Description
Technical Field
The utility model relates to a technical field is maintained to the choke valve, especially relates to a dismantle device of choke valve case.
Background
The desulfurization and slagging-off station is an important process for pretreating molten iron produced by a converter in a steel-making part, and most of the molten iron required by the converter steel-making needs to be subjected to desulfurization pretreatment in the process. At present, a ladle transfer station of a steel-making part has three stations and mainly comprises a blowing system and a slag removing system, and the blowing system is the most important. The throat regulating valve is a key device of a blowing system, the interior of the throat regulating valve needs to be regularly cleaned in daily device maintenance because the device is used for regulating calcium oxide and passivating a magnesium desulfurizer, and the disassembly of a valve core of the throat valve is a key link influencing the operation progress. The disassembly resistance of the valve core mainly comes from the friction force of desulfurizer and rubber sealing rings accumulated between the valve core and the valve sleeve, no special tool for disassembling the valve core of the throat valve exists at present, the disassembly operation efficiency for disassembling the valve core of the throat valve is low, and the valve core of the throat valve is easy to damage.
Disclosure of Invention
In order to overcome the defects of the prior art, the utility model provides a device for disassembling the valve core of the throat valve, which can rapidly disassemble the valve core of the throat valve, is convenient for maintenance operation and improves the operation efficiency; the operation intensity of operators is reduced, and the throat valve is prevented from being damaged in the dismounting process.
In order to achieve the above purpose, the utility model adopts the following technical scheme:
a device for disassembling a valve core of a throat valve comprises a handle, a body and a fixing pin; the lower part of the body is provided with a rectangular through hole, and the bottom surface of the rectangular through hole is provided with a threaded through hole; the handle is rod-shaped and is fixedly connected to the top of the body; the fixed pin is the rectangular strip pin corresponding to the groove of the valve core of the detachable throat valve, the width of the fixed pin is less than or equal to the width of the groove of the valve core of the detachable throat valve, and the fixed pin is distributed in two sides at the bottom of the body in the middle.
The handle is a round rod.
The body is a flat rectangular body.
The fixing pin is provided with a chamfer angle of 2-7 degrees.
Compared with the prior art, the beneficial effects of the utility model are that:
the utility model discloses the body middle part is equipped with the rectangle through-hole, and rectangle through-hole bottom surface is equipped with the screw thread through-hole, and the fixed pin is the rectangle rectangular pin corresponding with dismantlement larynx case recess, and the fixed pin distributes in two sides between two parties in the body bottom; when the valve core fixing device is used, the fixing pin is inserted into the groove of the valve core at the throat, and the bolt penetrates through the threaded through hole to fix the valve core. When the valve is operated, the handle is held tightly, and the valve core is pulled and rotated at the same time, so that the friction force of the desulfurizer accumulated between the valve core and the valve sleeve and the rubber sealing ring is overcome, and the valve core is pulled out.
The valve core of the throat valve can be quickly detached by using the utility model, so that the maintenance operation is convenient, and the operation efficiency is improved; the operation intensity of operators is reduced, and the throat valve is prevented from being damaged in the dismounting process.

Detailed Description
The following description of the embodiments of the present invention will be made with reference to the accompanying drawings:
example (b):
as shown in FIGS. 1 to 4, a device for disassembling a valve core of a throat valve comprises a handle 1, a body 2 and a fixing pin 3.
The body 2 is made of alloy steel material, the alloy steel with the thickness of 15mm multiplied by 125mm multiplied by 45mm is integrally formed by machining modes such as turning, drilling, wire cutting and the like, and the body 2 is a flat rectangular body. The middle of the lower part of the body 2 is provided with a rectangular through hole 21 with the diameter of 25mm multiplied by 30mm, and the bottom surface of the rectangular through hole 21 is provided with a thread through hole 22.
A45 mm multiplied by 10mm notch is formed in the center of a seamless steel pipe with the outer diameter of 22mm, the wall thickness of 3mm and the length of 300mm, a handle 1 is manufactured, a body 2 is inserted into the handle 1 through the notch, the handle 1 and the body 2 are welded, and full welding and polishing are carried out.
The fixed pin 3 is the rectangular strip pin corresponding to the groove of the disassembly throat valve core 4, the external dimension is 5mm multiplied by 16.5mm, and the two fixed pins 3 are distributed in two sides in the middle at the bottom of the body 2. The width of the fixing pin 3 is less than or equal to the width of a groove for detaching the valve core 4 of the throat valve. The fixing pin 3 is provided with a chamfer of 5 °.
When the fixing device is used, the fixing pin 3 is inserted into the groove of the valve core 4 of the throat valve, and the bolt 5 is penetrated through the threaded through hole 22 to fix the valve core. When in operation, the handle 1 is held tightly, and is pulled and rotated at the same time, so that the friction force of the desulfurizer accumulated between the valve core 4 and the valve sleeve and the rubber sealing ring is overcome, and the valve core 4 of the throat valve is pulled out.
The valve core 4 of the throat valve can be quickly detached by using the utility model, so that the maintenance operation is convenient, and the operation efficiency is improved; the operation intensity of operators is reduced, and the throat valve is prevented from being damaged in the dismounting process.
