How We Get That Gas Tight Seal

How We Get That Gas Tight Seal

没有气阀, the natural gas distribution process wouldn’t be as efficient and safe as it is today. In addition to controlling gas flow within a structure, these lifesavers are also considered the primary shut off for meter service, which is largely due to their gas tight seal.

There are two common gas valve types – 球塞. At 澳门葡京赌场赢钱技巧, both are made of an iron body with brass components while being designed and tested to comply with ANSI/ASME B16.33 American National Standard for Manually Operated Metallic Gas Valves for use in Gas Piping Systems up to 175 PSIG.

While the two gas valve types both were created for the same PSIG, 温度范围, 旋转范围, they differ when it comes to their source of seal. 对于旋塞阀, grease is the main component as it’s used to occupy/fill the small space/void that is between the brass plug and the body of the valve. Should additional grease be required to maintain the seal, the plug valves are designed so that they can be re-lubricated. Due to this fact, the plug valve is often referred to as a maintenance valve. The ball valve prevents leakage to the atmosphere or through the valve by way of port seals. The brass ball rides between two PTFE port seals for its leak protection and does not require lubrication.

Properly maintaining a gas valve can ensure that it lives up to its highest potential. Continue reading to learn more about the maintenance required in order to guarantee the great sealing component these gas parts are known for.

清除
In relation to the high pressure gas industry, ‘purging’ is an act of protecting your service line and lubricated plug valve or ball valve from air pockets and any potential debris or contaminants. This is done before service is turned on, as the presence of any unwanted debris or contaminants could damage the regulator and even the meter.

Improper purging of the gas line can mean that, in addition to damaging the regulator and/or meter, you can also end up damaging the gas valve. 例如, 带球设计, this can damage the PTFE port seals, which can cause a leak and may require replacement. 采用插头式设计, this risks blowing nearly all the grease out, meaning a need for re-lubrication.

澳门葡京赌场赢钱技巧 highly recommends an expert to perform the purging if that’s the route you’ve decided to take. Get a break down on how to purge properly by viewing the video below.

再润滑
As previously mentioned, re-lubrication may be required for plug valves that leak through in the closed position. This could be the result of the grease being wiped away or drying up. Causes of this can be due to the age of the valve (20-30 years), having been cycled multiple times, or through the use of purging (如上所述) 服务热线. In the event that a valve does need to be re-lubricated, 澳门葡京赌场赢钱技巧有 re-lube工具 and cartridges so customers can always be prepared while in the field.

It is no secret that the success of the high pressure gas industry greatly depends on the safety and security of providing natural gas to a structure. This is why gas valves are so essential to the process. While no one type of valve is better than the other, they are only as effective as the utility maintaining their gas tight seal.
