Abstract
The utility model discloses a kind of Novel air dynamic formula butterfly valve, including pneumatic actuator and valve body, valve rod and flap are provided with valve body, the lower end of valve rod is connected with flap, and the upper end of valve rod passes valve body, is connected with pneumatic actuator；Copper sheathing is configured with the top of valve rod, the outer wall of copper sheathing is adapted with valve body；O-ring seal is provided between copper sheathing and valve rod；The detent of annular is circumferentially offered in the inwall of copper sheathing, the O-ring seal is arranged in detent.The beneficial effects of the utility model are：The sealing ring in former valve body is replaced using copper sheathing, the intensity and hardness of copper sheathing are higher, and wearability is preferable, during pneumatic type butterfly valve frequent switching, copper sheathing abrasion is smaller, and rotary valve rod can be made to be accurately positioned in valve body, prevent valve rod stuck, extend the service life of butterfly valve.
Description
Technical field
The utility model is related to valve technology field, and in particular to a kind of Novel air dynamic formula butterfly valve.
Background technology
The valve rod of pneumatic type butterfly valve adds itself frequent rotation at work due to bearing certain load for a long time, valve rod with
Easily deviate between valve seal position, produce larger gap, thus gap directly leaks out valve to the medium in valve, it is impossible to
Meet production requirement；And the off-center position of valve rod, it is stuck when easily causing valve opening or closing, reduce the use longevity of valve
Life.Therefore, it is necessary to be improved to prior art.
The content of the invention
The purpose of this utility model is, for existing deficiency, there is provided a kind of accurate positioning, good sealing effect it is new
Pneumatic type butterfly valve.
The technical solution adopted in the utility model is：A kind of Novel air dynamic formula butterfly valve, including pneumatic actuator and valve body, valve
Valve rod and flap are provided with vivo, the lower end of valve rod is connected with flap, and the upper end of valve rod passes valve body, with pneumatic actuator phase
Even；Copper sheathing is configured with the top of valve rod, the outer wall of copper sheathing is adapted with valve body.
By such scheme, O-ring seal is provided between copper sheathing and valve rod.
By such scheme, the detent of annular is circumferentially offered in the inwall of copper sheathing, the O-ring seal is arranged on fixed
In the groove of position.
By such scheme, interval offers upper and lower two groups of detents on copper sheathing, and the interior configuration one of each detent is O-shaped
Sealing ring.
The beneficial effects of the utility model are：
1st, the sealing ring in former valve body is replaced using copper sheathing, the intensity and hardness of copper sheathing are higher, wearability is preferable, in gas
During dynamic formula butterfly valve frequent switching, copper sheathing abrasion is smaller, and rotary valve rod can be made to be accurately positioned in valve body, prevents valve rod card
Extremely, the service life of butterfly valve is extended；Copper sheathing is built-in with O-ring seal, improves valve seal performance, it is therefore prevented that medium is let out
Dew, it is ensured that the safe and stable work of butterfly valve；
2nd, the utility model simple structure, it is easy for installation, it is practical.
Brief description of the drawings
Fig. 1 is one structural representation of specific embodiment of the utility model.
Fig. 2 is the left view of Fig. 1.
Wherein：1st, pneumatic actuator；2nd, valve body；3rd, valve rod；4th, flap；5th, copper sheathing；6th, O-ring seal.
Specific embodiment
In order to more fully understand the utility model, further is made to the utility model with specific embodiment below in conjunction with the accompanying drawings
Ground description.
Valve is provided with a kind of Novel air dynamic formula butterfly valve as shown in Figure 1, including pneumatic actuator 1 and valve body 2, valve body 2
Bar 3 and flap 4, the lower end of valve rod 3 are connected with flap 4, and the upper end of valve rod 3 passes valve body 2, is connected with pneumatic actuator 1；In valve
The top of bar 4 is configured with copper sheathing 5, and inwall and the outer wall of valve rod 4 of copper sheathing 5 are adjacent to, and the outer wall of copper sheathing 5 is adapted with valve body 2；
O-ring seal 6 is provided between copper sheathing 5 and valve rod 3；The detent of annular, the O are circumferentially offered in the inwall of copper sheathing 5
Type sealing ring 6 is arranged in detent.In the present embodiment, interval offers upper and lower two groups of detents on copper sheathing 5, and each is determined
One O-ring seal 6 of configuration in the groove of position.
In the present embodiment, copper sheathing 5 makes according to the inner wall size of valve body 2 and the dimensioned of valve rod 3；Copper sheathing 5 and O-shaped close
Seal 6 can effectively position with sealed valve stem 3, solve the problems, such as that pneumatic type butterfly valve is stuck and medium leakage, reduce pneumatic type butterfly
The fault rate of valve；Meanwhile, improve the life-span of pneumatic type butterfly valve.
Preferred embodiment of the present utility model is the foregoing is only, the utility model is not limited to.Previous embodiment
The utility model is described in detail, for a person skilled in the art, it still can be to foregoing each implementation
Technical scheme described in example is modified, or carries out equivalent to which part technical characteristic.In every case it is new in this practicality
Within the scope of the inventive concept of type, any modification, equivalent substitution and improvements done etc. are all contained in protection of the present utility model
Within the scope of.
