What are the models of rubber soft joints, and what are the models and specifications of rubber soft

Here are some of the well-known brands recognized in the rubber soft joints industry, which are widely recognized and have a great reputation. While rankings may vary depending on time and market conditions, the following brands are generally considered to be among the top brands in the valve industry:

The following are the top ten domestic first-line valve brand manufacturers in 2022-2023, but for reference only: Suzhou Neway Valve Co., Ltd., Shanghai Guanlong Valve Machinery, Shanghai Qizhong Valve Manufacturing, Sanhua, Su Yan, Shentong, Su Valve, Nanfang, Jiang.

First, the word Yao. The above manufacturers are only estimates and references, and the specific situation may vary or fluctuate at any time due to changes in a series of factors such as changes in the market, the size of the competition pattern, and the stability of product quality. As an indispensable key device in industrial production and civil facilities, the quality and reputation of the valve brand directly affect the satisfaction and trust of users.

These brands are known in the valve industry for their innovative technology, high-quality products and reliability. It is important to note that the market and industry are evolving rapidly, and different rankings may vary depending on time and region. For the most up-to-date ranking information, it is recommended to refer to industry reports, professional organizations or market research data for more detailed and accurate information.

Is there a national standard for rubber soft joints? Nitrile rubber in the original rubber is prepared by emulsion polymerization of butadiene and acrylonitrile, and nitrile rubber is mainly produced by low-temperature emulsion polymerization, with excellent oil resistance, high wear resistance, good heat resistance and strong adhesion. The more acrylonitrile content, the better the oil resistance, and nitrile rubber is mainly used to make oil-resistant rubber products.

In addition, it also has good water resistance, air tightness and excellent adhesion properties. It is widely used in the production of various oil-resistant rubber products, a variety of oil-resistant gaskets, gaskets, sleeves, flexible packaging, soft rubber tubes, printing and dyeing rubber rollers, cable rubber materials, etc., and has become an indispensable elastic material in the automobile, aviation, petroleum, photocopying and other industries. The disadvantage is that the cost is higher.

Many names are enough to indicate that the rubber soft connection is perfect and has a wide range of applications. Some names are determined according to their own raw materials or the role of their own combustion in the installation range, but some are based on their own specifications and models.

to take the name, such as a single ball rubber soft connection. There are many models, specifications and specifications of rubber soft joints. In the various models, specifications and models of rubber soft connections, in order to better distinguish and identify various different types of rubber soft connections, there are more and more patterns of rubber soft connections, and the models, specifications and sizes are constantly increasing.

In the future, KXT-I, KXT-II and KXT-III will slowly appear in the KXT product line according to the different pressures of the rubber soft connection, but in addition to the pressure, the single ball rubber soft connection will also slowly change the mode to show its powerful effect.

Together with the single-ball rubber soft connection, there is a double-ball rubber soft connection with the specification model KST. The structural characteristics of this rubber soft joint and single ball rubber soft joint have changed a lot. For example, the specifications and models of the anti-pull-off double-ball rubber soft connection are indicated as:

kst-f。Thus, a variety of different kinds are slowly based on transformation. In addition to the above simplicity, there are also many characteristic rubber soft connection specifications and models, such as:

The model specifications are KYP's load-reducer rubber soft connection, KYT's concentric reducer rubber soft connection, and KKT's thread connection.

Operating temperature: -40 degrees to 80 degrees (high temperature resistant rubber soft joints can also be processed).

Rubber joints are widely used, and the corresponding types are also diverse, and different types have different uses and characteristics, but according to the current market sales type, it can generally be divided into 6 types, as follows:

Brother digging potato 1, buckle groove rubber joint.

That is, on the flat welded flange, according to the size of the soft joint ball, a groove can be buckled on the soft joint, which can not only greatly reduce the vibration and noise of the pipeline system, but also fundamentally solve the problems of interface displacement, axial expansion and misalignment of various pipelines.

2. Flanging rubber joints.

Generally designed under high pressure, unlike the buckle groove, the edge of this soft joint covers the part of the flange and a hole is punched in the edge of the rubber.

3. Negative pressure resistant rubber joints.

That is, a steel ring is added to the inner edge of the rubber soft joint to prevent the rubber soft joint from being sucked and deformed at the inlet of the pump due to too much suction.

4. High-pressure resistant rubber joints.

The method of reinforcing rubber is adopted, and steel wire is added to the body of rubber, or other reinforcing materials are added, so that the strength of rubber is increased, so as to resist the impact of high pressure.

5. Anti-pull-off limit rubber joint.

That is, at the edge of the flange, the lug plate with the limit function is welded and hail, and the upper and lower correspond and are passed through with bolts, so as to achieve the limit function.

6. Lined with PTFE rubber joints.

That is, it is used in a medium with high strength corrosiveness, which is higher than the ability of ordinary rubber to withstand.

Generally, there are clamp connections, flange connections, and clamp connections. Rubber ball material: The head ball is composed of a lining layer, a lifting layer, a double-scraped cotton cord, and an outer rubber layer composite chain shed rubber hose.

Natural rubber, styrene-butadiene rubber, butyl rubber, nitrile rubber, EPDM, ternary EPDM, neoprene, silicone, fluorine rubber and so on. They have the functions of high temperature resistance, acid resistance, alkali resistance, corrosion resistance, wear resistance, acid and alkali resistance, etc.

1. Installation of the rubber joint of the thread connection:

Before installation, the two ends of the pipe fittings that need to be connected are flattened on the horizontal plane, and the thread rubber joint is screwed on one of the pipe fittings during installation, and then the other end of the pipe fittings is screwed, which is always kept on the horizontal plane to prevent the uneven force from tearing the rubber ball during the installation process, and then tighten the silk Mingqing Wang buckle with a hand or wrench, and finally fix the silk old buckle rubber joint and the pipe fittings at both ends on the object that is not easy to stretch or twist.

Second, the installation of flange connection rubber joints:

Before the installation of the flange rubber joint, the two ends of the pipe fittings that need to be connected are flattened on the horizontal plane, and the fixed end pipe fittings are flattened during installation, and then the flange on the rubber joint is rotated to align the flange hole around, and then the flange of the other end of the pipe fitting is horizontally aligned with the flange on the rubber joint, and the flange on the rubber joint is rotated to make the flange mouth face to each other, and the screw is screwed on the nut and the three are closely connected in the horizontal direction to prevent the sealing from being tight.

3. Installation of clamp connecting rubber joints:

Clamp rubber joint, using clamp to replace flange and bolt, installation can be the clamp rubber joint of the two nozzles respectively on the pipe to be connected on the pipe to be connected, through the clamp rubber joint and pipeline fixed connection.
