Abstract
Provided is a novel plug valve. The novel plug valve mainly solves the problems that an existing plug valve after diameter reduction machining is large in fluid resistance, large in cock torque, low in controlling performance and poor in adjusting effect. The novel plug valve is characterized in that two symmetric square grooves (2) are formed in the side face of a cock column (2), a baffle (5) is formed between the two square grooves (2), the baffle (5) is provided with a first position and a second position, the faces of the square grooves are perpendicular to a flow channel (4) at the first position, and the faces of the square grooves are parallel to the flow channel (4) at the second position. According to the novel plug valve, a cock mechanism is changed, the cock with the square grooves in the two sides is adopted, the flow quantity of the valve is increased, the cock torque is small, opening and closing are flexible, and the controlling performance is good.
Description
Technical field
The utility model relates to a kind of valve, is specifically related to a kind of Novel plug valve.
Background technique
Stopcock is widely used in industry-by-industry, and especially all kinds of heavy industrys, chemical industry make passway on valve plug identical with passway on valve body or separate by 90-degree rotation, realize a kind of valve of opening or closing.Stopcock is best suited for and cuts off and connect medium.Stopcock is many can carry out undergauge processing, so that valve smaller volume, weight lightens, and price reduces, but the valve of establishing through undergauge, fluid resistance can become greatly, causes valve torque to increase, and controlled reduction, makes regulating effect variation.Can make sealing surface friction increase, reduce working life simultaneously.
Model utility content
In order to overcome the deficiency of background technique, the utility model provides a kind of Novel plug valve, mainly solves traditional mechanism sealing poor, the problem of poor reliability.
The technological scheme that the utility model adopts is: a kind of Novel plug valve, comprise valve body, cock post, in described valve body, be provided with runner, described cock post side is provided with two symmetrical square grooves, between two described square grooves, be formed with baffle plate, described baffle plate has the primary importance second place parallel with runner with square groove face that square groove face is vertical with runner.
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, between described valve gap and valve body, be provided with successively pressing plate, PTFE sealing gasket, O shape circle, described cock styletable face is provided with O shape and encloses adaptive standing groove, described PTFE sealing gasket and the laminating of 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 beneficial effects of the utility model are: changed the mechanism of cock, adopted the cock of both sides band square groove, increased the discharge value of valve, cock moment of torsion is little, open and close flexibly, controlled good.
Accompanying drawing explanation
Fig. 1 is explosive view of the present utility model.
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 circle, 10-spin-block, 101-square face.
Embodiment
Below in conjunction with accompanying drawing, the utility model embodiment is described further:
As shown in Figure 1 with Figure 2, a kind of Novel plug valve, comprise valve body 1, cock post 2, in described valve body 1, be provided with runner 4, described cock post 2 sides are provided with two symmetrical square grooves 21, between two described square grooves 21, be formed with baffle plate 5, described baffle plate 5 has the primary importance second place parallel with runner 4 with square groove face that square groove face is vertical with runner 4.
Described cock post 2 ends are 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 adaptations.
Described valve body 1 is provided with valve gap 6, between described valve gap 6 and valve body 1, be provided with successively pressing plate 7, PTFE sealing gasket 8, O shape circle 9, described cock post 2 end faces are provided with the standing groove 22 that encloses 9 adaptations with O shape, described PTFE sealing gasket 8 and the 2 end face laminatings of cock post, 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 concrete use of the utility model is as follows: when work, cock post 2 rotates, make square groove face parallel with runner 4 directions, owing to only having stopping 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, and cock post 2 lifting surface areas are little, opens and closes flexibly.
The beneficial effect of model utility is: changed the mechanism of cock, adopted the cock of both sides band square groove, increased the discharge value of valve, cock moment of torsion is little, opens and closes flexibly, controlled good.
