Description
Technical field
The utility model relates to a kind of suction valve, particularly a kind of energy-saving frequency conversion screw machine suction valve.
Background technique
After bleeder valve on existing frequency conversion screw machine suction valve is opened; air-flow is directly released in suction valve gas-entered passageway from radial direction; cause sticking to a small amount of lubricant oil on suction valve valve plate to be blown; oil gas is reverses through air filter; make air filter just block inefficacy because of lubricant pollution in a short time, when shutdown is released, need to carry out controlled discharge valve events by solenoid valve; cost is high, and rate of fault is high.
Summary of the invention
The purpose of this utility model is to overcome above deficiency, provides a kind of rational in infrastructure, robust performance, long service life, the screw-rod air compressor gas valve that fabricating cost is low.
The purpose of this utility model is achieved through the following technical solutions: a kind of energy-saving frequency conversion screw type suction valve, comprise air inlet valve body, air inlet valve body is provided with suction port, cavity is provided with in air inlet valve body, valve plate is connected with by mandrel in cavity, low-pressure control release valve is provided with in the upper end of suction valve, mangetic core assembly is provided with in low-pressure control release valve, low-pressure control release valve is provided with bleeder valve entrance, bleeder valve exports, bleeder valve controls mouth and leakage path, bleeder valve outlet communicates with the suction port of air inlet valve body, leakage path and bleeder valve control to be provided with Sealing between mouth.
The advantage that the utility model compared with prior art has is:
Eliminate solenoid valve; the feature of pressurising after shutting down after adopting suction valve valve dexterously; controlled discharge valve events; air-flow has walked around valve plate, and lubricant oil can not be blown, when screw machine operates again; lubricant oil returns again and is reclaimed by screw machine; solve the problem that screw machine shuts down oil spout gas, greatly reduce cost, improve reliability.
accompanying drawing illustrates:
Fig. 1 is structural representation of the present utility model;
Fig. 2 is that the B of Fig. 1 is to structural representation;
Fig. 3 is that the C of Fig. 1 is to structural representation;
Number in the figure: the outlet of 1-air inlet valve body, 2-suction port, 3-cavity, 4-mandrel, 5-valve plate, 6-low-pressure control release valve, 7-bleeder valve entrance, 8-bleeder valve, 9-bleeder valve control mouth, 10-leakage path, 11-Sealing, 12-mangetic core assembly.
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 and Fig. 3 show a kind of mode of execution of a kind of energy-saving frequency conversion of the utility model screw type suction valve: comprise air inlet valve body 1, air inlet valve body 1 is provided with suction port 2, cavity 3 is provided with in air inlet valve body 1, valve plate 5 is connected with by mandrel 4 in cavity 3, low-pressure control release valve 6 is provided with in the upper end of suction valve 1, mangetic core assembly 12 is provided with in low-pressure control release valve 6, low-pressure control release valve 6 is provided with bleeder valve entrance 7, bleeder valve outlet 8, bleeder valve controls mouth 9 and leakage path 10, bleeder valve outlet 8 communicates with the suction port 2 of air inlet valve body 1, leakage path 10 and bleeder valve control to be provided with Sealing 11 between mouth 9.
The utility model eliminates solenoid valve; the feature of pressurising after shutting down after adopting suction valve valve dexterously; controlled discharge valve events; air-flow has walked around valve plate, and lubricant oil can not be blown, when screw machine operates again; lubricant oil returns again and is reclaimed by screw machine; solve the problem that screw machine shuts down oil spout gas, greatly reduce cost, improve reliability.
