Abstract
The utility model belongs to the technical field of the choke valve technique and specifically relates to a rotary indicator structure of choke valve. The utility model provides a rotatory indicator structure of choke valve, includes hand wheel, indicator cover, its characterized in that: the lower part of the hand wheel is connected with an indicator inner sleeve through a bolt, and the lower part of the indicator inner sleeve is connected with a valve rod extension rod through a valve rod nut; the top of the valve rod extension bar penetrates through the indicator inner sleeve and is connected with the indicator outer sleeve. Compared with the prior art, the rotary indicator structure of the throttle valve is provided, when the flow is adjusted, the flow of the specific working state of the throttle valve can be accurately controlled according to scale display, and the working precision of the throttle valve is improved.
Description
Technical Field
The utility model belongs to the technical field of the choke valve technique and specifically relates to a rotary indicator structure of choke valve.
Background
The flow of the common throttle valve is roughly adjusted by an operator according to experience, and an accurate device is not provided for the operator to refer, so that the flow of the throttle valve is inconsistent during each work, and the working state is influenced.
Disclosure of Invention
The utility model discloses an overcome prior art not enough, provide a rotary indicator structure of choke valve, when its adjustment flow size, can show according to the scale, the flow of the concrete operating condition of its choke valve of accurate control provides the work precision of choke valve.
In order to realize above-mentioned purpose, design the rotatory indicator structure of a choke valve, including hand wheel, indicator cover, its characterized in that: the lower part of the hand wheel is connected with an indicator inner sleeve through a bolt, and the lower part of the indicator inner sleeve is connected with a valve rod extension rod through a valve rod nut; the top of the valve rod extension bar penetrates through the indicator inner sleeve and is connected with the indicator outer sleeve.
The lower part equipartition of valve rod extension bar be equipped with the screw thread to valve rod nut is passed through threaded connection to the lower part of valve rod extension bar.
The upper portion cover of indicator endotheca be equipped with the indicator, be located the outside cover of indicator and be equipped with the indicator overcoat.
The top of the inner side of the indicator outer sleeve is connected with the top of the valve rod extension rod.
Compared with the prior art, the utility model, a rotation indicator structure of choke valve is provided, when its adjustment flow size, can show according to the scale, the flow of the concrete operating condition of its choke valve of accurate control provides the work precision of choke valve.
Through the rotation of valve rod extension bar to drive the removal of indicator cover, thereby follow and show its flow size, whole action process, its accurate flow size of simple, clear demonstration promotes the work precision.
Drawings
Fig. 1 is a perspective view of the structure of the present invention.
Fig. 2 and fig. 3 are sectional views of the structure of the present invention.
Referring to fig. 1 to 3, 1 is an indicator outer sleeve, 2 is a hand wheel, 3 is a valve rod extension bar, 4 is a valve rod nut, 5 is an indicator inner sleeve, and 6 is an indicator.
Detailed Description
The invention will be further described with reference to the accompanying drawings.
As shown in fig. 1 to 3, the lower part of the hand wheel 2 is connected with an indicator inner sleeve 5 through a bolt, and the lower part of the indicator inner sleeve 5 is connected with a valve rod extension rod 3 through a valve rod nut 4; the top of the valve rod extension bar 3 penetrates through the indicator inner sleeve 5 and is connected with the indicator outer sleeve 1.
The lower part equipartition of valve rod extension bar 3 is equipped with the screw thread to threaded connection valve rod nut 4 is passed through to the lower part of valve rod extension bar 3.
The upper part of the indicator inner sleeve 5 is sleeved with an indicator 6, and the outer side of the indicator 6 is sleeved with the indicator outer sleeve 1.
The top of the inner side of the indicator outer sleeve 1 is connected with the top of the valve rod extension bar 3.
The during operation, when the mobile size of needs adjustment, the operative employee only need twist reverse hand wheel 2 with the hand, hand wheel 2 passes through the bolt and drives indicator endotheca 5, thereby it is rotatory to drive valve rod extension bar 3, the top and the indicator overcoat 1 of valve rod extension bar 3 are connected, thus, clockwise and anticlockwise rotation through hand wheel 2, thereby reciprocating of control indicator overcoat 1, because the upper portion cover of indicator endotheca 5 is equipped with indicator 6, direct display flow scale on the indicator 6, it is simple, clear its accurate flow size of demonstration, promote the work precision.
