Abstract
The utility model discloses a pneumatic diaphragm valve, including cylinder and valve body, the cylinder includes air cylinder upper cover, cylinder shell and bottom, and inside spring and the piston of being provided with of cylinder, the piston passes through the connecting piece to be connected with the bottom, and the inner wall of piston sliding connection at the cylinder, there are case and diaphragm in the bottom bottom through pin fixed mounting, the valve body sets up the bottom at the bottom, be provided with piston O type circle between connecting piece and the bottom, the bottom is provided with bottom O type circle and wear -resisting cover with the junction of piston, the bottom passes through nut and valve body fixed connection, this pneumatic diaphragm valve, its adopts and to be provided with a cylinder at the valve body top, through linear motion about the cylinder control piston to taking movable valve element and diaphragm up -and -down motion, realizing valve body open -closed state's conversion, in addition, piston O type circle and bottom O type circle help improve equipment's wearability, and the practicality is strong, easily uses widely.
Description
Technical field
The utility model is related to pneumatic operated valve equipment technical field, specially a kind of pneumatic diaphragm valve.
Background technology
Pneumatic diaphragm valve is a kind of block valve of special shape, comes across the twenties in 20th century.Its opening and closing element is one piece
With barrier film made by soft material, body cavity is separated with valve gap inner chamber and driver part, therefore claim pneumatic diaphragm valve.It is pneumatic every
Film valve most outstanding feature is that barrier film separates lower body inner chamber with upper valve cap inner chamber, makes valve rod, the valve for being located at diaphragm
The parts such as lobe do not receive dielectric corrosion, eliminate packing seal structure, and will not produce medium leakage.At present, it is common it is pneumatic every
Film valve arrangement is simple, and wearability is poor, affects service life, and does not generally possess cylinder and need manually operated, wastes time and energy.
The content of the invention
Prior art is difficult to meet the needs of people, in order to solve above-mentioned problem, the utility model proposes one
Pneumatic diaphragm valve is planted, it controls piston and move along a straight line up and down using a cylinder is provided with body top by cylinder, so as to
Band movable valve plug and diaphragm move up and down, and realize the conversion of valve body open and-shut mode.
For achieving the above object, the utility model provides following technical scheme：A kind of pneumatic diaphragm valve, including cylinder and valve
Body, the cylinder includes cylinder upper cover, cylinder shell and bottom, and cylinder interior is provided with spring and piston；The piston is by connecting
Fitting is connected with bottom, and piston is slidably connected at the inwall of cylinder；The bottom bottom is installed with valve element by pin
And diaphragm；The valve body is arranged on the bottom of bottom.
Further, piston O-ring is provided between the connector and bottom.
Further, the bottom is provided with bottom O-ring and wear-resistant sleeve with the junction of piston.
Further, the bottom is fixedly connected with the valve body by nut.
Compared with prior art, the beneficial effects of the utility model are：The pneumatic diaphragm valve, it adopts and is set in body top
A cylinder is equipped with, piston is controlled by cylinder and is moved along a straight line up and down, so as to band movable valve plug and diaphragm move up and down, realize valve body
The conversion of open and-shut mode, in addition, piston O-ring and bottom O-ring are favorably improved the wearability of equipment, it is practical, it is easy to
Promote the use of.

Specific embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is carried out
Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of the utility model, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment for being obtained, belongs to the scope of the utility model protection.
Refer to Fig. 1, a kind of embodiment that the utility model is provided：A kind of pneumatic diaphragm valve, including cylinder 1 and valve body 2,
The cylinder includes cylinder upper cover 3, cylinder shell 4 and bottom 5, and cylinder 1 is internally provided with spring 6 and piston 7；The piston 7 leads to
Cross connector 8 to be connected with bottom 5, and piston 7 is slidably connected at the inwall of cylinder 1；The bottom of the bottom 5 is fixed by pin 9
Valve element 10 and diaphragm 11 are installed；The valve body 2 is arranged on the bottom of bottom 5；It is provided between the connector 8 and bottom 5
Piston O-ring 12；The bottom 5 is provided with bottom O-ring 13 and wear-resistant sleeve 14 with the junction of piston 7；The bottom 5 passes through
Nut 15 is fixedly connected with valve body 2.
The utility model pneumatic diaphragm valve when in use, the diaphragm valve is installed, and controls piston 7 by cylinder 1 downward
Motion, moves downward valve element 10 and diaphragm 11, props up the lower wall of valve body 2, seals valve body 2, if valve body opened, only needs behaviour
Control cylinder 1 makes valve element 10 and diaphragm 11 travel upward and out the lower wall of valve body 2.
It is obvious to a person skilled in the art that the utility model is not limited to the details of above-mentioned one exemplary embodiment, and
And in the case of without departing substantially from spirit or essential attributes of the present utility model, can in other specific forms realize that this practicality is new
