Abstract
The utility model relates to a manometer field discloses an isolating device for manometer, including upper cover (1), lower cover (2) and diaphragm (3), upper cover (1) escape (5) that internal thread (4) be connected with the manometer and processing internal thread (4) formed have, upper cover (1) and lower cover (2) seal to connect as an organic whole, the inside cavity that forms, pressing from both sides all around of diaphragm (3) is established between cavity interior upper cover (1) and lower cover (2), be equipped with around diaphragm (3) and between lower cover (2) sealing washer (6), escape (5) locate to be equipped with air -out through hole (7), the diameter of air -out through hole (7) is 1.0 1.5mm, upper cover (1) and lower cover (2) through threaded connection as an organic whole. This isolating device can get rid of to fall the air in the cavity between isolating device and the manometer through air -out through hole at the in -process with manometer equipment, avoided ressure measurement to be bullied the condition that the visionary hope makes a sound.
Description
Technical field
The utility model relates to Pressure gauge field, particularly relates to the isolating device of diaphragm.
Background technology
Diaphragm forms after being added isolating device by universal Pressure gauge, and it is applicable to measure deep-etching, high temperature, high viscosity, easily crystallize, easily solidify, have the pressure medium of solid floating material and must avoid measuring the medium universal Pressure gauge of entrance and preventing sediment accumulation and the occasion of easy cleaning.In described universal Pressure gauge, filling has silicone oil, is provided with diaphragm in isolating device, and this diaphragm both can avoid measured medium to enter Pressure gauge, the elastic deformation of self can be utilized in the pressure transmission of measured medium to Pressure gauge again, indirectly measure pressure.Diaphragm is when assembling, silicone oil is refilled after first being vacuumized by Pressure gauge, then it is loaded on upper cover and fills the isolating device of silicone oil equally, can be affected by bubble without air, the pressure that otherwise barrier film transmits in must assure that the cavity of Pressure gauge and isolating device after being completed and be caused measuring inaccurate.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of Pressure gauge isolating device, with ensure isolating device after being assembled on Pressure gauge, and without air in the cavity between Pressure gauge.
The utility model solves its technical problem the technical scheme is that Pressure gauge isolating device, including upper cover, lower cover and diaphragm, described upper cover has the internal thread being connected with Pressure gauge and the escape of machining internal thread formation, described upper cover and lower cover are closed and are connected as one, it is internally formed cavity, the surrounding of described diaphragm is folded in described cavity between upper cover and lower cover, it is provided with sealing ring between surrounding and the lower cover of described diaphragm, it is provided with exhaust hole at described escape, a diameter of 1.0-1.5mm of exhaust hole, described upper cover and lower cover are threaded connection and are integrated, the threaded installation facilitated between upper cover and lower cover, dismounting.
The surface of described diaphragm is provided with the asperities of multi-layer annular, and asperities can preferably play the effect of pressure transmission, and is easier to after a measurement recover elastic deformation.
When loading onto isolating device, seal need to be added between Pressure gauge and isolating device, to ensure the sealing effectiveness of junction.Owing to exhaust hole designs at escape, therefore screw isolating device with manometric during, air in cavity between the two and unnecessary silicone oil can be discharged by exhaust hole, after screwing completely, being sealed by above-mentioned seal between Pressure gauge and isolating device, exhaust hole will no longer function.
The beneficial effects of the utility model are: when screwing isolating device and Pressure gauge, exhaust hole can be utilized the air in cavity and unnecessary silicone oil to be discharged, it is to avoid owing to there is air in cavity, cause the inaccurate phenomenon of gauge measurement value.Further, since exhaust hole is arranged at the escape of upper cover internal thread, therefore comparing on the screw thread being arranged on internal thread, it can discharge air as much as possible and unnecessary silicone oil in screwing operations.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the schematic diagram after the utility model assembles with Pressure gauge;
Figure is labeled as: 1-upper cover, 2-lower cover, 3-diaphragm, 4-internal thread, 5-escape, 6-sealing ring, 7-exhaust hole.
Detailed description of the invention
Below in conjunction with specific embodiment, the utility model is described in further detail, but embodiment of the present utility model is not limited to this.
As it is shown in figure 1, Pressure gauge isolating device of the present utility model, including upper cover 1, lower cover 2 and diaphragm 3.Described upper cover 1 has the internal thread 4 being connected with Pressure gauge and the escape 5 of machining internal thread 4 formation, is provided with exhaust hole 7, a diameter of 1.2mm of exhaust hole 7 at escape 5.Described upper cover 1 and lower cover 2 are closed and are connected as one, and are internally formed cavity, and the surrounding of described diaphragm 3 is folded in described cavity between upper cover 1 and lower cover 2, is provided with sealing ring 6 between surrounding and the lower cover 2 of diaphragm 3.Described upper cover 1 and lower cover 2 are threaded connection and are integrated.The surface of described diaphragm 3 is provided with the asperities of multi-layer annular.
Before Pressure gauge is loaded onto isolating device of the present utility model, seal need to be added between, to ensure the sealing effectiveness of junction.Owing to exhaust hole designs at escape, therefore screw isolating device with manometric during, air in cavity between the two and unnecessary silicone oil can be discharged by exhaust hole, after screwing completely, sealed by above-mentioned seal between Pressure gauge and isolating device, exhaust hole will no longer function, as in figure 2 it is shown, the schematic diagram after assembling for isolating device and Pressure gauge.
Claims (2)
1. Pressure gauge isolating device, including upper cover (1), lower cover (2) and diaphragm (3), the escape (5) that described upper cover (1) has an internal thread (4) being connected with Pressure gauge and machining internal thread (4) is formed, described upper cover (1) and lower cover (2) are closed and are connected as one, it is internally formed cavity, the surrounding of described diaphragm (3) is folded in described cavity between upper cover (1) and lower cover (2), it is characterized in that: between surrounding and the lower cover (2) of described diaphragm (3), be provided with sealing ring (6), described escape (5) place is provided with exhaust hole (7), a diameter of 1.0-1.5mm of exhaust hole (7), described upper cover (1) and lower cover (2) are threaded connection and are integrated.
