Abstract
The utility model discloses the fixed water intake ball valve of a kind of water turbine with lumen concora crush, relate to a kind of water intake ball valve, to comprise before main valve, spheroid, valve expansion bend after connecting tube and valve, described spheroid is assemblied in described main valve, expansion bend after connecting tube and valve is connected before described valve respectively before and after described main valve, before described valve after connecting tube and valve between expansion bend also by bypass UNICOM, described bypass is also by branch road and described main valve valve lumen UNICOM, and the described bypass before described valve between connecting tube and described branch road is provided with valve.The utility model is that a kind of life-span is longer, the fixed water intake ball valve of water turbine of safety and reliability.
Description
Technical field
The utility model relates to a kind of water intake ball valve, particularly relates to water turbine Special fixing fixed pattern water intake ball valve.
Background technique
Before and after the hydroturbine water intake ball valve of water power plant and liaison of penstock, valve and spiral case Flange joint.The effect of inlet valve: pass through the current in this valve cut-out pressure steel pipe on the one hand when water turbine and maintenance for generation companies, ensure the safety of maintenance, effectively can cut off current, the generation of Accident prevention when exception appears in water turbine and generator on the other hand.
The deficiency that existing fixed water intake ball valve exists:
Existing fixed water intake ball valve needs to open bypass valve and carries out bath concora crush to after valve in opening process, and when downstream pressure is almost equal with before valve, main valve just can carry out valve opening action.Existing ball valve has only carried out bath concora crush to after valve, and this makes main valve lumen almost not have pressure, and now valve seat can produce very large pressure under the double action of spring and hydraulic pressure, and valve opening moment is increased, and prooving of valve seat aggravation, valve bulk life time shortens.
Model utility content
The purpose of this utility model is: propose a kind of life-span longer, the fixed water intake ball valve of water turbine of safety and reliability.
The purpose of this utility model is realized by following technical proposals:
The fixed water intake ball valve of a kind of water turbine with lumen concora crush, to comprise before main valve, spheroid, valve expansion bend after connecting tube and valve, described spheroid is assemblied in described main valve, expansion bend after connecting tube and valve is connected before described valve respectively before and after described main valve, before described valve after connecting tube and valve between expansion bend also by bypass UNICOM, described bypass is also by branch road and described main valve valve lumen UNICOM, and the described bypass before described valve between connecting tube and described branch road is provided with valve.
As selection, described valve is the hand by-pass valve of series connection and electronic bypass valve.
The main scheme of aforementioned the utility model and each further selection scheme thereof can independent assortment to form multiple scheme; be the utility model can adopt and claimed scheme; those skilled in the art can understand there is multiple combination according to prior art and common practise after understanding the present invention program; be the claimed technological scheme of the utility model, do not do exhaustive at this.
In the utility model, the effect of each part is as follows: be connected with valve lumen by adding a road branch road in water intake ball valve bypass course of action, and simultaneously valve is located in the bypass before valve between connecting tube and branch road, make in while concora crush.Solve the problem of existing water intake ball valve lumen without surge suppressor.
The beneficial effects of the utility model:
(1) reduce the wearing and tearing of valve seat greatly, longer seat life obtains prolongation, safe and reliable.
(2) reduce the moment of valve, such drive unit is littlely optional, has saved cost.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model embodiment;
In figure, 1 is main valve, and 2 is spheroid, and 3 is connecting tube before valve, and 4 is expansion bend after valve, and 5 is bypass, and 6 is branch road, and 7 is hand by-pass valve, and 8 is electronic bypass valve.
Embodiment
Below in conjunction with specific embodiments and the drawings, the utility model is further described.
As shown in Figure 1, the fixed water intake ball valve of a kind of water turbine with lumen concora crush, to comprise before main valve 1, spheroid 2, valve expansion bend 4 after connecting tube 3 and valve, spheroid 2 is assemblied in main valve 1, respectively expansion bend 4 after connecting tube 3 and valve before connection valve before and after main valve 1, before valve after connecting tube 3 and valve between expansion bend 4 also by bypass 5 UNICOM, bypass 5 also by branch road 6 and main valve 1 valve lumen UNICOM, the bypass 5 before valve between connecting tube 3 and branch road 6 is established hand by-pass valve 7 and the electronic bypass valve 8 of series connection.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection domain of the present utility model.
Claims (2)
1. one kind has the fixed water intake ball valve of water turbine of lumen concora crush, it is characterized in that: to comprise before main valve, spheroid, valve expansion bend after connecting tube and valve, described spheroid is assemblied in described main valve, expansion bend after connecting tube and valve is connected before described valve respectively before and after described main valve, before described valve after connecting tube and valve between expansion bend also by bypass UNICOM, described bypass is also by branch road and described main valve valve lumen UNICOM, and the described bypass before described valve between connecting tube and described branch road is provided with valve.
2. there is the fixed water intake ball valve of water turbine of lumen concora crush as claimed in claim 1, it is characterized in that: described valve is the hand by-pass valve of series connection and electronic bypass valve.
