For solving the problems of the technologies described above, the purpose of this utility model is to provide a kind of easy to assembly and valve seat tool for assembling of the valve that assembly quality is higher.
For realizing above-mentioned technical purpose, reach above-mentioned technique effect, the utility model is achieved through the following technical solutions: a kind of valve seat tool for assembling of valve, comprise plug, expansion set, baffle plate, location-plate, action bars and core bar, described core bar and action bars are full thread structure, described plug is bullet, one end of described plug and described core bar is threaded connection, described expansion set is set in outside described core bar, described expansion set is made up of the pullover and loop bar be wholely set, described pullover in be provided with bellmouth, described plug matches with described pullover bellmouth, the other end of described core bar is provided with the first nut, described baffle-plate-sleeve is loaded on outside expansion set, the outer end of the loop bar of described expansion set and the middle part of described location-plate are threaded connection, described location-plate is provided with two action bars relative to the longitudinal center line symmetry of described location-plate by screw thread, each action bars is provided with two the second nuts away from one end of baffle plate.
Further, described baffle plate has positioning boss in the side away from location-plate.
Further, the pullover of described expansion set comprises cylindrical section and conical section, and this pullover conical section is connected with the loop bar one of expansion set.
The beneficial effects of the utility model are: the utility model adopts the plug of bullet to coordinate with the bellmouth of expansion set, by the endoporus swelling of plug by expansion set and valve seat under the effect of the screw-driven between the first nut and core bar, under the effect of the screw-driven then between the second nut and action bars, valve seat is moved, valve seat is in place in valve body.The utility model alleviates the labour intensity of operating personnel, improves the security of operation, also improves the assembling progress of service efficiency and whole product, and ensure that the quality of the valve after assembling; In addition, the utility model structure is simple, and handling ease, materials are few, cost-saving, and simple to operation, easy to maintenance.

Fig. 2 is the structural representation of the expansion set in the utility model.
Fig. 3 be the utility model and valve seat and valve body with the use of time schematic diagram.
Detailed description of the invention
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in detail, to make advantage of the present utility model and feature can be easier to be readily appreciated by one skilled in the art, thus more explicit defining is made to protection domain of the present utility model.
As depicted in figs. 1 and 2, a kind of valve seat tool for assembling of valve, comprise plug 1, expansion set 2, baffle plate 3, location-plate 4, action bars 5 and core bar 6, wherein, core bar 6 and action bars 5 are full thread structure, described plug 1 is bullet, described plug 1 is threaded connection with one end of described core bar 6, expansion set 2 is set in outside core bar 6, and expansion set 2 is made up of be wholely set pullover 21 and loop bar 22, wherein, bellmouth 211 is provided with in pullover 21, described plug 1 matches with the described bellmouth of pullover 21 211, the other end of described core bar 6 is provided with the first nut 61, this first nut 61 is resisted against on the outer face of loop bar 22 of expansion set 2, described baffle plate 3 is set in outside expansion set 2, the outer end of the loop bar 22 of expansion set 2 has screw thread, the outer end of the loop bar 22 of expansion set 2 and the middle part of location-plate 4 are threaded connection, described location-plate 4 is provided with two action bars 5 relative to the longitudinal center line symmetry of described location-plate 4 by screw thread, each action bars 5 is provided with two the second nuts 51 away from one end of baffle plate 3.
Furtherly, described baffle plate 3 has positioning boss 31 in the side away from location-plate 4.During assembling valve seat, this positioning boss 31 is for coordinating with the valve channel of valve body.
Furtherly, pullover 21 of described expansion set 2 is made up of cylindrical section 212 and conical section 213, and this conical section of pullover 21 213 is connected with loop bar 22 one of expansion set 2.
Before assembling valve seat 7, valve seat assembly tooling of the present utility model is assembled.The utility model as shown in Figure 3 and valve seat 7 and valve body 8 with the use of time schematic diagram (only illustrate assemble valve seat in valve body side), first the expansion set 2 of this valve seat assembly tooling is loaded the valve channel of valve body 8, pullover 21 of expansion set 2 are made to extend in the valve seat endoporus of valve seat 7 by valve channel, baffle plate 3 is close on the flange outer face of valve body 8, first nut 61 of core bar 6 end is resisted against on loop bar 22 outer face, then the first nut 61 on turn core bar 6 end, core bar 6 is made to drive plug 1 to move by screw-driven in screwing operations, the conical surface of plug 1 coordinates with the bellmouth 211 of pullover 21, pullover 21 of expansion set 2 are made to swell, thus pullover 21 of expansion set 2 with the valve seat endoporus swelling of valve seat 7.Screw location-plate 4, and turn action bars 5, action bars 5 end is made to be resisted against on baffle plate 3, then two the first nuts 51 on turn action bars 5, make to be resisted against on location-plate 4, further turn first nut 51, makes expansion set 2 and the valve seat 7 together with expansion set 2 swelling move to extreme direction outside flange by screw-driven in the process screwed, is in place by valve seat 7 in valve body 8.The valve seat 7 of valve body 8 opposite side is also assembled according to above method by valve seat assembly tooling of the present utility model.After assembling valve seat 7, valve rod and flashboard are loaded valve body 8.Unscrew the second nut 51 on the first nut 61 of core bar 6 end and action bars 5, the valve seat tool for assembling of this valve can be taken out from valve body 8.
