Abstract
The utility model relates to a kind of tap wrench, belongs to petroleum machinery technical field of tools.This tap wrench is made up of claw, slide calliper rule, boosting-rod, and claw is C type, and 3 or 4 slide calliper rule are welded in inside claw or outside, weld boosting-rod in the middle part of claw.Claw and boosting-rod are at same plane, and slide calliper rule are vertically welded on claw, and slide calliper rule welding position is determined according to valve handle support arm.During use, claw can push in valve handle support arm through valve copper cover outside valve handle or by opening, makes slide calliper rule be stuck on the different support arms of valve handle, then grasps rocking arm and rotate, can reach the effect of controlled valve; In operation, owing to having 3 or 4 stressed strong points, effectively prevent, skid, swing and the generation of situation of hurting sb.'s feelings, improve stability and the security of valve operation.
Description
Technical field
The utility model relates to a kind of tap wrench, belongs to petroleum machinery technical field of tools.
Background technology
The industry such as oil, petrochemical industry needs a large amount of manually-operated gates to carry out controlling and operating, free-hand operation is adopted usually to valve handle, but then need to operate by instrument to high pressure valve, usual employing tap wrench is the spanner of two arm of forces, it is by former and later two support arms, as F type spanner or U-shaped spanner, F type spanner, owing to only having two stress points, is easily deviate from during operation, is skidded, swings and cause the event of hurting sb.'s feelings; Patent No. ZL201120272986.X discloses the special Hand-wheel spanner of a kind of high pressure valve and patent No. ZL03229021.7, and to disclose a kind of Hand-wheel spanner be all a kind of U-shaped spanner, be made up of head, middle part and afterbody, also two stress points are only had, this kind of spanner effectively can solve F type spanner and deviate from from handwheel and slippage problems, but can not solve spanner vibration problems.
Summary of the invention
The utility model easily skids to overcome existing tap wrench, swing the defect that the personnel that cause injure, and provides a kind of novel valve spanner.
A kind of tap wrench is made up of claw, slide calliper rule, boosting-rod, and claw is C type, and 3 or 4 slide calliper rule are welded in inside claw or outside, weld boosting-rod in the middle part of claw.
Claw is C type, and middle part is welded on boosting-rod, with boosting-rod at same plane.
Slide calliper rule are vertically welded on claw in the same way, the plane orthogonal that slide calliper rule form with claw and boosting-rod, and slide calliper rule welding position is determined according to valve handle support arm.
Slide calliper rule are set with Anti-slip cover, and hook solid is processed on its top.
Boosting-rod afterbody installs rocking arm, and rocking arm has two limit points, and on the same line, another limit point and slide calliper rule reverse vertical, in boosting-rod, rocking arm are provided with sleeve, sleeve have network decorative pattern for a point and boosting-rod place.
Claw and boosting-rod are at same plane, and slide calliper rule are vertically welded on claw, and slide calliper rule welding position is determined according to valve handle support arm.
The beneficial effects of the utility model are: owing to having 3 or 4 stressed strong points, effectively prevent, skid, swing and the generation of situation of hurting sb.'s feelings, improve stability and the security of valve operation.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Tap wrench of the present utility model, as shown in Figure 1, is made up of claw 1, slide calliper rule 2, boosting-rod 4.Claw 1 is C type, and 3 or 4 slide calliper rule 2 are welded in inside claw 1 or outside, weld boosting-rod 4 in the middle part of claw 1.
Claw 1 and boosting-rod 4 are at same plane, and slide calliper rule 2 are vertically welded on claw 1, and slide calliper rule 2 welding position is determined according to valve handle support arm 7.
Slide calliper rule 2 are set with Anti-slip cover 3, hook solid is processed on its top, prevents skidding from deviating from.
Install Rocker arm 5 at boosting-rod 4 afterbody, Rocker arm 5 is operable to two limit points, and a point and boosting-rod 4 place are on the same line; another limit point and slide calliper rule reverse vertical are in boosting-rod 4; Rocker arm 5 is provided with sleeve 6, sleeve 6 has network decorative pattern, play effect that is laborsaving and protection palm.
During use, claw 1 can push in valve handle support arm through valve copper cover outside valve handle or by opening, makes slide calliper rule 2 be stuck on the different support arms of valve handle, then grasps Rocker arm 5 and rotate, can reach the effect of controlled valve; In operation, owing to having 3 or 4 stressed strong points, effectively prevent, skid, swing and the generation of situation of hurting sb.'s feelings, improve stability and the security of valve operation.
