Introduction

  The opening and closing component of Z41H cast steel flange gate valve is the gate, and the movement direction of the gate is perpendicular to the fluid direction. The gate valve can only be fully opened and fully closed, and cannot be adjusted or throttled. When the gate valve is closed, the sealing surface can be sealed solely by the pressure of the medium, that is, the sealing surface of the gate is pressed against the valve seat on the other side by the pressure of the medium to ensure the sealing of the sealing surface.
Z41H鑄鋼法蘭閘閥的啟閉件是閘板,閘板的運動方向與流體方向相垂直,閘閥只能作全開和全關(guān),不能做調(diào)節(jié)和節(jié)流。閘閥關(guān)閉時,密封面可以只依靠介質(zhì)壓力來密封,即只依靠介質(zhì)壓力將閘板的密封面壓向另一側(cè)的閥座來保證密封面的密封。

Z41H cast steel gate valve is suitable for cutting off or connecting pipeline media in various systems of petroleum, chemical, hydraulic, and thermal power plants with nominal pressure PN1.6~16.0MPa and working temperature ≤ -29 ℃~550 ℃. Manual flange gate valves are suitable for media such as water, oil, steam, acid, alkali, ammonia, urea, and sulfur-containing natural gas. The operation modes include manual, gear transmission, electric, pneumatic, etc.
Z41H鑄鋼閘閥適用于公稱壓力PN1.6~16.0MPa,工作溫度≤-29℃~550℃的石油、化工、水力、火力電站多種系統(tǒng)的管路上,切斷或接通管路介質(zhì)。手動法蘭閘閥適用介質(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。

Z41H cast steel flange gate valve features:
1. Compliant with domestic and international standards, reliable sealing, excellent performance, and beautiful appearance;
2. The sealing surface of the gate and valve seat is welded with cobalt based alloy or Stellite cobalt based alloy, which has good wear resistance, high temperature resistance, corrosion resistance, abrasion resistance, and long service life;
3. Adopting a wedge-shaped elastic gate structure, with rolling bearings installed on medium and large diameters, the switch is flexible and easy to open and close;
4. The valve body material variety is complete, and the packing and gasket can be reasonably selected according to actual working conditions or customer requirements, which can be suitable for various pressure, temperature, and medium working conditions.
Z41H鑄鋼法蘭閘閥節(jié)閥特點
1、符合國內(nèi)外標準,密封可靠,性能優(yōu)良,造型美觀;
2、閘板、閥座密封面用鈷基合金堆焊或司太立鈷基合金堆焊而成,耐磨、耐高溫、耐腐蝕、抗擦傷性能好、使用壽命長;
3、采用楔式彈性閘板結(jié)構(gòu),中大口徑設(shè)置滾動軸承,開關(guān)靈活,啟閉輕松;
4、閥體材料品種齊全,填料、墊片可根據(jù)實際工況或客戶要求合理選配,能適用于各種壓力、溫度及介質(zhì)工況。
