Description

Light duty rising rod pinch valve

technical field

The utility model relates to a pipe pinch valve, in particular to a light-type rising rod 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 light-duty rising rod pinch valve which is wear-resistant, has a long service life and is easy to maintain. the

In order to solve the above technical problems, the technical solution adopted by the utility model is: a light-duty rising rod pinch valve, including an upper valve body, a lower valve body and a valve stem. There is an internal thread that matches the external thread on the valve stem. One side of the rubber 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. A lower pressing rod is arranged on the side, 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. It also includes a casing for closing the light-duty rising rod pinch valve, and the casing includes an upper casing and a lower casing. 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. The upper shell and the lower shell are connected by bolts. 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; the upper shell and the lower shell can protect the valve body very well and achieve the effect of dust protection; it is widely used in low-pressure pipelines such as water purification, sewage, slurry, and oil. Off, On and Adjust are all available. the

Detailed ways

Figure 1 is a structural schematic diagram of a light-duty rising rod pinch valve of the present invention, including an upper valve body 1, a lower valve body 2 and a valve stem 6, the valve stem 6 is provided with external threads, and the upper valve body 1 is provided with The internal thread matched with the external thread on the valve stem 6, the upper pressure rod 3 is provided on one side of the rubber hose 7 on the lower valve body 2, 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 Seat 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 It is fixedly connected with the upper valve body 1, and the upper pressing rod 3 and the lower pressing rod 4 form a pair of rubber hoses 7 to form a clamping structure. It also includes a housing that closes the light-duty rising rod pinch valve, and the housing includes an upper housing 10 and a lower housing 11 . 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 . The upper casing 10 and the lower casing 11 are connected by bolts. 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; the upper shell and the lower shell can protect the valve body very well and achieve the effect of dust protection; the application field is wide, and the shut-off, opening and adjustment of low-pressure pipelines such as water purification, sewage, slurry, oil, etc. be usable. 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 Directly applying the ideas and technical solutions of the utility model to other occasions without improvement is within the protection scope of the utility model. the
