SPR-7R™ホルダー

性能

フランジのボルトサークル内に収まり、取り付け、取り外しが容易なインサートタイプのホルダー
プリアッセンブリー型によるコスト削減
J ボルトは、プロセス側フランジの外周に開けられた穴と接合することにより、ホルダーが必要な方向に確実に取り付けられるようにします
ホルダー内の位置決めピンが破裂板の位置決めホールと接合する事により、破裂板のセンタリングと正しい取付け方向を確保
セーフティヘッドの側面に刻印されているフロー矢印は、正しいフロー方向を示します
ホルダー内側座面に独自の「バイトシール」を施しており、破裂板とホルダーのプロセス側の間のシール性を最適化し、10^-6cc/s He 以上の気密性を実現
入口または出口のいずれかにオプションでタップ追加工が可能で、監視デバイスやセンサーの設置が可能
フランジ付き配管接続に使用。レイズドフェイス、リングジョイント、その他複数のフランジ定格および配管規格に対応した設計
ラプチャーディスクのドーム部は、配管システムに設置される際の損傷を避けるため、ホルダー内で完全に保護されています
延長アウトレット付きで、ディスク起動後でも簡単に取り外し可能
トルク耐性のあるバージョンも利用可能、SPR-7R-TR をご指定下さい

Accessories

BS&B supplies many of the accessories required to safely and conveniently install our overpressure relief devices and complementary products. Through our professional team and global network of sales engineers and procurement personnel, we are able to provide the highest quality accessory products to meet your installation requirements.

Saf-T-Change Quick Disk Replacement (QDR)

After activation, the replacement disk is quickly slid into place. Saving hours of lost production due to blown rupture disks.

Tell-Tale Assemblies & Excess Flow Valves/Gauges

A gauge tap in the outlet flange of the safety head may be considered when the safety head is installed in a vertical position.

Spare Safety Heads & Cap Screws

Jackscrews

When activated, the jackscrews effectively separate the flanges, providing adequate clearance to remove or insert a safety head and external gaskets.

Lifting Lug Eye Bolts

Eye bolts are recommended when weight and/or accessibility is a factor in lifting safety heads.

Baffle Plate

When a safety head is free-vented to atmosphere, a baffle plate may be considered to disperse overpressure and absorb recoil.
