There is no limit to creativity, and the instrument is invented. Today we introduce a national invention patent for authorization - a slip control dual core valve. The patent was filed by Cangzhou Yikeda Energy Saving Technology Co., Ltd. and was authorized to be announced on April 5, 2017.
Description
The invention relates to a valve, in particular to a slip control double core valve.
Background of the invention
In the factory for producing chemical raw materials, various reaction kettles are used to chemically polymerize chemical raw materials. The reaction kettle is equipped with various valves such as a feed valve and a discharge valve. These valves have only one valve core, and during use, It not only has to withstand the expansion and contraction forces of high temperature and high pressure, but also with the corrosion of chemical substances such as acid, alkali and salt. Therefore, the leakage of chemical raw materials due to valve damage often occurs, which not only seriously pollutes the environment, but also causes greater damage to the enterprise. Economic loss.
Summary of the invention
In order to solve the problem that the prior art valve is damaged and the leakage cannot be closed in time, the present invention aims to provide a slip control double core valve, which is provided with two valve cores, when one of the valve cores is damaged and leaks, as long as By enabling another spool, the valve can be closed without loss of chemical material leakage.
Figure is a schematic view of an assembly structure of an embodiment of the present invention
In order to achieve the above object, the present invention adopts the following technical solution; a slip control double core valve, characterized in that the slip control double core valve comprises a double spool valve body and a sliding double control valve handle, the double The valve body of the valve body has a tubular structure and is provided with a rotary valve core at both ends thereof, the rotary valve core is provided with a drive sleeve, and the sliding double control valve includes a valve handle sliding base frame and sliding a shifting valve seat and a clutch type valve stem connecting the sliding base frame to the outer wall of the double valve core valve and having a sliding rail, the sliding valve mounting the seat on the valve handle sliding base frame and Slidingly cooperate with the sliding rail, a valve stem sleeve is arranged on the top of the sliding valve seat, and the bottom and the top of the clutch valve stem are respectively provided with a spool driving head and a wheel type valve handle, and the spool is driven The head is sleeved in the valve sleeve and can slide up and down, and the spool drive head and the drive sleeve are clutched and rotatably engaged.
The preferred embodiment further has the following technical feature: the double valve core valve body cavity is provided with a pipe type valve port, the rotary valve core is installed at the end of the pipe type valve port and is provided with a positioning rotating shaft, and the positioning rotating shaft is from the pipeline The valve port is transversely penetrated to the outside of the double valve core valve body, and the drive sleeve is disposed at the end of the positioning shaft, and a mating flange or a docking screw is disposed at both ends of the double valve body.
The valve has a sliding frame and has a sliding structure on both sides thereof, and the sliding valve crosses the seat on the top of the valve handle sliding base, and the driving sleeve is disposed on the valve Slide the base ends. The sliding valve has a track card plate on both sides of the seat, the track card plate is matched with the sliding track, and the valve rod sleeve is disposed in the middle of the sliding valve seat and the bottom surface of the sliding valve seat The same.
A slip drive mechanism is disposed between the valve handle slip base and the slip valve seat, the slip drive mechanism includes a toothed slide and a slip runner, and the toothed slide is disposed on the slide rail On the side, the slip wheel is mounted on the track card and cooperates with the toothed track through the gear. The spool drive head has a non-circular structure, and the center of the drive sleeve is provided with a non-circular socket matched with the spool drive head.
A positioning slot and a latching pin are respectively disposed on the clutch valve stem and the valve stem sleeve, and the two ends of the latching pin are respectively provided with a card groove ball and a pull pin, the card groove ball and the positioning slot In cooperation, a latch spring is arranged in the middle of the slot latch. The clutch type valve stem is provided with a disengagement spring disposed between the wheel type valve stem and the valve stem sleeve.
In this embodiment, two valve cores are installed in the inner cavity of the double valve core valve. When the common valve core is damaged and the chemical material is leaked, the spare pipe can be cut off to prevent the waste from being completely wasteted. And the situation of polluting the environment. Therefore, the sliding control double-core valve has a reasonable structure and convenient operation, and can effectively improve the reliability of the valve.
