Description
Technical field
The present invention relates to a kind of water pump pipeline telescopic joints of butterfly sealing, belong to water pump pipeline installing and dismounting accessory technology neck
Domain.
Background technique
Water pump will first unload the straight tube of water pump during repair demolition, just can be carried out water pump disassembly, but due to water pump
Straight tube and water pump water outlet pipeline installation site it is limited, if then the straight tube of water pump can not dismantle taking-up using direct-connected installation；
In order to solve this problem, one pipeline extension of installation is usually required in the junction of the straight tube of water pump and water pump water outlet pipeline
Section is taken out by the flexible gap for moving it out about 10 millimeters or so of telescopic joint convenient for the straight tube of water pump.It is existing to use
Pipeline expansion joint is using conical tube structure and squeezes sealing (referring to attached drawing 5), and structure is complicated, and cost is high, difficult to install, and its is close
Envelope is sealed using filler and sealing ring by pressing plate and bolt presses, and sealing ring is poorly sealed after filler corrosion, telescopic joint warp
Often there is leakage phenomenon.
Summary of the invention
It is an object of the present invention in view of the above shortcomings of the prior art, provide a kind of using butterfly automatic-sealed, sealing
Performance is good, durable, and structure is simple, and manufacturing price is low, the water pump pipeline telescopic joint of butterfly sealing easy for installation.
The present invention is to realize above-mentioned purpose by the following technical solutions:
A kind of water pump pipeline telescopic joint of butterfly sealing, it is by connection straight tube, bridge piece, connecting flange a, connecting flange b, butterfly
Shape sealing ring, compacting ring and connecting screw are constituted, it is characterised in that: the right end production for connecting straight tube has connecting flange a, connection method
Butterfly sealing ring and compacting ring are housed on the right side of blue a, the left end of bridge piece, which makes, connecting flange b, connecting flange a,
Butterfly sealing ring, compacting ring and connecting flange b are connected and fixed by connecting screw；The butterfly sealing ring and compacting ring pass through
Nut among connecting screw is pressed on the right side of connecting flange a, the left side of bridge piece and the right side of butterfly sealing ring
At a distance of 10~12 millimeters between end face.
The beneficial effect of the present invention compared with prior art is:
The water pump pipeline telescopic joint of butterfly sealing uses butterfly automatic-sealed, and good seal performance is durable.Butterfly sealing ring
There are 10~12 millimeters of spacing between the end face of bridge piece, need to only unclamp the left side the connecting flange b end on bridge piece
The adjusting nut in face, can by there are 10~12 millimeters of flexible spacing the straight tube of water pump is taken out, structure is simple, manufacture
Price is low, and installation, maintenance is convenient.Solves the knot that existing pipeline expansion joint uses Taper Pipe, sealing ring, filler and L-type extrusion ring
Structure stretches, and structure is complicated, telescopic adjustment, difficult to install, close by L-type pressure ring and bolt presses using filler and sealing ring
The problem of envelope, sealing ring is poorly sealed after filler corrosion, and telescopic joint often leaks.

Specific embodiment
The water pump pipeline telescopic joint of butterfly sealing is by connection straight tube 1, bridge piece 2, connecting flange a3, connecting flange
B4, butterfly sealing ring 5, compacting ring 6 and connecting screw 7 are constituted, and the right end production of connection straight tube 1 has connecting flange a3, connection method
Butterfly sealing ring 5 and compacting ring 6 are housed, the left end production of bridge piece 2 has connecting flange b4, connection method on the right side of blue a3
Blue a3, butterfly sealing ring 5, compacting ring 6 and connecting flange b4 are connected and fixed by connecting screw 7；5 He of butterfly sealing ring
Compacting ring 6 is pressed on the right side of connecting flange a3 by the nut among connecting screw 7, the left side of bridge piece 2 with
At a distance of 10~12 millimeters between the right side of butterfly sealing ring 5.
The course of work of the water pump pipeline telescopic joint of butterfly sealing is that, when water pump assembly operation, motor 12 passes through water
The drive water pump 8 of pump shaft 11, which lifts water from straight tube 9, connection straight tube 1, bridge piece 2 and pumping line 10, to flow out, and passes through at this time
Water in water pipe can generate certain pressure, and the thrust above the butterfly sealing ring 5 for the telescopic joint that a diameter is one meter is
785kg(, that is, siphon pressure is 0.5kg square centimeters minimum, and all can be more than generally 0.5kg pressure, and maximum can reach 10kg
Square centimeter, most commonly used pressure is generally 0.5~1.5kg square centimeter), when by connecting straight tube 1 and bridge piece 2
When joining place, the interior flange of butterfly sealing ring 5 is squeezed and deformed expansion by the pressure in water pipe, to the direction of 2 left end of bridge piece
It rolls, (referring to attached drawing 3 and attached drawing 4), and is close to the inner wall of 2 left end of bridge piece, the left side of bridge piece 2 and butterfly is close
10~12 millimeters of gap sealing between the right side of seal 5 apart, and hydraulic pressure more high sealing is tighter；When water pump assembly stops
When machine, the pressure for managing interior water disappears, and the inner ring of butterfly sealing ring 5 resiles under the elastic force effect of itself, that is, guarantees connection
There are the presence of 10~12 millimeters of gap between the left side of bend pipe 2 and the right side of butterfly sealing ring 5, convenient for taking straight tube 9
Out.
The water pump pipeline telescopic joint of butterfly sealing solves existing pipeline expansion joint using Taper Pipe, sealing ring and filler pair
Expansion joint is sealed, seal structure complex, telescopic adjustment, difficult to install, to be also refilled by filler after adjusting every time, is loaded
The corrosion of bad or filler after sealing ring it is poorly sealed, the problem of telescopic joint often leaks.
The above is presently preferred embodiments of the present invention, and the example above explanation not make for the essence of the present invention by content
Limitation in any form, technology of the person of an ordinary skill in the technical field after having read this specification according to the present invention
Essence is to any simple modification or deformation made by the above specific embodiment, and the technology contents possibly also with the disclosure above
The equivalent embodiment of equivalent variations is changed or is modified to, all of which are still within the scope of the technical scheme of the invention, without departing from
The spirit and scope of the invention.
