multiple stress sections of valve flanges sealing contact surface, when reaching the compression of setting, send signal, hydraulic cylinder electromagnetism
Valve is commutated, and 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.
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 structural representation of base and clamped seat.
Embodiment
A kind of valve pressure testing device, including left and right base 1,2, left and right base is connected by standing screw 3, left and right bottom
A piece screw mandrel 5 driven by handwheel 4 is set on seat, and the left and right two ends of screw mandrel set left-handed, dextrorotation trapezoidal thread respectively, left and right
Clamped seat is coordinated with the left and right two ends of the screw mandrel by feed screw nut pair respectively, is filled and is clamped to left and right on left and right base
Two guide rods 6,7 that bearing is oriented to；Left and right compression hydraulic cylinder 8,9 is set respectively on left and right clamped seat 13,14,
The piston rod head of left and right compression hydraulic cylinder is connected with left and right pressure testing plate 10,11 respectively, left and right compression hydraulic cylinder be sphere from
Centering form；On left and right pressure testing plate respectively set with subject pressure valve flange contact multiple stress sections 12, stress section with
Hydraulic cylinder solenoid valve control mechanism is connected.
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.
