Description
Technical field
The utility model belongs to valve technology field, the handwheel that uses on particularly a kind of valve.
Background technique
On valve, generally need a handwheel, be used for the operation that valve is opened or closed.After valve was installed on pipeline, it mainly acts on was the break-make of pilot line.But sometimes, also be necessary to come the flow of fluid in the pilot line, with dealing with various requirements by valve.Existing valve all is that operator's at one's discretion feel and experience finished when the flow of pilot line fluid.Like this, the flow of pipeline just is difficult to be accurately controlled, and the deviation of appearance is bigger, can cause the wasting phenomena of the energy and resource.
At present, all do not occur having the digital hand wheel or the handle of scale on the valve that people produced and used, do not meet relevant patent documentation or technical data yet.Certainly, the handwheel that has scale also has, and as " a kind of tube bender handwheel screw with calibration " that Chinese patent 982198345 provides, it is controlled during to the metal tube bending at tube bender and designs.Obviously, it is not to be used for valve, and is different fully with purpose of the present invention yet.
Summary of the invention
The purpose of this utility model is at this problem of the existing accurately control flow rate of the handwheel of valve, provide a kind of simple in structure, easy to operate, practical valve digital hand wheel, to reach the fluid flow of controlling scientificly, reasonably and accurately by valve.
The purpose of this utility model realizes by following technical proposal: this valve comprises the body that a valve rod that is used for valve is connected with digital hand wheel, this handwheel also comprises the main digit wheel that a valve body that is used for valve is connected, main digit wheel is socketed on the body, and the front of main digit wheel indicates the scale sign.
When being applied to valve, body and valve rod are connected this valve with digital hand wheel, and main digit wheel and valve body are connected.In the handwheel rotation process, main digit wheel is fixed, and body rotates with valve rod.By the scale sign of main digit wheel, just can determine the angle that handwheel rotates, thereby the control fluid is by the flow of valve.
With in the digital hand wheel, a case is set in handwheel preferably at above-mentioned valve, case and body are fixed together, and body and main digit wheel all are positioned at case.Case has been arranged, and the operator of valve in fact is by rotating case, body and valve rod being rotated.
If case has covered the front of whole main digit wheel, normally open an indicating window over against the position of main digit wheel scale sign this moment on case.Can read the rotation angle of handwheel by indicating window.
Use in the digital hand wheel at above-mentioned valve, sidepiece at main digit wheel also can be provided with digit wheel one time, inferior digit wheel is socketed in the rotating shaft that is connected with body, there is the scale sign in the front of inferior digit wheel, there are several teeth the side of inferior digit wheel, have teeth at least in the side of main digit wheel, main digit wheel is meshed by teeth with time digit wheel.
In rotating the handwheel process, inferior digit wheel also rotates along with body, and main digit wheel is motionless.By main digit wheel and the teeth that time digit wheel side is meshed, time digit wheel is rotated with respect to body.
Set up inferior digit wheel in main digit wheel side, improved the function and the performance of this digital handwheel.Particularly, if the side of main digit wheel is teeth, when body rotates a circle, main digit wheel will drive time digit wheel and rotate a tooth position with respect to body so.Therefore, the scale sign of number of pass times character wheel can be understood the rotation number of turns of handwheel.In another case, the teeth of promptly main digit wheel side are more than the teeth of time digit wheel, the several times of time digit wheel teeth preferably, and so, when body rotated a circle, inferior digit wheel just rotated greater than one with respect to body and encloses or a few angle.At this moment, the number of pass times character wheel can reflect the rotation angle of body more accurately, has improved the precision of this digital handwheel.
, be located at usually in the case at situation digit wheel next time that case is arranged with in the digital hand wheel at above-mentioned valve, the rotating shaft at inferior digit wheel center is fixed in the case.If case has covered the front of whole digit wheel, can also on case, open an indicating window over against the position of inferior digit wheel graduated scale will.Understand the indicated value of time digit wheel by indicating window.
Compared with prior art, this valve is with the advantage of digital hand wheel:
1, owing to adopted main digit wheel to represent the rotation angle of handwheel, energy is reading, the flow of fluid in the pilot line scientifically and rationally intuitively.
2, by time digit wheel is set, increase the function and the performance of this digital handwheel, can more accurately show the rotation angle or the number of turns of handwheel, and also very convenient to adjusting by the fluid flow size of valve.
3, in rotating the handwheel process, main digit wheel and time digit wheel can automatic readings, and be simple to operate, on the valves such as available various types of stop valves, gate valve, ball valve, hot-water heating.Adopt the valve of this digital handwheel can be widely used in industries such as oil, rock gas, colliery, chemical industry, plumbing, air feed, water supply, very high use value is arranged at energy saving and resource, aspect such as reduce cost.

Embodiment
As shown in Figure 1, in the present embodiment, the valve digital hand wheel is made up of body 1, main digit wheel 2, inferior digit wheel 3, case 4.Body 1 is cylindrical, and main digit wheel 2 is socketed on the body 1.The inner side surface of body 1 is provided with teeth 11, is beneficial to be connected with valve rod 6.
As shown in Figure 3, when this valve was applied to gate valve with digital hand wheel, body 1 was placed on the valve rod 6, and by the teeth 11 of body 1 inner side surface body 1 and valve rod 6 was connected.2 valve bodies 5 with gate valve of main digit wheel are connected.Obviously, in rotating the handwheel process, main digit wheel 2 is motionless.
As shown in figures 1 and 3, in the present embodiment, time digit wheel 3 is set at the sidepiece of main digit wheel 2., 16 teeth 32 are arranged in the side of inferior digit wheel 3, and have only teeth 22 to shown in Figure 8 as Fig. 4, and be meshed by teeth 22,32 between main digit wheel 2 and the inferior digit wheel 3 in the side of main digit wheel 2.Therefore, moving main digit wheel 2 one circles of revolution are stirred time digit wheel 3 by the teeth 22 of main digit wheel 2, can make time digit wheel 3 rotate a tooth position.
As Fig. 4, Fig. 5 and shown in Figure 6, indicate scale sign 21 in the front of main digit wheel 2.In the present embodiment, the scale sign 21 on the main digit wheel 2 is 0 to 90 numeral and some graduation lines.As shown in Figure 2, the position corresponding to this graduated scale will 21 has an indicating window 41 on case 4.Utilize indicating window 41 can observe and read scale value, to understand the rotation angle of handwheel.
As shown in Figure 7 and Figure 8, in the front of inferior digit wheel 3 the scale sign 31 that is similar to main digit wheel 2 is arranged also.The scale sign 31 here is 0 to 150 six numeral and some graduation lines.As shown in Figure 2, same on case 4 position corresponding to this graduated scale will 31 have an indicating window 41.By this indicating window 41, can understand the rotation number of turns of handwheel.
After this handwheel was applied to gate valve, the indicated different scale values of two indicating windows 41 will be corresponding to the different opening degree of gate valve on the case 4, make the operator accurately in the pilot line fluid by the flow of gate valve.
