Detailed description of the invention
This detailed description of the invention provides a kind of intelligent positioner with gasket seal, and it can be by pressureThe gas that electricity valve is discharged exports to the outside of intelligent positioner, the impurity pair of having avoided gas to containThe adverse effect of intelligent positioner.
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is enteredRow is described clearly and completely, and obviously, described embodiment is only that the present invention's part is implementedExample, instead of whole embodiment. Based on the embodiment in the present invention, ordinary skill peopleMember, not making the every other embodiment obtaining under creative work prerequisite, belongs to thisThe scope of bright protection.
Please refer to Fig. 1-Fig. 8, a kind of intelligence location with gasket seal that this detailed description of the invention providesDevice, comprise piezo electric valve 11, be arranged at piezo electric valve 11 1 sides piezoelectricity valve gap 12, be arranged at piezo electric valve 11The piezo electric valve main body 13 of opposite side and be arranged at the gas path module 14 of piezo electric valve main body 13 opposite sides, pressesBetween electricity valve gap 12 and piezo electric valve 11, be provided with rubber cushion 15, rubber cushion 15 is provided with the steam vent with piezo electric valve 11The air slot 16 communicating, when rubber cushion 15 is adjacent to mutually with piezo electric valve 11, air slot 16 and piezo electric valve 11 shapesBecome airtight air guide channel, and rubber cushion 15 is provided with the air guide post 17 communicating with air slot 16, piezo electric valve masterThe pedestal 18 of body 13, gas path module 14 and intelligent positioner is provided with the air guide corresponding with air guide post 17Hole, and be provided with gasket seal 20 between gas path module and piezo electric valve main body.
So arrange, the intelligent positioner that this detailed description of the invention provides, its piezo electric valve 11 passes through steam ventThe gas of discharging, can be discharged by the air slot 16 that is arranged at rubber cushion 15, because rubber cushion 15 is adjacent at piezoelectricityOn valve 11 time, air slot 16 can form airtight air guide channel with piezo electric valve 11, can avoid gas looseEnter other position to intelligent positioner, and gas can be by being arranged at air guide post 17 Hes of rubber cushion 15The gas port that is arranged at piezo electric valve main body 13, gas path module 14 and pedestal 18 is discharged; In addition, due to gasBetween road module 14 and piezo electric valve main body 13, be provided with gasket seal 20, gasket seal 20 can be by gas circuitBetween module and piezo electric valve main body, seal reliably, prevent that gas is by gas path module and piezo electric valve main bodyBetween gap infiltrate other position of intelligent positioner.
Therefore, the intelligent positioner that this detailed description of the invention provides, can prevent the gas that piezo electric valve 11 is dischargedBody remains in the inside of intelligent positioner, has avoided the pollution of the impurity in gas to intelligent positioner.
It should be noted that the intelligent positioner that this detailed description of the invention provides, the air guide that rubber cushion 15 arrangesPost 17 can run through the pedestal 18 of piezo electric valve main body 13, gas path module 14 and intelligent positioner successively, withGas is expelled to the outside of intelligent positioner.
For the ease of installing, the air guide post 17 that rubber cushion 15 arranges can only be inserted into piezo electric valve main body 13In, piezo electric valve main body 13, gas path module 14 and pedestal 18 can be provided with corresponding with air guide post 17Gas port, gas enters in gas port by air guide post 17, then exports to the outside of intelligent positioner.
So arrange, can shorten the length of air guide post 17, when assembling intelligent positioner, have preferablyOperability.
In order to prevent that gas from entering intelligent positioner by the gap between piezo electric valve 11 and piezo electric valve main body 13Inside, in the preferred version of this detailed description of the invention, can between piezo electric valve 11 and piezo electric valve main body 13To be provided with seal membrane 19, seal membrane 19 is provided with the gas port passing for air guide post 17.
So arrange, will between piezo electric valve 11 and piezo electric valve main body 13, seal by seal membrane 19,Can prevent that gas from spilling into its of intelligent positioner by the gap between piezo electric valve 11 and piezo electric valve main body 13Its position, and then further avoided the pollution of gas to intelligent positioner.
In addition, for the extraneous air that prevents intelligent positioner enters intelligence by the through hole that is arranged at pedestal 18Can locator inside.
As preferably, the through hole of pedestal 18 can be provided with one-way exhaust valve 21, by this one-way exhaust valve21 piezo electric valves 11 can be expelled to gas the outside of intelligent positioner, but intelligent positioner outsideAir but can not enter intelligent positioner inside.
As preferably and for example, the air slot 16 that is arranged at rubber cushion 15 can comprise many with piezo electric valve 11The groove that individual steam vent communicates respectively, and the dry groove that multiple grooves are connected, air guide post 17 and dry groove phaseBe communicated with.
The gas that the steam vent of more than 11 position of piezo electric valve is discharged can come together in dry groove by multiple grooves, andBe expelled to afterwards the outside of intelligent positioner by air guide post 17. The rubber cushion 15 so arranging simple in structure,Be easy to processing.
In addition, in order to improve the installability of rubber cushion 15 and piezo electric valve 11, air guide post 17 can be arranged atAn edge of rubber cushion 15, another edge of rubber cushion 15 can be provided with screens post 22, piezo electric valve 11Be provided with the unfilled corner 23 corresponding with air guide post 17 and screens post 22 difference, piezo electric valve 11 is by unfilled corner 23Be placed between air guide post 17 and screens post 22.
So arrange, the air guide post 17 that is arranged at rubber cushion 15 can also have the function of screens post 22 simultaneously,By the holding effect of air guide post 17 and screens post 22, rubber cushion 15 can connect with piezo electric valve 11 reliablyBe connected together.
It should be noted that, the rubber cushion 15 that this detailed description of the invention provides can be silicagel pad, certainly, and alsoCan be rubber blanket etc., only need it to there is good sealing.
To the above-mentioned explanation of the disclosed embodiments, professional and technical personnel in the field can be realized orUse the present invention. The multiple amendment of these embodiment for those skilled in the art willApparent, General Principle as defined herein can do not depart from spirit of the present invention orIn the situation of scope, realize in other embodiments.
