Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.

Referring to fig. 1-4, a christmas tree pressure measuring device for land oil production comprises a christmas tree body 1 and a pressure measuring mechanism 2, wherein a shunt pipe 3 is communicated with the side wall of the christmas tree body 1, a valve 4 is arranged on the shunt pipe 3, a first connecting disc 5 is fixedly installed at the outlet end of the shunt pipe 3, and a sealing mechanism is arranged on the first connecting disc 5.

Wherein, sealing mechanism is including offering the recess 12 on the first flange 5 lateral wall, and fixed mounting has sealing strip 13 in the recess 12, and further, recess 12 is the annular setting.

When the second land 8 is in contact with the first land 5, the second land 8 presses the weather strip 13, thereby enhancing the sealing property between the first land 5 and the second land 8.

The first connecting disc 5 is provided with a threaded hole 6 in a penetrating mode, an external threaded pipe 7 is connected to the threaded hole 6 in an internal thread mode, a second connecting disc 8 is fixedly sleeved on the external threaded pipe 7, the outlet end of the pressure measuring mechanism 2 is fixedly installed on the side wall of the second connecting disc 8, and two pressing mechanisms which are in contact with the second connecting disc 8 are fixedly installed on the side wall of the first connecting disc 5.

Wherein, hold-down mechanism includes fixed block 14 on fixed mounting and the 5 lateral walls of first flange, and 14 internal threads of fixed block run through and are equipped with screw rod 15, and the bottom of screw rod 15 is rotated and is connected with the clamp plate 16 that sets up with 5 lateral walls sliding contact of first flange, and is further, and clamp plate 16 is the arc setting.

It should be noted that the external threaded pipe 7 is in threaded connection with the threaded hole 6, so that the first connecting disc 5 and the second connecting disc 8 are arranged in abutting contact, and then the two screws 15 are rotated, so that the two pressing plates 16 press the second connecting disc 8, and the purpose of facilitating installation and enhancing the stability of the connecting disc is achieved.
