Description
Technical Field
The utility model relates to a storage device especially relates to a stainless steel vacuum storage device.
Background
Some articles in the laboratory often need to be preserved in vacuum environment, and common evacuation products in the existing market mostly combine dedicated plastics vacuum bag to use, and this kind of method vacuum degree is difficult to reach the requirement on the one hand, and on the other hand because the vacuum degree can't show in the bag, there is the gas leakage risk and can't in time discover to preserve for a long time to fragile article can't play the guard action, finally makes article life-span reduce damage even.
Disclosure of Invention
An object of the utility model is to overcome prior art's not enough, provide a stainless steel vacuum storage device that article and vacuum can be shown is deposited for a long time in suitable laboratory.
The utility model discloses a stainless steel vacuum storage device, which comprises a storage tank, wherein a sealing gasket is arranged on the top wall of the storage tank, a sealing cover consists of an upper disk body and a lower disk body which are coaxially and integrally arranged, the diameter of the lower disk body is smaller than that of the upper disk body, the annular wall of the lower disk body is provided with an external thread, the lower disk body is inserted into the storage tank and is in threaded connection with the inner wall of the top of the storage tank, the upper disk body is covered on the sealing gasket, a fastening bolt is welded in the middle of the sealing cover, a middle hole is arranged between the sealing cover and the fastening bolt, the middle hole is in welded communication with the lower port of a lower clamping sleeve, the upper port of the lower clamping sleeve is communicated with the first port of a three-way joint, the second port of the three-way joint is communicated with the lower port of an upper clamping sleeve, the upper port of the clamping sleeve is communicated with the inlet of a ball valve through, the outlet of the trunnion ball valve is communicated with the inlet of the vacuum pump through a pipeline, the third interface of the three-way joint is communicated with one end of a branch pipe, and the other end of the branch pipe is connected with a pressure gauge.
The utility model has the advantages that:
(1) can reach higher vacuum degree, is convenient for the laboratory to store the articles needing vacuum preservation for a long time;
(2) the pressure inside the device can be read, so that the phenomenon of air leakage can be found in time conveniently;
(3) simple structure, easy operation, stainless steel material intensity is high, and is not fragile, is fit for the fragile object that needs vacuum preservation.
Drawings
FIG. 1 is a front view of a stainless steel vacuum storage unit of the present invention;
fig. 2 is a partially enlarged view of the structure of fig. 1 at the sealing cover of the stainless steel vacuum storage device.
Detailed Description
The present invention will be described in detail with reference to the accompanying drawings and specific examples.
As shown in the attached drawing the utility model discloses a stainless steel vacuum storage device, including the storage jar 5 roof on be provided with seal ring 6, a sealed lid 7 comprises the integrative last disk body that sets up of upper and lower coaxial line and lower disk body, lower disk body diameter be less than last disk body diameter lower disk body rampart on open and to have the external screw thread, lower disk body insert in the storage jar 5 and with storage jar 5 top inner wall threaded connection and go up the disk body lid on seal ring 6. The middle of the sealing cover 7 is welded with a fastening bolt 8, and the fastening bolt can be rotated to play a role in screwing the sealing cover. The middle of the sealing cover 7 and the fastening bolt 8 is provided with a middle hole, the middle hole is communicated with a lower port of a lower clamping sleeve in a welding mode, an upper port of the lower clamping sleeve is communicated with a first port of a three-way joint 9, a second port of the three-way joint 9 is communicated with a lower port of an upper clamping sleeve 3, and an upper port of the upper clamping sleeve 3 is communicated with an inlet of the trunnion ball valve 1 through a clamping sleeve 2. The outlet of the trunnion ball valve 1 is communicated with the inlet of the vacuum pump through a pipeline, the third interface of the three-way joint 9 is communicated with one end of a branch pipe, and the other end of the branch pipe is connected with a pressure gauge 4.
The use method of the device is as follows:
in the actual use process of the vacuum storage device, articles to be stored are placed in the storage tank 5, the storage tank is in threaded connection with the sealing cover, and the sealing cover 7 is driven to be screwed into the storage tank 5 by rotating the fastening bolt 8 and tightly presses the sealing washer 6 placed between the storage tank and the sealing cover; connecting the trunnion ball valve 1 with a vacuum pump, starting the vacuum pump and ensuring that a trunnion ball valve switch is in an open state, discharging air through a middle hole on a sealing cover through a lower clamping sleeve and an upper clamping sleeve at the moment, observing a pressure gauge, and closing the trunnion ball valve when the vacuum degree meets the requirement; the sealed tank can keep high vacuum degree, and when the pressure exceeds the limit value of the stored articles in the storage process, the trunnion ball valve is opened to repeatedly exhaust the air to recover the vacuum degree so as to ensure that the stored articles are stored under the required vacuum degree.
The utility model discloses can design into the storage of other shapes in order to adapt to different article with the vacuum tank to can upgrade the manometer into digital pressure table, send out the police dispatch newspaper when pressure is less than the value of setting for. These principles are the same and structural changes may constitute other embodiments of the present invention.
