Insulating cement design, the disadvantage designed in this way are difficult to dismantle, are difficult to repair when instrument is broken.
Summary of the invention
The utility model will solve the disadvantage that the above-mentioned prior art, provide that a kind of structure is simple, filling type of convenient disassembly
ALPHA SUB instrument.
The utility model solves the technical solution of its technical problem use: the ALPHA SUB instrument of this filling type, mainly
Including mandrel, metal electrode ring and non-metallic insulation ring, metal electrode ring and non-metallic insulation ring are sequentially sleeved in the outside of mandrel,
Metal electrode ring is provided with compressed spring and piston, in the space inside mandrel exterior and metal electrode ring and non-metallic insulation ring
Equipped with hydraulic oil.
The metal electrode ring and non-metallic insulation ring are 2, and metal electrode ring and non-metallic insulation ring are spaced apart from each other
Distribution, the metal electrode ring on top are provided with compressed spring, and the metal electrode ring of lower part is provided with piston.
The upper and lower end face of the non-metallic insulation ring is equipped with O-ring.
Shell is cased on the mandrel, upper shell is located at the top of non-metallic insulation ring, and the lower end of upper shell is equipped with spiral shell
Line ring, upper shell are connected and fixed by screwed ring.
The lower end of the metal electrode ring of the lower part is equipped with lower pipe nipple.
Internal screw thread is equipped in the lower pipe nipple, the lower end of mandrel is equipped with external screw thread, lower to lead between pipe nipple and mandrel
Threaded connection is crossed, is equipped with retainer plate in lower pipe nipple.
The top of the upper shell is equipped with another screwed ring.
The upper end of the mandrel is equipped with protective cap, and the lower end of mandrel is equipped with protection plug.
The utility model has the advantages that: the utility model structure is by split type structure type, so that each portion
Part can be dismantled individually, and simply disassembly assembling mode simplifies the difficulty of operation so that installation and maintenance are quite convenient to,
Reduce the cost of maintenance.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Description of symbols: metal electrode ring 1, non-metallic insulation ring 2, lower pipe nipple 3, Shangguan's shell 4, screwed ring 5, protection
Cap 6, protection plug 7.
Specific embodiment
The utility model is described in further detail with reference to the accompanying drawing:
As shown, the ALPHA SUB instrument of this filling type, mainly include mandrel, metal electrode ring 1 and it is nonmetallic absolutely
Edge ring 2, metal electrode ring 1 and non-metallic insulation ring 2 are sequentially sleeved in the outside of mandrel, and metal electrode ring 1 is provided with compressed spring
And hydraulic oil is equipped in the space inside piston, mandrel exterior and metal electrode ring 1 and non-metallic insulation ring 2.The upper end of mandrel
Equipped with protective cap 6, the lower end of mandrel is equipped with protection plug 7.
Wherein, metal electrode ring 1 and non-metallic insulation ring 2 are 2, and metal electrode ring 1 and non-metallic insulation ring 2 are mutual
It is spaced apart, the metal electrode ring 1 on top is provided with compressed spring, and the metal electrode ring 1 of lower part is provided with piston.It is nonmetallic exhausted
The upper and lower end face of edge ring 2 is equipped with O-ring, plays the role of sealing.
Shell 4 is cased on mandrel, upper shell 4 is located at the top of non-metallic insulation ring 2, and the lower end of upper shell 4 is equipped with spiral shell
Line ring 5, upper shell 4 are connected and fixed by screwed ring 5.The lower end of the metal electrode ring 1 of lower part is equipped with lower pipe nipple 3.Lower termination
Internal screw thread is equipped in pipe 3, the lower end of mandrel is equipped with external screw thread, is connected through a screw thread between lower pipe nipple 3 and mandrel, lower termination
Retainer plate is equipped in pipe 3.
The top of upper shell 4 is equipped with another screwed ring 5, when needing to be cased with other component on mandrel, passes through this spiral shell
Line ring is fixedly connected.When assembly, protective cap 6 is removed, is directly sleeved on mandrel, is connected to a fixed with screwed ring.
When utility model works, pipe nipple 3 is backed out first to compressed spring and applies pretightning force, to generate axial bullet
Power has thus achieved the effect that sealing so that the O-ring of each end face is compressed and deforms.Mandrel exterior and metal electrode
Hydraulic oil is filled in space inside ring 1 and non-metallic insulation ring 2.When external pressure is greater than internal oil pressure, piston is inside
It walks in portion；When external pressure is less than internal oil pressure, piston is walked toward outside.It finally reaches inside and outside flatten to weigh, piston is with regard to stationary
?.
In addition to the implementation, the utility model can also have other embodiments.It is all to use equivalent replacement or equivalent change
The technical solution to be formed is changed, the protection scope of the requires of the utility model is all fallen within.
