Abstract
The utility model relates to a one-way anti-blockage valve which comprises a valve (90), a protecting sleeve (35) and a feeding port (57), wherein the feeding port (57) is positioned at the upper end of a main body (1), the protecting sleeve (35) wraps the outer side of the main body (1), the valve (90) is positioned at one side of the main body (1) below the feeding port (57), and a high-pressure air inlet (116) is positioned on the outer wall of the main body (1) below and at the same side of the valve (90). The one-way anti-blockage valve has better stability.
Description
Technical field
The utility model belongs to the field, particularly relates to a kind of unidirectional anti-blocking valve.
Background technique
In the PTA process units, the most important control valve of refining workshop section will belong to PCV21377, and its control performance influence is great.If this valve control is unstable, directly can have influence on the quality of PTA product, cause product defective.If consequence is serious, cause hydrogenator beds front and back pressure reduction excessive, can cause beds to subside, and then cause huge equipment loss.
Drive the back after about time how half a year at my PTA2 of company device, find that this valve is uncontrollable, on-the-spot fluctuation is very big.Behind the device parking maintenance, approximately after two months, same situation appears again.
The model utility content
Technical problem to be solved in the utility model provides a kind of unidirectional anti-blocking valve, to improve stability.
The technological scheme that its technical problem that solves the utility model adopts is: a kind of unidirectional anti-blocking valve is provided; comprise valve; protecting jacket and feeding port; described feeding port is positioned at the main body upper end; protecting jacket is coated on the main body outside; valve is positioned at main body one side of feeding port below, and the high pressure admission mouth is positioned on the main body outer wall of valve with side-lower.
Described main body lower end is the filler outlet.
Beneficial effect
The utility model stability better.
Description of drawings
Fig. 1 is the utility model structural drawing.
Embodiment
Below in conjunction with specific embodiment, further set forth the utility model.Should be understood that these embodiments only to be used to the utility model is described and be not used in the restriction scope of the present utility model.Should be understood that in addition those skilled in the art can make various changes or modifications the utility model after the content of having read the utility model instruction, these equivalent form of values fall within the application's appended claims institute restricted portion equally.
As shown in Figure 1; a kind of unidirectional anti-blocking valve; comprise valve 90; protecting jacket 35 and feeding port 57; described feeding port 57 is positioned at main body 1 upper end; protecting jacket 35 is coated on main body 1 outside, and valve 90 is positioned at main body 1 one sides of feeding port 57 belows, and high pressure admission mouth 116 is positioned on main body 1 outer wall of valve 90 with side-lower.Main body 1 lower end is filler outlet 96.
