Description
Technical field
The utility model is related to oil production equipment fields, and in particular to a kind of manual flat valve.
Background technology
In domestic and international existing petrochemical equipment, flap type is all single type of drive；I.e.：Or handwheel driving or
Hydraulic-driven or motor driving or air pressure driving.In addition to handwheel drives, other type of drive are required to an auxiliary system
System is, it is necessary to there is precondition；If auxiliary system goes wrong or precondition missing, the pipe of entire flap type control will be made
Road or equipment just can not be run.
For some important pipelines or equipment, it can not run and mean that heavy economic losses or security incident.It is existing
The solution for ensuring operation is typically " bivalve configuration "：I.e. near the valve automatically controlled, a hand control valve of connecting；
If complicated pipeline or equipment, then using more autocontrol valves, while configure more hand control valves；This not only increases
The volume and weight of pipeline or equipment, and also increase the cost of investment of user.
Utility model content
The technical problems to be solved in the utility model is to have overcome the deficiencies of the prior art and provide a kind of manual flat valve,
Improve the stress of valve plate by the self-regulation structure of connection sliding block and valve plate, improve the service life of valve plate, Jin Erti
The service life of high entire valve body and security, reduce equipment investment cost.
In order to achieve the above objectives, the technical solution adopted in the utility model is：A kind of manual flat valve, including bonnet,
Bottom flange, valve body, foot piece component, adjustment member, built-in valve seat, upper valve rod, valve plate and lower guide rod；The bonnet, and bottom flange
The upper side and lower side of valve body is separately fixed at, the foot piece component is arranged on bottom flange, and the adjustment member is arranged on upper valve
It covers, the built-in valve seat is fixed in the middle part of valve body, and the valve plate is arranged in built-in valve seat, and the upper valve rod is arranged on flashboard
On, the lower guide rod is fixed on the downside of flashboard；The top of the upper valve rod is connected with adjustment member, and the lower part of the lower guide rod is inserted
Enter foot piece component internal.
It is further improved as the utility model, connection sliding block is equipped between the valve plate and upper valve rod；Connection sliding block
In embedded valve plate, it is connected between upper valve rod using axis pin mode.
It is further improved as the utility model, connection sliding block is equipped between the valve plate and lower guide rod；Connection sliding block
In embedded valve plate, it is connected between lower guide rod using axis pin mode.
Further improved as the utility model, the top and bottom of the valve plate are respectively equipped with T-shaped sliding slot, the T-shaped
Sliding slot is straight slot；The maximum width of the T-slot cross section is 1.5 times~1.8 times of minimum widith.
Due to the utilization of above-mentioned technical proposal, the utility model has following advantages compared with prior art：
Improve the stress of valve plate by the self-regulation structure of connection sliding block and valve plate, that improves valve plate uses the longevity
Life, and then service life and the security of entire valve body are improved, reduce equipment investment cost.

Specific embodiment
With reference to specific embodiment, the utility model is described in further detail.
A kind of manual flat valve as shown in Figure 1 to Figure 3, including bonnet, 2, bottom flange 4, valve body 3, foot piece component 5, tune
Whole component 1, built-in valve seat 7, upper valve rod 6, valve plate 8 and lower guide rod 9；Bonnet, 2 and bottom flange 4 are separately fixed at the upper of valve body 3
End and lower end, carrying basis of the bonnet, 2 as adjustment member 1, carrying basis of the bottom flange 4 as foot piece component 5.
Adjustment member 1 includes rotating handles and elevating mechanism, and rotating rotating handles can drive elevating mechanism to drive valve plate 8
It moves up and down.
Foot piece component 5 is equipped with hood set and lower guide sleeve, and lower guide sleeve is fixed in hood set, and lower guide rod is arranged on lower guide sleeve
It is interior and move up and down in lower guide sleeve.
Bonnet, 2 and bottom flange 4 are separately fixed at the upper side and lower side of valve body 3, and foot piece component 5 is arranged on bottom flange 4,
Adjustment member 1 is arranged on bonnet, 2；Built-in valve seat 7 is fixed on 3 middle part of valve body, and valve plate 8 is arranged in built-in valve seat 7, upper valve
Bar 6 is arranged on flashboard 8, and lower guide rod 9 is fixed on the downside of flashboard 8；The top of upper valve rod 6 is connected with adjustment member 1, lower guide rod
