APPARATUS FOR CONDUCTING HYDRAULIC PROOF TEST

The invention relates to hydraulic proof-test apparatus comprising at least a valve (1) with parallel seats (102), and comprising: - a shut-off member (2) with parallel plates (20, 21) which are connected by connecting means for regulating their separation, to cause them to pass from a first positio...

Beschreibung
Zusammenfassung:	The invention relates to hydraulic proof-test apparatus comprising at least a valve (1) with parallel seats (102), and comprising: - a shut-off member (2) with parallel plates (20, 21) which are connected by connecting means for regulating their separation, to cause them to pass from a first position in which this separation is enough to allow the shut-off member (2) to be introduced into said valve (1) to a second position in which said separation is greater, this separation allowing them to be pressed firmly against said parallel seats (102); - a device (3) for inserting said shut-off member (2) into said valve (1) which comprises at least a U-shaped tool configured to be introduced into said valve (1), with its parallel arms forming guides, while its base forms a support for holding said shut-off member (2); - a "dummy stem" (4). 本发明涉及一种液压验证试验装置，其至少包括具有平行阀座(102)的阀(1)，并且包括：封闭构件(2)，其具有平行板(20，21)，这些板通过连接装置连接以调节其间距，从而使其从第一位置移动到第二位置，在第一位置，该间距足以使封闭构件(2)能够引入到所述阀(1)中，在第二位置，所述间距更大，该间距使得能够将它们牢固地压靠在所述平行阀座(102)上；用于将所述
