technical field

The invention belongs to the technical field of fluid pipeline fittings, in particular to an energy-saving booster valve for pipelines.

Background technique

Based on the equipment and accessories transported by fluid pipelines, in some cases, it is necessary to pressurize the fluid in the pipeline. The pressure valve is connected, and the system pressure is increased to reach the pressure required by the system.

Chinese patent CN102126489B discloses an emergency booster valve, which includes a booster valve sleeve communicated with the train pipe, auxiliary air cylinder and volume chamber respectively. A booster valve rod is arranged in the booster valve sleeve. The rod is equipped with a pull rod, a pull rod sleeve and a plunger. This invention can effectively control the pressure in the volume chamber by moving the booster valve rod, pull rod and plunger in the booster valve sleeve, and then cooperating with the position setting of each sealing ring. 0 rises to 400kPa and when the pressure of the working air cylinder drops from 450kPa to 50-100kPa, it suddenly accelerates and relieves to zero. To 400kPa, the pressurization time should not be greater than 4s, and at the same time, it can also meet the two requirements that the pressure of the working air cylinder can be suddenly accelerated and relieved to zero when it drops from 450kPa to 50-100kPa.

Most of the existing energy-saving booster valves used in pipelines need to pressurize the transport medium through an external power source or air source. The pressure is used, and most of the booster valves cannot reduce the water pressure when there is no need for boosting, such as maintenance pipe sections.

Based on the above-mentioned problems, we found that the energy-saving booster valves used in pipelines in the prior art are difficult to avoid the above problems at the same time. Even if they can be solved, external energy supply or pressure relief equipment is required, resulting in increased costs and equipment Therefore, we propose an energy-saving booster valve for pipelines that can release the pressure of the medium when booster is not needed, and does not require additional energy supply.
