Long bracket structure with rolling friction bi-directional pressure hard seal butterfly valve CMDS944 / 364 / 344H / F / W product description: Long stent structure with rolling friction bi-directional pressure-hard sealing butterfly valve is a new generation of butterfly valve products, the activities of the valve seat and long stent plane bearing a new structure, the valve seat in the reverse pressure can automatically adjust the pressure seal åœ contact surface at the valve position , So that the entire seal are not under pressure to achieve full reverse pressure seal. The special geometric structure of the butterfly valve design makes the valve plate have the function of closing and closing the valve. When the valve is opened, the valve plate is completely separated from the valve seat as long as the valve shaft is slightly rotated to reduce the friction force and make the opening torque show the minimum and optimum condition , The seal is reliable, durable, widely used in urban heating, water conservancy projects, water, electricity circulating water, petroleum, chemical and other fields. Long stent structure with rolling friction bi-directional pressure hard seal butterfly valve Features: This product can be used in heating systems. Its main features are as follows 1, the product butterfly valve for heat pipe in the backwater pipe can replace the traditional ball valve. The butterfly valve has the advantages of compact structure, small volume, light weight and flexible operation, thereby reducing the cost instead of the ball valve, having significant economic benefits, and regulating the flow of the bidirectional pressure of the pipeline valve and intercepting the fluid. 2, special activities Seat structure can be adjusted seal åœ and seat position, adjust the pressure ratio, so that the sealing surface is not easy to damage, improve valve life. 3, The product bidirectional pressure multi-level hard seal butterfly valve than the ordinary one-way seal butterfly valve, to achieve a two-way sealing function, the reverse pressure can reach full pressure, the domestic valve companies failed to achieve the full pressure of the reverse pressure requirements. 4, the product of bidirectional pressure multi-level hard seal butterfly valve with two-way sealing function, flow resistance is small, with good hydraulic characteristics, the flow characteristics of a straight line inclined, energy-saving effect. The installation is not limited by the flow of the media nor is it affected by the location of the space and can be installed in any direction. 5, butterfly valve sealing performance, opening and closing times up to 5000 times, the service life of more than 5 years 6, the valve plate used in line with the balanced structure of hydrodynamic flow channel design, resistance coefficient at full open valve ≤ 0.15. 7, the maximum pressure of the product bidirectional butterfly valve reaches 300 ℃, can be applied to heat pipe conveying steam or overheating medium, bi-directional pressure in the return pipe to ensure zero reverse leakage requirements, will not affect the valve seal due to temperature changes performance.
