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.
