Abstract
The utility model belongs to the technical field of air compressors, and particularly relates to an emptying valve on an air compressor. The emptying valve comprises a valve element, a valve rod and valve body. One end of the valve rod is provided with the valve element, and a spring is sleeved on a valve rod. A step through hole is axially formed in the valve body, and a valve seat and a spring seat are arranged in the valve body in sequence from top to bottom. The lower end of the spring is arranged on the spring seat, and the upper end of the spring is connected with the valve element in a contacting mode. The valve element is movably arranged on the valve seat. The emptying valve enables the air compressor to be easily started, reduces energy consumption of a motor, and starts low load of the air compressor.
Description
Technical field:
The utility model belongs to the air compressor technical field, refers in particular to the atmospheric valve on a kind of air compressor.
Background technique:
Air compressor is by motor direct driving compressor machine, bent axle is produced rotatablely move, and drivening rod makes piston produce to-and-fro motion, causes that volume of cylinder changes.When the cylinder in air compressor has pressure, exist electric motor starting power large, be difficult for to start the defective such as energy consumption of electrical machinery is large.
Summary of the invention:
The purpose of this utility model be to provide a kind ofly reduce energy consumption of electrical machinery, easily start, the atmospheric valve on the air compressor of Low loading start up.
The utility model is achieved in that
Atmospheric valve on air compressor, include spool, valve rod and valve body, an end at valve rod is provided with spool, be set with spring outside valve rod, axially be provided with step through-hole and be formed with successively valve seat and spring seat from top to bottom in valve body, the lower end of spring is arranged on spring seat, the upper end is connected with the spool contact, and spool is movably arranged on valve seat.
End near valve seat on above-mentioned valve body is provided with joint, and joint is connected on the one-level cylinder and the pipeline between secondary cylinder of air compressor.
The advantage that the utility model is given prominence to compared to existing technology is:
The utility model can make air compressor easily start, and reduces energy consumption of electrical machinery, makes the air compressor Low loading start up.
Description of drawings:
Fig. 1 is structural representation sketch of the present utility model.
Embodiment:
The below is further described the utility model with specific embodiment, referring to Fig. 1:
Atmospheric valve on air compressor, include spool 10, valve rod 20 and valve body 30, an end at valve rod 20 is provided with spool 10, be set with spring 40 outside valve rod 20, be formed with successively valve seat 60 and spring seat 70 from top to bottom at the interior step through-hole 50 that axially is provided with between two parties of valve body 30, the lower end of spring 40 is arranged on spring seat 70, the upper end is connected with spool 10 contacts, and spool 10 is movably arranged on valve seat 60.
End near valve seat 60 on above-mentioned valve body 30 is provided with joint 80, and joint 80 is connected on the one-level cylinder and the pipeline 110 between secondary cylinder of air compressor.
Working principle of the present utility model is:
Pipeline UNICOM between valve body 10 inner chambers and one-level cylinder and secondary cylinder.During lower than spring 70 rated pressure, spool 10 lifts off a seat 60 when the pressure in cylinder, and the gas in the cylinder through holes 50 in the valve body 10 automatically discharges, when the pressure in cylinder during greater than spring 70 rated pressure, and spool 10 and valve seat 60 closures.
Above-described embodiment is only one of preferred embodiment of the present utility model; be not to limit practical range of the present utility model with this; therefore: all equivalences of doing according to shape of the present utility model, structure, principle change, within all should being covered by protection domain of the present utility model.
