Description
Technical field
The present invention relates to technical field of sealing technology, particularly a kind of sealing device with O-ring.
Background technology
The function one of sealing is to prevent liquid inside machine or gas from being let out between the faying face of two parts, two
It is impurity, the dust intrusion for preventing outside, keeps the necessary environment of machine components normal work.
The parts and components to seal are referred to as seal or sealing device, referred to as seal.The quality of sealing, direct relation
To the work quality and service life of a machine, can't adopt a casual attitude.Some occasions, the degree of reliability of sealing are particularly heavy
Will, such as aircraft and spaceborne sealing, poison gas, venom storage tank, the sealing of inflammable, explosion hazard gases storage tank etc..
Most seals have standardized, seriation, are selected according to condition of work and requirement.
Existing sealing device is all that substance seals, and heat resistance, chemical resistance of some particular surroundings to sealing device,
Particularly friction, wear hardness propose very high request.
The content of the invention
Based on this, in view of the above-mentioned problems, be necessary to propose a kind of sealing device with O-ring, the sealing device it is close
Envelope seat is made of PTFE or modified ptfe or UPE or PP materials, and O-ring seal uses rubber or fluorine glue or silica gel or polyurethane
Material is made, and the sealing device has good heat resistance, chemical resistance, and particularly friction, wear hardness are good.
The technical scheme is that：A kind of sealing device with O-ring, including seal receptacle and the first O-ring seal,
Described seal receptacle is annular, and the top of the seal receptacle is provided with the first O-ring seal mounting groove, the described first O-shaped sealing
Circle is installed in the first described O-ring seal mounting groove, and the top of the first O-ring seal mounting groove is provided with inwardly convex
Rise, described projection is used to after installing the first described O-ring seal in the first described O-ring seal mounting groove be blocked
Firmly fix, described seal receptacle is made of PTFE or modified ptfe or UPE or PP materials, and the first described O-ring seal is adopted
It is made of rubber or fluorine glue or silica gel or polyurethane material.
Temperature can be used to be no more than 100 degree for common product, after using modified ptfe, temperature in use can be optimized into zero
Lower 100 degree to 300 degrees Celsius, the formula of modified ptfe has many kinds, and addible additive also has many kinds, such as adds 10%-
15% carbon is fine, can select the modified ptfe of different formulations as needed.
Preferably, the gusset of the seal receptacle is provided with the second O-ring seal mounting groove, the second described O-ring seal peace
Second O-ring seal is installed in tankage.
Pass through the dual close of the first O-ring seal at the top of seal receptacle and the second O-ring seal of seal receptacle gusset
Envelope, reaches better seal effect.
Preferably, the second described O-ring seal is made of rubber or fluorine glue or silica gel or polyurethane material.
It is further preferred, modified ptfe can be added in described the first O-ring seal and the second O-ring seal, to carry
High its processing characteristics and performance, as heat resistance, chemical resistance, particularly friction, wear hardness can increase substantially.
The beneficial effects of the invention are as follows：
（1）When seal receptacle is made of modified ptfe material, different additives can be added in PTFE as needed, improves it
Performance, different use conditions can be met；
（2）Seal receptacle periphery sets the effect of formation dual-seal after the second O-ring seal so that sealing effectiveness is more preferable.
