Performance and use of expansion insulated discharge valve

BFL41W upspread thermal insulation discharge valve is easy to operate, open freely, flexible and reliable; The valve disc assembly and maintenance is simple, the sealing structure is reasonable, and the sealing ring replacement is convenient and practical. Structure: mainly composed of valve body, valve disc, sealing ring, stem, bracket, valve gland, handwheel, flange, nut, positioning screw and other parts. This type of valve in the pipeline should generally be installed horizontally.

The corrosion resistance of the upspread thermal insulation discharge valve

1, the use of media such as water, acetone, alcohol, ammonia, barium carbonate, benzene (WCB material temperature use -29ºC-425ºC).
2, the use of media such as particles, oil, pulp, carbon dioxide gas (stainless steel can be used temperature -60ºC-232ºC).
3, strictly prohibit the use of fluorine-containing ionic liquids (such as HF, etc.) can not use strong alkali and phosphoric acid (temperature less than 150ºC, concentration >30%). 4, the general working temperature of stainless steel ≤150ºC, pressure range 0, 6-2, 5MPA, more than this order to explain.

What matters should be paid attention to in the construction and installation of the upspread thermal insulation discharge valve

1, the installation position, height, import and export direction must meet the design requirements, the connection should be firm and tight.
2, all kinds of manual valves installed on the insulation pipeline, the handle shall not be downward.
3, the valve must be inspected before installation. For the valve whose working pressure is greater than 1.0MPa and plays a cutting role on the main pipe, the strength and tight performance test should be carried out before installation, and the qualified valve can be used. During the strength test, the test pressure is 1.5 times the nominal pressure, the duration is not less than 5min, and the valve shell and packing should be qualified without leakage. In the tightness test, the test pressure is 1.1 times the nominal pressure; No leakage on the sealing surface of the valve disc is qualified.
