1. Top loading design:

After the line system depressurized. Can be checked and repaired online, so that maintenance is simple.

 

2. Packing loading design:

Double sets of low leakage packing and loading disc spring design to avoid valve leakage due to frequent opening.

 

3. K-type plate structure:

The unique K-type plate structure has less opening force than the conventional wedge type double plate gate valve, and will not die at high temperature due to the different material expansion ratio, so the reliability of the high temperature pipeline is higher than the traditional parallel double gate valve.

 

4. Valve seat and valve body integrated structure:

According to the requirements of coal chemical industry, the valve seat is made into an integrated structure with the valve body to avoid the phenomenon that impurities enter the valve seat clearance and cause the valve to jam.

 

5. Full path design:

Full diameter diversion hole design, easy to clean online, smooth flow channel when fully opened, flow resistance coefficient is small, no pressure loss.

 

6. Diversion hole structure design:

The guide hole structure can ensure that when the valve is fully opened or fully opened, the gate and the sealing surface of the seat are always in contact to ensure that the sealing surface will not be washed by the medium, thus extending the service life.

 

7. Automatic pressure relief:

The valve has an automatic pressure relief device to ensure the safe operation of the line and equipment.

 

8. Bidirectional forced seal design:

The sealing surface of the valve plate and the seat is surfacing with cemented carbide, which can achieve a complete two-way forced seal and ensure the reliability of the seal.

Q: Why choose the K-shaped plate flat gate valve without diversion hole?

A: This valve has a double seal, two-way seal and strengthen the role of mechanical seal, and has the function of full diameter can be cleaned, can be widely used in geothermal steam, oil, natural gas production and transportation, collection pipelines and storage devices, can also be used for gas, acid, alkali and other corrosive media.

 

Q: What is the applicable condition:?

A: 1. Hydrogenation unit

2. Coal chemical industry

3. Harsh working conditions

 

Q: Can it be used in high temperature condition?

A: Yes, the valve in high temperature condition anti-rise dead, top mounting design, can achieve online maintenance..

 

Q: Describe your company's design/development process?

A: Contract review -- Design/development task List -- Design/development input -- design/development output -- design/development review -- design/development verification -- design/development confirmation.

 

Q: What is the role of design/development review? When does the design/development review take place?

A: The design and development review is conducted at the appropriate stage of the design and development, generally before the end of the design and development phase, to evaluate the ability of the design and development results to meet the requirements, and to propose existing problems and suggestions for improvement.

 

Q: What are the usual approaches to design/development validation?

A: Theoretical calculation, experimental verification, application verification of new materials and new technologies.

 

Q: What are the methods of design/development validation? What is the difference between design/development validation and design/development validation?

A: The methods are: 1 the finished product is tested under simulation conditions, 2 provide samples for customers to try; Design/development verification means that the Technical department is responsible for the whole process of design and development, according to its internal division of all the design work items should be designed to meet the design input requirements; Design/Development validation means that the Technical Department is responsible for the final result of the design to ensure that the product will meet the specified requirements for use or known intended use.

 

Q: Low temperature valves often lengthen the length of the valve stem, in addition to the need to calculate the strength of the valve stem when designing what is fulfilled?

A: Check the stability of the valve stem.

 

Q: What are the conditions for calculating the strength of the shell?

A: The strength calculation of the shell should generally have the nominal pressure, the maximum inner diameter of the cavity, and the allowable stress value of the material.
