Description
Technical field
The utility model belongs to forging three-chip type fixing ball valve technical field, more particularly to a kind of that there is modified to seal knot
The forging three-chip type fixing ball valve of structure.
Background technology
Forging three-chip type fixing ball valve is one kind of valve, and structure composition includes spheroid, valve body, sealing shroud, valve rod etc..It is close
Big envelope and valve body are Split type structures, and airtight and watertight padding can be just made after only being bolted sealing shroud and valve body with bolt to valve stem
Position sealing.Current scheme is that sealing shroud and valve body contact position are processed into cylinder.Because bolted through hole compares spiral shell
Bolt basic size is big, so when mounted, sealing shroud will be rotated along valve rod axis direction, because valve needs 90 degree of limitation
The switch of position, valve rod fixing device is provided on sealing shroud again, if sealing shroud is offset after certain angle, valve opening and closing
When, just occurred open or open less than phenomenon, influence valve use.
Utility model content
Regarding to the issue above, applicant passes through Improvement, now provides a kind of close with modified by the utility model
The forging three-chip type fixing ball valve of seal structure, it is therefore intended that make valve assemble accurate positioning, it is reasonable to open and close, and solves valve switch
The problem of not in place or mistake is opened, and sealed reliable.
Embodiment of the present utility model is adopted the following technical scheme that：
A kind of forging three-chip type fixing ball valve with modified sealing structure, including spheroid, bonnet, valve body, sealing shroud,
Valve rod, airtight and watertight padding, bolt and valve rod fixing device；The sphere installation in the space surrounded by valve body and bonnet,
The outside of the valve rod is cased with sealing shroud, and airtight and watertight padding, the valve are placed between the sealing shroud inside top and valve rod
Bar and sealing shroud are connected after passing through the through hole in the middle part of the valve body together with the spheroid；Through hole and institute in the middle part of the valve body
It is consistent square of shape size to state the position of sealing shroud and valve body contact；The valve rod fixing device is set on the valve rod
And with the top contact of the sealing shroud, the bolt sequentially pass through be fixed on after the valve rod fixing device, sealing shroud it is described
On valve body.
According to one side of the present utility model, the contact site of the sealing shroud and valve body is interference fit.
According to one side of the present utility model, the contact site of the sealing shroud and valve body is plane contact.
It is described with having groove on the contact surface of valve rod on the inside of the sealing shroud according to one side of the present utility model
Sealing strip or lubricant are provided with groove.
It is described with having groove on the contact surface of valve body on the outside of the sealing shroud according to one side of the present utility model
Sealing strip or lubricant are provided with groove.
The advantage that the utility model is implemented：
The utility model has carried out Curve guide impeller to the sealing structure for forging three-chip type fixing ball valve, by sealing shroud and valve body
Contact site makes square plane contact into, limits axial movement when sealing shroud is installed, during installation, sealing shroud and valve body contact
Position milling is to flat contact, it is to avoid the axial movement of sealing shroud, realizes that the switch of valve is spacing.Connect on the inside of sealing shroud with valve rod
Sealing strip or lubricant are set in groove, groove with being set respectively on the contact surface of valve body in contacting surface, on the outside of sealing shroud, enhancing sealing effect
Really.Valve assembling accurate positioning after improvement, it is reasonable to open and close, and it is not in place or cross and open this problem to solve valve switch, passes through
Overtesting, valve operation and sealed reliable.
Brief description of the drawings
, below will be to make needed for embodiment in order to illustrate more clearly of the technical scheme in the utility model embodiment
Accompanying drawing is briefly described, it should be apparent that, drawings in the following description are only some embodiments of the present utility model,
For those of ordinary skill in the art, on the premise of not paying creative work, it can also be obtained according to these accompanying drawings
Other accompanying drawings.
Fig. 1 is the front sectional view that the utility model forges three-chip type fixing ball valve.
Fig. 2 is sealing shroud and the top view at valve body contact position in Fig. 1.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is carried out
Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of the utility model, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment obtained, belongs to the scope of the utility model protection.
As shown in figure 1, the utility model is the forging three-chip type fixing ball valve with modified sealing structure, including spheroid
101st, bonnet 102, valve body 103, sealing shroud 104, valve rod 105, airtight and watertight padding 106, bolt 107 and valve rod fixing device 108.
As shown in figure 1, the two ends of valve body 103 are provided with bonnet 102, spheroid 101 is arranged on by valve body 103 and bonnet 102
