Title
(EN) VALVE CORE ASSEMBLY AND ELECTRONIC EXPANSION VALVE HAVING SAME
(FR) ENSEMBLE NOYAU DE SOUPAPE ET SOUPAPE D'EXPANSION ÉLECTRONIQUE LE COMPRENANT
(ZH) 阀芯组件及具有其的电子膨胀阀
Abstract
(EN)
A valve core assembly, comprising a screw rod (10) and an annular structure (20). The annular structure (20) is a bushing or bearing; the screw rod (10) is of an integrally formed structure; the screw rod (10) comprises a first rod section (11) and a flange structure (12) disposed on one end of the first rod section (11); the radial dimension of the flange structure (12) is greater than the radial dimension of the first rod section (11); the first rod section (11) passes through the annular structure (20), and there is a gap between the circumferential surface of the first rod section (11) and the inner wall of the annular structure (20); the flange structure (12) is in limiting fit with one end of the annular structure (20).
(FR)
Ensemble noyau de soupape, comprenant une tige de vis (10) et une structure annulaire (20). La structure annulaire (20) est une douille ou un palier ; la structure de la tige de vis (10) est formée d'un seul tenant ; la tige de vis (10) comprend une première section de tige (11) et une structure de bride (12) disposée sur une extrémité de la première section de tige (11) ; la dimension radiale de la structure de bride (12) est supérieure à la dimension radiale de la première section de tige (11) ; la première section de tige (11) passe à travers la structure annulaire (20), et il existe un espace entre la surface circonférentielle de la première section de tige (11) et la paroi interne de la structure annulaire (20) ; la structure de bride (12) est en ajustement de limitation avec une extrémité de la structure annulaire (20).
