Description
Technical field
The present invention relates to valve technology field, more particularly, to a kind of ball valve assembly.
Background technology
Ball valve (ball valve) come out in the 1950s, with science and technology rapid development, production technology and
Product structure is continuously improved, and in the 40 short years, has been rapidly developed as a kind of main valve class.In western industrial
Flourishing country, the use of ball valve is continuous year by year to be risen.
In China, ball valve be widely used petroleum refining, long-distance transport pipes, chemical industry, papermaking, pharmacy, water conservancy, electric power,
The industries such as municipal administration, steel occupy very important status in national economy.
Ball valve has following features：Wear-resisting, good seal performance, switch is light, service life is long.
In order to realize the connection of relatively long distance, some ball valves are furnished with extension rod, can not between extension rod and the valve rod of ball valve
The connection of rotation.However, it is easy to situation about leaking occur between the extensional shell of extension rod and extension rod for assembling, certain
In important use environment, immeasurable loss can be caused even dangerous.
Invention content
In view of the deficiency of the prior art, the object of the present invention is to provide a kind of ball valve assemblies, it has sealing
Property is preferable, and the characteristics of be easily assembled.Further, it also has the characteristics that using safer.
To achieve these goals, the technical solution adopted in the present invention is：
Ball valve assembly is fixed on the extensional shell above the valve body including valve body and by flange, wherein, which has
Spherical cavity, the left side of the spherical cavity with water inlet, right side with water outlet, upside with matching hole, and set in the spherical cavity
Have rotatable sphere, which is equipped with water flowing hole, and the sphere is connected with valve rod, the valve rod upwardly extend after from the cooperation
It is pierced by hole, which has transparent mating cavity, and rotatable extension rod, the extension rod are equipped in the mating cavity
Upper end extend out to the outside of the extensional shell upwards, lower end connects the upper end of the valve rod, supporting table is equipped in the matching hole
Rank, the interior filler group being filled with above the support level and the valve rod matches of the matching hole, meanwhile, the extension rod and the valve
Bar socket connection, the interior avris positioned at the mating cavity of the extensional shell are equipped with receiving of the opening to the extensional shell lower surface
Chamber, accommodating chamber is interior to be equipped with hold-down grid, and the lower face of the hold-down grid is pressed in the top of the filler group, and is equipped in the accommodating chamber
The double threaded screw being screwed onto on the valve body, the double threaded screw pass through the upper end of the hold-down grid and the double threaded screw to be bolted with pressure
Tight nut and, the top of the mating cavity is equipped with flaring around the extension rod, and packing padding is equipped in the flaring.
The side wall of the extensional shell is equipped with pressure gauge.

Specific embodiment
Embodiment, as shown in Fig. 1 to Fig. 3：Ball valve assembly is fixed on including valve body 10 and by flange 40 on the valve body 10
The extensional shell 50 of side.Certainly, which is necessarily furnished with seal washer.The valve body 10 has spherical cavity 11, the spherical cavity 11
Left side with water inlet, right side with water outlet 12, upside with matching hole 13.Rotatable ball is equipped in the spherical cavity 11
Body 20, the sphere 20 are equipped with water flowing hole 21.That is, the sphere 20, which is rotated to the water flowing hole 21, connects the water inlet and the water outlet
When 12, which can open.The sphere 20 is connected with valve rod 30, which wears after upwardly extending out of this matching hole 13
Go out.The extensional shell 50 has transparent mating cavity 51, and rotatable extension rod 56, the extension are equipped in the mating cavity 51
The upper end of bar 56 extend out to the outside of the extensional shell 50 upwards, lower end connects the upper end of the valve rod 30.That is, the extension rod 56 prolongs
The length of the valve rod 30 is grown.
It further says, support level 131 is equipped in the matching hole 13, is located at the support level 131 in the matching hole 13
The filler group 132 that top is filled with and the valve rod 30 matches.That is, the filler group 132 seals the circumference of the valve rod 30.
Meanwhile the extension rod 56 and 30 socket connection of valve rod.For example, the lower end of the extension rod 56 is equipped with inserting for quadrangular section
Mouthful, the upper end of the valve rod 30 be equipped with the plug that section is similarly quadrangle, which is inserted in the socket, makes 56 He of extension rod
The valve rod 30 realize connection and it is relatively non-rotatable therebetween.Avris in the extensional shell 50 positioned at the mating cavity 51 is equipped with
It is open to the accommodating chamber 52 of 50 lower surface of extensional shell.Hold-down grid 133 is equipped in accommodating chamber 52, the hold-down grid 133
Lower face is pressed in the top of the filler group 132.Certainly, which is preferably sleeved on the valve rod 30.It is set in the accommodating chamber 52
There is the double threaded screw 531 being screwed onto on the valve body 10, which passes through the hold-down grid 133 and the double threaded screw 531
Upper end be bolted with clamp nut 532.That is, after tightening the clamp nut 532, by the hold-down grid 133 by the filler group
132 compactings.And the top of the mating cavity 51 is equipped with flaring 54 around the extension rod 56, and packing padding is equipped in the flaring 54
55.In this way, the leakproofness of entire ball valve assembly is made to have obtained significant increase, and assembly difficulty is smaller.
Optimization：
The side wall of the extensional shell 50 is equipped with pressure gauge 60.Once it is leaked that is, having in the extensional shell 50, then the pressure
Shown by power table 60 necessarily has, user can learn rapidly.
The side wall of the extensional shell 50 is equipped with angular needle valve 70.It, can be with that is, when there is in the extensional shell 50 leakage
The manually opened angular needle valve 70 carries out pressure release.
Continue to optimize：
On double threaded screw 531 disc spring 533 is equipped with positioned at the lower section of the top of hold-down grid 133, clamp nut 532.In this way,
Meet assembling needs, press excessively tight to avoid filler group 132, influence the normal use of the ball valve.
531 middle part of double threaded screw is equipped with easily broken notch 5311.Meanwhile the side wall of the extensional shell 50 is equipped with pressure valve
80.In this way, avoiding the loss of other component in special circumstances, also avoid leakage and other devices are entered by extension rod 56
In, the safety and reliability when significant increase ball valve assembly uses.
The foregoing is merely the preferred embodiment of the present invention, are not intended to limit the scope of the invention, every utilization
The equivalent structure or equivalent flow shift that description of the invention and accompanying drawing content are made directly or indirectly is used in other correlations
Technical field, be included within the scope of the present invention.
