Overview:
American standard H64H check the introduction of heat power station
Butterfly check valve for straight-through processing, the above several kinds of check valve in the connection form can be divided into the threaded connection, flange connections and welding of three. Also belong to the check valve class. Open-close part by medium flow and power to open or closed, to prevent the backflow medium valve check valve. Check valve belong to automatic valve class, mainly for the one-way flow of medium pipeline, only allowed to medium flows in one direction, in order to prevent accidents.
Model: H64Y - 1500 lb, H64Y - 1500 lb
Material: WCB, ZG20CrMoV ZG15CrMoV WC6, WC9, such as high temperature material
Connection: welding
Nominal diameter: DN50~DN300
Applicable medium: water, steam, oil, chemical industry, high temperature and medium pressure environments such as: 1500 lb, 2500 lb
Working temperature: - 29 ~ 570 centidegrade degree (note: the use of different temperature, the valve body material chooses different. Material selection of the valve body or use temperature to choose according to customer's request.)
Flow direction: one way
Type (channel) : straight through
Design criteria: API6D, BS1868 sealing form: hard seal processing custom: is America standard plant check valve product use:
Check valve is suitable for the American standard power station Class1500 ~ 2500 lb, working temperature - 29 ~ 570 centigrade degree under various working conditions such as petroleum, chemical industry, power plant piping. Applicable medium: water, oil, steam, etc.
Welding connection of check valve is suitable for the nominal pressure PN20.0 ~ 32.0 Mpa, the working temperature of 540 centigrade degree or less of oil, chemical industry, hydropower and thermal power plant under various working conditions such as the pipeline, cut off or connect medium. Applicable medium: water, oil, steam, etc.for example P57170v working temperature is 570 centigrade degree .
The high temperature power station check valve product structure features of American standard H64H:
1. The product design and manufacture according to standard E101 and JB/T3595-93 rules, reasonable structure, excellent performance, modelling.
2. The valve lumen self-tightening seal structure is adopted, and the medium pressure is higher, the sealing performance, the better.
3 for butt welding on both ends of the branch pipe, different to meet the demand of the takeover.
4. The disc and seat sealing surface using department too vertical (stellite) cobalt-based hard alloy surfacing and become, wear-resisting, high temperature resistance, good abrasion resistance, long service life.
5. High temperature compression part adopts high quality alloy steel manufacturing, safe and reliable, stable performance and long service life.
American standard H64H heat power station check valve installation should pay attention to the following things:
1, do not make the check valve in the line to bear weight, large check valve shall be independent support, make it not influenced by the pressure caused by the piping.
2, when installation, pay attention to the medium flow direction should be consistent with valve body by the ticket direction arrow.
3, vertical elevating disc check valve should be installed in vertical pipe runs.
4, elevating disc check valve should be installed in horizontal pipe runs.
