Abstract
The utility model is related to a kind of breathing valve inserts, including mounting ring and circular unlatching tongue, integrally make a linkage section in periphery mounting ring inner edge interval, integrally make circular unlatching tongue in linkage section end, circle opens tongue and installation central spacer coaxial arrangement, and uniformly distributed four mounting holes, are embedded in tissue layer in linkage section in mounting ring, tissue layer is co-axially mounted metal reinforcing ring to mounting ring and circular unlatching tongue both sides extended segment in the outer rim of mounting ring interior installing hole.Breathing valve insert provided by the utility model is opening embedded one layer of tissue layer in tongue, can increase the wearability opened repeatedly of rubber, and flexibility when not influencing also to open ensure that leakproofness.
Description
Technical field
The utility model belongs to field of sealing technology, particularly a kind of breathing valve insert.
Background technology
Breather valve is to safeguard that cartridge gas pressure balances, and reduces the energy-saving safe product of medium volatilization, breather valve makes full use of storage
The bearing capacity of tank in itself reduces media discharge, and principle is to control the exhaust of storage tank just using the weight of positive/negative-pressure valve disc
Pressure and intake negative-pressure；When extracting medium out outside toward tank, decline the pressure of the tank internal upper part gas compartment, the operation for reaching breather valve is born
During pressure, the air outside tank is open-top by the negative pressure valve disc of open-top breather valve, and ambient atmos is made to enter in tank, makes pressure in tank no longer
Continue to decline, allow in tank with the air pressure balance outside tank, to protect the safety device of storage tank.
The gasket of breather valve is there are one tongue, through normally open, be easy to cause fracture.
Utility model content
The purpose of the utility model is to overcome in place of the deficiencies in the prior art, providing, a kind of opening times are more, are not afraid of mill
The breathing valve insert of damage.
Technical solution is used by the utility model solves its technical problem：
A kind of breathing valve insert, including mounting ring and circular unlatching tongue, periphery mounting ring inner edge interval integrally makes one
Circular unlatching tongue is integrally made in linkage section, linkage section end, and circle is opened tongue and is coaxially disposed with installation central spacer, in mounting ring
Uniformly distributed four mounting holes, it is characterised in that：Tissue layer is embedded in linkage section, tissue layer opens tongue two to mounting ring and circle
Side extended segment.
Metal reinforcing ring is co-axially mounted in the outer rim of mounting ring interior installing hole.
The advantages of the utility model and good effect are：
Breathing valve insert provided by the utility model is opening embedded one layer of tissue layer in tongue, can increase the anti-of rubber
The wearability opened again, flexibility when not influencing also to open, ensure that leakproofness.
Breathing valve insert provided by the utility model embeds a metal reinforcing ring, metal reinforcing ring energy in mounting hole circumference
It is enough to alleviate extruding of the bolt to gasket when installing, also it can ensure leakproofness simultaneously.
Description of the drawings
Fig. 1 is the dimensional structure diagram of the utility model.
Fig. 2 is sectional view along A-A in Fig. 1.
Specific embodiment
Below in conjunction with the accompanying drawings and pass through specific embodiment the utility model is described in further detail, following embodiment is simply retouched
The property stated, be not limited, it is impossible to limit the scope of protection of the utility model with this.
A kind of breathing valve insert, including mounting ring 1 and circular unlatching tongue 3, periphery mounting ring inner edge interval is integrally made
Circular unlatching tongue is integrally made in one linkage section 4, linkage section end, and circle is opened tongue and is coaxially disposed with installation central spacer, installed
Uniformly distributed four mounting holes 2 on ring.
The innovation of the utility model is：
1st, tissue layer 6 is embedded in linkage section, for tissue layer to mounting ring and circular unlatching tongue both sides extended segment, material can
To be aramid fiber, glass fibre etc., for increasing folding times.
2nd, metal reinforcing ring 5 is co-axially mounted in the outer rim of mounting ring interior installing hole, when metal reinforcing ring can alleviate installation
Extruding of the bolt to gasket can also ensure leakproofness simultaneously.
Claims (2)
1. a kind of breathing valve insert, including mounting ring and circular unlatching tongue, a company is integrally made at periphery mounting ring inner edge interval
