進(jìn)口法蘭球閥工作原理：

進(jìn)口法蘭球閥開啟過(guò)程：

1在關(guān)閉位置，球體受閥桿的機(jī)械施壓作用，緊壓在閥座上。

2當(dāng)逆時(shí)針轉(zhuǎn)動(dòng)手輪時(shí)，閥桿則反向運(yùn)動(dòng)，其底部角形平面使球體脫開閥座。

3閥桿繼續(xù)提升，并與閥桿螺旋槽內(nèi)的導(dǎo)銷相互作用，使球體開始無(wú)摩擦地旋轉(zhuǎn)。

4直至到全開位置，閥桿提升到極限位置，球體旋轉(zhuǎn)到全開位置。

進(jìn)口法蘭球閥關(guān)閉過(guò)程：

1關(guān)閉時(shí)，順時(shí)針旋轉(zhuǎn)手輪，閥桿開始下降并使球體離開閥座開始旋轉(zhuǎn)。

2繼續(xù)旋轉(zhuǎn)手輪，閥桿受到嵌于其上螺旋槽內(nèi)的導(dǎo)銷的作用，使閥桿和球體同時(shí)旋轉(zhuǎn)90°。

3 快要關(guān)閉時(shí)，球體已在與閥座無(wú)接觸的情況下旋轉(zhuǎn)了90°。

4手輪轉(zhuǎn)動(dòng)的zui后幾圈，閥桿底部的角形平面機(jī)械地楔向壓迫球體，使其緊密地壓在閥座上，達(dá)到*密封。

Inlet flange ball valve working principle:

Inlet flange ball valve opening process:

1 in the closed position, the ball by the stem mechanical pressure, pressure on the seat.

2 when the handwheel counterclockwise, the stem is the reverse movement, the bottom of the angular plane to disengage the ball seat.

3 stem continues to rise, and with the stem spiral groove guide pin interaction, so that the ball began to spin without friction.

4 until fully open position, the valve stem to the limit position, the ball to the full open position.

Inlet flange ball valve closing process:

1 turn the handwheel clockwise when the valve is closed, the stem begins to fall and the ball begins to rotate.

2 continue to rotate the hand wheel, the valve stem is embedded in the spiral groove on the role of the guide pin, the stem and the ball at the same time rotate 90 degrees.

3 close, the ball has no contact with the valve seat in the case of rotation of 90 degrees.

4 hand wheel rotation of the last few laps, the bottom of the valve stem to the angle of the plane mechanical wedge to the pressure of the ball, so that it is tightly pressed on the seat, to achieve full sealing.

進(jìn)口法蘭球閥產(chǎn)品特點(diǎn)：

1、適應(yīng)惡劣工作環(huán)境
球閥只需要用旋轉(zhuǎn)90度的操作和很小的轉(zhuǎn)動(dòng)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(lái)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、*、甲烷和乙烯等。球閥閥體可以是整體的，也可以是組合式的。

2、適用要求嚴(yán)格切斷工況
軌道球閥是一種比較新型的球閥類別，它有著自身結(jié)構(gòu)所*的一些*性，如開關(guān)無(wú)摩擦，密封不易磨損，啟閉力矩小。這樣可減小所配執(zhí)行器的規(guī)格。配以多回轉(zhuǎn)電動(dòng)執(zhí)行機(jī)構(gòu)，可實(shí)現(xiàn)對(duì)介質(zhì)的調(diào)節(jié)和嚴(yán)密切斷。

法蘭球閥產(chǎn)品之所以被廣泛使用，是因?yàn)樗哂泻芏鄡?yōu)點(diǎn)。而且隨著社會(huì)的不斷進(jìn)步，產(chǎn)品在各方面得到質(zhì)的飛躍。

Inlet flange ball valve product features:

1, to adapt to the harsh working environment

Only need to rotate the ball 90 degrees of operation and a small rotation torque can be closed tight. Full equality of the valve body cavity provides a small resistance, through the flow channel. It is generally believed that the most suitable for the use of open and close valve, but the recent development has been designed to make it a throttle valve and control the flow of use. The main features of the valve itself is compact, easy operation and maintenance for water, solvents, acids, and natural gas general working media, but also applies to poor working conditions of media, such as oxygen, hydrogen peroxide, methane and ethylene. Ball valve body can be whole, it can be a combination of.

2, the requirements of strict cut-off conditions

Track ball valve is a new type of ball valve, it has its own unique advantages of the structure, such as the switch without friction, seal is not easy to wear, opening and closing torque is small. This reduces the size of the actuator. Equipped with multi turn electric actuator, which can adjust the medium and cut off tightly.

Flange ball valve products are widely used, because it has many advantages. And with the continuous progress of the society, the product has been a qualitative leap in all aspects.
