Abstract
The utility model relates to a safe diaphragm plate for a condenser, which aims to ensure that the safe diaphragm plate is normally and effectively used under the condition that the condenser is in a vacuum state, immediately acts to release the steam pressure under the condition of exceeding the pressure regulated in the condenser and has the advantages of safe equipment, simple structure, economy and practical use. The utility model adopts the technical scheme that the safe diaphragm plate for the condenser comprises a cone-shaped casing and a cylindrical tube body the end surfaces of which are oppositely connected; a butt clamp is arranged at the connection of the cone-shaped casing and the cylindrical tube body; the other two end surfaces of the cone-shaped casing and the tube body are respectively used as a steam inlet and a steam outlet; the diaphragm plate is tightly clung to a perforated plate fixed on the end surface of the casing; a sharp instrument is fixed in the tube body, and the pointed end thereof points to the diaphragm plate and keeps a certain distance of 3-6 mm with the diaphragm plate. A transverse bar is fixed on the inner wall of the tube body; and the sharp instrument is fixed on the transverse bar. The aperture of a small hole on the perforated plate is 20 mm. The periphery of the diaphragm plate is fixed on a butt-clamping connector for connecting the casing body and the tube body.
Description
Technical field
The utility model relates to a kind of safety guard of turbine condenser, i.e. condenser safety lamina membranacea.
Background technology
In the thermodynamic cycle of condensing turbine group, condensing equipment plays a part low-temperature receiver, and its main task is that turbine discharge is condensed into water and sets up and keep certain vacuum at the turbine discharge mouth.Condenser is topmost equipment in the condensing equipment, except that the steam discharge with steam turbine is condensed into the water boiler of feeding reuses, also sets up one far below atmospheric vacuum at the turbine discharge place down in that other equipment are auxiliary.The vacuum of condenser has significant impact to efficient, the power of steam-turbine plant, so the device that is connected with condenser should stop air to enter, under the steam turbine exhaust pressure normal condition, condenser is in vacuum state, when steam turbine exhaust pressure is a malleation and when surpassing the condenser authorized pressure, will have a negative impact to equipment, even jeopardize device security; At this moment, just need in time to discharge the interior steam of condenser.
The utility model content
Technical problem to be solved in the utility model provides a kind of condenser protective device; when should be able to making condenser be in vacuum state, normally uses effectively in this device; and can be when surpassing the condenser authorized pressure timely releases steam pressure, have device security, simple in structure, the economical and practical characteristics guaranteed.
The technical scheme that the utility model provides is: condenser safety lamina membranacea, comprise cone shape housing and columned body that the end face butt joint links to each other, both continuous junctions are provided with pressing from both sides a lamina membranacea, and two other end face of housing and body is respectively as steam inlet and steam (vapor) outlet; Described lamina membranacea is close to the porous plate that is fixed on the housing end face; Fix a sharp device in the body, the tip of sharp device is pointed to lamina membranacea and is kept the distance of 3-6mm with lamina membranacea.
Described inboard wall of tube body is fixed a horizontal stripe, is fixing described sharp device on the horizontal stripe.
Small aperture on the described porous plate is 20mm.
The periphery of described lamina membranacea be fixed on connect housing and body on the clipper joint.
Described lamina membranacea is aluminium flake or Stainless Steel sheet.
Operation principle of the present utility model is:
During operate as normal, steam turbine exhaust pressure is a negative pressure, and condenser is in vacuum state; Steam in the condenser enters condenser safety lamina membranacea import 1, but steam is stopped by lamina membranacea 6; Enter because condenser is in vacuum state and does not allow not coagulate air, and sealing ring 5 sealings are arranged, this moment, lamina membranacea was held by porous plate 4.When steam turbine exhaust pressure is malleation and when surpassing the condenser authorized pressure during safe lamina membranacea setting pressure; steam is by the aperture on the porous plate 4; make lamina membranacea 6 upwards bloat and then punctured by sharp device 12; steam is promptly arranged the housing B that enters column; and discharge into the atmosphere (or by take over straight-through atmosphere), and then protected device security by steam drain 13.Lamina membranacea 6 after breaking by unclamping weld assembly 10 connector and unclamp lamina membranacea to clipper joint 7, can realize changing.
The beneficial effects of the utility model are:
1. can protect the safe operation of condenser and whole steam turbine and condensing system, prevent that superpressure from causing accident.
2. condenser safety diaphragm panel assembly is simple in structure, and the lamina membranacea replacement cost is low thereby economical and practical.
The figure explanation of bowing
Fig. 1 is a main TV structure schematic diagram of the present utility model.
Fig. 2 is a plan structure schematic diagram of the present utility model.
The specific embodiment
As shown in the figure, condenser safety lamina membranacea comprises cone shape housing A and columned body B, and cone shape housing is combined by straight tube 2, Taper Pipe 3 and porous plate 4 welding, and the bottom is as air intake 1; Columned body makes up by clipper joint 7, straight tube 15 and end face shrouding 14 are welded, and is connected with weld assembly 10, column jecket 11 by connector, and the top is as steam drain 13.
The inner chamber of body is provided with a horizontal stripe 9, this horizontal stripe (metal is made) is fixed on the internal chamber wall portion (normally passing through the body center of column) near lamina membranacea 6, and sharp device 12 is housed in the center, the tip of sharp device is pointed to lamina membranacea and is kept suitable distance (generally being 3-6mm) with lamina membranacea; Horizontal stripe 9 is by being connected with lug 8 on the column inboard wall of tube body, and lug is fixed on the inwall of (generally being that welding is fixing) straight tube 15.The end face connecting place of body and housing is to pressing from both sides a lamina membranacea 6, and by connector that lamina membranacea 6 and seal 5 (rubber seal) is fastening together; Connector by unclamping weld assembly 10 and unclamp lamina membranacea 6 can realize the transposing of lamina membranacea to clipper joint 7.
Claims (5)
1. condenser safety lamina membranacea, it is characterized in that this safe lamina membranacea comprises cone shape housing (A) and columned body (B) that the end face butt joint links to each other, both continuous junctions are provided with pressing from both sides a lamina membranacea (6), and two other end face of housing and body is respectively as steam inlet (1) and steam (vapor) outlet (13); Described lamina membranacea (6) is close to the porous plate (4) that is fixed on the housing end face; Also fix a sharp device in the body, the tip of sharp device is pointed to lamina membranacea and is kept the distance of 3-6mm with lamina membranacea.
