Abstract
The aim is to make the production and repair convenient and rapid, as well as saving money, time and man-power. This is done by providing one double sealing and replaceable valve to the cut-off valve, gate valve, check valve, butterfly valve, thermal insulation valve, angular valve with high, medium and low pressure. This invention modifies the previous design by supplying a replaceable upper and inner sealing ring. The upper ring is installed at the bottom of the valve cap barrel and fixed in the joint between the valve cap and stem by the packing seal and gland. The inner sealing ring is installed in the valve and fixed by the sleeve, valve cap or the pipe flange. It is sealed between the inner sealing ring and the valve with the gasket.
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, by medium in the sealing surface sealed pipe in flap and the valve body, the deficiency of this structure is to damage valves leakage owing to corrosion and wearing and tearing cause sealing surface easily.In case valves leakage must remove old valve and change, and has both increased cost of production, has strengthened recondition expense again, resource and environment very big waste and destruction have all been caused.
Summary of the invention
The object of the invention is exactly the deficiency that overcomes above-mentioned prior art, provide a kind of produce with maintenance all fast convenient and also save time, laborsaving, the replaceable valve of dual-sealing ring that saves money.
Feature of the present invention is seal ring and two interchangeable seal rings of inner seal ring on having increased on original valve, and last seal ring is installed in the filling tube bottom of valve gap, by packing seal, is fixed on valve gap and valve rod junction by Gland; Inner seal ring is contained in the valve body, fixes by sleeve and valve gap, or fixes by piping flange; Pass through gasket seal between inner seal ring and the valve body.
When last seal ring sealing surface damages back generation leakage, only need open valve gap and Gland, take out filler, replace with seal ring, can solve seal ring and damage the leakage problem that is caused.When the inner seal ring sealing surface damages back generation leakage, only need open valve gap or unload lower valve, take out inner seal ring and pad and change, can solve the valves leakage problem that causes after inner seal ring damages.
Last seal ring and inner seal ring all adopt zirconium oxide nano ceramics, stainless steel or copper product to make.The sealing ring material performance all improves a lot than original valve material at aspects such as wear-resistant, corrosion-resistant, high temperature resistant, resistance to deformations, therefore the working life of having improved valve greatly.
The present invention be applicable to stop valve, gate valve, safety check, ball valve, butterfly valve, thermal insulation valve, angle valve contour, in, Low pressure valve.Can adopt multiple driving mode such as manual, electronic, pneumatic, gear transmission, product is applied to industries such as oil, chemical industry, electric power.Seal ring of the present invention adopts the mode of processing separately, compares with the built-up welding sealing surface, and time saving and energy saving, the yield rate height is convenient to production and processing.And easy to maintenance quick, for the user reduces repair time and expense, can reduce the generation and the wasting of resources of steel scrap, alleviate environment damage.
Description of drawings
Fig. 1 is the stop valve structure schematic representation.
Fig. 2 is the gate valve structure schematic representation.
Among the figure: 1, valve body, 2, flap, 3, inner seal ring, 4, pad, 5, valve rod, 6, valve gap, 7, go up seal ring, 8, filler, 9, Gland, 10, handwheel, 11, sleeve.
Embodiment
Embodiment 1: be used for stop valve.Inner seal ring 3 is fixed on valve body 1 inner sleeve 11 bottoms by valve gap 6 and sleeve 11.Pad 4 is loaded between inner seal ring 3 bottoms and the valve body 1, rises to compress and seal action.When valve closing, sealing in producing between inner seal ring 3 sealing surfaces and flap 2 sealing surfaces prevents interior leakage.Last seal ring 7 is loaded on valve gap 6 stuffing holes bottom by filler 8 and Gland 9, is fixed on valve gap 6 and valve rod 5 junctions.During valve opening, produce between valve rod 5 and last seal ring 7 sealing surfaces and go up sealing, prevent to leak outside.Inner seal ring 3 can be machined directly to one with sleeve 11 and use.
Embodiment 2: be used for gate valve.Inner seal ring 3, pad 4 are fixed in the valve body 1 by piping flange, and when valve closing, sealing in producing between inner seal ring 3 sealing surfaces and flap 2 sealing surfaces prevents interior leakage.Last seal ring 7 is loaded on valve gap 6 stuffing holes bottom, is fixed on valve gap 6 and valve rod 5 junctions by filler 8 and Gland 9.During valve opening, produce between valve rod 5 and last seal ring 7 sealing surfaces and go up sealing, prevent to leak outside.
Claims (2)
