Description
Technical field
The utility model relates to the control valve that a kind of variable compressor refrigeration agent discharge capacity is regulated.
Background technique
Control valve depends on Flow characteristics and control characteristic to the adjusting function of refrigeration agent discharge capacity.The technical order of weighing the control valve control characteristic is pilot pressure, and the stability of pilot pressure directly affects the compressor cooling effect, therefore, makes great efforts to improve the stable most important of control valve pilot pressure.
During control valve work, after the friction of not considering between the moving element, the perpendicularity of bellows component is to cause the unsettled main cause of pilot pressure, and this ripple assembly is vacuum ripple assembly, and its welding process is finished under vacuum state, guarantee certain degree of vacuum, vacuum chamber can not be excessive, in the ripple assembly spring arranged simultaneously, and spring is compressed during welding, reaction force is very large, and this perpendicularity to the ripple components welding guarantees to be difficult to.The postwelding visual inspection, great majority are distortion or crooked column, and such ripple assembly is packed in the valve, and its displacement must be nonlinear under the effect of power, and the non-linear of displacement must cause power--placement property non-linear.Need revise the ripple assembly for this reason, guarantee that assembling is vertical.
The model utility content
The purpose of this utility model provides the control valve that a kind of variable compressor refrigeration agent discharge capacity is regulated, to overcome present prior art above shortcomings.
The purpose of this utility model is to be achieved through the following technical solutions:
The control valve that a kind of variable compressor refrigeration agent discharge capacity is regulated, comprise housing and valve body, described valve body is arranged on the inner walls, make it to form a space, be respectively equipped with two O shape rubber seal on the outer wall of housing and valve body, be provided with bellows component in the space that forms between housing and the valve body, the bottom of bellows component is provided with top cover, the external cylindrical surface of top cover is provided with jump ring, jump ring is with this outer cylinder location, and the inside of valve body is provided with push rod, and the middle part of push rod is provided with spring, the push rod below is provided with the ball seat assembly, and ball seat assembly below is provided with filter screen.
Further, described jump ring comprises base and some fins, and the fin bottom is fixed on the excircle of base, and the fin top is provided with a punching projection, and the hole on punching point projection and the inner walls leans.
The beneficial effects of the utility model are: increase jump ring at the ripple assembly, jump ring is the top cover external diameter location with ripple assembly bottom, to guarantee that jump ring is concentric with the ripple assembly, jump ring is inboard to contact with ripple assembly external diameter, to revise ripple assembly cylinder bending, there are three punching point projections in the jump ring outside, and these three punching point projections contact with the control valve valve block internal diameter, guaranteeing ripple assembly working force--displacement is linear, thereby has improved the stability of control valve pilot pressure.
