Description
Technical field
The utility model belongs to air valve technical field, and in particular to a kind of air valve.
Background technology
Air valve is mainly by valve seat, valve block, spring, lift limiter and the bolt for being integrated their groups, the compositions such as nut.
The structure of air bleeding valve and inlet valve are essentially identical, and the two is only the location swap of valve seat and lift limiter, air-breathing lift of a valve limit
For device processed close to cylinder inboard, air bleeding valve is then valve seat close to cylinder inboard.Annular valve is gained the name valve seat because its valve block is thin annulus
And have on lift limiter annular or hole shape channel, it is for gas to pass through.Valve block is bonded to form sealing with the seal on valve seat.
There are guide ledges on lift limiter, play the guiding role to valve block lifting.Valve seat and lift limiter are hit load, valve seat
Also subject to the gas pressure difference of valve both sides.It is required that material impact-resistant and having sufficient intensity.The material of valve seat and lift limiter can
According to the difference of gas property and bears the difference of pressure difference and select corresponding material.Valve plate material should have intensity high, tough
Good, the wear-resisting, corrosion resistance of property.Spring for valve generally uses carbon spring steel, the materials such as alloy spring steel and stainless steel.Compression
Machine air valve is in addition to annular valve, also Valves, disc valve, ports valve and straight-wavy valve etc..Its action principle is substantially the same with annular valve,
But the characteristics of having nothing in common with each other.
Existing air valve when in use, due to being used cooperatively with reciprocating vacuum pump, will produce very high temperature, lead
It causes the service life of air valve to shorten, and dust can be accumulated in the venthole of air valve when in use, ventilation hole plug is made
The problem of ventilatory capacity of air valve declines, thus it is proposed that a kind of air valve.
Utility model content
The purpose of this utility model is to provide a kind of air valves, to solve existing air valve mentioned above in the background art
When in use, due to being used cooperatively with reciprocating vacuum pump, very high temperature is will produce, the service life of air valve is caused to subtract
It is short, and dust can be accumulated in the venthole of air valve when in use, so that the ventilatory capacity of air valve is declined ventilation hole plug
Problem.
To achieve the above object, the utility model provides the following technical solutions：A kind of air valve, including air valve cap and fixed gas
Pipe is provided with connecting hole on the inside of the air valve cap, is provided with fixing bolt on the inside of the connecting hole, the air valve cap it is interior
Portion is provided with air valve plate, and air valve seat is provided on the upside of the air valve cap, and the side of the air valve seat is provided with fixing nut, institute
The side for stating air valve cap is provided with cooling fin, and cover plate is provided on the outside of the air valve cap, be provided on the inside of the cover plate into
Stomata, the air valve cap are internally provided with air admission hole, and one end of the air admission hole is provided with air valve confinement block, the air valve limit
One end of clamp dog is provided with spring, and the side of the spring is provided with venthole.
Preferably, air channel is provided on the inside of the air valve cap, air valve confinement block is mounted in air channel.
Preferably, skewed slot is provided on the upside of the air valve confinement block, the height of air valve confinement block is the half of air channel,
And air channel is connect with venthole.
Preferably, the air admission hole is staggered with venthole.
Preferably, the fixed tracheae is hollow structure, and the both sides of lower end are provided with venthole.
Compared with prior art, the utility model has the beneficial effects that：By designing the cover plate on the outside of air valve cap and consolidating
Determine tracheae, after long-time use, many dusts can be accumulated in the inside of stomata, there is no gas to pass through nothing when cleaning
Method lifts air valve confinement block to being cleared up in stomata, carries out dismounting cleaning and bothers very much, passes through fixed tracheae and gas
Valve confinement block connects, and air valve confinement block is lifted when lifting cover plate, and then water flowing is rinsed again, when cleaning
There is no need to air valve whole dismounting, with regard to very convenient when cleaning, and by designing the cooling fin on air valve cap, pass through
Increase the heat dissipation for accelerating air valve with the contact area of air, anti-air-stopping valve overheat is damaged.
