Description
Technical field
The utility model is related to a kind of signal transmitter, especially a kind of pressure transmitter.
Background technology
Pressure transmitter is a kind of when hydraulic work system, and the filter core in oil filter is contaminated object blocking, inlet and outlet pressure
Power generates pressure, when pressure value increases to the setting value of signalling generator device, signalling generator one end switch connection signal alarm, and meanwhile it is another
One end mesh shows the pop-up of signalling generator red button to show alarm, and instruction system operators should clean or replace in time filter core, it is ensured that
Hydraulic system normal operation.The basic role of pressure signal transmitter be hydraulic system during the work time, the impurity in fluid is micro-
Grain is stopped by filter core in oil filter, so as to which filter core gradually blocks, generates into fuel-displaced pressure, when pressure value reaches the full quota
When, turn on automatically power supply shows sender signal.But existing pressure transmitter, poor sealing performance, steam are easily accessible instrument
In disk, the rotation of pointer on instrument board is disturbed so that reading is not allowed, and alarm system is also susceptible to problem, influences to use, simultaneously
Steam easily forms water mist in instrument board the cover, influences to observe.

Binding groove is formed between the fastening convex ribs and housing exterior walls, the dial hood cover rim, which is circumferentially provided with, compresses side, the pressure
Pilled-in selvedge is pressed on fastening convex ribs upper surface, and the compression side internal perisporium is connected with panel the cover, and periphery wall is free end, freely
End extends to binding groove and forms sealing of the panel the cover to opening.
The advantageous effect so set is：Using the above program, installation panel the cover, the compression of panel the cover are so set
Side is set by the way of roll-in and forms package to fastening convex ribs so that and the free end for compressing side is pressed in binding groove, so as to
Realize the sealing to shell nozzle so that steam cannot enter wherein, while so that the combination of panel the cover and housing is more tight
It is close, the stability of effective holding structure.
The utility model is further arranged to be provided with pressure detecting mouth on the housing, is installed on the pressure detecting mouth
There is connector, blocked on the pressure detecting mouth and be provided with partition plate, the connector is connected through partition plate with pressure sensitive device,
External screw thread is provided on the connector outer circumferential surface, clamp nut, the clamp nut and company are also arranged on the connector
Joint screw thread will be pressed on partition plate on housing with merging.
The advantageous effect so set is：Using the above program, by being supported in pressure detecting mouth setting partition plate, then by partition plate
It is pressed between clamp nut and housing, the sealing to pressure detecting mouth can be effectively formed so that extraneous dirt cannot be introduced into, and protect
The stabilization of internal structure is demonstrate,proved, extends service life of equipment.
The utility model is further arranged to be additionally provided with closed cell on the connector outer circumferential surface, is set in the closed cell
There is sealing ring.
The advantageous effect so set is：Using the above program, sealing ring is arranged between clamp nut and external equipment,
It is further ensured that sealing, while clamp nut is caused to be not susceptible to rotate, so as to ensure the compression to partition plate.
The utility model is further arranged to the connecting hole and is equipped with connecting wire in the air, and the connecting hole is circumferentially set
It is equipped with sealing ring.
The advantageous effect so set is：Using the above program, sealing ring is set in connection hole, can be effectively formed pair
The sealing of sealing ring so that extraneous dirt cannot be introduced into, and ensure the stabilization of internal structure, extend service life of equipment.
