Abstract
The utility model relates to a filter type floating ball valve. The filter type floating ball valve comprises a valve body, a valve rod, a valve ball, a valve seat supporting ring and a pressing ring, wherein a transverse medium channel is formed in the valve body, the valve rod is longitudinally and coaxially installed in the middle of the valve body, the valve ball is coaxially installed at the lower end of the valve rod in the valve body in a driving mode and is provided with a T-shaped channel, a filter screen is fixedly installed at the outlet end of the valve ball through multiple screws which are evenly distributed in the radial direction, a blowdown valve cavity which is communicated with the blowdown end of the valve ball is formed in the lower end of the middle of the valve body, and a blowdown plug is installed in the middle of the lower end of the blowdown valve cavity. The filter type floating ball valve is simple in structure, reasonable in design, convenient to operate and capable of reducing installation cost and saving installation space, filtering of impurities in a medium can be achieved, circulation of the medium and stopping of flowing of the medium can be achieved, the impurities can be effectively prevented from entering devices on the downstream of the valve, and the performance and the service life of the devices on the downstream of the valve are prevented from being influenced.
Description
Technical field
This patent belongs to valve field, relates to ball valve, especially a kind of filtering type floating ball valve.
Background technique
Common floating ball type is simple in structure, volume is little, lightweight, favorable sealing property, manufacture are easy to maintenance.But now common Float ball valve lacks filtrating equipment, and in the time containing impurity in medium, valve cannot be by filtration, cause impurity directly through valve passage, enter valve downstream device, and then affect its performance, reduce the life-span that uses pipeline.And when the circulation of the impurity in working condition requirement filter medium and control media with while closing, and on-the-spot installing space is limited, and filter and ball valve cannot be installed simultaneously.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art part, and a kind of filtering type floating ball valve of simple in structure, reasonable in design, convenient operation is provided.
The utility model solves its technical problem and takes following technological scheme to realize:
A kind of filtering type floating ball valve, comprise valve body, valve rod, valve ball, valve seat bracing ring and trim ring, valve body is shaped with horizontal medium channel, valve body middle part is longitudinally coaxially installed with valve rod, valve rod lower end Driven by Coaxial in valve body is provided with a valve ball, in the valve channel of these valve ball both sides, be all symmetrically installed with a valve seat bracing ring, the outer end of valve seat bracing ring is coaxially top-loaded with a trim ring, this trim ring is fixed on valve channel end by screw thread and compresses valve seat bracing ring, and valve seat insert is all radially installed between valve seat bracing ring and valve ball, it is characterized in that: described valve ball be provided with a T-shape passage, the outlet end of valve ball is fixed with a filter screen by multiple screws of radial equipartition, lower end, valve body middle part is shaped with the blowdown valve pocket being communicated with the blowdown end of valve ball, and it is stifled at middle part, blowdown valve pocket lower end, blowdown to be installed.
And, in the seating spring groove between described valve seat bracing ring and trim ring, multiple springs are radially installed; Between the outer wall of valve seat bracing ring and valve body, interval is provided with multiple sealing O type circles.
And, between the valve body on described valve rod top and valve body, filler is coaxially housed, in the valve body on this filler, be coaxially fixed with gland, valve rod upper end is stretched out gland and handle is installed.
Advantage of the present utility model and good effect are:
The utility model is simple in structure, reasonable in design, convenient operation, save installation cost, saved installing space, can meet the filtration of the impurity in medium and the demand that control media circulates and closes of realizing simultaneously, effectively prevent that impurity from entering valve downstream device, affects its performance and used life.
Accompanying drawing explanation
Fig. 1 is the utility model structural front view.
Embodiment
Below in conjunction with accompanying drawing and by specific embodiment, the utility model is described in further detail, and following examples are descriptive, are not determinate, can not limit protection domain of the present utility model with this.
A kind of filtering type floating ball valve, comprise valve body 6, valve rod 1, valve ball 5, valve seat bracing ring 7 and trim ring 8, valve body is shaped with horizontal medium channel, valve body middle part is longitudinally coaxially installed with valve rod, valve rod lower end Driven by Coaxial in valve body is provided with a valve ball, in the valve channel of these valve ball both sides, be all symmetrically installed with a valve seat bracing ring, the outer end of valve seat bracing ring is coaxially top-loaded with a trim ring, this trim ring is fixed on valve channel end by screw thread and compresses valve seat bracing ring, and valve seat insert 14 is all radially installed between valve seat bracing ring and valve ball.
For the preload pressure of maintaining valve seat supports circle, multiple springs 9 are radially installed in the seating spring groove between described valve seat bracing ring and trim ring.
For maintaining valve rod seal, between the valve body on described valve rod top and valve body, filler 3 is coaxially housed, in the valve body on this filler, be coaxially fixed with gland 2, valve rod upper end is stretched out gland and handle 4 is installed.
Between the outer wall of valve seat bracing ring and valve body, interval is provided with multiple sealing O type circles 10.
Innovative point of the present utility model is:
Take accompanying drawing 1 direction as example explanation, valve ball be provided with a T-shape passage, the left end of this valve channel is that entrance point, right-hand member are that outlet end, lower end are blowdown end, the outlet end of valve ball is fixed with a filter screen 11 by multiple screws of radial equipartition, lower end, valve body middle part is shaped with the blowdown valve pocket 12 being communicated with the blowdown end of valve ball, and at middle part, blowdown valve pocket lower end, blowdown stifled 13 is installed.
When valve opening, the impurity in medium is filtered net filtration, and it is in Action of Gravity Field drops to valve body lower end blowdown valve pocket, and the blowdown of can dismantling in the time of some that impurity is saved bit by bit is stifled, and impurity is discharged.
