Description
Technical field
This utility model relates to a kind of manometric sensor and circuit board fixing device.
Background technology
In oil and gas exploitation process, pressure bomb can measure the numerical value of multiple physical quantitys of down-hole, the pressure and temperature value of such as down-hole, downhole in reservoir situation of change and underground equipment operating mode can be judged better according to these measured values, so that it is determined that reasonably exploitation system and inspection pump measure, the exploitation of petroleum gas is had very important significance.
The fixing difficulty of existing manometric sensor, inconvenience installed by circuit board, and the production cycle is long, and production efficiency is low, and manufacturing cost is higher, greatly reduces the reliability of piezometer work.
Summary of the invention
The purpose of this utility model is in that, it is provided that a kind of manometric sensor being prone to carry out installing and circuit board fixing device.
This utility model adopts the following technical scheme that
Manometric sensor and circuit board fixing device, including circuit installing plate, also include sensor and housing is installed, housing installed by this sensor is sleeve-shaped, the first end of circuit installing plate is fixed on sensor and installs one end of housing, is provided with sealing ring fitting recess on the outer circumference surface that housing installed by sensor.
Preferably, described circuit installing plate is provided with installing hole, and the first end of circuit installing plate is provided with boss.
Preferably, circuit installing plate first end is provided with recess.
Preferably, described recess is curved.
Preferably, described sensor is installed the endoporus of housing and is from one end to the other side made up of the first hole section, the second hole section, the 3rd hole section, the 4th hole section, the 5th hole section, and the aperture of the first hole Duan Zhi tetra-hole section increases successively.
Preferably, at least it is provided with chamfering at the step place of the 3rd hole section and the 4th hole section.
Preferably, at sensor, housing is installed and is provided with spanner clamping part.
The beneficial effects of the utility model are, this New device structures is simple, compact and reasonable, and easy to assembly fast connection is reliable, good airproof performance, saves the production time, improves production efficiency, it is easy to uses and promote.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of structural representation of the present utility model.
Fig. 2 is the top view of Fig. 1;
In accompanying drawing, 1 be installing plate, 11 be installing hole, 12 be boss, 13 for recess;
2 it is that the second hole section installed housing, 20a to be the first hole section, 20b be by sensor, 20c is the 3rd hole section, 20d is the 4th hole section, 20e is the 5th hole section, 21 is the first sealing ring fitting recess, 22 is the second sealing ring fitting recess, 23 is spanner clamping part, 24 is chamfering, 25 is chamfering, 26 is cannelure.
Detailed description of the invention
Below in conjunction with accompanying drawing, this utility model is described further.
As it is shown in figure 1, manometric sensor of the present utility model and circuit board fixing device, including circuit installing plate 1, described circuit installing plate 1 is provided with installing hole 11, the first end of circuit installing plate 1 is provided with boss 12, and boss 12 is two, respectively close to two sides of first end. Circuit installing plate 1 first end is provided with recess 13, and described recess 13 is curved. With circuit installing plate 1 in mounting circuit boards, when specifically installing, circuit board is placed on circuit installing plate 1, is threadeded with installing hole (screw can also be used to install with nut) by screw, thus circuit board is fixed on circuit installing plate 1.
Also include sensor and housing 2 is installed, this sensor installs housing 2 in sleeve-shaped, the endoporus of housing 2 installed by sensor is the cavity installing sensor, the first end of circuit installing plate 1 is fixed on sensor and installs one end of housing, circuit installing plate 1 and housing 2 be cut by line integrated, owing to boss 12 is two, therefore, circuit installing plate 1 is arranged in great-leap-forward on sensor installation housing 2. Being provided with sealing ring fitting recess on the outer circumference surface that housing 2 installed by sensor, sealing ring fitting recess is two, respectively the first sealing ring fitting recess 21 and the second sealing ring fitting recess 22. Described sensor is installed the endoporus of housing 2 and is from one end to the other side made up of the first hole section 20a, the second hole section 20b, the 3rd hole section 20c, the 4th hole section 20d, the 5th hole section 20e, the aperture of the first hole section 20a to the 4th hole section 20d increases successively, therefore, between adjacent two hole sections, define step, and be at least respectively equipped with chamfering 24,25 at the step place of the 3rd hole section and the 4th hole section. The wall of the 5th hole section 20e is provided with cannelure 26, first sealing ring fitting recess 21 and the second sealing ring fitting recess 22 correspond to the first hole section 20a, additionally, installing housing 2 at sensor and be provided with spanner clamping part 23, this spanner clamping part 23 correspond to a part of the 3rd hole section 20c and the four hole section 20d.
