1. The main function of the gasket is to increase the contact area, reduce the pressure, prevent loosening, and protect the parts and screws.

2. The gasket is a mechanical seal between two objects, which is usually used to prevent the natural thermal expansion and contraction leakage of the pipeline between the two objects due to pressure, corrosion, and natural thermal expansion and contraction. Since machined surfaces cannot be perfect, irregularities can be filled with spacers. Gaskets are usually made of sheet materials such as pads, rubber, silicone rubber.

Metal, cork, felt, neoprene, nitrile rubber.

Fiberglass or plastic polymers (e.g., PTFE.

Gaskets for specific applications may contain asbestos.

What is a gasket? In fact, we often use gaskets in life, don't look at a small gasket, in fact, it plays a big role in life? Gaskets are usually the basic components of the mechanical supporting system with multiple functions.

The role of gaskets of different materials is more or less different? Let's take a look at the gasket with Tuba Rabbit.

The role of the gasket

Some people also call gaskets such gaskets, which are often used to connect components and nuts for fastening. One of the more common is an oval-shaped sheet with a round hole in the middle, which is used to distribute the load on the nut and reduce vibration to spread wear. Gaskets are often used to tighten and stabilize the operation of mechanical equipment.

Gaskets are also used in other places, such as rubber gaskets or silicone gaskets to inform incoming fans and other devices to reduce the effects of vibration.

Material classification of gaskets

Generally speaking, the purpose of the gasket depends on the material itself. The material of the gasket is generally not too hard. Common gasket materials are:

Metals, rubber, silicone rubber, fiberglass, asbestos, and many more. There are many different types of gaskets, but they are usually divided into three categories: non-metallic gaskets, semi-metallic gaskets, and metal gaskets.

Introduction of non-metallic gaskets

Rubber gasket is one of the non-metallic gaskets, the texture of rubber gaskets is relatively soft, the elasticity is also relatively good, and it is easy to cut into different shapes according to different uses. Due to the characteristics of rubber products, rubber gaskets are often used in pipes or containers to seal and stabilize them.

The gasket made of asbestos rubber is also often used, because the gasket made of asbestos rubber can be selected according to the different proportions of different gaskets made of different strength, elasticity and flexibility in suitable places. Usually such gaskets are often used in chemical companies.

Introduction of semi-metallic gaskets

Compared with non-metallic gaskets, semi-metallic gaskets have good flexibility and compressibility, but the difference is that semi-metallic gaskets are not very strong in strength and poor resilience, so they are not suitable for high-pressure and high-temperature places. Semi-metallic gaskets mainly include metal wound gaskets (which are made of metal strips and other alloy materials, graphite and other materials, which are usually used for petroleum, chemical, electric power and other pipelines and valves to seal and stabilize the effect. ), metal tooth profile fitting gasket (usually used in precision machine tools), etc.

Introduction of metal gaskets

The materials used in Jinliangnian gaskets are copper, aluminum, mild steel, stainless steel, etc., and the environment can be at high temperature and high pressure and load comparison. Metal gaskets can be determined according to the shape of the environment: flat metal gaskets, corrugated metal gaskets, and toothed metal gaskets. When choosing, you can choose different forms according to the structural characteristics of the gasket.

The flat metal gasket is made of narrow widths as much as possible.

By introducing the function of gaskets and the gasket materials under different functions, how much do you know about gaskets?

According to its material and structural characteristics, gaskets can be divided into three categories: non-metallic gaskets, metal gaskets, and metal-non-metallic combined gaskets. A gasket is a mechanical seal between two objects, usually used to prevent the leakage of pressure, corrosion, and natural expansion and contraction of pipelines between two objects. <

1. Non-metallic gasket.

Application: There are rubber, asbestos rubber sheet, flexible graphite, PTFE, etc., and the cross-sectional shape is rectangular.

2. Metal composite gasket.

Application: There are all kinds of metal wrapping pads, metal wrapping pads.

3. Metal gasket.

Application: There are metal flat pads, corrugated pads, ring pads, toothed pads, lens pads, triangular pads, double cone rings, C-rings, hollow O-rings, etc.

Gaskets are usually made of sheet materials such as pads, rubber, silicone, metal, cork, felt, neoprene, nitrile, fiberglass, or plastic polymers (such as PTFE). Gaskets for specific applications may contain asbestos.

The types of gaskets include rubber gaskets, metal gaskets, fiber gaskets, and so on.

1. Rubber gasket.

Rubber gaskets are usually made of natural rubber or synthetic rubber. They have good elasticity and abrasion resistance, and are able to withstand large pressure and temperature changes. Rubber gaskets are suitable for use in water pipes, air pipes, oil pipes, and other equipment that requires waterproofing and sealing.

2. Metal gasket.

Metal gaskets can be made of copper, aluminum, stainless steel, or titanium. This kind of gasket has the characteristics of high strength and high temperature resistance of the Jieqing School, and is suitable for equipment and machinery in high pressure and high temperature environments.

3. Fiber gasket.

Fiber gaskets are usually made of asbestos-free, mineral, or organic fibers. They have good chemical resistance and thermal insulation properties, and are commonly used in pipes, valves, pumps, and other equipment that requires corrosion resistance and high temperature resistance.

The role of the gasket

1. Sealing function: gaskets are widely used in various sealing devices, such as pipelines, valves and pumps. It creates a tight seal that prevents fluid or gas leakage by filling and filling the gap between two or more connected parts.

Gasket materials are selected to accommodate different temperatures, pressures, and chemistries depending on the operating environment and medium.

2. Reduce friction: The gasket can reduce the friction between the connecting parts and reduce the wear and tear of the equipment. By forming a thin layer of cushion between the friction surfaces, the gasket can effectively reduce friction and wear, and extend the life of the equipment.

3. Balance clearance: In the assembly process of mechanical equipment, due to processing errors and assembly errors, there is often a gap between connecting parts. Gaskets fill these gaps, guaranteeing proper contact and tight connection between the connecting parts.

It is able to balance and adjust the height difference between different parts, making the assembly more precise and stable.

Gasket thickness standard:

The thickness of the main body t: , the limit deviation is ; The thickness of the reinforcing ring t1: 2mm, the limit deviation.

The thickness of the main body t: , the limit deviation is ; The thickness of the reinforcing ring t1: 3-5mm, the limit deviation is Tanna.

DN<200, gasket body d2 (+ 0mm), d3 (0; Inner and outer rings: d1 (+ 0mm), d4 (0.

The material of the metal gasket is made of original imported stainless steel and high carbon steel.

as well as late brass.

The three materials are made by heat treatment and fine grinding, which has precision.

High, tough, not easy to break. Among them, the material of high-carbon steel has a certain elasticity, and the material of stainless steel is very tough.

Uses of metal gaskets: used in electronic instruments, mold making, precision machinery. Mold maintenance, Xingxin Li mold measurement gap and due to mechanical aging when shaking, swinging and instability, this product can be used to solve the problem of machine maintenance. Flange connection.

The sealing effect is also a great use for metal gaskets.
