2.Feature

CARX composite exhaust valve body for round barrel, including stainless steel ball valve body, valve stem and disc. This valve is installed in the pump outlet or send water distribution pipeline, set is used to eliminate the air in the tube, to improve the efficiency of the use of the pipeline and water pump, when once produced negative pressure tube, this rapid inhalation outside air valve, in order to prevent the pipeline damage due to negative pressure.

When tube began to water injection, the disc in the open position, a large number of exhaust, when the air line up, the full of water in the valve, floating ball up and drive the valve closed, stop the exhaust, when water tube is normal transportation, if there is a small amount of air within the valve to a degree, water levels fall in the valve, floating ball drops, the air is being exhausted from the holes. When the pump stops, the tube water empty or negative pressure in the tube, the plug head quickly open, inhalation of air, to ensure pipeline safety.

Q: the rest are hot, the living room outside all the heating pipe valve closed, the living room heating is still not hot, after the water for a while hot, and cold: There is gas, causing water not to cycle, give up on the cure! Are you single family control?Single family control, the general bedroom and living room is not all the way, the living room, this way, the vent valve in the toilet, I was on the road in the balcony! The bleeder valve, is made of copper tube in the device above two, as long as can step in his place, the bleeder valve with a small angle, feet above a needle, with a needle to drill a well, there is a long time not float, a gas exhaust out that leads to water circulation,Why do you put a little while, the water is hot, a little cooler, the water does not cycle, is dead water, can not cool it?I am building plumbing, believe me, yes, these are some common problems, especially on the top floor!

Q: What are the definitions of internal, external and leakage valves?: Upstairs to say there is a problem. The leakage within the valve that is the reason of erosion wear medium makes the valve is not closed tightly, even if the valve screw (stem) screwed in place, because there is still a gap between the spool and the valve body, the medium can flow past. Outside leakage generally refers to the valve and connecting flange or threaded connection between the seal and guide...

Q: For example, the knife gate valve, PZ73X-10C, DN50 torque is 5, torque is what role? What units?: The torque of the valve is the opening moment of the valve (valve torque): Newton meter.The opening moment, also known as the operating torque, is the most important parameter for selecting the valve actuating device. Opening torque is also a measure of the quality of the valve product is another important indicator, people in the evaluation of valve quality, commonly used valve opening light, flexible to describe it. In some advanced industrial countries in the pipeline valve standards, as one of the assessment indicators, and provides manual valve opening torque is not more than 360N ? M. More than this moment, it is necessary to consider the use of suitable driving devices (such as electric, pneumatic, hydraulic devices). Some manufacturers will open the torque printed in the product samples, user-friendly.

Q: The difference between fire general valve and fire fighting special valve: Fire fighting valves are mainly signal valves and alarm valves and water indicators, etc., other gate valves, butterfly valves, pressure relief valves and filters are common valves.

Q: What are the main equipments for valve production?: Press machine, CNC lathe, instrument lathe, drilling machine, machining center, assembly line, pressure test bench, plane, measuring instruments, etc.Valve (Famen) is a control component in the fluid delivery system. It has the functions of closing, adjusting, guiding, preventing reverse flow, stabilizing voltage, shunting or overflow and releasing pressure.Valves used in fluid control systems, from the simplest stop valve to a very complex automatic control system used in a variety of valves, a wide range of varieties and specifications. Valves can be used to control air, water, steam, a variety of corrosive media, mud, oil, liquid metal and radioactive media and other types of fluid flow. The valve according to the material is divided into cast iron valves, cast steel valves, stainless steel valves (201, 304, 316), chrome molybdenum steel, chromium molybdenum vanadium steel valves, valve, dual phase steel valves, plastic valves, non-standard customized valve material etc..

Q: What does "1/2" mean on the valve?: 1/2 is 4 points (20), 3/4 is 6 points (25), and 1 is 1 inches (32)

Q: How to check the quality of the valve?: First of all, to check the appearance of the valve is smooth and smooth. Cast valves without sand holes and obvious flaws. Forged valves check nominal pressure or pound level. Second, check the material of the valve, that is, the material composition, this is very important, the material does not meet the standard on the device will be a big problem. Finally, check that the switch is sensitive and the signs are clear. Test pressure is the last step.

Q: Where is the valve used?: Oil and gas pipelines, gas stations, gas stations, petrochemical plants, water plants, etc..The valve (Valve) is a mechanical device that controls the flow, flow, pressure, temperature, etc. of a fluid medium. The valve is the basic component of the piping system. Valve fittings are technically similar to pumps and are often discussed as a separate category. Valves can be operated by hand or hand wheel, handle or pedal, or by control to change the pressure, temperature and flow change of fluid medium. The valve can perform continuous or repeated operations on these changes, such as a safety valve installed in a hot water or steam boiler. In more complex control systems, automatic control valves are required depending on external inputs (i.e., regulating the flow through the pipe to the changing setting points). Automatic control valve without manual operation, according to its input and settings, so that the valve accurately control the requirements of fluid medium. The valve according to the material is divided into cast iron valves, cast steel valves, stainless steel valves, chrome molybdenum steel, chromium molybdenum vanadium steel valves, valve, dual phase steel valves, plastic valves, non-standard customized valve material etc..

Q: What are the ten major brands of China's valves?: Tianjin Gangyan guangheng special equipment Limited by Share Ltd is the leader Chinese special material valve industry, a joint venture with Chinese Gangyan established

Q: Can the angle valve of York central air conditioner be replaced by other valves?: Definitely. But I want you to tell me what you're doing, or give me a picture. I can give you some advice
