Q:How to open the gas valve with drawings
1, according to the routine, now the handle position shows that the valve is open.2, if the handle rotated 90 degrees, the gas pipeline gas has no change, should be the stem slipped, can not drive the valve ball rotation. Try rotating several times. If it still doesn't work, ask a professional to check it out.
Q:HH valve company in the United Kingdom, how about the valve?
Our factory boiler has this brand of valve, used for many years, has been no problem, really good.
Q:1/2, what does 1/4 valve mean? I don't understand. What does this number mean?
I have to answer a simple 1/2 1/4 is American Standard valve diameter to the national standard to calculate it is 1/2=DN15 1/4=DN8Also on the valve size of the meaning of the Wenzhou essence valve factory for you to answer
Q:What does the valve QF mean?
Valve type, one of the contents, Q refers to the ball valve, F refers to the F-4 seals.
Q:Chinese valve and a valve which is better?
Look what valve you use, ah, these two can be ah!
Q:What are the types of valves?
1.2.3 classification by body materialx09 (1) non-metallic material valves: such as ceramic valves, glass fiber reinforced plastic valves, plastic valvesx09 (2) metal valves: such as copper alloy valves, Aluminum Alloy valves, lead alloy valves, titanium valves, Monel alloy valves, cast iron valves, carbon steel valves, cast steel valves, low-alloy steel valves, high alloy steel valves.x09 (3) metal body lining valve: such as lining lead valve, lining plastic valve and lining enamel valveHa ha, I answered it only a while ago
Q:What is the valve?
valveDefinition of scientific and technical termsValveEnglish Name: valvevalveValve 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.Definition 1: a device used to control flow in a pipe.Subject: electricity (first level discipline); hydraulic construction (two disciplines)Definition 2: equipment installed in a pressure pipe to control the flow of water.Subject: Water Conservancy Science and Technology (first level discipline); hydraulic construction (two disciplines); gate and hoist (three disciplines)Valve historyThe valve is produced with the flow of the pipe. Human valves have been used for nearly 4000 years. In ancient China from the brine well absorb salt brine, once in a bamboo pipe used in cork valve. In the 1800 BC, the ancient Egyptians used similar wooden cocks to control the distribution of water to build large water conservancy projects to prevent the Nile from overflowing. These are the embryonic form of the valve. The extensive use of industrial valves began only after Watt invented the steam engine. In the early twentieth Century, there were valves of cast steel, wrought steel and forged welded joints.
Q:Which valves are used in the power station?
Power gate valve, also known as power station valve, is mainly used in various pipelines of fire power plants, cutting off or connecting pipeline medium.Applicable medium: non corrosive media such as water and steam. Compared with other valve products, the valve is characterized by high temperature and high pressure and unique self sealing design. The higher the pressure, the more reliable the seal is. Because of its performance, technical characteristics and special working conditions, the products can not be replaced by other products.Compared with other valve products, the gate valve of the power station is characterized by high temperature and high pressure. If only the pressure is lower than that of the universal valve, the temperature is lower than that of the general valve. Because of its performance, technical characteristics and special working conditions, the products can not be replaced by other products.
Q:What do letters represent in the QF-2 and PX-32 valve models?
Other letters of the valve indicate explanations and regulations! You never ask again when you ask again!
Q:In the fire drawing, what valve does the following valve represent?
1, fire drawings, the following valve signal valve and alarm valve.2 、 signal valve is the best matching product of automatic fire sprinkler system. The structure characteristics and working principle: the top design electrical device the butterfly valve of the worm and the worm gear driving device, and with the stem straight connecting transmission. In the closed precision electromechanical device, opening mechanical instructions and imported electrical components and parts with rust proof valve. The output signal is stable and reliable for a long time.3 、 alarm valve products are wet alarm valve, dry alarm valve, rain alarm valve, pre acting alarm valve and so on. It is the core component of wet automatic sprinkler system. The water enters from the bottom of the valve body and closes the check valve through the dead weight inside the valve body to form a standby system with water pressure. The high pressure gauge indicates the system pressure, and the low pressure gauge indicates the pressure outside the system. When the protected area fire, high temperature make the nozzle temperature sensing element of blast nozzle sprinkler system, pressure drop, the valve opens, water flows continuously into the system, the nozzle opening, continuous sprinkler. At the same time, a small amount of water enters the alarm tube from the inner hole of the valve seat, passes through the filter, the retarder, and then pushes the hydraulic alarm to alarm. In addition, after the pressure switch is activated, the electrical signal is issued and the make-up water is started.
We have advanced technologies, facilities, resources and talented personnel for processing, developing, studying, designing and manufacturing of different kinds of valves. Our main products are wafer and lug type butterfly valves, slim pinless butterfly valves, flanged valves, gate valves, check valves, ball valves, and Y-strainers in medium and low pressure rate. Our valves are widely applied to water draining, power generation, petroleum, chemical industry, heat supply, metallurgy, medicine, and grocery, as the throttling and shutting-off equipment.
