Description
Technical field
This utility model relates to valve field, more specifically, it relates to a kind of manual knife-shape gate valve.
Background technology
Manual knife-shape gate valve is by the valve of compressed air-driven.Manual knife gate valve is exactly briefly to use handwheel rotary control valve, thus realizes the on an off of valve.It can be divided into upper and lower two parts, and top half is handwheel, and the latter half is valve.This class valve the most typically should be horizontally mounted.
Wherein handwheel is fixed on valve body by support; flashboard is driven realizing opening or Guan Bi by handwheel; but support generally uses steel plate bending to become U-shaped like shape; make screw pass support to be connected with the handwheel contiguous block of handwheel; bolt is installed so that support does not has enough spaces to tight a bolt for spanner from lower to upper; it is not easy to dismounting and installs; flashboard has enough strokes simultaneously; therefore support would generally be fabricated to elongate; the support of U-shape is also susceptible to deformation and bending so that handwheel cannot precisely realize driving.
Utility model content
The deficiency existed for prior art, the purpose of this utility model is to provide a kind of manual knife-shape gate valve, it is simple to install, and realizes precisely driving flashboard to move up and down simultaneously.
For achieving the above object, this utility model provides following technical scheme:
A kind of manual knife-shape gate valve, including valve body, flashboard, valve rod, support and handwheel, described flashboard is placed in valve body, one end of described support is connected with valve body, the other end of described support is provided with handwheel contiguous block, one end of described valve rod is connected with flashboard, and the other end is connected through handwheel contiguous block with handwheel, and left surface and the right flank of described handwheel contiguous block are equipped with support screwed hole；Described support is made up of two supporting plates, two supporting plates lay respectively at left surface and the right flank of handwheel contiguous block, the trapezoidal shape of described supporting plate, its big end is connected with valve body by bolt, and small end is by bolt being connected through support screwed hole and handwheel contiguous block.
This utility model is arranged further: the leading flank of described handwheel contiguous block and trailing flank are equipped with lobe outwardly, and described lobe also is provided with support screwed hole；Described supporting plate includes that the dual-side of supporting plate main body and supporting plate main body all stretches out and bending forms bracket fixture portions, and described bracket fixture portions matches with lobe, and bolt is through the fixing connection of support screwed hole of lobe.
This utility model is arranged further: described lobe and handwheel contiguous block use fillet excessive.
This utility model beneficial effect: handwheel can be fixed on support by handwheel contiguous block, described support is made up of two supporting plates, it is easy to support manufacture and installation, two supporting plates are separately fixed at left surface and the right flank of handwheel contiguous block, bolt is fixed on supporting plate on handwheel contiguous block through the support screwed hole of handwheel contiguous block, and bolt uses side to install so that spanner has sufficient space to tight a bolt, the trapezoidal shape of described supporting plate so that handwheel firmly installs stable.

Detailed description of the invention
1 to Fig. 5 manual knife-shape gate valve a kind of to this utility model is described in further details referring to the drawings.
A kind of manual knife-shape gate valve, including valve body 1, flashboard 2, valve rod 3, support 4 and handwheel 5, described flashboard 2 is placed in valve body 1, one end of described support 4 is connected with valve body 1, the other end of described support 4 is provided with handwheel contiguous block 6, one end of described valve rod 3 is connected with flashboard 2, and the other end is connected through handwheel contiguous block 6 with handwheel 5, and left surface and the right flank of described handwheel contiguous block 6 are equipped with support screwed hole 61；Described support 4 is made up of two supporting plates 41, two supporting plates 41 lay respectively at left surface and the right flank of handwheel contiguous block 6, the described trapezoidal shape of supporting plate 41, its big end is connected with valve body 1 by bolt, and small end passes being connected of support screwed hole 61 and handwheel contiguous block 6 by bolt.
Firmly installing stable to improve support 4, the leading flank of described handwheel contiguous block 6 and trailing flank are equipped with lobe 62 outwardly, and described lobe 62 also is provided with support screwed hole 61；Described supporting plate 41 includes that the dual-side of supporting plate 41 main body and supporting plate main body 411 all stretches out and bending forms bracket fixture portions 412, described bracket fixture portions 412 matches with lobe 62, bolt is through the fixing connection of support screwed hole 61 of lobe 62, reinforcement effect is played in the bending part of supporting plate 41 simultaneously, prevents supporting plate 41 from deforming distortion.
Described lobe 62 uses fillet excessive with handwheel contiguous block 6 so that handwheel contiguous block 6 can fit tightly with supporting plate 41, firmly installs stable.
Handwheel 5 can be fixed on support 4 by handwheel contiguous block 6, described support 4 is made up of two supporting plates 41, it is easy to support 4 manufacture and install, two supporting plates 41 are separately fixed at left surface and the right flank of handwheel contiguous block 6, bolt is fixed on handwheel contiguous block 6 through 61 supporting plates 41 of support screwed hole of handwheel contiguous block 6, and bolt uses side to install so that spanner has sufficient space to tight a bolt, the described trapezoidal shape of supporting plate 41 so that handwheel 5 firmly installs stable.
The above is only preferred implementation of the present utility model, and protection domain of the present utility model is not limited merely to above-described embodiment, and all technical schemes belonged under this utility model thinking belong to protection domain of the present utility model.It should be pointed out that, for those skilled in the art, without departing from the some improvements and modifications under this utility model principle premise, these improvements and modifications also should be regarded as protection domain of the present utility model.
