DETAILED DESCRIPTION

[0014] Example:

[0015] like Figure 1 The present embodiment provides a concrete pumping pressure regulating device, comprising a main pumping pipe 1, wherein the main pumping pipe 1 comprises a feed pipe 1a and a discharge pipe 1b, wherein a middle connecting pipe 2, a first side connecting pipe 3 and a second side connecting pipe 4 are arranged between the feed pipe 1a and the discharge pipe 1b, wherein the first side connecting pipe 3 is provided with a first control valve 5, and the second side connecting pipe 4 is provided with a second control valve 6. The first side connecting pipe 3 and the second side connecting pipe 4 have the same inner diameter. The inner diameter of the middle connecting pipe 2 is twice the inner diameter of the first side connecting pipe 3 and the second side connecting pipe 4. The feed pipe 1a, the discharge pipe 1b and the middle connecting pipe 2 are coaxially arranged. A first connecting flange 7 is provided at the end of the feed pipe 1a. A second connecting flange 8 is provided at the end of the discharge pipe 1b.

[0016] When this embodiment is in use, the device is installed on the pumping pipe at the end through the first connecting flange 7, and the second connecting flange 8 is connected to the pouring device. The construction personnel choose to open and close the first control valve 5 and the second control valve 6 according to the construction needs of the site, so as to control the concrete pressure and flow of the pumping pipe.
