Abstract
The utility model provides a hand wheel of a valve, which belongs to the technical field of machinery and resolves the problem that the existing hand wheel is not easy to be screwed caused by frictionbetween a hand wheel handle and a valve body. The hand wheel of a valve comprises a cylindrical hand wheel body, a prism body is arranged on the hand wheel body and is in the shape of polygon, and the center of the prism body coincides with that of the hand wheel body. A user can utilize tools such as spanners and the like to clamp the polygonal prism body on the handle wheel body to increase rotation torque, thereby saving labor during use. The bottom turned edge of the hand wheel body is provided with a notch, and the user can view rotation angle of the hand wheel directly through the notchand then deduces opening and closing conditions of a valve spool indirectly, thereby realizing convenient use and simple structure. In addition, the hand wheel can rotate by hands under conditions without spanners, the handle can rotate by two modes, and the hand wheel is simple in structure.
Description
Technical field
The utility model belongs to field of mechanical technique, relates to a kind of handwheel of valve.
Background technique
The handwheel of valve mainly is to be provided with very big handle in the market, directly utilizes the handle on the handwheel to come rotational valve core.
First kind of handwheel structure such as patent (200620132095) are disclosed, comprise the ring wheel rim that curves with hollow steel pipe or iron pipe, the center of wheel rim is provided with metal wheel hub, the wheel hub center has mounting hole, is connected with between ring wheel rim and wheel hub with the rammed tabular spoke that plays the stiffening rib effect of steel plate.
The handwheel of this structure has the handle of very big ring, and the user directly holds handle and rotates handwheel, and the application is more extensive.But shortcoming be between crank handles and the valve body because under the bigger situation of some reason frictional force, directly go to twist very effort, even may twist motionless with hand.Bring very big inconvenience to the user, particularly Low women and children.
Summary of the invention
The purpose of this utility model is the problems referred to above that exist at existing valve handle, provides a kind of spanner simple in structure, reasonable in design, available the afterburning valve handle that rotates.
The purpose of this utility model can realize by following technical proposal: a kind of handwheel of valve, comprise the handwheel main body of tubular, it is characterized in that described handwheel main body is provided with a prism, prism be shaped as polygonal, the center of prism overlaps with the center of handwheel main body.
The handwheel main body is installed on the valve body and with spool and axially is being connected and can swaying synchronously, after handwheel drive is rotated by external force, drives spool and rotates together, makes whole valve opening or closes.Because the consideration on sealing and the safety, very big frictional force is often arranged between handwheel, spool and the valve body, cause handwheel very tight when rotating, generally twisting with hand can be more painstaking, polygonal prism on this handwheel main body can be clamped with spanner, hold on spanner and rotate, just increased the moment that handwheel rotates, can be with rotating the handwheel spool relative to less power.
In the handwheel of above-mentioned a kind of valve, described prism be shaped as regular hexagon.It all is interior hexagonal generally a lot of telescopic spanners being arranged on the market, and it is more extensive that prism is made the regular hexagon applicable situation.
In the handwheel of above-mentioned a kind of valve, respectively there is a handle described handwheel main body both sides.Handwheel rotates at the handle that can grasp both sides in the situation without spanner.
In the handwheel of above-mentioned a kind of valve, described handwheel bottom part body is provided with a flange, and two breach are arranged on this flange, and breach is distributed in the both sides of handwheel main body and staggers with handle.Be provided with graduation line with the corresponding valve body of breach on the flange, when handwheel rotates, can see by breach how many angles handwheel has turned over, just can infer the folding situation of spool accordingly.
In the handwheel of above-mentioned a kind of valve, there is a hole to be through to handwheel main body inner chamber on the described prism.The handwheel main body is provided with the hole that a screw passes on the prism handwheel main body and spool is fixed together.
Compared with prior art, this device has following advantage:
1, the user can use stop polygonal prism on the wheel body of tool holder such as spanner to increase the moment of rotation, uses laborsaving.
2, jagged on the handwheel bottom part body flange, can directly find out the angle that handwheel rotates, the indirect folding situation of inferring spool, easy to use, simple in structure.
3, do not having to use the hand rotatory handling to realize under the situation of spanner yet, two kinds of handle with sleeve modes, simple in structure.
Description of drawings
Fig. 1 is the sectional arrangement drawing structural representation of handwheel valve body.
Fig. 2 is the assembling plan view structural representation of handwheel valve body.
Fig. 3 is the perspective view of handwheel.
Among the figure, 1, the handwheel main body; 2, prism; 3, handle; 4, flange; 5, breach; 6, hole; 7, valve body; 8, spool; 9, screw.
Embodiment
As Fig. 1, shown in Figure 3, the handwheel of this valve comprises the handwheel main body 1 that is arranged on the valve body 7, and this handwheel main body 1 can be rotated mutually with valve, and its both sides respectively are provided with a handle 3, and the user can grasp handle 3 handwheel is rotated.Handwheel main body 1 is provided with an orthohexagonal prism 2, prism 2 is provided with a hole 6 and is through to handwheel main body 1 inner chamber, also be provided with the hole 6 that a screw 9 passes on the prism 2 on this handwheel main body 1 handwheel main body 1 and spool 8 are fixed together, spool 8 rotated synchronously when handwheel main body 1 was rotated.As shown in Figure 2, the bottom of handwheel main body 1 is provided with a flange 4, has two breach 5, breach 5 to be distributed in the both sides of handwheel main body 1 on this flange 4 and does not overlap with handle 3.Be provided with graduation line with the 5 corresponding valve bodies 7 of breach on the flange 4.When handwheel rotates, can see by breach 5 how many angles handwheel has turned over, just can infer the folding situation of spool 8 accordingly.Particularly rigidly connecting does not need to do test more and just can know that this valve opens or close when the user who touches uses, very convenient.
When valve in use needs to open or close, grasp the handle 3 of both sides or clamp orthohexagonal prism 2 rotation handwheels with spanner, handwheel drives spool 8 and rotates synchronously, can control the rotation angle of spool 8 by the graduation line on the breach 5 contrast valve bodies 7, cut off or connect the fluid in the pipeline.
