Abstract
The invention discloses a spring pressing type valve seat for a stop valve, and belongs to the technical field of a valve seat component. The valve seat is characterized by comprising valve seat rings and spring components, wherein a slot is formed in the valve seat, and the valve seat rings are fixedly arranged in the slots of the valve seats through the spring components. According to the spring pressing type valve seat provided by the invention, the function of changing the valve seat components in pairs can be realized after the valve seat ring is damaged; meanwhile, the valve seat rings and valve clacks can be matched in pairs, and the pre-tightening force of the springs can be ensured according to the pressure grade.
Description
Technical field
The present invention relates to a kind of spring top pressure type valve seat for stop valve, belong 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.
Summary of the invention
The object of this invention 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 present invention 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 present invention 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 invention.
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 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 spring top pressure type valve seat for stop valve, it is characterized in that, comprises 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.
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 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.
