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、截止阀应用于高温、高压介质的管道或设备。例如火力发电厂、核电站、石化系统的高温、高压管道。

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、管道对流阻要求不严格的管道。也就是说，压力损失考虑不大。

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

3、良工阀门厂家告诉你，针阀、仪表阀、取样阀、压力计阀等可用于小型阀门。

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

4、有流量调节或压力调节，但对调节精度要求不高，管道直径相对较小，如公称通过≤管道50mm，宜选用。

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、在合成工业生产中，应选择公称压力PN160公称压力16MPa或PN320公称压力32MPa的高压角截止阀或高压角节流阀。

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、在氧化铝拜耳法生产的脱硅车间和易结焦的管道中，很容易选择直流截止阀或直流节流阀，阀体分离，阀座可去，硬质合金密封副。

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、在城市建设中的供水供热工程中，可以选择截止、平衡阀或柱塞阀作为公称通经小于150毫米的管道，公称通过小于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.

在打开和关闭过程中，阀瓣与阀体密封面之间的摩擦力小于闸阀，因此具有耐磨性。开启高度一般只有阀座通道直径的1/4，所以比闸阀小很多。通常阀体和阀瓣上只有一个密封面，因此制造工艺更好，易于维护。公称压力或压力级：PN1.0-16.0MPa、ANSICLASS150-900、JIS10-20K；选用不同的材料，可分别用于水、蒸汽、油、硝酸、醋酸、氧化介质、尿素等多种介质。

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.
