Description
Technical field
The utility model relates to reciprocal compressor technical field of pressure detection, especially a kind of novel exhaust control valve unit that can detect cylinder pressure.
Background technique
Reciprocal compressor is a kind of common equipment being widely used in petrochemical industry.According to statistics, the fault of existing reciprocal compressor more than 60% is directly or indirectly relevant to outlet valve, therefore the fault diagnosis for outlet valve has particularly important meaning for the maintenance of reciprocal compressor and maintenance, to go forward side by side row relax statistics if the change of the cylinder pressure of reciprocal compressor to be carried out real-time monitoring, reliable foundation can be provided to the safe operation of reciprocal compressor and in good time maintenance.
Because existing most of reciprocal compressor does not arrange pressure preformed hole, therefore for the solution that the problems referred to above are existing be generally need on the casing wall of cylinder body direct perforate detect, but this mode of execution has high technological requirement to form of construction work on the one hand, on the other hand because needs destroy original housing structure, therefore in the process implemented, both likely scrapped whole cylinder body unless you give your whole attention to it, there is higher risk.
Model utility content
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of novel exhaust control valve unit that can detect cylinder pressure that a kind of rational in infrastructure, technique is simple, risk is less, with low cost.
The utility model is achieved through the following technical solutions:
A kind of novel exhaust control valve unit that can detect cylinder pressure, comprise valve body, air valve bolt is coated with in this valve body, it is characterized in that: described air valve bolt inner edge is axially throughly shaped with pressure-taking hole along it, both sides inside and outside the cylinder body that these pressure-taking hole two ends are communicated with reciprocal compressor respectively, the end that described pressure-taking hole is positioned at outside reciprocating compressor cylinder body is communicated with the side end being provided with pressure part, and the end side of this pressure part is communicated with the input end being provided with a pressure transducer.
And the input end of described pressure transducer is provided with hand valve with being communicated with between pressure part, and the end outer rim that this hand valve contacts with pressure part is set with seal arrangement, the fixing device for installing mutually with reciprocating compressor cylinder body is installed outside described seal arrangement.
And, described seal arrangement comprises the upper Sealing and lower seal that mutually can lock installation, described lower seal is sleeved on the end of pressure part, hand valve outer rim above this lower seal is set with described upper Sealing, the inner edge of described lower seal is shaped with groove, is closely equipped with packing inside this groove with in the gap of the formation of pressure part outer rim.
And described fixing device comprises a flange, make a mounting hole inside this flange, described mounting hole is closely sleeved on the outer rim of described lower seal.
And, the output terminal connection data processing terminal of described pressure transducer.
Advantage of the present utility model and good effect are:
In the utility model, the pressure-taking hole that the air valve bolt installed in valve body is made coordinates pressure part and pressure transducer, pressure in reciprocating compressor cylinder body in use can be carried out real-time collection to detect, and analyzed by the data processing terminal that pressure transducer output terminal connects, thus ensure safe operation and the maintenance in good time of reciprocal compressor; The upper Sealing that described seal arrangement comprises, lower seal and packing can the ends of effective sealing pressure part, and the Leakage Gas avoiding outlet valve to discharge or the gas of outside enter pressure part, thus ensure the accuracy of image data; The fixing device of installing outside described seal arrangement is convenient to the installation of outlet valve, and due to reciprocal compressor, that vibrations occur in running is comparatively large, therefore adopts the mode of flange to install its mounting type more simple and comparatively stablize difficult drop-off after installation.
