Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is elaborated.Should be understood that, embodiment described herein only, for description and interpretation the utility model, is not limited to the utility model.
In the utility model, in the situation that not doing contrary explanation, the noun of locality of use typically refers to reference to upper and lower, left and right shown in the drawings as " upper and lower, left and right "; " inside and outside " refers to inside and outside with respect to the profile of each parts itself.
The utility model provides a kind of pipe plug, and this pipe plug comprises the main part 21 in the end 11 of pipe for shutoff, is provided for this pipe plug to apply external force with the lug boss 23 of this pipe plug of installation or removal on main part 21.Therefore, than the situation of utilizing the longitudinal lines on pipe plug outer circumferential face to provide force bearing point to operate in prior art, this lug boss 23 can be for force bearing point more reliably, thereby the operation of being convenient to installation personnel is to increase work efficiency.
Lug boss 23 is various shapes, as long as it can be used in pipe plug is applied to external force.This lug boss 23 can either form the identical shape in cross section, also can form the different shape in cross section.This cross section can be rectangle, triangle, pentagon etc.
Particularly, as shown in Figure 1, in the first side of main part 21, be provided with tubular thread auxiliary section 22, on this tubular thread auxiliary section 22, be formed with for forming with pipe outside thread or the internal thread being threaded, the part that is positioned at tubular thread auxiliary section 22 of the first side surface forms for covering the shutoff face on end 11, and lug boss 23 is arranged on second side surface relative with the first side of main part 21.Pipe plug is threaded connection in pipe, thereby and the lug boss 23 being arranged on the second side surface can easily be controlled and be conducive to increase work efficiency by operator.
Pipe plug described in the utility model is applied in when comprising tube body 10 and being set in the tubular construction of the female pipe joint 12 of tool on tube body 10, on tubular thread auxiliary section 22, be formed with the outside thread for being threaded with pipe joint 12, pipe plug also comprises and being arranged on main part 10 for covering the backstop extension 27 on the end face 13 of described pipe joint 12.Like this, backstop extension 27 can coordinate tubular thread auxiliary section 22 to form labyrinth seal (tortuous sealing), thereby guarantee the reliable sealing between shutoff face and the hydraulic pressure mouth of pipe, impurity and dust etc. cannot be entered in hydraulic tube from screw thread ingress, thereby guarantee reliably the turbidity test of hydraulic system.
Preferably, the inner peripheral surface of tubular thread auxiliary section 22 and shutoff face form column holding space with containing pipe.As shown in Figure 1, described inner peripheral surface can form the circumferential surface of easy processing, thereby makes the simple shape of tubular thread auxiliary section 22, easily processing.Preferably, make to be formed with gap between the inner peripheral surface of tubular thread auxiliary section 22 and the outer circumferential face of tube body 10, thereby operator are aligned when carrying out inner peripheral surface and outer circumferential face arduously, reduced operation easier, thereby be conducive to increase work efficiency further.
The pipe that the shape of shutoff face and backstop extension 27 all can will be used in conjunction with according to this pipe plug designs.As a kind of embodiment of the present utility model, the stop surface that shutoff face contacts than the end face 13 for pipe joint 12 of backstop extension 27 tubular thread auxiliary section 22 axially on more away from lug boss 23.Like this, not only can strengthen by the dislocation of shutoff face and stop surface the effect of labyrinth seal, and can leave enough materials at lug boss 23 and main part 21 contacting points, to guarantee the intensity of lug boss 23.
Preferably, the top of lug boss 23 forms cambered surface 25, thereby can prevent the injury to operator of sharp-pointed place on lug boss 23.Preferably, lug boss 23 is connected to the upper surface of main part 21 by arc surface 26.Like this, not only can expand the connection area of lug boss 23 and main part 21, thereby guarantee further the intensity of lug boss 23, can also increase the area of controlling operating for operator on lug boss 23.
When pipe plug described in the utility model is applied in and is provided with externally threaded tubular construction on outer circumferential face, on tubular thread auxiliary section 22, be formed with for forming with pipe the internal thread being threaded.
As of the present utility model preferred embodiment a kind of, on lug boss 23, offer porose 24.Like this, utilize the end of tool wrench etc. can be easily inserted in hole 24, thereby can easily realize reliably rotary manipulation.Even when being threaded inefficacy, also can utilize the hole 24 on above-mentioned lug boss 23 to impose on the power of pipe plug to make progress, this pipe plug is extracted from pipe, can not make operator process the time a large amount of because the inefficacy being threaded spends, thereby can improve further operator's working efficiency.
Below describe by reference to the accompanying drawings preferred implementation of the present utility model in detail; but; the utility model is not limited to the detail in above-mentioned mode of execution; within the scope of technical conceive of the present utility model; can carry out multiple simple variant to the technical solution of the utility model, these simple variant all belong to protection domain of the present utility model.
It should be noted that in addition, each concrete technical characteristics described in above-mentioned embodiment, in reconcilable situation, can combine by any suitable mode, for fear of unnecessary repetition, the utility model is to the explanation no longer separately of various possible compound modes.
In addition, between various mode of execution of the present utility model, also can carry out combination in any, as long as it is without prejudice to thought of the present utility model, it should be considered as content disclosed in the utility model equally.
