Coal chemical special slag lock hopper valve

Coal chemical special slag lock hopper valve

1、 Product Overview：

In the rapidly developing coal chemical industry projects,Lock slag lock bucket valveThe device is one of the important equipment for measuring process medium fluids. The correct selection enables precise and stable measurement of production equipment, as well as energy conservation, consumption reduction, safety, and environmental protection. The slag lock bucket valve has the characteristics of low fluid resistance, smooth flow, fast opening and closing, and easy automation control, and has therefore been increasingly widely used. Widely used in industries such as coal chemical, polycrystalline silicon, petroleum, chemical, power, metallurgy, cement, sugar, mining, etc., it has received high praise from users worldwide and full recognition from the industry.

2、 Product process:

Process standard: Adopting a unique ball grinding process, the ball and grinding tool rotate in different directions in space to achieve extremely high roundness and smoothness on the surface of the ball, and the sealing performance of the valve fully meets or exceeds international standard requirements.

Complete fire-resistant structural design

Process structure: The sealing surface of the valve adopts a metal to metal sealing structure, the packing adopts flexible graphite, and the gasket adopts stainless steel or titanium alloy+flexible graphite structure. Therefore, valves can ensure reliable sealing even in the event of a fire.

Natural anti-static structure design

IIIApplication field：

Lock slag lock bucket valve is suitable for various pipelines, used to cut off or connect fluid media in pipelines. Different materials are selected and can be applied to non corrosive media, weakly corrosive media, nitric acid, acetic acid, oxidizing media, urea and other industries. It is particularly suitable for harsh working conditions such as solid particle media, such as slurry, coal powder, ash and slag. The driving mode of the slag lock bucket valve is divided into manual, turbine worm drive, pneumatic or electric. Lock slag lock bucket valves generally use flange connections, but can also use butt welding connections, threaded connections, clamp connections, or customized special process connections according to user requirements.

4、 Technical characteristics：

In addition to structural features such as preventing misoperation, preventing valve stem from flying out, and setting up a driving device installation platform, the slag lock bucket valve also has the following technical characteristics. The ball and valve seat of the slag lock bucket valve are completely sealed with metal to metal. In order to ensure reliable sealing of the valve under various temperatures and pressures, various advanced hardening technologies for the ball and valve seat can be used according to the different usage conditions and requirements of users, including supersonic spraying, nickel based alloy spraying welding, surface special hardening, hard alloy spraying welding, and the use of high-strength and high hardness ceramic materials. The surface hardness of the ball and valve seat can generally reach HRC75 or above, and the highest can reach HRC90 or above. The inlet and outlet are made of diamond wear-resistant alloy. The sealing surface material not only has properties such as temperature resistance, friction resistance, and impact resistance. The slag lock bucket valve can be applied to the vast majority of harsh working conditions. Especially used in industries such as coal chemical, polycrystalline silicon, petroleum, building materials, metallurgy, power, mining, etc.

Prevent valves from getting stuck at high temperatures

5、 Product advantages：

The sealing surface of the valve adopts a metal to metal sealing structure, the packing adopts flexible graphite, and the gasket adopts stainless steel or titanium alloy+flexible graphite structure. Therefore, valves can ensure reliable sealing even in the event of a fire.

Natural anti-static structure design

The metal parts such as the valve body, valve seat, and ball of the slag lock bucket valve are in close contact, naturally forming an electrostatic channel. Therefore, the slag lock bucket valve does not require a specialized anti-static device.

Dual blocking and releasing function

The slag lock bucket valve generally adopts a ball valve front seat sealing structure. The two valve seats of the slag lock bucket valve can independently cut off the medium at the inlet and outlet ends, achieving dual blocking function. When the ball valve is closed, even if both the inlet and outlet of the valve are under pressure at the same time, the channels in the valve and at both ends can be blocked from each other, and the remaining medium in the middle chamber can be discharged through the relief valve. The slag lock bucket valve adopts a ball back seat sealing structure. Generally, one-way sealing is used and the flow direction is marked on the valve body. If the user has special process technology requirements, a proprietary technology structure with bidirectional sealing can be used to lock the slag and bucket valve.

Anti clogging technology solution

A precise reverse blowing device is designed on the upper half of the feed inlet of the slag lock hopper valve for online reverse blowing of ash, slag, and slurry. A proprietary technology double-sided soft scraper is designed and configured at the lower end of the slag lock hopper valve inlet, which can smoothly remove ash, slag, and slurry. A relief valve is installed at the bottom of the slag lock hopper valve, and the valve chamber is cleaned regularly to ensure zero leakage, no scaling, no adhesion, no coking, and no condensation inside the valve chamber, so as to maintain high-performance online operation and measurement of the slag lock hopper valve at all times.

压力等级： Class50-Class3000PN1.6-PN160 JIS3K-JIS20K

Medium temperature: -66 ℃~995 ℃

Technical scope: NPS2-NPS24

6、 Structural Function：

Under high temperature conditions, thermal expansion can easily cause the ball and valve seat to jam, resulting in the valve being unable to open. The slag lock bucket valve adopts a proprietary sealing technology structure of disc springs or springs. The thermal expansion of components at high temperatures can be absorbed by the disc springs or springs, so it can ensure that the valve remains within the set constant temperature range at high temperatures without being stuck, and can be flexibly opened and closed continuously at high temperatures.
