Description
Technical Field
The utility model belongs to the technical field of valves, and particularly relates to a valve with a fastening function.
Background
Valves are plumbing accessories used to open and close a pipe, control flow direction, regulate and control parameters of the transport medium (temperature, pressure and flow). The valve is a control part in a pipeline fluid conveying system, is used for changing the section of a passage and the flowing direction of a medium, and has the functions of diversion, cut-off, throttling, check, flow splitting, overflow pressure relief and the like. The valve generally comprises a valve body, water inlets and water outlets are arranged at two ends of the valve body, a valve cavity is arranged in the middle of the valve body, a valve core is arranged in the valve cavity, a valve rod is connected to the valve core, the valve rod penetrates through the valve cavity and is connected with a handle, and the handle drives the valve core to rotate, so that the on-off of the valve body is controlled. The valve body passes through the link connecting line of both sides, and the link is the interface of in-band/external screw thread usually, through the nut fastening, and general nut fastening needs specialized tool to lock, and the installation is very inconvenient, and uses the back for a long time, and the locking effect of nut can the variation, influences the leakproofness of valve.
Disclosure of Invention
The utility model aims to provide a valve with a fastening function, which is simple in structure and convenient to install.
Therefore, the technical scheme of the utility model is as follows: a valve with a fastening function comprises a valve body, a valve core, a valve rod and a handle, wherein the valve core is arranged in the valve body and is rotationally connected with the valve body; one end of the valve rod is fixedly connected with the valve core, the other end of the valve rod is connected with the handle, and the handle drives the valve core to rotate;
the method is characterized in that: the two sides of the valve body are provided with connecting ends, the connecting ends are provided with external thread structures, the interior of the valve body is provided with a fastening sleeve and a clamping sleeve, the fastening sleeve is of a tubular structure, one end of the fastening sleeve is inserted into the connecting ends, the other end of the fastening sleeve is provided with a convex annular surface, and the outer circumference of the fastening sleeve is provided with a convex clamping ring; the cutting sleeve is of a tubular structure, a notch is formed in the cutting sleeve, and the cutting sleeve is inserted into the fastening sleeve; the locking piece is of a hollow structure, an internal thread structure is arranged in the locking piece, and the locking piece is fixedly connected with the connecting end through threads; and a plurality of reinforcing ribs which are uniformly distributed are arranged on the outer circumference of the locking piece.
During the installation, insert the cutting ferrule with the plastic tubing, fill in the clamping sleeve again the cutting ferrule in the fastening sleeve, breach on the cutting ferrule is closed, tightly hoops the plastic tubing, fills in the link of valve body with the adapter sleeve again in, the snap ring in the adapter sleeve outside can increase the frictional force of adapter sleeve and link inner wall, overlaps the retaining member in the link outside at last, screws up fixedly, handle when retaining member outside evenly distributed's strengthening rib can act as rotatory retaining member need not other instruments, can screw up the retaining member.
The utility model utilizes the fastening sleeve and the clamping sleeve to increase the sealing performance between the valve and the pipeline, and utilizes the reinforcing ribs on the outer side of the locking part to serve as handles when the locking part is rotated, so that the pipeline can be easily locked, and the installation process of the valve is completed.
