Product description:Product description: the pressure reducing valve is pilot type, the main valve is single seat, and the hard alloy valvTe core is processed, The valve body is nodular cast iron (or cast steel), and the pilot va Tive is directly installed on the main valve through bolts On the valve, the valve can be closed without load.
Saturated steam:The flow rate is 5000kg/h, and the pressure is reduced from 8 bar to 5 bar.
From the fulcrum of the upstream pressure of 8 bar and the downstream pressure of 5 bar vertically downward, find the caliber that meets the flow conditions, and the valve of 80 mm is the smallest caliber that can meet the requirements.
Since the specific volume of superheated steam is high, the data found in the figure need to be corrected. The correction factor for overheating 55C (100. F) is 0.95, and overheating 110. C(200. F)
The correction factor of is 0.9. Therefore, for 80mm valve, if the steam is overheated at 55 ° C, the flow rate is 5900x0.95
=5600kg/h, which can still meet the requirement of 5000kg/h.
Install:The pressure reducing valve shal be installed on the horizontal pipeine and equipped with bypass and stop valve. The upstream
of the valve shall be equipped with drain valve and filter. The downstream pressure sensing pipe shall have a straight section at east 10 times the pipe diameter before and after.
FAQ:
(1)Q: How does a steam trap work?
A: The trap opens and closes automatically based on the pressure difference of the fluid. When the pressure in a pipe or equipment exceeds a preset limit, the trap opens, allowing water or condensate to drain from the system; when the pressure drops below the set value, the trap closes, preventing fluid from the system. drain.
(2)Q: What is the main purpose of a steam trap?
A: Traps are mainly used to remove condensation water from pipes or equipment to avoid damage to the system. They are usually widely used in steam systems, air compressors, cooling towers and other industrial equipment.
(3)Q: What are the common types of steam traps?
A: Common trap types include float traps, funnel traps, instantaneous traps and turbine traps, etc. Each type of trap has its own characteristics and scope of application.
(4)Q: How to choose a suitable trap?
A: When choosing a suitable trap, you need to consider factors such as the operating pressure, flow rate, media type and temperature of the system. In addition, the appropriate trap must be selected based on the size and installation requirements of the equipment.
