Detailed parameters of H42H-16C cast steel vertical check valve DN700.

Hello, it is a pleasure to serve you, and to make the following answers for you: detailed parameters of H42H-16C cast steel vertical check valve DN700: 1. Model:

H42H-16C2, Material: Cast Steel 3, Applicable Medium: Liquid, Gas 4, Applicable Temperature:

20 200 5, applicable pressure: connection method: flange connection 7, applicable pipe diameter:

The reasons for the problem of DN700: 1. The valve material does not meet the requirements: the valve material does not meet the requirements, which may cause the valve to be damaged, thereby affecting the normal use of the valve.

2. Valve connection is not firm: If the valve connection is not firm, it may cause valve leakage, which will affect the normal use of the valve. 3. The valve parameters do not meet the requirements

If the valve parameters do not meet the requirements, the valve may be damaged, which will affect the normal use of the valve. Solution: 1. Check the valve material

Check whether the valve material meets the requirements, if it does not meet the requirements, it should be replaced with a new valve material in time. 2. Check the valve connection: check whether the valve connection is firm, if not, the valve should be reconnected in time.

3. Check the number of valve parameters: check whether the valve parameters meet the requirements, and if they do not meet the requirements, they should be replaced with new valve parameters in time. Steps:

1. Check the valve material: check whether the valve material meets the requirements, if it does not meet the requirements, it should be replaced with a new valve material in time. 2. Check the valve connection age

Check whether the valve connection is firm, if not, the valve should be reconnected in time. 3. Check the valve parameters: check.

Summary. Pro, check valve model H61Y-600, 1B is made of carbon steel.

Check valve model H61Y-600, what is the material of 1B.

Pro, check valve model H61Y-600, 1B is made of carbon steel.

Carbon steel is a silver alloy with iron-carbon coded silver containing and covering carbon. It is also called Chiyan carbon steel. Generally, it also contains small amounts of silicon, manganese, sulfur and phosphorus. Generally, the higher the carbon content in carbon steel, the greater the hardness and the higher the strength, but the lower the plasticity.

Heat treatment is an important metalworking base cultivation process in the state of Prime, with the aim of improving the properties of steel (in-service and process properties). The process characteristics of heat treatment of steel are that the steel is heated to a certain calming temperature, kept warm for a certain time, and then cooled at a certain cooling rate. The properties of the steel are changed through this process.

Quenching heat treatment is to heat the carbon steel to 30-50 °C above AC3 or AC1, and put it in different cooling media for rapid cooling (the cooling rate is greater than the cooling speed of Linli Dajie) to obtain the martensitic structure (m). The quenched structure is martensite and residual austenite.

Check valve H76W-150LB-P+DN150 spring compression.

Hello, according to your question, the "stop valve H76W-150LB-P+DN150 spring compression" will be answered by me, and the check valve H76W-150LB-P+DN150 spring compression is 44. Check valve refers to a kind of valve that has a circular disc opening and closing parts and relies on its own weight and medium pressure to block the backflow of medium. It is an automatic valve, also known as check valve, check valve, return valve or isolation valve.

The disc movement mode is divided into lifting type and swing type. The lifting check valve is similar in structure to the globe valve, only the stem that drives the disc is missing. The medium flows in from the inlet (bottom) and out from the outlet (top).

The valve is opened when the inlet pressure is greater than the sum of the disc weight and its flow resistance. Conversely, the valve is closed when the medium flows backwards. Swing-start check valves have a tilted disc that rotates around the shaft and work similarly to a lift-lift check valve.

Check valves are often used as foot valves for pumping devices to stop the backflow of water. The check valve is used in combination with the globe valve to play the role of safety isolation. The disadvantage is that the resistance is high and the sealing is poor when closed.
