What is the difference between a three ball rubber joint and a double ball rubber joint?

Rubber joints are available in single, double, triple and quadruple spheres.

Single-ball rubber joints mainly use the unique properties of rubber, such as high elasticity, high air tightness, medium resistance and radiation resistance, the use of high strength, strong cold and hot stability of polyester cord obliquely crossed with it, by high pressure, high temperature molding cross-linking, high internal density, can withstand high pressure, excellent elastic deformation effect, product structure design end arc high, long curve, with a large number of displacement functions, especially used in complex geological conditions, Places with large settlement and frequent cold and heat changes in the pipeline movement are easy to cause pipeline damage. The use of rubber elastic sliding displacement and deformation mechanism force heat transfer function to effectively eliminate the displacement of the pump, valve and pipeline itself physical damage, because rubber is a poor conductive material, so it is a good to reduce vibration and bath sound transmission of the ideal environmental protection products, single ball rubber soft joint, the product design inner wall is smooth, after actual testing, the flow rate of the medium has no impact, and never rust, can basically be exempted from maintenance during the effective operation period.

The double ball rubber joint, the connection method of the flanges on both sides of the pipeline, can be connected with the valve when installed on the pipeline, which mainly plays a role in compensating for the shrinkage of the pipeline and reducing the damage caused by the vibration of the pipeline to other equipment, and is mostly used in the pump room and the pipeline with severe vibration. For high-rise water supply products above DN200, there must be a fixed bracket or an anti-pull-off device. The product is made of a combination of inner and outer rubber and a corrugated soft sleeve molded with a reinforced layer molded vulcanized and a metal flat union.

It is resistant to high pressure, anti-aging, large amount of deflection, excellent elasticity, strong shock absorption ability, extremely easy to install, and is suitable for the import connection of air conditioning fan coil unit of hotel, restaurant guest room and family.

Three-ball rubber joints and four-ball rubber joints have the characteristics of high pressure resistance, heat resistance, aging resistance, good elasticity, large displacement, easy installation, and significant shock absorption and noise reduction effects, and can be widely used in water supply, drainage, water pumps, HVAC, air conditioning, fans, compressors, ships, chemicals, pharmaceuticals, papermaking and other pipeline systems.

The trisphere has one more layer than the double sphere, and the length will be longer than that of the double sphere;

Rubber joints due to the connection of products or metal bellows environmental temperature changes very large, the use of a kind of security system, is a pump, globe valve, pipeline equipment connection of new products, according to the full screw to connect them to each other, so that it becomes a whole, and has a certain offset, convenient and quick assembly.

In the process of assembly and code cavity maintenance, the internal structure of the rubber joint can be adjusted according to the on-site assembly specifications and models, and the internal structure of the rubber joint also has rubber rings and the like, and the flange inner wire is flushed directly, and there are complete sets of equipment for sale, and it can also be processed by itself, which is suitable for the pipeline with shock absorption, such as the pipeline of the centrifugal delay judgment water pump when passing through the wall. If only the pipe passes through the wall, the waterproofing of both sides of the wall and the movement deformation of the pipe can be used.

The flexible single sphere rubber joint is referred to as the rubber joint, and the rubber soft joint is composed of a fabric-reinforced rubber part and a flat union joint, a metal flange of a loose sleeve or a dust spike flange of a threaded pipe, which is used for pipeline vibration isolation and noise reduction and compensation of displacement. It is a pipe joint with high elasticity, high air tightness, medium resistance and Qihong weather resistance.

Single Ball Rubber Fitting is a pipe connector with high elasticity, high air tightness and weather resistance. Installed on the pipeline can reduce the noise generated by vibration of pipelines, pumps and other equipment, and has a strong effect of absorbing vibration. It is widely used in water supply and drainage, circulating water, HVAC, fire protection, papermaking, pharmaceutical, petrochemical, shipbuilding, water pumps, compressors, fans and other pipeline systems.

Structural characteristics of single-ball grinding mold rubber joints:

1.It adopts a multi-layer spherical structure, which has strong vibration absorption ability and good shock absorption and noise reduction effect;

2. It can withstand higher working pressure, greater explosion-proof force, and good flexibility;

3.It can play a good role in compensating for compression, tensile and torsional deformation.

Performance characteristics of single ball rubber joints:

1.The raw materials are good. The use of high-quality rubbers and formulations achieves optimal results in terms of strength and aging.

2.Single-ball rubber joint process design. The product structure package code contains a reinforcing layer and an anti-pull-off steel wire to ensure a safe and blind posture for use.

3.Stress test. The soft rubber joints have passed the pressure test of times, and their elongation, compression, lateral and angular displacements have reached the standard, and have passed the burst test, up to 10 times the burst pressure.

Both single ball rubber soft joints and double ball rubber soft joints are used for flexible connections between metal pipes and hollow rubber products. The inner and outer layers of rubber, the cord layer and the steel ring are made up of tubular rubber parts. Flanges or parallel joints are loosely combined.

The only difference between them is that for a single ball, there is only one rubber ball between the metal tubes, while a double ball means that there are two shapes, hence what are the characteristics of this different structure.

Features of Single Ball Rubber Soft Joints:

1.Reduced vibration and noise;

2.With the increase of temperature, the single ball rubber soft joint will have the effect of thermal expansion and cold contraction;

3.Generally suitable for all kinds of piping systems.

Features of Double Ball Rubber Soft Joints:

1.With the characteristics of all individual balls. In fact, single or double balls are used in the same place, not to mention their differences, in fact, from the advantage of their shape characteristics, the inferior double ball is longer than the single ball, and therefore the amount of compensation and offset is large.

The angles are relatively large. Due to the length of the single ball, the safety type is higher than the double ball. When the intensity is too high, only a single ball can be used, because if a double ball is used, the ball will deform and break!

The rubber joints installed at the inlet and outlet of the pump are mainly to absorb the vibration and noise of the pipeline.

The difference lies in the length of the product, axial and radial displacement, as well as angular displacement, etc.

This is a single ball. This is a double ball.

Flexible rubber joints, high-pressure rubber joints, rubber shock absorbers, compensators, etc. According to the connection method, there are three types: loose flange type, fixed flange type and threaded type. According to the structure, it can be divided into 5 types: single ball, double ball, reducer, curved ball and wind pressure coil.

The double ball rubber joint is composed of the inner and outer layers of the rubber, the cord layer and the steel ring. It is a tubular rubber part that is formed by vulcanization and then combined with a metal flange or parallel joint.
