Straight stroke series black water angle valve/ Angle type blackwater valve
（HD8P85H）

• Overview/Summary:

In the coal gasification process, the process characteristic medium of three-phase flow, high pressure, high temperature, and high flow rate causes severe erosion, cavitation, and corrosion of the valve body and internal components, resulting in short service life, frequent failures, and difficult maintenance of the black water regulating valve, which has become one of the pain points and difficulties that coal chemical users have been troubled by. The Hande straight stroke series black water angle valve adopts a new design concept and patented technology, which effectively avoids the above-mentioned problems in terms of structure, process and materials, combined with the characteristics of fluid mechanics.
This product was awarded the title of "China Good Instrument" by the Chinese Instrumentation Society in 2016, and was granted a national utility model patent on May 3, 2017 (patent number: ZL 2015 2 0203481.6）。


Coal gasification process, the process characteristics of the medium three-phase flow of high temperature and high pressure, high flow rate of the valve body and valve parts erosion, cavitation and corrosion is more serious, leading to Blackwater of valve fault, short cycle, maintenance difficulties, become one of the coal chemical industry has been plagued by difficulties of user pain points. The rotary cylinder type angle Blackwater valve using a new design concept and patented technology, thoroughly break the traditional straight trip of Blackwater angle valve palliatives, the occurrence of the above problems to avoid from the structure, process and material on the.
In 2016, the product was awarded the title of "good instrument in China" by China Instrument and meter Institute, and it was granted the national invention patent license on 2017, 05, 03 (patent number: ZL 2015 2 0203481.6).

• Characteristics:

(Sweep flow structure, no dead corners in the flow channel, no scaling, low flow resistance, self-cleaning function, no jamming or pulling, easy maintenance.)
Sweep flow structure, no dead angle, no scaling, flow resistance is small, with self-cleaning function, no stuck pull, easy maintenance.

1. Sweep flow structure, the valve body is designed with streamlined flow channels, no dead corners, smooth flow channels, and the valve body is not easy to scale;
Swept flow structure, the valve body is streamlined runner design, no dead angle, smooth flow
path, no scaling.

2. The valve stem can be treated with Ni60 surface and designed with a scraper, further enhancing the self-cleaning ability of the valve without any jamming or pulling of the packing;
Ni60 valve stem surface treatment plus scraper design, further enhance the valve's self-cleaning ability, no stuck and pull stuffing phenomenon;

3. The WC integral sintering of valve internals can be treated with TiCN coating, greatly improving the service life of the valve;
The WC integral sintered +TiCN coating for valve internals will greatly improve valve life.

4. Superior sealing performance, factory hard sealing can reach ANSI Class IV level;
Superior sealing performance, factory hard seal can reach ANSI, Class, Ⅳ level;

5. The structure is simple and compact, with a small installation position, making it easy to maintain and repair.
The utility model has the advantages of simple structure, compact structure, convenient maintenance and repair, small installation position and unlimited installation.
