产品描述

高性能直通切断球阀    High-performance full bore shutoff ball valve

DC5621   浮动式软密封球阀

DC5622   浮动式金属硬密封球阀

DC5623   固定式软密封球阀

DC5624   固定式金属硬密封球阀

    该系列金属密封球阀适用于高温,高压等各种场合,并能达到阀座的零泄漏。利用HVOF设备,向球体与阀座表面喷涂硬度极高的碳化钨或碳化铬合金,具有高耐冲蚀性、高耐磨性、使用寿命长的特点,并利用东辰独特的研磨技术,使阀座和球阀完全密封。由于弹簧的作用,阀座始终与球体面接触,利用其自清洗的功能防止异物进入密封面。该系列球阀虽然结构简单,最适用于浆料、粉尘等苛刻条件的场合。填料部位采用动负载的结构,可以有效防止填料的泄漏。

 
 

    This series of metal sealed ball valve is suitable for high temperature, high pressure and other occasions, and can achieve zero leakage of the valve seat. HVOF equipment is used to spray the surface of the ball and valve seat with extremely hard tungsten carbide or chromium carbide alloy, which has the characteristics of high erosion resistance, high wear resistance and long service life. Using Dongchen's unique grinding technology, The seat and ball valve are completely sealed. Due to the action of the spring, the valve seat is always in contact with the ball surface, and the self-cleaning function is used to prevent foreign matter from entering the sealing surface. Although this series of ball valve has a simple structure, it is most suitable for the harsh conditions such as slurry and dust. The packing part adopts the structure of dynamic load, which can effectively prevent the leakage of the packing.

硬密封球阀

软密封球阀

 

采用特殊填料结构,能够满足泄漏等级低于100ppm的场合,同时又能对阀杆减少约20%的摩擦力。

The special packing structure can meet the leakage level below 100ppm, while reducing the friction of the valve stem by about 20%.

 

1、采用阀杆防飞出结构,可确保阀杆不飞出造成意外伤害。

The valve stem anti-flyout structure can ensure that the valve stem

 does not fly out and cause accidental injury.

 

2、阀座采用波形弹簧或圆柱弹簧及双刮刀结构,可以清洁球面,确保密封。

The valve seat adopts wave spring or cylindrical spring and double

scraper structure, which can clean the spherical surface and ensure the seal.

 

3、采用双密封结构,可确保介质不与弹簧接触,保证阀门密封。

The double seal structure can ensure that the medium does not contact

the spring and ensure the valve is sealed.

 

4、软密封阀座密封性能更稳定可靠。

Soft-sealed valve seat sealing performance is more stable and reliable.

 

5、设计排污吹扫结构可清洁阀门,防止阀门卡死。

The blowdown structure is designed to clean the valve and prevent

 the valve from being stuck.

 

6、符合API607标准的要求,具有防火、防静电功能。

It meets the requirements of API607 standard and has the functions

of fire prevention and antistatic.
