德國托普進(jìn)口鑄鋼絲扣球閥產(chǎn)品概述:
在西方國家工業(yè)發(fā)達(dá)的國家,球閥的使用正在逐年不斷的上升,在中國
,球閥被廣泛的應(yīng)用在石油煉制、長輸管線、化工、造紙、制藥、水利
、電力、市政、鋼鐵等行業(yè),在國民經(jīng)濟(jì)中占有舉足輕重的地位。球閥
只需要用旋轉(zhuǎn)90度的操作和很小的轉(zhuǎn)動力矩就能關(guān)閉嚴(yán)密。*平等的
閥體內(nèi)腔為介質(zhì)提供了阻力很小、直通的流道。通常認(rèn)為球閥zui適宜直
接做開閉使用,但近來的發(fā)展已將球閥設(shè)計(jì)成使它具有節(jié)流和控制流量
之用。球閥的主要特點(diǎn)是本身結(jié)構(gòu)緊湊,易于操作和維修,適用于水、
溶劑、酸和天然氣等一般工作介質(zhì),而且還適用于工作條件惡劣的介質(zhì)
,如氧氣過氧化氫,甲烷和乙烯等。球閥閥體可以是整體的,也可以是
組合式的。
應(yīng)用領(lǐng)域:
進(jìn)口鑄鋼絲扣球閥用于截?cái)嗷蚪油ü苈分械慕橘|(zhì),選用不同的材質(zhì),可分別適用于水、蒸汽、油品、液化氣、天然氣、煤氣、硝酸、醋酸、氧化性介質(zhì)、尿素等多種介質(zhì)。不僅結(jié)構(gòu)簡單、密封性能好,而且在一定的公稱通經(jīng)范圍內(nèi)體積較小、重量輕、材料耗用少、安裝尺寸小,并且驅(qū)動力矩小,操作簡便、易實(shí)現(xiàn)快速啟閉,球閥是近十幾年來發(fā)展zui快的閥門品種之一。
產(chǎn)品優(yōu)點(diǎn):
1、有zui低的流阻(實(shí)際上為零)。
2、 因在工作時(shí)不會卡住(在無潤滑劑時(shí)),故能可靠地應(yīng)用與腐蝕性介質(zhì)和低沸點(diǎn)液體中。
3、 在較大地壓力和溫度范圍內(nèi),能實(shí)現(xiàn)*密封。
4、 可實(shí)現(xiàn)快速啟閉,某些結(jié)構(gòu)的啟閉時(shí)間僅為0.05~0.1s,以保證能用于試驗(yàn)臺的自動化系統(tǒng)中。快速啟閉閥門時(shí),操作無沖擊。
5、 球型關(guān)閉件能在位置上自動定位。
6、 工作介質(zhì)在雙面上密封可靠。
7、 在全開和全閉時(shí),球體和閥座的密封面與介質(zhì)隔離,因此高速通過閥門的介質(zhì)不會引起密封面的侵蝕。
8、 結(jié)構(gòu)緊湊、重量輕,可以認(rèn)為它時(shí)用于低溫介質(zhì)系統(tǒng)的zui合理的閥門結(jié)構(gòu)。
9、 閥體對稱,尤其是焊接閥體結(jié)構(gòu),能很好地承受來自管道的應(yīng)力。
10、關(guān)閉件能承受關(guān)閉時(shí)的高壓差。

Cast steel wire ball valve
Germany top import cast steel wire buckle valve product overview:
In the western countries in the developed countries, the use of ball valves is rising year by year in China
, the ball has been widely used in oil refining, pipeline, chemical, paper, pharmaceutical, water conservancy
Electricity, municipal, steel and other industries, in the national economy occupies a pivotal position. Globe valve
Only need to rotate 90 degrees of operation and a small rotation torque can be closed tight. Compley equal
Valve body cavity provides a small resistance, through the flow channel. Ball valve is usually considered the most appropriate
The use of open and close, but the recent development has been designed to make it a throttle valve and control flow
Use. Ball valve is characterized by its own compact structure, easy operation and maintenance, suitable for water,
Solvents, acids and natural gas and other general working media, but also applies to poor working conditions of the media
Such as oxygen, hydrogen peroxide, methane and ethylene. Ball valve body can be whole, can also be
Combined.
Application of cast steel wire buckle ball valve:
The import of cast steel wire buckle ball valve is used to cut off or connected to the line of medium, use different materials, can be separay applied to water, steam, oil, liquefied petroleum gas, natural gas, coal gas, nitric acid, acetic acid, oxidizing medium, urea and other media. Not only has the advantages of simple structure, good sealing performance, but also in a certain range of nominal by small volume, light weight, less consumption of materials, installation of small size, and the driving torque is small, simple and easy to achieve rapid opening and closing, the valve is one of the fastest growing valve varieties in recent years.
Imported steel wire buckle ball valve product advantages:
1, there is a minimum flow resistance (in fact zero).
2, because not stuck at work (without lubricant), it can be reliably applied with the corrosive medium and low boiling point liquid.
3, in high pressure and temperature range, can be compley sealed.
4, can be quickly opened and closed, some of the opening and closing time is only 0.05 ~ 0.1s, to ensure that can be used for automated test system. Quick opening and closing valve, operation without impact.
5, ball off pieces can be automatically positioned at the position.
6, working medium in the two-sided reliable seal.
7, in the fully open and fully closed, the ball and seat sealing surface and the dielectric isolation, the high-speed media through the valve sealing surface will not cause erosion.
8, compact structure, light weight, can be considered for the most reasonable structure of the valve when it is low temperature medium system.
9, body symmetry, especially the welded body structure, can well withstand the stress from the pipe.
10, the closure of the device can withstand the pressure difference.
Technical parameters of imported steel wire buckle ball valve:
