Abstract
The utility model provides an intelligent pressure transmitter, including shell, entrance pressure head, core and diaphragm, shell and entrance pressure head pass through the vice connection of screw thread, the core sets up in the cavity that entrance pressure head and shell formed, the one end of diaphragm and the end face contaction of core, still including setting up the buffer in the mounting hole of entrance pressure head, buffer includes two and mounting hole complex buffer board and sets up the ball between two buffer boards, a plurality of holes of permeating water have evenly been seted up on the buffer board, the diameter of ball slightly is less than the internal diameter of mounting hole. The utility model discloses in, buffer board among the buffer has certain restriction section to the flow of medium, can play the effect that once blocks to the impact of medium, and the ball plays the secondary to the impact of medium and blocks the effect, is consequently starting or stopping constantly can reducing substantially the impact force of medium to the diaphragm.
Description
Technical field
This utility model belongs to flowrate measuring tool technical field, more particularly, to a kind of intelligent pressure transmitter.
Background technology
Pressure transmitter refers to be output as the pressure transducer of standard signal, is that one kind accepts pressure variations and turns in proportion
It is changed to the instrument of standard output signals.The diaphragm of general pressure transmitter does not have protection device, is starting or stoping the moment, empty
The medium such as gas and water or oil is big to the instant impact of diaphragm, easily causes diaphragm to damage.
Utility model content
The purpose of this utility model is for the above-mentioned problems in the prior art, provides one kind can effectively alleviate Jie
The intelligent pressure transmitter of the impulsive force of confrontation diaphragm.
This utility model solves its technical problem and be employed technical scheme comprise that：
A kind of intelligent pressure transmitter, including shell, enters pressure head, core body and diaphragm, and described shell passes through spiral shell with entering pressure head
Stricture of vagina is secondary to be connected, and described core body is arranged in the cavity being formed with shell into pressure head, and one end of described diaphragm is connect with the end face of core body
Touch, also include being arranged at the buffer unit of the installations in the hole into pressure head, described buffer unit include two with installing hole coordinate
Buffer board and the ball being arranged between two buffer boards, described buffer board uniformly offers some permeable holes, described ball
Diameter be slightly less than the internal diameter of installing hole.
Further, described ball offers some through holes.
Further, described enter pressure head outside be provided with chuck, described chuck top and bottom are respectively equipped with outlet and entering
The mouth of a river.
Compared with prior art, the beneficial effect of this utility model generation is：
In this utility model, the buffer board in buffer unit has certain limitations effect to the flowing of medium, can be to medium
Impact play a barrier effect, ball plays secondary barrier effect to the impact of medium, is therefore starting or stoping the moment
Medium impulsive force to diaphragm can be greatly reduced.
Brief description
Below in conjunction with the accompanying drawings this utility model is further illustrated：
Fig. 1 is overall structure diagram of the present utility model；
Fig. 2 is the structural representation of buffer board.
Wherein：1. shell, 2. enters pressure head, 3. core body, 4. diaphragm, 5. installing hole, 6. buffer board, 7. permeable hole, 8. ball,
9. chuck, 10. outlet, 11. water inlets.
Specific embodiment
With reference to embodiment, this utility model is described further：
As shown in Figure 1-2, the intelligent pressure transmitter that this utility model provides, including shell 1, enters pressure head 2, core body 3 and
Diaphragm 4, described shell 1 and enter pressure head 2 and connect by screw thread pair, described core body 3 is arranged at the sky into pressure head 2 and shell 1 formation
Intracavity, one end of described diaphragm 4 and the end contact of core body 3, also include being arranged at into the buffering dress in the installing hole 5 of pressure head 2
Put, described buffer unit include two and installing hole 5 cooperation buffer board 6 and the ball 8 being arranged between two buffer boards 6,
Some permeable holes 7 are uniformly offered on described buffer board 6, the diameter of described ball 8 is slightly less than the internal diameter of installing hole 5.
Some through holes are offered on described ball 8.
Described enter pressure head 2 outside be provided with chuck 9, described chuck 9 top and bottom are respectively equipped with outlet 10 and water inlet
11.
Intelligent pressure transmitter of the present utility model, the buffer board 6 in buffer unit has certain limitations to the flowing of medium
Effect, can play a barrier effect, ball 8 plays secondary barrier effect to the impact of medium, therefore to the impact of medium
Medium impulsive force to diaphragm can be greatly reduced starting or stoping the moment.
It has been described in detail to of the present utility model above by embodiment, but described content is only of the present utility model
Preferred embodiment is it is impossible to be considered for limiting practical range of the present utility model.All made according to this utility model application range
Impartial change and improvement etc., all should still belong within patent covering scope of the present utility model.
Claims (3)
