Abstract
The utility model discloses a spring roof pressure formula disk seat for stop valve belongs to seat kits technical field. The utility model discloses a spring roof pressure formula disk seat for stop valve, its characterized in that includes valve cup ring, spring unit, open flutedly on the disk seat, the valve cup ring passes through spring unit is fixed set up in in the recess of disk seat. The utility model discloses a when the valve cup ring damage the back only need change in pairs seat kits can the function, while valve cup ring and valve clack can be joined in marriage in pairs and is ground, can ensure the pretightning force of spring according to the pressure rating.
Description
Technical field
The utility model relates to a kind of spring top pressure type valve seat for stop valve, belongs to valve component technical field.
Background technique
Stop valve is along with using improving constantly of material behavior, and structure is updated, and its working life is also constantly extended.But 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 spring top pressure type valve seat for stop valve, facilitate seat of stop valve 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 spring top pressure type valve seat for stop valve, it is characterized in that, comprise seat ring, spring assembly, described valve seat has groove, described seat ring is fixedly installed in the groove of described valve seat by described spring assembly.
Preferably, spring assembly comprises upper spring circle, lower spring circle, spring.
Preferably, seat ring comprises outer ring, inner ring, and the spring force top that utilizes above of outer ring is consolidated, is squeezed on valve body.
Preferably, the outer ring of seat ring, inner ring and bottom surface are all positioned in the groove of valve seat.
Preferably, seat ring and flap configure in pairs.
Preferably, the radial dimension of seat ring is more than or equal to the radial dimension of flap.
The beneficial effect that the utility model reaches: only need after (1) seat ring damages to change valve component in pairs; (2) seat ring and the paired facing-up of flap, can ensure the pretightening force of spring according to pressure rating.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is detonation configuration schematic diagram of the present utility model.
The implication marked in figure: 1-upper spring circle, 2-spring, 3-lower spring circle, 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 spring top pressure type valve seat for stop valve, it is characterized in that, comprise seat ring 4, spring assembly, valve seat has groove, and seat ring 4 is fixedly installed in the groove of valve seat by described spring assembly.
Fig. 2 is detonation configuration schematic diagram of the present utility model, and spring assembly comprises upper spring circle 1, lower spring circle 3, spring 2; Seat ring 4 comprises outer ring, inner ring, and the spring force top that utilizes above of outer ring is consolidated, is squeezed on valve body; The outer ring of seat ring 4, inner ring and bottom surface are all positioned in the groove of valve seat; Seat ring 4 and flap configure in pairs; The radial dimension of seat ring 4 is more than or equal to the radial dimension of described flap.
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.
