Problems solved by technology

[0008] A significant disadvantage of known MPVs is that they tend to have a rather high number of parts interacting with each other
This results in a considerable amount of time required to assemble such a minimum pressure valve on site, which in turn results in very high repair costs and damages associated with the compressor not running during this timeframe
[0009] Additionally, each of the components will have its own tolerances which add up and affect the overall performance of the minimum pressure valve
[0010] Furthermore, because of this large number of parts, during assembly of some of the parts (for example a spring will need to be pre-tensioned), it may be prone to damage to adjacent parts that come into contact with such a spring

Embodiment Construction

[0029] figure 1 A compressor 1 is shown comprising a compressor element 2 with a gas inlet 3 and a compressed gas outlet 4 . Typically, the compressor 1 is driven by a fixed or variable speed electric motor 5 .

[0030] In the context of the present invention, a compressor 1 is to be understood as a complete compressor device comprising the compressor element 2, all typical connecting pipes and valves, the casing of the compressor 1 and possibly the electric motor driving the compressor element 2 5.

[0031] In the context of the present invention, compressor element 2 is to be understood as a compressor element housing in which the compression process takes place by means of a rotor or by reciprocating motion.

[0032] Furthermore, said compressor element 2 may be selected from the group comprising screws, teeth, claws, scrolls, rotating blades, centrifugals, pistons and the like.

[0033] now refer to figure 1 , the compressor 1 also comprises a pressure vessel 6 having ...

Abstract

The invention relates to a minimum pressure valve comprising a housing with a valve inlet and a valve outlet connected by means of a chamber, the minimum pressure valve further comprising a valve body in said chamber movable between a closed position in which the valve inlet is closed and an open position in which the valve inlet is open, wherein the minimum pressure valve further includes A regulating unit for setting a pressure value at which the valve body moves into an open position.

Description

technical field [0001] The invention relates to a minimum pressure valve comprising a housing with a valve inlet and a valve outlet connected by means of a chamber, the minimum pressure valve also comprising a valve body , the valve body is movable in the chamber between a closed position in which the valve inlet is closed and an open position in which the valve inlet is open of. Background technique [0002] Known compressor installations generally comprise a minimum pressure valve (hereinafter abbreviated MPV), which is usually installed at the outlet of a pressure vessel which can be used to separate liquid from the compressed gas leaving the compressor element (e.g. In the case of oil-injected compressors for the purpose of oil). [0003] By injecting a liquid, such as oil, into the compressor element of the compressor during the compression of the gas, the temperature rise of the compressed gas can be kept under control. The cooling liquid is usually separated from t...
