Specific embodiment
With reference to the accompanying drawings and detailed description the present invention is described in detail：
As shown in figure 1, the fire hydrant hydraulic sealing test device of the present invention, including water pressure testing board, pneumatic cylinder, locking bolt, water inlet
Pipe, supercharging water pipe and booster pump.
Water pressure testing board includes leg, table top and fire hydrant fixture, and table top is arranged on leg, and table top central authorities are provided with
Instrument connection, instrument connection is used for pouring water toward in fire hydrant, and instrument connection bottom is provided with water pot, and water pot connects water inlet pipe and pressurized water
Pipe.Fire hydrant keeper is respectively fixedly connected with the table top around instrument connection, for fire hydrant bottom inlet is aligned test
Hole.Fire hydrant keeper is provided with the locking bolt hole towards instrument connection.Height between locking bolt hole and table top and fire hydrant bottom method
The thickness of blue disk is adapted.
Pneumatic cylinder is respectively fixedly connected with the table top of fire hydrant keeper periphery, and the piston rod of fire hydrant is respectively facing and disappears
Fiery bolt keeper.Pneumatic cylinder has four, is located at respectively on the diagonal of table top corner.The each self-driven locking bolt of four pneumatic cylinders stretches out
And retraction.
Locking bolt is respectively fixedly connected with the piston rod end in pneumatic cylinder and is socketed on the locking bolt of fire hydrant keeper respectively
Hole.Fire hydrant keeper is fixing, and locking bolt is movable, and locking bolt stretches out the flange in the locking bolt hole of keeper to fire hydrant bottom
On disk.Due to being provided with least four locking bolts, reach ring flange from least four directions, ring flange is locked in hydraulic pressure examination
On platform, and then fire hydrant is locked on water pressure testing board.
Water inlet pipe one end is connected with instrument connection, and the other end is connected with running water pipe, and water inlet pipe is provided with inlet valve.First lead to
Cross tap water hydraulic to supply water, the space in fire hydrant and pipeline is full of, speed is faster.The front opening water intaking valve of test is permissible
Discharge water entrance water inlet pipe, closes water intaking valve water inlet pipe and the water of fire hydrant can be stoped to flow out in test.
Supercharging water pipe one end is connected with instrument connection, and the other end is connected with the delivery port of booster pump, and booster pump is provided with pressure
Table.Booster water pump produces high hydraulic pressure, for pressurizeing, tests hydraulic pressure bearing performance and the sealing property of fire hydrant to fire hydrant.
Specific operation process is：Fire hydrant is arranged on water pressure testing board, is directed at instrument connection；Booster air pump switchs, and makes
The piston rod of cylinder stretches out, and drives locking bolt to extend out in the bottom flange dish of fire hydrant, makes fire hydrant be fastened securely installation；Open
Water intaking valve, is municipal pipeline pressure now to fire hydrant pressure of supply water, first opening this pressure can prevent from pressurizeing suddenly leading to water
Outer spray；Open booster pump, adjust pressure in rated pressure 2.4MPA, to fire hydrant pressurization, 2 minutes No leakage of timing then test conjunction
Lattice.
As shown in figure 1, the direction that directly extends radially out of the external part of locking bolt is gradually reduced, the external part of locking bolt be semicircle,
Taper or truncated cone-shaped are so that during locking bolt slides on fire hydrant ring flange, being gradually increased to the pressure of ring flange, disappearing
Fiery bolt is more tightly fixed on water pressure testing board, reduces leak.And more convenient for smoothly extending out to locking bolt on ring flange, more
Easily locking fire hydrant.
As shown in figure 1, being additionally provided with height conversion part between locking bolt and the piston rod of pneumatic cylinder, make the position height of locking bolt
Position height less than piston rod.Height conversion part is a contiguous block or connects box.Two ends are respectively arranged with bolt hole, lock
The piston rod of bolt and pneumatic cylinder is threadedly connected to the bolt in the hole at height conversion part two ends respectively, after being easy to the damage of height conversion part
Or the replacing after locking bolt abrasion.The flange thickness of fire hydrant bottom be generally less than pneumatic cylinder bottom between piston rod between
Away from so by the height arranging a height conversion part reduction locking bolt, making locking bolt more be adapted to the thickness of fire hydrant ring flange, making
Locking fire hydrant is tightr, more seals, and reduces leak.
As shown in figure 1, fire hydrant keeper is the cartridge towards instrument connection for the opening, cartridge opening is towards fire hydrant, cartridge
The length that open bottom is stretched out to instrument connection direction to the length that instrument connection direction is stretched out more than cartridge open top.Locking bolt hole sets
Put the cartridge rear wall central authorities relative to cartridge opening in cartridge.Because cartridge opening is that bottom tilts to instrument connection so that installing
When fire hydrant, the ring flange of fire hydrant bottom is easier to be slipped to accurate location from cartridge opening.Self-locking sealing antitheft box simultaneously
Use, the contact surface between fire hydrant keeper and locking bolt is less, frictional force is less, and cartridge be connected with table top more firm
Gu.
As shown in figure 1, also including pneumatic cylinder fixed bin, pneumatic cylinder fixed bin bottom is fixedly connected on the platform of water pressure testing board
Face and top are opened wide, and pneumatic cylinder fixed bin afterbody is provided with locking bolt, pneumatic cylinder be arranged in pneumatic cylinder fixed bin and
Afterbody is locked by locking bolt, is provided with backing plate between pneumatic cylinder afterbody and locking bolt.Locking bolt can with spinning in and out,
And then compress pneumatic cylinder afterbody, and then lock pneumatic cylinder.By being locked in pneumatic cylinder in fixed bin, facilitate tearing open of pneumatic cylinder
Unload, change, keeping in repair and position adjustment, using more convenient.
