Description

Technical Field

[0001] The utility model belongs to the technical field of body extraction devices, in particular to a strong magnetic valve extractor. Background Art

[0002] Cementing and fracturing pumps are commonly used in cementing and fracturing operations in oil and gas fields. The valve body used in the pump is a wearing part and is frequently replaced at the site of use. Because the valve body is installed in a liquid cylinder, the internal space of the liquid cylinder is small. When replacing the valve body, one usually pinches the protrusion on the upper part of the valve body with one's fingers and lifts the valve body upward. A small-sized valve body is light in weight and can be lifted out by relying on the strength of one's fingers. However, with the popularization of high-power plunger pumps, the size of valve bodies is getting larger and larger, and the weight is also increasing. For example, 5-inch, 5.5-inch and 6-inch valve bodies all weigh more than 3 kilograms. The space inside the liquid cylinder is small, and it is difficult to remove the valve body by relying on the traditional strength of fingers. Therefore, it is necessary to use tools to remove the valve body. The applicant has designed a tool specifically for removing the valve body, but it is necessary to remove the valve body (structure such as Figure 2 It can only be used if there is a groove on it, such as Figure 2 The 7-1 position.

[0003] However, the valve bodies used on site were designed by different manufacturers, and some manufacturers did not have this groove, so the original design tool could not meet customer needs. Utility Model Content

[0006] A strong magnetic valve remover includes a screw rod, a handle, a strong magnet, a magnetic protective sheet, a shell and a copper sleeve. The shell is a cylindrical structure with one end open. The strong magnet and the copper sleeve are placed inside the shell. The copper sleeve is sleeved on the outer wall of the strong magnet. The magnetic protective sheet is adsorbed on the open end of the shell by magnetic force and can cover the opening of the shell. One end of the screw rod is connected to the handle, and the other end is connected to the non-open end of the shell. The screw rod and the handle are arranged vertically.

[0007] As a specific implementation scheme, the screw rod is in the shape of a steel rod, one end of which is threaded for connecting to the housing, and the other end is a smooth rod for connecting to the handle.

[0008] As a specific implementation scheme, the handle is a steel rod with a hole in the middle. The hole in the middle is used for the screw rod to pass through and be firmly welded. The handle is used to facilitate lifting tools and valve bodies.

[0009] As a specific implementation scheme, the strong magnet is a cylindrical strong magnetic material used to adsorb the valve body.

[0010] As a specific implementation scheme, the magnetic protection sheet is in the shape of a steel disc, which covers the strong magnet when the tool is not in use to protect the strong magnet and prevent the strong magnet from being attracted to other objects.

[0011] As a specific implementation scheme, the non-open end of the housing is threaded for connecting a lead screw.

[0012] As a specific implementation scheme, the copper sleeve is in the shape of a ring, the outer diameter of which is smaller than the inner diameter of the shell, and the inner diameter of which is larger than the outer diameter of the strong magnet.

[0014] Beneficial effects: Compared with the prior art, the strong magnetic valve remover of the utility model solves the problem that the valve body is difficult to remove, and solves the problem that there is no groove on the valve body and the clamp-type valve body removal tool cannot be used. The valve remover of the utility model is a universal tool that can be used to remove the valve body of cementing fracturing pumps and other devices. It has a wide range of applications and can be used for valve bodies of all steel materials. It has a simple design and low cost. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] The present invention will be further described below with reference to the accompanying drawings.

[0020] Example

[0021] A strong magnetic valve remover, such as Figure 1 As shown, it includes a screw rod 1, a handle 2, a strong magnet 3, a magnetic protection sheet 4, a shell 5 and a copper sleeve 6. The shell 5 is a cylindrical structure with an open end. The strong magnet 3 and the copper sleeve 6 are placed inside the shell 5. The copper sleeve 6 is sleeved on the outer wall of the strong magnet 3. The magnetic protection sheet 4 is adsorbed on the open end of the shell 5 by magnetic force and can cover the opening of the shell 5; one end of the screw rod 1 is connected to the handle 2, and the other end is connected to the non-open end of the shell 5. The screw rod 1 and the handle 2 are arranged vertically.

[0022] The specific design and function of each part are as follows:

[0023] The screw rod 1 is a steel rod with one end having a thread for connecting to the housing 5 and the other end being a smooth rod for passing through the hole of the handle 2 and being welded firmly.

[0024] The handle 2 is a steel rod with a hole in the middle. The hole in the middle is used for the screw rod 1 to pass through and be firmly welded. The handle 2 is used to facilitate lifting tools and the valve body.

[0025] The strong magnet 3 is a cylindrical strong magnetic material used for adsorbing the valve body.

[0026] The magnetic protection sheet 4 is a steel disc and covers the strong magnet 3 when the tool is not in use to protect the strong magnet 3 and prevent the strong magnet from being attracted to other objects.

[0027] The non-open end of the housing 5 is threaded for connecting with the screw rod 1 .

[0028] The copper sleeve 6 is in a circular shape, with an outer diameter smaller than the inner diameter of the shell 5 and capable of being placed in the shell 5 , and an inner diameter larger than the outer diameter of the strong magnet 3 and capable of being placed in the strong magnet 3 .

[0029] Tool installation order:

[0030] Insert one end of the screw rod 1 into the hole of the handle 2 and weld it firmly;

[0031] Connect the other end of the screw rod 1 to the housing 5 with a thread;

[0032] Cold-fit the copper sleeve 6 into the housing 5;

[0033] Place the strong magnet 3 into the copper sleeve 6 with a clearance fit, and the strong magnet 3 will be attracted to the bottom of the shell 5;

[0034] Suck the magnetic protection sheet 4 onto the strong magnet 3 from the side, slide it to the center along the cylindrical end surface of the shell 5 to protect the strong magnet 3. When in use, push it outward from the side to remove the magnetic protection sheet 4.

[0035] The process of removing the cementing fracturing pump valve body using the above-mentioned strong magnetic valve remover is as follows:

[0036] The first step is to push the magnetic protection sheet 4 of the strong magnetic valve remover outward from the side to remove the magnetic protection sheet 4.

[0037] Step 2: Hold the handle 2 with your hand and extend the tool vertically downward into the cylinder cavity, being careful not to touch the inner wall of the cylinder;

[0038] The third step is to bring the end face of the strong magnet 3 and the shell 5 close to the middle of the valve body 7, which will attract the valve body. If the valve body has a middle convex head, it is best to attract the middle convex head position to ensure balance;

[0039] Step 4: lift the valve body 7 upwards;

[0040] Step 5: After the valve body is raised, push the valve body 7 to the side to separate the strong magnetic valve remover;

[0041] The working state of the strong magnetic valve taking device of the utility model is as follows Figure 3 As shown, the position of the cementing fracturing pump valve body in the cylinder is as follows Figure 4 shown.
