Anti-freezing pressure measuring device for gas field

The utility model discloses an anti-freezing pressure measuring device for a gas field. The anti-freezing pressure measuring device comprises a shell; the inner body is arranged in the outer shell, and the space between the outer shell and the inner body is filled with an anti-freezing solution; the receiving end of the pressure measuring instrument is inserted into the inner body; the piston is arranged in the inner body, and the space between the upper end of the piston and the top of the inner body is filled with anti-freezing liquid. The anti-freezing pressure measuring device for the gas field solves the problems that when pressure measurement is conducted on an existing gas field in winter, due to the fact that low-temperature condensate liquid is prone to freezing when entering a pressure measuring instrument, testing is inaccurate, and the pressure measuring instrument is damaged. 本实用新型公开了一种气田用防冻测压装置，包括：外壳；内体，所述内体设置有所述外壳内，所述外壳与所述内体之间填充有防冻液；压力测量仪表，所述压力测量仪表的接收端插入所述内体中；活塞，所述活塞设置在所述内体中，活塞的上端与内体的顶部之间填充有防冻液
