Abstract
An improved thin-casing drainage valve belongs to the technical field of valves. A steam inlet joint is welded on an upper thin casing, a water outlet joint is welded on a lower thin casing, a seal pair comprising a seal belt and a seal ball is arranged in the water outlet joint, the seal ball is riveted and fixed on a valve rod, a tightening nut capable of adjusting the clearance with an upper sheet is mounted at the upper end of the valve rod, and the seal performance between the seal ball and the seal belt can be ensured; the upper sheet and a double metal sheet group are fixed on a strong-rigidity support plate by a bolt and a nut, and are welded together with the water outlet joint; and the upper and the lower thin casings are sealed and welded together. Compared with the prior art, the support plate is welded on the water outlet joint, and the double metal sheet group is fixed on the support plate through a fastening piece, so that the support plate is prevented from deformation under the steam pressure, the clearance after adjustment keeps unchanged, no steam leaks during the use process of the thin-casing drainage valve, and the energy is saved.
Description
Technical field
The utility model relates to improved thin-shell type drain valve, belongs to valve technology field.
Background technique
The thin-shell type drain valve is to introduce Canadian Velan S. A. S. product, and this product is used on the steam pipe line, can reach the effect of draining resistance vapour, energy saving.The thin-shell type drain valve structure of introducing comprises Intaking joint, goes up thin walled shell, water output connector, down thin walled shell, ball sealer, valve rod, tighten nut, last slice, bimetallic strip group, bolt, nut and base, wherein bolt, nut with last slice, the bimetallic strip group is fixed on the base, the thin-shell type drain valve is formed in thin walled shell soldering and sealing together up and down.The greatest drawback of this kind thin-shell type drain valve is: in high pressure steam enters valve, thin walled shell distortion up and down, gap after adjusting is changed, thereby make the sealing force of sealing pair reduce, cause thin-shell type drain valve when work steam leakage, by standard-required steam leakage amount exceed standard (seeing figure one).
Summary of the invention
In view of the defective that prior art exists, the purpose of this utility model provides a kind of steam does not in use have leakage, reach standard-required, the improved thin-shell type drain valve of energy saving.
For achieving the above object, the utility model solves by the following technical programs: improved thin-shell type drain valve, Intaking joint is welded on the thin walled shell, water output connector is welded on down on the thin walled shell, form sealing pair by sealing strip and ball sealer in the water output connector, the ball sealer rivet clasp is on valve rod, valve rod upper end is installed and is tightened nut and can regulate gap between the same, guarantee the sealability between ball sealer and the sealing strip, pass through bolt, nut is with last slice, the bimetallic strip group is fixed on the strong supporting plate of rigidity, and and water output connector welding together, thin walled shell soldering and sealing is together up and down.
The utility model compared with prior art, because supporting plate is welded on the water output connector, the bimetallic strip group is fixed on the supporting plate by fastening piece again, can not be out of shape at the vapor pressure bottom plate, guarantee that adjusted gap can not change, guarantee that steam does not have leakage, energy saving in the using process of thin-shell type drain valve.
Description of drawings
Fig. 1 is a thin-shell type drain valve structural representation of introducing Canadian Velan S. A. S.;
Fig. 2 is improved thin-shell type drain valve structural representation.
Among the figure: 1, Intaking joint, 2, tighten nut, 3, go up thin walled shell, 4, last slice, 5, the bimetallic strip group, 6, valve rod, 7, ball sealer, 8, thin walled shell down, 9, water output connector, 10, bolt, 11, nut, 12, base, 13, supporting plate.
Embodiment
Fig. 1 introduces in the thin-shell type drain valve structural representation of Canadian Velan S. A. S., structure comprises Intaking joint 1, goes up thin walled shell 3, water output connector 9, down thin walled shell 8, ball sealer 7, valve rod 6, tighten nut 2, last slice 4, bimetallic strip group 5, bolt 10, nut 11 and base 12, wherein bolt 10, nut 11 with last slice 4, bimetallic strip group 5 is fixed on the base 12, the thin-shell type drain valve is formed in last thin walled shell 3 and following thin walled shell 8 soldering and sealing together.
In the improved thin-shell type drain valve of Fig. 2 structural representation, Intaking joint 1 is welded on the thin walled shell 3, water output connector 9 is welded on down on the thin walled shell 8, form sealing pair by sealing strip and ball sealer 7 in the water output connector 9, ball sealer 7 rivet clasps are on valve rod 6, valve rod 6 upper ends are installed and to be tightened nut 2 and can regulate gap between the same 4, guarantee the sealability between ball sealer 7 and the sealing strip, by bolt 10, nut 11 is with last slice 4, bimetallic strip group 5 is fixed on the strong supporting plate of rigidity 13, and and water output connector 9 welding together, last thin walled shell 3 is in the same place with following thin walled shell 8 soldering and sealing.
The operating principle of the improved thin-shell type drain valve of Fig. 2 is:
1) bimetallic strip at normal temperatures (Celsius 18 degree) be plane shape, beginning upwarping distortion behind the temperature influence, monolithic upwarping deformation force is very little, in order to obtain very big power, needs multi-disc to be superimposed and forms bimetallic strip group 5.The adjusting play is according to the saturated vapour characteristic, measures the gap by thickness gages, and the gap is adjusted excessive, and sealing force is just little, steam leakage will occur; The gap is adjusted too small, and sealing force is just big, and it is little the condensed water discharging to occur, causes the untimely discharge of condensed water in the pipeline, and the system that influences normally moves.
2) in steam enters valve, bimetallic strip group 5 begin to heat up a upwarping distortion and drive slices 4, tighten nut 2, valve rod 6, ball sealer 7 moves upward together, bimetallic strip group 5 upwarping power, ball sealer 7 is sealed tightly on the sealing strip in water output connector 9, the steam that enters in the valve just is blocked, vapor (steam) temperature in the valve is subjected to the influence of ambient temperature, vapor (steam) temperature descends and generates condensed water, condensed water increases gradually descends bimetallic strip group 5 temperature, the flexural force of bimetallic strip group 5 reduces, sealing force on the ball sealer 7 also reduces, and condensed water is by water output connector 9 discharging atmosphere or recovery under the pressure of steam.After draining, condensed water in the valve body is full of steam again, bimetallic strip group 5 begin again to heat up upwarping distortion and drive slices 4, tighten nut 2, valve rod 6, ball sealer 7 move upward together, ball sealer 7 is sealed tightly on the sealing strip in water output connector 9, the steam that enters in the valve is blocked again, like this, steam and condensed water be alternation repeatedly, and it is capable to make drain valve constantly carry out draining resistance automotive.
