Abstract
The utility model provides a sealing connection of a common rail device, which comprises a connecting end of the common rail device, wherein an adapter is connected inside the connecting end, a pressure sensor is connected inside the adapter, a through hole is formed inside the adapter, pressure is conducted through the through hole and is transmitted to the pressure sensor, the pressure sensor can monitor the internal pressure of the common rail device conveniently, and the pressure sensor can be conveniently disassembled and assembled, so that the sealing connection of the common rail device and the pressure sensor is realized.
Description
Technical Field
The utility model mainly relates to the technical field of common rail devices, in particular to sealing connection of common rail devices.
Background
The high-pressure common rail electric injection technology refers to an oil supply mode which completely separates the generation of injection pressure and the injection process from each other in a closed-loop system consisting of a high-pressure oil pump, a pressure sensor and an electronic control unit. The high-pressure fuel oil is delivered to the public fuel oil supply pipe by the high-pressure oil pump, and the oil pressure in the public fuel oil supply pipe is accurately controlled, so that the pressure of the high-pressure fuel oil pipe is irrelevant to the rotating speed of the engine, and the degree of the change of the fuel supply pressure of the diesel engine along with the rotating speed of the engine can be greatly reduced.
A pressure sensor is typically mounted at one end of the common rail for monitoring the internal pressure of the common rail. The inner cavity of the common rail device is used as an oil storage tank, so the inner hole of the common rail device is generally more than 8 mm. The hole of most common rail wares is 15mm, but the biggest excircle diameter of pressure sensor's sealed conical surface is general all less, generally below 8mm, therefore can't directly install pressure sensor on the common rail ware, the dismouting of being not convenient for and monitoring.
SUMMERY OF THE UTILITY MODEL
The utility model mainly provides a sealing connection of a common rail device, which is used for solving the technical problems in the background technology.
The technical scheme adopted by the utility model for solving the technical problems is as follows:
the utility model provides a sealing connection who shares rail ware, wherein, includes the link that shares rail ware altogether, the internal connection of link has the adapter, the adapter in-connection has pressure sensor, open the inside of adapter has the through-hole, realizes the conduction of pressure through the through-hole, conducts pressure for pressure sensor.
Further, the inboard of link and the top of adapter adopt the sphere to be connected with the sealed mode of the conical surface, adopt the form of bipyramid face to carry out sealing connection between the rear end of through-hole and pressure sensor's the top, the inside wall of link passes through screw thread locking with the lateral wall of adapter, the inside wall of adapter passes through screw thread locking with pressure sensor's lateral wall.
Furthermore, the diameter of the through hole is 1.5-3 mm.
Compared with the prior art, the utility model has the beneficial effects that:
the utility model provides a sealing connection who shares rail ware, sets up link, the adapter that shares rail ware, realizes pressure conduction through the inside through-hole of adapter, makes things convenient for pressure sensing monitoring to share rail ware's internal pressure, also makes things convenient for pressure sensor's dismouting to realize sharing rail ware and pressure sensor's sealing connection.
The present invention will be explained in detail below with reference to the drawings and specific embodiments.
