The advantages are that: utilize the utility model discloses an in two latches and housing screw inserted the three draw-in groove that corresponds with the stopping nut, when rotating through operating handle drive dop, promote the inner wall that corresponds the draw-in groove along the rotation direction by two latches and housing screw, and then pull the stopping nut rotation, realize the fastening to the stopping nut, and then realize the quick adjustment to the stopping nut, the utility model discloses simple structure, convenient operation.
Description
The technical field is as follows:
the utility model relates to a sodium valve maintenance technical field, in particular to instrument for adjusting sodium valve stopping nut are used in production of metal sodium.
The background art comprises the following steps:
in the sodium metal production process, the sodium valve that uses appears easily for a long time running and is used for compressing tightly the stopping nut of valve body internal seal filler and appearing not hard up the phenomenon, if can not in time screw up, can appear valve rod department because of sealing the phenomenon that leads to the sodium metal seepage, the liquid sodium metal seepage back of high temperature is very easily caught fire and is ignited near combustible substance, simultaneously, in case can appear exploding with the water contact. Therefore, in the routine maintenance process, if the check nut of the metal sodium valve is loosened or leakage is found, the check nut of the valve body needs to be adjusted and screwed in time to compress the sealing filler in the sodium valve. At present, the retaining nut is adjusted and fastened by using snap spring pliers, but if the phenomenon that metal sodium leaks into threads of the retaining nut exists, the retaining nut is difficult to fasten due to blocking, the snap spring pliers are damaged or even deformed, and the normal maintenance efficiency is influenced; the adjustment of the sodium valve retaining nut is realized by using a metal chisel and an iron hammer, and the sodium valve retaining nut has the defects of low fastening efficiency, time and labor waste and damage to a groove of the retaining nut.
The utility model has the following contents:
an object of the utility model is to provide a simple structure, be convenient for fasten the adjustment sodium valve stopping nut instrument for nut in order to improve maintenance efficiency of stopping nut.
The utility model discloses implement by following technical scheme: a tool for adjusting a sodium valve retaining nut comprises a handle and a chuck with an opening; two opposite clamping teeth are fixed at two ends of an opening of the clamping head, and the handle is fixed on the outer wall of the clamping head; the chuck is provided with a compression screw which is arranged between the two clamping teeth in a penetrating and screwed manner, and the compression screw has the same distance with the two clamping teeth along the circumferential direction of the opening of the chuck.
Further, the chuck is of a semicircular structure.
The utility model has the advantages that: utilize the utility model discloses an in two latches and housing screw inserted the three draw-in groove that corresponds with the stopping nut, when rotating through operating handle drive dop, promote the inner wall that corresponds the draw-in groove along the rotation direction by two latches and housing screw, and then pull the stopping nut rotation, realize the fastening to the stopping nut, and then realize the quick adjustment to the stopping nut, the utility model discloses simple structure, convenient operation.
Description of the drawings:
fig. 1 is a schematic structural diagram of the present invention.
Fig. 2 is a schematic view of a first usage state of the present invention.
Fig. 3 is a schematic view of a second usage state of the present invention.
Fig. 4 is a third schematic view of the usage state of the present invention.
The parts in the drawings are numbered as follows: handle 1, dop 2, latch 3, housing screw 4, stopping nut 5.
The specific implementation mode is as follows:
the technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
As shown in fig. 1, the utility model provides a tool for adjusting a sodium valve retaining nut, which comprises a handle 1 and a chuck 2 with an opening; the clamping head 2 is of a semicircular structure, and two clamping teeth 3 which are oppositely arranged are fixed on the inner walls of two ends of the opening of the clamping head 2; in the embodiment, the locking device is used for adjusting the retaining nut 5 provided with 4 clamping grooves, and the two clamping teeth 3 are used for being clamped in the two clamping grooves opposite to the retaining nut 5; the chuck 2 is provided with a compression screw 4 which is arranged between the two latch teeth 3 in a threaded connection manner, the end part of the compression screw 4 is movably arranged in the opening of the chuck 2, the distance between the compression screw 4 and the two latch teeth 3 along the circumferential direction of the opening of the chuck 2 is equal, the compression screw 4 corresponds to the third clamping groove of the retaining nut 5, namely, the end part of the compression screw 4 is inserted into the clamping groove of the retaining nut 5 which is arranged between the two latch teeth 3 by rotating the compression screw 4 according to the actual use requirement, so that the bearing capacity of the utility model is improved, and a handle 1 is fixed on the outer wall of the chuck 2; utilize the utility model discloses an in two latches 3 and housing screw 4 insert the three draw-in groove that corresponds with stopping nut 5, when rotating through 1 drive dop 2 of operating handle, it is rotatory to pull stopping nut 5 by two latches 3 and housing screw 4, can fasten stopping nut 5, and then realize the quick adjustment to stopping nut 5.
Instructions for use: as shown in fig. 2, firstly, the handle 1 is manually gripped, the chuck 2 is sleeved on the retaining nut 5, one of the latch teeth 3 extends into one of the slots of the retaining nut 5 and extends into the bottom of the slot, and at the moment, the other latch tooth 3 is arranged at the slot opening of the corresponding slot; as shown in fig. 3, the chuck 2 is moved along the connecting line direction of the two latches 3, so that the other latch 3 is placed in the corresponding slot, at this time, the two latches 3 are both placed in the two opposite slots, and the compression screw 4 is opposite to the third slot of the retaining nut 5, and the compression screw 4 is rotated to make the end portion of the compression screw extend into the slot; as shown in fig. 4, the operating handle 1 drives the chuck 2 to rotate, the two latch teeth 3 and the compression screw 4 push the inner wall of the corresponding clamping groove along the rotation direction, and then the retaining nut 5 is pulled to rotate, so that the retaining nut 5 is fastened.
The above description is only a preferred embodiment of the present invention, and should not be taken as limiting the invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
