Problems solved by technology

The existing plunger-type regulating angle valve can meet the use requirements of most occasions, but in the process of disengaging the valve core from the valve seat, the opening of the valve port changes greatly, and the flow rate increases suddenly, which is easy to cause pressure fluctuations, which is not conducive to plunger-type valves. pressure relief valve work

Embodiment 1

[0023] Such as Figure 1~4 As shown, the present invention is a baffle-type depressurization device, comprising a pipeline 1 and five pieces of one-sided channel baffles 2 and one piece of double-sided channel baffles 3 arranged on the inner wall of the pipeline 1; One edge of sheet 2 fits and connects with the inner wall of the pipeline 1, and a gap is formed between the other edge and the inner wall of the pipeline 1; the double-sided channel stopper 3 has two edges adapted to the inner wall of the pipeline 1 and connected, the remaining two sections of edges form a gap with the inner wall of the pipeline 1, and the fluid flows through the gap; the gap between two adjacent one-sided channel baffles 2 and the inner wall of the pipeline 1 forms a dislocation distribution, and the two sides The channel blocking piece 3 is arranged at the outlet of the pipeline 1 . A hollow tube 4 is arranged between two adjacent said baffles.

Embodiment 2

[0028] Such as Figure 5-6 As shown, the present invention is a baffle-type depressurization device, comprising a pipe 1 and a baffle 5 provided with an axial through hole on the inner wall of the pipe 1, and the section of the axial through hole is surrounded by arcs and chords. In this way, the outer circle of the baffle 5 with the axial through hole is adapted to the inner wall of the pipeline 1, and the fluid flows through the axial through hole; two adjacent baffles with the axial through hole The axial through holes of 5 form a dislocation distribution in the pipeline 1; a sleeve 6 whose outer circle is adapted to the inner wall of the pipeline 1 is arranged between two adjacent baffles 5 with axial through holes . Put the baffle 5 and sleeve 6 with the axial through hole into the heated pipeline 1 after cooling, and after returning to room temperature, the pipeline 1 and the baffle 5 with the axial through hole, the pipeline 1 and the The casing 6 is tightly connected...

Abstract

The invention discloses a baffle-type decompression device, which comprises a pipeline and a baffle arranged on the inner wall of the pipeline; at least one edge of the baffle is adapted to and connected with the inner wall of the pipeline, and other Part and the inner wall of the pipe form a gap for fluid to pass through. The baffle-type decompression device has the characteristics of simple structure, convenient use, and can meet different pressure-reducing requirements by adjusting the size of the gap between the baffle and the pipe, the number of baffles and the distance between the baffles.

Description

technical field [0001] The invention relates to the technical field of pressure reducing devices for fluids, in particular to a baffle type pressure reducing device. Background technique [0002] Plunger pressure-reducing devices are widely used in oil, natural gas, water treatment and other fluid transportation fields. Existing plunger-type pressure-reducing devices for fluid pressure reduction have complex structures, including valve stems, plunger valve cores, valve covers, and valve bodies. , by controlling the plunger spool to move up and down to control the opening of the valve port, the flow adjustment of the valve is realized. The existing plunger-type regulating angle valve can meet the use requirements of most occasions, but in the process of disengaging the valve core from the valve seat, the opening of the valve port changes greatly, and the flow rate increases suddenly, which is easy to cause pressure fluctuations, which is not conducive to plunger-type valves. ...
