Description
Technical Field
The utility model relates to check valve detects dismantlement frock.
Background
In the well cementation and fracturing operation, the check valve is used for conveying fluid media in a single direction, and after the check valve in service is used for a period of time, disassembly detection and part replacement are needed to ensure that the check valve can be continuously in service. When dismantling the check valve more than 3 cun, because of the check valve external contact surface is the arc, if clamping-force is not enough, dismantle frock and check valve contact position and easily skid, do not have the extracting tool who is more suitable and stereotype at present. Meanwhile, after the one-way valve is used for a period of time, the threaded connection part is easy to corrode and rust, and the conveying medium possibly contains sand, so that the clamping is very easy to block during disassembly, the disassembly difficulty is increased, and the efficiency is low.
Disclosure of Invention
An object of the utility model is to provide a well cementation, fracturing operation are with check valve detection dismantlement frock, this frock multiplicable clamping-force to the check valve, are convenient for dismantle not unidimensional check valve, and dismantle efficiently.
In order to achieve the above purpose, the technical scheme of the utility model is that:
a check valve detecting and disassembling tool for well cementation and fracturing operation comprises a main body part, a hard alloy block and a locking mechanism, wherein the main body part is formed into a whole by a circular ring and a handle, the circular ring of the main body part is provided with a plurality of threaded holes, and the locking mechanism penetrates through the threaded holes to be in threaded connection with the circular ring; the inner wall of the circular ring is provided with an open slot, and the hard alloy block is arranged in the open slot and is higher than the surface of the open slot.
The locking mechanism consists of a fastening bolt, a locking nut and a gasket, the locking nut is connected to the fastening bolt, the gasket is sleeved in the fastening bolt, and the tail end of the fastening bolt penetrates through the threaded hole to be in threaded connection with the circular ring.
The open slot is arranged at the joint of the circular ring and the handle.
The hard alloy block is made of CrMo steel.
The utility model discloses an actively the effect does: the tool can adapt to check valves of different specifications through rings of different inner diameters; and compress tightly on the check valve through carbide and a plurality of bolt, the stress point equipartition increases the locking force of frock to the check valve, can dismantle the check valve that is greater than 3 cun bores smoothly, to the especially serious check valve of corrosion, can directly strike main part handle, applys torsional force to main part ring, improves dismantlement efficiency.
Drawings
FIG. 1 is a schematic structural view of the present invention;
fig. 2 is a usage state diagram of the present invention.
Detailed Description
The invention will be further described with reference to the accompanying figures 1-2.
Referring to fig. 1-2, the utility model comprises a main body 1, a hard alloy block 2 and a locking mechanism, wherein the locking mechanism is composed of a gasket 3, a locking nut 4 and a fastening bolt 5. The main body 1 is formed by a circular ring and a handle, and the thickness of the handle is required to be large enough, and the thickness of the handle is generally more than 20mm, so that the main body 1 is ensured to be smash-proof. A plurality of threaded holes are formed in the main body part 1, the locking nut 4 is connected to the fastening bolt 5, the gasket 3 is sleeved into the fastening bolt 5, and the tail end of the fastening bolt 5 penetrates through the threaded holes and the circular ring threaded connection in the circular ring 1 between the main bodies to lock the one-way valve. Through screwing up lock nut 4, prevent that tightly decide bolt 5 is not hard up, installation gasket 3 between lock nut 4 and main part 1 improves lock nut 4's wearability. The inner wall of the circular ring of the main body part 1 is provided with an open slot, and the hard alloy block 2 is arranged in the open slot and is higher than the surface of the open slot. When in use, the hard alloy block 2 is extruded between the open slot of the main body part 1 and the one-way valve to lock the one-way valve; the hard alloy block 2 needs to be wear-resistant, has enough strength and hardness, and can not be lower than a check valve, and can be made of CrMo steel. The number of the locking mechanisms can be set to be more than 1, and the optimal effect is 3. The open slot can be arranged at any position on the circular ring, and is optimally arranged at the joint of the handle and the circular ring.
When the one-way valve works, the union joint on the one-way valve outlet valve body 7 is fixed on a clamp platform, or the one-way valve outlet valve body 7 is fixed in other modes, the working main body piece 1 penetrates through the one-way valve inlet valve body 6, the hard alloy block 2 is placed between the open slot of the main body piece 1 and the one-way valve, the fastening bolt 5 is screwed, and then the locking nut 4 is screwed to prevent the fastening bolt 5 from loosening. The hard alloy block 2 and a plurality of fastening bolts 5 are tightly pressed on the one-way valve, stress points are uniformly distributed, the one-way valve is tightly clamped in the main body part 1, torque force is applied to a handle of the main body part 1, and connecting threads between the inlet valve body 6 and the outlet valve body 7 of the one-way valve are loosened. For the check valve with serious corrosion, the handle of the main body part can be directly knocked to finish the disassembly.
During operation, the inlet valve body 6 of the one-way valve can be fixed and can be detached in a mode that the hard alloy block 2 and the fastening bolt 5 are pressed on the surface of the outlet valve body 7 of the one-way valve.
