Abstract
The utility model relates to a hand tool, in particular to a pair of special pipe pliers for a gland of a lathe dog valve, which comprises a fixed jaw, a movable jaw, a handle body, a positioning nut and a guiding groove. The special pipe pliers for the gland of the lathe dog valve are characterized in that the lower part of the fixed jaw is provided with external threads which are matched and connected with internal threads of the handle body; the guiding groove with large bottom and small mouth is arranged in the axial direction; and the positioning nut is arranged on the movable jaw and axially moves inside the guiding groove. The special pipe pliers for the gland of the lathe dog valve have the advantages that the special pipe pliers not only have the function of supporting but also can adjust the length of the handle body to increase the moment arm because the fixed jaw can be rotated and moved inside the handle body; and a head of the pipe pliers after modification is thinner than the head of the prior pipe pliers, the phenomenon that a valve body is nibbled or the gland can not be clamped can not occur when the gland is fastened, thereby the special pipe pliers for the gland of the lathe dog valve not only are convenient to operate but also shorten the maintenance time.
Description
One, technical field
The utility model relates to a kind of hand-operated tools, particularly relates to a kind of clip valve gland special tube pliers.
Two, background technology
High pressure clamping hoop type gate is in long-term the use, and gland is subjected to the external force effect easily to thread off, become flexible, and the high pressure water, oil, gas takes place reveal, and causes the production management difficulty, more exists bigger potential safety hazard.Existing pipe wrench head is thicker, the card not upper press cover or the phenomenon of stinging valve often occur, neither smoothly, has prolonged the operating maintenance time again in the use.
Three, utility model content
The purpose of this utility model is exactly the defective that exists at prior art, and clip valve gland special tube pliers a kind of simple in structure, easy to use is provided.
The purpose of this utility model is achieved by the following technical solution, it is made up of regular jaw, moving jaw, handle body, setscrew nut and gathering sill, external screw thread is arranged at the bottom that it is characterized in that regular jaw, be connected with the internal thread coupling of handle body, the big young gathering sill in the end is axially arranged, setscrew nut is arranged on the moving jaw, in gathering sill, axially move.
The beneficial effects of the utility model are, movingly can play certain supporting role because regular jaw can shift in the handle body inward turning, and can adjust handle body length again increases the arm of force.When fastening gland, can not occur again stinging valve body or blocking the not phenomenon of upper press cover, both easy to operate, shortened maintenance time again.
Four, description of drawings
Accompanying drawing is a structural representation of the present utility model.
1-regular jaw; 2-moving jaw; 3-setscrew nut; 4-handle body; 5-gathering sill.
Five, the specific embodiment
With reference to accompanying drawing, it is made up of regular jaw 1, moving jaw 2, handle body 4, setscrew nut 3 and gathering sill 5, external screw thread is arranged at the bottom that it is characterized in that regular jaw 1, be connected with the internal thread coupling of handle body 4, the big young gathering sill 5 in the end is axially arranged, setscrew nut 3 is arranged on the moving jaw 2, can in gathering sill 5, axially move.During use, at first adjust handle body 4, unclamp setscrew nut 3 to suitable length, adjust moving jaw 2, the opening that makes clip valve gland special tube pliers is stung two grooves that press on the cap to correct position with regular jaw 1 and moving jaw 2, screwed in place nut 3 steadily firmly gets final product.Because handle body can freely stretch within the specific limits, can play support, fixation, can increase the arm of force again.Utilize the adjusting nut on the existing pipe wrench of setscrew nut 3 replacements on the moving jaw, make head of the present utility model thinner, use convenient.
