Description
Technical field
The utility model belongs to sealed connecting component field, and in particular to be a kind of anti-creep steel lining fluorine ball valve of anti-negative pressure.
Background technology
Ball valve refers to making opening and closing element with the spheroid with manhole, and spheroid rotates with valve rod, to realize switching motion
Valve.Standard GB/T21465-2008《Valve term》Defined in be:Opening and closing element (spheroid) is driven by valve rod, and around square work ball valve
The valve to be rotated as axis.Using the regulation and control that also can be used for fluid, wherein its V-type ball of sealing V-type ball valve firmly
There is very strong shearing force, especially suitable for fibre-bearing, small solid pellet between core and the metal seat valve of pile-up welding hard alloy
Deng medium.And multi-pass ball valve not only can flexibly control interflow, shunting and the switching of flow direction of medium on pipeline, while also may be used
Close any passage and two other passage is connected.This class valve should be typically horizontally mounted in the duct.Existing steel lining fluorine
Ball valve, typically it is all suitable for anti-malleation (in the national standard scope of application).But do not consider to be vented suddenly in pipeline well, have
During certain negative pressure, that anti-negative pressure is indifferent be present.And do not consider in use, the rise of temperature and pressure yet
The change of power, with the extension of usage time, lining material is had constantly to contract, and the trend that inner walls iron body departs from
Produce Fluorine-lined layer creep, accelerate Fluorine-lined ball valve out-of-service time in operation, cause whole anti-corrosion pipeline can not normal operation, cause
The production of the chemical enterprise used causes huge loss.
Utility model content
In order to solve the above technical problems, the utility model, which provides one kind, can bear national regulation such valve critical field
Anti- malleation ability, and can bear pipeline empty caused by moment negative pressure, and with the change of temperature and pressure, along with
The extension of usage time, baking layer material will not depart from inner walls iron body because of negative pressure, will not also produce the anti-of creep contraction
The anti-creep steel lining fluorine ball valve of negative pressure.
To achieve the above object, the technical solution adopted in the utility model is a kind of anti-anti- creep steel lining fluorine ball valve of negative pressure,
Including valve body and bonnet, bonnet is set on valve body, and its structural feature is that the wall of valve body and bonnet is provided with dovetail groove and spiral shell
The inwall of hole, valve body and bonnet is provided with lining, and lining is connected by vulcanizing in dovetail groove or screw with valve body and bonnet.
As further improvement of the utility model, lining is made of fluoroplastics.
As further improvement of the utility model, dovetail groove and screw are several.
The beneficial effects of the utility model are:It is reasonable in design, it is simple in construction, collect anti-negative pressure and anti-creeping function, can increase
Add the service life of valve, the operating mode of utilization is broader, to save huge resource using unit.
Brief description of the drawings
Fig. 1 is valve body schematic cross-section of the present utility model;
Fig. 2 is bonnet schematic cross-section of the present utility model;
Wherein, 1- valve bodies, 2- bonnets, 3- dovetail grooves, 4- screws, 5- linings.
Embodiment
Explanation is further explained to the utility model below in conjunction with the accompanying drawings, but does not limit protection model of the present utility model
Enclose.
As shown in Figure 1 to Figure 2, the anti-creep steel lining fluorine ball valve of a kind of anti-negative pressure, including valve body 1 and bonnet 2, bonnet 2 are arranged
On valve body 1, the wall of described valve body 1 and bonnet 2 is provided with dovetail groove 3 and screw 4, and the inwall of valve body 1 and bonnet 2 is provided with
Lining 5, lining 5 are connected by vulcanizing in dovetail groove 3 or screw 4 with valve body 1 and bonnet 2;Described lining 5 uses fluoroplastics
It is made;Described dovetail groove 3 and screw 4 is several.The lining 5 of valve body 1 and bonnet 2 all uniformly overlaps with inwall,
Lining 5 vulcanizes in dovetail groove 3 or the screw of tapping 4, after valve assembles, is used in pipeline, either temperature
Be varied from or moment caused by negative pressure and pressure change, can not cause lining 5 and valve body 1 and bonnet 2 to separate, can reach
To anti-negative pressure -0.075MPa pressure, because wadding has certain draftability, as usage time is elongated, even if lining 5 has
Aging phenomenon, but whole material is thrown away in dovetail groove 3 and screw 4, and creep will not also occur, comply fully with the need of pipeline user
Ask, extend the service life of such a ball valve.
It is obvious to a person skilled in the art that the utility model is not limited to the details of above-mentioned one exemplary embodiment, and
And in the case of without departing substantially from spirit or essential attributes of the present utility model, it can realize that this practicality is new in other specific forms
Type.Therefore, no matter from the point of view of which point, embodiment all should be regarded as exemplary, and is nonrestrictive, this practicality is new
The scope of type limits by appended claims rather than described above, it is intended that the equivalency fallen in claim is contained
All changes in justice and scope are included in the utility model, any reference in claim should not be considered as into limitation
Involved claim.
Moreover, it will be appreciated that although the present specification is described in terms of embodiments, not each embodiment is only wrapped
Containing an independent technical scheme, this narrating mode of specification is only that those skilled in the art should for clarity
Using specification as an entirety, the technical solutions in the various embodiments may also be suitably combined, forms those skilled in the art
It is appreciated that other embodiment.
