Example Embodiment

[0017] Such as figure 2 Shown is a schematic diagram of the structure of the present invention.

[0018] Such as figure 2 As shown, the valve of the present invention includes a valve housing 1 made of non-magnetic materials, and a valve connector 2 is screwed on the gas inlet end of the valve housing 1. A magnetic core controller 5 is connected to the outer casing of the valve housing. The valve connector 2 and the valve housing 1 are screwed together with an internal thread, and the gas inlet end of the valve housing 1 is provided with a matching external thread. The connection head has a first outward end surface 21 and a gas inlet end facing the valve housing. The second end surface 22 of the end.

[0019] According to the airflow direction, a positioning spring 9, a magnetic core 8, a sealing sheet 6 and a valve opening spring 7 are arranged in the valve cavity in sequence. The valve cavity is also provided with a positioning ring 12 near the valve joint, and a reset magne...

Abstract

The invention discloses a push-type multifunctional overflow-preventing fuel gas safety valve. The valve comprises a valve casing and a valve joint, wherein the valve casing is made of a non-magnetized material; a magnetic core controller is arranged outside the valve casing; a magnetic core is arranged in a valve cavity; the valve joint is connected to the gas inlet end of the valve casing; the internal cavity of the valve joint is provided with an ultra-flow protective valve for controlling the on-off state of gas flow at the gas inlet end of the valve cavity; the ultra-flow protective valve is provided with a sealing piece for controlling the on-off state of the gas flow; and the sealing piece is provided with a head part which protrudes outward. The push-type multifunctional overflow-preventing fuel gas safety valve is characterized in that: a return magnetic ring is also arranged in the valve cavity and can be controlled by the magnetic pole of the magnetic core controller to move and push the head part of the sealing piece which is in a closed state, so that the ultra-flow protective valve is opened. The push-type multifunctional overflow-preventing fuel gas safety valve has the advantages of capability of causing the return magnetic ring to act by the manual magnetic core controller so as to remove the overflow protection state of the ultra-flow protective valve, fast and accurate return, safe use and high durability.

Description

technical field [0001] The invention relates to a gas valve, in particular to a non-leakage permanent magnet drive valve with functions of overcurrent protection and overpressure protection. Background technique [0002] An existing permanent magnet drive valve for gas pipelines has a built-in overflow protection valve at the valve joint for controlling the on-off of the gas flow of the valve at the gas inflow end. Such as figure 1 As shown, the valve casing of the permanent magnet drive valve is connected to a valve joint at the gas inflow end, and an over-flow protection valve is arranged inside the valve joint. The over-flow protection valve is composed of a valve body, a valve stem, a valve stem bracket and a pressure spring. The shaft center of the valve stem support 34' is provided with a perforation, and the valve stem 31' passes through the hole and can move up and down along the axis. The valve stem 31' is provided with a cap 35' at the tail end, and the cap 35' i...
