DETAILED DESCRIPTION

[0026] The present invention will be further described below in conjunction with specific embodiments. The present invention is explained by means of the illustrative embodiments and descriptions of the present invention, but is not intended to be limiting of the present invention.

[0028] The top of the diversion tube 103 is an inlet pipe, which is provided with a valve, and the bottom is an outlet pipe, which is connected to the cooling tube 107. Diversion pipes 118 are arranged around the outlet pipe. Each diversion pipe 118 is connected to a diversion visual bin 106 by a connecting pipe 108. Four diversion pipes 118 are evenly arranged around the circumference, and each diversion pipe 118 is provided with a valve. The number of connecting pipes 108 and diversion visual bins 106 corresponds to the number of diversion pipes 118.

[0029] The diverter visual bin 106 is fixedly mounted on the support 120, and the support 120 is fixedly mounted on the cooling tube 107. The diverter visual bin 106 is unidirectionally connected to the inside of the cooling tube 107, and a visual window is provided on the diverter visual bin 106. The bottom of the diverter visual bin 106 is fixedly connected to the connecting pipe 108, and a bottom one-way valve is provided at the bottom of the diverter visual bin 106; four outlets are provided on the side of the diverter visual bin 106, each of which is fixedly connected to the cooling tube 107, and a side one-way valve is provided in each outlet. The push rod is inserted from the top of the diverter visual bin 106 and slides in the diverter visual bin 106.

[0030] The push rod includes a pressure frame 105, and each of the four corners of the pressure frame 105 is fixedly connected to a pressure relief rod 119. Each pressure relief rod 119 is provided with a center hole. The pressure relief rod 119 is slidably installed on a long guide rod 117 using the center hole. The long guide rod 117 is fixedly installed on an annular plate 116, and the annular plate 116 is fixedly installed on the diversion cylinder 103. A pagoda-shaped spring 113 is also provided between the pressure frame 105 and the annular plate 116. One end of the pagoda-shaped spring 113 is fixedly connected to the annular plate 116, and the other end is fixedly connected to the pressure frame 105.

[0031] The bottom one-way valve includes a bottom valve plate 123, which is rotatably installed in the diversion visual chamber 106, and a torsion spring 124 is provided between the bottom valve plate 123 and the diversion visual chamber 106, one end of the torsion spring 124 is fixedly connected to the bottom valve plate 123, and the other end is fixedly connected to the diversion visual chamber 106, so that the bottom valve plate 123 can be rotated and reset; the side one-way valve includes a side valve plate 122, which is rotatably installed in the diversion visual chamber 106, and a torsion spring 124 is provided between the side valve plate 122 and the diversion visual chamber 106, and the above-mentioned torsion spring 124 has the same function.

[0032] A cooling interlayer 121 is provided inside the cooling cylinder 107. The cooling interlayer 121 is a circular cavity. The circular cavity is coaxial with the cooling cylinder 107. Four rectangular extension cavities are evenly arranged around the circumference of the circular cavity. The extension cavities protrude from the outer wall of the cooling cylinder 107. One of the extension cavities is connected to an intake water pipe 115, which is fixedly connected to an intake water pump 114. The intake water pump 114 is also connected to the water tank 109. The other extension cavity is connected to an extraction pipe 112, which is fixedly connected to an extraction water pump 111. The extraction water pump 111 is connected to the water tank 109. The water tank 109 is fixedly installed on the support seat 101 and is provided at the bottom of the cooling cylinder 107.

[0033] An outlet pressure gauge 125 and a second thermometer 126 are also fixedly installed on the cooling cylinder 107, and a first thermometer 102 and an inlet pressure gauge 104 are also fixedly installed on the diversion cylinder 103. The above pressure gauges and temperatures are used to detect pressure and temperature respectively. A water inlet pipe is also provided on the water tank 109, and a valve is provided on the water inlet pipe. A trumpet-shaped water outlet is also provided on the other side of the water tank 109.

[0034] The working principle of the present invention is as follows: the inlet pipe of the diverter cylinder 103 is connected to the oil outlet end of the output pipeline of the refueling truck, and cold water is added into the water tank 109 at the same time, and the valve of the inlet pipe and the valve on the diverter pipe 118 are opened. The wider the valve on the diverter pipe 118 is opened, the greater the amount of oil passing through, and the greater the pressure relief ability. When the oil enters, huge pressure will be generated due to the excessively high oil temperature and the excessively fast oil speed. At this time, after the oil passes through the inlet pipe of the diverter cylinder 103, a part of the oil directly enters the cooling cylinder 107 and the oil outlet pipe 110 from the outlet pipe of the diverter cylinder 103.

[0035] The remaining part will enter the diversion visual chamber 106 from the diversion pipe 118 and the connecting pipe 108, and push the pressure frame 105 to slide. Under the force of the reaction force of the pagoda-shaped spring 113, the oil pressure and the force of the pagoda-shaped spring 113 are balanced. At this time, the pressure frame 105 also stops sliding, and the entering oil will push the side valve plate 122 from the side wall of the diversion visual chamber 106, and then enter the diversion visual chamber 106, merge with the oil that entered the cooling cylinder 107 before, and flow out from the oil outlet pipe 110 together.

[0036] When the pressure is greater, the position of the pressure frame 105 moves further, the more outlets of the side wall of the diversion visible chamber 106 are exposed, and the more outlets for pressure relief are present. When the oil enters the cooling cylinder 107, it is necessary to start the water pump 114 to discharge the water in the water tank 109 into the cooling interlayer 121 through the water pump 115, and start the water pump 111 to pump out the water in the cooling interlayer 121 to achieve water circulation, so that the oil directly flowing out from the outlet pipe of the diversion cylinder 103 and the oil entering from the diversion visible chamber 106 will come into contact with the cooling interlayer 121, and the heat generated will also be taken away by the cold water in the cooling interlayer 121 to prevent high temperature and high pressure.

[0037] Any matters not described in the present invention are applicable to the prior art.
