Abstract
The utility model relates to an anticorrosive ball valve which comprises a valve body, a valve rod and a ball core, wherein the valve body is provided with an inlet and an outlet; a fluid flow passage is arranged between the inlet and the outlet; the ball core is arranged in the fluid flow passage; and the ball core is provided with a through hole. The anticorrosive ball valve is characterized in that the valve body at the bottom of the ball core is provided with a pressure relief opening; inner walls of the inlet and the outlet both have conical structures; and small-caliber ends of the inlet and the outlet with the conical inner walls are arranged towards the ball core. The anticorrosive ball valve has the advantages of being simple in structure, convenient to operate and long in service life.
Description
Technical field
The utility model relates to a kind of ball valve, is specifically related to a kind of Corrosion-resistant Ball Valve.
Background technique
Existing ball valve in use can cause a part of medium to be closed in the ball valve body body cavity, be in the gap between ball core outer surface and valve body, thereby cause that residual medium corrodes the local failure of ball wicking surface in the ball valve body cavity, body cavity inner sealing medium causes damage because of the extraneous factor superpressure expands to the ball core, influence ball valve working life, to such an extent as to cause the rotten corrosion of residual medium self in the ball valve body cavity, influence the quality of medium; Because existing ball valve entrance and exit is cylindrical shape mostly, not strong to the guided bone of medium circulation, medium is bigger to the impact of ball core again, causes the ball core to damage easily, influences the working life of ball valve.
The model utility content
The purpose of this utility model provides a kind of simple in structure, Corrosion-resistant Ball Valve of being difficult for the burn into long service life.
The technical solution adopted in the utility model is: a kind of Corrosion-resistant Ball Valve, comprise valve body, valve rod and ball core, described valve body is provided with entrance and exit, be provided with the fluid passage between the entrance and exit, described ball core is arranged in the fluid passage, has through hole on the described ball core, and the valve body of described ball core bottom is provided with the row pressure mouth, the inwall of described entrance and exit all is conical structure, and described inwall is the small-caliber end of conical entrance and exit all towards the setting of ball core.
The utility model is provided with the row pressure mouth on the valve body of ball core bottom, residual medium in the gap between ball core and valve body can be discharged by this row pressure mouth, and is easy to operate, only needs regularly or irregularly to open the row pressure mouth and gets final product; In order to reduce the impact force of medium to the ball core, the inwall of entrance and exit all is designed to conical structure, and the small-caliber end of entrance and exit all is provided with towards the ball core, medium just enters from the big opening end of inlet like this, draw in through the osculum end, enter into the through hole of ball core again, bring out at osculum then through outlet, big opening end in outlet diffuses away, this one holds together a structural design of putting, reduced the impact of medium effectively, reduced the rate of corrosion of ball wicking surface, increased the working life of ball core the ball wicking surface.
For the ease of the discharging of residual medium, on the row pressure mouth, can connect waste pipe, this waste pipe is provided with switch gear.
The utility model has the advantages that: simple in structure, easy to operate, long service life.
Description of drawings
Fig. 1 is an overall structure schematic representation of the present utility model.
Wherein: 1, valve body, 2, valve rod, 3, the ball core, 4, inlet, 5, outlet, 6, the fluid passage, 7, through hole, 8, the row pressure mouth, 9, waste pipe, 10, switch gear, 11, the spheroid body cavity.
Embodiment
As shown in Figure 1, a kind of Corrosion-resistant Ball Valve, comprise valve body 1, valve rod 2 and ball core 3, on valve body 1, be provided with inlet 4 and outlet 5, the inlet 4 and export 5 between be provided with fluid passage 6, ball core 3 just is arranged in the fluid passage 6, on ball core 3, have through hole 7, in order to get rid of residual medium in the spheroid body cavity 11 easily, on the valve body 1 of ball core 3 bottoms, be provided with row pressure mouth 8,, inlet 4 and the inwall that exports 5 all be designed to conical structure in order to reduce the impact force of medium to ball core 3, and enter the mouth 4 and outlet 5 small-caliber end all be provided with towards ball core 3, medium just enters from 4 the big opening end of entering the mouth like this, draws in through the osculum end, enters into the through hole 7 of ball core again, bring out at osculum then through outlet 5, big opening end in outlet diffuses away, and this one holds together a structural design of putting, and has reduced the impact of medium to ball core 3 surfaces effectively, reduce the rate of corrosion on ball core 3 surfaces, increased the working life of ball core 3;
For the ease of the discharging of residual medium, on row pressure mouth 8, connect waste pipe 9, this waste pipe 9 is provided with switch gear 10.
Claims (2)
