Abstract
The utility model discloses an inflatable no-wear ball valve comprising an upper valve body, a lower valve body, a valve seat, a ball body, an upper valve shaft, a lower valve shaft, an O-shaped sealing ring, a spring, an air cavity, a bearing, a driving device and the like. The drive mode can be a plurality of forms such as manual operation, air-actuated operation, motor-driven operation and the like. The inflatable no-wear ball valve can effectively solve the problems that a sealing pair is abraded and damaged caused by the long-term friction of the sealing pair in the traditional ball valve in the industries such as metallurgy and the like. When the inflatable no-wear ball valve is sealed, an external air source opens automatically, and charges the air cavity, the air pressure pushes the valve seat to move axially towards the ball body, so as to do sealing movement, and a sealing surface is combined with the ball body instantly without frictional wear; and when the inflatable no-wear ball valve, the external air source closes automatically, the air cavity releases pressure, the valve seat moves along the direction opposite to the ball body by depending on the restoring force of the spring, the valve seat is disconnected with the ball body instantly without frictional wear, and the upper valve shaft drives the ball body to rotate, and the ball vale is opened.
Description
Described technical field
The utility model relates to a kind of gas-filled type does not have the wearing and tearing ball valve, can be used for cutting off media such as coal dust, coal gas, air, can be widely used in industries such as metallurgy.
Background technique
In industries such as metallurgy, dry method dust unloads system pipelines such as ash, coal powder injection all to be needed to carry, control the circulation of media such as coal ash, gas or block, employed ball valve in the present metallurgy industry, in the process of opening, closing, sealing surface and spheroid are in Frotteurism always, sealing surface very easily weares and teares, thereby causes the leakage of media such as coal dust, coal gas and the damage of equipment.The utility model gas-filled type does not have the process of wearing and tearing ball valve in opening and closing, and sealing surface and spheroid are in disengaged position always, do not have any wearing and tearing, have greatly improved the working life and the reliability of product.
The model utility content
The purpose of this utility model provides a kind of gas-filled type does not have the wearing and tearing ball valve, and this valve sealing surface in the opening and closing process does not have wearing and tearing, friction, the working life that can greatly improve product.
The technical solution adopted in the utility model is:
The utility model discloses a kind of gas-filled type and do not have the wearing and tearing ball valve, comprise upper valve body, following valve body, valve seat, spheroid, go up valve shaft, lower valve shaft, O RunddichtringO, spring, air cavity, bearing, drive unit etc., driving mode can be manual, pneumatic, hydraulic pressure, various ways such as electronic.When gas-filled type does not have the unlatching of wearing and tearing ball valve, sealing surface of seat and spheroid are in the applying sealing state, the external source of the gas of air cavity is closed earlier pressure release automatically, because the disappearance of air pressure, spring in the spring seat will produce the end thrust that deviates from spheroid to valve seat, thereby make sealing surface of seat and spheroid disengaging sealing, and then drive unit drives and goes up the valve shaft rotation, last valve shaft drives spheroid and turns to spheroid through hole fully open position, and the valve opening action is finished.Do not have the wearing and tearing ball valve at gas-filled type and close in the whole process of standard-sized sheet, because valve seat and spheroid disengaging, so sealing surface does not have any friction, wearing and tearing.Gas-filled type does not have the wearing and tearing ball valve when closing, valve base sealing seat, spheroid are in disengaged position, drive unit drives goes up the valve shaft rotation, last valve shaft drives spheroid and turns to spheroid through hole complete shut-down position, the air cavity external gas is derived to move air cavity is inflated then, air-flow promotion valve base sealing seat is drawn close, fits, is sealed to spheroid in the air cavity, and the valve closing action is finished.Do not have the wearing and tearing ball valve at gas-filled type and be opened in the closed procedure of pass, valve seat and spheroid are in mutual disengaged position when driving the spheroid rotation owing to last valve shaft, exist so there is any friction and wear, have prolonged the working life of sealing surface effectively.
Description of drawings
Fig. 1 is a structural representation of the present utility model, wherein
1, upper valve body flange 2, upper valve body 3, air cavity 4, valve seat 5, O RunddichtringO 6, pressure spring 7, hexagon socket head cap screw 8, spring seat 9, last valve shaft 10, upper end cap 11, hexagon socket head cap screw 12, O RunddichtringO 13, bearing 14, key 15, spheroid 16, following valve flange 17, following valve body 18, key 19, lower valve shaft 20, bearing 21, lower end cap 22, hex head bolt 23, connecting bolt 24, sealing surface of seat
Embodiment:
As shown in Figure 1, the utility model gas-filled type does not have the wearing and tearing ball valve, comprise upper valve body 2, following valve body 17, valve seat 4, spheroid 15, upper valve body flange 1, following valve flange 16, upper valve body flange 1 and following valve flange 16 are connected and fixed by connecting bolt and pipeline, upper valve body 2 and following valve body 17 are connected and fixed by connecting bolt 23, external drive unit is connected with last valve shaft 9 and drives valve shaft 9 does complete cycle rotation (valve shaft 9 outer rings are with bearing 13), last valve shaft 9 outsides are with upper end cap 10, upper end cap 10 is fixedly connected on down on the valve body 17 by interior hexagonal 11, key 14 is equipped with in last valve shaft 9 ends, key 14 is connected and fixed with spheroid, and valve shaft 9 drives spheroid by key 14 and does the complete cycle rotation.During valve closing, valve shaft 9 drives spheroids 15 and turns to the spheroid closed position, and the external air source of air cavity 3 begins inflation and promote valve seat 4 to shift to spheroid 15 and seal; During valve opening, the external air source of air cavity 3 stops inflation, air cavity 3 beginning pressure releases, thereby the pressure spring 6 in the spring seat 8 (spring seat 8 is fixed in the upper valve body 2 by hexagon socket head cap screw 7) begins to reply, and promotion valve seat 4 moves to the opposite direction of spheroid 15, thereby sealing surface of seat 24 and spheroid break away from, and then go up valve shaft 9 drive spheroids 9 and turn to fully open position, and gas-filled type does not have wearing and tearing ball valve opening process to be finished.Spheroid 15 the other ends are connected 19 supporting sepheres 15 of lower valve shaft, assistant sphere 15 rotary actions by key 18 with lower valve shaft 19.Lower valve shaft 19 outer rings are with bearing 20, and lower end cap 21 is fixedlyed connected with following valve body 19 by hex head bolt 22.O RunddichtringOs such as O RunddichtringO 5,12 seal.
