Technical field
The utility model relates to a kind of safety valve, relates in particular to a kind of Direct spring loaded safety valve.
Background technique
Compressor is the main body in the compressed air source unit, and it is the device that the mechanical energy of prime mover (normally motor) is converted to the gas pressure energy, is compressed-air actuated pressure generator.Safety valve is after setting; can automatically open closure according to the working pressure of setting; generally be installed on protective system safety on the equipment of locking system or the pipeline; when equipment or pipeline inner pressure surpass setting value; namely automatically open pressure release; guarantee that pressure medium remains in the specified value in the e-quipment and pipe, try to avert accidents.
Existing automobile air conditioner compressor is environmentally friendly machine R134a with refrigerant, and this product has a characteristic, and meeting when high temperature pressure is easy to cause making compressor forfeiture operational function so that the compressor internal pressure becomes rapidly large, reduction of service life, reduces reliability.
The model utility content
The technical problems to be solved in the utility model is: in order to improve the reliability of compressor, increase the service life, the utility model provides a kind of Direct spring loaded safety valve.
The technological scheme that its technical problem that solves the utility model adopts is: a kind of Direct spring loaded safety valve, the spring cup and the Sealing that comprise valve body, the spool of interior sky, the spring that is in impaction state, ring-type, described valve body bottom offers suction port, the top offers the air outlet, described spool is arranged on the bottom in the valve body, the upper end of described spool is connected with an end of spring, the other end of described spring is connected with the spring cup that is connected to suction port, and the pressure that the bottom of described spool produces by spring and Sealing and suction port are tightly connected.
In order to strengthen the sealing of suction port, the outer ring of described suction port is equipped with to the bulge loop of valve inner projection, and the bottom of described spool offers the groove of placing Sealing.
Further, particularly, the degree of depth of described groove is greater than the height of bulge loop, and the width of described groove is greater than the external diameter of bulge loop.
For the ease of spring fitting, the center of described spool upper end has columned boss, and an end of described spring is socketed on the boss.
For the ease of spring fitting, the inner ring of the spring cup of described ring-type has the rib to downward-extension, and the other end of described spring is socketed in rib.
For the ease of installation, laborsaving, the outer ring on described valve body top offers square groove.
The beneficial effects of the utility model are, Direct spring loaded safety valve of the present utility model is safe and reliable, and the pressure release flow is large, when guaranteeing the compressor normal operation, have prolonged the working life of compressor.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the optimum embodiment's of the utility model Direct spring loaded safety valve structural representation.
Fig. 2 is the utility model Direct spring loaded safety valve working state figure.
Among the figure: 1, valve body, 1-1, suction port, 1-2, air outlet, 1-3, bulge loop, 1-4, square groove, 2, spool, 2-1, boss, 3, spring, 4, spring cup, 4-1, rib, 5, Sealing.
Embodiment
By reference to the accompanying drawings the utility model is described in further detail now.These accompanying drawings are the schematic diagram of simplification, basic structure of the present utility model only is described in a schematic way, so it only show the formation relevant with the utility model.
Such as Fig. 1, shown in 2, the optimum embodiment of the utility model Direct spring loaded safety valve, the valve body 1 that comprises interior sky, spool 2, be in the spring 3 of impaction state, the spring cup 4 of ring-type and Sealing 5, valve body 1 bottom offers suction port 1-1, the top offers air outlet 1-2, spool 2 is arranged on the bottom in the valve body 1, the upper end of spool 2 is connected with an end of spring 3, the other end of spring 3 is connected with the spring cup 4 that is connected to suction port 1-1, the bottom of spool 2 is tightly connected with suction port 1-1 by pressure and the Sealing 5 that spring 3 produces, and the outer ring of valve body 1 bottom is provided with the outside thread with compressor mounting hole screw-internal thread fit.The outer ring of suction port 1-1 is equipped with to the bulge loop 1-3 of valve body 1 internal protrusion, and the bottom of spool 2 offers the groove of placing Sealing 5.The degree of depth of groove is greater than the height of bulge loop 1-3, and the width of groove is greater than the external diameter of bulge loop 1-3.The center of spool 2 upper ends has columned boss 2-1, and an end of spring 3 is socketed on the boss 2-1.The inner ring of the spring cup 4 of ring-type has the rib 4-1 to downward-extension, and the other end of spring 3 is socketed on the rib 4-1, and the outer ring on valve body 1 top also offers a circle square groove 1-4, is convenient to installation personnel and holds laborsaving.
Working principle: Direct spring loaded safety valve is to rely on the strength of spring 3 that spool 2 is pressed on the valve body, makes arranged at safety valve in closed condition, and the air-conditioning air pressure inside enters in the valve body 1 from suction port 1-1 during working state, produces the upwards thrust of jack-up.When air-conditioning normally moves, the thrust that spring 3 downward impacting forces make progress greater than air-conditioning, suction port 1-1 is in closed condition; When air conditioning pressure reaches opening pressure of safety valve, the thrust that to be air-conditioning make progress to spool 2 is during greater than the pressure of spring, make spool 2 by jack-up, the safety valve exhaust pressure relief, after the compressor internal pressure is discharged reduction, spool 2 is closed under the active force of spring 3 again, and the setting of cracking pressure can be followed according to the different pressure of spring and be adjusted.
Take above-mentioned foundation desirable embodiment of the present utility model as enlightenment, by above-mentioned description, the relevant staff can in the scope that does not depart from this model utility technological thought, carry out various change and modification fully.The technical scope of this model utility is not limited to the content on the specification, must determine its technical scope according to the claim scope.
