[0001] The invention relates to the technical field of pipeline sight glass devices, in particular to a quick-opening pipeline sight glass device with a neck. Background Art

[0002] Pipeline sight glass devices are widely used in many fields such as petroleum, chemical industry, chemical fiber, and pharmaceutical industry. They are one of the main accessories on industrial pipeline devices. Through them, the flow reaction of liquid, gas, steam and other media in the pipeline can be observed at any time, production can be monitored, and accidents in the production process can be avoided. Pipeline sight glass has the characteristics of small installation size, small driving torque, simple operation, quick installation, good flow regulation function and closing seal, etc. It can be used in chemical towers with high temperature, strong corrosion, easy poisoning, high danger, and easy crystallization to ensure its safe production. The utility model introduces a quick-opening pipeline sight glass device with a neck.

[0003] In the existing technology, due to the existence of various situations such as complex and changeable media, harsh environment, and the requirement for continuity in the production and processing process, impurities or stains left by the media often remain on the internal lenses of the pipeline sight glass. For example, there will be dust on the lenses of the flue gas pipeline, steam on the lenses of the high-temperature pipeline, and oil on the lenses of the sewage pipeline. The sight glass is often easily blocked, making it difficult for workers to observe the internal working conditions of the pipeline. In addition, because the equipment is running continuously and the standard sight glass is fixed and clamped by fasteners such as bolts, the pipeline sight glass cannot be frequently disassembled to wipe the lens, making the pipeline sight glass unable to play its due role. In response to the above situation, we have made improvements and proposed a quick-opening pipeline sight glass device with a neck. Summary of the invention

[0004] In order to solve the above problems, the present invention discloses a quick-opening pipe sight glass device with a neck, comprising a steel pipe, an end cover press seat is welded to the end side wall of the steel pipe, a lower end cover is provided at the end of the end cover press seat, an upper end cover is provided at the end of the lower end cover, and tempered glass is provided between the upper end cover and the lower end cover.

Loosen the butterfly nut to disengage the buckle groove and the matching pressing edge, and the upper end cover and the lower end cover can be removed from the end cover pressure seat, and samples can be taken out from the pipeline at this time. This method has the advantage of convenient sampling.

[0006] Preferably, the side wall of the steel pipe is fixedly connected with a movable ear seat, the side wall of the lower end cover is fixedly connected with a support ear, and the support ear and the movable ear seat are hinged. That is, the upper end cover and the lower end cover can be rotated and opened relative to the end cover pressure seat. This structure makes the device an integral whole, and prevents the upper end cover and the lower end cover from falling off when opening.

[0007] Preferably, the end portions of the end cover pressing seat and the lower end cover adjacent to each other are provided with sealing grooves, and the sealing grooves are filled with sealing rings to ensure the sealing between the end cover pressing seat and the lower end cover.

[0008] Preferably, the side wall of the lower end cover is fixedly connected with a handle, which is convenient for rotating the lower end cover to open it for sampling.

[0009] Preferably, bolts are inserted into the ends of the upper end cap, and the bolts are threadedly connected to the lower end cap, that is, in this way, the tempered glass is clamped between the upper end cap and the lower end cap, and relevant sealing treatment is provided, such as adding a sealing gasket or applying glass glue.

[0010] The beneficial effects of the present invention are as follows:

[0011] 1. Based on the design concept of the original standard pipeline sight glass, the design concept of hand holes is combined, that is, cylindrical pressure blocks, screws and other components are set, and the upper and lower end covers can be opened.
