Abstract
The invention discloses a combined valve body type valve seat structure for a stop valve, and belongs to the technical field of a valve seat assembly. The combined valve body type valve seat structure for the stop valve adopts the following technical scheme that the combined valve body type valve seat structure for the stop valve is characterized by comprising an upper valve body and a lower valve body, wherein a valve flap is arranged in a valve cavity formed by the upper valve body and the lower valve body, and a valve seat ring is formed between flanges formed by the upper valve body and the lower valve body. The combined valve body type valve seat structure achieves the effects that when the valve seat ring is damaged and needs to be replaced, only a flange screw bolt needs to be dismounted, the function can be achieved only through releasing, taking down and replacing the flanges and regulating the position of the valve seat ring, meanwhile, the valve seat ring is extruded between the flanges of the upper valve body and the lower valve body, the valve seat ring can be tightly clamped by using the valve body combining screw bolt force, the structure is simple, and the application range is wide.
Description
Technical field
The present invention relates to a kind of combinaing valve body formula valve seat construction for stop valve, belong 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.
Summary of the invention
The object of this invention 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 present invention 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 present invention 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 invention.
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 invention will be further described.Following examples only for technological scheme of the present invention is clearly described, and can not limit the scope of the invention with this.
As shown in Figure 1 be structural representation of the present invention, the present invention 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 present invention 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 the preferred embodiment of the present invention; it should be pointed out that for those skilled in the art, under the prerequisite not departing from the technology of the present invention principle; can also make some improvement and distortion, these improve and distortion also should be considered as protection scope of the present invention.
