The Role Of Air Valves in The Air Pneumatic Shaft

Air nozzle is the gas expansion shaft in the deflation and inflation will be used to an accessory, it mainly plays the function of inflation and deflation, because the gas expansion axis in the working process need to often need to inflate or deflate, first of all, the inflatable handle should be aligned with the gas expansion axis on the gas nozzle inflatable, deflation should also be against the gas expansion axis gas nozzle to slide the gas core can be deflated, so that the key bar will return to the initial appearance.

Pneumatic valve specifications:
Air nozzle also has a classification of the first to look at the convex type (A type) is the top of the middle of the high part of the pointed type; concave point type (B type) of the top of the middle of the high part of the concave type. Air nozzle specifications are G1/4 thread; G3/8 thread; G1/8 thread; M14*x1.5 thread; M14x1 thread, gas expansion axis inflatable nozzle designation: G1/4-A type, G1/8-B type, M14x1.5-A type, M14*1.5-B type, these are common threaded teeth specifications for special size specifications for the product will not be more today for the introduction. The material of air nozzle is made of full copper, so it has a long service life and fine workmanship.

The role of the gas nozzle in the gas expansion axis: gas expansion axis gas nozzle is installed on the surface of the gas expansion axis components, belonging to the gas inflatable and air intake of the special outlet, mainly play a role in sealing and deflating.
(1) fullness powerful
The gas expansion shaft uses the gas nozzle inflatable, can be intact full, and can save time, so in the inflatable operation time is short. The fullness is also very strong, which can make the air expansion shaft operate with less malfunction.
2) Less likely to leak airflow
The use of air nozzle inflatable can grasp the air flow can be concentrated, according to the direction of the inflatable wind flow can be more directly through the air nozzle to the air expansion axis, not easy to leak, not easy to outward flow of air flow, and better to make the work of the air expansion axis more perfect.

Where does the air nozzle of the air expansion shaft open:
1) The role of the air nozzle of the air expansion shaft is the key opening for inflating the air bag and allowing the expansion part to expand and contract;
2) The location of the opening of the air nozzle in the air expansion shaft is usually in the shaft body near the head part, the head part, the head port, and so on;
3) The sealing of the air nozzle must be very good, because if there is a gap, it will lead to air leakage;
4) There must be no impurities in the air nozzle area to avoid clogging or puncturing the airbag;
5) The inflation time and air pressure of the airbag should be reasonable, over-inflation will lead to shrinking the service life of the airbag and increase the risk of bursting.

The use of air expansion shaft air nozzle:
1) First of all, in terms of design, many people feel that the design of two inflatable nozzles will be more convenient, we suggest that it is best to design an air nozzle can be, two air nozzles in the later use, increase the chances of air leakage;
2) air up shaft in use, only need to provide their own air source, with an air gun to the inflatable nozzle, the airbag inflatable expansion, popping out of the key bar or hold up the plate sheet clamping the paper tube can work;
3) When it is necessary to dismantle the roll, you only need to press the air nozzle position for 2-3 seconds to complete the deflation of the air expansion shaft and remove the roll (paper tube).

The reasons for air leakage from the air expanding shaft, are as follows: One of the reasons is air leakage from the air nozzle.
1) Hose rupture, there may be quality problems with the hose itself, you need to remove the shaft head and replace it with a new hose
2) Seal ring gap, this situation needs to be sealed in the sealant to be sealed
3) the pressure ring is loose, just tighten the pressure ring, pay attention to the usual to always observe whether the loose
4) inflatable nozzle part of the leakage, this time to replace and then install on it.

Requirements of pneumatic expansion shaft for air valve:
Gas Expansion Shaft is a common industrial equipment which is widely used in many fields. The function of the pneumatic shaft is to inject gas into the shaft through the gas nozzle for the purpose of fixing, supporting and transmission. However, in order to ensure the normal operation of the pneumatic shaft, there are certain requirements for the gas nozzle.
First of all, the nozzle should have good airtight performance to effectively prevent gas leakage. This is because a certain pressure needs to be maintained in the pneumatic shaft, if the nozzle loses its sealing performance, it will lead to a drop in air pressure, which will affect the working effect of the pneumatic shaft.
Secondly, the nozzle should have a certain pressure resistance, able to withstand the high-pressure gas inside the pneumatic expansion shaft. Generally speaking, the working pressure of the shaft is relatively high, so the nozzle must have enough pressure capacity to ensure that the gas will not leak or cause damage to the nozzle.
In addition, the material of the nozzle is very important. Generally speaking, the material of the nozzle should be corrosion-resistant and wear-resistant materials, such as stainless steel, ceramic and so on. This ensures that the nozzle has a long service life and does not affect the normal operation of the pneumatic shaft because of the material.
In summary, the air nozzle for the pneumatic expansion shaft has high requirements, and needs to have good airtight performance, sufficient pressure resistance and excellent material selection. This will ensure the normal operation of the pneumatic shaft, improve the working efficiency and reduce the maintenance cost.
