Description
Technical field
The utility model relates to a kind of accessory of air compressor, specifically refers to a kind of step-less adjustment suction valve.
Background technique
Air compressor is the basic product of the modernization of industry, and that often says electrically and in automation just has entirely pneumatic implication; And air compressor is just to provide source of the gas power, it is the main body in the dynamo-electric bleed air source device of nucleus equipment of pneumatic system, it is the device mechanical energy of former dynamic (normally motor) being converted to gas pressure energy, is compressed-air actuated pressure generator.The kind of air compressor is a lot, and can be divided into positive displacement compressor by working principle, speed mode compressor, the working principle of positive displacement compressor is the volume of pressurized gas, and the density of gas molecule in per unit volume is increased to improve compressed-air actuated pressure; The working principle of speed mode compressor improves the movement velocity of gas molecule, and the kinetic transformation that gas molecule is had is the pressure energy of gas, thus improves compressed-air actuated pressure.Now conventional air compressor has piston type air compressor, screw air compressor (screw air compressor is divided into again double-screw type air compressor and single screw air compressor); Centrifugal compressor and sliding-vane air compressor; Scroll type air compressor etc.
Be no matter the air compressor of what type, all need to suck air, because namely just relate to a necessary constituent elements is suction valve.The inventor of present patent application finds in actual use, there are following two deficiencys in suction valve of the prior art: 1, the control of suction valve is that mechanical type controls, in fact this control structure can not realize the control of the 0-100% of air inflow, because it just by the pressure size of establishing cushion gas end of machine, carries out loading and unloading.The valve plate that mechanical manipulator controls to open and close suction valve can not carry out the size of precise hard_drawn tuhes air inflow according to the change size of pressure, and (general air inlet adjustment is at 30%-100%, standard-sized sheet or when system pressure reaches setting value, valve plate can not Close All).So just cause at air compressor when adding unloading pressure, controller than action more frequently, can impact machine performance, and compares waste power of motor in same operating mode.2, the emptying assembly on suction valve of the prior art is independently arranged on outside valve body, not only easily occurs leak source, also create the waste of pipeline during actual use.
Model utility content
The technical problems to be solved in the utility model is, provides one to realize standard-sized sheet, the air-suction state of full cut-off, and the tolerance that can realize 0-100% regulates, and collects relieving pressure function together, simple and stable structure, the step-less adjustment suction valve of easy maintenance and installation.
For solving the problems of the technologies described above, the technological scheme that the utility model provides is: a kind of step-less adjustment suction valve, and it comprises suction port, servo driver, valve body, intake leaf and emptying assembly; Described suction port is arranged at the top of valve body, and be connected with the intake leaf of the folding controlling suction port in described suction port, described servo driver is installed on valve body, and the rotating shaft of described servo driver is connected with intake leaf; Described emptying assembly and valve body are shaped, and the bleed passage of emptying assembly directly docks with the vent in valve body.
After adopting said structure, the utility model has following beneficial effect: in the operation process of air compressor, and the suction valve of said structure can realize standard-sized sheet, the air-suction state of full cut-off, and the tolerance that also can realize 0-100% regulates.This suction valve collection is released, and servo switch is controlled in one.Structure is simple, easy maintenance and installation.Air compressor is when load or unload, and the pressure of internal system, can carry out by this suction valve the object that adjusting air inflow quantity reaches energy-conservation.The servo driver of suction valve, receives the signal of system pressure sensor, carrys out the suction valve valve plate of regulating and controlling suction port, thus the size realizing air inflow controls, and reduces acting, reach energy-conservation effect to main frame.When the fluctuation of exhaust end exhaust pressure is larger, when system pressure is lower than setting value, suction valve automatically regulates and opens.Until reach system pressure requirements.Otherwise when system pressure is higher than setting value, suction valve regulates cut out automatically.Now the emptying function of this suction valve is also with work, with the pressure balance of safeguards system.Integrated emptying assembly design, decreases the leak source of whole valve in addition, also saves pipeline and connects.
In sum, the utility model provides one can realize standard-sized sheet, the air-suction state of full cut-off, and the tolerance that can realize 0-100% regulates, and collects relieving pressure function together, simple and stable structure, the step-less adjustment suction valve of easy maintenance and installation.
Accompanying drawing explanation

Fig. 2 is the sectional view of the utility model step-less adjustment suction valve.
As shown in the figure: 1, suction port, 2, servo driver, 3, valve body, 4, intake leaf, 5, emptying assembly.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
By reference to the accompanying drawings 1 and accompanying drawing 2, a kind of step-less adjustment suction valve, it comprises suction port 1, servo driver 2, valve body 3, intake leaf 4 and emptying assembly 5; Described suction port 1 is arranged at the top of valve body 3, and be connected with the intake leaf 4 of the folding controlling suction port in described suction port 1, described servo driver 2 is installed on valve body 3, and the rotating shaft of described servo driver 2 is connected with intake leaf 4; Described emptying assembly 5 is integrally formed with valve body 3, and the bleed passage of emptying assembly 5 directly docks with the vent in valve body 3.
After adopting said structure, the utility model has following beneficial effect: in the operation process of air compressor, and the suction valve of said structure can realize standard-sized sheet, the air-suction state of full cut-off, and the tolerance that also can realize 0-100% regulates.This suction valve collection is released, and servo switch is controlled in one.Structure is simple, easy maintenance and installation.Air compressor is when load or unload, and the pressure of internal system, can carry out by this suction valve the object that adjusting air inflow quantity reaches energy-conservation.The servo driver of suction valve, receives the signal of system pressure sensor, carrys out the suction valve valve plate of regulating and controlling suction port, thus the size realizing air inflow controls, and reduces acting, reach energy-conservation effect to main frame.When the fluctuation of exhaust end exhaust pressure is larger, when system pressure is lower than setting value, suction valve automatically regulates and opens.Until reach system pressure requirements.Otherwise when system pressure is higher than setting value, suction valve regulates cut out automatically.Now the emptying function of this suction valve is also with work, with the pressure balance of safeguards system.Integrated emptying assembly design, decreases the leak source of whole valve in addition, also saves pipeline and connects.
In sum, the utility model provides one can realize standard-sized sheet, the air-suction state of full cut-off, and the tolerance that can realize 0-100% regulates, and collects relieving pressure function together, simple and stable structure, the step-less adjustment suction valve of easy maintenance and installation.
It should be noted that suction valve is ripe parts in air compressor, it also comprises some other general structure, owing to there is no substantial annexation between the inventive point in other structure and present patent application, so be no longer described in detail in present patent application.
