Soft rubber connector with thread
The threaded rubber joint ball is composed of a rubber tube with an inner rubber layer, a reinforced layer with multiple scraped nylon cord fabrics, and an outer rubber layer. It solves the problem of easy leakage caused by traditional rubber nozzles due to poor interchangeability and poor sealing, and it is safer and more reliable to use. At the same time, connection elements of different materials can be selected according to different conditions of use, and the scope of application is wider. Suitable for water, oil, air, etc., it is the best product for pipeline inlet and outlet connection.

The ball made of non-woven rubber joint is composed of a rubber tube with an inner rubber layer, a reinforced layer with multiple scraped nylon cord fabrics, and an outer rubber layer. The rubber materials used are different according to different media, such as natural rubber, styrene-butadiene rubber, butyl rubber, nitrile rubber, EPDM rubber, neoprene rubber, silicone rubber, fluorine rubber and so on. With heat resistance, acid and alkali resistance, corrosion resistance, wear resistance, oil resistance and other functions. This product has the characteristics of high pressure resistance, good elasticity, large deflection displacement, aging resistance, easy installation, strong selectivity, and good shock absorption.
1. High internal density, can withstand high pressure, good elastic deformation effect.
2, reduce vibration, reduce noise, good scalability, easy to use.
3. It is a pipe joint with high elasticity, high air tightness, medium resistance and weather resistance. Silk-button rubber soft joints take advantage of rubber's elasticity, high air-tightness, medium resistance, weather resistance and radiation resistance. After the polyester cord fabric with high strength, strong heat and heat stability is diagonally compounded, After high pressure and high temperature mold vulcanization.
Product applicable media:
Sea water, fresh water, hot and cold water, drinking water, domestic sewage, crude oil, fuel oil, lubricating oil, refined oil, air, gas, steam and granular powder.
Product application range:
Due to the good overall performance of Hengzhong Silk-Lock Rubber Joints , it is mainly used for the lifting and transportation of raw water and sewage, feed water and cooling circulating water for thermal power plants, metallurgical industry, condensate water, pipeline transportation of chemicals in chemical industry, petrochemical Cooling, dilution and flexible connections between long and short distance pipelines in other industries. Because rubber has high abrasion resistance, it is also suitable for conveying granular and powdery materials and vapors in all industries.
Excellent, threaded (optional) rubber soft joints must be selected according to the working pressure of the pipeline, connection method, medium and compensation amount, and the number is selected according to noise reduction displacement requirements.
Second, when the installation pipeline produces transient pressure and is greater than the working pressure, a joint higher than the working pressure should be selected. (For example, when the instantaneous pressure at the start of the pipeline is greater than 1.0MPa, a joint working at 1.6MPa should be used. When the instantaneous pressure is greater than 1.6MPa, a 2.5MPa joint should be used.)
Third, when the soft joints made of rubber thread buckle are used at the inlet and outlet of the pump, they should be located near the pump side, and metal reducing joints should be installed between the pump and the large diameter reducer.
Fourthly, when the pipe medium of the non-threaded rubber soft joint is acid-base, oil, high temperature and other special materials, a joint that is one gear higher than the working pressure of the pipe should be selected.
Fifth, the flange of the soft joint made of rubber thread should be a valve flange or a flange conforming to GB / T9115.1 (RF).
Sixth, the normal applicable medium is ordinary water at a temperature of 0-60 ° C. Special media such as oil, acid and alkali, high temperature and other corrosive and hard textures should use the corresponding special resistant soft rubber connection. Do not use it blindly or universally.
Seventh, when the displacement of the pipeline is ≥ the maximum compensation amount of the soft rubber connection, the number of joints should be increased to parallel the displacement. It is strictly forbidden to adjust the excess of the pipeline to make the joint in the extreme disturbance displacement and deviation state, and not to exceed Limits (telescopic, displacement, deflection, etc.).
Eighth, the high-level water supply or suspended water supply uses a soft rubber connection. The pipeline should be fixed on a hanger, bracket or anchor, and the joint cannot bear the weight and axial force of the pipeline. Otherwise, the joint should be equipped with anti-pulling device (its The bearing force must be greater than the axial force of the pipeline).
When the medium passed by Hengzhong Pipe is made of non-threaded rubber soft joint, the medium passing through is acid-base, oil, high temperature and other special materials. The joint should be selected by a gear higher than the working pressure of the pipe, and it also has the characteristics of noise reduction displacement. .
