Description
Technical field
The utility model is related to a kind of valve auxiliary switch tools, can use the various petrochemical industries of auxiliary switch and other industries
The annular hand of the various valves used belongs to valve opening technical field of tools.
Background technology
In Petroleum Production, it can use and arrive various valves, most of valves are electronic keying, and minority is by manually opening
It closes.Rescue and relief work etc. is occurring in emergency circumstances, electronic keying is all failed, and needs to realize opening for valve by manual rotation's handwheel
It closes, fully opening or closing for certain valves needs operator to rotate handwheel hundreds and thousands of times, and workload is very big.Due to valve
Compare the medium and environment flowed through in the bigger either valve rod leading screw corrosion of accurate or filler pretightning force or valve
Bigger etc. the situation of the temperature difference can all cause the keying of valve difficult.
Rescue and relief work etc. is occurring in emergency circumstances, valve periphery is all greasy dirt, and people is difficult completely close valve, and at any time
There is the risk that fire occurs, too close to the dangerous height of valve and is not easy to withdraw.The initial stage of valve " unlatching " and " closing "
Latter stage needs enlarging moment, is manually difficult to disk and starts to take turns.In practical work, the rotation of valve handle is generally required by means of F shapes
Spanner and its derived product have feature simple in structure, easy to use.The front end of F-shaped wrench is set there are two perpendicular to handle
Short column, two short columns be mutually parallel and mutually across a certain distance, the spacing is suitable with the diameter of handwheel cross section.In use, by F shapes
Two short columns of spanner are stuck in the inner side and outer side of handle circumference, and handle is in handwheel circumference in same plane, and arm is drawn
The tail portion of fixed handle is by hand wheel rotating, therefore the size of F-shaped wrench will match with appearance with corresponding valve.
Since the arm of force is short, the direction of power is less than best angle, and arduously, especially female employee is inconvenient for use.For size phase
To larger, installation site is not satisfactory, the larger valve of disk dynamic resistance, or in emergency circumstances needs quick closedown or unlatching
Valve, F-shaped wrench are then difficult to play ideal effect.
It is two-point contact since two short columns of F-shaped wrench front end are contacted with handwheel, contacts defective tightness, wheel rim is clamped
Loosely, if applying larger power on handle, F-shaped wrench is easy to slip from handwheel, it is contemplated that may when metal friction, shock
Pyrophoric influence is produced, is easy to bring security risk；Human body is possibly even hit when slippage, is caused the accident.
Utility model content
The purpose of this utility model is that overcoming problems of the prior art, a kind of valve auxiliary switch work is provided
Tool, convenient for in-site installation on valve, do not influence the normal use of valve, can fast opening/closing valve, can be carried while laborsaving
The safety of height operation.
In order to solve the above technical problems, a kind of valve auxiliary switch tool of the utility model, including central rotating body and
Extension bar, the extension bar are symmetrically plugged on the central rotating body, and the central rotating body includes central cylinder, described
The center of central cylinder be equipped with for valve rod by stem through-hole, be arranged with along diameter on the circumference of the central cylinder
To outwardly directed dog, the external end head of each dog is respectively equipped with radially inwardly extending extension bar socket joint slot, each institute
The inner termination for stating extension bar is plugged on respectively in corresponding extension bar socket joint slot, and the root of each extension bar is hung with hand respectively
Jockey is taken turns, the top of each handwheel jockey is suspended on corresponding reinforcing by horizontal-extending extension bar slot respectively
On bar, the lower part of each handwheel jockey is respectively equipped with C-shaped jaw of the opening towards central rotating body axis, each C-shaped pincers
Mouth is stuck on the circumference of valve handle and is fixedly connected with valve handle by jaw trip bolt.
Compared with the existing technology, the utility model achieves following advantageous effect：When installation, the nut on valve rod is laid down,
Central cylinder is pressed in the top of valve handle, valve rod is pierced by from the stem through-hole of central cylinder；Extension bar is distinguished
It is plugged in the extension bar socket joint slot of each dog, is set in handwheel jockey on extension bar simultaneously by extension bar slot
It is advanced at handwheel circumference, tightening jaw trip bolt makes handwheel jockey be fixedly connected with the hand wheel respectively.Due to extension bar
Length be much larger than the radius of valve handle, it is very laborsaving by extension bar rotating valve handwheel, and can continuous rotation；Occur tight
When anxious situation, without finding handle, also need not often rotate i.e. replace spanner clamping position, can fast opening/closing valve,
Will not slip and cause personal injury, and will not because collision generate spark caused by explosion-proof accident.
Jaw insert of the pad below valve handle is equipped with as the improvement of the utility model, in the C-shaped jaw, it is described
Jaw trip bolt is screwed on the lower face of the handwheel jockey, and the upper end of the jaw trip bolt is resisted against institute
State the lower section of jaw insert.The coupling mechanism force that jaw insert can increase C-shaped jaw to valve handle is set, jaw trip bolt is convenient for
