Abstract
The present invention is a kind of spigot-and-socket penstock installation axial gap locator, be characterized in: it comprises split fixed cover, hasp lock, trip bolt and handle, described split fixed cover forms closed annular by the circular arc body that several radius of curvature are identical, between several circular arc bodies, one sentences that hasp lock is connected, all the other are hinged all successively, split fixed cover arranges several trip bolts along all radial directions, and split fixed cover also arranges at least two handles.Using method is: determine that socket enters the size of bellmouth; Spigot-and-socket penstock installation axial gap locator of the present invention is installed; Carry out spigot-and-socket penstock installation; Take off spigot-and-socket penstock installation axial gap locator of the present invention.
Description
Technical field
The present invention relates to pipeline field, is a kind of spigot-and-socket penstock installation axial gap locator of axial required gap when can control spigot-and-socket penstock installation.
Background technology
Pipeline transportation be with pipeline as the means of transportation of a kind of long distance delivery liquids and gases goods and materials of means of transport, have freight volume large, take up an area less, the pipeline transportation construction period is short, expense is low, pipeline transportation is safe and reliable, continuity is strong, pipeline transportation consumes energy less, cost is low, profitable advantage.Pipe is the main member forming pipeline, pipe has steel pipe, cast iron pipe, concrete reinforced pipe, non-metallic pipe several by material, connected mode has socket joint connection, Flange joint, welding, bonding several, socket joint to connect to be convenient and swift during pipe connects, connected mode safely and efficiently.The pipe that socket joint connects when mounted, need between bellmouth and the axial direction of socket that there is certain gap, to meet the compensation needs expanded with heat and contract with cold of pipe, in the actual installation of the pipe of socket joint connection, because caliber is large, size is long, sealing intensity is large, so power required when installing is larger, and owing to there is certain difference between bellmouth size and socket size, although be beneficial to installation, but be difficult to control the axial gap between bellmouth and socket, during too small the or dieback of axial gap, environment temperature is high, when pipe heat rises, steel pipe can produce to be heaved, there is potential safety hazard, when axial gap is excessive, environment temperature is low, pipe shrinkage time, easily cause again leaking, therefore, the pipe that socket joint connects when mounted, has rational axial gap just important all the more between bellmouth and socket.
Summary of the invention
Technical problem to be solved by this invention is: the shortcoming overcoming prior art, provides that a kind of structure is simple, quick for installation, convenient disassembly, the spigot-and-socket penstock installation axial gap locator of required axial gap when can control spigot-and-socket penstock installation.
The scheme of technical solution problem of the present invention is: a kind of spigot-and-socket penstock installation axial gap locator, it is characterized in that: it comprises split fixed cover, hasp lock, trip bolt and handle, described split fixed cover forms closed annular by the circular arc body that several radius of curvature are identical, between several circular arc bodies, one sentences that hasp lock is connected, all the other are hinged all successively, split fixed cover arranges several trip bolts along all radial directions, and split fixed cover also arranges at least two handles.
Using method of the present invention is:
1) size of bellmouth is entered according to caliber, material, bellmouth size and socket Size calculation determination socket;
2) be starting point by mouth end on the socket external diameter of rear steel pipe, at size stop place, spigot-and-socket penstock installation axial gap locator of the present invention be installed according to the size that step 1) is determined, with hasp lock locking split fixed cover, then fixed with trip bolt;
3) carry out spigot-and-socket penstock installation, the socket of rear steel pipe is inserted in the bellmouth of front steel pipe, until the bellmouth end contact of the spigot-and-socket penstock installation axial gap locator end face of the present invention that rear steel pipe is fixed and front steel pipe;
4) open hasp lock, take off spigot-and-socket penstock installation axial gap locator of the present invention.
Spigot-and-socket penstock installation axial gap locator of the present invention, the hinged structure be connected with hasp lock of several circular arc bodies of split fixed cover can either close as axial gap location when spigot-and-socket penstock installation, hasp lock can be opened again open wide taking-up after spigot-and-socket penstock installation, there is structure simple, reliability is high, quick for installation, repair demolition is convenient, the advantages such as long service life.
Accompanying drawing explanation
Fig. 1 is the schematic front view of spigot-and-socket penstock installation axial gap locator of the present invention;
Fig. 2 is that schematic diagram is looked on a left side of Fig. 1;
Fig. 3 is the structural representation of embodiment.
In figure: 1 split fixed cover, 2 hasp locks, 3 handles, 4 trip bolts, steel pipe before 5, steel pipe after 6.
Detailed description of the invention
Below in conjunction with drawings and Examples, the present invention is further described.
With reference to Fig. 1 ~ Fig. 3, spigot-and-socket penstock installation axial gap locator of the present invention, it comprises split fixed cover 1, hasp lock 2, handle 3 and trip bolt 4, described split fixed cover 1 forms closed annular by the circular arc body that several radius of curvature are identical, between several circular arc bodies, one sentences that hasp lock 2 is connected, all the other are hinged all successively, split fixed cover 1 arranges several trip bolts 4 along all radial directions, and split fixed cover 1 also arranges at least two handles 3.The present invention adopts prior art manufacture, and described hasp lock 2 is the commercially available prod of prior art.
The present embodiment forms closed split fixed cover 1 by the circular arc body that two radius of curvature are identical, and two circular arc body one end adopt that hinge is connected, the other end is connected by hasp lock, and its using method is:
1) size of bellmouth is entered according to caliber, material, bellmouth size and socket Size calculation determination socket;
2) be starting point by mouth end on the socket external diameter of rear steel pipe 6, at size stop place, spigot-and-socket penstock installation axial gap locator of the present invention is installed according to the size that step 1) is determined, lock split fixed cover 1 with hasp lock 2, then fixed with trip bolt 4;
3) carry out spigot-and-socket penstock installation, the socket of rear steel pipe 6 is inserted in the bellmouth of front steel pipe 5, until the bellmouth end contact of the spigot-and-socket penstock installation axial gap locator end face of the present invention that rear steel pipe 6 is fixed and front steel pipe 5;
4) open hasp lock 2, take off spigot-and-socket penstock installation axial gap locator of the present invention.
