Description

Technical Field

[0001] The utility model relates to the technical field of negative pressure monitoring devices, in particular to a negative pressure monitoring device for a vacuum tank. Background Art

[0002] During the use of the vacuum tank, it is necessary to monitor the internal pressure state of the vacuum tank in real time to prevent the internal pressure of the vacuum tank from being too high, causing problems such as explosion of the vacuum tank. In the prior art, a negative pressure vacuum gauge is arranged on the top end face of the vacuum tank, and a pressure probe arranged at the bottom end of the negative pressure vacuum gauge is in contact with the internal environment of the vacuum tank, so that the negative pressure vacuum gauge can monitor the negative pressure state inside the vacuum tank through the pressure probe.

[0003] The connection between the vacuum tank and the negative pressure vacuum gauge is prone to connection leakage, which will cause errors in the monitoring data of the negative pressure vacuum gauge and affect the safe use of the vacuum tank.

[0004] The main reason for the above problems is that the vacuum tank and the negative pressure vacuum gauge are mainly connected by fixings, such as threaded seats and threaded rings, and the vacuum tank and the negative pressure vacuum gauge are not connected in an integrated state. Therefore, under the influence of long-term pressure, a connection gap is prone to appear at the connection between the negative pressure vacuum gauge and the vacuum tank, causing part of the gas inside the vacuum tank to flow into the external environment through the connection gap. At present, there is no protective device on the outside of the connection between the negative pressure vacuum gauge and the vacuum tank, which destroys the pressure environment inside the vacuum tank, and further causes errors in the monitoring data of the negative pressure vacuum gauge, making it impossible to accurately control the pressure inside the vacuum tank in the later stage. In addition, the staff cannot directly see the gas leaked into the external environment with the naked eye, so that the leakage problem in the vacuum tank cannot be dealt with in time. To address the above problems, we propose a negative pressure monitoring device for a vacuum tank. Utility Model Content

[0005] In view of the deficiencies in the prior art, the utility model provides a negative pressure monitoring device, which solves the problem that connection leakage is prone to occur at the connection between the vacuum tank and the negative pressure vacuum gauge, resulting in errors in the monitoring data of the negative pressure vacuum gauge and affecting the safe use of the vacuum tank.

[0006] To achieve the above purpose, the utility model is implemented by the following technical scheme: a vacuum tank negative pressure monitoring device, including a negative pressure vacuum gauge arranged on the top end surface of the vacuum tank, and an anti-leakage mechanism is arranged outside the negative pressure vacuum gauge, and the anti-leakage mechanism includes:

DETAILED DESCRIPTION

[0024] In order to make the purpose, technical solution and advantages of the embodiments of the utility model clearer, the technical solution in the embodiments of the utility model is described clearly and completely. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] The embodiment of the present application provides a negative pressure monitoring device to solve the problem that leakage is prone to occur at the connection between the vacuum tank and the negative pressure vacuum gauge, which leads to errors in the monitoring data of the negative pressure vacuum gauge and affects the safe use of the vacuum tank. The device protects the connection between the vacuum tank and the negative pressure vacuum gauge and directly displays gas leakage problems at the connection.

[0026] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0027] The utility model embodiment discloses a negative pressure monitoring device for a vacuum tank.

[0028] According to the attached Figure 1-4 As shown, it includes a negative pressure vacuum gauge 1 arranged on the top end face of the vacuum tank, and a probe arranged at the bottom end of the negative pressure vacuum gauge 1 is in contact with the internal environment of the vacuum tank. The probe is not directly drawn in the accompanying drawings, so that the negative pressure vacuum gauge 1 can monitor the negative pressure state inside the vacuum tank through the probe.

[0029] The outside of the negative pressure vacuum gauge 1 is provided with an anti-leakage mechanism 2. When leakage occurs at the connection between the negative pressure vacuum gauge 1 and the vacuum tank, the anti-leakage mechanism 2 can be used to promptly warn of the leakage. The anti-leakage mechanism 2 includes a vacuum glass box 201. The vacuum glass box 201 is made of a transparent material, so that when the negative pressure vacuum gauge 1 is covered inside the vacuum glass box 201, it will not hinder the staff from directly viewing the data on the negative pressure vacuum gauge 1. The vacuum glass box 201 is covered on the outside of the negative pressure vacuum gauge 1. The bottom end face of the vacuum glass box 201 is fixedly connected to the top end face of the vacuum tank. A box cover 202 is provided on the top end face of the empty glass box 201, and a locking screw 205 for locking the box cover 202 and the vacuum glass box 201 is rotatably connected to the outer wall of the box cover 202, and a sealing plug 203 is fixedly connected to the bottom end face of the box cover 202, and the sealing plug 203 is plugged into the inside of the vacuum glass box 201. Through the combined vacuum glass box 201 and the box cover 202, the connection between the negative pressure vacuum gauge 1 and the vacuum tank is isolated from the external environment. Even if there is a leak at the connection between the negative pressure vacuum gauge 1 and the vacuum tank, the leaked gas will be confined inside the vacuum glass box 201.

[0030] The warning component 204 is arranged on the top end face of the vacuum glass box 201. The warning component 204 is used to give a warning during the use of the negative pressure vacuum gauge 1. That is, if there is a leak at the connection between the negative pressure vacuum gauge 1 and the vacuum tank, the gas at the leaking part will be limited inside the vacuum glass box 201. At this time, the gas inside the vacuum glass box 201 will prompt the warning component 204 to operate, so as to more conspicuously remind the staff that there is a gas leakage problem in the vacuum tank. The warning component 204 includes a connecting hole 2041, and the connecting hole 2041 is opened on the top end face of the box cover 202. The balloon 2042 is connected to the top end face of the box cover 202. In addition to the balloon 2042, it can also It is possible to use other devices that can receive gas and expand to different degrees when receiving different gases. The balloon 2042 is connected to the interior of the vacuum glass box 201 through the connecting hole 2041. The top end face of the box cover 202 is fixedly connected with a threaded ring seat 2043. The outer wall of the port of the balloon 2042 is fixedly connected with a threaded collar 2044. One end of the threaded collar 2044 is threadedly sleeved on the outer wall of the threaded ring seat 2043. The threaded ring seat 2043 is located directly above the connecting hole 2041. The balloon 2042 and the connecting hole 2041 can be combined by setting the threaded collar 2044 and the threaded ring seat 2043.

[0031] The vacuum tank negative pressure monitoring device is provided with an anti-leakage mechanism 2 on the outside of the vacuum tank negative pressure monitoring device, so that when leakage occurs at the connection between the negative pressure vacuum gauge 1 and the vacuum tank, the anti-leakage mechanism 2 can promptly receive the leaked gas, and through the early warning component 204 provided at the anti-leakage mechanism 2, the leakage situation can be directly and conveniently observed, thereby facilitating the staff to promptly protect the safety of the vacuum tank and the negative pressure monitoring device at the vacuum tank.
