Problems solved by technology

[0002] In the prior art, the stop valve generally adopts the plunger type opening and closing form, especially when it is applied in the field of high-temperature liquid metal casting production below 500 °C, although the stop valve can play a cut-off effect after closing the stop valve, the shaft hole matching There are still gaps, liquid metal is easy to infiltrate and solidify, block the stop valve, which is not conducive to opening again, and repeated opening and closing in the blocked state will easily cause damage to the internal components of the stop valve, reduce the service life of the stop valve, and increase the replacement frequency of the stop valve ,increase cost

Abstract

The invention discloses a high-temperature-resistant pneumatic check valve, and relates to a check valve. An ingot valve body is a straight tee pipe fitting. Two ends of a main pipe are an inlet end and a connecting end respectively. A branch pipe end is an outlet end. One end of a valve body end cover is fixedly connected with a connecting end of an ingot valve body. A first tin bronze bushing isfixed to one end of the interior of the valve body end cover in a clamping manner. A second tin bronze bushing is fixedly connected to the other end of the valve body end cover. Both a graphite asbestos gasket and a spring are arranged inside the valve body end cover. The middle portion of a valve pin is arranged in an end cover assembly in a sealed sliding manner. An inlet end of the ingot valvebody can be blocked by a free end of the valve pin. A connecting end of the valve pin is detachably fixed to one end of a heat dissipation connecting rod. A copper cooling fin group is fixedly arranged on the heat dissipation connecting rod. An outer end of a gas cylinder piston rod is detachably fixed to the other end of the heat dissipation connecting rod through a connecting piece. A gas cylinder shell is fixedly connected with the valve body end cover through an installation rack. A heating wire is arranged on the outer side of the ingot valve body in a winding manner. Adverse impact caused by liquid metal solidification blocking is reduced, and the service life is prolonged.

Description

technical field [0001] The invention relates to a shut-off valve, in particular to a high-temperature-resistant pneumatic shut-off valve. Background technique [0002] In the prior art, the stop valve generally adopts the plunger type opening and closing form, especially when it is applied in the field of high-temperature liquid metal casting production below 500 °C, although the stop valve can play a cut-off effect after closing the stop valve, the gap between the shaft and hole matching There are still gaps, liquid metal is easy to infiltrate and solidify, blocking the stop valve, which is not conducive to opening again, and repeated opening and closing in the blocked state is easy to cause damage to the internal components of the stop valve, reducing the service life of the stop valve and increasing the replacement frequency of the stop valve ,increase cost. [0003] Therefore, it is necessary to design a reasonable and effective cut-off valve that can reduce the adverse...
