Product Description

  The FG45Y pipe discharge valve is improved from the upspread discharge valve, but the sealing structure of the valve has been changed. The improvement of this valve is enough to change the shape and structural principle of the valve. Mainly used for the bottom of the reactor to play the role of discharge. Its working principle is similar to the globe valve, but the sealing requirements are higher than the globe valve. Structure characteristics: pipe discharge valve is mainly composed of valve body, bearing, valve column, valve stem, packing gland, handwheel and other parts. The valve body is made of WCB or stainless steel casting, the inlet and outlet of the valve body is 45 degrees Angle, and the body is Y-shaped. Valve body inlet flange connection, the valve outlet flange size is the same, the inlet flange protruding inside the round tube shape in the valve body as one, the edge of the tube mouth welding STL (hardness and good) and the tourbill-shaped valve disc bevel seal. Valve disc Tuo structure is advantageous to open the valve. Inclined sealing is to make the sealing surface into a cone, so that the contact surface is narrow, this kind of sealing under a certain sealing force, the sealing ratio is greatly increased, it is easier to achieve sealing, compared with the plane sealing structure, the applied sealing force is smaller. Because the sealing surface is narrow, it is not easy to make the valve disc correctly pressure to the seat surface when closed, in order to improve the sealing performance, the valve disc must be guided.
When the valve disc is guided in the valve body, the valve disc is subjected to the lateral push force of the fluid by the valve body, rather than by the valve stem, which further enhances the sealing performance and the reliability of the packing seal. The T-shaped tail of the valve stem is fixed with a cap and the valve disc, and the middle is matched with the packing (polytetrafluoroethylene) in the valve body to play a sealing role.
Installation and maintenance
of the valve should be neatly stored in the general air drying warehouse, it is strictly prohibited to pile or open storage, both ends of the valve diameter must be blocked with blind plates.
1. Before installation, carefully check whether the mark and certificate on the valve meet the requirements of use, and clean the valve to remove the damage caused in the process of transportation and storage.
2. The valve can be installed in any working position, but attention must be paid to maintenance and easy operation.
3. When installing, the standard torque plate hand should be used to symmetrically tighten the stud connecting the flange, and should avoid distortion or too tight.
4. It should be kept clean often during use, and the valve stem thread and the part with thrust bearing must be lubricated regularly. The maintenance and maintenance of the electric device should be carried out according to the requirements of the "Valve electric device manual".

Structure characteristics
series of discharge valve Y type and Angle type two structural forms, according to the needs of actual working conditions, the form of discharge port design with pipe connection and flat bottom two, the body cavity is equipped with erosion resistance, perfect protection plate, in the opening of the valve moment, can protect the valve body from being washed by the medium, corrosion, and the whole of its special surface treatment, Make the surface hardness reach HRC60~65, with high ***, *** excellent function.
