Description
Technical Field
The utility model relates to an automatic vapor pressure tester, especially an automatic vapor pressure tester of airtight vacuum test chamber is opened in automation that can reduce the cost of labor, improve efficiency of software testing and reliability.
Background
Vapor pressure is an important physical indicator of volatile liquids. The national petrochemical industry standard SH/T0794-2007 micro-method for measuring the vapor pressure of petroleum products specifies a method for measuring the vapor pressure of petroleum products, and specifically, an air saturated sample with a known volume is cooled and added into a constant-temperature vacuum test chamber, the pressure of the test chamber is measured after the heat balance is achieved at 37.8 ℃, and the total vapor of the measured sample is converted into an equivalent value of dry vapor pressure. The existing automatic vapor pressure measuring device (micro method) is provided with a vacuum test chamber, a control module (a single chip microcomputer, a PLC and the like), a pressure sensor, a temperature controller, a heating element, a display screen and the like which are connected with the control module, wherein the top end of the vacuum test chamber is provided with an upper port, a pressing block is in threaded connection with the upper port, and the pressing block is provided with an injection hole coaxial with the upper port and a sealing gasket positioned below the injection hole. Before sample introduction, the pressing block is manually screwed to realize sealing, and the syringe needle penetrates through the sealing pad to introduce a sample from the upper port; after the test, the pressure relief is realized by manually loosening the pressing block. There are the following problems:
1. the rotary spiral pressing block is easy to generate abrasive dust to fall into a test chamber, so that the sample is polluted, and the faults of devices such as an electromagnetic valve and the like are caused;
2. the test failure caused by the damage or the untight sealing of the equipment can be caused by improper force of the tester;
3. manual operation wastes time and energy, improves the experiment cost and reduces the experiment efficiency.
Disclosure of Invention
The utility model relates to a solve the above-mentioned technical problem that prior art exists, provide an automatic vapor pressure tester of airtight vacuum test chamber is opened in automation that can reduce the cost of labor, improve efficiency of software testing and reliability.
The technical solution of the utility model is that: the utility model provides an automatic open automatic vapor pressure tester of airtight vacuum test chamber, has control module, vacuum test chamber and is located the last mouthful of vacuum test chamber top, be fixed with the link above the vacuum test chamber top, be fixed with the power device who meets with control module on the link, power device meets with vertical actuating lever, is connected with the briquetting arm with vertical actuating lever, briquetting arm one side meets with the briquetting, the opposite side meets with the slider, be equipped with the injection hole coaxial with last mouthful on the briquetting, be fixed with the sealed pad that is located below the injection hole on the briquetting, the slider slides with the slide rail of fixing on the link and meets.
The utility model discloses can be by the power device of control module control, through vertical actuating lever, briquetting arm etc. and then drive the briquetting be connected with it, realize automatically and compress tightly sealedly and not hard up opening with the vacuum test room suitable for reading, avoid the manual problem that exists of opening sealed vacuum test room, can reduce the cost of labor and improve efficiency of software testing and reliability.

Fig. 2 is a side sectional view of embodiment 1 of the present invention.
Detailed Description
Example 1:
the automatic vapor pressure tester for automatically opening the sealed vacuum test chamber of the utility model is shown in figure 1 and figure 2, the device is the same as the prior art, comprises a control module, a vacuum test chamber 1 and an upper port 2 positioned at the top end of the vacuum test chamber 1, different from the prior art, a connecting frame 3 is fixed on the top end of a vacuum testing chamber 1, a power device (motor) 4 connected with a control module is fixed on the connecting frame 3, an output shaft of the power device 4 is connected with a vertical driving rod (screw) 5, a pressing block arm 6 is connected with the vertical driving rod (screw) 5 through a nut thread, one side (left side) of the pressing block arm 6 is connected with a pressing block 7, the other side (right side) of the pressing block arm 6 is connected with a sliding block 8, an injection hole 9 which is coaxial with the upper opening 2 is arranged on the pressing block 7, a sealing gasket 10 which is positioned below the injection hole 9 is fixed on the pressing block 7, and the sliding block 8 is connected with a sliding rail 11 which is fixed on the connecting frame 3 in a sliding mode.
The operation process is as follows:
before sample introduction, a control module outputs a signal to start a motor 4, an output shaft of the motor 4 drives a vertical screw 5 to rotate, and a pressing block arm 6 moves downwards along a sliding rail 11 and drives a pressing block 7 and a sealing gasket 10 to be arranged on an upper port 2 and tightly pressed under the limiting of a sliding block 8, so that the vacuum test chamber 1 is sealed;
after the test, control module output signal control motor 4 reverses, and the output shaft of motor 4 drives vertical screw 5 and rotates, and under the spacing of slider 8, briquetting arm 6 moves up along slide rail 11 and drives briquetting 7, sealed pad 10 and keep away from last mouthful 2, realizes that vacuum test chamber 1 opens the pressure release.
Example 2:
the basic structure is the same as that of embodiment 1, and the difference from embodiment 1 is that the power device 4 is a cylinder connected with a control module, and a vertical driving rod 5 is fixedly connected with a briquetting arm 6.
