Abstract
The invention provides a pressure reducing valve. Multiple pipelines used for reducing pressure can be omitted. A valve core and a valve seat of the valve are designed to be stair shape and are mutually matched to realize sealing. The pressure reducing valve provided by the invention has the advantages of simple structure and low cost, the construction cost of the pressure reducing pipelines is greatly reduced, and maintenance is convenient.
Description
Technical field
The present invention relates to the gas-liquid control field of circulation, specifically a kind of pressure loading valve.
Background technique
The pipeline decompression is a great problem in the gas-liquid circulation construction, and usual way is on the pipeline of gas-liquid circulation, a plurality of turnings to be set, and is used for progressively releasing the pressure; The turning that is used to reduce pressure more for a long time; Not only great in constructing amount, and in case when breaking down, maintenance is difficulty comparatively also.
Summary of the invention
For addressing the above problem, the invention provides a kind of pressure loading valve, can save the many pipelines that are used to reduce pressure.
The present invention is achieved in that the spool of valve becomes stair shape with seat design, coincide each other and realizes sealing.
The invention has the beneficial effects as follows: simple in structure, cost is low, has alleviated the construction cost of gas relief line greatly, and is easy to maintenance.
Description of drawings
Be described further below in conjunction with accompanying drawing.
Fig. 1 is a structural representation of the present invention.
Among the figure 1, valve rod, 2, spool, 3, valve seat, 4, liquid entering hole, 5, liquid outlet.
Embodiment
As shown in the figure, the spool 2 and the valve seat 3 of valve are designed to stair shape, coincide each other and realize sealing.
During use, rotate valve rod 1, spool 2 separates with valve seat 3; Liquid is got in the valve by liquid entering hole 4; The gap of being made up of spool of stair shape 2 and valve seat 3 forms down the narrow wide path of, the effective flow that passes through of controlling liquid, and the pipeline that the bending in gap replacement bends plays decompression.
Claims (1)
1. a pressure loading valve is characterized in that, the spool of valve becomes stair shape with seat design, coincide each other and realizes sealing.
