Forged steel ball valve damage how to solve it?

No matter what the valve, the sealing surface most likely to be destroyed, there will be inserted in the process of switching injury, bumps, crushing and other issues. Forged steel ball valve is easy under high pressure so that the two sealing surface atoms penetrate each other, resulting in adhesion phenomenon; if you move the two cover, you will appear adhesion tear, especially in the sealing surface of the higher the case of the more easily occur. If the wrought ball valve bumps or crushes during the closing process, the sealing surface may be partially worn or creased. Medium in the activities of the sealing surface prone to wear and tear, flushing, cavitation consequences, known as "media erosion." This situation often cause local damage, so the quality of the sealing surface must be processed, the erosion of the medium and chemical erosion of the alternating effect, which is the sealing surface will be strongly eroded. In addition to natural damage to the sealing surface, there are man-made damage, man-made damage due to: poor design, poor manufacturing, improper selection, improper installation, improper use and maintenance are not enough, and many other factors; So we must avoid these situations Occurrence, in order to make the ball valve in use without any problems, but also to ensure the life of the ball valve.

Seed Cleaning & Processing Machine

5XZS series seed cleaning & processing machine is the combined grain seed cleaning equipment. It installed wheat huller, air cleaning screen, vibration pre cleaning sieve, gravity table, vibration sieve cleaning and grading trunk. It maximizes one machine cleaning function, minimize the labor, easing of removability. This is our featured product. Since it comes to the market, it attracts customers' attention.

Combine grain cleaning machine function:

Removing coated wheat husk in the wheat huller.

Remove dust, light impurity by double air screen cleaners. Cyclone collects dust, stalk, and husk.

Remove big, small impurity in the pre cleaner.

Remove immature, eaten, sicken, moldy ones from healthy seeds on the gravity table.

Remove big, small impurity and grade seeds in the vibration sifter.

Seed cleaning & processing machine working flow:

Firstly wheat is fed from wheat huller hopper. After hulling, wheat is transferred by bucket elevator to precleaning sieving trunk for removing big and small impurity. There are two air screens at this sieving trunk two ends and connect air pipes. The dust cleaning system will remove the light impurity from grain twice before grain flow to gravity table. Then grain seed enter to the gravity table for removing the bad seeds. After Gravity Separator density separating, the seeds flow to main sieving trunk. In this main sieve trunk, the oversize impurity, undersize impurity will be removed. At same time, the sieve trunk can grade wheat to different size ranks.

Grain cleaning & Processing Machine has many adjusting handles. With these adjusting handles, operators can easily find the suitable air volume, vibration amplitude. Machine is user friendly and simple maintain.

We have 10 tons per hour and 20 tons per hour model. The wheat huller is optional. If clients do not clean wheat, they can order the model. The main sieve trunk we have two models: normal 4 sieve layer one and two sieving deck one. If customer only uses the machine for cleaning aim, no need to grade seeds by size, client can choose the two sieve decks type.
