Abstract
The utility model provides a sluice valve, which is mainly composed of a valve body, a valve cover (1), a valve stem (2), a sluice plate (3), a driving hand wheel (4), etc. The utility model is characterized in that a sealing bellows (5) is arranged between the valve body and the valve stem (2), and the sealing part between the valve stem (2) and the valve cover (1) can be mutually isolated from a medium space between the sealing bellows (5) and the valve body.
Description
The utility model relates to a kind of gate valve.
Existing gate valve mainly is made of valve body, valve gap, valve rod, flashboard, driving handwheel etc., because valve rod need be made regular lifting action, sealing is easy to generate seepage between valve rod and the valve gap.
The purpose of this utility model provides a kind of gate valve that can prevent the outer seepage of valve rod place medium.
To achieve these goals, technical solution of the present utility model is such: gate valve mainly is made of valve body, valve gap, valve rod, flashboard, driving handwheel etc., wherein between valve body and valve rod, be provided with seal bellows, sealing part between valve rod and the valve gap and the dielectric space between seal bellows and the valve body are isolated mutually.
Owing between valve body and valve rod, be provided with seal bellows in the above-mentioned technical solution, the anti-seep measures such as packing seal of gate valve between original valve gap and valve rod, also be provided with the seal bellows that the sealing part that makes between valve rod and the valve gap and the dielectric space between seal bellows and the valve body are isolated mutually, therefore can effectively prevent the outer seepage of valve rod place medium.
Below in conjunction with drawings and Examples the utility model is described in further detail:
Fig. 1 is the utility model embodiment's a configuration diagram.
Wherein: 1, valve gap; 2, valve rod; 3, flashboard; 4, drive handwheel; 5, seal bellows; 6, valve body main body; 7, add long pipe; 8, flange.
As shown in the figure, gate valve mainly is made of valve body, valve gap 1, valve rod 2, flashboard 3, driving handwheel 4 etc., wherein between valve body and valve rod 2, be provided with seal bellows 5, sealing part between valve rod 2 and the valve gap 1 and the dielectric space between seal bellows 5 and the valve body are isolated mutually, valve body by valve body main body 6, add the welding of long pipe 7, flange 8 three parts and constitute, the valve stem passage of valve body is longer, and the gate valve of this structure can prevent the outer seepage of valve rod place medium effectively.
Claims (2)
1, a kind of gate valve, mainly by valve body, valve gap (1), valve rod (2), flashboard (3), driving handwheel formations such as (4), it is characterized in that: between valve body and valve rod (2), be provided with seal bellows (5), sealing part between valve rod (2) and the valve gap (1) and the dielectric space between seal bellows (5) and the valve body are isolated mutually.
2, gate valve according to claim 1 is characterized in that: the valve stem passage of valve body is longer, valve body by valve body main body (6), add the welding of long pipe (7), flange (8) three parts and constitute.
