Two of the most useful properties of titanium are corrosion resistance and the highest strength-to-weight ratio of any metal. In its non-alloyed state, titanium is as strong as some steels, but 45% lighter. Titanium has similar chemical and physical properties to zirconium because both have the same number of valence electrons and belong to the same group of elements in the periodic table.
The valve seat is a detachable part inside the valve, which is used to support the valve core's full clearance and form a sealing pair. Generally, the valve seat diameter is the maximum flow diameter of the valve. For example, butterfly valve seat material is very extensive, all kinds of rubber, plastic, metal materials can be used as seat material.
The valve seat uses elastic sealing material and small actuating mechanism to obtain the bubble tight level seal. The compression seat sealing stress causes the material to be elastically deformed and squeezed into the rough surface of the metal parts to be used to block all the leakage paths. The permeability of the material is the basis for a small amount of leakage to the fluid.
If the material is too soft or cold deformation (creep) occurs under load, fillers such as glass fiber can be added to harden it. If used to make thin sheets, it can still meet the requirements of use, and can eliminate cold deformation or permanent deformation.
The seal must be carefully fixed to prevent rupture and air leakage due to differential pressure. The soft seat is bonded to the metal part, but it can not solve the problem completely. Because of the thermal shock, the bond will break and fail. Enough pressure drop will damage the bonding material.
Characteristic:
1) Good fluid compatibility, including expansion, hardness loss, permeability and degradation;
2) High hardness;
3) Permanent deformation;
4) The degree of recovery after load removal;
5) Pulping and compression strength;
6) Deformation before rupture;
7) Elastic modulus.
