Technical Advantages

1）Large internal flow channel area;

2）There is no external power source, the protection action is reliable, and adjustments can be made without stopping production;

3）The closing slide valve adopts double sealing, which is safe and reliable;

4）The casing material meets the SY/T 0599-1997 anti-sulfur standard;

5）All internal control components are made of stainless steel;

6）With a simple structure, this safety protection device can be installed on the tee position of the existing natural gas wellhead device;

7）This safety protection device has no throttle orifice, so it is not necessary to replace the orifice. Users can adjust and protect the initial gas volume according to the gas well’s output;

8）Additional function 1: Ultra-high pressure protection function (upper limit of pressure: 10MPa)

9）Additional function 1: Ultra-low pressure protection function (lower limit of pressure: 0-0.5MPa)




Product introduction

The gas well head protector is a safety protection device installed on the outside of the production gate valve of the gas wellhead and used for natural gas transmission pipelines. If accidents such as pressure loss due to breakage and leakage happen to natural gas transmission pipelines, this device can automatically cut off the gas source at the wellhead in time to prevent further accidents. Thanks to the participation of a number of technical backbones and fund investment for a long time, it has become one of the company’s mature products and also our company’s patented product. Our company can also add customized ultra-high pressure protection (over-pressure protection) and ultra-low pressure protection (under-pressure protection) functions to meet customer needs based on the original mechanical automatic protection function according to user needs.

The safety protection device of natural gas pipelines can be divided into two types according to the structure: Adjustable type and throttling type. At present, the most widely used safety protection device is the adjustable safety protection device, which can continuously adjust and protect the flow.
