Description
Technical field
A kind of municipal works irrigation pipeline connection extension fixture of the present invention, is related to one kind in municipal treegarden irrigation, to needing
The flexible pipe to be connected carries out the device of mouth of pipe expansion, belongs to municipal works field.More particularly to one kind in flexible pipe outer wall by setting
Multiple fulcrums are found, the gripping of multiple spot, the device that the mouth of pipe of flexible pipe is expanded are carried out along flexible pipe circumferencial direction.
Background technology
At present, when municipal works are irrigated afforestation, it is necessary to carry out the connection in water route, particularly some big faces
, it is necessary to which water route pipeline is renovated, area is big for long-pending turf greening, and the node of connection is just more, golden using low side is passed through among flexible pipe at present
Category pipe is attached, and is then clamped fixation by steel wire on flexible pipe and metal tube, is sealed by the contraction of flexible pipe,
But in real process, for Hose Jacket at the surface of metal tube, flexible pipe struts difficulty, is easy to pipeline occur when in use
Revealed in link position, or the excessive pipeline of hydraulic pressure disconnects, influence to irrigate the progress of construction, pass through tiny sled when common
Bar, a point of flexible pipe is tilted, it is ridden in metal pipe outer wall, then carrying out prizing for next point, it is final to cause
For Hose Jacket on metal tube, point-by-point prizes expansion, flexible pipe force unbalance, is easy to that section occurs not in process of expansion
Circle, metal tube can not insert, and efficiency is low easy to fall off, and by ripping bar, easily flexible pipe occurs to crush, and influences quality, existing
Using heating flexible pipe, the method by expanding with heat and contract with cold so that hose expansion is expanded, and then directly inserts metal tube in flexible pipe,
After flexible pipe cooling meat, difference packs tightly sealing, it is necessary to extra energy auxiliary by way of i.e. heat in this method, and again
During the cooling meat of flexible pipe, metal tube easily comes off to be packed tightly, it is necessary to could complete connection after waiting for a period of time, connection week
On phase, also have and strutted caliber from inside hose using eyelid retractor, but the insert the distance for strutting rear metal tube is limited, and support
Hold the taking-up difficulty of device or even can stay in flexible pipe, expander in flexible pipe, to causing flexible pipe to deform, influences the logical of current for a long time
Cross, and expander support is deflected in flexible pipe when shifting, the section of flexible pipe can also deform therewith, form irregular shape.
Publication number CN101327645 discloses a kind of device for expanding thermal shrinkage tube, and it includes a dilatation mold, the extension module
Tool includes an overcoat and a sizing tube, and the sizing tube is arranged on the inside of the overcoat, is divided between the overcoat and sizing tube
One vacuum chamber and a cooling chamber, outer put at the cooling chamber offer at least one water inlet and at least one delivery port, should
Dilatation mold also includes several inlet openings being opened on the sizing tube at the cooling chamber, and cooling water can enter by inlet opening
Enter inside sizing tube, the invention device for expanding thermal shrinkage tube is extended by heating body, in fact a body integrated straight
Footpath becomes big process, is not suitable for being directed to the extended operation of oral area under connection, while when after the expansion in the invention not
Reversible, therefore the gap between the body and metal tube after expansion is fixed, and does not have collapsed seal, easy leak or disconnection.
The content of the invention
In order to improve the above situation, a kind of municipal works irrigation pipeline connection extension fixture of the present invention provides one kind and passed through
Multiple fulcrums are set up in flexible pipe outer wall, the gripping of multiple spot is carried out along flexible pipe circumferencial direction, the mouth of pipe of flexible pipe is expanded
Device.
A kind of municipal works irrigation pipeline connection extension fixture of the present invention is realized in：A kind of municipal works of the present invention
Irrigation pipeline connection extension fixture is made up of main body fixing device and extension fixture, and main body fixing device is prevented by expansion arm, arc
Backplate, spacing ring, annular fixing frame, body cradle, magnetic steel bar, actuating arm and folder hook composition, annular fixing frame lateral wall are equidistant
