丹富斯焊接球閥性能：保溫焊接球閥/丹富斯保溫球閥

1）：不需要維護(hù)，調(diào)整及潤滑，易于安裝，在低運行費用下*可靠運行。表面采用噴塑處理技術(shù)，光澤美觀，在國內(nèi)已處于水平。不會有外部泄漏等現(xiàn)象。閥體是焊接結(jié)構(gòu)，所以閥門重量輕且易于進(jìn)行絕緣。安裝調(diào)節(jié)機(jī)構(gòu)，非常簡便，操作手柄可以拆下，換向安裝。

2）：由于閥座是由碳纖維增強(qiáng)特氟隆密封環(huán)及碟形簧構(gòu)成的，所以對壓力和溫度的變化適應(yīng)能力強(qiáng)，在標(biāo)注壓力和溫度范圍內(nèi)不會產(chǎn)生任何泄滑。

3）：球體的加工過程有*的計算機(jī)檢測儀跟蹤檢測，所以球體的加工精度高。

4）：由于閥體材料跟管道材質(zhì)一樣，不會出現(xiàn)應(yīng)力不均，也不會由于地震及車輛經(jīng)過地面時而產(chǎn)生變形，管道耐老化。保溫焊接球閥/丹富斯保溫球閥

5）：整體式全焊接，等徑及變徑通道，采用固定球及浮動球，雙活塞效應(yīng)密封系統(tǒng)，自動

注入密封劑式軸承。

6）：為了防止靜電，閥桿與球體以及閥桿與填料箱之間分別裝有鋼球和彈簧，可以保持閥門所有零件與閥體的導(dǎo)電，讓電流通過區(qū)，釋放靜電。不僅防止火災(zāi)，而且防止腐蝕，實現(xiàn)臨時性切斷，以便及時檢修。

7）：閥桿防脫功能是因為閥桿受閥內(nèi)壓力影響，總產(chǎn)生脫離的力所以閥桿設(shè)計成防脫結(jié)構(gòu)。

8）：用低摩擦材料的止推墊圈支撐將壓力推向閥桿，使閥桿僅僅起到傳遞扭矩的作用。

Dan fuss full welded ball valve material:

1) : body: carbon steel ST37.0, A106 - B; 20 # steel

2) : sphere: stainless steel 304 or 304

3) : stem: 2 cr13

4) : stem seal: perfluorinated like glue

(5) : ball seal: RTFE PTFE + C)

Dan fuss welded ball valve performance:

1) : I don't need to maintain, adjust and lubrication, easy to install, low in operating cost under long-term reliable operation. Surface using pensu processing, gloss and beautiful, has been in a leading level in China. There won't be the phenomenon such as external leakage. The body is welded structure, so the valve light weight and easy for insulation. Install regulator, it is very simple, the operation handle can be removed, reversing the installation.

2) : because the seat is made of carbon fibre reinforced teflon seal ring and disc spring, so the ability to adapt to the change of pressure and temperature, the annotation of pressure and temperature range will not produce any drainage and smooth.

3) : the sphere have advanced computer processing detector tracking detection, so the sphere of high machining accuracy.

4) : as the body material as pipe material, won't appear uneven stress, also won't because of the earthquake and the vehicle through the ground deformation, occurs when pipe ageing resistance.

5) : integral whole welding, such as diameter and variable diameter channel, the fixed and floating ball, double piston effect sealing system, automatically

Injecting sealant bearing.

6) : in order to prevent electrostatic, stem and sphere and valve stem and packing box with a ball and spring respectively, between conductive can keep all parts of valve and valve body, let electricity pass through are area, release of static electricity. Not only prevent fire, and to prevent corrosion, the realization of a temporary cut, in order to timely maintenance.

7) : stem resistance function is because a pressure in the valve stem, always so the force generated from stem designed to prevent to take off the structure.

8) : the thrust washer with low friction material support will be pressure to the valve stem, the stem just have the effect of torque.
