Abstract
The utility model discloses an air inlet valve for a liquefied gas compressor. The air inlet valve comprises an overflow cover arranged above a valve seat, wherein an overflow spring and an overflow valve ball are arranged in the overflow cover; an overflow cover body is provided with an overflow port; an external thread is formed in the circumferential direction of an overflow joint on the valve seat; and the overflow cover is in threaded fit connection with the overflow joint on the valve seat. Compared with the prior art, the air inlet valve has the beneficial effects that: the overflow cover is in threaded fit connection with the valve seat, disassembly and assembly in a use process are very convenient, and the problems the use of a bonding agent and easiness in damaging the overflow cover existing in the conventional structure are solved.
Description
Technical field
The utility model relates to the liquefied gases compressor field, exactly is a kind of liquefied gases compressor suction valve.
Background technique
The upper end of liquefied gases compressor suction valve need be provided with overflow mechanism, is used for regulating automatically suction pressure, plays the off-load effect; The overflowing hood structure of existing liquefied gases compressor suction valve is the drum shape housing that inwardly slightly closes up in the lower end, and adopts adhesive bonds to fix between the valve seat, and is cumbersome when this structure is used; When residual slag need clean in the overflowing hood, must the abutting edge be pried open, both wasted time and energy; Damage the bonding mouth of overflowing hood again easily; Must use adhesive bonds again after the cleaning, operate very inconvenience in the real work, and increase user cost.
The model utility content:
To the deficiency that existing liquefied gases compressor suction valve exists, the purpose of the utility model is to provide a kind of liquefied gases compressor suction valve of overflowing hood easy accessibility.
The purpose of the utility model is achieved through following technological scheme:
The liquefied gases compressor suction valve; Comprise the overflowing hood that the valve seat top is provided with; Be provided with overflow spring and overflow valve ball in the said overflowing hood; The overflow cover body is provided with flow-off, it is characterized in that: on the said valve seat overflow adapter be circumferentially with outside thread, the overflow joint screw thread is connected on said overflowing hood and the valve seat.
The utility model compared with prior art has following beneficial effect: overflowing hood and valve seat adopt screw-thread fit to be connected, in the using process dismounting very convenient, solved existing structure use binder and the flimsy problem of overflowing hood.
Description of drawings
Fig. 1 is the utility model example structure schematic representation.
