Description
Technical Field
The utility model relates to a lift rod formula valve technical field, in particular to lift rod formula valve switch indicating device.
Background
The lifting rod type valve comprises a gate valve, a stop valve, a track type ball valve and other types of valves, and the common characteristics of the lifting rod type valve and the stop valve are that a gate plate is lifted through a lifting valve rod or a valve core is rotated to realize the opening and closing functions of the valve, and the operation modes of the valves mainly comprise manual operation, electric operation, pneumatic operation and the like.
For manually operated valves, during the actual opening and closing process we find: the old indicating rod has too large closed position marking interval and inaccurate closed position indication, when a manual device is used for closing the valve, an operator cannot easily determine whether the valve is closed in place, leakage can occur if the valve is not closed in place, and the valve can be damaged if the valve is excessively closed.
Therefore, a switch indicating device suitable for a lifting rod type valve needs to be designed, accurate indication of the switch position can be achieved, and on-site operators can conveniently identify the position of the valve.
SUMMERY OF THE UTILITY MODEL
The utility model discloses the technical problem that will solve is: in order to overcome the defects of the prior art, the lifting rod type valve switch indicating device is provided.
In order to achieve the above technical effect, the utility model discloses a technical scheme is: the utility model provides a lifting rod formula valve switch indicating device, includes the dust cover, fixes the shield and the valve rod of lift setting in the dust cover at dust cover top, the valve rod top is connected with the pilot rod that runs through the shield, the well lower part and the well upper portion of pilot rod are provided with respectively opens and instructs the scale mark and close and instruct the scale district, just the pilot rod is from closing to instruct the scale district upwards threaded connection in proper order and instruct cover and lock the cap.
Preferably, the dust cover is of a cylindrical structure, and the dust cover are in interference fit and sealing fit.
Preferably, the valve rod is coaxially and threadedly connected with the indicating rod, and the bottom of the indicating rod is provided with a locking nut.
Preferably, the indicator sleeve and the locking cap are both made of a corrosion-resistant metal material.
Compared with the prior art, the beneficial effects of the utility model are that:
1. the accurate indication of the switch position is realized, and the position of the valve can be conveniently identified by field operators;
2. when the valve is worn or leaked, the closing indicating position can be adjusted, and the effectiveness of the closing position is ensured.
The foregoing description is only an overview of the technical solutions of the present invention, and in order to make the technical means of the present invention more clearly understood, the present invention may be implemented according to the content of the description, and in order to make the above and other objects, features, and advantages of the present invention more clearly understood, the present invention will be further described in detail with reference to the accompanying drawings and the embodiments, and it is obvious that the described embodiments are some embodiments, not all embodiments of the present invention.
Drawings
Fig. 1 is a schematic view of the lifting rod type valve switch indicating device of the present invention when it is opened;
fig. 2 is a schematic diagram of the lifting rod type valve switch indicating device of the present invention when closed.
The reference numbers and corresponding designations in the drawings are: 1. the dustproof cover comprises a dustproof cover body, 2, a dustproof cover body, 3, a valve rod, 4, an indication rod, 41, an opening indication scale mark, 42, a closing indication scale mark, 5, an indication sleeve, 6, a locking cap and 7, a locking nut.
Detailed Description
The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic drawings and illustrate the basic structure of the present invention only in a schematic manner, and thus show only the components related to the present invention.
As shown in fig. 1-2, the present embodiment provides a lifting rod type valve switch indicating device, which includes a dust cover 1, a dust cover 2 fixed on the top of the dust cover 1, and a valve rod 3 arranged in the dust cover 1 in a lifting manner, wherein the top of the valve rod 3 is connected with an indicating rod 4 penetrating through the dust cover 2, the middle lower part and the middle upper part of the indicating rod 4 are respectively provided with an opening indicating scale mark 41 and a closing indicating scale area 42, and the indicating rod 4 is upwards connected with an indicating sleeve 5 and a locking cap 6 in turn from the closing indicating scale area 42.
The device keeps an opening indication scale mark 41 and a closing indication scale area 42 on the original indication rod 4, and a thread with a proper specification is processed on the top of the indication rod 4. During assembly: the valve is fully opened (as shown in figure 1), the indicating rod 4 is connected with the valve rod 3, the opening indicating scale mark 41 just exposes out of the top of the dustproof cover 2, then the valve is closed (as shown in figure 2), the indicating rod 4 falls along with the valve rod 3 until the valve is completely closed, the indicating sleeve 5 is mounted to enable the indicating sleeve 5 to be tightly attached to the top of the dustproof cover 2, accurate positioning is completed, and finally the locking cap 6 is screwed up to compress the indicating sleeve 5. It should be noted that, in the actual use process, as the switch of the valve is worn, the closing indication position may slightly change or leak, and at the time, the closing indication position may be adjusted by means of a wrench, a vice or the like.
Compared with the original design, the device realizes the accurate indication of the switch position, is convenient for field operators to identify the valve position, and can adjust the closing indication position when the valve is worn or leaked, thereby ensuring the effectiveness of the closing position.
For carrying out the dismouting change when making things convenient for the trouble, valve rod 3 and the coaxial threaded connection of indicator lever 4, the bottom of indicator lever 4 is provided with lock nut 7, and lock nut 7 is used for fixed indicator lever 4.
The indicating sleeve 5 and the locking cap 6 are both made of corrosion-resistant metal material. In this embodiment, the corrosion-resistant metal material may be selected from iron-based alloy, nickel-based alloy, and the like, so as to ensure that the indicating sleeve 5 and the lock cap 6 can be normally used for a long time after being exposed.
The present invention is not limited to the above specific embodiments, and for those skilled in the art, the above conception can be used without any creative work, and all the changes made fall within the protection scope of the present invention.
