水阀

The solution of problems such as water hammer,hard to dispose the noncondensables, air lock and selection of steam trap were discussed to save energy,protect environment and lower the cost.

指出蒸气凝结水回收的重要性的同时对炼油厂蒸气凝结水回收系统中存在的诸如水击、非凝结性气体不能排除、气阻及疏水阀的选型安装等问题的解决办法进行了探讨。

Series of orveheat steam trap,Utilizing the principle of buoyance,auxiliary valve can fluctuate in the pipe mouth .

系列过热蒸汽疏水阀采用集水池的方式，副阀利用浮力原理，可以在进气管口上下浮动。

Open the relevant water intake valves and the discharge valve on the pipe line.

打开管路上的进水阀和排出阀。

Due to the fact that the valve seat hole of free-ball float trap is always below the level of condensed water, ultimately formed water seal that separated water and steam in a natural way, therefore, there should be in no circumstance of leakage of steam during operation of the equipment.

由于自由浮球式疏水阀的阀座孔总处于凝结水液位以下，形成水封，水汽自然分离，工作时达到无蒸汽泄漏。

Equipment has just started work, the air tube through the Y series automatic air unit exhaust emission, low-temperature condensation water to enter the trap, the condensation of water level rise, float up, valve open, the rapid discharge condensate, steam fast access to equipment, equipment, rapid warming, Y series automatic row of air temperature sensing devices, liquid expansion devices automatically turn off the air row.

设备刚启动工作时，管道内的空气经过Y系列自动排空气装置排出，低温凝结水进入疏水阀内，凝结水的液位上升，浮球上升，阀门开启，凝结水迅速排出，蒸汽很快进入设备，设备迅速升温，Y系列自动排空气装置的感温液体膨胀，自动排空气装置关闭。

The project area has three shopping malls in a row not to fight the fire area, with a total length of the circumference of more than 1 / 3, Road fire engines from the inside edge of the wing wall construction materials to highlight the edge of not less than 5.00m, and fire engines to meet the Road Fire The largest car turning radius of 12m, to fight the fire site with a width of 18m, and this is not tall tree planting; and fire fighting facilities of not more than 5% of the slope, fire engines, fire fighting facilities should be able to carry a large set of fire engines Weight; Combined air-conditioning unit: for department stores, supermarkets, large bays, such as the lobby room, a new unit set up wind, ventilation and air return, setting up a new, back to the wind and the proportion of exhaust valve, according to the outdoor temperature of the new regulation, the ratio of air return, Back to the water main unit based PI control valve and in accordance with return air-conditioning temperature valve opening.

本项目商场三个面设有不连续消防扑救面，总长度大于周长的1/3，消防车道内边路缘距建筑外墙突出物边缘不小于5.00m，且消防车道满足消防车最大12m 的转弯半径，消防扑救场地的宽度为18m，且此范围内没有种植高大乔木；此外消防扑救场地的坡度不大于5%，消防车道、消防扑救场地应能承载大型消防车的载重量；组合式空调机组：用于百货商场、超市、大厅等大开间房间，机组设新风、回风及排风，设新、回风及排风比例调节阀，根据室外温度调节新、回风比例，机组回水管设比例积分调节阀并根据回风温度调节水阀开度。

For accelerating the development in China, Invensys Controls has set up an APAC headquarters in Shanghai. At the same time, there are three wholly-owned subsidiaries under Invensys Controls: Ranco Changzhou, Invensys Controls Qingdao and Invensys Controls Weihai. They are the professional manufacturers for Air Condition Revising Valve, Temperature Controller for Refrigeration, Defrost Timer and Electronics Controller; Power Modulator for Kitchen; Electronical and Mechanical Controller for Cloth Washer and Dish Washer, Water Valve, Electronics Controller and Pressure Switch, etc.

为推动中国市场的发展，英维思控制系统将亚太区的总部设在上海，同时，控制系统中国区下属的三家独资企业：常州兰柯四通阀有限公司，英维思控制器有限公司和威海英维思控制器有限公司，分别专业化生产空调用四通阀；冰箱、冰柜用温控器、化霜定时器和电子控制器；厨具用能量调节器；洗衣机、洗碗机用机电程控器、水阀、电子控制器和压力开关等产品。

When the cold weather, long-closed In-line pumps stop valve, the valve should rule out stagnant water.

天气寒冷时，闸阀水阀长期闭停，应将阀后积水排除。

Steam traps, condensate piping one of the main accessories, play the role of blocking water and exhaust.

疏水阀是蒸汽、凝结水管道系统的主要附件之一，起阻水和排气作用。

Traps should be installed in the device's minimum Export Department, promptly discharge condensate, steam piping to avoid resistance.

疏水阀应安装在设备出口的最低处，平衡阀及时排出凝结水，避免管道产生汽阻。
