The utility model discloses with have rational in infrastructurely, the performance is firm, can control the pressure of breathing in, guarantees that compressor -running is smooth and easy, the advantage of shutting down the phenomenon can not appear transshipping.
Description
Technical field
The utility model relates to a kind of suction valve, particularly a kind of suction valve for coal bed gas compressor.
Background technique
At present for coal bed gas compressor in running; because the pressure of inspiration(Pi) of its suction valve is unstable; sometimes be negative pressure; sometimes be malleation; when malleation exceedes certain value, overload of compressor will be caused, and the pressure of inspiration(Pi) of coal bed gas compressor can not get controlling; so compressor often there will be the phenomenon of the overload shutdown because pressure of inspiration(Pi) is too high, thus affect carrying out smoothly of production.
Summary of the invention
The purpose of this utility model is to overcome above deficiency, and provide a kind of rational in infrastructure, robust performance, controls pressure of inspiration(Pi), ensures that compressor operating is smoothly for the suction valve of coal bed gas compressor.
The purpose of this utility model is achieved through the following technical solutions: a kind of suction valve for coal bed gas compressor, comprise suction valve valve body, described suction valve valve body is provided with intakeport and relief opening, valve plate is provided with in described intakeport, described suction valve valve body is provided with Proportional valve and pressure tap, on one end of intakeport, one end of valve rod is connected with at described suction valve valve body, the other end connecting rod of described valve rod is connected with one end of joint shaft bearing, and the other end of described joint shaft bearing is connected with Proportional valve by servo cylinder; Described servo cylinder is provided with cylinder exhaust port; Described Proportional valve is provided with exhaust port and proportional valve control access port, is provided with proportion adjustment screw in described Proportional valve upper end.
The advantage that the utility model compared with prior art has is:
Rational in infrastructure, robust performance, can control pressure of inspiration(Pi), ensures that compressor operating is smooth and easy, there will not be overload shutdown phenomenon.
accompanying drawing illustrates:
Fig. 1 is structural representation of the present utility model;
Fig. 2 is stereogram of the present utility model;
Number in the figure: 1-valve body, 2-intakeport, 3-relief opening, 4-valve plate, 5-Proportional valve, 6-pressure tap, 7-valve rod, 8-connecting rod, 9-joint shaft bearing, 10-servo cylinder, 11-cylinder exhaust port, 12-exhaust port, 13-proportional valve control access port, 14-proportion adjustment screw.
embodiment:
In order to deepen understanding of the present utility model, below in conjunction with embodiment and accompanying drawing, the utility model is described in further detail, and this embodiment, only for explaining the utility model, does not form the restriction to the utility model protection domain.
As Fig. 1-2 shows the embodiment of a kind of suction valve for coal bed gas compressor of the utility model: comprise suction valve valve body 1, described suction valve valve body 1 is provided with intakeport 2 and relief opening 3, valve plate 4 is provided with in described intakeport 2, described suction valve valve body 1 is provided with Proportional valve 5 and pressure tap 6, on one end of intakeport 2, one end of valve rod 7 is connected with at described suction valve valve body 1, the other end connecting rod 8 of described valve rod 7 is connected with one end of joint shaft bearing 9, and the other end of described joint shaft bearing 9 is connected with Proportional valve 5 by servo cylinder 10; Described servo cylinder 10 is provided with cylinder exhaust port 11; Described Proportional valve 5 is provided with exhaust port 12 and proportional valve control access port 13, is provided with proportion adjustment screw 14 in described Proportional valve 5 upper end.
When the compressor is operated, gas enters suction valve from intakeport, then enters compressor from suction valve outlet, by adjustment valve plate opening angle, can control the size of compressor air suction amount.When downstream pressure is excessive, proportional valve control access port pressure raises, and servo cylinder controls valve plate and reduces opening angle, and compressor air suction amount reduces, and downstream pressure reduces; When downstream pressure is too low, proportional valve control access port pressure reduces, and servo cylinder controls valve plate and strengthens opening angle, and compressor air suction amount increases, and downstream pressure raises.
The utility model senses the pressure of coal bed gas compressor intakeport in real time, when intakeport pressure reaches certain value, pressure measuring mechanism outputs signal in suction valve butterfly valve mechanism, control suction valve part to close, if pressure of inspiration(Pi) is also in rising, output signal strength strengthens, suction valve continues to cut out, when pressure of inspiration(Pi) no longer rises, output signal strength remains unchanged, suction valve remains on current aperture, when drop of suction pressure, output signal strength reduces, suction valve part is opened, pressure of inspiration(Pi) continues to decline, suction valve continues to open, control pressure of inspiration(Pi) with this and be no more than value range, ensure under the operating mode of pressure of inspiration(Pi) instability, compressor can not because pressure of inspiration(Pi) is too high overload shutdown.
