Problems solved by technology

[0003] Due to the unstable working pressure of the refueling system, oil filling equipment often suffers from overpressure and loss of pressure in the pipeline, and water hammer caused by a sharp increase and decrease in pipeline pressure.
These phenomena are not conducive to the maintenance of filling equipment, and may easily lead to equipment failure.

Embodiment Construction

[0021] Below in conjunction with accompanying drawing, the present invention will be further described:

[0022] Such as figure 1 1. Structural composition and working principle

[0023] The pilot pressure regulating valve consists of two parts, the main valve and the pilot valve, such as figure 1 shown. It consists of main valve body, main valve core, main valve spring, main valve core damping hole, pilot valve body, pilot valve core, pilot valve spring, adjustment handle, buffer hole, pressure introduction hole and diversion hole, etc., such as figure 2 shown.

[0024] Pilot pressure regulating valve structure:

[0025] The main valve adopts a slide valve structure, mainly including the main valve body, the main valve core, the main valve spring and the damping hole of the main valve core. The cavity is connected to form a pressure self-balancing structure, so that the force of the valve core is not affected by the change of the pressure of the conveyed medium. Its cl...

Abstract

The invention claims to protect a pilot control branch pipeline flow stabilization regulation apparatus which comprises a main valve and a pilot valve. The main valve comprises a main valve body, a main valve inlet positioned in the lower part of the main valve body and a main valve element lower cavity; a main valve element is mounted inside the main valve body; the main valve element is communicated with the main valve element lower cavity by a main valve element damping hole; the main valve element is connected with a main valve element upper cavity; a main valve spring is arranged at the middle position of the main valve element upper cavity; one end of the main valve spring is fixed on the main valve element, and the other end of the main valve spring is positioned at the upper part of the main valve element upper cavity; the pilot valve comprises a pilot valve body and a regulation handle arranged in the pilot valve body; the regulation handle is provided with a pilot valve spring along the axial end; a pilot valve element is arranged in the pilot valve body; an inner cavity of the pilot valve body is communicated with the main valve element lower cavity by a buffer hole; by a piston, the pilot valve element interacts with a pressure medium at a pressure acquisition point, which is introduced by a pressure introduction hole. The apparatus balances and regulates pressure in a refueling pipeline.

Description

technical field [0001] The invention relates to a pressure pipeline device in the mechanical field, in particular to a pipeline steady flow regulating device. Background technique [0002] In the existing pipelines, the oil filling equipment needs to maintain the stability of pressure, flow and other parameters or control them within a certain range in many cases to ensure the safety and normal operation of the equipment. However, the high pressure of many equipments can easily lead to pipeline damage, thereby causing safety accidents such as pipeline rupture. In the prior art, there is no device for balancing and adjusting the pressure of the pipeline. Therefore, it is urgent to design a device that can balance and adjust the pipeline pressure. [0003] Due to the unstable working pressure of the refueling system, oil filling equipment often suffers from overpressure and loss of pressure in the pipeline, and water hammer caused by a sharp increase and decrease in pipeline ...
