This pressure gauge is particularly useful in the oil, chemical, and natural gas industries because the working environment of these industries often contains high concentrations of hydrogen sulfide gas, which has a strong corrosive effect on ordinary metal materials, and the equipment is also often subjected to vibration problems.

[0003] The existing anti-vibration and anti-sulfur pressure gauge has weak installation strength for external pipelines, and is inconvenient for workers to disassemble and maintain, which is easily corroded and damaged by sulfur-containing gases in the external environment, resulting in damage and leakage at the connection part of the pressure gauge and the pipeline, and reducing the working efficiency of the pressure gauge. UTILITY MODEL CONTENTS

[0013] A limiting assembly is arranged in the sliding groove and connected with the connecting block to limit the sliding connecting block.

[0014] An elastic assembly is arranged in the sliding groove to limit and support the limiting assembly.

[0015] As a preferred scheme of the utility model, each group of the limiting assembly comprises:

[0016] Two limiting grooves are arranged on the inner walls of the two sides of the sliding groove, and the inner surfaces of the two limiting grooves are slidably connected with the limiting blocks; and the proximal ends of the two limiting blocks are fixedly connected with the two side ends of the connecting block.

[0017] As a preferred scheme of the utility model, each group of the elastic assembly comprises:

[0018] Two springs are arranged on the inner surfaces of the two limiting grooves, and the outer surfaces of the two springs are fixedly connected with the one side end of the two supporting plates; and the one side end of the two limiting blocks is fixedly connected with the supporting plate.

[0023] Compared with the prior art, the utility model has the advantages of:

[0024] 1. In this design, the length is extended by the elastic force of two springs. Under the action of force, two limiting blocks slide inside the two limiting grooves respectively. At the same time, the two limiting blocks are fixed to both ends of the connecting block, which limits the sliding connecting block. According to the anti-detachment plate and the two limiting blocks, even under strong vibration, the connecting block will not accidentally come off. The two support plates slide with the two limiting blocks, which protects the two springs when the length is contracted, preventing the two springs from deforming and pushing the connecting block into the connecting groove when contracting. Then, the fixing screws are tightened to fix the connecting block and the connecting seat. This strengthens the installation strength of the shock-resistant and sulfur-resistant pressure gauge for external pipelines, facilitates disassembly and maintenance by workers, reduces the degree of corrosion damage from sulfur-containing gases in the external environment, avoids damage and leakage at the connection between the pressure gauge and the pipeline, and improves the working efficiency of the pressure gauge.

[0025] 2. In this solution, the use of a conical shell and a conical seat further improves the sealing performance and mechanical strength, while providing an additional protective layer. The conical shell is connected to the conical seat by threads, and its outer surface has anti-slip grooves, making it easy to tighten or loosen by hand. This design not only enhances safety but also simplifies on-site maintenance. Attached Figure Description
