High temperature globe valve refers to a valve with a closing component (disc) that moves along the centerline of the valve seat. According to the movement of the valve disc, the change in the valve seat opening is proportional to the valve disc stroke. Due to the relatively short opening or closing stroke of the valve stem of Lianggong valve manufacturers, this type of valve has a very reliable cutting function, and the change in the valve seat opening is proportional to the stroke of the valve disc, making it very suitable for regulating flow. So, this type of valve is very suitable for cutting, regulating, and throttling.

1、截止閥應(yīng)用于高溫、高壓介質(zhì)的管道或設(shè)備。例如火力發(fā)電廠、核電站、石化系統(tǒng)的高溫、高壓管道。

1. Stop valves should be used in pipelines or equipment with high-temperature and high-pressure media. For example, high-temperature and high-pressure pipelines in Fossil fuel power station, nuclear power plants and petrochemical systems.

2、管道對(duì)流阻要求不嚴(yán)格的管道。也就是說(shuō)，壓力損失考慮不大。

2. Pipelines with less stringent requirements for flow resistance. That is to say, the consideration of pressure loss is not significant.

3、良工閥門廠家告訴你，針閥、儀表閥、取樣閥、壓力計(jì)閥等可用于小型閥門。

3. Lianggong valve manufacturers tell you that needle valves, instrument valves, sampling valves, pressure gauge valves, etc. can be used for small valves.

4、有流量調(diào)節(jié)或壓力調(diào)節(jié)，但對(duì)調(diào)節(jié)精度要求不高，管道直徑相對(duì)較小，如公稱通過≤管道50mm，宜選用。

4. There is flow regulation or pressure regulation, but the requirement for regulation accuracy is not high. The diameter of the pipeline is relatively small, and if the nominal diameter is ≤ 50mm, it should be selected.

5、在合成工業(yè)生產(chǎn)中，應(yīng)選擇公稱壓力PN160公稱壓力16MPa或PN320公稱壓力32MPa的高壓角截止閥或高壓角節(jié)流閥。

5. In the production of synthetic industries, high-pressure angle globe valves or high-pressure angle throttle valves with a nominal pressure of PN160, 16MPa, or PN320, 32MPa should be selected.

6、在氧化鋁拜耳法生產(chǎn)的脫硅車間和易結(jié)焦的管道中，很容易選擇直流截止閥或直流節(jié)流閥，閥體分離，閥座可去，硬質(zhì)合金密封副。

6. In the desilication workshop produced by the Bayer process process of alumina and the pipeline prone to coking, it is easy to choose DC stop valve or DC throttle valve. The valve body is separated, the valve seat is removable, and the cemented carbide sealing pair is available.

7、在城市建設(shè)中的供水供熱工程中，可以選擇截止、平衡閥或柱塞閥作為公稱通經(jīng)小于150毫米的管道，公稱通過小于150毫米的管道。

7. In the water supply and heating engineering of urban construction, cut-off valves, balance valves, or plunger valves can be selected as pipelines with a nominal diameter of less than 150mm and a nominal diameter of less than 150mm.

在打開和關(guān)閉過程中，閥瓣與閥體密封面之間的摩擦力小于閘閥，因此具有耐磨性。開啟高度一般只有閥座通道直徑的1/4，所以比閘閥小很多。通常閥體和閥瓣上只有一個(gè)密封面，因此制造工藝更好，易于維護(hù)。公稱壓力或壓力級(jí)：PN1.0-16.0MPa、ANSICLASS150-900、JIS10-20K；選用不同的材料，可分別用于水、蒸汽、油、硝酸、醋酸、氧化介質(zhì)、尿素等多種介質(zhì)。

During the opening and closing process, the friction between the valve disc and the sealing surface of the valve body is less than that of the gate valve, so it has wear resistance. The opening height is generally only 1/4 of the diameter of the valve seat channel, so it is much smaller than the gate valve. Usually, there is only one sealing surface on the valve body and disc, so the manufacturing process is better and easier to maintain. Nominal pressure or pressure level: PN1.0-16.0MPa, ANSICLASS150-900, JIS10-20K; Different materials can be used for various media such as water, steam, oil, nitric acid, acetic acid, oxidizing medium, urea, etc.
