Specifications

Thermal insulation material

Insulation discharge valve is mainly used for reactors, tanks and other containers in the bottom of the discharge, discharge, sampling, and no dead zone off operation, phosphorus and phosphorus light medium, hydrofluorocarbons, hydrochloric acid, sodium hydroxide and potassium hydroxide, suitable for all kinds of acid, alkali, salt solution and organic solvent. Easy to operate, open free, flexible and reliable movement; valve flap valve assembly and maintenance is simple, the structure is reasonable, sealing ring replacement convenient and practical. The structure is mainly composed of a valve body, valve, seal, valve stem, valve gland, bracket, handwheel, flanges, nuts, screws and other parts. Its main parameters are: nominal diameter DN, discharge valve rated flow coefficient KV, discharge valve nominal pressure and differential pressure, discharge valve body and valve components material, discharge valve flow characteristics, discharge valve for temperature, discharge valve power supply voltage and control signal, discharge valve is attached, etc..

General caliber

Is a variety of pipe and pipe fittings of general caliber, the same nominal diameter pipe and pipe fittings can be mutually connected, with interchangeable. It is not the actual meaning of the pipe diameter, although its value with the pipe diameter is close or equal, in order to make the pipe, pipe fittings connection size uniform, using nominal diameter (also called nominal diameter, nominal diameter). For example, welded steel pipe according to thickness can be divided into thin wall steel tube, ordinary steel pipe and thick steel pipe. Its nominal diameter is not outside diameter, nor is the inner diameter, but the approximate diameter of ordinary steel pipe a nominal size. Each nominal diameter, corresponding to an outer diameter, the diameter of which is different with different thickness. Metric mm nominal diameter can be said, can also be British in said. With nominal diameter pipeline accessories, meaning with tube.

nominal pressure

The maximum working pressure allowable at a certain temperature when applied to a certain temperature, PN. For carbon steel valve, the maximum working pressure allowable when 200 is applied, the maximum working pressure allowable under 120 for the cast iron valve body, the maximum working pressure allowable under 250 for the use of stainless steel valve. When working temperature increases, the pressure of the valve will be reduced. For example, nominal pressure for 6.4MPa (PN64) carbon steel control valve for 300 at the time of 5.2MPa, with 400 for the 4.1MPa, for 450 at the pressure of 2.9MPa.

main application

Discharge valve is mainly used in the reaction kettle, storage tanks and other containers of the bottom discharge, discharge, sampling and no dead zone off operation. With the aid of the valve at the bottom of the flange welded to the tank and other containers at the bottom, thus eliminating the process of media usually in the case of the container export. The inner cavity of the valve body sealing ring is erosion resistant, corrosion resistant, open the valve at the moment, you can protect the body from being medium erosion, corrosion, and seals for special treatment, the surface hardness of HRC56-62, with high wear and corrosion, the valve cover seals are required when welding hard alloy seal associate with thread sealing, to ensure the reliability of sealing and prevent scarring. At the same time to take a short trip valve design.

Main equipment type and performance

1, discharge valve, corrosion resistance: 1 the use of media such as water, acetone, alcohol, ammonia, barium carbonate, benzene (WCB) temperature using -29 -425. 2 prohibited the use of fluoride ionic liquids (such as HF) also cannot use alkali and phosphate (temperature less than 150 DEG C, the concentration of >30%). The general working temperature less than 3 stainless steel and 150 DEG C, the pressure range of 0.6-2.5MPA, more than the prescribed order to explain.

2, discharge valve, corrosion resistance: 1 PTFE and metal bonding, tensile properties of general, acid, concentrated acid, etc.. 2 the use of medium such as particles, oil, paper pulp, carbon dioxide gas (stainless steel material can be used in the temperature of -60 -232. 3 prohibited the use of fluoride ionic liquids (such as HF) also cannot use alkali and phosphate (temperature less than 150 DEG C, the concentration of >30%). 4 the general working temperature of the stainless steel is -5, -225, and the pressure range is 0.6-1.6MPA.

3, discharge valve: glass lined equipment is high silicon content of glass glaze. By 900 degrees Celsius temperature coated with metal. It has good mechanical properties and corrosion resistance, can prevent the media and metal ions to replace the role of the impact of pollution products, and the surface is bright and clean, wear, there is a certain thermal stability. This valve phosphorus and phosphorus light medium, hydrofluorocarbons, hydrochloric acid, sodium hydroxide, potassium hydroxide outside the competence of various acid, alkali and salt solution and organic solvents. A, corrosion resistance: 1. General inorganic acid, organic acid, alkali liquid (P less than or equal to 60 DEG PH = 12) and organic medium. 2 in hydrochloric acid, nitric acid, and other strong corrosive medium is better than stainless steel. Prohibited the use of fluoride ionic liquids (such as HF) also cannot use alkali and phosphate (temperature less than 150 DEG C, the concentration of >30%). B, heat resistance, allowing the use of at -30 DEG -240 DEG between (high temperature blast is less than 120 degrees C). C, has a smooth surface. Difficult to bond materials, easy to clean. E, insulation: impact resistance is smaller to 2500 g / cm, and thus the use of hard material impact should be avoided. F, pressure 0.6MPA
