Wear-resistant ball valve

Product introduction

Claisen wear-resisting valve series wear-resisting equipment company, is the company based on independent has a number of invention patents in China technology, specifically for the fluid contains various kinds of particles, powder and droplet application development, and proven by actual working condition of the product.The overall performance of the product, lead the world advanced level.

These wearable devices, claisen company of wear-resistant ball valve is composed of soft seal and hard seal ball valve.

Soft sealing ball valves of maximum temperature of 180 , suitable for use in transport slurry, and the pipe of pneumatic conveying of fly ash, for the use of switch.The wear-resisting ball valve used in:

1. Pneumatic discharge system of coal-fired power plants

2. The pneumatic transport warehouse pump manufacturer

3. The hydraulic discharge system in coal-fired power plants

4. Iron transport in the blast furnace gas mud pipes

5. Other similar purposes

Claisen company hard seal ball valve's highest use temperature increased.The highest temperature is 538 .Product is suitable for use under high temperature, the required valve has excellent wear resistance and erosion resistance of USES, can be used in:

1. The oil refining, petrochemical (slurry and catalyst)

2. The chemical

In the coal chemical industry (coal and coal seam gas lock, lock, lock the ash slag, emptying switch and adjust, balance, high temperature, slag, blackwater, ash water and oxygen, etc.)

Organic silicon (a cyclone blanking, cyclone, silicon powder feeding, emptying, slurry transportation, especially cans to dust exhaust exhaust control back to the bed, etc.)

Poly (cyclone blanking, filter material, silicon powder conveying, emptying, slurry transportation, fluidized bed heat economy cut off, reduction furnace exit quarantine, emptying switch and adjustment and high temperature hydrogen, etc.)

3. The oil and gas transportation

4. Mine

5. Metallurgy, non-ferrous metal and black metal)

6. Paper and paper pulp

7. Also suitable for use in other similar purposes, for throttling and switch.

Product features

This series of ball valve, by using polymer is made of soft seating materials and metal hard seal two major types of seating way.This series of ball valve not by increasing the hardness of ball valve internal parts in the material surface hardened, but the application of tribology and the principle of fluid mechanics, the improvement valve parts material in wear resistance and erosion resistance performance, reach the purpose of prolonging the service life of the valve.

The characteristics of this series of ball valve is

1. By applying the theory of boundary lubrication in modern tribology, reduces the abrasion between the ball and seat sealing deputy method, make the valve opened or closed in the process of the, of the composed of sphere and valve seat sealing surface seal between the grinding grain, and seal the surface with little or no direct contact, thus reduce the friction and wear between the sealing pair.

2. In practice, on the basis of fluid mechanics principle, make the valve opened or closed in the process of spherical surface by the fluid and the fluid in the midst of abrasive solid particles or powder erosion area, on the valve in the closed position, not to participate in the same seat sealing surface seals, and sphere surface on the valve in the closed position to participate in with the valve seat sealing surface sealing parts, will not suffer to the erosion of the fluid., so the valve can not only keep the existing excellent sealing performance, and prolong the service life of the item.

3. Change the ball valve in the fluid flow field, the existing technology makes the seat and the surface of the sphere to suffer less than, or suffered less erosion, prolong the service life of the valve.

Products with reliable sealing, wear resistance, erosion resistance, smooth operation, operating torque is small, and the advantages of long service life.
