Description

Technical Field

[0002] In recent years, the installation of PERT floor heating pipes has increased. The most important thing for PERT floor heating pipes is that the pipes should not be damaged during use. During the production and transportation of PERT pipes, the pipes are often damaged due to external forces or other reasons during transportation, and it is not easy to find, causing certain economic losses after installation. Therefore, pipeline manufacturers often pressurize the pipes before packaging, and check whether the pipes have air pressure before construction to determine whether there are quality problems with the pipes.

[0003] The existing pressure testing is generally as follows: the tail end of the pipe is sealed by heating, the head end of the pipe is connected to the compressed air pipeline, the air pressure is first raised to the high pressure area for pressure testing, the pressure is maintained for a certain period of time, and then the air is exhausted. After the pressure is released to a lower pressure value, the head end of the pipe is sealed by heating and sealing, and the lower safety air pressure in the pipe is retained as a quality inspection item before paving to ensure the quality of the product before paving. However, during the pressure relief and exhaust process of the pressure test operation, the high-pressure gas in the pipe is directly emptied without being collected and reused, and the high-pressure gas during the exhaust process will also produce a lot of noise.

DETAILED DESCRIPTION

[0028] The following will be combined with the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 The utility model provides a technical solution: an environmentally friendly and energy-saving pressure device for floor heating pipes, comprising a high-pressure tank 3, one end of the high-pressure tank 3 is connected to a high-pressure air pump 1 through a second connecting pipe 16, a valve B9 is provided on the second connecting pipe 16, the other end of the high-pressure tank 3 is connected to a pressure platform 5 through a fifth connecting pipe 19, a valve E12 is provided on the fifth connecting pipe 19, the same end of the high-pressure air pump 1 is connected to a medium-pressure tank 2 through a first connecting pipe 15, a valve A8 is provided on the first connecting pipe 15, and the other end of the medium-pressure tank 2 is connected to a pressure platform 5 through a fifth connecting pipe 19, a valve E12 is provided on the fifth connecting pipe 19, and ... other end of the medium-pressure tank 2 is connected to a pressure platform 5 through a The first end of the high-pressure air pump 1 is connected to the pressing platform 5 through the fourth connecting pipe 18, and the valve D11 is installed on the fourth connecting pipe 18. The same end of the high-pressure air pump 1 is connected to the low-pressure tank 4 through the third connecting pipe 17, and the valve C10 is installed on the third connecting pipe 17. The other end of the low-pressure tank 4 is connected to the pressing platform 5 through the sixth connecting pipe 20, and the valve F13 is installed on the sixth connecting pipe 20. The other end of the high-pressure air pump 1 is connected to the natural air through the air intake pipe 14, and the valve G7 and the air filter 6 are installed on the air intake pipe 14.

[0030] Through the environmentally friendly and energy-saving pressurizing device of the floor heating pipe, the remaining gas after the pressurizing of the pressurizing platform 5 is collected in order into different gas storage tanks, and the gas in the gas storage tanks is then transported to the high-pressure air pump 1 for pressurization for reuse by the pressurizing platform 5. Through the automatic pressurizing device, the recovery of the remaining pressurized gas is achieved, the pressurizing efficiency of the pipe is improved, the noise pollution is reduced, and electricity is saved.

[0031] When the device is producing gas, when the high-pressure air pump 1 starts working, valve A8 opens, and the gas in the medium-pressure tank 2 enters the high-pressure air pump 1. After being pressurized by the high-pressure air pump 1, the gas enters the high-pressure tank 3 through valve B9. When the gas pressure in the medium-pressure tank 2 is lower than 0.4MPa, valve A8 is closed; valve C10 opens, and the low-pressure tank 4 continues to supply gas to the high-pressure air pump 1. The gas enters the high-pressure tank 3 through valve B9 after being pressurized. When the gas in the low-pressure tank 4 is lower than 0.1MPa, valve C10 is closed. At this time, if the air pressure in the high-pressure tank 3 is still insufficient, the high-pressure air pump 1 takes air from the natural air for pressurization until the high-pressure tank 3 reaches the set value, valve G7 is closed, and the high-pressure air pump 1 stops working.

[0032] When the device pressurizes the pipe, the pipe is connected to the pressing platform 5, the pressing platform switch is started, the valve E12 is opened, and the gas in the high-pressure tank 3 enters the pressing platform 5 through the fifth connecting pipe 19 for pressing. After being pressurized to the set pressure, the pressure is maintained, and the valve E12 is closed. When exhausting, the valve D11 is opened, and the gas in the pressing platform 5 enters the medium-pressure tank 2 through the fourth connecting pipe 18. When the gas in the medium-pressure tank 2 is greater than 0.8MPa, the valve D11 is closed first, and the valve F13 is opened later. After the remaining low-pressure gas in the pressing platform enters the low-pressure tank 4 through the sixth connecting pipe 20, the pipe port is heat-sealed to complete the pipe pressing.

[0033] When there are multiple pressing platforms 5, the pressing platforms 5 are connected to the medium-pressure tank 2, the high-pressure tank 3, and the low-pressure tank 4 in the same way. The working principles of the various pressing platforms are the same and they do not affect each other.

[0034] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
