Description
Technical Field
The invention relates to a high-pressure air source device, in particular to a pilot valve pressurized quick-plug type high-pressure energy storage cylinder and a high-pressure air source device.
Background
In some special applications, a high pressure air source device is required to power the actuator. For example, the following situations:
1. in the warplane auxiliary fuel tank hanging frame and the missile launching hanging frame, a high-pressure air source device is installed, and the high-pressure air source device is opened at a specific moment through the operation of a pilot in a cabin to drive a piston in a cylinder on the hanging frame to move to open a locking device, so that the auxiliary fuel tank or the missile is separated from the hanging frame.
2. The individual missile launcher also requires a high pressure air source device to provide initial power to fly the projectile off the launcher.
The prior high-pressure air source device such as a battlefield auxiliary oil tank throwing and missile reflecting off frame consists of two parts, wherein the first part is an air bottle support assembly A, and as shown in an attached drawing 10 of the specification, accessories such as an air supply jack A1, an electromagnetic valve A2, a control circuit plug socket A3, a pipeline part A4 and the like are arranged and fixed in a certain cabin of the battlefield and can be detached during maintenance. The second part is a high-pressure energy storage gas bottle B, which is shown in the figure 11 of the specification and consists of accessories such as a quick plug B1, a bottle body B2, a pressure gauge B3 and the like. In order to ensure safety, the high-pressure energy storage gas bottle is filled with high-pressure gas at ordinary times and then is separated from a fighter for independent storage, the fighter is quickly inserted into a gas bottle bracket by ground staff before being lifted, and a valve B4 in the gas bottle is manually opened to supply gas for an electromagnetic valve; after the fighter performs a task (or trains) and falls to the ground, the ground crew rapidly pulls out the high-pressure energy storage gas cylinder under the pressure state (when the fighter lifts off to train, if the auxiliary oil tank is not thrown or the missile is launched, the pressure of the gas cylinder is slightly reduced, but still is in the high-pressure state, about 29 MPa), and the gas cylinder is replenished to the specified pressure for the next use. The under-pressure plug means that an empty gas cylinder cannot be filled in a reproduction field on a fighter (before the fighter is lifted off), or the high-pressure gas in the gas cylinder can be completely emptied (after the fighter falls on the ground) and then safely pulled down, so that the fighter cannot lift off or transfer in time due to certain danger and overlong time consumption in operation, and the fighter efficiency is seriously affected.
The existing high-pressure energy storage gas cylinder has the following defects:
1. the plugging speed is not fast enough: in the existing high-pressure energy storage gas cylinder, mark positions are made on the gas cylinder and a gas cylinder bracket, a ground crew can insert and pull out the gas cylinder under the condition that the mark positions are accurately aligned visually, if tasks are executed at night or on-site light is poor, the speed is slower, and real-sense rapid blind insertion and blind pulling cannot be realized;
2. the existing high-pressure energy storage gas cylinder has complex sealing structure, low reliability and large 24-hour pressure drop, and is at least more than 0.05MPa;
3. the maintenance performance is poor: because the internal structure of the existing high-pressure energy storage gas cylinder is complex, sealing elements are scattered in the gas cylinder, once the high-pressure energy storage gas cylinder has the sealing leakage problem, the high-pressure energy storage gas cylinder can only be returned to a factory for maintenance, so that more whole cylinders are needed for backup, and the cost is increased.

The specific implementation method comprises the following steps:
when the gas cylinder is installed, the fast plug assembly at the front end of the gas cylinder filled with gas is inserted into the gas supply jack for supplying gas to the electromagnetic valve, the handle at the tail of the gas cylinder is rotated clockwise by hands to drive the fast plug assembly to continuously enter, the ejector rod is pushed under the action of the valve rod in the entering process, the pilot valve is opened firstly, the main valve is locked after being pushed in place continuously, the main valve is thoroughly opened at the moment, the first sealing structure and the second sealing structure are invalid, and the third sealing structure and the fourth sealing structure play a sealing role.
When the gas cylinder is pulled out, the tail handle is rotated anticlockwise, and the gas cylinder is unlocked under the action of aerodynamic force and the spring component; continuing to rotate; the pilot valve is closed firstly, then the main valve is closed again, and high-pressure gas in the bottle is stored; and continuously rotating, discharging residual high-pressure gas, and safely pulling out.
The stress analysis of the pilot-operated opening mode adopted by the invention is as follows:
the diameter of the first prop is 4mm, the aperture of the exhaust blind hole is 0.5mm, and the contact line diameter of the first sealing structure of the pilot valve in the main valve is 4mm, so that 30MPa high-pressure gas is sealed in the bottle.
The instantaneous maximum aerodynamic force to open the pilot trap is: 3.14x2x2x30=377 newtons, the spring force of the spring assembly is about 60 newtons, and the total force is 437 newtons.
After the pilot valve is opened, the pneumatic resistance of 377 cattle is disappeared, and only 60 cattle of spring force is remained; at the same time, aerodynamic resistance of 377 newtons is generated again at the third sealing structure, and the resultant force is 437 newtons.
In this application, the gas cylinder is installed through butt joint locking nail 2010 and the mode of helicla-tupe spiral locking, is pushed up by the valve rod, and the screw-in is screwed out the gas cylinder and is controlled opening and closing of gas cylinder, and under the extreme condition of dry friction, torsion when opening 30 MPa's gas cylinder is only about 45 newtons, and the resistance is minimum, only needs the handle operation of holding of single hand can.
The stress analysis of the traditional opening mode adopting direct action is as follows:
the bottle is filled with 30MPa high-pressure gas, the diameter of the valve is 8mm, and the diameter of the valve is 10mm.
As shown in fig. 12, the valve is in a closed state, the channel a is connected to a sealed container, the channel a, the sealed container and the valve stem are in a normal pressure state (0.1 MPa), the valve is subjected to an air pressure f1=3.14×5×5×30-0.1) = 2347.2 n, the valve stem is subjected to an air pressure f2=3.14×4×30-0.1) = 1502.2 n, the valve stem is subjected to an air pressure f3=f1-f2= 2347.2-1502.2 =845 n, and the valve stem is subjected to an air pressure f2=3.14×4×4 n (30-0.1) = 1502.2 n, and the resultant force f3=f1-f2= 2347.2-1502.2 =845 n, the resultant force is to the left, so that the valve tends to be closed, and the initial resistance to be overcome when the valve is opened.
The force applied when opening the valve is analyzed as follows:
as shown in fig. 13, the pressure of the high-pressure gas reaches the sealed normal pressure container connected with the high-pressure gas through the channel a, the pressure tends to be balanced, if the pressure after the balancing is 29.9MPa, the pressure of the left end face and the right end face of the valve is the same, the pressure f1=0 n, the pressure f2=3.14x4x4 (29.9-0.1) = 1497.2 n, the direction is rightward, and the resultant force f4=f2-f1= 1497.2 n, the direction is rightward, and the resultant force is the initial resistance to be overcome when the valve is closed.
From the above analysis, it can be seen that the resistance to be overcome when opening and closing the shutter is large when using the direct-acting shutter, which is difficult to be done by hand without the aid of a mechanical force-increasing mechanism. Reducing the diameter of the channel a may reduce the opening resistance, but the flow area (flow rate) is reduced; reducing the diameter of the valve stem can reduce the closing resistance, but the mechanical strength of the valve stem is reduced, the risk of breakage is increased, and the processing of the seal ring groove becomes very difficult. The valve rod is arranged in the bottle body, and is always subjected to air pressure resistance when closed, so that the design structure is not changed, and the resistance can not be eliminated forever; the valve rod needs to extend out of the bottle body from the inside of the bottle body, occupies the effective volume of the bottle body, and increases the volume, the weight and the size of the whole system.
The gas cylinder adopts an opening mode of a pilot valve and a main valve, and the installation position of the valve rod is adjusted from the inside of the gas cylinder to the outside of the gas cylinder without being affected by the pressure of the gas; the effective volume of the bottle body is not occupied.
The foregoing description is only illustrative of the present invention and is not intended to limit the scope of the invention, and all equivalent structures or equivalent processes or direct or indirect application in other related arts are included in the scope of the present invention.
