Description

Technical Field

[0001] The utility model relates to the technical field of cut-off valve equipment, in particular to a two-way flow cut-off valve. Background Art

[0002] To facilitate the flow and shutoff control of fluids, a shutoff valve device is often required. The utility model patent application, CN201320384315.1, discloses a shutoff valve in which the piston and shutoff valve stem are separately arranged in the cylinder body, making the piston an independent component unit. A spring seat is also added. The structural design prevents air leakage at the pneumatic actuator, ensuring leak-free opening and closing of the shutoff valve, greatly improving the sealing performance of the shutoff valve. The material of the sealing ring at the valve core connection of the shutoff valve stem is changed to a polytetrafluoroethylene (PTFE) composite material with excellent wear resistance, heat resistance, compression strength, and creep resistance, and a temperature resistance of 350°C. The sealing surface of the sealing ring is changed to a spherical seal, which increases the reliability of the opening and closing of the shutoff valve and its pressure and temperature resistance. According to the disclosed technical solution, when the existing shutoff valve device is in use, on the one hand, when the power mechanism fails, the opening and shutoff control is often unable to be performed, reducing the reliability of the device. On the other hand, when the sealing mechanism in the valve core and the valve sleeve is worn, fluid leakage occurs, and the sealing effect after the shutoff is often unable to be guaranteed.

[0003] Therefore, how to design a two-way flow cut-off valve has become our current problem to be solved. Utility Model Content

The utility model has a reasonable design and is relatively convenient to use. It is suitable for two-way flow and cut-off use of fluids.

[0005] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: a two-way flow cut-off valve, comprising a valve sleeve and a valve core, connecting assemblies are installed at both ends of the valve sleeve, the connecting assembly comprises joint 1 and joint 2, a blocking assembly is installed on the inner side of the valve sleeve, the blocking assembly comprises a cone and a retaining ring, a connecting assembly is installed on the inner side of the valve core, the connecting assembly comprises an inner port and a through port, a control assembly is installed on the inner side of the connecting assembly, the control assembly comprises electromagnet 1 and electromagnet 2, a power-off assembly is installed on the inner side of joint 1, the power-off assembly comprises a slider and an electrode, a detection assembly is installed on the connecting assembly, and the detection assembly comprises a sensor and a display.

[0006] Furthermore, the first connector is sealingly mounted on one end of the valve sleeve, and the second connector is sealingly mounted on the other end of the valve sleeve.

[0007] Furthermore, a through cavity is opened on the inner side of the valve sleeve, the retaining ring is integrally formed on the inner side of the through cavity, the cone is opened in the middle of the valve core, the cone is located on the inner side of the retaining ring, the diameters on both sides of the cone are larger than the inner diameter of the retaining ring, and the inner diameter of the retaining ring is larger than the diameter of the middle part of the cone.

[0008] Furthermore, the inner ports are respectively opened on both sides of the valve core, the through ports are opened around the inner ports, and the through cavity is respectively connected to the first connector and the second connector through the through ports and the inner ports.

[0009] Furthermore, the electromagnet 1 is welded to the inner side of the joint 1, the electromagnet 2 is welded to the inner side of the joint 2, and the electromagnet 1 and the electromagnet 2 are respectively connected to the two sides of the valve core through the spring 1.

[0010] Furthermore, a slide groove is provided on the inner side of the first connector, the slider is clamped on the inner wall of one side of the slide groove, the electrode is welded to the inner wall of the slide groove, and the slider is pressed on the electrode.

When the two-way flow cut-off valve is in use, the equipment is connected to an external control switch group, and electromagnet 1 and electromagnet 2 are turned on by the control switch. After electromagnet 1 is energized, the slider is pulled to the left, so that the slider is separated from the electrode, so that electromagnet 2 will not open, avoiding the simultaneous opening of electromagnet 1 and electromagnet 2 due to human operating errors, thereby ensuring the closing of the two-way flow cut-off valve. Electromagnet 1 pulls the valve core to the right through spring 1, so that the cone is blocked on the left side of the retaining ring, thereby realizing the fluid cut-off. If electromagnet 1 fails, spring 2 pushes the slider to squeeze the electrode, and then opens electromagnet 2, so that the cone on the valve core is sealed on the right side of the retaining ring, so as to cut off both sides of the valve sleeve, which can effectively improve the reliability of the equipment.

If the left side of the retaining ring 7 and the left side of the cone 5 are worn, the electromagnet 1 8 is closed and the electromagnet 2 9 is opened to cut off the fluid, and the retaining ring 7 is sealed with the right side of the cone 5, thereby improving the sealing effect of the equipment, preventing leakage due to wear of the valve core 4 and the retaining ring 7, and ensuring the sealing effect of the two-way flow cut-off valve.

[0022] In this embodiment, a through cavity 6 is provided on the inner side of the valve sleeve 1, and the retaining ring 7 is integrally formed on the inner side of the through cavity 6.

After the electromagnet 1 8 is energized, the slider 13 is pulled to the left, so that the slider 13 is separated from the electrode 15, so that the electromagnet 2 9 will not be opened, thereby avoiding the simultaneous opening of the electromagnet 1 8 and the electromagnet 2 9 due to human operation errors, thereby ensuring the closing of the two-way flow cut-off valve. The electromagnet 1 8 pulls the valve core 4 to the right through the spring 10, so that the cone 5 is blocked on the left side of the retaining ring 7, thereby realizing the fluid cut-off work. If the electromagnet 1 8 fails, the spring 2 14 pushes the slider 13 to squeeze the electrode 1 5, and then open the electromagnet 2 9, so that the cone 5 on the valve core 4 is sealed on the right side of the retaining ring 7, so as to cut off the two sides of the valve sleeve 1, which can effectively improve the reliability of the equipment.
