Precision machining bathroom bubble valve body

Valve also known as cut-off valve valve, belongs to compulsory seal valve, so valve is closed in the must to the valve pressure to force the sealing surface leakage. When the medium from the bottom of the valve into the valve, the operating force required to overcome the resistance, is the stem and the packing of the friction and thrust generated by the medium pressure, than the valve off the valve opening force, therefore, the diameter of the stem to a large, otherwise it will top curved stem failure occurred. According to the connection mode is divided into three types: flange connection, threaded connections, welded connections. The emergence of self sealing valve, cut-off valve of the flow direction of the medium is replaced by the top of the valve into the valve chamber, then in the medium under pressure, force of the valve off a small, and the valve of the force is large, the stem diameter can be reduced accordingly. At the same time, in the role of the media, this form of valve is also more rigorous. China's valve "three to" has been provided, the flow of the cut-off valve, will be used from top to bottom. When the valve is turned on, the opening height of the disc is 30% to 25% of the nominal diameter. The flow rate has reached the maximum, indicating that the valve has reached the full open position. So the full open position of the valve should be decided by the stroke of the valve.

Cutoff (stop valve, globe valve) valve opening and closing parts are plug shaped valve, sealing the upper surface is level or sea surface, the valve flap along the centerline of the valve seat for linear motion. Stem form of exercise (generic name: dark bar), but also lift rotating rod can be used to control air, water, steam, all kinds of corrosion medium, mud, oil, metals and radioactive liquid medium of various types of fluid flow. Therefore, this type of cut-off valve is very suitable as a cut-off valve and throttle valve. Due to the valve stem to open or close the trip is relatively short, and has very reliable cut-off function, and because changes in the valve seat through the mouth of the valve stroke is proportional to, very suitable for in the regulation of the flow.

Gate valve (gate valve) is a opening and closing the gate assembly, perpendicular to the direction of movement and direction of flow of the gate, gate valve can be fully open and fully closed, discomfort door parameter varies, usually 5 degrees, the medium temperature is not high for 2 ~ 52 '. Improve the process, make up the sealing surface angle in the process of the deviation, which is called the gate

Manual gate valve working principle: turn the hand wheel, through the hand wheel and the stem of the thread into the back, enhance or decrease the valve plate connected with the stem, to achieve the role of opening and closing.

According to the shell / main material classification, gate valve can be divided into:

Metal material valve: such as carbon steel valves, alloy steel valves, stainless steel valves, cast iron valves, titanium valves, Monel valves, copper alloy valves, lead alloy valves.

Metal body lining valves: such as rubber lined valves, fluorine lined valves, lined with lead valves, plastic lined valves, lined with enamel valves.

Non metallic materials, such as ceramic valves, glass valves, plastic valves.

Light weight: the body is made of high ductile cast iron, the weight is less than the traditional weight of about 20%~30%, convenient installation and maintenance.

Flat gate seat: the traditional valve often in the watering tube after washing due to foreign objects such as stone, wood, cement, iron, and other debris deposited on the valve at the end of the groove, easy to cause the cannot be closed tightly and the formation of water leakage, elastic seat sealing gate valve at the bottom of the and the water machine with flat design, not easy to cause debris deposition, so that smooth flow of fluid.

Overall package plastic: gate adopts high-quality rubber overall, the outsourcing of plastic, Europe's leading rubber vulcanization technology makes vulcanization after the gate to ensure accurate geometry and rubber and ductile cast gate then solid, not easily fall off and good elastic memory. water

Casting valve: valve body casting, precise geometry makes the inside of the body without any finishing can ensure that the valve seal.
