Embodiment Construction

[0017] like figure 1 As shown, a self-sealing high-pressure valve of the present invention is mainly composed of a valve body 1 , a valve core 6 , a valve stem 15 and a valve cover 14 . A sealing ring 7 is installed between the valve cover 14 and the valve body 1, and is fixed by a gasket 8 and a screw 9. The spool 6 has a balance hole 6, the spool 6 is installed on the valve stem 15, the valve stem 15 is sealed by the packing 12, the upper end of the packing 12 is pressed by the packing gland 10 and the collar 11, and the lower end of the packing 12 is passed by the stuffing box ring 13 is compressed, and the stuffing box ring 13 is compressed by the valve core automatic sealing device.

[0018] The upper end of the valve body 1 and the valve seat 4 are provided with grooves, and each groove is equipped with an automatic sealing device for the valve cover and an automatic sealing device for the valve interface. The inlet and outlet of the high-pressure valve are equipped wi...

Abstract

The invention provides an automatic sealing high-pressure valve, which mainly includes an automatic sealing device for a valve stem, an automatic sealing device for a valve cover and an automatic sealing device for a valve interface. It is characterized in that the automatic sealing device is composed of a bonnet guide groove, a pressure block and an elastic damping ring of the pressure block, and the automatic sealing device of the bonnet is composed of a guide sleeve, a guide sleeve and a pressure ring of the valve body, an elastic damping ring under the guide sleeve, The elastic damping ring of the guide sleeve, the sealing ring, the elastic damping ring on the guide sleeve, the guide sleeve and the valve cover pressure ring are composed. The automatic sealing device of the valve interface is composed of the inlet bottom buffer pad, the inlet upper end buffer pad, the outlet upper end buffer pad and the outlet Bottom cushioning pad composition. The invention respectively realizes the automatic sealing of the valve stem, the valve stem and the valve inlet and outlet through the valve core automatic sealing device, the valve cover automatic sealing device and the valve interface automatic sealing device. The elastic damping ring in each device has the functions of gap adjustment, element protection and primary sealing.

Description

technical field [0001] The invention relates to a self-sealing high-pressure valve, in particular to an automatic sealing of a valve stem through a bonnet guide groove, a pressure block and an elastic damping ring, and through a guide sleeve, a pressure ring, an elastic damping ring and a sealing ring. The automatic sealing of the valve cover realizes the automatic sealing of the valve interface and the buffering function of the high-pressure fluid through the buffer pads at the inlet and outlet of the valve, and belongs to the technical field of high-pressure valve sealing. Background technique [0002] At present, high-pressure technology has been widely used in superhard material manufacturing, chemical industry, petrochemical industry and other fields. Valves are one of the important components in high-pressure systems. The reliability, safety, work efficiency and service life of valves directly affect the work of the entire system. . The ultra-high internal pressure in...
