JX29焊接式液面计拷克用于设备与测量系统的分割，即连接或断开设备与测量系统的联系，由于位置处于测量系统的起始处，所以称“根部阀”。液面计拷克理论上可以选用任意结构的阀门，在实际选用时以不与介质发生反应，动作不受介质影响，易密封，不易堵塞，少维护作为选用要求。

焊接式液面计考克

“焊接式液面计考克”是液位计管路中的一种专用截止阀。“考克”一词源自英文“Cock”的音译，在此特指一种结构紧凑、操作简单的直通式或三通式旋塞阀。其与设备本体的连接方式为焊接，故名焊接式考克。

焊接式液面计考克阀门通常由阀体、锥形塞芯（旋塞）和手柄组成。通过旋转手柄90度，带动塞芯转动，利用塞芯上的通孔与阀体通道的对齐或错位来实现流路的快速开启或切断。其核心作用是作为液位计的根部阀，用于隔离液位计、进行排污冲洗或更换仪表，是液位测量系统安全维护的关键部件。

焊接式连接确保了阀门口径与管道匹配，实现了很好密封、零泄漏，能承受更高的压力和温度，特别适用于高压、高温或对密封要求极高的危险工况。

焊接式液面计考克主要特点：

焊接连接： 无泄漏点，连接强度高，耐压性能好。

快速启闭： 只需旋转90度即可全开或全关，操作迅速。

流阻小： 直通式流道，流体阻力小，几乎不影响流量。

结构紧凑： 体积小巧，安装空间要求低。

密封稳定： 通过塞芯与阀体锥面的精密研磨配合实现密封，或采用柔性材料增强密封。

维护安全： 可安全地隔离液位计，实现系统不停车维护。

焊接式液面计考克典型应用：

主要用于石油化工、电力、锅炉压力容器等行业中与焊接式液位计（如玻璃板液位计、磁性液位计）配套使用，安装在压力容器与液位计之间的管路上。

Welded Level Gauge Cock Product Overview

The "Welded Level Gauge Cock" is a specialized shut-off valve used in level gauge piping. The term "考克 (Kǎo kè)" is a phonetic translation of the English word "Cock", referring here to a straight-through three-way plug valve with a compact design simple operation. It is termed "welded" because its connection to the vessel nozzle is made by welding.

This valve typically consists of a valve body, a tapered plug, a handle. By rotating the handle 90 degrees, the plug turns, the alignment misalignment of the hole in the plug with the passage in the body achieves quick opening shut-off of the flow path. Its core function is to act as the root valve for the level gauge, used to isolate the gauge, perform blowdown, flushing, facilitate gauge replacement. It is a critical component for ensuring the safe maintenance of level measurement systems.

The welded connection ensures perfect alignment with the pipeline provides absolute sealing with zero leakage, enabling it to withstand higher pressures temperatures. It is particularly suited for high-pressure, high-temperature, other critical applications leak-tightness is paramount.

Key Features:

Welded Connection: Eliminates leakage points, offers high connection strength excellent pressure resistance.

Quick Operation: Full open close achieved with a simple 90-degree turn, enabling rapid operation.

Low Flow Resistance: Straight-through flow path minimizes pressure drop has little impact on flow.

Compact Design: Small size requires minimal installation space.

Reliable Sealing: Achieved through precision lapping between the plug body's tapered surfaces, enhanced with resilient seals.

Safe Maintenance: Allows for safe isolation of the level gauge, enabling in-service maintenance without system shutdown.

Typical Applications:

Primarily used in industries such as petrochemical, power generation, boiler/pressure vessel applications. It is installed in the piping between the pressure vessel welded level gauges (e.g., glass level gauges, magnetic level indicators).
