Introduction: The tight fitting of the outer ring ensures that the outer ring of the seal tube is not affected by the leakage of the outer ring of the tube, and thus ensures that the sealing of the outer ring is not affected by the leakage of the outer ring

Limit Expansion joint Due to the influence of the downward slope of the other side, the pressure and the outer ring of the connecting ring seal the pipe. When the foundation sinks, the pipe can be tilted, and the sealing can be ensured without leakage, so as to achieve the purpose of automatic compensation. Many enterprises in Shanghai and other regions of the expansion joint industry also adopt the family workshop mode, so it is urgent to establish the modern management concept Consciousness of crisis, consciousness of competition and service.
The company's main products have models Rubber joint Waterproof casing Telescopic device Compensator Duckbill valve Pipe support, oil resistant rubber joint, double flange Force transfer joint Reducing rubber joint , air duct compensator, flexible clamp made of Maanshan Iron and Steel Co., Ltd Rubber flexible joint Rubber check valve Screw thread soft joint, shock absorber, butterfly valve, stainless steel Corrugated compensator Spherical compensator, pipeline filter, leak stoppers, flat welding flange and other pipe accessories. The products are widely used in water supply and drainage, sewage treatment plant, power metallurgy, urban construction, petrochemical and other large and medium-sized enterprises. They are designed and produced in strict accordance with the standards. The special specifications and models can be customized according to the needs and requirements of users.
It can reduce the pressure and thrust of the connector (blind plate force) and compensate the pipeline equipment error. The double flange force transfer joint can not absorb the axial displacement. The expansion joint has paid attention to the environmental adaptability of the product in the early stage of design and manufacture. Therefore, the product is sprayed with anti-corrosion coating, which can effectively guarantee the adaptability of the product to the environment in the application process After delivery, environmental salt spray test is conducted to test the anti-corrosion ability and sealing performance of the products, so as to ensure the use needs of users.
After the middle line and elevation adjustment of the installed pipeline are qualified, the effective support angle range of the pipe bottom shall be backfilled with medium coarse sand, and soil or other materials shall not be used for backfilling, because there is a certain gap between the joint accounts of the corrugated expansion mechanism, and it has certain axial and radial displacement Pipe expander It can effectively make up for and reduce the blind pipeline thrust, but also easy to pump, valve installation and maintenance, pipeline installation and operation, expansion joint replacement is actually an ideal matching product.
Until the pool is full and the liquid level control valve is closed, the pressure can not rise. Here, the designer should consider increasing the pump capacity or reducing the diameter of the water pipe. The difference between the two should be at least two grades. For example, if the water pump is changed to DN 100 and the five way water pipe is changed to DN65, the pressure can only exceed 0 at this time. Therefore, the difference between the water pump and the multi-channel water supply pipe should be two grades.
The limit expansion joint is installed in the nut of the pipeline, and the retaining ring is in the gland nut. Due to the influence of the downward slope of the other side, the pressure and the outer ring of the connecting ring, the pipe can be tilted when the foundation sinks, and the sealing is free of leakage, so as to achieve the purpose of automatic compensation. Many enterprises in Shanghai and other regions of the expansion joint industry still adopt the family workshop mode, which is in urgent need of establishing Modern management concept includes market awareness, service awareness, competition awareness, crisis awareness and brand awareness.
