Product Overview


Brief
Ceramic double gate valve, also known as ceramic parallel double gate valve or dry ash valve, is a kind of ceramic gate valve. Therefore, its structure and working principle are consistent with the ceramic gate valve, and its opening and closing body (valve plate) is driven by the valve stem to the sealing surface of the valve seat for lifting movement, which can be connected or cut off the fluid channel.
Ceramic double gate valve is mainly used for dry powder material inlet, discharging and conveying pipeline, as a cut-off and connecting medium channel, as a warehouse pump discharge valve, balance valve, exhaust valve, blockage valve, can also be used as a pipeline switching valve and ash warehouse discharge valve, with good sealing performance, small starting load, less ash and ash accumulation phenomenon, wear resistance, long service life characteristics.




Product features:
1. The design concept of the valve has the incomparable characteristics of ordinary valves. As a fluid control system, the valve sealing surface damage and leakage caused by debris can be effectively solved for a long time.

2. The valve adopts a spring self-sealing structure and a special sealing surface, so that the sealing pair is always consistent at any position, can completely scrape the residual dirt (such as sediment, welding slag and other attachments), the sealing surface is not damaged, because the sealing surface is surfacing with high hardness corrosion resistant alloy material, After being used by many manufacturers, it is proved that the structure can not only scrape all kinds of dirt on the sealing surface, but also cut off the stainless steel welding rod of Phi 5mm, and the sealing surface is not damaged at all, and it works normally.

3. Because the self-sealing structure of the spring in the valve can automatically compensate for the normal wear of the sealing surface, on the one hand, due to the strong leakage rate of the seal, on the other hand, the working life of the valve is greatly improved, and the cost is saved for the enterprise.

4. The valve adopts a wedge roller type switch mechanism, which can switch the valve easily and make up the early warning device of a small amount of leakage on the sealing surface. If there is a small leak in the valve, as long as the handwheel is closed, the valve can be kept without leakage, and ordinary valves do not have this skill.

5. Due to the use of special switching mechanism, to prevent the ordinary gate due to large temperature changes, the gate plate stuck, and can not open the phenomenon.

6. The valve has an automatic blow-down system at the bottom to keep the body cavity clean and residue free at all times.

Seven. A dust-proof mechanism is provided in the valve body to ensure that there will be no dirt immersed in the valve cavity, and the internal mechanism will fail

Principle of action:
The working principle of ceramic parallel double gate valve: with the external power provided by the cylinder or hand wheel, the valve stem drives the valve plate to move up and down to realize the valve opening and closing. During the valve opening and closing process, the valve plate and the seat are closely connected to achieve sealing. Among them, the working principle of the pneumatic ceramic double gate valve is: when the air source enters from the upper air port, the valve stem drives the valve plate to move downward, and the valve is closed. When the air source enters through the lower air inlet, the valve stem drives the valve plate to move upward and the valve opens. The spring is loaded between the valve plate and the seat, and the spring spring always makes the valve plate pressure to the seat to ensure the sealing of the valve, and allows the valve plate to move in the vertical up and down direction, which helps to compensate the thermal expansion of the valve parts, and can overcome the impact of any change in back pressure on the seal and prevent the particle medium from entering between the two sealing surfaces. In the process of opening and closing, the valve plate can produce rotation, causing grinding and polishing between the sealing surface, and because the valve body is eccentric to the channel, eddy currents will be generated when the material is opened and discharged, and the formed material vortex will clean the valve cavity by itself. All these characteristics make this valve have a very long service life.
