四、分類/ Classification
根據(jù)不同工況，旋筒閥選用不同的控制元件，可以分類如下：
According to different working conditions, rotary cylinder valve selection of different control components, can be classified as follows:
A、全通型:主要用于切斷要求的場合。在管道系統(tǒng)中起對介質(zhì)的接通或截流，流通能力強(qiáng)，壓損小，雙向密封可達(dá)到零泄漏。
All pass: mainly used for cutting applications. In the pipe system, the medium is connected or cut, the flow capacity is strong, the pressure loss is small, the two-way sealing can achieve zero leakage.
B、調(diào)節(jié)型：主要用于調(diào)節(jié)要求的場合（大可調(diào)比）。在管道系統(tǒng)中主要起調(diào)節(jié)作用，閥門執(zhí)行機(jī)構(gòu)接收到控制信號。帶動閥筒作旋轉(zhuǎn)運(yùn)動，轉(zhuǎn)動作角度與控制信號成線性關(guān)系，從而控制管道中工藝參數(shù)的目的。流道口可按需要定制成線性、等百分比或一些特殊形狀從而獲得不同性能的流量曲線。
Adjustable type: mainly used to adjust the requirements of the occasion (adjustable ratio). In the pipe system, the main function of the valve actuator to receive control signal. Drive valve cylinder for rotary motion, rotation angle and control signal linear relationship, so as to control the process parameters in the pipeline. The flow rate can be customized according to the need to be linear, equal percentage or some special shape to obtain different performance of the flow curve.
C、 三通或多通（調(diào)節(jié)）型：L型、T型。三通型旋筒閥是指閥體有三個進(jìn)出口，三通旋筒閥分為L型和T型兩種,L型主要用于介質(zhì)的換向，介質(zhì)的流向從一根管道換為另一根管道。T型主要用于介質(zhì)的分流和合流，分流是控制一種介質(zhì)分別從不同的管道流出，合流是控制兩種介質(zhì)匯合于一根管道。
多通型旋筒閥是指垂直于執(zhí)行器的旋轉(zhuǎn)軸平面上有四個或以上進(jìn)出口，或在該平面的下端也有一個出口，該閥的作用主要用于兩種以上介質(zhì)的換向或匯合于一根管道。
Three way or multi pass (regulation) type: L type, T type. Three way type of rotary valve is the valve body has three import and export, the three valve is divided into L type and T type two, L type is mainly used for the medium of the direction of the flow from one pipe to another. T type is mainly used for the medium flow and confluence, the diversion is to control the flow of a medium separately from the different pipe, the confluence is the control of the two media convergence in a pipeline.
Multi type rotary cylinder valve refers to the vertical axis of the actuator on the axis of the plane has four or more of the import and export, or in the lower end of the plane also have an outlet, the role of the valve is mainly used for more than two medium or a pipe.
D、 降噪型：能有效降低噪聲。介質(zhì)在管道中流通，一定的條件下會產(chǎn)生大的噪聲，會對設(shè)備產(chǎn)生損壞，對環(huán)境造成污染。因此在閥內(nèi)件設(shè)計(jì)采取一些降噪措施可降低噪聲。
Noise reduction type: can effectively reduce the noise. Medium in the pipe flow, certain conditions will produce large noise, will cause damage to the equipment, environmental pollution. Therefore in the valve design to take some noise reduction measures can reduce the noise
E、小流量型：當(dāng)介質(zhì)的流量很微小時(shí)，閥門很小的開度就達(dá)到了流量要求，因此無法正常調(diào)節(jié)，此時(shí)可將節(jié)流口形狀設(shè)計(jì)為最小1mm寬的矩型窗口，流量特性為線性，Cv值可達(dá)到極小，從而提高了微小流量時(shí)的控制精度。
Small flow type: when the medium flow is very small, the valve is very small opening to meet the flow requirements, and therefore can not be adjusted, this time can be the throttle orifice shape design for the minimum 1mm wide window, flow characteristics for linear, Cv value can reach a minimum, so as to improve the control accuracy of micro flow.
F、反汽蝕型：汽蝕是材料在液體的壓力和溫度達(dá)到臨界值時(shí)產(chǎn)生的一種破壞形式，汽蝕分為閃蒸和空化兩個階段。管道中的液體在一定的條件下，部分液體氣化成氣體狀態(tài)，產(chǎn)生氣泡，形成氣液兩相流這就是閃蒸過程。閥下游的壓力升高，壓破氣泡的過程即空化過程。汽蝕可使閥內(nèi)件的表面產(chǎn)生磨痕、深溝及凹坑。閥一般采用曲折路徑、多級降壓、多孔節(jié)流及引導(dǎo)介質(zhì)流向閥體中心區(qū)防止沖擊閥體內(nèi)壁的方式來防止和降低汽蝕的破壞。
The anti cavitation, cavitation is material in the pressure and temperature of the liquid reaches critical values produced a failure mode, cavitation is divided into two stages, such as flashing and cavitation. The liquid in the pipeline under certain conditions and partially vaporizes into gas state, bubble, formation of gas-liquid two-phase flow which is the process of flash. Downstream of the valve's pressure increases, the cavitation bubble crush process process. Cavitation can make the surface trim have worn, and deep pits. Valve is generally used in a tortuous path, multi-stage pressure, porous throttle and guide the flow of the valve body center to prevent the impact of the inner wall of the valve body to prevent and reduce the damage of cavitation.
G、多級降壓降噪型：當(dāng)介質(zhì)在管道中流過后噪聲級別相當(dāng)高時(shí)，也可通過多級降壓降噪的方式來解決。

角式旋筒閥的閥芯與閥座的材料經(jīng)過精加工而制成，表面粗糙度達(dá)到Rc0.04，材料硬度達(dá)到HRA90以上極耐磨。傳統(tǒng)的黑水調(diào)節(jié)閥采用文丘里角式直行程結(jié)構(gòu)，流向?yàn)楦哌M(jìn)低出，啟閉力量大，閥桿上下動作，因閥桿與導(dǎo)向套之間有間隙，容易產(chǎn)生振蕩出象，經(jīng)常閥芯從根部折斷，用了一段時(shí)間后，閥桿上容易結(jié)垢，致使閥芯無法動作。而角式旋筒閥為角行程動作，旋轉(zhuǎn)扭矩小，在轉(zhuǎn)動過程中具有自潔功能，筒式閥芯與閥體之間接觸面積大而均勻，解決了傳統(tǒng)角式座閥的振動與爬行現(xiàn)象，閥芯與閥座之間鏡面接觸，保證了密封的可靠性，從而提高了調(diào)節(jié)精度。
Mainly used for high pressure or flow resistance of the working conditions, but also can be used as the bottom discharge valve. The pressure and flow is particularly suitable for the coal chemical industry in the black and gray water regulation.
The valve core and valve seat of the valve core and valve seat material after finishing, the surface roughness reached Rc0.04, the material hardness of the HRA90 more than a very abrasive. Traditional black water regulating valve adopts venturi angle type straight stroke structure, the flow of high into a low, opening and closing force, stem moves up and down, there is a gap between the stem and the guide sleeve, prone to oscillate like, often the spool from the roots broken, a period of time, the stem is easy to scale, resulting in the spool can not action. The angle rotary cylinder valve for angular stroke, rotary torque is small, in the process of rotation with the self clean function, cylinder type valve body with large contact area between large and uniform, to solve the traditional angle seat valve vibration and crawling phenomenon, the valve core and valve seat contact between the valve and the valve to ensure the reliability of the sealing, thereby improving the accuracy of adjustment.
