Abstract
The utility model discloses a kind of novel pneumatic butterfly valve, including pneumatic actuator and valve body, the connection boss being integrated with valve body is equipped at the center of the top end of the valve body, pneumatic actuator is fixedly connected with boss is connect；The utility model makes the integrated harmony and sealing performance of valve body and pneumatic actuator when being fixedly connected with performance even closer effective use of valve body and pneumatic actuator more preferable by being provided with the connection boss being integrated with valve body at the center of top end of the valve body, and reduces the production cost of Pneumatic butterfly valve.
Description
Technical field
The utility model relates to a kind of ball valve, specifically a kind of novel pneumatic butterfly valve.
Background technique
Butterfly valve is called flap valve, is a kind of simple regulating valve of structure, can be used for the switch control of low pressure pipeline medium
Butterfly valve refers to that closure member (flap or butterfly plate) is disk, and a kind of valve of open and close is reached around valve shaft rotation.Pneumatic butterfly
Valve includes pneumatic actuator, valve body, spool, and the connection of pneumatic actuator and valve body in Pneumatic butterfly valve in the prior art is logical
Connecting bracket is crossed to be fixedly connected, or by being fixedly connected pneumatic actuator and valve body by isolation frame.This connection
Fixed form has many disadvantages, is fixedly connected with mode by connecting bracket or isolation frame；The first, the system of connecting bracket
Higher cost is made, so that the manufacturing cost of entire Pneumatic butterfly valve increases.The second, more connecting components with regard to it is more together plus
Work and assembly process, reduce production efficiency.Third, pneumatic actuator pass through connecting bracket or frame are isolated with valve body to be fixed
It connecting, the rotary shaft in pneumatic actuator needs to transfer by vertically disposed coupling lever with the intracorporal valve rod of valve to be more troublesome,
Simultaneously will affect entire Pneumatic butterfly valve using when pneumatic actuator integrated harmony synchronous with valve body.
Utility model content
The mesh of the utility model is to provide a kind of novel pneumatic butterfly valve, to solve mentioned above in the background art ask
Topic.
To achieve the above object, the utility model provides the following technical solutions:
A kind of novel pneumatic butterfly valve, including pneumatic actuator and valve body, are equipped at the center of the top end of the valve body and valve body
The connection boss being integrated, pneumatic actuator are bolted to connection with boss is connect, and the inside middle of the valve body is perpendicular
Valve rod is directly installed, the center of valve body is equipped with spool, and spool connect the center for being mounted on valve body with valve rod；The utility model passes through
It is provided with the connection boss being integrated with valve body at the center of top end of the valve body and makes being fixedly connected for valve body and pneumatic actuator
The integrated harmony and sealing performance of valve body and pneumatic actuator are more preferable when performance even closer effective use, and reduce pneumatic
The production cost of butterfly valve.
Preferably, the top of the valve rod is connected with the rotary shaft in pneumatic actuator；Valve rod and pneumatic actuator
Interior rotary shaft is directly connected to so that valve body and pneumatic actuator synchronous coordination performance are good when in use.
Preferably, the valve rod and body wall junction are additionally provided with anti-static device.
Preferably, the valve body is using UPVC plastics or CPVC plastics or PPH plastics or PVDF plastics or FRPP plastics
It is made.
Compared with prior art, the utility model has the beneficial effects that first, pass through at the center of top end of the valve body be arranged
Have the connection boss being integrated with valve body make valve body and pneumatic actuator to be fixedly connected with performance even closer.
The second, the production cost of Pneumatic butterfly valve is reduced, connecting bracket and coupling lever are removed, so that the rotation in pneumatic actuator
Shaft can be directly connected to the intracorporal valve rod of valve, and pneumatic actuator and valve body integrated synchronous coordination performance are good, improve ball valve
Service performance.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model；
In figure: 1. valve bodies, 101. connection boss, 2. pneumatic actuators, 3. valve rods, 4. spools.
Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
Every other embodiment obtained, fall within the protection scope of the utility model.
The present embodiment is a kind of novel pneumatic butterfly valve, including pneumatic actuator 2 and valve body 1 as shown in Figure 1:, and valve body 1 pushes up
The connection boss 101 being integrated with valve body 1 is equipped at the center at end, pneumatic actuator 2 is bolted with boss 101 is connect
Connection, the inside middle of the valve body 1 is vertically-mounted valve rod 3, and the center of valve body 1 is equipped with spool 4, and spool 4 and valve rod 3 connect
Connect the center for being mounted on valve body 1；The top of valve rod 3 is connected with the rotary shaft (not shown) in pneumatic actuator 2；Valve rod 3
Be directly connected to the rotary shaft (not shown) in pneumatic actuator 2 so that when in use valve body 1 it is synchronous with pneumatic actuator 2 association
Tonality can be good；Valve rod 3 and 1 side wall junction of valve body are additionally provided with anti-static device；Valve body 1 uses UPVC plastics or CPVC plastics
Or PPH plastics or PVDF plastics or FRPP plastic production form.
The working principle of the utility model is: as shown in Figure 1: by being provided at the center on 1 top of valve body and valve body 1
The connection boss 101 being integrated be fixedly secured to one another valve body can by connecting boss 101 directly with pneumatic actuator 2,
It is even closer to be connected and fixed performance, pneumatic actuator 2 is more preferable in integrated synchronous harmony with valve body 1 at runtime, reduces simultaneously
The production cost of Pneumatic butterfly valve, improves production efficiency；Spool 4 is connect with vertically-mounted valve rod 3, in pneumatic actuator 2
Rotary shaft (not shown) be connected with valve rod 3；Therefore in use, valve body 1 is integrated with pneumatic actuator 2, valve body and gas
Dynamic actuator is fixedly connected with that performance is even closer, and synchronous coordination performance is good, reduces the production cost of Pneumatic butterfly valve.
It is obvious to a person skilled in the art that the present invention is not limited to the details of the above exemplary embodiments, and
And without departing substantially from the spirit or essential attributes of the utility model, it can realize that this is practical new in other specific forms
Type.Therefore, in all respects, the present embodiments are to be considered as illustrative and not restrictive, this is practical new
