Description
Technical field
The utility model relates to tensimeter protective device, is specifically related to a kind ofly to ensure the pressure watchcase that in watchcase, tensimeter normally works under the bad working environments of deep sea low temperature high pressure.
Background technology
The jumper pipe that recoverable claw connector is applied between deepwater field manifold connects, and it is operated in the deep-sea of 1500 meters, environments such as subsea extreme.In order to complete claw connector predetermined action under water, needing various tensimeter to monitor in real time claw connector internal hydraulic pressure parameter, using comparatively frequent and requiring that control accuracy is higher.Under working environment, watchcase needs the pressure bearing about 15Mpa, and corrosive properly is stronger.
Common indicator type tensimeter, be not with long-range transmission display, regulatory function, and the element of tensimeter inside is more responsive, very easily damages under the condition of subsea cryogenic, high pressure, deep-etching.If it directly cruelly leaked at working environment, tensimeter cannot normally work, and even can cause irreversible badly damaged.
Utility model content
The utility model provides pressure watchcase, solves the problem that the tensimeter that exists in prior art cannot use under the operating mode of deep sea low temperature high pressure.
For solving the problem, the utility model adopts following technical scheme: pressure watchcase, is made up of housing, joint, glass gland, plastic spacer and withstand voltage glass, and housing is columnar structured; Tensimeter is provided with in housing; Joint is cylindrical structural, and the center is provided with through hole, and joint right-hand member center is provided with groove, and described through hole and groove connect; Joint right-hand member is provided with circular chuck; Be provided with opening on the left of housing, joint is arranged in described opening, and the chuck on joint is positioned at enclosure interior; Chuck on joint and body contact place are provided with O-ring seal II; Manometric left end is arranged in the groove on joint; Bottom portion of groove junction on manometric left end and joint is provided with combination sealing packing ring; Joint left end reaches outside; Joint is fixed on housing by hexagonal nut by the part of joint outside housing; Be hatch frame on the right side of housing, its opening part is provided with groove, is disposed with withstand voltage glass and glass gland in described groove from left to right; Plastic spacer is provided with between withstand voltage glass and glass gland; Withstand voltage glass and body contact place are provided with O-ring seal I.
Advantage of the present utility model has: the utility model adopts ultra-low carbon austenitic stainless steel to be the housing of material, has good anticorrosive property; The utility model entirety adopts hermetically-sealed construction, ensure that the working pressure of tensimeter in housing; Further, the utility model is designed with glass sunroof, can observe manometric state, is convenient to maintenance and changes tensimeter original paper.Tensimeter of the present utility model can use under the operating mode of deep sea low temperature high pressure, guarantees sealing during use, and uses under being adapted at hyperbaric environment.

Embodiment
By best embodiment, the utility model is described in detail below
.
As Figure 1-4, pressure watchcase, is made up of housing 1, joint 2, glass gland 3, plastic spacer 4 and withstand voltage glass 5, and housing 1 is columnar structured; The material of housing is ultra-low carbon austenitic stainless steel (00Cr17Ni14Mo2), has that welding performance is good, postwelding is without knife line corrosion tendency, all have the advantages such as good corrosion stability to sulphurous acid, sulfuric acid, phosphoric acid, acetic acid, formic acid, villaumite, halogen, sulphite.Tensimeter 7 is provided with in housing 1; Joint 2 is cylindrical structural, and the center is provided with through hole, and joint 2 right-hand member center is provided with groove, and described through hole and groove connect; Joint 2 right-hand member is provided with circular chuck; Circular chuck is along the circumferential direction annular bulge-structure at joint 2 right-hand member; Tensimeter 7 can be connected with outside by joint, and transmits data.
Be provided with opening on the left of housing 1, joint 2 is arranged in described opening, and it is inner that the chuck on joint 2 is positioned at housing 1; Chuck on joint 2 and housing 1 contact position are provided with O-ring seal II8; The left end of tensimeter 7 is arranged in the groove on joint 2; Bottom portion of groove junction on the left end of tensimeter 7 and joint 2 is provided with combination sealing packing ring 9; It is outside that joint 2 left end reaches housing 1; Joint 2 is fixed on housing 1 by hexagonal nut 10 by the part of joint 2 outside housing 1;
Be hatch frame on the right side of housing 1, its opening part is provided with groove, is disposed with withstand voltage glass 5 and glass gland 3 in described groove from left to right; Plastic spacer 4 is provided with between withstand voltage glass 5 and glass gland 3; Withstand voltage glass 5 is provided with O-ring seal I6 with housing 1 contact position.Withstand voltage glass 5 and glass gland 3 are transparent configuration, can observe directly manometric situation in pressure watchcase.
O-ring seal I6, O-ring seal II8 that junction of the present utility model adopts and combination sealing packing ring 9 are to ensure the sealed environment after assembling, not allowed leakage, thus ensure the working environment of internal pressure table.
Last it is noted that obviously, above-described embodiment is only for the utility model example is clearly described, and the restriction not to embodiment.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here exhaustive without the need to also giving all embodiments.And thus the apparent change of amplifying out or variation be still among protection domain of the present utility model.
