Abstract
A kind of stopcock.Mainly solve the existing stopcock fluid resistance through undergauge processing large, cock moment of torsion is large, and controlling is low, the problem of regulating effect difference.It is characterized in that: described cock post (2) side is provided with two symmetrical square grooves (21), baffle plate (5) is formed with, the second place that described baffle plate (5) has primary importance that square groove face and runner (4) are vertical parallel with runner (4) with square groove face between two described square grooves (21).This mechanism changes the mechanism of cock, and adopt the cock of both sides band square groove, add the discharge value of valve, cock moment of torsion is little, and open and close flexibly, controlling is good.
Description
Technical field
The present invention relates to a kind of valve, be specifically related to a kind of stopcock.
Background technique
Stopcock is widely used in industry-by-industry, especially all kinds of heavy industry, chemical industry, makes the passway on valve plug identical with the passway on valve body or separate by 90-degree rotation, realizes a kind of valve opened or close.Stopcock is best suited for and cuts off and connect medium.Undergauge processing is carried out in the many meetings of stopcock, and to make valve smaller volume, weight, price reduces, but is through the valve that undergauge establishes, and fluid resistance can become large, causes valve torque to increase, and controlling reduction, makes regulating effect be deteriorated.Sealing surface can be made to rub increase, working life reduces simultaneously.
Summary of the invention
In order to overcome the deficiency of background technique, the invention provides a kind of stopcock, mainly solving traditional mechanism sealing poor, the problem of poor reliability.
The technical solution adopted in the present invention is: a kind of stopcock, comprise valve body, cock post, runner is provided with in described valve body, described cock post side is provided with two symmetrical square grooves, baffle plate is formed with, the second place that described baffle plate has primary importance that square groove face and runner are vertical parallel with runner with square groove face between two described square grooves.
Described cock column end is integrally formed with spin-block, and described spin-block is provided with square face, and described handle is provided with the through hole with spin-block adaptation.
Described valve body is provided with valve gap, be provided with pressing plate between described valve gap and valve body successively, PTFE sealing gasket, O shape enclose, described cock styletable face is provided with encloses adaptive standing groove with O shape, fit in described PTFE sealing gasket and cock styletable face, described pressing plate and PTFE sealing gasket interference fit.
Described valve gap is connected with valve body by some screws.
Described runner comprises feed liquor runner, fluid runner, and described feed liquor runner, fluid runner are V-shaped.
Described valve body is provided with handle, and described cock post and handle are linked.
The invention has the beneficial effects as follows: the mechanism changing cock, adopt the cock of both sides band square groove, add the discharge value of valve, cock moment of torsion is little, and open and close flexibly, controlling is good.
Accompanying drawing explanation
Fig. 1 is explosive view of the present invention.
Fig. 2 is the sectional view of valve body 1.
1-valve body in figure, 2-cock post, 21-square groove, 22-standing groove, 3-handle, 31-through hole, 4-runner, 41-feed liquor runner, 42-fluid runner, 5-baffle plate, 6-valve gap, 7-pressing plate, 8-PTFE sealing gasket, 9-O shape is enclosed, 10-spin-block, 101-square face.
Embodiment
Below in conjunction with accompanying drawing, embodiments of the present invention is further illustrated:
As shown in Figure 1 with Figure 2, a kind of stopcock, comprise valve body 1, cock post 2, runner 4 is provided with in described valve body 1, described cock post 2 side is provided with two symmetrical square grooves 21, baffle plate 5 is formed with, the second place that described baffle plate 5 has primary importance that square groove face and runner 4 are vertical parallel with runner 4 with square groove face between two described square grooves 21.
Described cock post 2 end is integrally formed with spin-block 10, and described spin-block 10 is provided with square face 101, and described handle 3 is provided with the through hole 31 with spin-block 10 adaptation.
Described valve body 1 is provided with valve gap 6, be provided with pressing plate 7 between described valve gap 6 and valve body 1 successively, PTFE sealing gasket 8, O shape enclose 9, described cock post 2 end face is provided with the standing groove 22 enclosing 9 adaptations with O shape, described PTFE sealing gasket 8 is fitted with cock post 2 end face, described pressing plate 7 and PTFE sealing gasket 8 interference fit.
Described valve gap 6 is connected with valve body 1 by some screws.
Described runner 4 comprises feed liquor runner 41, fluid runner 42, and described feed liquor runner 41, fluid runner 42 are V-shaped.
Described valve body 1 is provided with handle 3, and described cock post 2 is linked with handle 3.
The present invention specifically uses as follows: during work, and cock post 2 rotates, and makes square groove face parallel with runner 4 direction, owing to only there is the stop of one deck baffle plate 5 between feed liquor runner 41, fluid runner 42, compared to original perforate plug valve, discharge value is very big, cock post 2 lifting surface area is little, opens and closes flexibly.
The beneficial effect of the invention is: the mechanism changing cock, and adopt the cock of both sides band square groove, add the discharge value of valve, cock moment of torsion is little, and open and close flexibly, controlling is good.
