Abstract
The utility model provides a detaching tool for a back cap of a valve hand wheel. The back cap is composed of an annular back cap body, and multiple concave grooves are evenly formed in the outer side surface of the back cap body. The detaching tool for the back cap of the valve hand wheel is characterized in that the detaching tool is composed of an annular body and a plurality of threaded rods, the number of the threaded rods is equal to the number of the concave grooves, the annular body is provided with threaded holes matched with the threaded rods, the threaded holes are evenly formed in the annular body, a top cube matched with the corresponding concave groove is arranged at the top end, located in the annular body, of each threaded rod, and a tail cube is fixed to the top end, located outside the annular body, of each threaded rod. The detaching tool for the back cap of the valve hand wheel can be matched with back caps of different sizes by changing the positions of the threaded rods in the annular body, can be used for detaching the back caps of different sizes, solves the problem that one back cap of one type needs one detaching tool of the matched size in the past, and is more widely applied.
Description
Technical field
The utility model relates to a kind of valve handwheel lock nut extracting tool, in particular, relates in particular to a kind of valve handwheel lock nut extracting tool that can dismantle the back of the body cap of sizes.
Background technology
In the exploitation of oil gas and transport line, be provided with the handwheel of a greater number.Often need repairing in the daily production Bearning mechanism of main equipment, must frequent dismounting handwheel, the link that the dismounting of handwheel back of the body cap is wasted time and energy often the most.Be all firmly to pound with blunderbuss instrument for back of the body cap, often, after dismounting several times, back of the body cap just can not re-use in the past.
The version of back of the body cap is generally annular, on the medial surface of annular solid, is provided with connecting thread, evenly offers 4 grooves on lateral surface, so that the dismounting of back of the body cap.The patent No. is that CN 201120066259, denomination of invention are the utility model patent file of valve back of the body cap replacer, a kind of back of the body cap replacer is disclosed, it is made up of handle 1, interior six side's steady pins 2, fixing wheel disc 3, removable pin 4, can only dismantle the back of the body cap of a certain fixed dimension, range of application is not extensive.
Summary of the invention
The utility model, in order to overcome the shortcoming of above-mentioned technical problem, provides a kind of valve handwheel lock nut extracting tool that can dismantle the back of the body cap of sizes.
Valve handwheel lock nut extracting tool of the present utility model, back of the body cap is made up of annular back of the body cap body, on the medial surface of back of the body cap body, is provided with internal thread, on the lateral surface of back of the body cap body, evenly offers multiple grooves; Its special feature is: described extracting tool is made up of annular solid and the multiple threaded rods that are arranged on annular solid, and the internal diameter of annular solid is greater than the external diameter of back of the body cap body, and the quantity of threaded rod equates with the quantity of groove; On annular solid, offer the screwed hole matching with threaded rod, screwed hole evenly arranges on annular solid, the top of the threaded rod in annular solid is provided with the top square matching with groove, and the top of the threaded rod outside annular solid is fixed with afterbody square.
Valve handwheel lock nut extracting tool of the present utility model, comprises the long handle that adds that orders about annular solid rotation, and the one end that adds long handle offers the cavity coordinating with afterbody square.
Valve handwheel lock nut extracting tool of the present utility model, the number of the threaded rod on number and the annular solid of described back of the body cap body upper groove is 4.
The beneficial effects of the utility model are: valve handwheel lock nut extracting tool of the present utility model, by the threaded rod equating with groove number is set on annular solid, on annular solid, offer the screwed hole matching with threaded rod, the top of threaded rod arranges the top square with groove fit, by changing the position of threaded rod in annular solid, realize the coordinating of back of the body cap of extracting tool of the present utility model and different size, can dismantle the back of the body cap of different size, solve the problem that the back of the body cap of a model needs the extracting tool of a size to be mated in the past, the application that makes to carry on the back cap extracting tool is more extensive.
By the long handle that adds that can be connected with the afterbody square on threaded rod is set, the arm of force of extracting tool is lengthened, instrument of the present utility model is used more time saving and energy saving.
Accompanying drawing explanation
Fig. 1 is the structural representation of valve handwheel lock nut;
Fig. 2 is the structural representation of valve handwheel lock nut extracting tool of the present utility model;
Fig. 3 is the use state diagram of valve handwheel lock nut extracting tool of the present utility model.
In figure: 1 back of the body cap body, 2 grooves, 3 internal threads, 4 annular solids, 5 threaded rods, 6 screwed holes, 7 top squares, 8 afterbody squares, 9 add long handle.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment, the utility model is described in further detail.
As shown in Figure 1, provided the structural representation of existing valve handwheel lock nut, it is formed by annular back of the body cap body 1, on the inner surface of back of the body cap body 1, is internal thread 3, and the threaded engagement on internal thread 3 and valve shaft, realizes fixing handwheel.On the lateral surface of back of the body cap body 1, evenly offer groove 2, so that the dismounting of back of the body cap; Existing back of the body cap method for dismounting, is firmly to pound after blunderbuss is placed in to groove 2, and after entering dismounting several times, groove 2 will be polished, and makes the dismounting of carrying on the back cap become very difficult.
As shown in Figure 2, provided the structural representation of existing valve handwheel lock nut extracting tool, it comprises annular solid 4, threaded rod 5, top square 7, afterbody square 8; The internal diameter of annular solid 4 is greater than the external diameter of back of the body cap body 1, and threaded rod 5 evenly arranges on annular solid 4, offers the screwed hole 6 matching with threaded rod 5 on annular solid 4.The top that is positioned at the threaded rod 5 of annular solid 4 is fixed with top square 7, and afterbody square 8 is fixed on the top of the threaded rod 5 that is positioned at annular solid 4 outsides.Top square 7 matches with the groove 2 on back of the body cap body 1.Moment when increasing dismounting back of the body cap, also can arrange and add long handle 9, adds and on long handle 9, offers the cavity matching with afterbody square 8.Conventionally often under, groove 2 numbers on back of the body cap body 1 are 4, and correspondingly, the number of the threaded rod 5 arranging on annular solid 4 also should be 4.
As shown in Figure 3, provide the use state diagram of valve handwheel lock nut extracting tool of the present utility model, in the process using, by rotation threaded rod 5, the afterbody square 8 on its top is moved to and can be embedded in the position in annular solid 4 upper grooves 2, all top squares 7 are stretched in groove 2, fix with the afterbody square 8 on threaded rod 5 adding long handle 9, by exerting pressure to adding long handle 9, back of the body cap can be disassembled like a cork.
Valve handwheel lock nut extracting tool of the present utility model, realize the coordinating of back of the body cap of extracting tool of the present utility model and different size, can dismantle the back of the body cap of different size, solved the problem that the back of the body cap of a model needs the extracting tool of a size to be mated in the past, the application that makes to carry on the back cap extracting tool is more extensive.
