Technical Field

[0001] The utility model relates to the technical field of liquid level transmitters, in particular to a window installation structure of a liquid level transmitter. Background Art

[0002] Liquid level transmitter is a device widely used in industrial automation to measure and monitor liquid height. Traditional liquid level transmitters usually use bolts to install the window to ensure the stability and sealing of the window. However, this installation method has some limitations and problems:

[0003] 1. Installation complexity: Bolt-tightening installation requires multiple steps and tools, which increases the complexity and time cost of installation.

[0004] 2. Sealing problem: Tightening of bolts may lead to poor sealing, especially in an environment with vibration or temperature changes, the bolts may loosen, thus affecting the sealing performance of the equipment.

[0005] 3. Maintenance cost: The bolt-fastened windows need to be retightened during maintenance, which increases the difficulty and cost of maintenance.

[0006] 4. Safety issues: In some special environments, such as flammable and explosive occasions, bolt tightening may pose a safety hazard, because loosening of the bolts may cause the window to fall off or the seal to fail.

[0007] In order to solve the above problems, the present application provides a liquid level transmitter that does not require bolts for installation and fixation. Utility Model Content

[0008] In view of the deficiencies in the background technology, the utility model provides a window installation structure for a liquid level transmitter.

[0014] The beneficial effects of the utility model are:

[0015] 1. Simplify the installation process: By adopting a clamping mechanism instead of the traditional bolt fastening method, this application greatly simplifies the installation process of the liquid level transmitter window. The installer does not need to use multiple tools for cumbersome bolt installation, thereby reducing installation time and labor intensity.

[0016] 2. Improve sealing reliability: This application ensures the sealing between the window and the transmitter housing through the design of the sealing gasket and the pressure ring. This sealing method has significant advantages in preventing liquid or gas leakage, especially in industrial environments with harsh pressure or chemical properties.

[0017] 3. Enhanced equipment safety: Since this application does not require bolt tightening, it eliminates the potential safety hazards caused by loose or corroded bolts. In addition, the design of the clamping mechanism also makes the window more stable and not easy to fall off when subjected to external impact.

[0018] 4. Strong adaptability: The structural design of this application enables the liquid level transmitter to adapt to various industrial environments, including high temperature, high pressure, chemically corrosive environments, etc., enhancing the scope of application of the equipment.

[0019] In addition to the objects, features and advantages described above, the present invention has other objects, features and advantages.

DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only 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.

[0026] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back...), the directional indications are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0027] The utility model provides a window installation structure for a liquid level transmitter.

[0028] In this embodiment, refer to Figure 1-3 The window installation structure of the liquid level transmitter includes a transmitter housing 1 and an explosion-proof glass 2. One end of the transmitter housing is covered with a rear cover 3, and the other end is covered with a front cover 4. The front cover is provided with a viewing window 5. The viewing window is provided with a supporting step 6 for the explosion-proof glass to abut against. It also includes a sealing gasket 7 and a pressure ring 8. The transmitter housing is provided with a pressing mechanism for pressing on the pressure ring. The sealing gasket is arranged between the pressure ring and the explosion-proof glass.

[0029] The sealing gasket comprises a pressed ring 9 located between the explosion-proof glass and the pressing ring, an extension ring 11 extending into an explosion-proof gap 10 between the explosion-proof glass and the back cover, and a rear side pressing ring 12 extending between the pressing ring and the back cover.

[0030] In the above technical solution, the explosion-proof glass is directly pressed against the step by a pressing mechanism, without the need for bolts to fasten, making the window installation of the level transmitter faster and easier, reducing the installation time. In addition, the multi-layer structure design of the sealing gasket, including the pressed ring, the extension ring and the rear side pressing ring, provides a more comprehensive sealing effect, effectively preventing the leakage of liquid or gas.

[0031] Specifically, the two side surfaces of the pressed ring are provided with a plurality of convex teeth 13, and the explosion-proof glass and the pressing ring are provided with concave teeth 14 corresponding to the convex teeth.

[0032] The convex teeth on both sides of the pressed ring cooperate with the concave teeth on the explosion-proof glass and the pressing ring, providing a more secure mechanical interlock, increasing the sealing area, and enhancing the fixing effect of the explosion-proof glass. At the same time, the cooperation between the convex teeth and the concave teeth further ensures the close contact between the sealing gasket, the explosion-proof glass and the pressing ring, and improves the reliability of the seal.

[0033] Specifically, the pressing mechanism is a pressing rod 15 arranged on the transmitter housing, and a pressing block 16 pressed on a pressing ring is provided on the top of the pressing rod.

[0034] The clamping mechanism adopts the design of pressure rod and pressure block. After the front cover is closed, the pressure rod and pressure block are used to directly clamp the pressure ring, making the installation and maintenance process more convenient. The pressure block on the top of the pressure rod can directly act on the pressure ring, providing a more direct and effective clamping force to ensure the sealing and fixation of the window.

[0035] Specifically, an explosion-proof joint surface 17 is provided in the explosion-proof gap between the explosion-proof glass and the back cover.

[0036] The design of the explosion-proof joint surface provides an additional safety barrier between the explosion-proof glass and the back cover, improving the overall explosion-proof performance.

[0037] Technical personnel should note: Although the utility model has been described according to the above specific implementation methods, the concept of the utility model is not limited to this utility model. Any modification using the concept of the utility model will be included in the scope of protection of this patent right.
