Abstract
The invention discloses an automobile refrigeration air conditioning valve element, which comprises a control valve seat, a valve seat, a pipe wall sealing ring, a valve element seat, a valve element rod, a resetting spring and an elastic sealing ring, wherein the valve element rod is sleeved in an inner hole of the resetting spring and an inner hole of the valve seat, and is fixed in a mandrel screw hole of the valve element seat by external threads at the lower end of the valve element rod; and the elastic sealing ring is arranged between the upper end face of a sealing shaft step of the valve element seat and the sealing surface of the valve seat. The automobile refrigeration air conditioning valve element with the structure is low in machining requirement and reliable in sealing performance; and the elastic sealing ring can ensure axial seal between the valve element seat and the valve seat under the action of the resetting spring.
Description
Technical field
The present invention relates to refrigerated air-conditioning system, relate in particular to automobile refrigerating air-conditioning gas circuit spool.
Background technique
In the automobile refrigerating air-conditioning, all gas path control valve must be arranged, otherwise just can't just can't proper functioning to car air conditioner.Mostly existing automobile refrigerating air-conditioning spool is for being shape metallic leak-proof structure; Therefore very high to the processing request of valve pocket and spool, especially the processing request of sealing surface is higher, and the yield rate of product is not high; The physical dimension that adds upper valve sleeve and spool part is all very little, and difficulty of processing is big.
Summary of the invention
The purpose of this invention is to provide a kind of automobile tire qi of chong channel ascending adversely spool.
The technological scheme that the present invention takes is:
A kind of automobile refrigerating air-conditioning spool comprises control valve seat, valve seat, tube wall seal ring, valve core case, valve core rod and Returnning spring, is provided with internal thread at the endoporus epimere of control valve seat; Said valve seat is an axle sleeve structure, and the section cylindrical is provided with the outside thread that matches with the control valve seat internal thread above that, on the cylindrical of middle and lower part, is provided with guide ring and seal groove; The lower end surface is a sealing surface; Upper end at valve core rod is provided with limited step, and hypomere is provided with screw thread, and valve core rod is sleeved in the endoporus and valve seat endoporus of Returnning spring; On valve core case, be provided with seal shaft rank and core bar screw; The core bar screw is arranged on the center on seal shaft rank, and valve core rod is rotated with in the core bar screw of valve core case through the outside thread of its lower end, it is characterized in that: between the sealing surface of the upper-end surface on the seal shaft rank of valve core case and valve seat, be provided with elastic seal ring.
Further, said elastic seal ring is a rectangular seal.
Owing between the sealing surface of the upper-end surface on the seal shaft rank of valve core case and valve seat, be provided with elastic seal ring; Like this; Under the effect of Returnning spring; Elastic seal ring can be guaranteed axial seal between valve core case and the valve seat, and can reduce significantly the requirement on machining accuracy of the lower end sealing surface of the upper-end surface on the seal shaft rank of valve core case and valve seat.
