The one end and the drain pipe 2 intercommunication of liquid return pipe 4, and communicate and be provided with the downstream section of flowmeter 3 on drain pipe 2, the other end and the liquid storage pot 1 intercommunication of liquid return pipe 4. The liquid return pipe 4 is used for guiding the gas in the system pipeline back to the liquid storage tank 1 before loading, so that the gas is prevented from influencing the accuracy of the product loading metering.
In the present embodiment, the liquid storage tank 1 is used for storing liquid products to be loaded, and the liquid storage tank 1 is generally installed at a higher position, i.e. the liquid outlet at the lower part of the liquid storage tank 1 is higher than the height of the tank car 13, so as to facilitate liquid outlet. The liquid storage tank 1 is provided with a liquid level meter 6, and the liquid level meter 6 is used for detecting the liquid level in the liquid storage tank 1 and primarily metering the amount of liquid discharging and loading according to the descending of the liquid level. Because the liquid storage tank 1 is large in volume and high in height, preferably, in the embodiment, the two liquid level meters 6 are arranged, and the two liquid level meters 6 are respectively arranged at the middle part and the bottom part of the liquid storage tank 1, so that the liquid level measuring range of detection is increased, and the accuracy of liquid outlet measurement is improved. In other embodiments, the number of fluid level gauges 6 may be specifically selected based on the volume and height of the fluid reservoir 1.
One end of the liquid outlet pipe 2 is communicated with a liquid outlet at the bottom of the liquid storage tank 1, and the other end is communicated with the tank truck 13. Besides the flowmeter 3, a liquid pump 7 is arranged on the liquid outlet pipe 2. The liquid pump 7 is a power device of a liquid loading system and is used for pumping liquid in the liquid storage tank 1 to the tank truck 13. A liquid pump 7 is mounted on the outlet pipe 2 upstream of the flow meter 3 to facilitate smooth pumping of the liquid product. In this embodiment, the liquid pump 7 is a corrosion-resistant pump to prevent the chemical liquid from corroding the pump body. Preferably, the liquid pump 7 selects a diaphragm pump, the diaphragm pump completely separates the materials from the outside in the conveying process, is strong in corrosion resistance, does not cause environmental pollution, and is suitable for conveying various corrosive liquids, liquids with particles and high-viscosity, volatile and highly toxic liquids.
In the present embodiment, the flowmeter 3 is a coriolis-type mass flowmeter, i.e., an LZYN-type mass flowmeter. The LZYN type mass flowmeter measures flow by utilizing the Coriolis principle, has the advantages of high measurement accuracy, good repeatability and wide range of measurement, and can obviously improve the measurement precision of loading liquid products.
LZYN type mass flow meter need install just can guarantee its measurement accuracy under the less operating mode of vibration, consequently, in this embodiment, is provided with damping device 5 in the one end of drain pipe 2 with tank car 13 intercommunication to reduce drain pipe 2 and LZYN type mass flow meter's vibration.

The filter 8 is used for filtering the liquid, and can effectively reduce the adhesion of impurities on the flowmeter 3, thereby avoiding influencing the metering. The filter 8 can reduce the pulse impact of the liquid pumped by the liquid pump 7 on the flow meter 3, and reduce the vibration of the flow meter 3.
Further, a liquid outlet valve 9, a first stop valve 11, a second stop valve 12, and a third stop valve 14 are provided in the liquid outlet pipe 2. The liquid outlet valve 9 is arranged on the liquid outlet pipe 2 below the liquid storage tank 1 and is used for controlling the liquid outlet of the liquid storage tank 1. The first stop valve 11 is installed between the liquid outlet valve 9 and the liquid pump 7 for protecting the liquid pump 7 and preventing the liquid pump 7 from idling. A second shut-off valve 12 is installed between the filter 8 and the flow meter 3 for protecting the flow meter 3. A third stop valve 14 is mounted between flow meter 3 and tank car 13 for controlling the feed of liquid from liquid outlet pipe 2 to tank car 13.
In this embodiment, the liquid return pipe 4 is used to form a loop for liquid return, and the system is emptied of gas to prevent the gas from affecting the flow meter 3, thereby ensuring accurate loading metering. One end of the liquid return pipe 4 is communicated with the liquid outlet pipe 2 at the downstream of the flowmeter 3, and the other end is communicated with the upper part of the liquid storage tank 1. The liquid return pipe 4 is provided with a liquid return valve 10, and the liquid return valve 10 is used for controlling the on-off of a liquid return passage. Before each loading, the liquid return valve 10 is opened, and the third stop valve 14 is closed to conduct a liquid return passage and close a liquid inlet passage to the tank car 13, so that gas remained in the liquid outlet pipe 2 can be effectively emptied. After the gas is emptied, the truck is reloaded, and the accuracy of the loading and metering is ensured.
The working principle of the liquid loading system provided by the embodiment of the utility model is described below with the accompanying drawings:
before loading, the third stop valve 14 is closed, the liquid outlet valve 9, the first stop valve 11, the second stop valve 12, and the liquid return valve 10 are opened, and the liquid pump 7 is started. After the liquid pump 7 works for 5-10 minutes, the gas in the liquid outlet pipe 2 is replaced and emptied, the liquid return valve 10 is closed, the third stop valve 14 is opened, and loading is started. The LZYN type mass flowmeter detects the flow in real time in the loading process, and after a liquid product with a set flow is filled, the liquid pump 7 is closed to finish the loading process.
In the process, the gas in the liquid outlet pipe 2 is emptied in advance, and the system adopts the LZYN type mass flow meter, so that higher loading metering precision is ensured, and the requirements of customers are met.
