Abstract
The dismounting device is suitable for the valve rod. Use instruments such as sledgehammer to strike vibrations and slowly extract a door pole with it at the pole in-process of taking out a door, the door pole takes place deformation to a certain extent, and crooked even finally leads to a door pole to scrap. The utility model discloses the constitution includes: the valve comprises a valve door seat (1), a valve door rod (5) and a valve door core (4), wherein a positioning block (3) is connected to the valve door rod in a threaded manner, two ends of the positioning block are in sliding fit with a tension screw rod (2), and the tension screw rod is connected to the valve door seat in a threaded manner; each tension screw rod is in threaded connection with an adjusting nut (6). The utility model is used for the dismantlement of valve door pole.
Description
Technical Field
The utility model relates to a dismounting device suitable for valve door-lever.
Background
The valve is a parameter pipeline accessory used for opening and closing a pipeline, controlling the flow direction, adjusting and controlling the conveying medium, and is applied to places needing to convey the medium, such as power stations, water stations, gas stations and the like. The valve needs to control the flow at regular time or in irregular time in the using process, and various problems, such as leakage of the granny, jamming of the valve, falling of a copper sleeve and the like, can be encountered in frequent or long-term use, so that the normal use of a pipeline system is directly influenced, and the harmfulness of equipment is self-evident. The heat energy conveying system mainly depends on the pipeline and the valve to carry out heat energy conveying and control, and most of the pipelines and the valve are applied to the high-temperature and high-pressure environment, so that the requirements on the valve and the pipelines are higher, the valve needs to be periodically overhauled and maintained, the problems are timely solved, and the normal operation of the system is ensured. In the use process of the valve, defects occur in the use process due to the problems that a non-standard process is frequently operated, or the pressure inside a pipeline is greatly changed and the like. Generally, valves are disassembled for maintenance in order to save cost and understand the internal construction of the valve in detail. In the disassembly process, after all parts of the valve are disassembled, the valve is disassembled. However, in the operation and use process of the valve, especially under the action of high pressure of a system pipeline, in order to ensure that each part of the valve is not leaked, the tightening force of each part is tightened to the maximum, and the huge pressure of the system per se enables each part of the valve to generate higher sealing tightening force, so that the valve opening and closing acting force is increased under the long-term action, the opening and closing difficulty is improved, and the valve is particularly disassembled in the last step: it is most difficult to pull out the door lever. The door rod is a smooth round rod except for the control and connection actuating mechanism which is in threaded connection. If the door rod is slowly pulled out by knocking and vibrating the door rod by using tools such as a sledge hammer and the like in the door rod pulling process, the door rod is deformed or even bent to a certain degree, and finally the door rod is scrapped; if the door rod is pulled out by using tools such as a steel wire rope forcibly, potential safety hazards to workers and equipment exist, the door rod is inevitably damaged, and the effect is poor. The working efficiency is greatly reduced.
Disclosure of Invention
The utility model aims at providing a dismounting device suitable for valve door pole.
The above purpose is realized by the following technical scheme:
a dismounting device suitable for a valve door rod comprises a valve door seat, the valve door rod and a valve door core, wherein a positioning block is connected to the valve door rod in a threaded manner, two ends of the positioning block are in sliding fit with a tension screw rod, and the tension screw rod is connected to the valve door seat in a threaded manner;
and each tension screw rod is in threaded connection with an adjusting nut.
The dismounting device is suitable for the valve rod, and the adjusting nut is propped against the positioning block.
Has the advantages that:
1. the utility model discloses locating piece and valve door pole threaded connection set up two pulling force lead screws simultaneously and remove spacingly as the locating piece, can be so that the even atress in both sides, slowly extract the door pole from the gate seat.
2. The utility model discloses overhaul valve efficiency has been improved greatly. Meanwhile, the valve rod of the valve is effectively protected from being damaged by external factors.
Description of the drawings:
FIG. 1 is a schematic structural diagram of the present invention;
FIG. 2 is a schematic view of the positioning block;
in the figure: 1. a valve seat; 2. a tension screw rod; 3. positioning blocks; 4. a valve core; 5. a valve stem; 6. adjusting the nut; 7. a central bore; 8. and a through hole.
The specific implementation mode is as follows:
example 1:
a dismounting device suitable for a valve door rod comprises a valve door seat 1, a valve door rod 5 and a valve door core 4, wherein a positioning block 3 is connected to the valve door rod in a threaded manner, two ends of the positioning block are in sliding fit with a tension screw rod 2, and the tension screw rod is connected to the valve door seat in a threaded manner;
each tension screw rod is connected with an adjusting nut 6 through threads.
Example 2:
according to the dismounting device for the valve rod of the valve in the embodiment 1, the adjusting nut is abutted against the positioning block.
The working principle is as follows: firstly, a positioning block is in threaded connection with a valve door rod, the positions of the positioning block and the valve door rod are adjusted to enable through holes 8 on two sides to be opposite to threaded holes on a valve door seat, then a tension screw rod penetrates through the positioning block and is in threaded connection with an adjusting nut, the tension screw rod is in threaded connection with the valve door seat, the adjusting nut is rotated to be abutted against the positioning block, when the valve is installed in a horizontal mode, the tension screw rod can be hung on two sides of the positioning block through inverted chain crossed hooks, force is slowly applied, the valve rod is slowly pulled out of the valve seat, and the valve rod is recommended to slowly shake left and right in the pulling-out process, so that unsafe consequences caused by the fact that the valve rod is pulled out instantly;
the valve is vertically installed, two jacks are used on the surface of a valve seat, force is slowly applied, the jacks are jacked on the positioning block to jack up the positioning block, the positioning block needs to shake left and right in the same way, and unsafe consequences are avoided;
the adjusting nuts of each tension screw rod can be simultaneously rotated without tools, so that the two adjusting nuts can simultaneously push against the positioning block to move, and the valve rod can be pulled out.
