Description

A kind of sand discharge safety check
Technical field
A kind of sand discharge safety check of the utility model, belongs to sand discharge technical field of drawing water.
Background technique
The farm buildings of some remote districts or the factory built do not have tap water or water service not enough; need to carry out drawing water from river or in deep-well supplying, and usually all contain the grains of sand in river or deep-well, therefore; after a shutdown; water in water pipe and sand are back in pump, then discharge, and reverse to prevent water pump; burn out motor; generally all be provided with safety check on water pump top, safety check has two weep holes, and water is oozed.If it is comparatively large to go out husky amount, general safety check can be blocked by sand, cannot run well, thus make equipment out of use, increases maintenance cost, in sum, needs to improve existing equipment.
Model utility content
In order to overcome the deficiencies in the prior art, providing that a kind of structure is simple, sand discharge is convenient, a kind of sand discharge safety check of energy-conserving and environment-protective.
In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is:
A kind of sand discharge safety check, comprise the pump housing and only husky valve, comprise inner chamber and exocoel in the described pump housing, inner cavity is provided with sliding sleeve, and only the top of husky valve is sleeved in sliding sleeve, and inner chamber is by opening passage on the right side of the pump housing and ft connection.
Described sliding sleeve and only husky valve are for being slidably connected.
The bottom of described only husky valve is protruding sphere.
The beneficial effect that the utility model is compared with prior art had is:
The utility model sand discharge safety check is by stopping the effect of husky valve, when stopping pumping, the freely falling body of water is utilized to have a downward pressure, water intake has been blocked again in water check valve free fall, the grains of sand are taken out of from the passage of pump housing side by water, when again opening pump, by the pressure automatic cut-off only husky valve of water, and reach water object.The utility model structure is simple, and sand discharge is convenient, takes full advantage of the pressure that water is downward, energy-conserving and environment-protective in sand discharge process.
Accompanying drawing explanation
Below by accompanying drawing, embodiment of the present utility model is described in further detail.
Fig. 1 is structural representation of the present utility model.
In figure, 1 is that the pump housing, 2 is sliding sleeve, 5 is passage for husky valve, 4 till inner chamber, 3.
Embodiment
The utility model will be further described by reference to the accompanying drawings for embodiment below.
As shown in Figure 1, a kind of sand discharge safety check, comprise the pump housing 1 and only husky valve 3, comprise inner chamber 2 and exocoel in the described pump housing 1, inner chamber 2 inside is provided with sliding sleeve 4, and only the top of husky valve 3 is sleeved in sliding sleeve 4, and inner chamber is by opening passage 5 on the right side of the pump housing 1 and ft connection.
Described sliding sleeve 4 and only husky valve 3 are for being slidably connected.
The bottom of described only husky valve 3 is protruding sphere.
When drawing water, the grains of sand enter along with the lower end water intake of water from the pump housing 1, impact due to water will stop husky valve 3 jack-up, flow out, when stopping pumping from the water outlet of the pump housing 1 upper end, only husky valve 3 freely falls and blocks water intake, now, because the water stopping husky valve 3 upper end freely falls, downward pressure is had, by the grains of sand that drop in the pump housing 1 through inner chamber 2, flow out from passage 5.
The utility model structure is simple, and sand discharge is convenient, Action of Gravity Field more can be utilized to be discharged by the grains of sand in the pump housing 1, energy-conserving and environment-protective, and coated only husky valve 3 upper end of sliding sleeve 4, makes the work that only husky valve 3 can be more stable.
