Abstract
The utility model relates to a large-flow safety valve of a hydro-generator. The large flow safety valve is arranged on a cover plate of a machine shell of the hydro-generator for utilization so as to exhaust air currents and release pressure in the machine when accidental fire occurs in the machine and gaseous fire suppression is started. The large-flow safety valve is composed of seat plates, an annular plate, limiting pins, a valve door plate, and an outer cover with a rhombus mesh. The outer cover with the rhombus mesh is fixed with the seat plates through screws. The limiting pins penetrate through pin holes in the valve plate and then enable the annular plate to be fixed with the seat plates through threads at the tail end of the limiting pins, screw holes in the annular plate and screw holes in the seat plates. The large-flow safety valve of the hydro-generator has the advantages of being simple in structure; utilizing self-gravity of the valve door plate as the opening pressure of the valve, so that opening pressure is free from any interference; being stable and reliable in working performance, and low in cost.
Description
Technical field
The utility model relates to the hydraulic turbine generator high-flow safety valve, be applied to be arranged on hydraulic turbine generator casing cover plate use so that in machine outside exhaust jet stream in time during unexpected startup extinction using gas on fire, give release in machine.
Background technique
For protection hydraulic turbine generator safety of equipment during unexpected startup extinction using gas on fire in machine, prevent contingency, need to install safety valve additional at the hydraulic turbine generator outer surface.The existing complex structural designs of protecting required high-flow safety valve for the hydraulic turbine generator extinction using gas, cost is high.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, and a kind of simple in structure, reliable and low hydraulic turbine generator high-flow safety valve of fabricating cost is provided.
The purpose of this utility model can realize by following technical proposals: the hydraulic turbine generator high-flow safety valve is characterized in that being comprised of seat board, ring flat-plate, position-limitting pin, valve plates, band rhombus net outer cover; Band rhombus net outer cover is fixed together by screw and seat board; Position-limitting pin is fixed together ring flat-plate and seat board by the screw thread of position-limitting pin end and the tapped hole on ring flat-plate and the tapped hole on seat board through the pin hole on valve plates again.
The utlity model has following advantage: simple in structure; Utilize the cracking pressure of valve plates self gravitation as valve, cracking pressure is not subject to any interference; Stable work in work, reliable, with low cost.
The accompanying drawing explanation
Accompanying drawing 1 is structural representation of the present utility model.
In figure, 1 is band rhombus net outer cover, the 2nd, and position-limitting pin, the 3rd, valve plates, the 4th, ring flat-plate, the 5th, seat board, the 6th, screw, the 7th, rhombus net.
Embodiment
The utility model is further described below in conjunction with accompanying drawing.The hydraulic turbine generator high-flow safety valve, be comprised of seat board (5), ring flat-plate (4), position-limitting pin (2), valve plates (3), band rhombus net outer cover (1).Band rhombus net outer cover (1) is fixed together by screw (6) and seat board (5).In band rhombus net outer cover (1) top-portion apertures, rhombus net is installed, preventing that exterior object from falling into affect valve plates (3) and works.Band valve hole, seat board (5) middle part.Position-limitting pin (2) is fixed together ring flat-plate (4) and seat board (5) by the screw thread of position-limitting pin end and the tapped hole on ring flat-plate and the tapped hole on seat board through the pin hole on valve plates (3) again.Ring flat-plate (4) is for rim valve plates (3), and area of contact is very little, to strengthen valve plates (3), makes the sensitivity of vertical motion along position-limitting pin.
During use, seat board (5) is connected with cover plate of generator by welding.When the generator accident is on fire, the suppression system action, at this moment the fire-suppressant gas pressure of airtight generator raises gradually.When the suffered gas load made progress of valve plates (3) is greater than the gravity of valve plates (3) self, valve plates (3) rises under the gas pressure effect, gas just moves and goes out the external world to band rhombus net outer cover (1) top rhombus net (7) through the valve hole, completes the timely release in machine.Otherwise, when the suffered gas load made progress of valve plates (3) is less than the suffered gravity of valve plates, valve plates (3) moves downward, drop on ring flat-plate valve hole closure, the utility model returns back to the working state of closing.
Claims (1)
1. the hydraulic turbine generator high-flow safety valve, is characterized in that being comprised of seat board (5), ring flat-plate (4), position-limitting pin (2), valve plates (3), band rhombus net outer cover (1); Band rhombus net outer cover (1) is fixed together by screw (6) and seat board (5); Position-limitting pin (2) is fixed together ring flat-plate (4) and seat board (5) by the screw thread of position-limitting pin end and the tapped hole on ring flat-plate and the tapped hole on seat board through the pin hole on valve plates (3) again.
