Description
Technical field
Valve manufacture field is the utility model is related to, more particularly to a kind of ball valve being conveniently replaceable.
Background technology
Ball valve is not only simple in structure, favorable sealing property, and small volume, quality in the range of certain inside nominal diameter
Gently, material consumption is few, easy to operate, and the application of ball valve was more and more wider in recent years, and existing ball valve is when requiring replacement, often whole
Body carries out changing the waste for causing resource, and when pressure medium is too high in ball valve, vibrations caused by controlled valve can influence
The service life of valve.Therefore, how to reduce the waste of resource, reduce the vibrations of spheroid so as to extend the service life of valve,
The problem that always whole society faces.
Utility model content
The purpose of this utility model is to provide a kind of ball valve being conveniently replaceable, to solve above-mentioned technical problem.
The utility model uses following technical scheme to achieve the above object：
A kind of ball valve being conveniently replaceable, including valve body, spheroid, bonnet, connecting rod, the axis of the valve body are provided with spiral shell
The bottom of connection is followed closely, the vertical direction of bottom is provided with spheroid, and in valve body, the center line of the spheroid is provided with sphere installation
The connecting rod of bearing pin connection, the free end of connecting rod are nested with spanner, and the connecting rod runs through bonnet, and bonnet passes through bolt and valve
Body is attached, and the valve body is provided with the valve plate of two screw rod connections, and valve plate is symmetrical arranged along spheroid, along the gravity side of valve plate
Branch pipe is welded with to the bottom of upper valve body, two branch pipes are connected by metal threaded pipe.
Preferably, the branch pipe is provided with bolted gate valve, and the aperture of branch pipe is equal to the aperture of 1/20 valve body.
Preferably, the bottom is detachable, and bottom is surrounded by sealing strip.
Preferably, the aperture of the valve plate is equal to the aperture of valve body, and valve plate is normally open state.
Compared with prior art, the utility model has advantages below：The utility model is simple in construction, reasonable in design；When
When wearing occurs in spheroid or connecting rod is got rusty, bottom can be opened by screw, close valve plate by valve before opening bottom
Isolated at the spheroid of door, bottom can be individually replaced after opening to spheroid or connecting rod, and change speed；When
For valve in pumped (conveying) medium, closing the impulsive force of valve medium suddenly can make valve produce vibrations, influence the service life of valve,
Shutoff valve so reduces in front of the door by branch pipe and metal threaded pipe by the import of valve, outlet and closes valve suddenly and be situated between
The impulsive force of confrontation valve, is preferably promoted the use of.
Brief description of the drawings
Fig. 1 is the ball valve schematic diagram that the utility model is conveniently replaceable.
Fig. 2 is the ball valve sectional view that the utility model is conveniently replaceable.
Fig. 3 is the spheroid schematic diagram for the ball valve that the utility model is conveniently replaceable.
In figure：1st, valve body, 2, branch pipe, 3, metal threaded pipe, 4, screw, 5, gate valve, 6, spheroid, 7, valve plate, 8, bonnet, 9,
Spanner, 10, connecting rod, 11, bottom, 12, bearing pin.
Embodiment
The utility model is further elaborated with specific embodiment below in conjunction with the accompanying drawings.
As Figure 1-3, a kind of ball valve being conveniently replaceable, including valve body 1, spheroid 6, bonnet 8, connecting rod 10, the valve
The axis of body 1 is provided with the bottom 11 that screw 4 connects, and bottom 11 is detachable, and bottom 11 is surrounded by sealing strip, sealing
Bar ensure that the seal between valve body and bottom, and the vertical direction of bottom 11 is provided with spheroid 6, and spheroid 6 is arranged in valve body 1,
The center line of the spheroid 6 is provided with the connecting rod 10 that bearing pin 12 connects, and the free end of connecting rod 10 is nested with spanner 9, described
Connecting rod 10 runs through bonnet 8, and bonnet 8 is attached by bolt and valve body 1, and the valve body 1 is provided with what two screw rods connected
Valve plate 7, the aperture of valve plate is equal to the aperture of valve body, and valve plate is normally open state, and valve plate 7 is symmetrical arranged along spheroid 6, valve plate energy
It is enough to isolate spheroid and connecting rod, so as to be easy to the replacing of spheroid or connecting rod, along the gravity direction upper valve body 1 of valve plate 7
Bottom be welded with branch pipe 2, two branch pipes 2 are connected by metal threaded pipe 3, and branch pipe is provided with bolted gate valve, branch pipe
Aperture be equal to the aperture of 1/20 valve body, the pressure that branch pipe and metal threaded pipe can be between compensation flap inlet and outlets, lower
Impulsive force of the medium to valve.
Utility model works principle：Medium is entered by the import of valve body 1, when needing that valve is turned off or on
When, first the gate valve 5 on two branch pipes 2 is opened, makes import and the outlet of valve, reduces and turns off or on valve suddenly
Medium impulsive force to caused by it, so as to extend the service life of valve, again by branch pipe 2 after the completion of valve opening or closing
On gate valve 5 close；When spheroid 6 or connecting rod 10 are damaged, two valve plates 7 are closed so as to which spheroid 6 be isolated,
Bottom 11 is opened using screw 4, this makes it possible to the waste that avoids resource is individually replaced to spheroid 6 or connecting rod 10.
Described above is the utility model preferred embodiment, for the ordinary skill in the art, according to this reality
With new teaching, in the case where not departing from principle of the present utility model and spirit, the change that is carried out to embodiment, repair
Change, replace and modification is still fallen within the scope of protection of the utility model.
