Abstract
Description
Technical Field
[0001] This utility model relates to the field of gas pipeline pressure testing, and in particular to a safety protection valve device for gas pipeline pressure testing. Background Technology
[0002] With the continued rapid growth of natural gas consumption in my country, the safety of natural gas pipelines has become increasingly prominent, placing higher demands on the safe operation and management of natural gas systems. Among these, the gas pressure regulator, as a common and important pressure regulating facility, directly affects the stability and safety of gas supply to downstream users. Commonly known as a pressure reducing valve, the gas pressure regulator is actually a special valve. As an indispensable pressure regulating device in the gas pipeline network, it automatically changes the gas flow rate to reduce pressure and maintain downstream pressure stability.
[0003] Existing intelligent pressure regulators for gas pipelines are equipped with vent pipes. When the internal pressure is too high, the gas can be released to ensure the safety of the equipment. If the vent pipe is blocked, it will be very dangerous. Therefore, a protective net is usually installed at the end of the vent pipe.
[0004] However, the patent application with publication number CN222513946U in the prior art uses a sleeve, connecting plate, mounting block and bristles. When cleaning the protective net on the exhaust pipe, the worker can directly rotate the sleeve to drive the bristles to rotate. The rotating bristles clean the protective net. The worker does not need to carry cleaning tools at all times. Therefore, it is more convenient for the worker to clean the protective net and improves its practicality.
[0005] However, current devices use a cleaning brush to remove dust when cleaning the filter, but the dust generated by the filter accumulates inside the mounting sleeve and cannot be removed.
[0006] Therefore, it is necessary to provide a safety protection valve device for gas pipeline pressure testing to solve the above-mentioned technical problems. Utility Model Content
[0007] This utility model provides a safety protection valve device for gas pipeline pressure testing, which solves the problem that in current devices, dust generated by the filter screen is accumulated inside the mounting sleeve and cannot be removed when cleaning the filter screen using a cleaning brush.

[0011] The mounting ring is disposed on one side of the surface of the exhaust pipe;

[0015] Preferably, the connecting component includes a circular block and a plurality of connecting plates, all of which are connected to the side of the circular block.
[0016] Preferably, one end of the mounting sleeve has a plurality of mounting grooves that are adapted to the plurality of connecting plates.
[0017] Preferably, a fastener is provided between the mounting sleeve and the connecting plate.
[0018] Preferably, one end of the mounting sleeve has a fixing hole that matches the fixing member.
