結(jié)構(gòu)說(shuō)明和工作原理 About the structure and working principle

(一)浮動(dòng)式球閥 Floating ball valve

1、閥門開(kāi)、關(guān)位置指示Indication of valve's open and close positions:       

球、閥桿、手柄是一個(gè)裝配單元,閥桿頭部采用扁方結(jié)構(gòu),由手柄所處位置容易辨別出閥門是處于開(kāi)位置或關(guān)位置。當(dāng)手柄或閥桿頭部的扁方與管線平行時(shí),閥門處于全開(kāi)位置;當(dāng)手柄或閥桿頭部的扁方與管線垂直時(shí),閥門處于全關(guān)位置。

Ball, stem and handle are one assembly unit. The stem head is a flat-square structure and the valve is easy to be seen either in the opened or closed position from the place the handle is in. When the handle or the flat-square of the stem head is parallel with the pipeline, the valve is in the fully opened position; while in the fully closed one when vertical to the pipeline.

2、鎖定裝置Locker:       

為防止誤操作閥門,在閥門的全開(kāi)和全關(guān)位置可用掛鎖鎖定閥門,特別是安裝在野外的閥門或當(dāng)工藝流程中不允許開(kāi)或關(guān)閥門時(shí),為防止其他人員錯(cuò)誤操作閥門,將閥門位置鎖定是很重要的。

To prevent maloperation of the valve, a hanging lock can be used to lock it when in the fully opened or closed position, which is very important especially for the valve mounted outside or not allowed to be opened or closed by the technological flow.

3、閥桿防飛結(jié)構(gòu)Stem fly-resisting structure:       

當(dāng)介質(zhì)通過(guò)閥門時(shí),閥體中腔的壓力可能將閥桿推出。為防止這種情況發(fā)生,在閥桿下部設(shè)置一防飛出結(jié)構(gòu)(圖1)。這樣,即使火災(zāi)時(shí),填料、止推軸承被燒損或其它原因引起填料等損壞,閥體內(nèi)的介質(zhì)壓力將使閥桿臺(tái)肩與閥體上密封面緊密接觸,防止介質(zhì)大量從損壞的填料部位處泄漏。

The stem may be pushed out by the pressure in the middle cavity of the body when the medium goes through the valve. To prevent this, a fly-resisting structure is made on the lower part of the stem (Fig. 1). In this way, even if the packing and/or thrust bearing are burnt out in a fire or damaged by other causes, the medium's pressure inside of the body will have both stem flange and upper sealing face of body tightly contacted so as to prevent a lot of medium from leaking from the damaged packing place.

4、防靜電裝置及防火結(jié)構(gòu)Electrostatic-proof device and fire-fighting structure:       

設(shè)計(jì)了防靜電裝置(圖2)和防火結(jié)構(gòu)(圖3)。當(dāng)發(fā)生火災(zāi)時(shí),一旦閥座被燒損,球體將直接和閥體上的金屬面接觸,從而阻止介質(zhì)大量從燒損的閥座處泄漏。

Both electrostatic-proof device (Fig. 2) and fire-fighting structure (Fig. 3) are designed. Once the seat ring is burnt out in case of a fire, the ball would be directly contacted with the metal face of the body so as to prevent a lot of medium from leaking from the burnt place of the seat ring.

6、全通徑或縮徑Full or reduced diameter:       

閥門公稱通徑與管線內(nèi)徑一致(客戶要求時(shí)可為縮徑),以便管線清掃(圖6)。

The valve nominal diameter is identical to the inner diameter of the pipeline (which can be reduced one if so required by users) for the sake of cleaning (Fig. 6).
