Quick assembling and disassembling type maintenance cylinder for normal pressure thickening instrument
Technical Field
The utility model relates to an oil drilling well cementation grout performance test instrument, in particular to ordinary pressure thickening appearance is with a section of thick bamboo is supported with quick dress formula of tearing open.
Background
The cement slurry atmospheric thickening instrument is one of common devices in well cementation cement slurry assay, generally needs to be maintained in the atmospheric thickening instrument for a certain time before experiments of testing free liquid, API water loss, rheological property and the like of cement slurry, in the cement paste maintenance process, the maintenance cylinder rotates under the drive of a motor of the thickening instrument, the blades in the maintenance cylinder keep a relatively static state, for cement slurries with different stability, partial cement slurries are difficult to settle, while the bottom of the paddle is difficult to stir the settled cement slurries, after cement paste curing is completed, a small amount of cement paste at the bottom of the curing barrel is thickened to cause difficulty in cleaning, the cement paste accumulated after multiple use is solidified into cement stones, and the cement stones accumulated at the bottom are easy to cause abrasion or incapability of using stirring blades in the subsequent curing process of the cement paste.
The maintenance cylinder of the conventional normal-pressure thickening instrument adopts an integrated bottom cover with an annular groove locked by a clamp spring and turned at the edge, the clamp spring is firstly disassembled by the clamp spring pliers when the bottom cover is disassembled, then a long-handle tool is adopted to knock and take out from the inside of the cylinder body of the maintenance cylinder, and the conditions of deformation of the bottom cover and damage of a sealing ring are easily caused in the knocking and taking-out process.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the technical problem that a quick assembly disassembly, convenient to use's ordinary pressure thickening appearance is with quick assembly disassembly formula maintenance section of thick bamboo is provided.
In order to solve the technical problem, the utility model discloses a technical scheme is: the utility model provides a normal pressure thickening appearance is with quick assembly and disassembly formula maintenance section of thick bamboo, including maintenance section of thick bamboo body and bottom, maintenance section of thick bamboo body top is outer along opening there is the potentiometer bayonet socket, maintenance section of thick bamboo body bottom inner wall car has the internal thread, the bottom is circular, bottom top surface center is equipped with the constant head tank, the bottom surface is opened flutedly along a diametric both sides, the diameter of pressing from both sides between two recesses forms the fixture block, both ends above the fixture block are equipped with the preformed hole, the bottom side car has twists the internal screw thread of twist, be located and be equipped with the seal ring groove on the bottom between bottom top surface and the.
The two grooves are two semicircular grooves.
The preformed holes are symmetrically distributed on a circular arc line formed by the two semicircular grooves.
The diameter of the bottom cover top surface circle is slightly smaller than the inner diameter of the curing cylinder body, and the diameter of the bottom cover bottom surface circle is equal to the outer diameter of the curing cylinder body.
Preferably, the bottom cover is 13mm in thickness, and the sealing ring groove is 3mm in width.
The utility model has the advantages that: the bottom cover can be quickly unscrewed in two modes of an adjustable wrench or a special wrench, so that quick disassembly and assembly are realized; the sealing mode between the bottom cover and the curing cylinder adopts double sealing of a sealing ring and threads, so that a good sealing effect is ensured; the threaded connection mode can not cause the damage to the sealing washer at the dismouting in-process.

Detailed Description
In order to make the objects, technical solutions and advantages of the present invention clearer, embodiments of the present invention will be described in detail below with reference to the accompanying drawings.
As shown in fig. 1-5, the utility model discloses a normal pressure thickening appearance is with quick assembly and disassembly formula maintenance section of thick bamboo, including maintenance section of thick bamboo body 1 and bottom 3, maintenance section of thick bamboo body 1 top is outer along opening there is potentiometer bayonet socket 2, maintenance section of thick bamboo body 1 bottom inner wall car has internal thread 10, bottom 3 is circularly, bottom 3 top surface center is equipped with constant head tank 9, bottom 3 bottom surface is opened along a diametric both sides has recess 6, the diameter of pressing from both sides between two recess 6 forms fixture block 5, both ends above fixture block 5 are equipped with preformed hole 4, bottom 3 side car has the external screw thread 7 of twisting internal thread 10, be located and be equipped with seal ring groove 8 on the bottom 3 between bottom 3 top surface and the external screw thread 7.
The two grooves 6 are two semicircular grooves. The preformed holes 4 are symmetrically distributed on a circular arc line formed by two semicircular grooves 6. The diameter of the top circle of the bottom cover 3 is slightly smaller than the inner diameter of the curing cylinder body 1, and the diameter of the bottom circle of the bottom cover 3 is equal to the outer diameter of the curing cylinder body 1.
Preferably, the thickness of the bottom cover 3 is 13mm, and the width of the sealing ring groove 8 is 3 mm.
The utility model discloses a use: before cement paste maintenance, a sealing ring is installed on the bottom cover 3, the bottom cover 3 sleeved with the sealing ring is screwed at the bottom of the maintenance cylinder body 1 and slightly tightened by hand, and then a movable wrench is used for clamping the clamping block 5 or a special wrench is used for clamping the preformed hole 4 and screwing; after the cement scale of the bottom cover 3 affects normal use, the bottom cover 3 is unscrewed and detached by a wrench, and the cement blocks are removed.
While one embodiment of the present invention has been described in detail, the description is only a preferred embodiment of the present invention, and should not be considered as limiting the scope of the present invention. All the equivalent changes and improvements made according to the application scope of the present invention should still fall within the patent coverage of the present invention.
