Abstract
It the utility model is related to a kind of pneumatic extension bar gate valve with segmentation structure valve rod.The pneumatic extension bar gate valve includes valve body, bonnet, flashboard, valve rod, it is characterised in that：Valve rod is formed by connecting by upper valve rod with lower valve rod by connector, the connector is made up of the connector of left and right two, connector has connecting portion and upper and lower two limiting sections, there is stopper slot between upper and lower two limiting sections, bottom of upper valve rod or so two is designed with upper groove on face, low groove is designed with the face of two, top of lower valve rod or so, two connectors, two limiting sections above are respectively placed in two upper grooves of upper valve rod.This pneumatic extension bar gate valve, because valve rod is segmented into upper valve rod and lower valve rod, is then realized and be connected by connector again, therefore whole valve rod is more firm, is more easily manufactured.
Description
Technical field
It the utility model is related to a kind of gate valve, and in particular to a kind of pneumatic extension bar gate valve.
Background technology
Because of the difference of field of employment, the overall height of some gate valves is very high, such as buried gate valve, and this gate valve needs to bury
In underground, therefore just very high for the overall height of gate valve, gate valve whole height uprises, corresponding valve rod also have it is elongated, so
And the elongated result brought of valve rod is that valve rod becomes easily broken, manufacture difficulty accordingly improves, and if valve rod somewhere goes wrong
Integral replacing is needed, is made troubles to user.
The content of the invention
In view of the shortcomings of the prior art, the utility model innovation provides a kind of gas with segmentation structure valve rod
Dynamic extension bar gate valve.The pneumatic extension bar gate valve includes valve body, bonnet, flashboard, valve rod, it is characterised in that：The valve rod by
Upper valve rod is formed by connecting with lower valve rod by connector, and the connector is made up of the connector of left and right two, and connector, which has, to be connected
Socket part and upper and lower two limiting sections, there are two faces of stopper slot, the bottom of the upper valve rod or so between upper and lower two limiting sections
On be designed with being designed with low groove on two faces of upper groove, the top of the lower valve rod or so, two connectors are above
Two limiting sections are respectively placed in two upper grooves of upper valve rod, and underlying two limiting sections of two connectors are respectively placed in
In two low grooves of lower valve rod, two connectors are bolted.
Also include pneumatic actuator, the pneumatic actuator includes cylinder block and piston, and the piston matching is set
Put in cylinder block, and be connected with valve rod, multiple springs are provided between the piston and the top of cylinder block, multiple springs are located at
Around valve rod, the top of the cylinder block is provided with the relief hole communicated with the inner chamber of cylinder block, and the bottom of the cylinder block is set
There is the air admission hole communicated with the inner chamber of cylinder block.
Spring base is provided with the piston, spring housing is provided with the spring base, the spring is arranged on spring housing
It is interior.
The cylinder block is made up of cylinder upper cover, cylinder main body and air cylinder base, and the cylinder upper cover is sealingly disposed in
The top of cylinder main body, the air cylinder base are sealingly disposed in the bottom of cylinder main body, and the cylinder upper cover leads to air cylinder base
Screw rod is crossed to achieve a fixed connection with nut.
According to a kind of pneumatic extension bar gate valve provided by the utility model, because valve rod is segmented into upper valve rod and lower valve rod,
Then realized and be connected by connector again, therefore whole valve rod is more firm, is more easily manufactured.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model；
Fig. 2 is the explosive view of valve rod of the present utility model and connector.
Embodiment
As shown in figs. 1 and 2, the pneumatic extension bar gate valve includes valve body, bonnet, flashboard, valve rod, and valve rod is by upper valve rod 1
It is formed by connecting with lower valve rod 2 by connector, the connector is made up of the connector 3 of left and right two, and connector 3 has connecting portion
30 with upper and lower two limiting sections 31, there are two faces of stopper slot 32, the bottom of upper valve rod 1 or so between upper and lower two limiting sections 31
On be designed with being designed with low groove 20 on two faces of upper groove 10, the top of lower valve rod 2 or so, two connectors 3 are above
Two limiting sections 31 be respectively placed in two upper grooves 10 of upper valve rod 1, two connectors, 3 underlying two limiting sections
31 are respectively placed in two low grooves 20 of lower valve rod 2, and two connectors 3 are connected by bolt 4.By said structure, entirely
Stem structure is more firm, and manufacture is also easier to, and structural issue occurs in valve rod somewhere, can replace that corresponding section
Valve rod, save maintenance cost.
As shown in Fig. 2 the pneumatic extension bar gate valve also includes pneumatic actuator, the pneumatic actuator includes gas
Cylinder body 7 and piston 11, the matching of piston 11 is arranged in cylinder block 7, and is connected with valve rod 8, and the top of cylinder block 7 is provided with and cylinder
The relief hole 70 that the inner chamber of body 7 communicates, the bottom of the cylinder block 7 are provided with the air admission hole 74 communicated with the inner chamber of cylinder block 7.
During work, source of the gas enters from air admission hole 74, and enters in cylinder block 7, and such gas just promotes piston 11 upward
Mobile, because piston 11 is connected with valve rod 8, therefore when piston 11 moves up, valve rod 8 also moves up therewith, on piston 11
The gas of side is just discharged from relief hole 70, and valve rod 8 takes up flashboard upwards like this, so as to realize valve opening.
In order to facilitate the manufacture and installation of cylinder block, cylinder block 7 of the present utility model is by cylinder upper cover 71, cylinder main body
72 and air cylinder base 73 form, cylinder upper cover 71 is sealingly disposed in the top of cylinder main body 72, the sealed set of air cylinder base 73
In the bottom of cylinder main body 72, cylinder upper cover 71 is achieved a fixed connection with air cylinder base 73 by screw rod and nut.By above-mentioned
Structure, the manufacture and installation of cylinder block 7 can be more beneficial for.
