2、结构紧凑、体积小、刚性好、密封可靠;

3、关闭件(闸板)采用弹性结构，在工作中能自动补偿由于异常负荷或温度引起的阀体变形。因此，密封可靠，并且不会产生闸板楔柱;

4、公称通径大于等于NPS1011，压力级400磅级和公称通径大于等于NPSS611、压力级150～2500磅级的手动阀门，其操做装置中配有滚动轴承，启闭轻松;

5、主体材料、内件材料、填料、垫片、紧固件的材料可根据用户要求或实际工况条件合理组合;

6、阀座可为更掀式阀座，可任意组合与关闭密封面材质配对，以符合工况要求，延长使用。

1、 Introduction to imported American standard gate valves

The design and manufacture of imported American standard gate valve meet the requirements of American national standard ANSI B16.34, American Petroleum Institute standard API6D and API600; American standard flange gate valve has compact structure, small volume, good rigidity and safe and reliable sealing. The materials of main body, internal parts, fillers, gaskets and fasteners can be reasonably combined according to the user's requirements or actual working conditions. It is suitable for cutting off or connecting pipeline medium in petroleum, chemical, hydraulic and thermal power plants with nominal pressure of pn1.6 ~ 16.0mpa and working temperature of - 29 ℃ ~ 550 ℃. The applicable media of American standard gate valve are: water, oil, steam, acid, alkali, ammonia, urea, sulfur-containing natural gas, etc. the operation modes of American standard flange gate valve are: manual, gear drive, electric, pneumatic, etc.

2、 Technical parameters of imported American standard gate valve:

Nominal diameter: 2 "- 36"

Nominal pressure: 150lb-2500lb

Applicable temperature: - 30 ℃ - 425 ℃

Applicable media: water, oil, steam, acid and alkali

Body material: cast iron, cast steel, carbon steel, stainless steel

Connection mode: flange connection

Transmission mode: manual, worm gear

3、 Working principle of imported American standard gate valve:

American standard gate valve and flange gate valve belong to the same type of valve. The difference is that its closing part is a ball. The ball rotates around the center line of the valve body to open and close the valve. Gate valve in the pipeline is mainly used to cut off, widely used as a new type of valve, this kind of valve in the pipeline should generally be installed horizontally.

4、 Performance characteristics of imported American standard gate valve:

1. Product design standard ansib16.34, standard ap16d and API600;

2. Compact structure, small volume, good rigidity and reliable sealing;

3. The closing part (gate) adopts elastic structure, which can automatically compensate the deformation of valve body caused by abnormal load or temperature. Therefore, the sealing is reliable and the ram wedge will not be produced;

4. For manual valves with nominal diameter greater than or equal to nps1011, pressure class 400 and nominal diameter greater than or equal to npss611, pressure class 150-2500, rolling bearing is equipped in the operating device, which makes it easy to open and close;

5. The materials of main body, internal parts, fillers, gaskets and fasteners can be reasonably combined according to the user's requirements or actual working conditions;

6. The valve seat can be a more lift type valve seat, which can be matched with the material of the closing sealing surface at will, so as to meet the requirements of working conditions and prolong the service life.
