The technical solution that adopts is so for achieving the above object: the waterproof that is provided, the oil-filled type compressed natural gas of antidetonation tensimeter comprise a watchcase that has the watchcase dish, on the watchcase dish, be provided with pointer by the pointer central shaft, in watchcase, be filled with silicone oil and be installed with the Denso wiring board, bottom at watchcase is equipped with the main body joint by rubber seal, is equipped with seal assembly at the Denso wiring board fairlead place of watchcase outer end.
In above-mentioned waterproof, the oil-filled type compressed natural gas of antidetonation tensimeter structure, the main body joint is that circular hole combines with the watchcase bottom, the two adopts the interference fit compression fit together by rubber seal, 30 degree positions, the left and right sides disposed seal assembly on the left of the watchcase outer lower end was positioned at main body simultaneously, the exquisite lead-in wire with the Denso wiring board is drawn and the sealing wire end, isolated table internal and external environment.It is tight isolated that the assembling of this structure can make tensimeter internal environment and external environment condition accomplish, stopped tensimeter water inlet and oil leakage phenomenon effectively.
Technical solution of the present utility model also comprises: by waiting circular arc to be arranged at intervals with four photoelectric receiving tubes and a photoemission cell, being provided with between photoelectric receiving tube and photoemission cell can be with the shadow shield of pointer central shaft rotation on the Denso wiring board.
Technical solution of the present utility model also comprises: the seal assembly of watchcase outer end assembling by band in through hole the watchcase link, be arranged in the watchcase link O RunddichtringO in the through hole and pressure and put in the band at watchcase link rear portion the seal member that compresses of through hole and form, the Denso wiring board fairlead place welded seal of watchcase link and watchcase outer end, the Denso lead is drawn from watchcase link nose end and O RunddichtringO and by compressing the seal member endoporus, carries out butt-end packing locking by compressing seal member.
In the real work, tensimeter main body joint is connected in the interface of compressed natural gas, when operate as normal has gaseous tension, the pointer central shaft drives pointer generation corresponding deflection indicating gauge dial scale and shows the relevant pressure value, shadow shield on the wiring board of pointer central shaft drive simultaneously goes out the stepped appearance simulating signal by the photoelectricity coupled transfer, converting the corresponding electric signal force value to for the transmission of display end corresponding instrument.
Compared with prior art, of the present utility model simple in structure, cost is low, proofread and correct, easy to assembly, stable output signal, waterproof and anti-seismic performance are good, antijamming capability is strong, long service life, its physical construction can effectively be stopped tensimeter water inlet phenomenon, Denso is partly by photoelectricity coupled transfer signal simultaneously, the fluctuation of input signal changes not influence of output signal, stable output signal, effectively promoted the antijamming capability of system, be filled with the anti-seismic performance that silicone oil has also promoted table greatly simultaneously in the table, when vibration frequency and amplitude are all relatively large, still can guarantee the high precision shown and stable output signal, thereby it is the high novel product of a cost performance, its product has remedied the manometric blank of present this area antidetonation type CNG, has started waterproof, the manometric beginning of the oil-filled type compressed natural gas of antidetonation.
