Description

A naked open pipe pinch valve

technical field

The utility model relates to a pipe pinch valve, in particular to a naked open type pipe pinch valve. the

Background technique

The metal valve body is used in traditional pipeline transportation. The metal valve body is easy to wear and has a low service life. At the same time, the valve body is an integrated structure, which is costly, frequent maintenance, and affects production. Maintenance and disassembly are troublesome and can only be replaced as a whole. the

Utility model content

Aiming at the defects of the traditional metal valve body being easy to wear and having a low service life, the technical problem to be solved by the utility model is to provide a bare open pipe pinch valve which is wear-resistant, has a long service life and is easy to maintain. the

In order to solve the above-mentioned technical problems, the technical solution adopted by the utility model is: a naked open pipe pinch valve, including an upper valve body, a lower valve body and a valve stem, the valve stem is provided with external threads, and the upper valve body is provided with There is an internal thread that matches the external thread on the valve stem. One side of the hose on the lower valve body is provided with an upper pressure rod. One end of the valve stem is in contact with the upper pressure rod. There is a support on the lower valve body. The other side of the rubber hose A lower pressing rod is provided, and guide rods are arranged at both ends of the lower pressing rod. The guide rod passes through the support and can slide on the support. The end of the guide rod is fixedly connected with the upper valve body. The upper pressing rod and the lower pressing rod form a clamping structure for the rubber hose. The other end of the valve stem is fixedly connected with a hand wheel. Grooves matching the guide rods are arranged at both ends of the upper pressing rod. The guide rod and the upper valve body are threaded. Turn the hand wheel, the hand wheel drives the valve stem to move downward, the valve stem pushes the upper pressing rod to move downward and the upper pressing rod moves upward, thereby clamping the rubber hose and closing the pipe. When the pipeline needs to be opened, the hand wheel is turned, and the upper pressing rod and the lower pressing rod are released. the

The utility model has the advantages that the split valve body is easy to disassemble during maintenance; the clip-on structure can ensure that there is no leakage when the rubber hose is pressed and the valve is closed, and can withstand greater medium pressure; different types of valves can be used. The rubber hose is wear-resistant and corrosion-resistant; it has a wide range of applications, and can be used for shutting down, opening and adjusting in low-pressure pipelines such as clean water, sewage, slurry, and oil. the

Detailed ways

Fig. 1 is a structural schematic diagram of a bare open pipe pinch valve of the present invention, comprising an upper valve body 1, a lower valve body 2 and a valve stem 6, the valve stem 6 is provided with an external thread, and the upper valve body 1 is provided with a The external thread on the valve stem 6 matches the internal thread, one side of the hose 7 on the lower valve body 2 is provided with an upper pressure rod 3, one end of the valve stem 6 is in contact with the upper pressure rod 3, and the lower valve body 2 is provided with a support 8. The other side of the rubber hose 7 is provided with a lower pressure rod 4, and the two ends of the lower pressure rod 4 are provided with a guide rod 5. The guide rod 5 passes through the support 8 and can slide on the support 8. The end of the guide rod 5 is connected to the The upper valve body 1 is fixedly connected, and the upper pressing rod 3 and the lower pressing rod 4 form a clamping structure to the rubber hose 7 . The other end of the valve stem 6 is fixedly connected with a hand wheel 9 . Grooves matching the guide rod 5 are provided at both ends of the upper pressing rod 3 . The guide rod 5 is threadedly connected with the upper valve body 1 . During use, turn the hand wheel 9, the hand wheel 9 drives the valve stem 6 to move downward, the valve stem 6 pushes the upper pressure rod 3 to move downward and the lower pressure rod 4 to move upward, thereby clamping the rubber hose 7 and sealing the pipeline. When the pipeline needs to be opened, the hand wheel 9 is turned, and the upper pressing rod 3 and the lower pressing rod 4 are released. the

The split valve body is used for easy disassembly during maintenance; the clip-on structure can ensure that there is no leakage when the hose is pressed together and the valve is closed, and can withstand large medium pressure; different types of hose can be used, which are wear-resistant and resistant Corrosion: It is applicable to a wide range of fields, and can be used for shutting down, opening and adjusting in low-pressure pipelines such as clean water, sewage, slurry, and oil. the

The utility model has been exemplarily described above in conjunction with the accompanying drawings. Obviously, the specific implementation of the utility model is not limited by the above-mentioned methods, as long as various insubstantial improvements are made by adopting the method concept and technical solutions of the utility model, or Those who directly apply the design and technical solutions of the utility model to other occasions without improvement are within the protection scope of the utility model. the
