Characteristic Analysis of Q47 Fixed Ball Valve

Q47-type fixed ball valve is a new generation of high-performance ball valve for long-distance pipelines and general industrial pipelines, its strength, safety, resistance to harsh environments in the design of special consideration for a variety of corrosive and non-corrosive Sexual media. It is compared with the floating ball valve, work, the valve fluid pressure in front of the ball on the force generated are all transmitted to the bearing, the ball will not move to the seat, so the seat will not withstand excessive pressure, so the fixed ball valve Small torque, small deformation of the valve seat, stable sealing performance, long service life, suitable for high pressure, large diameter occasions. Advanced spring pre-seat assembly with self-tightening features for upstream sealing. Each valve has two seats, each direction can be sealed, so there is no flow restrictions installation is two-way. The valve has two types and three types of two valve body structure, flange connection with bolts, sealed with PTFE reinforced inlaid stainless steel ring, the back of the ring without spring to ensure that the valve seat close to the ball, keep seal. No upper and lower stem PTFE bearings to reduce friction, the operation of labor-saving, no adjustment at the bottom of the small shaft to ensure that the ball and seal the junction location. Full diameter: valve flow aperture and pipeline diameter, in order to clean the pipeline. (1) Operational Effort: The ball is supported by the upper and lower bearings to reduce the friction and eliminate the excessive torque caused by the huge sealing load caused by the inlet pressure pushing the ball body and the sealing seat. (2) Reliable sealing performance: The PTFE single-material sealing ring is embedded in the stainless steel valve seat. The end of the metal valve seat is provided with a spring to ensure that the sealing ring has sufficient pre-tightening force. When the sealing surface of the valve is worn during use, The lower valve continues to ensure good sealing performance. (3) fire structure: To prevent the emergence of sudden heat or fire, the PTFE seal burned, a larger leak, and to promote the fire, the ball and seat set up a fire seal ring, the seal burned , Under the spring force, the valve seat ring quickly push the ball, the formation of metal and metal seals, play a certain degree of sealing effect. Fire test in line with APl 6FA and APl 607 standards. (4) automatic pressure relief function: When the valve medium chamber stagnant abnormal increase in pressure exceeds the spring preload, the seat back from the ball, to achieve the effect of automatic relief pressure relief valve seat automatically reset. (5) Discharge pipe: the body is set up excretory larvae L, can check the valve seat for leaks, at work, the valve is fully open or fully closed, the removal of the cavity pressure can be directly replaced filler; can be discharged Cavity retentions, reducing the media on the valve pollution. (6) This valve is designed with an auxiliary valve seat emergency seal system. Once the seal is damaged or there is an emergency situation that can not be sealed, the auxiliary seal system can be used to seal the seal face Injection of the corresponding sealant to repair the sealing surface, to achieve an emergency seal. When the medium to be conveyed is dirty or contains a small amount of particles, a suitable cleaning agent or lubricant is injected into the unit to clean the sealing surface, in order to protect the sealing surface and ensure a reliable seal. (7) Widely used in food, medicine, petroleum, chemical, natural gas, steel, environmental protection, paper and other transmission pipeline media cut off or circulation. This device can also be injected with the appropriate cleaning agent or lubricant to clean the sealing surface.

Digital Laser Tape Measure

Mastergrip Laser Distance Meter

Product Description:

A laser distance measure is an advanced measuring tool to measure any distance without any efforts. It has a laser beam that is produced by the meter with the help of a battery and reflects it through a lens. The meter can measure the distance covered by the leaser and the result is shown on the display. Mastergrip laser distance meter is a digital distance measuring tool for precise and effortless measurement taking. It is an ideal measuring device for contractors, insurance adjusters, architects, flooring professionals and other people who do a lot of measuring. However, homeowners can easily use laser tape measures around the house, too.

User instruction:

Place the device on one end of what you want to measure, and then aim the laser beam so that it hits an object at the other end..If there's no wall, pole or anything like that, put a target at the spot you want to measure up to. The process is similar to using a conventional tape measure, except you use a laser beam instead of metal tape. Once you have the laser at the right spot, press the button, and the tape measure calculates the distance and displays it on its screen. The calculation is done through precision optics and laser physics using the phase-shift method, in which a laser hits an object and compares its reflection with the beam sent out, or using the time-of-flight method in which the time it takes for an optical pulse to reflect back is calculated. Some laser tape measures let you measure multiple distances and add them together automatically.
