the bellows globe valve seal structure has a variety of design, its sealing principle and sealing force also each are not identical. Basic is divided into: plane seal and seal cone, spherical sealing seal with diameter. The plane sealing and

taper sealing in the corrugated pipe cut-off valve is widely used. Below respectively introduce the characteristics of different sealing surface: surface sealing seal was adopted in corrugated pipe cut-off Industrial Valves is the most common, the advantage is that interface is tight fit without friction, so to shut down a request is not high, at the same time, due to pipe stress and make the seal face round

degrees by deformation, also won't affect the sealing surface sealing performance. The opening requirement is also the most easy to achieve. The disadvantage is that the medium solids sediment and easy to damage the sealing surface.

made conical taper sealing cone sealing is to put the seal face, narrow the contact area. This seal under certain sealing force, the sealing pressure ratio increase greatly, easy to seal. On the premise of guarantee the seal, and plane

compared to seal, the sealing force imposed by the small. Due to the narrow sealing surface is not easy to make the disc correctly on seat, in order to achieve the best sealing performance, must guide on the disc. The disc to guide

, can achieve good sealing performance. Disc in the valve guide, disc by the body under the lateral flow medium thrust, rather than by the stem to withstand, this will further enhance the sealing

and the reliability of the packing seal. Taper sealing is under the condition of the friction, so sealing material must can scratch. Peace than face seal, the solid particle and sediment medium damage are relatively less a

some, but also should not be in the medium containing solid particles and sediment medium is used. In order to improve the strength of the conical seal and not sacrifice its sealing stress, 15 °, the seal face half cone Angle to make it provide

a wide sealing surface, can more easily and the valve seat Industrial Valves seal. Stress, in order to achieve higher sealing valve seat sealing surface began to come into contact with the disc part narrower, about 3 mm, the rest have a taper part can be a bit

longer. When sealing load increases, the degree of disc sliding seat, thus increasing the width of sealing face. This design of sealing face not as susceptible to erosion as narrow sealing surface damage. In addition, because the cone

profile is longer, the throttle valve features to improve.

the characteristics of the corrugated pipe cut-off valve, corrugated pipe cut-off valve 1 long service life, reduce the number of maintenance, lower operating costs. 2, strong and durable bellows seal design, guarantee the zero leakage of the stem, provide no maintenance conditions. 3, gas medium PTFE seat is soft sealing material to improve the valve's sealing;
