Abstract
The invention discloses a cylindrical valve. Above the upper cover of a valve body, a manual wrench is arranged above an upper shaft and is connected with an upper frame and a permanent magnet, the upper shaft enters an upper cavity through the upper cover of the valve body and a sealing plate insulates the permanent magnet in the upper cavity from a permanent magnet in a lower cavity, forms certain clearances with the two permanent magnets rather than contacts with the two permanent magnets, and generates a torque rotation under the action of the magnetic forces of the up and down two permanent magnets to open and close the valve; in the lower cavity, the permanent magnet, the lower frame and a rotating shaft cylinder are connected, shafts arranged at two ends of the rotating shaft cylinder are provided with bearings to provide a minimum torque for opening and closing the valve, the rotating shaft cylinder is arranged first in a circular sleeve and an upper plate of the circular sleeve and then in the valve body, and the sealing of the sealing plate and a plurality of times of sealing performed by the circular sleeve, the upper plate of the circular sleeve and the sealing cover prevent a medium from leaking and fulfill the aim of sealing; and the leakage problem of the valve is solved radically.
Description
Affiliated technical field
The present invention relates to a kind of cylindrical valve, start handle especially for a long time, produce friction and cause axle the cylindrical valve that the gap also can not be leaked to occur.
Background technique
At present, each section medium in connection of adopting usually on the market and the cut-out pipeline, the various valves of flow and pressure in the adjusting pipeline, as: gate valve, stop valve, butterfly valve, ball valve, stopcock, modulating valve, throttle valve, reduction valve etc.It is manual, pneumatic and electronic adopting the method for opening and closing, the axle that they drive all communicates with pipeline internal medium, long-time opening and closing cause axle and seal ring friction-produced gap, medium in the pipeline can spill from the gap, if the medium in the pipeline is a combustible substance, as: rock gas, coal gas, oil product, chemical substance runs into naked light, can cause terrible consequences, bring tremendous loss, seepage is the insurmountable for a long time big problems of various valves.
Summary of the invention
In order to solve the leakage problems for a long time of various valves, the invention provides a kind of cylindrical valve, this valve divides two shape chambeies up and down, seals with sealing material.Adopt the two seals method in the pipeline again, do not allow the medium seepage, medium in the pipeline can only move in the shape chamber down, and manually the axle of rotation can only feed the shape chamber, does not contact with medium in the pipeline, manually the axle of rotation connects a permanent magnets, middle across sealing plate, relative in the permanent magnets in shape chamber down, by the magnetic force of permanent magnets, reach the purpose of opening and closing valve, realize the transportation process of pipeline internal medium.
The technical solution adopted for the present invention to solve the technical problems: on valve upper cover, manual wrench is placed on the axle top and puts on the shelf, permanent magnets is connected, and last axle enters the shape chamber by valve upper cover.Across sealing plate, two permanent magnets keep certain clearance with sealing plate up and down, do not contact mutually in the middle of the permanent magnets in the permanent magnets in last shape chamber and following shape chamber, are to produce torsion rotation, the purpose that reaches valve opening and close by the magnetic force of two permanent magnets up and down.Under valve body in the shape chamber, permanent magnets, undercarriage and rotating shaft cylinder are connected, on the axle at rotating shaft cylinder two ends bearing is installed, with other watt axle biggest advantage being installed is to reduce friction and wear and tear, provide minimum torque force to opening and closing, the rotating shaft cylinder is installed in circle cover and the circle cover upper plate, is installed in the valve body again, sealing, the circle of pulling by sealing overlaps, round repeatedly sealing of overlapping upper plate and sealing cover does not allow the medium seepage, reaches the purpose of sealing; Thoroughly solved the leakage problems of valve.
The invention has the beneficial effects as follows, axle on the manual wrench can only enter the last shape chamber of valve body, do not contact with medium in the pipeline, the magnetic force work that produces by two discontiguous permanent magnets in two shape chambeies up and down, realized the purpose that valve is non-leakage, though the manual wrench open and close how long with how long use, can seepage yet, processing ease, simple in structure, easy to process.
