Background technology
When assembling valve products such as gate valves, the assembling of valve seat is the key of valve assembling, and the quality of valve seat assembling directly has influence on the sealing property of valve and service life etc.Valve seat is provided with sealing ring, and needs to accomplish interference fit between the valve seat installing hole of valve seat and valve body, therefore the assembly difficulty of valve seat is larger.The assembly tool of current valve seat not only assembles inconvenience, also cannot be in place by valve seat as requested simultaneously, and easily damages the sealing ring on valve seat.And valve seat is installed not in place, also make the installation of valve rod and flashboard increase difficulty, thus the whole efficiency of assembling of valve reduced, the valve seal performance after assembling and serviceability poor, also affect the service life of valve.
Summary of the invention
For solving the problems of the technologies described above, the object of the present invention 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 present invention 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 invention has the beneficial effects as follows: the present invention 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.Present invention alleviates the labour intensity of operating personnel, improve the security of operation, also improve the assembling progress of service efficiency and whole product, and ensure that the quality of the valve after assembling; In addition, structure of the present invention 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 present invention.
Fig. 3 be the present invention 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 invention is described in detail, can be easier to make advantages and features of the invention be readily appreciated by one skilled in the art, thus more explicit defining is made to protection scope of the present invention.
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.
