The alarm detects that there is natural gas in the skid-mounted cover and then alarms. The first electric valve closes the natural gas in the storage tank and prevents it from flowing into the skid-mounted cover. The leaked natural gas in the skid-mounted cover enters the recovery box. The absence of natural gas in the skid-mounted cover avoids the maintenance personnel from inhaling too much natural gas during maintenance, causing bad consequences, and avoids static electricity fire caused by maintenance, causing serious consequences. The leaked natural gas is recovered to avoid waste of energy. The recovery component is separated from the skid-mounted cover, and the recovery box is moved, thereby facilitating the rapid movement and transportation of the recovered natural gas, saving physical strength and time.

The electric gate valve is simply to use an electric actuator to control the valve, so as to realize the opening and closing of the valve. It can be divided into two parts, the upper part is the electric actuator, and the lower part is the valve. The action torque is larger than that of the electric valve. The switching action speed of the electric gate valve can be adjusted, the structure is simple, and it is easy to maintain. During the action process, due to the buffering characteristics of the gas itself, it is not easy to be damaged by getting stuck, but there must be a gas source, and its control system is also more complicated than that of the electric valve.

The upper surface of the prying cover 10 is plugged into the alarm 16. The alarm 16 is a gas alarm, which is a gas leak detection alarm instrument. When flammable or toxic gas leaks in an industrial environment, and the gas alarm detects that the gas concentration reaches the critical point set by the explosion or poisoning alarm, the alarm 16 will send out an alarm signal to remind workers to take safety measures and drive the exhaust, cut-off, and spray systems to prevent explosions, fires, and poisoning accidents, thereby ensuring safe production.

During use, the skid-mounted seat 13 can be adjusted and moved in position through the fixing holes on the skid-mounted seat 13, which speeds up the installation of workers. The skid-mounted motor 11 drives the skid-mounted shaft 12 to rotate, so that the skid-mounted cover 10 is flipped open on the upper surface of the skid-mounted seat 13, so as to facilitate workers to install equipment and avoid rust caused by long-term exposure of the equipment and damage caused by debris and garbage entering the equipment. After long-term use, the equipment in the skid-mounted cover 10 is prone to aging and natural gas leakage. After the natural gas leaks, the staff cannot repair or replace it.

After the recovery box 1501 is recovered, the recovery component 15 is separated from the skid cover 10 by opening the first pipe clamp 14, and the recovery drive wheel 1504 drives the recovery universal wheel 1505 to move the recovery box 1501, so that the recovered natural gas can be quickly moved and transported, saving physical strength and time.

[0029] How this utility works:

[0030] During use, natural gas is stored in a gas station for refueling cars through a storage tank 1. By storing natural gas, it is inevitable that energy will exchange heat with the outside world, causing the temperature of the natural gas inside the storage tank 1 to rise. Therefore, part of the liquid evaporates to produce flash steam that gathers at the top of the storage tank 1. The third electric valve 6 is opened and closed at a fixed time to collect the flash steam in the storage tank 1 into the steam box 701 through the steam pipe 706. The flash steam is collected through the steam box 701. The steam pipe 706 is removed by opening the second pipe clamp 705. The steam box 701 is moved by driving the steam universal wheel 704 through the steam driving wheel 703. The second electric valve 5 at one end of the three-way pipe 4 is opened and closed. After the natural gas is used up, the second electric valve 5 can be connected to quickly add natural gas to the storage tank 1, and water is added to the inside of the water spray box 901, and the water in the water spray box 901 is rotated by the water spray pump 902 to spray water on the storage tank 1 through the water spray head on the water spray rack 8. After the cooling temperature becomes low, the water in the water spray box 901 is heated and heated by the heating plate 904, and the heated water in the water spray box 901 is rotated by the water spray pump 902 to spray water on the storage tank 1 through the water spray head on the water spray rack 8. Through the fixing holes on the skid-mounted seat 13, it is convenient to adjust the position and move the skid-mounted seat 13 during installation, which speeds up the installation speed of the workers, and the skid-mounted motor 11 drives the skid-mounted shaft 12 to rotate, so that the skid-mounted cover 10 The upper surface of the skid-mounted seat 13 is flipped open. After long-term use, the equipment in the skid-mounted cover 10 is prone to aging and causes natural gas leakage. After the natural gas leaks, the staff cannot repair or replace it. The alarm 16 detects that there is natural gas in the skid-mounted cover 10 and then sounds an alarm. When the first electric valve 2 is closed, the natural gas in the storage tank 1 cannot flow into the skid-mounted cover 10. The recovery pump 1502 rotates to extract the leaked natural gas in the skid-mounted cover 10 into the recovery box 1501. After the recovery box 1501 is recovered, the first pipe hoop 14 is opened to separate the recovery component 15 from the skid-mounted cover 10, and the recovery drive wheel 1504 drives the recovery universal wheel 1505 to move, thereby facilitating and quickly moving the recovered natural gas. The equipment saves physical strength and time in transportation. The equipment controls the temperature of the storage tank 1 according to different seasons and different temperatures, which is convenient for unified treatment of the flash steam in the steam box 701, avoiding the need for workers to go back and forth every day to treat the flash steam, greatly saving physical strength and time, avoiding direct flash steam discharge into the atmosphere to pollute the environment, collecting the flash steam to relieve the pressure inside the storage tank, avoiding the risk of explosion, facilitating workers to install equipment, and avoiding the equipment being exposed to the outside for a long time, causing rust, and debris and garbage entering the equipment, causing damage. After long-term use, the equipment in the skid-mounted cover 10 is prone to aging, causing natural gas leakage. After the natural gas leaks, the staff cannot repair or replace it, so there is no natural gas in the skid-mounted cover 10.This prevents maintenance personnel from inhaling too much natural gas during maintenance of the equipment in the skid-mounted cover 10, causing adverse consequences, and avoids static electricity ignition during maintenance, causing serious consequences, and recovers the leaked natural gas to avoid energy waste.

[0031] The electrical components mentioned in this article are all connected to an external main controller and 220V mains electricity, and the main controller can be a conventional known device for controlling a computer or the like.
