油封式旋塞阀,DBB 旋塞阀

3Z Lubricated type plug valves (3Z 油封式旋塞阀):Designed for Crude oil,Oil,Natural gas handling and transmission lines.Line sealing is achieved basically by metal to metal contact between body and plug with assistance of sealant injected in between body and plug,which serves both sealing and lubricating during operation.

适用于运送原油,石油,天然气等煤气的管道上。密封方式是把润滑剂注射对阀体里面然后润滑剂引入到阀体和阀赛之间这样发挥紧密的密封作用

阀体里面,然后润滑剂引入到阀体和阀赛之间。这样发挥紧密的密封作用。Uniqueness of dynamically and pressure balanced design together with inverted plug design,assure prevention of locking ,which has been the problems of conventional design at higher pressure application.

压力平衡是跟阀赛款式一起来形成的。然后可以保证防止卡死现象。

3Z Double Block & Bleed (DBB) Valve(3Z 双关双断旋塞阀): Designed to meet Oil & Gas transmission, loading, unloading needs. Line

sealing is achieved by body and wedges cut from each side of the plug with or without the assistance of soft seat rings.

The sealing is positively made on each side of the plug(double block),and the media kept in the plug port area can be ), p p g p

abled into upstream or to the container to prevent from explosion .The Valve can be used for assuring metering accuracy and SCADA

systems.

设计为石油和煤气,装卸臂。管道密封是通过阀赛两方的两个滑板跟阀体紧密地接触可以得到。

密封是通过阀塞两方的两个滑板跟阀体紧密接触实现2密封是通过阀塞两方的两个滑板跟阀体紧密接触实现。

密封方式是通过阀塞两方安装的石墨(双关)和为了调整上下游之间的压力差安装的泄系统,可以防爆和保证计量站的计量精度及SCADA系统的信赖度。

NACE Construction Valves for Sour Gas Applications

NACE,the National Association of Corrosion Engineers,has published a report outlining acceptable materials for valves for sour service.The current outline is Publication MR0175-88,and is a guide to the manufacturers and users of valves based on the latest metallurgical knowledge.Most of our customers involved in this area of production also have their own specifications that may or may not be more stringent than the NACE publication.The reason for this is,of course, that the product varies from field to field and many different types of inhibitors are used.

The basic problem is that whenever even a small amount of hydrogen sulfide(H2S)is encountered in natural gas or under oil pressure,a corrosion phenomenon may occur,known as hydrogen sulfide embrittlement

or sulfide stress cracking.Actually,the steel part is absorbing hydrogen.This causes ductility,and when other stresses are added,may result in failure of the part.Currently,we know that some steels with yield strengths above90,000psi(621MPa)and/or hardness greater than Rockwell22(235Brinell)are subject to sulfide stress cracking. Failure below these limits is unlikely.

Because of a long history of reliability in numerous sour gas installations,Dynamic Balance valves can be supplied in conformance to standards enumerated in the NACE governing document on sour gas application.

In some cases,a more sophisticated construction may be required because of other corrosive elements in the flow stream.All major components are heat-treated to a controlled hardness of22or lower on the Rockwell C scale.In this construction,the plug is coated with electrolysis nickel to prevent galling.

Complete engineering details are available upon request.

2. Lubricated type plug valve 2-5. Stellite overlay

For high temperature and abrasive services,Dynamic Balance valves can be supplied with plug taper and body seat hard-surfaced with nickel or cobalt base alloys.These materials provide a protective coating having a low coefficient of friction for easier operation at elevated temperatures.p p

With additional hard-surfacing in high erosion areas,hard-surfaced Dynamic Balance valves provide excellent resistance to abrasion in coal,limestone,iron ore,copper ore and other water-carried slurries.For severe services,hard-surfacing extends valve life and improves valve performance significantly.

3Z Valves has extensive experience in applying hard-surfacing materials.controlled Special vacuum furnaces keep the base metal of the plug in a controlled,heated atmosphere where the coating alloy can be fused to base metal with optimum adherence.Fully trained technicians take the hard-surfaced plugs and lap these into the matching bodies.Valve assembly at room temperature is made with dimension allowances to assure proper operation at elevated temperatures in actual services.A valve shell test is performed to prove pressure containment,and a seat test is performed with normal adjustment seat to prove the integrity of the seat.To prevent stress cracking of the hard-surfacing material,these tests are performed at the valve maximum operating pressure.

2-5. 合金钢涂盖层

高温及恶劣的条件下使用:为了在高温及恶劣的环境下使用,3Z旋赛阀可以提供通过用镍和钴素材硬化处理的锥形阀赛和阀体。这类的素材可以涂盖层在高温度环境下。与此同时在容易腐蚀的地区下使用的硬化处理阀门可以提供对煤焦石灰石铁芯铜矿另外水带来的泥浆等物理阀门可以提供对煤焦,石灰石,铁芯,铜矿,另外水带来的泥浆等物质有恒优秀的抵抗能力。在严酷的环境下使用时,硬化处理阀门可以延长阀门的寿命的同时大得提高阀门的功能。

阀赛硬化处理:3Z拥有广泛的业绩。熟练技术人员把阀塞硬化处理后安装在阀体里面。指定的温度下装配的阀门在实际驱动的过程中可以发挥适当的功能。壳体试验可以证明在一定的条件下坚持压力和阀座试验证明在般调整下可以表现出完整的阀座为了证明硬化表面上的压力性明在一般调整下可以表现出完整的阀座。为了证明硬化表面上的压力性破裂,这种试验可以确认阀门最高的驱动压力。

3-1. General / Application

3Z Double Block&Bleed(DBB)Valve serve the following applications:

pipeline,liquid bulk terminals,aviation fueling,refining,oil/gas

production and custody transfer for the petroleum and oil and gas

industries

industries.

1.Metering Stations:Flow meters require calibration to verify their

accuracy.During meter calibration(proving),every closed valve in

the metering system must seal drop tight.Every3Z DBB valve in the

metering station can be quickly and easily shown to be holding leak-

tight.

2.Tank Farm:Fuel in storage tanks is exposed to the risk of

contamination and loss of volume unless the tank isolation valves can

be checked for zero leakage.Traditional gate valve will produce

constant loss of fuel from the open bleed.3Z DBB valves offer simple,

provable,tank-side isolation.

3.Loading/Unloading:Fuel loading/Unloading may require hundreds of

open/close strokes of the connection valves everyday.The valves

everyday

typically operate against full pump pressure on every stroke,and they

must close without leakage,Many loading/unloading facilities depend

on3Z DBB valves for safe,reliable,zero-leakage shut-off.

4.Multi-Product Manifolds:3Z DBB valve was developed for multi-

products fuel manifolds.Busy manifolds must be operated frequently,

manifolds frequently switching from product to product,often with power actuators and

sometimes without human supervision.Valves that can be trusted to

seal drop-tight,every time,will prevent the expensive consequence of

contaminated fuel.Liquid fuels that move through pipeline manifolds

are reliably segregated by provable,zero-leakage,3Z DBB.
