The basic knowledge of the valve

Valve is used to control the valve body opening and closing parts of the opening to regulate the flow of media, the media pressure is reduced at the same time by virtue of the role of the pressure valve to adjust the opening and closing pieces of the opening and closing to maintain the valve pressure in a certain range , And in the valve body or after the injection of cooling water, the medium temperature decreases, this valve is called decompression valve. The characteristic of this valve is to keep the outlet hearing pressure and temperature within a certain range under the condition that the inlet pressure is constantly changing. Pressure relief valve according to the structure can be divided into film, spring film, piston, lever and bellows; according to the number of seats can be single-seat and two-seat; according to the location of the valve can be divided into positive Active and reactive. Pilot-type pressure reducing valve When the output pressure of the reducing valve is high or the diameter is large, the pressure is directly regulated by the pressure-adjusting spring, the spring stiffness must be too large. When the flow rate changes, the output pressure fluctuates greatly. The structure size Will also increase. To overcome these shortcomings, pilot-operated pressure relief valves can be used.

Cotton Buffing Wheels

Buffing Wheel is made of finely cotton cloth by special technology and is the precision polishing tools of metal and non-metallic workpieces,It is made of mutillayers 100% cotton cloth sewn surround by the center,with a leather lip attached around the inner hole. High quality material, exquisite workmanship, long service life.Specially used for polishing jewelry, ornaments, or precise products.

The layers of cloth edge with pile processing,suitable for metal, jewelry hardware,stainless steel, aluminum products, wood, plastic, ceramic, glass and watch industry grinding and polishing.

Working with polishing wax polishing effect is better.

Treated Buffing Wheels have a special chemical added to the cotton which gives them more aggressive cutting action allowing them to work faster than standard cotton spiral sewn buffing wheels. The chemical treatment also gives these buffs a longer lifespan.

Treated buffing wheels can be used in place of Cotton Spiral Sewn buffing wheels for cutting and coarse buffing.

Features:

-- Suitable for Metal, jewelry, metal, stainless steel, aluminum, wood, plastic.

-- Surface of the ceramic, glass and watches industry grinding and polishing.

-- Use with polishing wax polishing better.

-- Can be stacked onto tapered spindles for required thickness.
