How to check the sealing of the two-position two-way solenoid valve?

Two-position two-way solenoid valve sealant application FAQ In order to better ensure the role of sealing, the selection of sealant must take into account a good number of the following key characteristics.

1. Excellent inlay, squeeze, storage reliability, non-toxic or slightly toxic, and other news media low infiltration;

2. Can resist expansion and contraction of fitness movements, deflections and deformations of joints;

3. In suffering from circulatory system deformation bone and joint, can ensure through gas with two-position two-way solenoid valve function and look like a complete recovery;

4. Have enough ability to withstand the force;

5. Do not peel, synergistic industrial base open glue adhesive reliability;

6. Do not in high temperature, ultra-low temperature does not scorch crack too much softening;

7. Aging resistance, not delamination, cracking, scattering or too much collection, sliding two-position two-way solenoid valve has enough daily life;

8. special places, such as when there is a major performance wear resistance, puncture resistance, corrosion resistance, rolling resistance, flammability, pneumatic solenoid valve does not environmental pollution, insulation or conductivity, etc.

Recently, some customers have asked us about the difference between sealant and sealant grease, and we will briefly introduce the difference between them.

1. Sealant is generally divided into four types of forms

1) Mud sealant: generally used for low-grade sealant.

2) liquid elastomeric material sealant: with the ability to bear repeated seam deformation work, stainless steel two-position two-way solenoid valve use period is generally 15 ~ 20 years. This type of sealant has a high bonding and shear strength indoor temperature has excellent flexibility;.

3) hot melt sealant: also known as hot engineering construction type sealant.

4) liquid sealant: this type of sealant key used to mechanical equipment fusion surface sealing to replace the solid rubber seals paper strip. Stone wool. Cork board and rubber materials to avoid machinery and equipment internal liquid leakage from the fusion surface, so the liquid sealant is also known as the liquid seal ring.
