进口全封闭波纹管闸阀Product description:

Including valve body, gate, valve stem, bonnet, nut and handwheel, spiral wound gasket is designed between the lower end of bonnet and the upper end of valve body, which is connected and fixed by bolts and nuts; The upper end of the valve cover is designed with a bracket, and spiral wound gaskets are designed between the bracket and the upper end of the valve cover, which are connected and fixed by bolts and nuts; The hand wheel is designed on the upper end of the support, the valve stem is connected with the gate plate designed in the valve body through the support and bonnet in turn, the upper end of the valve stem is connected with the hand wheel, the valve stem is designed with a bellows, the bellows is sheathed with a guide sleeve, the valve stem is composed of the upper valve stem and the lower valve stem, the upper valve stem and the lower valve stem are connected by an embedded threaded connection structure, the valve nut is embedded in the upper valve stem, and is connected and fixed by a set screw; The lower part of the support is designed with packing, the upper part of the packing is designed with packing gland and packing pressing plate, and the lower part of the support is designed with bearing structure. The products designed with this structure can make up for the shortcomings of the existing technology.

进口全封闭波纹管闸阀characteristic:

Bellows stop valves and bellows gate valves. In the case of large diameter, it is obviously not suitable because the large thrust and torque of the large diameter bellows stop valve make it difficult to open and close; If the bellows gate valve is selected, although the thrust of the bellows gate valve is small and the torque is light, the height of the large diameter bellows gate valve is very high, which requires a lot of installation and operation space. Obviously, the conventional bellows gate valve structure is not very suitable. Therefore, our company has developed a bellows gate valve for this working condition, which can solve the problem of difficult opening and closing, as well as the problem of large installation and operation space.

进口全封闭波纹管闸阀Principle:

Fully enclosed bellow gate valve, including valve body, gate, valve stem, bonnet, nut and handwheel. Spiral wound gasket is designed between the lower end of bonnet and the upper end of valve body, which is connected and fixed by bolts and nuts; The upper end of the valve cover is designed with a bracket, and spiral wound gaskets are designed between the bracket and the valve cover, which are connected and fixed by bolts and nuts; The hand wheel is designed at the upper end of the support, the valve stem is connected with the gate plate designed in the valve body through the support bonnet in turn, the upper end of the valve stem is connected with the hand wheel, the valve stem is designed with a corrugated pipe, the corrugated pipe sleeve is equipped with a guide sleeve, the valve stem is composed of the upper valve stem and the lower valve stem, the upper valve stem and the lower valve stem are connected by an embedded threaded connection structure, the valve nut is embedded in the upper valve stem, and is connected and fixed by a set screw; The lower part of the support is designed with packing, the upper part of the packing is designed with packing gland and packing pressing plate, and the upper part of the support is designed with bearing structure, which is connected and fixed on the support through set screws. The bearing structure is composed of shaft sleeve, thrust ball bearing and bearing gland. The thrust ball bearing is designed in the shaft sleeve, and the bearing gland is designed above the thrust ball bearing.
