Explosion-proof screwcrew head
Explosion-proof screwing head, also known as hexagon joint, is a necessary supporting tool used to connect the screwing head and the supporting handle, it is combined with the screwing head to form a screwing sleeve, the connection function of the explosion-proof screwing head: connect the screwing head with the handle, so that the two work together, so as to realize the function of tightening or loosening screws, nuts and other tightening fasteners, and reduce the cost of manpower and material resources: the screwing sleeve formed by the combination of the explosion-proof screwing head and the screwing head is lower than the manufacturing cost of the integral screwing sleeve, Improved versatility: Different specifications and types of screwing heads can be used with the same handle through screwing joints, which improves the versatility and efficiency of the tool, and users only need to prepare different explosion-proof screwing heads to adapt to a variety of different shapes and sizes of screws.
According to the material, it can be divided into three categories: carbon steel explosion-proof screwcrew head, alloy steel and stainless steel. The screwing joint made of carbon steel has a low cost and has a certain strength and hardness; The strength, toughness and wear resistance of the screwed joints made of alloy steel, such as chromium vanadium steel (CR-V), are often used to manufacture high-quality screwed joints; The stainless steel screwcrew joint has good corrosion resistance, it is mainly suitable for humid and corrosive environments, and is classified according to the production method: it can be divided into forging and casting.
The forged explosion-proof screwhead joint is processed by forging technology, and its internal structure is tight, with high strength, good toughness and relatively high quality; The cast screwing joint is formed by the casting process, with high production efficiency and low cost, but it may be slightly inferior to forged products in terms of strength and toughness, and is classified according to the connection type: threaded connection, flange connection, quick connection, etc. The application of threaded screwing joints is the most widely used in daily life, and its structure is simple, easy to install, and low price; The sealing performance and reliability of the screwcrew joint connected by the flange are high, and they are often used in some occasions with high requirements for tightness; The quick-connect screwing joint has the characteristics of quick loading and unloading, which can improve work efficiency, and is selected according to the work requirements: according to the type, size and working environment of the screws that need to be tightened or loosened in actual work, the screwing joint with appropriate specifications, types and materials is selected.
Pay attention to matching: ensure that the size and connection mode between the screwing joint and the screwing head and handle are matched to ensure that the connection is firm and reliable, and avoid loosening and slipping during use, and correct use and maintenance: excessive force or improper torque should be avoided when using, so as not to damage the screwing joint or screwing head. Clean up in time after use to avoid impurities such as oil and dust, and store properly to prevent rust and deformation.
FAQ
Q: Why can the explosion-proof screwcrew head be explosion-proof?
A: It is made of non-spark materials such as copper alloy, which is not easy to produce sparks when rubbing or impacting, and cooperates with the explosion-proof design structure to reduce the safety risk in flammable and explosive environments.
Q: What scenarios are applicable?
A: It is suitable for petroleum, chemical, coal mine, natural gas and other dangerous places where combustible gas and dust exist, and is used for tightening/disassembling bolts, nuts and other operations.
Q: How to maintain explosion-proof performance?
A: Avoid collision and scratching with hard objects, clean the oil stain in time after use, store it in a dry environment, and regularly check whether there are cracks or wear on the surface to ensure that the explosion-proof surface is in good condition.
