Description
Technical field
The present invention relates to a kind of test tools more particularly to a kind of fire coupling to seal pressure test frock.
Background technology
Fire coupling refers to for fire hose connection, fire suction hose connection and configuring in fire hydrant, fire pump, fire-fighting
Pump adapter, water knockout drum, water collector, fire-fighting lance and connecting interface in other fire-fighting equipments and various reducers,
The general name of special-shaped interface, boring cover etc..Fire coupling is formed by component combinations such as ontology, rubber ring, the snare of sealing and baffle rings.
It is divided into hermaphroditic coupling, cassette interface, screw-type interface, special-shaped interface according to connection type difference.
Fire coupling feature has：1, facilitate the arbitrary connection between water band, fire fighting truck, fire hydrant, hydraulic giant；2, interface uses
With it is easy for installation quickly.Most of fire extinguishing liquid such as transmittable water, foam and mixed liquor；3, sealing joint effect is good, makes
It is difficult to fall off in the process with dragging.Standard GB/T 12514.1-2005 fire couplings are to the material of this product and other performances
It is required that having carried out detailed regulation, wherein water-pressure sealed experiment and water pressure test for strength requires as follows.
Water-pressure sealed is tested：By the fire coupling specimen clamping linked on water pressure testing board, pours water and exclude sample
Interior air slowly uniformly boosts to 0.3 MPa in 2 min, and 2 min of pressurize checks whether sample has leakage phenomenon.
Then nominal pressure is uniformly slowly boosted to again in 1 min, and 2 min of pressurize, checks whether sample has leakage phenomenon.
Water pressure test for strength：The pressure in sample is slowly uniformly risen into nominal pressure by leakage test mode
1.5 times and 2 min of pressurize, check whether sample has visible deformation or phenomenon of rupture.
It is many to the tooling type of the sealing of fire coupling and the water pressure test at this stage, but be that clamping difficulty is cumbersome mostly,
Sealing effect is bad, it is difficult to ensure the agility of clamping and sealing integrity during entire experiment.
Invention content
The purpose of the present invention is exactly to solve the above-mentioned problems, to provide a kind of fire coupling sealing pressure test frock, it
With good seal performance, it is easily installed advantage.
To achieve the goals above, the present invention adopts the following technical scheme that：
A kind of fire coupling sealing pressure test frock, including it is sleeved on two interior axis of fire coupling both sides, the interior axis
Inside is provided with rubber seal, and the multiple steel balls of setting are uniformly distributed in the interior axis；It is cased with wild card on the outside of the interior axis
Circle, spring is provided between the outer retainer ring and interior axis.
It is provided with axis retainer ring between the outer retainer ring and interior axis.
12 steel balls are uniformly distributed in the interior axis.
One end of one interior axis is provided with air bleeding valve；One end of another interior axis connects with fast interface
It connects.
The operation principle of the present invention is that：The both sides of fire coupling are inserted in respectively in two interior axis, the two of fire coupling
Side outer ring is engaged with rubber seal, so that fire coupling and interior axis is tightly connected, outer retainer ring is pushed to be moved to fire coupling
Dynamic, outer retainer ring extruding is uniformly distributed 12 steel balls in interior axis, and steel ball blocks the protrusion of the shaft end on the outside of fire coupling, connection
It completes；Fire coupling one end that both sides are cased with interior axis is water inlet end, and one end is water outlet；When carrying out water-pressure sealed experiment, lead to
It crosses fast interface to connect with experimental facilities, opens air bleeding valve, carry out pour water exhaust and pressure experiment.
Beneficial effects of the present invention：Clamping of the present invention is simple to operation, and sealing effect is good, can ensure to test entirely
The agility of clamping and sealing integrity in journey；Axis is internally provided with rubber seal in the present invention, make fire coupling and
Interior axis is tightly connected.

Specific implementation mode
The invention will be further described with embodiment below in conjunction with the accompanying drawings.
As depicted in figs. 1 and 2, a kind of fire coupling seals pressure test frock, including is sleeved on the two of 4 both sides of fire coupling
A interior axis 2,2 inside of interior axis are provided with rubber seal 7,12 steel balls 8 of setting are uniformly distributed in interior axis 2；Interior axis 2
Outside is cased with wild card circle 3, and spring 6 is provided between the outer retainer ring 3 and interior axis 2, is arranged between outer retainer ring 3 and interior axis 2
There are axis retainer ring 9, one end of an interior axis 2 to be provided with air bleeding valve 1；One end of another interior axis 2 connects with fast interface 5
It connects.
The operation principle of the present invention is that：The both sides of fire coupling 4 are inserted in respectively in two interior axis 2, fire coupling 4
Both sides outer ring is engaged with rubber seal 7, so that fire coupling 4 and interior axis 2 is tightly connected, pushes outer retainer ring 3 to fire-fighting
Interface 4 moves, and the extruding of outer retainer ring 3 is uniformly distributed 12 steel balls 8 in interior axis 2, and steel ball 8 blocks 4 outside of fire coupling
Shaft end protrusion, connection are completed；4 one end of fire coupling that both sides are cased with interior axis 2 is water inlet end, and one end is water outlet.
When carrying out water-pressure sealed experiment, it is connect with experimental facilities by fast interface 5, pours water and exclude in testing equipment
Air slowly uniformly boosts to 0.3 MPa in 2 min, and whether 2 min of pressurize, checking experiment equipment has leakage phenomenon,
Then nominal pressure is uniformly slowly boosted to again in 1 min, and whether 2 min of pressurize, checkout facility equipment have leakage
Phenomenon.
Water pressure test for strength：The pressure in experimental facilities is slowly uniformly risen into nominal pressure by leakage test mode
1.5 times and 2 min of pressurize, whether checking experiment equipment have visible deformation or phenomenon of rupture.
Above-mentioned, although the foregoing specific embodiments of the present invention is described with reference to the accompanying drawings, not protects model to the present invention
The limitation enclosed, those skilled in the art should understand that, based on the technical solutions of the present invention, those skilled in the art are not
