進(jìn)口鑄鋼法蘭閘閥

 

德國巴赫進(jìn)口鑄鋼法蘭閘閥概述：Ioduction of Bach cast steel flanged gate valve imported from germany:

進(jìn)口鑄鋼法蘭閘閥又稱閘板閥或閘門閥，應(yīng)用較廣泛的一種閥門。它是通過閘板的升降來控制閥門的啟閉，閘板垂直于流體方向，改變閘板與閥座間相對位置即可改變通道大小。適用于公稱壓力PN1.6～16.0MPa,工作溫度≤-29℃～550℃的石油、化工、水力、火力電站各種系統(tǒng)的管路上，切斷或接通管路介質(zhì)。

Imports the valve lock valve or gate valve, a valve is the most widely used. It cools the opening and closing of the valve through the lifting of the gate. The gate is perpendicular to the direction of the fluid and changes the relative position between the gate and the valve seat to change the channel size. For nominal pressure PN1.6 ~ 16.0MPa, -29 pipeline wong temperature less than 550 DEG C, hydraulic oil and chemical industry, thermal power plants of various systems, cut off or connected piping media.適用介質(zhì)為：水、油品、蒸氣、及酸、堿、氨、尿素、含硫天然氣等。操作方式有：手動、齒輪傳動、電動、氣動等。

 

進(jìn)口鑄鋼法蘭閘閥的定義：Definition of imported cast steel flanged gate valve:   

1、選材考究，符合國內(nèi)外相關(guān)標(biāo)準(zhǔn)，材料的一體質(zhì)量高。
2、符合國內(nèi)外先進(jìn)標(biāo)準(zhǔn)的要求，密封可靠、性能優(yōu)良、造型美觀。
3、閥桿經(jīng)調(diào)質(zhì)及表面氮化處理，有良好的抗腐蝕性、抗擦傷性和耐磨性。
4、可采用各種配管法蘭標(biāo)準(zhǔn)及法蘭密封面形式，滿足各種工程需要及用戶要求。
5、采用楔式彈性閘板結(jié)構(gòu)，中大口徑設(shè)置推力軸承，磨擦力小，并配有撞擊手輪，啟閉輕松自如。
6、密封副配對先進(jìn)合理，閘板和閥座的密封面采用不同硬度的司太立（Stellite）鈷基硬質(zhì)合金堆焊而成，密封可靠、硬度高、耐磨、耐高溫、耐腐蝕、抗擦傷性能好、壽命長。

1, material selection, in line with relevant standards at home and abroad, the overall quality of the material is high.

2、2, meet the requirements of advanced standards at home and abroad, reliable sealing, good performance, beautiful appearance.

3、3. The valve stem is quenched and tempered and treated by surface nitriding. It has good corrosion resistance, scratch resistance and wear resistance.

4、4, can use a variety of piping flange standards and flange sealing surface form, to meet the needs of various engineering and user requirements.

5、5, wedge type elastic ram structure, large and medium caliber thrust bearing, small friction force, and with impact handwheel, easy to open and close.

6、6, sealing pairs of advanced and reasonable, gate and valve seat sealing surface with different hardness of Si Taili (Stellite) cobalt based carbide surfacing, sealing reliable, high hardness, wear resistance, high temperature resistance, corrosion resistance, good scratch resistance, long life.
