Abstract
The utility model discloses an air inlet valve of a screw air compressor, which comprises a valve body, wherein an air inlet and an air outlet are arranged on the valve body, a butterfly valve is arranged at the upper part of the air inlet and connected with a cylinder, and a heavy hammer type check valve is arranged at the lower part of the air inlet in the valve body; and the air inlet valve of the screw air compressor further comprises an emptying valve connected with the cylinder, one end of the emptying valve is connected with the valve body and communicated with an inner cavity of the valve body, and the other end of the emptying valve is communicated with an electromagnetic valve. The air inlet valve of the screw air compressor can effectively prevent the faults of shutdown oil discharge; furthermore, the performances are stable, and the service life is long.
Description
Technical field
The utility model relates to a kind of screw-rod air compressor gas valve.
Background technique
The piston intake valve of screw-rod air compressor commonly used causes inrush current big easily; Can cause piston and piston seat decentraction behind the long-play, fragile Sealing, thus produce the fault of oil spout, influenced the functional reliability of whole valve.
Summary of the invention
Because the problems referred to above that prior art exists, the purpose of this utility model are to propose a kind of screw-rod air compressor gas valve,
To achieve these goals, a kind of screw-rod air compressor gas valve of the present utility model comprises that valve body, this valve body are provided with suction port and air outlet, and top, described suction port place is provided with butterfly valve, it links to each other with cylinder, and described suction port bottom is provided with the heavy hammer type safety check in the valve body; Also comprise an adjustable atmospheric valve that is connected with described cylinder, the one end is connected with valve body and is communicated with body cavity, and the other end is communicated with a solenoid valve.
As preferred embodiment of the present utility model, suction port described in the utility model and air outlet coaxial design.
As preferred embodiment of the present utility model, be provided with adjustable aperture in the atmospheric valve described in the utility model.
Owing to adopt above technological scheme; screw-rod air compressor gas valve of the present utility model can effectively prevent to shut down and tell oily fault, and antiaircraft amount can be adjusted; satisfy the requirement of different clients to pressing in the system, and characteristics such as simple in structure, easy for installation, stable performance, long service life.

Fig. 2 is the plan view of the utility model screw-rod air compressor gas valve
Fig. 3 is the worm's eye view of the utility model screw-rod air compressor gas valve
Embodiment
The utility model is described in further detail with specific embodiment with reference to the accompanying drawings below:
Shown in Fig. 1,2 and 3, a kind of screw-rod air compressor gas valve of the present utility model, comprise that valve body 5, this valve body 5 are provided with suction port 1 and air outlet 2, top, suction port 1 place is provided with butterfly valve, it links to each other with cylinder 6, air inflow is regulated in control by cylinder 6, and suction port 1 bottom is provided with the heavy hammer type safety check in the valve body 5, and it can effectively prevent to shut down tells oily fault; Also comprise an atmospheric valve 4 that is connected with cylinder 6, the one end is connected with valve body 5 and is communicated with valve body 5 inner chambers, and the other end is communicated with a solenoid valve 3.
In the present embodiment, suction port 1 and air outlet 2 coaxial design, thus can simplify the structure of this suction valve; And be provided with adjustable aperture in the atmospheric valve 4, can adjust antiaircraft valve amount according to customer requirements like this.
Working principle of the present utility model is as follows:
During with compressor start that this suction valve links to each other,, reduce and start load, press in system sets up by the little gas inlet hole of the air inlet of butterfly valve;
During compressor loads, solenoid valve gets electric, the cylinder action, and butterfly valve is all opened, the compressor build-up pressure;
During compressor unloading, the solenoid valve dead electricity, cylinder is closed, and butterfly valve cuts out, presses in keeping by the aperture air inlet, the atmospheric valve air defense, the emptying amount is adjustable, satisfies system requirements.
During the compressor shutdown, the solenoid valve dead electricity, cylinder is closed, and butterfly valve cuts out, and the heavy hammer type safety check cuts out rapidly, tells oil thereby avoid shutting down, and atmospheric valve is air defense rapidly.
But above-mentioned embodiment is exemplary, is to be the restriction that this patent is comprised scope in order better to make those skilled in the art can understand this patent, can not to be interpreted as; So long as according to spirit that this patent discloses done anyly be equal to change or modify, all fall into the scope that this patent comprises.
