Product Description

Product description:

  KAQ347F gas ball valve is a valve utilised to cut off, distribute and adjust the movement route of the medium in the pipeline. It only demands to rotate 90 levels and a small turning torque to shut tightly. It is most suitable as a switch or a shut-off valve. The ball valve has the positive aspects of compact structure, trustworthy sealing, easy construction, practical servicing, not simple to be eroded by the medium (since the sealing area and the spherical surface area are frequently in a closed condition), and simple operation and maintenance. The applicable medium of this merchandise is organic fuel, etc. It is mostly utilized to minimize off or join the pipeline.

Objective and Functionality Requirements
 ball valve is suitable for all kinds of force, temperature and medium of medium and modest diameter pipelines. It controls the opening and closing device of connecting or slicing off the pipeline medium, and presses the ball on the valve seat of the outlet end by the medium strain. The strain and diameter utilized are minimal.

Procedure Theory and Structure Description

1. The ball valve channel is sleek, which is practical for cleaning pipeline and conveying medium.
2. The gasket is manufactured of PTFE ( ), it has excellent lubricity and elasticity. Aside from, it has a small friction with the sphere, which make it has a long provider existence.
3. Rotating the 90° to open up and the close the valve, which is convenient and rapid.
4. The fluid resistance of the ball valve is small. When it open up completely, the cross-sectional spot of the ball channel, valve body channel and connecting pipe are equivalent and hook up in a straight line. The medium flowing by way of the ball valve is equivalent to flowing via a straight pipe. The fluid resistance of the ball valve is the smallest among CZPT valves.
5. The driving modes consist of handbook, CZPT travel, pneumatic and electrical (explosion-proof), which can understand remote automated handle, which can satisfy the user’s demands for CZPT operating situations.

Attributes of Solution Construction

1. Straightforward to work: The ball is supported by the upper and decrease bearings, lowering friction and removing the extreme torque caused by the enormous sealing load formed by the inlet force pushing the ball and the sealing seat. Even below the maximum functioning stress can accomplish smaller sized torque.
2. Good sealing performance: a spring is provided at the tail conclude of the steel valve seat to ensure adequate pretension. When the sealing surface wears out throughout use, the valve carries on to ensure excellent sealing performance underneath the action of the spring.
3. Drainage pipeline: Sewage holes can be set at the best and the bottom of the valve body, which can exam if the valve is leakage or not.

Installation&Maintenance

1. The ball valve has been examined for CZPT performances these kinds of as toughness, sealing, and switching according to the “valve inspection and take a look at” normal ahead of leaving the manufacturing unit, so as to meet up with the demands of the regular, and take away the oil and particles inside of and exterior the valve cavity. The two finishes are sealed with caps.
2. Ahead of set up, the user must check carefully regardless of whether the articles of the nameplate is in accordance with the problems of use. It is not allow to put in and use the valve with above-stress or over-temperature.
3. Before set up, KMO suggests that the caps at the two finishes of the inlet and outlet ought to be removed, and check meticulously regardless of whether there is dust adhering in the valve cavity. At the identical time, checking whether or not the bolts, nuts and packing glands of the connection elements of the valve are loose. If they are unfastened, they ought to be tightened.
4. Connecting the ball valve to the pipeline should be according to the made connection approach. After fixing, the valve ought to not face up to big tensile, compression, bending and twisting stresses to keep away from damage to the valve.
5. The transmission manner of the ball valve consists of manual, CZPT transmission, pneumatic, electric powered, hydraulic and other driving strategies. Wrench (or take care of) is utilized for handbook operation. CZPT , electric, hydraulic, and so on. are set up corresponding drive units over the ball valve. Please refer to the generate gadget guide for certain matters.
6. The wrench (take care of) can be turned 90° to open and shut the ball valve. Switch the valve stem clockwise to near the valve and change counterclockwise to open up the valve.
7. The ball valve must be stored in a dry and ventilated location, and out of doors storage is not allowed. Channels at both finishes are blocked with heads to stop debris from getting into.
8. In the course of storage, the ball valve ought to be completely open up to defend the ball sealing surface and the valve seat sealing surface.
9. If the ball valve is in a status of CZPT -phrase storage,  it need to be often checked to remove the grime in the interior cavity and grease the processing surface area.
10. If the ball valve is installed in the pipeline, it need to be checked routinely to make certain every thing is normal. If there is any difficulty, you need to have to repair it instantly. 
11. When the ball valve employed is disassembled and reassembled, KMO reminds that it need to be inspected and tested in rigorous accordance with the appropriate countrywide expectations and issued with a certificate before it can be used once again.
12. When there is medium force in the ball valve, it is not allow to exchange or add packing, and it is strictly forbidden to disassemble any components on the valve and loosen any powerful components, otherwise it might cause an incident.
13. The storage, use, maintenance and troubleshooting of valves shall be recorded in element.
14. It is not allow to weld, maintain or substitute elements beneath the point out of valve below stress.

15.  

Worm gears are correct angle drives that give huge gear ratios with reasonably quick center-to-heart distances from 1/4″ to 11″. When appropriately mounted and lubricated, they provide as the quietest, smoothest-running gear variety. Simply because worm equipment drives can attain large equipment ratios, greatest reduction can be achieved in a smaller sized room than several other sorts of equipment drives. The worm and worm gear operate at a 90° angle on non-intersecting axes.
