Technical Field
The utility model relates to the field of container vacuum degree measurement technology, in particular to a shell protective sleeve for a vacuum degree gauge pipe.
Background
The vacuum gauge is a sensor for measuring the vacuum. The principle is as follows: and transmitting the electric signal measured by the vacuum gauge to a vacuum degree measuring instrument, and displaying the vacuum degree value of the vacuum environment after amplification processing and signal processing. The vacuum gauge is mainly applied to the field of vacuum degree measurement in a vacuum environment.
The vacuum degree of a low-temperature vacuum heat-insulating container is an important pressure container, and the vacuum degree directly affects the heat insulation condition of the container, so that the measurement of the vacuum degree is particularly necessary at regular intervals. The low-temperature vacuum heat-insulation container is generally installed outdoors, is easily corroded by rainwater and the like, easily causes corrosion damage to a gauge pipe installed below the container, and further influences the accuracy of detection numerical values.
At present, the conventional vacuum gauge protection mainly adopts a plastic shell to be fixed through bolts, the sealing performance of the inner part and the outer part of the shell cannot be ensured by the fixing method, and rainwater often easily enters the plastic shell through gaps. When the vacuum degree is actually measured, the bolt needs to be unscrewed, and after opening and closing for a plurality of times, the tightness of connection between the bolt and the plastic shell is also reduced.

The purpose of the utility model is: the utility model provides a vacuum gauge pipe shell protective sheath under can adapting to rain water environment to the in-service use demand of protective sheath has been considered, has designed and has opened the structure fast, can make things convenient for the efficient to measure the container vacuum.
In order to achieve the purpose, the technical scheme of the utility model provides a vacuum gauge pipe shell protective sleeve which comprises a first outer protective sleeve fixedly arranged on a low-temperature vacuum heat-insulation container, a second outer protective sleeve arranged at the lower end of the first outer protective sleeve, and a locking device detachably connected with the first outer protective sleeve and the second outer protective sleeve, wherein the first outer protective sleeve and the second outer protective sleeve are downward in the axial direction and sleeved with a gauge pipe fixed at the lower end of the low-temperature vacuum heat-insulation container.
Preferably, the locking device comprises a locking hook fixedly arranged on the first outer protective sleeve and a locking buckle rotatably connected to the second outer protective sleeve, and the locking hook and the locking buckle are matched with each other.
Preferably, the locking buckle is provided with two connecting points, and the connecting points rotate through a hinge.
Preferably, the first outer protective sleeve and the second outer protective sleeve are connected in an inner and outer socket manner.
Preferably, the upper end of the second outer protective sheath is inserted inside the lower end of the first outer protective sheath.
Preferably, the vacuum degree gauge pipe is sleeved and buckled with an inner protective sleeve, and the gauge pipe is connected with the inner protective sleeve in a sealing mode.
Preferably, the first outer protective sheath and the second outer protective sheath are both cylindrical structures.
In summary, the utility model has the following beneficial technical effects:
the gauge pipe can be well protected by the utility model, and the quick opening structure is designed, so that the measurement efficiency is improved.

Detailed Description
The present invention is described in further detail below with reference to FIGS. 1-2.
The embodiment of the utility model discloses a vacuum gauge pipe shell protective sleeve.
Referring to fig. 1 and 2, the valve 3 is welded on the low-temperature vacuum heat-insulating container 1, the gauge tube 4 is in threaded connection with the lower end of the valve 3, and the gauge tube protecting sleeve 2 of the vacuum gauge tube protecting sleeve in the embodiment comprises an inner protecting sleeve 11 buckled outside the gauge tube 4 and an outer protecting sleeve sleeved outside the gauge tube 4.
The inner protective sleeve 11 is tightly attached to the gauge pipe 4 to be connected in a sealing mode, plays a role in protecting the first layer and is mainly made of rubber.
The whole outer casing is a cylindrical structure and consists of a first outer protective casing 5 and a second outer protective casing 10, and the first outer protective casing 5 is close to and welded on the container body 7 so as to ensure the sealing property; the second outer protective sheath 10 sets up in the lower extreme of first outer protective sheath 5, adopts the mode of inside and outside socket joint between the two to after the connector 6 registrates of first outer protective sheath 5 and second outer protective sheath 10, utilize locking device to give connector 6 certain pretightning force, can conveniently dismantle second outer protective sheath 10, and can reach sealed effect. Wherein, the upper end socket of second outer protective sheath 10 is inboard at the lower extreme of first outer protective sheath 5, can further reduce the condition emergence that the rainwater got into inside first outer protective sheath 5 and second outer protective sheath 10.
The locking device consists of a locking hook 8 welded on the first outer protective sheath 5 and a locking buckle 9 rotatably connected on the second outer protective sheath 10. Two connecting points for rotation of the locking buckle 9 are hinges 12, when one end of the locking buckle 9 hooks the locking hook 8, and the other end of the locking buckle is pressed to the bottom, the locking purpose can be realized, and a certain pretightening force is provided for the connecting port 6.
The implementation principle of the embodiment is as follows: when the vacuum degree gauge needs to be measured, the locking device is opened according to the field situation, the locking buckle 9 is separated from the locking hook 8, the second outer protective sleeve 10 is taken down, then the inner protective sleeve 11 is taken down to expose the gauge 4, the vacuum degree detector is connected with the gauge 4, and the vacuum degree data is read. After the detection is finished, the inner protective sleeve 11 and the gauge pipe 4 are sleeved, finally the second outer protective sleeve 10 and the first outer protective sleeve 5 are connected in a socket joint mode, and after the locking device is locked, a measurement task is finished.
