Description
Technical field
The utility model is related to a kind of valve mechanism, particularly a kind of novel cutoff valve.
Background technology
Valve is the structure that fluid is turned on and off in a kind of control piper, and traditional valve mechanism is shown in that Fig. 1 is typically wrapped
Valve body is included, bonnet and valve rod are provided with valve body, when valve rod rotates, the sealing block of valve rod bottom will be with the valve in valve body
Seat is done relative motion, and sealing is realized by the extruding between sealing block and valve seat.In traditional valve mechanism, hermetic unit with
It is plane and plane contact between valve seat, when there is positive pressure therebetween, sealing block deformation, to ensure sealing effectiveness.
This traditional valve mechanism, due to the limitation in structure, the problem of having certain in sealing, simultaneously because needing in valve body
Inside sets pipeline, therefore inner space is relatively small, and flow is also relatively small, and inside has more dead angle, easily
Residue is caused to be left.
The content of the invention
The utility model is that design is ingeniously in order to solve the above-mentioned deficiency present in prior art, propose that one kind is simple in construction
Wonderful, rationally distributed, inner dead space is few, residual is small and sealing effectiveness preferably valve body structure.
Technical solution of the present utility model is：A kind of novel cutoff valve, including valve body 1, valve is provided with valve body 1
Lid 2, the internal thread of bonnet 2 is connected with valve rod 3, and the top of valve rod 3 is provided with handwheel 4, and the bottom of valve rod 3 is provided with valve element 5, and it is special
Levy and be：S plates 6 are fixedly installed in described valve body 1 centre of S plates 6 is provided with truncated cone-shaped sealing surface 9, and truncated cone-shaped is close
Upwards, the bottom of described valve element 5 is provided with sealing ring 10, is solid in the bottom of sealing ring 10 for one end that front cover 9 is relatively large in diameter
Surely the circular gasket 11 connected, and sealing ring 10 and the outline of circular gasket 11 match with the truncated cone-shaped sealing surface 9.
The utility model compared with the existing technology, has the following advantages that：
The valve mechanism of this kind of structure type, its is simple in construction, ingenious in design, rationally distributed, and it is directed to traditional valve
Variety of problems in the presence of structure, designs a kind of special valve mechanism, it creatively by hermetic unit and valve seat it
Between contact surface inclined plane is changed to by plane, and the position of hermetic unit is more downward, and the diameter of contact surface is smaller, so can be with
Obtain better seal effect；Pipeline is no longer set inside it simultaneously, the space of valve inner is made full use of, in equal profile rule
In the case of lattice, the flow of this kind of valve is bigger；And its internal dead angle is relatively small, moreover it is possible to effectively prevent residue from leaving.
Its manufacturing process is simple, and cost of manufacture is cheap, it can be said that it possesses a variety of advantages, is particularly suitable in the art
Popularization and application, its market prospects are very wide.
Brief description of the drawings
Fig. 1 is the structural representation of the valve of traditional structure.
Fig. 2 is the structural representation of the utility model embodiment.
Embodiment
Below in conjunction with brief description of the drawings embodiment of the present utility model.As shown in Figure 1 and Figure 2：A kind of new cut-off
Valve body 1 based on valve, including one, is provided with bonnet 2 on valve body 1, and the internal thread of bonnet 2 is connected with valve rod 3, and valve rod
3 top is provided with handwheel 4, and the bottom of valve rod 3 is provided with valve element 5, S templates 6 has been fixedly disposed in valve body 1, at this
The center of individual S templates 6 offers truncated cone-shaped sealing surface 9, and the extreme direction being relatively large in diameter of truncated cone-shaped sealing surface 9 is upward,
Sealing ring 10 is provided with the bottom of the valve element 5, and circular gasket 11 is also fixedly connected with the lower section of sealing ring 10, and
The madial wall of sealing ring 10 and the outline of circular gasket 11 and the truncated cone-shaped sealing surface 9 matches.
The course of work of the novel cutoff valve of the utility model embodiment is as follows：Described S templates 6 are by the inner chamber of valve body 1
It is divided into upper and lower two parts, fluid flows into the top half of the inner chamber of valve body 1 from the left hand inlet port of valve body 1, and by S templates 6
Opening（The inwall of the opening is truncated cone-shaped sealing surface 9）The latter half is flowed into, is flowed out eventually through the outlet on right side；
When needing to close valve, by the rotation valve rod 3 of handwheel 4, driving valve element 5 is descending, the He of sealing ring 10 of the bottom of valve element 5
The outside of circular gasket 11 is squeezed on truncated cone-shaped sealing surface 9, and occurs elastic deformation in the presence of extruding, by S templates 6
Closure of openings, the upper and bottom section of the inner chamber of valve body 1 is isolated, and valve is closed；
Because the contact surface of sealing ring 10, circular gasket 11 and truncated cone-shaped sealing surface 9 is inclined plane, and more downward sealing
The diameter in face is smaller, that is, valve element 5 position more on the lower, the elastic deformation amount of sealing ring 10 and circular gasket 11 is bigger, because
This sealing effectiveness is also better；
Any pipeline need not be set in the valve body 1 of this kind of valve simultaneously, therefore, it is possible to make full use of in the inner chamber of valve body 1
Space, i.e., in the case of equal valve volume, the flow of this kind of valve is bigger；Also due to the inside of valve body 1 need not be set
Dead angle in pipeline or other mechanisms, therefore its inner chamber is relatively fewer, effectively can prevent residue from leaving.
