Abstract:
(EN) Disclosed is a valve (100), comprising a valve body (10), an inner valve seat (60) and a valve core (21). The valve core (21) is mounted in the valve body (10). The inner valve seat (60) is mounted in the valve body (10). The inner valve seat (60) has a ring-shaped main body (601) and a seal structure (604) extending inwards from an inner circumferential face of the ring-shaped main body (601), wherein the seal structure (604) is arranged in such a manner that the seal structure (604) seals a gap formed among the valve body (10), the inner valve seat (60) and the valve core (21) when the valve (100) is in a closed state. After the valve is used for discharging liquid, the amount of liquid residue inside the valve can be greatly reduced.
(FR) L'invention concerne une soupape (100) comprenant un corps (10) de soupape, un siège (60) de soupape interne et une partie centrale (21) de soupape. La partie centrale (21) de soupape est montée à l'intérieur du corps (10) de soupape. Le siège (60) de soupape interne est monté dans le corps (10) de soupape. Le siège (60) de soupape interne comporte un corps principal en forme d'anneau (601) et une structure d'étanchéité (604) s'étendant vers l'intérieur à partir d'une face circonférentielle interne du corps principal en forme d'anneau (601), la structure d'étanchéité (604) est disposée de telle sorte que la structure d'étanchéité (604) ferme hermétiquement un espace formé entre le corps (10) de soupape, le siège (60) de soupape interne et la partie centrale (21) de soupape lorsque la soupape (100) est dans un état fermé. Après que la soupape a été utilisée pour évacuer un liquide, la quantité de résidu liquide se trouvant à l'intérieur de la soupape peut être fortement réduite.
(ZH) 一种阀门(100),包括阀体(10)、内阀座(60)和阀芯(21),阀芯(21)安装于阀体(10)内,内阀座(60)安装于阀体(10)内。内阀座(60)具有环形主体(601)和从环形主体(601)的内周面向内延伸出的密封结构(604),其中密封结构(604)设置成当阀门(100)处于关闭状态时,密封结构(604)对阀体(10)、内阀座(60)以及阀芯(21)之间所形成的间隙进行密封。该阀门在用于排放液体之后,液体残留在阀门内部的量能够大大减少。
