Abstract
The invention discloses a valve seat assembling tool for a valve. A spring claw (3) is fixed at an end of a sleeve (5) through spot welding and extends out of an end face of the sleeve (5) for a certain length; a stud bolt (2) is arranged on an inner wall at the other end of the sleeve (5) through a bushing (7); the stud bolt (2) passes through the sleeve (5) and extends out of the sleeve and is positioned on the sleeve (5) through a locking nut (6); a gasket (4) is arranged on an outer wall of the sleeve (5) and contacts with the locking nut (6); a core shaft (1) is arranged on the stud bolt (2) on the same side of the spring claw (3); an outer conical wall of the core shaft (1) is contacted with the spring claw (3); and a hexagonal nut (8) is arranged on the stud bolt (2) on the other side of the spring claw (3). By assembling the valve by adopting a taper tension and thread transmission mode, the valve seat assembling tool does not damage a sealing surface between the valve seat and a valve plate, guarantees the excellent quality of the valve, improves the assembling efficiency and saves the cost.
Description
Technical field
The present invention relates to assembly tool, relate in particular to a kind of seat assembling tool for valve of valve of flap type band wavy spring.
Background technology
In the assembling process of valve, 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, the size and the service life of switch torsion.At present, the assembling of valve seat is to finish with simple aid basically, and what the valve body and valve seat hole cooperated employing with valve seat is very little matched in clearance, be difficult to be in place, and assembling is inconvenient, efficiency of assembling is low, the valve mass of installing is not high, influences the serviceability of valve.
Summary of the invention
The objective of the invention is to: a kind of seat assembling tool for valve of valve is provided, and it is simple, efficient to make that by this assembly tool the assembling of valve becomes, and guarantees the installation quality of valve simultaneously.
Technical solution of the present invention is: this assembly tool comprises mandrel, stud, spring detent, pad, sleeve, locking nut, lining and hex nut, spring detent spot welding is fixed on the end of sleeve, spring detent stretches out the sleeve end face certain-length, the other end inwall of sleeve is by the lining mounting stud, stud connects sleeve and stretches out sleeve, stud is positioned on the sleeve through locking nut, on the outer wall of sleeve pad is installed, pad contact locking nut, on the stud of spring detent homonymy mandrel is installed, the outer cone wall contact spring pawl of mandrel is installed hex nut on the stud of spring detent opposite side.
During installation, wavy spring is installed in two valve seat orifice of putting into the valve body symmetry on the cylindrical step of valve seat end face together; During use, regulate earlier the hex nut of assembly tool, that removes mandrel and spring detent contacts tapering trip spring pawl; Then two wing passages of the spring detent of assembly tool by valve body are stretched in the valve seat orifice, pad is close on the flange outer face of valve body; Then inwardly rotate hex nut, by the screw thread transmission, mandrel moves, and magnifies spring detent, the tensioner valve seat; Secondly screw locking nut inward, move outward by the lining by screw thread transmission two valve seats, until putting into valve plate; Screw hex nut at last outward, reduce the tapering contact-making surface of mandrel and spring detent, spring detent breaks away from valve seat orifice, takes out assembly tool, finishes the assembling of valve seat, valve plate.
The present invention has the following advantages:
1, the present invention adopts tapered expanding, screw thread kind of drive assembling valve, location tension two valve seats and compressed waveform spring, and the sealing surface of valve seat and valve plate is not under any damage, and has guaranteed the excellent quality of valve, and has improved efficiency of assembling, has saved cost.
2, the present invention is simple in structure, and is easy to operate, and it is simple, efficient to make that the assembling of valve becomes.
Description of drawings
Fig. 1 is the general assembly drawing of the seat assembling tool for valve of valve body
Fig. 2 is the use schematic diagram of the seat assembling tool for valve of valve body
Among the figure: 1 mandrel, 2 studs, 3 spring detents, 4 pads, 5 sleeves, 6 locking nuts, 7 linings, 8 hex nuts, 9 valve bodies, 10 valve plates, 11 valve seats, 12 wavy springs.
The specific embodiment
As shown in Figure 1, this assembly tool comprises mandrel 1, stud 2, spring detent 3, pad 4, sleeve 5, locking nut 6, lining 7 and hex nut 8, spring detent 3 spot welding are fixed on the end of sleeve 5, spring detent 3 stretches out sleeve 5 end face certain-lengths, the other end inwall of sleeve 5 is by lining 7 mounting studs 2, stud 2 connects sleeve 5 and stretches out sleeve, stud 2 is positioned on the sleeve 5 through locking nut 6, pad 4 is installed on the outer wall of sleeve 5, pad 4 contact locking nuts 6, mandrel 1 is installed on the stud 2 of spring detent 3 homonymies, and the outer cone wall contact spring pawl 3 of mandrel 1 is installed hex nut 8 on the stud 2 of spring detent 3 opposite sides.
As shown in Figure 2, during installation, wavy spring 12 is installed in two valve seat orifice of putting into valve body 9 symmetries on the cylindrical step of valve seat 11 end faces together; During use, regulate earlier the hex nut 8 of assembly tool, that removes mandrel 1 and spring detent 3 contacts tapering trip spring pawl 3; Then two wing passages of the spring detent 3 of assembly tool by valve body 9 are stretched in the valve seat orifice, pad 4 is close on the flange outer face of valve body 9; Then inwardly rotate hex nut 8, by the screw thread transmission, mandrel 1 moves, and magnifies spring detent 3, tensioner valve seat 11; Secondly screw locking nut 6 inward, move outward by the lining by screw thread transmission two valve seats 11, until putting into valve plate 10; Screw hex nut 8 at last outward, reduce the tapering contact-making surface of mandrel 1 and spring detent 3, spring detent 3 breaks away from valve seat orifice, takes out assembly tool, finishes the assembling of valve seat 11, valve plate 10.
