Abstract
The utility model provides a grey ball valve is unloaded in pneumatics, including valve body (3), disk seat (6), valve gap (2) and spheroid (7), the pneumatic head of support (12) fixedly connected with (14) is passed through to the top of valve body (3), pneumatic head (14) and upper valve rod (8) and lower valve rod (5) key -type connection, cup joint in fixing in lower slide bearing (4) of valve body (3) below lower valve rod (5), cup joint in fixing in last slide bearing (10) of valve body (3) top upper valve rod (8), be provided with between upper valve rod (8) and valve body (3) filler (11), on, the upper and lower both sides fixed connection of lower valve rod and spheroid (7), junction between disk seat (6) and valve gap (2), junction between valve body (3) and bottom (1) and valve gap (2) all is equipped with sealing device. The beneficial effect of the utility model: it is little to open and close the moment of torsion, sealed effectual, opens and close fastly.
Description
Technical field
A kind of device controlling dust-containing airflow, sweat particle-liquid or pressed powder and flow in the duct in pipe technology field involved by the utility model, particularly pneumatic Unloading ball valve.
Background technique
Pneumatic Unloading ball valve and stopcock are the valves belonging to a type together, and its closure member is spheroid, are to do to rotate a kind of valve reaching unlatching, close around valve body center line by spheroid.Pneumatic Unloading ball valve is mainly used to make the flow direction that cut-off velocity is fast, distribute and change medium in pipeline.The resistance provided for medium due to the body cavity of equality complete in pneumatic Unloading ball valve is very little, therefore only needs the operation that turn 90 degrees with cyclone and very little moment of rotation just can close tightly.Pneumatic ball valve switch is light, and volume is little, can make very heavy caliber, and sealing is reliable, and structure is simple, easy to maintenance, and sealing surface and sphere are everlasting closed state, not easily by medium erosion, are widely used in every profession and trade.Operation moment of torsion and sealing reliability weigh two most important indexs of pneumatic Unloading ball valve, but existing pneumatic Unloading ball valve does not enough in these two aspects, for this reason, the solution that scientific research personnel is constantly seeking, as the oil sealing ball valve occurred in recent years, the lubricant oil that namely pressure injection is special between sealing surface, to form one deck oil film, both strengthen sealing, reduce again operation moment of torsion.
Model utility content
For existing pneumatic Unloading ball valve to operation moment of torsion and the deficiency and the reality need that seal the existence of reliability aspect, the utility model provides a kind of pneumatic Unloading ball valve.
To achieve these goals, technical solution adopted in the utility model is:
Pneumatic Unloading ball valve, comprise valve body, the bottom on valve body is connected to by nut, valve gap and the spheroid be arranged in valve body, valve seat is connected with in valve gap, spring is provided with between valve seat and valve gap, the top of valve body is fixedly connected with pneumatic head by support, pneumatic head is connected with upper valve rod and lower valve rod key, lower valve rod is socketed in the properties of journal bearing lubricated that is fixed on below valve body, upper valve rod is socketed in the upper sliding bearing that is fixed on above valve body, the filler of hold-down grid crimping is provided with between upper valve rod and valve body, upper valve rod is fixedly connected with the both sides up and down of spheroid with lower valve rod, joint between valve seat and valve gap, joint between valve body and bottom and valve gap is provided with seal arrangement,
Described lower valve rod and the Placement between upper valve rod with spheroid are that joggle is connected, and the tenon mouth key that lower valve rod and the upper and lower both sides of upper valve rod and spheroid are opened is connected;
Described seal arrangement is the O RunddichtringO of fluorine rubber material;
Described properties of journal bearing lubricated and upper sliding bearing are copper base alloy material.
The beneficial effects of the utility model: upper and lower valve rod is connected with valve body by sliding bearing, and friction factor is little, and open and close torque is little, open and close flexibly; Valve body and valve seat, valve gap, bottom joint are all sealed by the fluorine rubber ring of heat-resisting, anti-oxidant, oil resistant, corrosion-resistant and resistance to atmospheric aging, by the graphite grazing of stable performance, heat-resisting antidetonation between valve body and valve rod, and good sealing effect; Valve transmission is pneumatic, opens and closes speed fast.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
For overcoming the deficiency that existing pneumatic Unloading ball valve exists operation moment of torsion and sealing reliability aspect, meet reality need, design pneumatic Unloading ball valve (as Fig. 1), comprise valve body 3, the bottom 1 on valve body 3 is connected to by nut, valve gap 2 and the spheroid 7 be arranged in valve body 3, valve seat 6 is connected with in valve gap 2, spring 9 is provided with between valve seat 6 and valve gap 2, the top of valve body 3 is fixedly connected with pneumatic 14 by support 12, be connected with upper valve rod 8 and lower valve rod 5 key for pneumatic 14, lower valve rod 5 is socketed in the properties of journal bearing lubricated 4 that is fixed on below valve body 3, upper valve rod 8 is socketed in the upper sliding bearing 10 that is fixed on above valve body 3, the filler 11 that hold-down grid 13 crimps is provided with between upper valve rod 8 and valve body 3, upper valve rod 8 is fixedly connected with the both sides up and down of spheroid 7 with lower valve rod 5, joint between valve seat 6 and valve gap 2, joint between valve body 3 and bottom 1 and valve gap 2 is provided with seal arrangement, described lower valve rod 5 and the Placement between upper valve rod 8 with spheroid 7 are that joggle is connected, and the tenon mouth key that lower valve rod 5 is opened with upper valve rod 8 and spheroid about 7 both sides is connected, described seal arrangement is the O RunddichtringO of fluorine rubber material, described properties of journal bearing lubricated 4 and upper sliding bearing 10 are copper base alloy material.
Working principle of the present utility model: rotated by pneumatic 14 task driven upper valve rods 8 and lower valve rod 5, because spheroid 7 is fixed on centre by upper valve rod 8 and lower valve rod 5, the upper valve rod 8 of rotation and lower valve rod 5 drive spheroid 7 to rotate, and reach the opening and closing of valve.
The beneficial effects of the utility model: upper and lower valve rod is connected with valve body by sliding bearing, and friction factor is little, and open and close torque is little, open and close flexibly; Valve body and valve seat, valve gap, bottom joint are all sealed by the fluorine rubber ring of heat-resisting, anti-oxidant, oil resistant, corrosion-resistant and resistance to atmospheric aging, by the graphite grazing of stable performance, heat-resisting antidetonation between valve body and valve rod, and good sealing effect; Valve transmission is pneumatic, opens and closes speed fast.
Those ordinary skill in the art simply replace and change is all within this patent protection domain.
