Abstract
The utility model relates to a fast valve of closing especially relates to a dual-purpose pneumatic fast valve of closing. The utility model has the advantages that: the user rotates the rotating handle, and the rotating handle drives the connecting rod and the valve rod to rotate. The connecting rod and the valve rod can move along the threads when rotating, the valve core moves along with the valve rod, and the valve core can open or close the isolation cavity. But the speed of closing the case through the screw thread is slower, and this technical scheme can provide compressed air to the valve rod chamber through the air supply, and compressed air promotes the baffle and removes, makes valve rod and connecting rod break away from, and the case seals the isolation chamber fast, and later screw in is again made connecting rod and valve rod recovery to be connected.
Description
Technical Field
The utility model relates to a fast valve of closing especially relates to a dual-purpose pneumatic fast valve of closing.
Background
In a fuel conveying pipeline of a marine main engine, when an emergency occurs, a medium in the pipeline needs to be cut off quickly. There is a need for a valve that can be quickly closed to allow quick closing action to be achieved. The quick closing action is driven by compressed air available anywhere on a ship, the compressed air is efficient, energy-saving, reliable and environment-friendly, and remote control operation can be realized, so the valve is called a pneumatic quick closing valve for the ship, and is hereinafter referred to as a quick closing valve. The marine quick-closing valve needs to be capable of quickly closing the valve.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the technical problem that overcome exist among the prior art not enough, provide a dual-purpose pneumatic fast valve of closing.
The utility model discloses a realize through following technical scheme:
a dual-purpose pneumatic quick-closing valve comprises a valve body, a valve core, a valve rod and an air source, wherein the valve body comprises an upper valve body and a lower valve body which are fixedly connected, a valve cavity is arranged in the lower valve body and comprises a liquid inlet cavity, a liquid outlet cavity and an isolation cavity, the liquid inlet cavity, the isolation cavity and the liquid outlet cavity are sequentially communicated, the valve core is positioned in the isolation cavity, the valve core is fixedly connected with the valve rod, the isolation cavity is provided with a through hole, the valve rod penetrates through the through hole of the isolation cavity, the upper valve body is provided with a valve rod cavity, two ends of the valve rod cavity are provided with through holes, the valve rod penetrates through the through hole of the valve rod cavity and the valve rod cavity, the valve rod is provided with a blind hole, a connecting rod is inserted in the blind hole, the connecting rod is fixedly connected with a rotating handle, one through hole of the valve rod cavity is provided with an internal thread, the connecting rod is provided with an, the air pipe is connected with an air source.
According to above-mentioned technical scheme, preferably, the connecting rod is equipped with the hemisphere arch, is equipped with the recess with the protruding complex of hemisphere in the blind hole.
The utility model has the advantages that: the user rotates the rotating handle, and the rotating handle drives the connecting rod and the valve rod to rotate. The connecting rod and the valve rod can move along the threads when rotating, the valve core moves along with the valve rod, and the valve core can open or close the isolation cavity. But the speed of closing the case through the screw thread is slower, and this technical scheme can provide compressed air to the valve rod chamber through the air supply, and compressed air promotes the baffle and removes, makes valve rod and connecting rod break away from, and the case seals the isolation chamber fast, and later screw in is again made connecting rod and valve rod recovery to be connected.

The connecting rod and the valve rod can move along the threads when rotating, the valve core moves along with the valve rod, and the valve core can open or close the isolation cavity. But the speed of closing the case through the screw thread is slower, and this technical scheme can provide compressed air to the valve rod chamber through the air supply, and compressed air promotes the baffle and removes, makes valve rod and connecting rod break away from, and the case seals the isolation chamber fast, and later screw in is again made connecting rod and valve rod recovery to be connected.
According to the above embodiment, preferably, the connecting rod is provided with a hemispherical protrusion 15, and the blind hole is provided with a groove matched with the hemispherical protrusion. The connecting mode of the connecting rod and the valve rod can transmit torque and is convenient to connect and disconnect.
The utility model has the advantages that: the user rotates the rotating handle, and the rotating handle drives the connecting rod and the valve rod to rotate. The connecting rod and the valve rod can move along the threads when rotating, the valve core moves along with the valve rod, and the valve core can open or close the isolation cavity. But the speed of closing the case through the screw thread is slower, and this technical scheme can provide compressed air to the valve rod chamber through the air supply, and compressed air promotes the baffle and removes, makes valve rod and connecting rod break away from, and the case seals the isolation chamber fast, and later screw in is again made connecting rod and valve rod recovery to be connected.
