Electric ball valve can also be called flexible electric ball valve, electric ball valve, electric ball valve, flexible electric ball valve, valve expansion joint, electric ball valve, shock absorber, etc. It is a pipe connector with high elasticity, high air tightness, medium resistance and weather resistance. The electric ball valve is generally composed of an inner rubber layer, a fabric reinforcement layer (the reinforcement layer has multiple layers of rubber scraped nylon cord fabric), a middle rubber layer, an outer rubber layer, an end reinforced metal ring or a steel ring, which is formed by vulcanization at high temperature and pressure, and loosely combined with a metal flange or a 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.
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.
The electric ball valve of the valve is generally installed in places where there is vibration in the pipeline operation or the axial expansion of the pipeline due to the impact of thermal stress in long-distance pipeline transportation. In the face of problems arising from the installation and operation of these pipelines, Shanghai Luoying recommends that you use our main brand electric ball valve, which has a good expansion displacement compensation function, In addition, it can make up for the errors in the connection of the pipeline during the actual construction. After more than ten years of dedicated research, our company has finally established a perfect electric ball valve system. Technical standards: products shall be marked in the following order: product code, type code, structure code, performance code, working pressure, nominal diameter.
The product and structure codes are specified as follows: flexible electric ball valve RFJ, single ball valve D, double ball valve S, elbow W, concentric reducer Yt, eccentric reducer Yp, fan coil connector F. Mark example: RFJD-1.6 × 200,. It refers to a single spherical flexible electric ball valve with a nominal diameter of 200mm, and the working pressure is 1.6Mpa. Working pressure: the test pressure of the electric ball valve is 5 times of the working pressure, and the pressure is 3 times of the working pressure.
