The invention has the aims that the replaceable type valve of the vacuum sealing ring can be recycled, and the production and the repair are convenient; the replaceable type valve of the vacuum sealing ring, which is disclosed by the invention, comprises a valve clack, a sealing ring of a valve seat, a supporting spring, a vacuum sealing ring, a locking nut, a vacuum conduit, a choke plug, a piston body, a piston, a hand wheel, a nut of a valve rod, a packing gland, a packing, a shim, the valve rod and a valve body; the valve clack is positioned in the valve body, and the sealing ring of the valve seat and the supporting spring are arranged below the valve clack; the sealing ring of the valve seat is seated on the vacuum sealing ring; a vacuum groove is arranged in the vacuum sealing ring, and a sealing step matched with the vacuum groove of the vacuum sealing ring is arranged on the sealing ring of the valve seat; the vacuum sealing ring is positioned in the valve body by the locking nut; the vacuum conduit is screwed on the valve body by screw threads, and an inner hole of the vacuum conduit is communicated with the vacuum groove of the vacuum sealing ring; the outer end of the vacuum conduit is provided with the choke plug for sealing; and the outside of the vacuum conduit is provided with the piston body and the piston, and the choke plug is arranged on the piston.
Description
Technical field
The present invention relates to a kind of seal ring replaceable valve.
Background technique
Existing valve mostly is disposable single sealed valve; The sealing surface of these valves adopts built-up welding or drive fit mode to be fixed in the valve body; Through medium in the sealing surface of seat sealed pipe in flap and the valve body; The deficiency of this structure is to damage owing to corrosion and wearing and tearing cause sealing surface easily, leaks in valve produces.In case valves leakage must remove old valve and change, and has both increased cost of production, has strengthened recondition expense again, has wasted a large amount of raw material, also resource and environment very big waste and destruction have been caused.
Summary of the invention
The object of the invention is exactly the deficiency that overcomes above-mentioned prior art, provides a kind of and can be recycled, is convenient to the vaccum seal ring replaceable valve producing and keep in repair.
The present invention includes flap, valve seat insert and top spring, vaccum seal ring, locknut, vacuum piping and plug, piston body and piston, handwheel, Stem Mut, Gland, filler and pad, valve rod and valve body.Flap is positioned at valve body, is provided with valve seat insert and top spring below the flap; The valve base sealing ring support is on vaccum seal ring; Be provided with vacuum tank in the vaccum seal ring, valve seat insert is provided with the sealed step that matches with the vaccum seal ring vacuum tank; The top spring is fixed on the below of valve seat insert, together is pressed in the vacuum tank with valve seat insert; Vaccum seal ring is positioned in the valve body through locknut; Vacuum piping is screwed on the valve body through screw thread, and the vacuum piping endoporus is communicated with the vaccum seal ring vacuum tank; The vacuum piping outer end is provided with sealing and uses plug; Piston body and piston are equipped with in the vacuum piping outside, and plug is contained on the piston.Can get rid of the air in the vaccum seal ring vacuum tank through piston, make to produce the negative pressure of vacuum sealing between valve seat insert and the vaccum seal ring, valve seat insert is fixed.The top spring plays the role of positioning to valve seat insert.Valve seat insert, vaccum seal ring can adopt the materials processing of various materials such as rubber, alloy, stainless steel, pottery.
The present invention is applicable to high, medium and low pressure valves such as stop valve, gate valve, safety check, ball valve, butterfly valve, thermal insulation valve, angle valve.Can adopt multiple driving mode such as manual, electronic, pneumatic, gear transmission, product is applied to industries such as oil, chemical industry, chemical fertilizer, Coal Chemical Industry, electric power, Aluminum.Product of the present invention is convenient to production and processing, and is easy to maintenance quick, time saving and energy saving, can be recycled, and improves working life, can be the user and reduces repair time and expense, reduces the generation of steel scrap, reduces the wasting of resources, alleviates environment damage.Be the low carbon products of a kind of energy-conserving and environment-protective that can be recycled.
Description of drawings
Fig. 1 is a stop valve Facad structure schematic representation.
Fig. 2 is a stop valve side structure schematic representation.
Among the figure: 1, flap, 2, valve seat insert, 3, the top spring, 4, vaccum seal ring, 5, locknut; 6, Gland, 7, Stem Mut, 8, handwheel, 9, valve gap, 10, vacuum tank; 11, valve body, 12, the filler pad, 13, valve rod, 14, filler, 15, jackscrew; 16, piston plug, 17, piston, 18, piston body, 19, vacuum piping.
Embodiment
The example that is applied as with on the stop valve describes: handwheel 8 is contained in valve rod 13 upper ends, and Stem Mut 7 is loaded on the valve gap 9, and valve gap 9 is loaded on the valve body 11, and through jackscrew 15 location.Gland 6 compresses filler 14, sealed valve stem 13, and 12 pairs of fillers 14 of filler pad play a supportive role.Flap 1 is equipped with in valve rod 13 lower ends, is between flap 1 and the valve seat insert 2 dynamic seal (packing) to play the sealing medium effect.Vaccum seal ring 4 is positioned in the valve body 11 through locknut 5; Vacuum piping 19 is screwed on the valve body 11 through screw thread, and vacuum piping 19 endoporus are communicated with vaccum seal ring vacuum tank 10; Vacuum piping 19 outer ends are provided with sealing with piston plug 16; Piston body 18 and piston 17 are equipped with in vacuum piping 19 outsides, and piston plug 16 is contained on the piston 17.Can get rid of the air in the vacuum tank 10 through piston 17, valve seat insert 2 and vaccum seal ring 4 static sealings play 2 effects of fixed valve base seal ring.Top spring 3 is welded on the two sides of valve seat insert 2 sealed step small ends, together is pressed in the vacuum tank 10 with valve seat insert 2, plays the role of positioning.
In the use, when producing interior the leakage if the sealing surface of valve seat insert 2 damages to some extent, can open valve gap 9, taking-up flap 1 is opened the piston plug 16 outside the valve body 11, puts into air, and valve seat insert 2 releasings and the negative pressure of vacuum of vaccum seal ring 4 are sealed; Treat that the loosening back of valve seat insert 2 is taken out and change or safeguard, make valve in time reply normal the use, need not to change valve.
