Abstract
The utility model discloses a high-pressure check valve which comprises a valve body (1), a spray nozzle (2), a sliding sleeve (3), a valve rod (4), a valve disk (5), a spring (7) and a seat ring (8). The high-pressure check valve is characterized in that an discharge orifice (6) is formed on the valve disk (5). The discharge orifice of the high-pressure check valve has the function of discharge and pressure relief, thereby being able to relieving the huge impact force of the water hammer and ensuring the safety of the drainage system, therefore, the high-pressure check valve is especially suitable to be applied in high-power, suspension type, high-flow, or high-delivery lift drainage systems for emergency rescue and disaster relief of mines.
Description
Technical field
The utility model relates to rescue and relief work draining field, mine, particularly a kind of pipeline check valve of high-lift pump.
Background technique
In the rescue and relief work system, because the extension of mine, the down-hole water yield is big, complexity environment such as lift height, and the application of high-power, suspension type, big flow, high-lift rescue and relief work drainage system has become trend.When high-lift pump is shut down, can form huge impact of water hammer power, the Security of drainage system is caused very big threat.
Summary of the invention
The overweight a kind of high pressure check valve that provides of water hammer pressure that the purpose of this utility model causes owing to shutdown at large-scale rescue and relief work drainage system, the enormous impact power of having slowed down water hammer.
The purpose of this utility model can realize by following technique measures:
A kind of high pressure check valve that the utility model provides comprises valve body, nozzle, sliding sleeve, valve rod, valve disc, spring, seat ring.Described valve rod can slide up and down in sliding sleeve, and valve rod and valve disc are fixed as integral body, it is characterized in that being equipped with on the valve disc some discharge orifices.
The beneficial effects of the utility model are as follows:
A kind of high pressure check valve that the utility model provides; after water pump is shut down; in the current decline process; discharge orifice on the valve disc has the earial drainage decompression; slow down the enormous impact power of water hammer; guarantee the Security of drainage system, be particularly suitable for the application of high-power, suspension type, big flow, high-lift rescue and relief work drainage system.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
Fig. 1 is a sectional view of the present utility model.
Fig. 2 is a working state sectional view of the present utility model.
Be labeled as among the figure: 1: valve body; 2: nozzle; 3: sliding sleeve; 4: valve rod; 5: valve disc; 6: discharge orifice; 7: spring; 8: seat ring.
Arrow is a water (flow) direction among the figure.
Embodiment
The utility model is further described below with reference to embodiment's (accompanying drawing):
As Fig. 1 is a kind of high pressure check valve of the utility model.Valve body 1 is fixedly arranged on pump outlet and pipeline junction.Valve body 1 internal fixation nozzle 2, nozzle 2 internal fixation sliding sleeves 3; Valve rod 4 and valve disc 5 are fixed as integral body, and between establishes a spring 7, and spring 7 acts on valve rod 4 and it is slided up and down in sliding sleeve 3; Seat ring 8 is fixed on the peripheral region of valve body 1 open lower side; Be equipped with some discharge orifices 6 on the valve disc 5, have the earial drainage decompression.
As Fig. 2 is the utility model working state figure, shuts down when water pump, moves to valve disc 5 places of check valve under the current direction, and by the earial drainage decompression of discharge orifice 6, the enormous impact power of having slowed down water hammer has guaranteed the safety of drainage system to have reduced unnecessary loss.
