Novel sealing regulating valve device

Abstract

The invention relates to a regulating valve device, in particular to a novel sealing regulating valve device used for regulating vacuum degree of an extruder. The novel sealing regulating valve device comprises a pressure-regulating valve cover 1, a pressure-regulating valve body 5, a taper spool 7 and pressure-regulating valve bases. The pressure-regulating valve cover 1 is in an inverted concave shape and fixedly connected with a long shaft and a round nut 2; the upper portion of the pressure-regulating valve body 5 is a hollow cylinder, and the lower portion of the same is inwardly concave with a cone surface convex-shaped; small holes are longitudinally formed around a convex-shaped upper top and horizontally penetrate the side wall of the pressure-regulating valve body 5, the long shaft penetrates the pressure-regulating valve body 5, and a square nut 4 and a spring 6 are arranged on the long shaft of a hollow cylindrical cavity formed in the upper portion of the pressure-regulating valve body 5; the taper spool 7 is arranged at the lower end of the long shaft; the pressure-regulating valve bases include the pressure-regulating valve base A8 and a pressure-regulating valve base A10, and the pressure-regulating valve base A10 is sleeved on the pressure-regulating valve base A8 and fixedly connected with the same; the taper spool 7 is arranged inside the cone surface convex-shaped lower portion of the pressure-regulating valve body 5 and overlapped to be sealed with the same; the taper spool 7 is coaxially arranged with the long shaft and fixed through a hexagon nut 9. The novel sealing regulating valve device is simple and reasonable in structure and capable of being used in the various extruders with requirements on the vacuum degree; the problem of difficulty in regulating the vacuum degree of extrusion production equipment by operating personnel is solved, time is saved and labor rate is increased at the same time.

Description

technical field [0001] The invention relates to a regulating valve device, more precisely a novel sealing regulating valve device for regulating the vacuum degree of an extruder. Background technique [0002] At present, many different extruder production equipment have different requirements for vacuum degree, and the existing vacuum degree adjustment device is completed by a combination of ball valve and needle valve. First, the staff try their best to make the vacuum degree of the production equipment meet the required vacuum degree by adjusting the ball valve, and then adjust through the needle valve to achieve the required vacuum degree. However, sometimes the vacuum degree has not reached the ideal state after adjusting the needle valve, which means that there is a problem with the adjustment of the ball valve before, and the ball valve needs to be adjusted again to make the vacuum degree reach the ideal state. Repeating this not only wastes time and labor but also vi...

AI Technical Summary

Problems solved by technology

However, sometimes the vacuum degree has not reached the ideal state after adjusting the needle valve, which means that there is a problem with the previous adjustment of the ball valve, and it is necessary to adjust the ball valve to make the vacuum degree reach the ideal state.

Repeating this not only wastes time and labor but also virtually increases the difficulty of vacuum adjustment, so this technical defect has become a technical problem to be solved urgently by those skilled in the art.
