The use of valves is very common in the mining industry, which can control the flow of fluids, maintain the stability of the system, and ensure the safety of workers and equipment. Mining valve is a kind of equipment installed in the pipeline, widely used in mines, mines and mining processing equipment and other occasions. In coal mining, metal mining and other industries, it is often used in fluid conveying pipelines, regulation and control systems. Due to the harsh production environment of the mining industry, it is necessary to have the characteristics of wear resistance, corrosion resistance, high temperature resistance, good sealing and durability to ensure the normal operation of the equipment and safe production.

For users, choosing the right valve is one of the key factors to ensure the normal operation of equipment and production safety. Their design, manufacture and application are directly related to the production efficiency, quality and safety of mines. In addition to quality and safety requirements, it is also necessary to meet certain energy conservation and environmental protection requirements. Aisenberg Valves is committed to continuous research, design, manufacturing and development in order to better use in mining and coal mining scenarios. Aisenberg high pressure flat gate valve on the one hand designed the diversion hole, with advanced drag reduction structure and streamlined design, to reduce energy consumption and improve efficiency; On the other hand, the spray tungsten carbide hardening process and two-way sealing structure are used to reduce the leakage of liquids and gases, so as to protect the environment and health.

Aisenberg Mine valves - High pressure flat gate valves

It can withstand high pressure and high temperature environment, with anti-corrosion, anti-wear, explosion-proof and durable characteristics

Aisenberg high pressure flat gate valves continue to innovate and optimize the structure:

The selection of high-pressure flat gate valve with upper diversion hole is adopted, and the diversion hole is designed on the upper part of the valve plate. When the valve stem moves upward, the valve is closed, and when the valve stem moves downward, the valve is opened, so that the valve plate is always in contact on the sealing surface of the valve body, preventing the medium from washing the sealing surface and bringing part of the residual medium into the upper chamber through the upper diversion hole. When the valve is opened the next time, it will be brought into the channel by the valve plate to prevent accumulation of blockage. At the same time, in order to cope with the possible erosion and erosion, the valve plate and the valve body sealing surface, the spray tungsten carbide hardening process is used.

Aisenberg High pressure Flat gate Valve Advantages:

√ The valve seat is sealed by O-ring and the floating valve seat structure with preload force, so that the valve inlet and outlet are sealed bidirectional; And the opening and closing torque of the structure is only 1/2 of the ordinary valve, which can easily open and close the valve.

√ The gate of the valve with the upper diversion hole, whether fully opened or fully closed, is always consistent with the sealing surface, and the sealing surface is not directly washed by the medium, thereby extending the service life.

√ The valve adopts the packing structure with self-sealing ability, no need to adjust frequently, the opening and closing are very light, and the sealing is reliable, the stuffing box is equipped with an auxiliary sealing grease injection structure, the sealing performance is absolutely reliable, truly achieve zero leakage; It solves the problem that the packing of general valve is most likely to leak out.

√ When the valve is closed, the high pressure in the inner chamber can be automatically removed (see the working principle diagram for details) to ensure safe use.

Aisenberg High pressure flat gate valve working principle:

→ When the internal pressure of the valve is equal (1), the gate is closed, and the PTFE sealing ring on the surface of the seat forms an initial seal, which cleans both sides of the gate each time the valve is opened or closed. (Figure 1);
→ When pipe pressure is applied to the valve (2), the pressure acts on the gate, forcing it close to the PTFE ring on the outlet seat, compressing it until the gate stops on the steel seat, so that a double seal is formed, first a PTFE to metal seal, then a metal to metal seal, and the seat is also firmly pushed into the groove, at this point (3), ○ Ring prevents any rear media flow. (Figure 2)
→ After pressure relief of the valve chamber, an inlet seal is formed, and the pipe pressure acts on the inlet seat (4), causing it to move towards the gate, then a PTFE seal is formed on the metal, at the same time, the 0 ring (5) forms a tight seal with the seat groove. (Figure 3)
→ The valve automatically releases excess pressure. When the valve chamber pressure is greater than the pipe pressure, due to thermal expansion, the excess pressure pushed by the inlet seat into the groove valve chamber is discharged into the pipe between the seat and the gate. (Figure 4)

We're still working on it

The development of Aisenberg mining valve technology does not stop, including the use of new materials and the updating of industry standards, safety and leakage prevention is the main driving force. End users benefit from safer and longer life cycles at a lower cost.
