進口電動截止閥

德國巴赫進口電動截止閥概述：

 進口電動截止閥是由截止閥和多回轉(zhuǎn)電動執(zhí)行器等電氣控制元件組成的自控閥門系統(tǒng)，通常用在需要頻繁開閉需要實現(xiàn)大規(guī)模集中控制的場合。工作時，接入220VAC或380V電源即可控制運轉(zhuǎn)，也可加入控制模塊，輸入控制信號（4-20mADC或1-5VDC）進行調(diào)節(jié)控制，還可以加裝手輪，在必要時進行人為手動控制。根據(jù)不同的工藝要求選配不同的電動執(zhí)行器：如開關(guān)型、信號反饋型、防爆型、調(diào)節(jié)型等。

Imported electric globe valve

Overview of electric valve imported from Germany Bach:

Imports of electric valve is composed of valve control valve system and multi turn electric actuator and other electrical control components, usually used in the frequent large-scale centralized control occasions closed. When working, access 220VAC or 380V power to control operation, it can be added to the control module, the input control signal (4-20mADC or 1-5VDC) for regulation and control, can be equipped with a hand wheel, for manual control when necessary. According to the different requirements of the process of the selection of different types of electric actuators: such as switching, signal feedback, explosion-proof, adjustable type, etc..

 進口電動截止閥的啟閉件是塞形的閥瓣，密封面呈平面或錐面，閥瓣沿流體的中心線作直線運動。閥桿的運動形式，有升降桿式（閥桿升降，手輪不升降），也有升降旋轉(zhuǎn)桿式（手輪與閥桿一起旋轉(zhuǎn)升降，螺母設(shè)在閥體上）。截止閥只適用于全開和全關(guān)，不允許作調(diào)節(jié)和節(jié)流。 

Imported electric valve opening and closing parts are plug shaped valve, sealing surface flat or cone, fluid along the centerline of the valve for linear motion. The movement of the stem form, there are lifting rod (stem lift, hand wheel is not up and down), but also with the rotation of the rotary rod (hand wheel and stem together with the rotation of the nut in the valve body). Valve is only applicable to fully open and fully closed, does not allow for adjustment and throttle.

進口電動截止閥的定義：   

1、選材考究，符合國內(nèi)、外相關(guān)標準，結(jié)構(gòu)合理，造型美觀。
2、閥瓣、閥座密封面采用鐵基合金堆焊或司太立（Slite）鈷基硬質(zhì)合金堆焊而成，耐磨、耐高溫、耐腐蝕、抗擦傷性能好，使用壽命長。
4、閥桿經(jīng)調(diào)質(zhì)及表面氮化處理，有良好的抗腐蝕性和抗擦傷性。
5、可采用各種配管法蘭標準及法蘭密封面型式，滿足各種工程需要及用戶要求。
6、閥體材料品種齊全，填料、墊片可根據(jù)實際工況或用戶要求合理選配，能適用于各種壓力、溫度及介質(zhì)工況。
7、倒密封采用螺紋連接密封座或本體堆焊奧氏體不銹鋼而成，密封可靠，更換填料可在不停機情況下進行，方便快捷，不影響系統(tǒng)運行。
8、配有DZW系列多回轉(zhuǎn)式電動裝置，具有殼體小，重量輕，功能全，并可與遠程電腦配套使用，也可按用戶要求選配電動裝置。

The definition of imported electric valve:

1, material selection, in line with domestic and foreign standards, reasonable structure, beautiful appearance.

2, the valve flap and the valve seat sealing surface by the iron-based alloy surfacing or Slite (Slite) surfacing cobalt based alloy, wear resistance, high temperature resistance, corrosion resistance, good anti abrasion performance, long service life.

4, the stem through the quenching and tempering and surface nitriding treatment, good corrosion resistance and scratch resistance.

5, can be used with standard pipe flanges and flange sealing surface, to meet the needs of various projects and user requirements.

6, the valve body material is complete, packing, gasket can be based on actual conditions or user requirements reasonable matching, can be applied to all kinds of pressure, temperature and medium conditions.

7, the reverse seal with screw connection sealing seat or body welding austenitic stainless steel, reliable sealing, replacement of the packing can be in the case of non-stop, convenient, does not affect the operation of the system.

8, equipped with DZW series rotary electric device, has a small, light weight, full function, and can be matched with the remote computer, the user can also be equipped with electric device.
