The invention provides an inflation process of a rubber air bag, which comprises the following steps:
the method comprises the following steps: through the cooperation between air compressor machine, gas holder and the rubber gasbag, realize filling the gassing operation to the gasbag under the surface of water as follows specifically:
the air compressor is fixedly installed on the land, the air storage tank is installed on the movable steel floating body, when the steel floating body is on the shore, the air storage tank is connected with the air compressor through the high-pressure hose, the steel floating body is close to the shore and stores compressed air into the air storage tank to be full of certain pressure through the air compressor, the process is that the piston moves upwards from the lower dead point, the suction valve and the exhaust valve are in a closed state, gas is compressed in the closed cylinder, and the pressure and the temperature gradually increase until the pressure of the gas in the cylinder is equal to the exhaust pressure due to the fact that the volume of the cylinder is gradually reduced. When the steel floating body sails to the sea, compressed air in the air storage tank is decompressed and discharged into the rubber air bag, the piston continues to move upwards, so that the gas pressure in the cylinder is greater than the exhaust pressure, the exhaust valve is opened, and the gas in the cylinder is discharged out of the cylinder at equal pressure under the pushing of the piston and enters the exhaust pipeline until the piston moves to the top dead center. At the moment, due to the action of the spring force of the exhaust valve and the gravity of the valve plate, the closing and the exhausting of the exhaust valve are finished, and the exhaust amount calculation formula is as follows:
wherein z is the number of cylinders, n is the number of revolutions, S is the piston stroke, and D is the cylinder diameter.
In the actual process, the amount of air exhausted to the rubber air bag due to the existence of the clearance is always smaller than the displacement of the piston, so the actual exhaust amount is shown by the following formula:
V R ＝η v gV k
in the formula eta v In order to obtain the gas transmission coefficient,
according to empirical formula
In the formula, P 1 Is the initial pressure, P 2 For the final pressure, m is a polytropic exponent obtained by looking up a table。
To this end, the air compressor completes a work cycle consisting of three processes of suction, compression and exhaust.
According to the gaseous equation P 1 V 1 ＝P 2 V 2 In which P is 1 At atmospheric pressure (P) per minute 1 ＝1kg/m 2 )；P 2 Is the discharge pressure P of the air compressor 3 Then P is 2 ＝P 1 +P 3 ；V 1 The air displacement of the air compressor is measured;
so can be converted into formula
Then according to the formula
Obtaining the inflation time, wherein T is the inflation time; v is the volume of the gas storage tank.
Namely, the inflation process of the rubber air bag is completed. Meanwhile, the check valve at the air inlet of the rubber air bag is used for preventing air from flowing backwards, so that accidents are reduced. When the air-bleeding operation is needed, the air in the air sac can be discharged by utilizing the relief valve of the air inlet of the rubber air sac. The connection between the air storage tank and the air bag is connected through an air conveying hose, and the air conveying hose is provided with a manual pressure relief valve so as to control the pressure in the air inlet pipeline, prevent the pressure from exceeding the limit value range and prevent accidents.
Step two: through the atmospheric pressure changer of installing at rubber air bag air inlet, supply remote monitoring gasbag pressure, the numerical value that will monitor shows through visual panel, concrete step as follows:
the intelligent monitoring link is that the pressure transmitter uses dry and clean compressed air as energy source to convert the measured pressure into 0.02-0.1MPa pressure signal for transmission to the unit combined instrument for indication, record or regulation. When measured pressure P 1 、P 2 Respectively enter the high-pressure chamber and the low-pressure chamber, and P is arranged under the working condition 1 ＞P 2 A force is generated on the diaphragm. This force actsThe connecting rod acts on the lower end of the main lever, the lever rotates clockwise by the moment generated by taking the sealing sheet as a pivot, and the thimble frame fixed on the upper side of the main lever also rotates along with the rotation. Then, the gap between the baffle and the nozzle is reduced, so that the back pressure of the nozzle is increased, the output pressure P of the amplifier is increased, the output pressure enters the feedback corrugated pipe, a force is generated at a feedback fulcrum and acts on the main lever, the sealing sheet is used as the fulcrum, the counterclockwise moment is generated, and the baffle is further away from the nozzle. When all the moment shafts are balanced, the main lever is stabilized at a new balance position, and the gap between the nozzle and the baffle plate is stabilized. Thus, the amplifier can output a pressure signal proportional to the measured differential pressure. Therefore, the reading of the pressure change condition by the visual panel is realized, and the safety of the inflation and deflation process is ensured.
Step three: through the electronic stop valve of taking manual switch and electric switch, control the gas output in the rubber gasbag, when atmospheric pressure in the rubber gasbag exceeded the settlement threshold value simultaneously, the relief valve was opened automatically and is let off a load, and concrete step is as follows:
the air pressure in the rubber air bag can be controlled by the electric thrust of the electric stop valve to rotate the valve rod, so that the sealing surface of the valve clack is tightly attached to the sealing surface of the valve seat, and the medium is prevented from flowing. And then the abnormal air pressure change in the rubber air bag is observed through the visual panel, and when the abnormal air pressure change exceeds a set safety threshold, the safety valve can directly overcome the mechanical load acting on the valve clack by the force generated by the medium pressure to open the safety valve, so that the load relief operation is carried out, and the pressure in the rubber air bag is restored to a safety value.
According to the invention, the rubber air bags arranged in front of the bridge piers of the bridge can be connected into rows by the high-friction blocking ropes, and the rubber air bags are inflated to drive the high-friction blocking ropes to float out of the water surface together for blocking objects (ships or large floaters) passing through the area, so that the bridge piers are prevented from being impacted by the ships; the method comprises the steps of collecting a target object on the water surface at a safe distance in front of a pier, controlling the inflation speed to enable a rubber air bag and a high-friction blocking rope to completely float out of the water surface before the target object arrives according to the volume, the speed and the direction of the target object, the water level and the position of the air bag under water according to the inflation process mentioned in the invention, and achieving the effect of blocking the target object.
