Description
Technical field
Patent of the present invention is related to gas compressor technical field, specifically a kind of to be applied to prevent gas compressor cylinder
The cylinder cover structure of liquid hammer.
Background technology
The generation of the liquid hammer of gas compressor is produced in the cylinder because of gas compressor or into liquid, because liquid has
There is Incoercibility so that pressure drastically raises in the volume space between cylinder cap and piston, causes compressor being compressed
During stress become big, when pressure exceedes the ability to bear of exhaust valve component so that exhaust valve component connects with its setting element
The fracture of relay part, cause the damage of air bleeding valve, and then damage the first-class stressed member of piston rod, cross of compressor, cause tight
The liquid hammer accident of weight, makes compressor cisco unity malfunction, or even scrap, and causes the loss that can not be retrieved and equipment investment expense
Improve, waste of resource.Therefore, it is imperative to develop the refrigeration compressor with liquid impact prevention function.
The content of the invention
It is an object of the invention to provide a kind of cylinder cover structure for being applied to prevent gas compressor cylinder liquid hammer.
The technical scheme is that：An arch cavity is provided with cylinder cap, is divided in two arch surfaces of arch cavity
A relief hole and an air admission hole are not provided with, a pressure release seal sleeve is provided with relief hole, and air inlet position is provided with
One air inlet sleeve with O-ring seals；A spring spindle, the bullet are provided between pressure release seal sleeve and air inlet sleeve
Air inlet sleeve is inserted in one end of spring push rod after passing through spring, and the other end is withstood on pressure release seal sleeve, pressure release seal sleeve and bullet
The joint face of spring push rod is the conical surface；A circle steam vent is provided with the air inlet sleeve, inserts one on a steam vent wherein
Individual alignment pin；A pressure transmitter is additionally provided with the outer wall of arch cavity.
The spring spindle that in coniform sealing ring, is connected with pressure release seal sleeve is formed with the inwall of pressure release seal sleeve
End and the coniform sealing ring of pressure release seal sleeve inwall mutually agree with.
The outside of air inlet sleeve is provided with air inlet articulation.
A circle steam vent in the air inlet sleeve is radial arrangement.
The relief hole is the inscribed circle of the arc of arch surface.
It is an advantage of the invention that when producing hydrops in gas compressor cylinder, stress becomes big at cylinder cap, and top is opened on cylinder cap
The spring spindle of setting, the pressure of separate chamber in cylinder cap is set to produce obvious fluctuating change, it is only eventually through cylinder cap is arranged on
Pressure transmitter on vertical chamber is alarmed to trigger, and the alignment pin being only fixed in steam vent in whole process is destroyed,
Damage of the liquid hammer to compressor associated components is avoided, the present invention also has the spies such as simple in construction, easy to operate, reliability is high
Point.
Brief description of the drawings
Fig. 1 is the external structure simplified schematic diagram of the present invention.
Fig. 2 is Fig. 1 sectional view.
Embodiment
Embodiment 1
Referring to Fig. 1 ~ 2, an arch cavity is provided with cylinder cap 7, is respectively arranged with two arch surfaces of arch cavity
One relief hole and an air admission hole, a pressure release seal sleeve 6 is provided with relief hole, and air inlet position is provided with a band O
The air inlet sleeve 3 of shape sealing ring；A spring spindle 4, the spring top are provided between pressure release seal sleeve and air inlet sleeve
Air inlet sleeve is inserted in one end of bar after passing through spring, and the other end is withstood on pressure release seal sleeve, pressure release seal sleeve and spring top
The joint face of bar is the conical surface；A circle steam vent is provided with the air inlet sleeve, one is inserted on a steam vent wherein and is determined
Position pin 8；A pressure transmitter 1 is additionally provided with the outer wall of arch cavity.
It is formed with the inwall of pressure release seal sleeve in coniform sealing ring 5, the spring spindle being connected with pressure release seal sleeve
End and the coniform sealing ring of pressure release seal sleeve inwall mutually agree with.
The outside of air inlet sleeve is provided with air inlet articulation 2.
A circle steam vent in the air inlet sleeve is radial arrangement.
The relief hole is the inscribed circle of the arc of arch surface.
In use, being passed through the gas in respective stages exhausting buffer to arch cavity by air inlet articulation, make gas
With on spring spindle, so that one end of spring spindle is pressed on pressure release seal sleeve, stablize relatively so as to obtain one
Pressure environment.
Nominal situation lower spring push rod be subject to the right gas force (by be filled with gas provide) with spring make a concerted effort just
Gas force (as caused by the piston movement in the cylinder body chamber gas force, therefore bullet to the left that can balance that spring spindle is subject to
Spring is in order to offset the pressure differential as caused by cylinder to respective stages exhausting buffer crushing, in order to avoid triggered under causing nominal situation
Warning device.
When producing liquid in gas compressor cylinder or to have liquid to enter fashionable, due to the Incoercibility of liquid, cylinder body exists
The pressure moment acted in reciprocating motion on piston becomes big, and pressure reversal push the spring push rod, spring spindle is in pressure moment
The alignment pin of insertion steam vent is struck off in the case of increase, and is moved into air inlet sleeve, band spring spindle closure steam vent；Together
Shi Yinwei spring spindles move into air inlet sleeve so that and spring spindle disengages with alarm sleeve, cylinder cap compartment and cylinder body UNICOM,
So as to cause the pressure in cylinder head compartment drastically to change；Finally by the pressure transmitter on cylinder cap end face according to pressure
The change of power carries out sound and light alarm.
