Description

Technical Field

[0001] The utility model relates to the technical field of chemical instruments, and more specifically, to a chemical instrument capable of automatically releasing pressure. Background Art

[0002] Chemical instrumentation is used for chemical process control. It is an automated technical tool for detecting and controlling the process parameters of chemical processes. It can accurately and timely detect changes in various process parameters and control the main parameters to maintain them at given values ​​or rules, thereby effectively carrying out production operations and realizing production process automation.

[0003] However, the current chemical instruments have a single function and only have a detection effect. They are unable to perform automatic pressure relief work. Workers are required to monitor the equipment at all times and manually relieve pressure when the pressure is high, which makes the workers' workload heavy and easily causes safety hazards if observation is not timely.

[0008] When a chemical instrument capable of automatic pressure relief according to the technical solution is used, the cap can be automatically deployed when the pressure is high to perform pressure relief work through the joint action of the pressure relief pipe, the cap, the fixing plate and the spring. After the pressure relief is completed, the pressure relief pipe is automatically closed under the action of the rebound force of the spring. The sealing effect of the cap on the pressure relief pipe is improved by setting a rubber gasket.

[0009] Furthermore, a rubber pad is fixedly connected to the bottom of the cap, and one end of the rubber pad is inserted into the pressure relief pipe.

[0010] Furthermore, a through hole is formed on the fixing plate, a fixing rod is movably inserted into the through hole, and one end of the fixing rod is fixedly connected to the bottom of the cap.

[0011] Furthermore, the fixing plate is of hollow design.

[0012] Furthermore, one end of the spring is fixedly connected to the bottom of the rubber pad, and the other end of the spring is fixedly connected to the top of the fixing plate.

[0013] (3) Beneficial effects

[0014] In summary, the utility model has the following beneficial effects:

[0015] 1. Through the joint action of the pressure relief pipe, the cap, the fixing plate and the spring, the cap can be automatically unfolded when the pressure is high to relieve the pressure. After the pressure relief is completed, the pressure relief pipe is automatically closed under the action of the spring's rebound force. The rubber pad is provided to improve the sealing effect of the cap on the pressure relief pipe.

[0016] 2. The setting of the through hole and the fixing rod can limit the movement of the cap, and the hollow fixing plate can avoid affecting the pressure relief work. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] In order to make the technical means, creative features, objectives and effects achieved by the utility model easy to understand, the technical scheme in the specific implementation mode of the utility model is clearly and completely described below to further illustrate the utility model. Obviously, the specific implementation mode described is only a part of the implementation mode of the utility model, rather than all styles.

[0023] Example:

[0024] The following is combined with Figure 1-2 The utility model is described in further detail.

[0025] See also Figure 1-2 The utility model provides a technical solution: a chemical instrument capable of automatically relieving pressure, comprising an instrument body 1, a measuring end tube 2 is arranged at the bottom of the instrument body 1, a pressure relief tube 3 is connected to one side of the measuring end tube 2, a cap 4 is buckled at one end of the pressure relief tube 3, four fixing strips 5 are fixedly connected to the inner wall of the pressure relief tube 3, the opposite ends of the four fixing strips 5 are fixedly connected to the same fixing plate 6, a spring 7 is arranged between the top of the fixing plate 6 and the bottom of the cap 4, through the joint action of the pressure relief tube 3, the cap 4, the fixing plate 6 and the spring 7, the cap 4 can be automatically unfolded when the pressure is relatively high to perform pressure relief work, and after the pressure relief is completed, the pressure relief tube 3 is automatically closed under the action of the rebound force of the spring 7.

[0026] Specifically, a rubber pad 8 is fixedly connected to the bottom of the cap 4, one end of the rubber pad 8 is inserted into the pressure relief pipe 3, a through hole 9 is opened on the fixing plate 6, a fixing rod 10 is movably passed through the through hole 9, and one end of the fixing rod 10 is fixedly connected to the bottom of the cap 4.

[0027] By adopting the above technical solution and arranging the rubber pad 8, the sealing effect of the cover cap 4 on the pressure relief pipe 3 is improved, and the arrangement of the through hole 9 and the fixing rod 10 can limit the movement of the cover cap 4.

[0028] Specifically, the fixing plate 6 is of hollow design, one end of the spring 7 is fixedly connected to the bottom of the rubber pad 8 , and the other end of the spring 7 is fixedly connected to the top of the fixing plate 6 .

[0029] By adopting the above technical solution, the hollowing out of the fixing plate 6 can avoid affecting the pressure relief work.

[0030] The working principle of the utility model is as follows: when in use, it is installed at a suitable position on the device, and the instrument body 1 can detect the pressure inside it. When the internal pressure of the device is relatively high, the cap 4 is squeezed to move, and the cap 4 drives the spring 7 to extend, and the fixing rod 10 slides along the through hole 9, and the rubber pad 8 is separated from one end of the pressure relief pipe 3, thereby unfolding the pressure relief pipe 3 to perform pressure relief work. As the internal pressure of the device decreases, the rebound force of the spring 7 drives the cap 4 to buckle back on the pressure relief pipe 3, and the rubber pad 8 presses against the port of the pressure relief pipe 3 to seal.

[0031] This specific embodiment is merely an explanation of the present invention and is not a limitation of the present invention. After reading this specification, those skilled in the art may make non-creative modifications to the present embodiment as needed, but such modifications are protected by patent law as long as they are within the scope of the claims of the present invention.
