Description
Technical field
The utility model relates to a kind of stopcock, particularly relates to a kind of cock with fluoride lining with good seal performance.
Background technique
In pipeline construction, stopcock is a kind of valve be well used, and makes the passway in cock identical with the passway on valve body or separate, realize unlatching or the closedown of valve by 90-degree rotation.The cock shape of stopcock is generally cylindrical or conical, and in cylindrical plug, passage is generally orthogonal, and passage is in echelon in conical cock.These shapes make the structure of stopcock become very light and handy.Stopcock is most suitable as cut-out and connect medium and shunting use.
Stopcock is in the market made up of valve body, cock, valve gap, filler and gland substantially.The interior sealing pair of valve directly contacts sealing by accurately machined metallic plug body with valve body, and such valve opening and closing moment is large, not easily opens and closes and easily weares and teares; The external sealed of valve has two positions, is respectively the sealing between valve body and valve gap and the sealing between valve rod and valve gap, and the sealing of this two place relies on compression valve gap and gland extruding filler and then compression valve rod to complete respectively.The stopcock sealing imperfection of this spline structure, easily reveals and causes valve function to lose.
Model utility content
For the problems referred to above, the utility model object is to provide that a kind of to open and close moment little, the corrosion-resistant and cock with fluoride lining of favorable sealing property.
To achieve these goals, the technical solution of the utility model is as follows:
A kind of cock with fluoride lining, comprise valve body, the cock be arranged in valve body, the valve rod that is fixedly connected with described cock, the conical surface of described cock and valve interior wall adaptation, described valve rod place is provided with valve gap, sealing gasket is provided with between valve body above described cock and valve gap, the gland that longitudinal section is L-type is provided with above sealing pad, this gland is sleeved on described valve rod, valve rod above described gland is provided with gland, when tightening this gland, described gland will extrude described sealing gasket and valve rod simultaneously.
Adopt the stopcock of the utility model structure, owing to having set up sealing gasket and added gland between valve body and valve gap above sealing pad, during extruding gland, gland is downward press seal pad axially, lateral extrusion valve body makes valve rod and valve body compress, and makes valve seal safer.
The preferred fluoroplastic of material of described sealing gasket, fluoroplastic have excellent corrosion resistance, can resist the corrosion of flowing medium.
One of the present utility model is preferred, valve body below described gland is provided with annular groove, this annular groove and described valve rod coaxial line, its diameter is less than the maximum extension diameter of described gland, this annular groove is placed with O RunddichtringO, and the longitudinal section diameter of described O RunddichtringO is greater than the degree of depth of described annular groove.
Add the stopcock of O RunddichtringO, seal more perfect.
Equally, the preferred fluoroplastic of the material of O RunddichtringO.
Another kind of the present utility model is preferred, and the conical surface of described cock and valve seal is provided with columnar projections along cock axial direction, and described columnar projections contacts with valve interior wall.
Adopt the stopcock of this spline structure, sealing between the cock conical surface and valve body relies on columnar projections and valve interior wall contact segment to complete, and sealing contact surface reduces greatly, and during valve opening and closing, surface friction drag also diminishes thereupon, reduce the keying moment of valve, valve is is more easily opened and closed.
Another kind of the present utility model is preferred, and the inwall of described valve body, the outer surface of cock are provided with fluoroplastics lining with the part surface that flowing medium directly contacts, and ensures that valve body mechanism can not be corroded by flowing medium, extends the working life of valve.

Embodiment
Being easy to make technological means of the present utility model and implementation understand, setting forth the utility model further below in conjunction with specific embodiment.
See Fig. 1, the utility model cock with fluoride lining comprises valve body 1, the cock 2 be arranged in valve body 1, the conical surface of this cock 2 and the inwall adaptation of valve body 1, and valve rod 8 is fixedly connected with cock 2, and drive cock 2 is rotated by rotary valve rod 8, completes the keying of valve; At valve rod 8, place is provided with valve gap 5, and be provided with sealing gasket 4 between valve body 1 above cock 2 and valve gap 5, gland 6 is provided with above sealing gasket 4, the loop configuration of this gland 6 to be longitudinal sections be L, its internal diameter and valve rod 8 diameter adaptation, be sleeved on valve rod 8, valve rod 8 above gland 6 is provided with gland 7, when tightening gland 7, gland 7 extrudes gland 6, make gland 6 axially downward press seal pad 4, lateral extrusion valve body 1 makes valve body 1 and valve rod 8 compress, and guarantees the sealing of valve entirety.The preferred fluoroplastic of material of sealing pad 4, because fluoroplastic have excellent corrosion resistance, almost can resist the corrosion of all chemical mediators and flowing medium.
In the utility model, also the valve body 1 below gland 6 can process an annular groove 9, this annular groove 9 and valve rod 8 coaxial line, its diameter is less than the maximum extension diameter of gland 6, guarantee that the lower end surface of gland 6 covers on this annular groove 9, O RunddichtringO 3 is placed in annular groove 9, the longitudinal section diameter of this O RunddichtringO 3 is slightly larger than the degree of depth of annular groove 9, O RunddichtringO 3 is made to exceed annular groove 9, like this when compressing gland 6, the lower end surface of gland 6 will compress O RunddichtringO 3, make the radial seal of valve more perfect.
See Fig. 2, in the utility model, columnar projections structure 11 can be provided with on the conical surface of cock 2, this columnar projections structure 11 is arranged along the axial direction of cock 2, described columnar projections 11 and valve body 1 contact internal walls, the stopcock of this spline structure, sealing between cock 2 conical surface and valve body 1 relies on columnar projections 11 and valve body 1 contact internal walls part to complete, sealing contact surface reduces greatly, seal pressure increases, improve sealability, and due to sealing contact surface reduction, surface friction drag during valve opening and closing also diminishes thereupon, reduce the keying moment of valve, make valve opening and closing more smooth and easy.
