Embodiment Construction

[0051] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0052] Such as figure 2 As shown, the angle valve of the present invention includes an angle valve body 10, an angle valve spool 30 installed in the angle valve body 10, an anti-filling valve core 20 installed in the air inlet cavity of the angle valve body, a magnet A22 and Magnet B60.

[0053] The angle valve body 10 includes an air inlet 12 and an air outlet 11 arranged transversely and intersecting each other. The axis of the air outlet 11 intersects the axis of the air inlet 12 and defines a plane as the central plane of the angle valve.

[0054] The anti-filling spool 20 includes an upper valve body 23 and a lower valve body 24 that cooperate with each other, a sealing plate 21 that closes the venting path port of the spool, and a sealing plane that sets the venting path port and cooperates with the sealing surface of the sealing plate 21 (can ...

Abstract

The invention discloses an angle valve and a steel cylinder. The angle valve comprises an angle valve body, an angle valve core, a filling prevention valve core, a magnet A and a magnet B; the angle valve body comprises an air inlet and an air outlet; the filling prevention valve core comprises a sealing plate and a sealing plane matched with a sealing surface of the sealing plate; an included angle between the vertical line of the sealing plane and an angle valve center plane determined by the axis of the air outlet of the angle valve body and the axis of the air inlet of the angle valve body is between plus 20 degrees and minus 20 degrees; the magnet A is attached to the upper end of the back side of the sealing surface of the sealing plate; the magnet B is attached to the angle valve body or the filling prevention valve core; adjacent magnetic poles of the magnet B and the magnet A are located in two 120-degree fan sections formed by rotating the angle valve center plane along the axis of the air inlet of the angle valve by plus 60 degrees and minus 60 degrees, and are located in an angle valve body area within 20mm above and below the uppermost end of external threads of the air inlet of the angle valve body, or in a valve core structure opposite to the sealing plane; and the adjacent magnetic poles of the two magnets have the same polarity. The steel cylinder comprises a cylinder body and the angle valve which are mutually connected. The angle valve and the steel cylinder are high in cracking prevention ability, simple in structure and low in cost.

Description

technical field [0001] The invention relates to an angle valve capable of preventing others from filling gas, and also relates to a steel cylinder using the angle valve. Background technique [0002] Angle valves are valve components used in liquefied gas cylinders and other pressure vessel cylinders, and are crucial to ensuring the safety of pressure vessels. [0003] In order to realize the effective management of liquefied gas cylinders, prevent the abuse of liquefied gas cylinders, and improve the safety of use, angle valves have appeared. Such as figure 1 As shown, the angle valve includes an angle valve body 10, an angle valve spool 30 installed in the angle valve body 10, an anti-filling spool 20 installed in the cavity of the air inlet 12 of the angle valve body 10, the The anti-fill valve core 20 includes a sealing plate 21 that closes the port of its venting path, so as to prevent abuse of the liquefied gas cylinder. [0004] The anti-fill spool of the angle val...
