閥門分自動閥門與驅動閥門。自動閥門（如安全閥、減壓閥、蒸汽疏水閥、止回閥）是靠裝置或管道本身的介質壓力的變化達到啟閉目的的。驅動閥門（閘閥、截止閥、球閥、蝶閥等）是靠驅動裝置（手動、電動、液動、氣動等）驅動控制裝置或管道中介質的壓力、流量和方向。由于介質的壓力、溫度、流量和物理化學性質的不同，對裝置和管道系統的控制要求和使用要求也不同，所以閥門的種類規格非常多。劇不完全統計，我國的閥門產品品種已達四千多個型號，近四萬個規格，閥門在經濟生活中起著非常大的作用。

There are self-driven valves and operated valves. self-driven valves( like safety valve, relief valve, steam trap, check valve ) are functioning by utilizing its mechanical design or the pressure, direction of its flow medium.operated valve( like gate valve, globe valve, ball valve, butterfly valve ) is fuctioning by actuator( manual, electric, hydraulic, pneumatic etc. ) or the pressure , flow direction of its medium. due to the differences of pressure, temperature, flow, and physical-chemical character of its medium , there are different requirements in designing and applying the pipeline system.therefore there are numerous types of valve.according to an unofficial statistics, there are more than four thousand types of valve with approximately forty thousand specifications in China. Obviously, valve is an important element in the social economy.

steam traps to be "identified" steam and condensed water can play a role in blocking air drainage. "identification" and the condensed steam water based on three principles : the poor density, and temperature difference of change. So on the basis of three principles of creating three types of steam traps : classified as mechanical type, thermal static type, thermal power-based. 1. In the heat production equipment, drying room, rapid heat exchangers, distillation equipment needs rapid warming, not a condensed water heating equipment production should be chosen mechanical type steam traps. 2. In steam pipes, coupled heat pipelines, small heating equipment, heating equipment, air temperatures do not ask for the use of equipment, it should be the choice of hot static type steam traps. 3. Overheating in high-temperature high-pressure steam pipelines and equipment, should choose an exclusive steam traps steam.

balancing valve dynamics operating principles : through changes in the flow Disc balancing valve the area around the valves to adjust to the change, thus achieving the purpose of flow control. Is a dynamic balancing valve local resistance to change spending components. When balancing valve and differential pressures are smaller than the smallest start differential pressures were not compressed spring-loaded, the largest circulation area. When balancing valve and differential pressures beyond the scope of work is completely compressed spring-loaded valves guts, guts flow only from valves on both sides of the square shed, when valves guts into a fixed regulator, the flow and differential pressures in proportion with the increase and differential pressures increase. balancing valve have some great pressure within the air-conditioning equipment to limit the maximum flow, automatic constant flow characteristics, in the large-type, complex, air conditioning load is not constant heating works, a simplification of the system into debugging, and shorten the debugging time.

throttle valve as expansion valves, regulating valves, it is refrigeration system indispensable four one important equipment. throttle valve role is the export of high-pressure liquid coolant condensers to reduce and regulate the flow of relief. Coolant liquid after throttle valve expenditure of relief after a low-temperature low-voltage gas liquid mixed fluid, after separation into ammonia liquid separation devices for invalid after steam vaporizer, to evaporation endotherm. throttle valve many patterns, structures also vary, but their basic principles are that the high-pressure liquid coolant forced to adapt to the system through a flow "puncture wounds on the" make it through the puncture wounds on the need to overcome the considerable resistance movement, resulting in fusion pressure, and at the same time, some liquid into steam, and from its own lessons vaporization latent heat, thereby expanding the gas into liquid cryogenic fluid mixed low voltage state. throttle valve the Faxin for needle-shaped cone or belt gaps Cone, the thread for Fagan small teeth, when round-hand, the distance is Faxin mobile, liquid through the area is small, this can cause considerable local resistance, high pressure liquid through the puncture wounds on the consumption of energy and relief. throttle valve opened degrees is based on the size of the evaporator heat load changes that will be open for its usual hand for the eighth round to fourth week and not more than one week, otherwise spend big opening, lost spending.

Hydraulic valves of a wide variety, in addition to different varieties, specifications generic valves, there are many specialized valves and complex devices. Hydraulic valves on the basic types, classified according to the following manner : by functional classification 1. Hydraulic pressure control valves used to control the hydraulic pressure system flow valves. 2. Flow control valve hydraulic system used to control the flow of hydraulic valves Ye Liu. 3. Hydraulic control valves used to control the direction of the system flow mobile hydraulic valves direction. In addition to the overall function of a single hydraulic valves, hydraulic valves and a number of specialized hydraulic valves with more complex functions, such as pressure control can only control the direction or control which can control the direction of flow, and so on.

Controlled manner by classification 1. Constant control valves or switches such hydraulic valves through hands-off type of electro-magnet or transfer institutions, will valve disc location of the spring-loaded or valve disc set in a working condition so that flow pressure, or flow to maintain a certain flow value. This hydraulic valves are the most common ordinary hydraulic valves. 2. Proportional control valves such devices export volume (flow, pressure) can be imported in accordance with the law of change in the continuous signal proportional to regulate. They often use imported electrical signal proportional electro-magnet will be converted into mechanical power or valves displacement volume control. Can also use other forms of electrical control devices. Because of valves structure simple, reliable work, the lower the price, performance than ordinary constant control valves have markedly improved, and through continuous electrical signal control, and therefore, on many occasions, gained widespread application.

蝶閥[BUTTERFLY VALVE]
蝶閥是用隨閥桿轉動的圓形蝶板作啟閉件,以實現啟閉動作的閥門.蝶(die)閥主要(yao)用(yong)截斷閥使用(yong),亦可設(she)計成具有(you)調(diao)節(jie)或截斷兼調(diao)節(jie)的(de)功(gong)能.目(mu)前蝶(die)閥在(zai)低(di)壓大中口(kou)徑管道上的(de)使用(yong)越來越多(duo)

Butterfly valve is on/off by the turning of the stem which operate the round butterfly disc. It is mainly used as cut-off valve and also can be designed as regulating or cut-off / regulating combined valve. currently , butterfly is mainly used in the low pressure large size pipelines.

蝶閥的蝶板安裝于管道的直徑方向。在蝶閥閥體圓柱形通道內，圓盤形蝶板繞著軸線旋轉，旋轉角度為0°~90°之間，旋轉到90°時，閥門則牌全開狀態。

butterfly valve panels installed at the Tip of the diameter pipeline direction. In butterfly valve body flight corridors, the disc-shaped Tip boards around rotary axis, rotation angle for 0° -90 meridian east between rotary to +90, the valves are open all licence conditions.

蝶閥結構簡單、體積小、重量輕，只由少數幾個零件組成。而且只需旋轉90°即可快速啟閉，操作簡單，同時該閥門具有良好的流體控制特性。蝶閥處于完全開啟位置時，蝶板厚度是介質流經閥體時唯一的阻力，因此通過該閥門所產生的壓力降很小，故具有較好的流量控制特性。蝶閥有彈密封和金屬的密封兩種密封型式。彈性密封閥門，密封圈可以鑲嵌在(zai)閥(fa)體(ti)上或附在(zai)蝶板(ban)周邊。

butterfly valve structure simple, small size, light weight, only by a few parts. But it can be rapidly open and close-90E, simple to operate, while the fluid control valves have good character. butterfly valve a fully open position, Tip board thickness is only when the medium flows through body resistance, the pressure generated by the air valves small, it has a better flow control characteristics. butterfly valve a metal shells sealed and the two sealed sealed patterns. Flexible sealed valves, seal ring can embed in body or peripheral board, , s to Tip.
