Referring to fig. 1 to 3, fig. 1 to 3 are schematic structural diagrams of an easy-to-detach sampling valve according to an embodiment of the present utility model, as shown in fig. 1 to 3, the sampling valve includes a valve rod 10 and a valve body 20, the bottom of the valve rod 10 is vertically connected to the valve body 20 from above the valve body 20, and is connected to a valve core 201 inside the valve body 20, and the valve rod 10 drives the valve core 201 through rotation to control opening and closing of the valve body 20;
one side of the valve body 20, which is close to the valve rod, is detachably connected with the first conduit 30, the other side of the valve body 20, which corresponds to the position of the first conduit 30, is detachably connected with the second conduit 40, and a protruding structure is arranged on the outer wall of the second conduit 40.
It should be noted that, in this embodiment, the valve rod 10 and the valve body 20 can not only ensure the structure of sealing connection as shown in the figure, but also can be disassembled quickly and reliably based on the structure, the valve rod 10 and the valve body 20 adopt an access connection mode, and the valve body 20 and the first conduit 30 and the second conduit 40 adopt a detachable connection mode, specifically, the detachable connection mode can be in the form of threaded connection, screw connection or flange connection.
In use, the sampling valve according to the present embodiment is constructed by inserting the second conduit 40 into the medium to be sampled, then unscrewing the valve stem 10, forming a passage for the passage of the sample substance inside the valve body 20, and withdrawing the sample substance through the first conduit 30. In addition, the outer wall of the second conduit 40 in this embodiment is further provided with a protruding structure, which is used for ensuring that the second conduit 40 will not form an adhesive layer on the surface thereof when inserted into the viscous medium to be sampled, thereby protecting the sampling valve to a certain extent.
Further, in the embodiment of the present utility model, a rotatable handle 101 is fixedly disposed on the top of the valve rod 10, and the handle 101 drives the valve rod to rotate when being rotated, so as to control the opening and closing of the valve body. As shown in fig. 1-2, in practical use, it is generally inconvenient to directly rotate the valve rod 10, so this embodiment provides a fixed handle 101, and the handle 101 is not freely rotatable relative to the valve rod 10, that is, rotation of the handle 101 must cause rotation of the valve rod 10, so as to further actuate the valve core inside the valve body to control opening and closing of the valve body.
Further, in an embodiment of the present utility model, a threaded structure is provided on a side of the first conduit connected to the valve body, and a threaded structure is provided on an inner wall of the communication hole of the valve body connected to the first conduit, and the first conduit corresponds to the threaded structure of the valve body. It should be understood by those skilled in the art that the detachable connection of the two components by the screw thread is a common means, and thus, the description of the thread pattern and the like will not be repeated here.
Further, in the embodiment of the present utility model, a nut is installed on the screw structure of the first conduit 10, and an inner wall of the nut corresponds to the screw structure of the first conduit and abuts against a communication hole where the valve body is connected to the first conduit; and the nut limits the first conduit to the current connection when being tightened.
Through the design of the nut, the position of the first conduit can be limited at the current position, so that certain connection is still maintained when the sampling valve does not work. When the sampling valve is required to work, the opening and closing of the valve body can be freely controlled through the valve rod only by loosening the nut through a screwdriver.
Further, in another embodiment of the present utility model, the valve core is a cavity structure, and the cavity structure communicates the first conduit and the second conduit when the valve body is opened, so as to form a chamber for accommodating no passage of the sample.
It should be noted that, in order to simplify the structure of the sampling valve to the greatest extent, so that the valve core is as simple as possible during disassembly, in this embodiment, the valve core itself plays a role of a cavity in the valve body, and when the valve body is opened, the position of the valve core is aligned with the first conduit and the second conduit through the valve rod, so that a sample flows into the first conduit through the valve core after flowing through the second conduit, and is led out to the outside by the first conduit, thereby realizing sampling.
Further, in another embodiment of the present utility model, an annular sealing ring is arranged at a connection part of the valve rod vertically connected to the valve body, and the annular sealing ring is made of elastic corrosion-resistant material; the valve body is made of corrosion-resistant stainless steel, and a corrosion-resistant inert coating is arranged on the inner wall of the valve body.
It should be understood by those skilled in the art that, since the sampling valve is often used in highly corrosive and highly polluting environments, it should have a certain corrosion resistance, so in this embodiment, a corresponding annular sealing ring is disposed on a part of the sampling valve, which is susceptible to being corroded by pollutants, and the material of the annular sealing ring may be polytetrafluoroethylene, etc., the material of the valve body itself may be low-carbon stainless steel, and the inner wall coating may be an oxidation-resistant carbon coating, etc.
Further, in still another embodiment of the present utility model, an external tooth structure is provided on a side of the first conduit not connected to the valve body, for switching different types of interfaces.
The foregoing description is only of the preferred embodiments of the present utility model and is not intended to limit the scope of the utility model, and all equivalent structural changes made by the description of the present utility model and the accompanying drawings or direct/indirect application in other related technical fields are included in the scope of the utility model.
