Specific embodiment
In order to keep the present invention more obvious and easy to understand, the present invention is done furtherly below in conjunction with the drawings and specific embodiments
It is bright.
As shown in Fig. 1 and Fig. 2 combination, test of the invention blind flange 1 includes blind flange ontology 101 and positioning guide column
102, which is arranged in 101 lower end of blind flange ontology and one is made.101 lower end of blind flange ontology is provided with
Gasket annular groove 103, i.e. gasket annular groove 103 are located at blind flange ontology 101 and positioning guide column 102 in-between.
As shown in Fig. 3 and Fig. 4 combination, the preventer assembly method equipped with test blind flange of the invention is as follows:
It allows the positioning guide column 102 in test blind flange 1 to enter the passing hole of preventer 3 first, passes through positioning and guiding
Column 102 makes the gasket annular groove 103 on test blind flange 1 accurately with metal sealing cushion ring 2 to being just bonded, and effectively prevent pressing
Bad gasket ring groove face and metal sealing cushion ring.
Wherein, positioning guide column 102 is equipped with the chamfering increased, for example, 40 × 45 °, facilitate positioning guide column 102 to enter
In the passing hole of preventer 3.Gap between positioning guide column 102 and the passing hole of preventer 3 is 0.5-1mm.
