The piston type pressure sensor comprises a piston jacket and a piston, a union joint and an induction needle, a piston sleeves one end inside the piston jacket in a sealing manner, the other end inside the piston jacket is connected with a gland in a sealing manner, the gland comprises an inner cavity, one end of the gland, which is close to an inner side, is provided with a through hole, thereby enabling the piston jacket and the gland inner cavity to be communicated, an outer end of the gland inner cavity is equipped with an induction needle outer body in a sealing manner, an inner part of the induction needle outer body is sleeved by the induction needle, one side inside the inner cavity of the gland, which is close to the through hole, is sleeved by a filter element, and a spring is connected between the filter element and an end face of the induction needle outer body. According to the piston type pressure sensor, a piston outer body is connected with the induction needle outer body through the gland, the overall structure is compact, and the sealing performance is good. The piston is used as a direct stressed member, gas or liquid inside an inner cavity of the piston outer body is used as a force transfer medium, through transition by the filter element and the spring, force transfer is performed on the induction needle, thus internal precise parts are prevented from being polluted by the outside world, the practical precision and the service life are improved, and the piston type pressure sensor is suitable for places of high temperature, high pressure, corrosion, electromagnetism and the like.
Description
Technical field
The utility model relates to petroleum pipe line pressure sensor technique field, is specifically related to a kind of piston type pressure sensor.
Background technology
At present, pressure transducer weight is various, for the local measurement such as such as oil gas tank, Oil/gas Well, Oil/Gas Pipe, there is unsafe factor in common electrical sensor, under the interference of down-hole rugged environment such as high temperature, high pressure, burn into electromagnetism etc., cannot normally work.
Utility model content
The utility model provides for problems of the prior art and deficiency, provides a kind of machinery and electronics to seal mutually the piston type pressure sensor of combination.
The technical scheme in the invention for solving the technical problem is: a kind of piston type pressure sensor, comprise piston jacket and piston, union joint and inductive needle, piston seal is set in one end of piston jacket inside, the other end of piston jacket inside is sealedly connected with a gland, described gland comprises inner chamber, the inner one end of gland is provided with through hole, thereby piston jacket is communicated with gland inner chamber, in the outer end of gland inner chamber, be sealed and installed with inductive needle ectosome, in described inductive needle ectosome, be set with inductive needle, in described gland inner chamber, near through hole one side, be set with filter core, between filter core and inductive needle ectosome end face, be connected with spring.
In the threeway that has been threaded of the other end of described inductive needle ectosome, three joints of threeway are all mutually vertical; Except the joint being connected with inductive needle ectosome, on two other joint of threeway, be provided with the nut for connecting or sealing.
Position, junction at described threeway and inductive needle ectosome is set with the silk braid to inductive needle end face tightening.
On the sidewall of described piston jacket, be provided with single current and export and be provided with ball-and-seat, helmet is installed on ball-and-seat.
The outside of described filter core is set with filter element spring.
Beneficial effect: the utility model is connected with inductive needle ectosome, compact overall structure, good airproof performance by gland on piston ectosome.Utilize piston as direct stressed member, utilize gas in the outer intracoelomic cavity of piston or liquid as power transmission medium, by filter core and spring as transition, inductive needle is carried out to power transmission, can prevent that inner precise part from receiving outside contamination, improve practical precision and serviceable life, be suitable for the places such as high temperature, high pressure, burn into electromagnetism.
