In addition, the pressure sensor and the distributing valve which are used in the prior art are in threaded connection, sealing glue is smeared at the threaded connection part of the distributing valve, the sealing glue is easy to cure, during assembly, the second end of the pressure sensor needs to be screwed into a threaded hole in the distributing valve immediately after the sealing glue is smeared, if the screwing direction of a worker slightly deviates, the pressure sensor and the distributing valve need to be assembled again after being separated, at the moment, the sealing glue is difficult to separate because the sealing glue is cured, and the assembly can be carried out again after the cured sealing glue needs to be cleaned, so that the existing assembly process is inconvenient to operate and low in efficiency.
SUMMERY OF THE UTILITY MODEL
The utility model discloses a distribution valve is with built-in pressure sensor, it has solved among the prior art pressure sensor for distribution valve and has operated inconvenient inefficiency with distribution valve assembly process, and the contact pin is connected not firm technical problem with the core in the casing to can reach and change the simple sealed effectual, the contact pin of joining in marriage the process and be connected firm low-fault-rate technological effect with the core. The utility model discloses the technical scheme who adopts as follows:
the utility model provides a built-in pressure sensor for distributing valve, includes the casing, draws pressure hole, core, contact pin and plug, the plug is located the casing first end and is used for being connected with adjacent spare part, the core is located in the casing, the one end and the core of contact pin are connected, the other end of contact pin stretches out outside the first end of casing, draw the pressure hole and locate the casing second end, just the casing second end is pegged graft fixedly with the distributing valve, the casing second end is sealed with the epoxy of filling of distributing valve grafting fixed department.
On the basis of the technical scheme, an annular groove is arranged at the position close to the second end of the shell, and an O-shaped sealing ring is sleeved outside the annular groove.
On the basis of the technical scheme, the contact pin and the core body are welded and fixed through the solder wire, and epoxy sealant is filled in the shell at the welding position.
On the basis of the technical scheme, the plug and the shell are integrally formed, and the plug is provided with a slotted hole for accommodating the contact pin.
On the basis of the technical scheme, the plug and the shell are both made of insulating plastics.
Advantageous effects
The utility model discloses well pressure sensor adopts the mode of pegging graft with the distributing valve, and grafting department is equipped with annular groove and O type circle, and O type circle can effectively prevent pressure leakage, and the simple easy operation of assembling process, and can in time revise after the misoperation, is favorable to improving product performance. And the splicing part of the pressure sensor and the pressure sensor is filled with epoxy sealant, and the epoxy sealant is filled to enhance the shock resistance, impact resistance and anti-interference performance of the pressure sensor, so that the detection result of the pressure sensor is more accurate while the pressure sensor is protected.
The utility model discloses well contact pin and core pass through tin wire welded fastening, and the casing intussuseption of welding department is filled with the epoxy and is sealed gluey, so can guarantee the higher firm degree of being connected of contact pin and core, reduce short circuit and trouble risk, utilize the epoxy to seal the gluey packing in addition to have the shock resistance, impact resistance and the interference killing feature who utilizes reinforcing pressure sensor itself, make pressure sensor's testing result more accurate when protecting pressure sensor itself.
