Abstract
The utility model discloses a kind of combinaing valve body formula valve seat construction for stop valve, belong to valve component technical field.The utility model adopts following technological scheme: a kind of combinaing valve body formula valve seat construction for stop valve, it is characterized in that, comprise upper valve body, lower valve body, be provided with flap in the valve pocket that described upper valve body and lower valve body are formed, between the flange that described upper valve body and described lower valve body form, be provided with seat ring.The utility model achieves when seat ring damage needs to change, only flange bolt need be dismantled, unclamp flange take off and change, the function of regulating valve seat ring position, seat ring is squeezed between upper valve body and lower valve flange simultaneously, the bolt force utilizing valve body to combine just can pinched valve seat ring, structure is simple, applied widely.
Description
Technical field
The utility model relates to a kind of combinaing valve body formula valve seat construction for stop valve, belongs to valve component technical field.
Background technique
Stop valve is in industrialized continuous flow procedure, due to seat of stop valve assembly change by the temperature variation of flowing medium, pressure, wash away, wear and tear, particulate matter accumulates and extrudes and corrode and cause valve component spot corrosion, defect, impression and depression, and then produce the poorly sealed interior leakage problem of junction plane, become one of reason affecting stop valve working life.
Model utility content
The purpose of this utility model is to provide a kind of combinaing valve body formula valve seat construction for stop valve, facilitate seat of stop valve ring from valve body dismounting and install, in solution prior art when more serious defect appears in sealing surface of seat, the technical problem of whole deck valve door can only be scrapped because maintenance cost is high.
The utility model adopts following technological scheme: a kind of combinaing valve body formula valve seat construction for stop valve, it is characterized in that, comprise upper valve body, lower valve body, be provided with flap in the valve pocket that described upper valve body and lower valve body are formed, between the flange that described upper valve body and described lower valve body form, be provided with seat ring.
Preferably, the lower surface of described seat ring contacts with described lower valve body.
Preferably, described Flange joint is with bolts.
Preferably, the thickness being vertically highly greater than described upper valve body of described seat ring.
Preferably, described seat ring is stepped, is convenient to the bolt force pinched valve seat ring of valve body combination.
Preferably, described seat ring and described flap configure in pairs, and described seat ring is coaxial with described flap.
The beneficial effect that the utility model reaches: (1) when seat ring damages need to change time, only need dismantle flange bolt, unclamp flange take off and change, regulating valve seat ring position; (2) seat ring is squeezed between upper valve body and lower valve flange, and the bolt force utilizing valve body to combine can pinched valve seat ring.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
The implication marked in figure: valve body under 1-, 2-upper valve body, 3-flap, 4-seat ring.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further described.Following examples only for clearly the technical solution of the utility model being described, and can not limit protection domain of the present utility model with this.
As shown in Figure 1 be structural representation of the present utility model, the utility model proposes a kind of combinaing valve body formula valve seat construction for stop valve, it is characterized in that, comprise upper valve body 2, lower valve body 1, be provided with flap 3 in the valve pocket that upper valve body 2 and lower valve body 1 are formed, between the flange that upper valve body 2 and lower valve body 1 form, be provided with seat ring 4.
The lower surface of seat ring 4 contacts with lower valve body 1; Flange joint is with bolts; The thickness being vertically highly greater than upper valve body 2 of seat ring 4; Seat ring 4 is stepped, is convenient to the bolt force pinched valve seat ring 4 of valve body combination; Seat ring 4 and flap 3 configure in pairs, and seat ring 4 is coaxial with flap 3.
The beneficial effect that the utility model reaches: (1) when seat ring damages need to change time, only need dismantle flange bolt, unclamp flange take off and change, regulating valve seat ring position; (2) seat ring is squeezed between upper valve body and lower valve flange, and the bolt force utilizing valve body to combine can pinched valve seat ring.
The above is only preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the prerequisite not departing from the utility model know-why; can also make some improvement and distortion, these improve and distortion also should be considered as protection domain of the present utility model.
