[0007] Preferably, a threaded opening is provided on one side of the connecting pipe, and a pressure bolt is inserted into the inner thread of the threaded opening.

[0008] Preferably, the locking nut is a hexagonal nut.

[0009] Preferably, the support tube is fixedly connected to the top of the locking nut, and the support tube is communicated with the inner hole of the locking nut.

[0010] Compared with the prior art, the beneficial effects of the utility model are:

[0011] The easily disassembled and assembled valve pressure measuring seat is fixedly connected to the gas pipeline through the delivery pipe on the bottom of the base plate, and then the locking nut is screwed on the connecting pipe for communication, and the gas meter is fixed through the supporting pipe on the top of the supporting pipe. During the fixing operation, the sealing piece on the bottom of the locking nut is pressed against the base plate to achieve the sealing of the connection, and the supporting pipe can slide in the supporting pipe to achieve the height adjustment of the gas meter. After adjustment, the height of the supporting pipe can be fixed by rotating the pressing bolt into the screw hole to press the outer wall of the supporting pipe. The utility model has a simple structure and is easy to install and maintain. BRIEF DESCRIPTION OF THE DRAWINGS
