65mm, 65-70mm, 70-75mm, 75-80mm, 80-85mm, 85-90mm, 90-95mm or 95-100mm.
Also, body internal thread is provided with the inner surface of big orifice centre bore 11, and in the outer surface of bridging plug joint 2
On be provided with joint external screw thread, by the body internal thread with joint is externally threaded is used cooperatively so that the screw thread of bridging plug joint 2 connects
It is connected in big orifice centre bore 11, realizes the bolt connection of bridging plug body 1 and bridging plug joint 2.
And there is connector center hole 21 in the inside of bridging plug joint 2, and the internal diameter in connector center hole 21 is less than big orifice
The internal diameter of centre bore 11, and the big I of internal diameter in connector center hole 21 is set with specific reference to the size of big orifice centre bore 11
Put.
Joint internal thread is provided with the inner surface in heart hole 21 within a fitting, and is set on the outer surface of stopper component 3
Have stopper external screw thread, by the joint internal thread with stopper is externally threaded is used cooperatively so that stopper component 3, which is threaded in, to be connect
In head centre bore 21, the threaded connection of bridging plug joint 2 and stopper component 3 is realized.
Simultaneously as stopper component 3 is threaded in bridging plug joint 2, therefore, connect in bridging plug body 1 and bridging plug joint 2
After connecing, stopper part 3 is placed on the inside of bridging plug body 1 and bridging plug joint 2.
Further, also there is stopper centre bore 31 in the inside of stopper part 3, and the stopper centre bore 31 is trapezoidal knot
Structure, specifically, stopper centre bore 31 towards big orifice centre bore 11 side internal diameter than it towards connector center hole 21 one
Side internal diameter is big, meanwhile, the most wide internal diameter of stopper centre bore 31 is less than the internal diameter in connector center hole 21.
And stopper boss 32 is additionally provided with the outer surface of stopper component 3, and the external diameter of stopper boss 32 be more than connect

The part changed, additionally it is possible to carry out the operations such as convenient maintenance, realize that bridging plug makes full use of, will not waste.
By the contact with bridging plug joint 2 of pressure break ball, so as to pass through the joint connector center of pressure break ball blocked bridge plug joint 2
Hole 21, and then make it that the big orifice inside bridging plug is blocked.
Meanwhile the upper surface of bridging plug joint 2 is provided with the spherical concave surface being used cooperatively with pressure break ball, will pass through the spherical female
Face so that bridging plug joint 2 and pressure break ball can be more bonded, and the closure in connector center hole 21 is more effective.And spherical
Rubber layer 22 can be also further covered on concave surface, because rubber has anti-skidding characteristic, then when pressure break ball and spherical concave surface connect
After touch, due to the setting of rubber layer 22, additionally it is possible to prevent the slip of pressure break ball, and further seal nipple centre bore 21.
Further, pin-and-hole can be provided with bridging plug body 1, the pin-and-hole runs through bridging plug body 1, and pin-and-hole is arranged at bridge
Fill in the bottom of body internal thread on body 1.Meanwhile through hole is also provided with the stopper boss 32 of stopper part 3, even
After connecting bridging plug, by the way that pin portion is run through into pin-and-hole and through hole, stopper part 3 and bridging plug body 1 are further fixed with this,
Prevent that the flow inside bridging plug is excessive so that pressure damage bridging plug internal structure.
Further, the internal diameter of through hole can be more than the internal diameter of pin-and-hole.
Further, pin-and-hole also can be only set, and be not provided with through hole, then the pin-and-hole is not intended to fix stopper part
3 and bridging plug body 1, but due to the setting of pin-and-hole, the liquid of bridging plug internal flow can will be discharged in bridging plug by pin-and-hole
Portion, prevent inside bridging plug because stopper component 3 causes internal pressure excessive.
And upper slipses 13, lower slipses 14 and packing element 12 are additionally provided with the outer surface of bridging plug body 1；And packing element 12 is fixed
Be connected to the middle part of the outer surface of bridging plug body 1, upper slipses 13 and lower slipses 14 connect respectively the outer surface of bridging plug body 1 top and
Bottom so that upper slipses 13 and lower slipses 14 are respectively placed in the upper side and lower side of packing element 12.
The specific working method of bridging plug body 1 is directed to, it is identical with the setting mode of existing bridging plug, here no longer
Repeated.
Combined type pitching bridging plug of the present utility model has the advantages of rational in infrastructure, easy to use, by inside bridging plug
Big orifice through hole is set, prevents bridging plug from blocking, and the bolt connection by bridging plug joint, bridging plug body and stopper component, side
Just dismantle, so as to which quick-replaceable part could not be reached when bridging plug goes wrong, and realize maintenance, prevent the waste of equipment, meanwhile,
