1. The two seem very similar, but their functions are quite different. Stainless steel metal hose, also known as metal hose, pneumatic ball valve and stainless steel hose, has good flexibility, temperature resistance, pressure resistance and corrosion resistance, and is suitable for transmission of steam, water, oil and various industrial gases and other media.
2. The pneumatic ball valve ball is composed of a valve pipe with multiple layers of rubber scraped nylon cord fabric and outer rubber layer in the inner rubber layer and reinforcement layer. The valve materials used vary according to the media, including natural rubber, styrene butadiene rubber, butyl rubber, butyl rubber, EPDM, neoprene rubber, silicon valve, fluorine valve, etc. It has the functions of heat resistance, acid resistance, alkali resistance, corrosion resistance, abrasion resistance, oil resistance, etc. Pneumatic ball valve plays an important role in the movement, thermal expansion absorption and vibration absorption of the pipeline system. The model length and connection mode of pneumatic ball valve shall be in accordance with the user's requirements. When it is cut, milky juice will flow out, which is called latex. The latex will be condensed, washed, shaped and dried to obtain a natural valve.
According to the connection mode, it can be divided into three types: loose flange type, fixed flange type and threaded type; According to the structure, it can be divided into single sphere, double sphere, curved sphere, etc. The tubular valve part is composed of inner and outer rubber, cord fabric and steel ring, which is formed by vulcanization and then loosely combined with metal flange or parallel joint. This product can reduce vibration and noise, and can compensate for thermal expansion and cold contraction caused by temperature changes. It is widely used in various pipeline systems. Shanghai Dongfeng's professional design capability and production technology are integrated with a new operation mode and technical means. The whole business operation is completed mainly through close cooperation between R&D technicians, production technicians, professional sales personnel and after-sales management personnel.
Due to the enhanced production planning and near optimal resource allocation, the company has nearly "zero inventory" management, and the inventory cost of the enterprise has also reached a relatively optimized configuration. The joint is also called pneumatic ball valve, flexible pneumatic ball valve, valve pneumatic ball valve, shock absorber, valve shock absorber, valve expansion joint, etc. Mainly JGD type and KXT type. This product is a tubular valve part composed of inner and outer rubber, cord layer and steel ring, which is vulcanized at high temperature and high pressure and then loosely combined with metal flange or parallel joint.
This product makes use of the advantages of the valve such as high elasticity, high gas resistance, medium resistance, weather resistance and radiation resistance to reduce vibration and noise, and can compensate for thermal expansion and cold contraction caused by temperature changes. It is widely used in various pipeline systems. The pneumatic ball valve is generally composed of inner rubber layer, fabric reinforcement layer (reinforcement layer has multi-layer rubber scraped nylon cord fabric), middle rubber layer, outer rubber layer, end reinforced metal ring or steel wire ring, which is formed by high temperature and high pressure vulcanization and loosely combined with metal flange or parallel joint. This product makes use of the advantages of the valve, such as high elasticity, high air permeability, medium resistance, weather resistance and radiation resistance, which can reduce the vibration and noise of the pipeline and compensate for the expansion and contraction caused by temperature changes. Raw rubber is elastic and lacks the necessary plasticity during processing, so it is not easy to process. In order to improve its plasticity, the raw rubber should be plasticated, so that the mixing agent can be easily evenly dispersed in the raw rubber. At the same time, it helps to improve the permeability of the rubber material into the fiber fabric and the molding fluidity during the calendaring and molding processes. The process of degrading long chain molecules of raw rubber to form plasticity is called plasticizing.
