Description
Technical field
The utility model relates to a kind of supercharging pump of cutting off the water supply.
Background technique
Suction booster is as a kind of general fluid pressurized equipment, and in use general the employing cut off the water supply solenoid valve as the water route control unit, cuts off the function in water route when shutting down with the realization suction booster.Because its circuit, pipeline are all deposited, exist and complexity is installed and is unfavorable for reducing the deficiency of system cost, and be subjected to the restriction of the peculiar structure of solenoid valve, its reliability of cutting off the water supply is not high yet.
Existing a kind of Chinese patent application that is recorded in number is a water pump in 200720078160.3 the application documents, comprise the pump head that has hyperbaric chamber, water-inlet cavity in it, outlet pipe extends in the hyperbaric chamber, water-inlet cavity is communicated with water intake, be provided with the seal membrane that its front and rear end is subjected to hyperbaric chamber, water-inlet cavity hydraulic action respectively outside the internal orifice of described outlet pipe, the front-end face of sealing diaphragm has relative sealing head with the outlet pipe internal orifice, and is provided with resilient member between end face and the pump head thereafter.When supercharging is cut off the water supply pump when being in outage state, because the hyperbaric chamber, the hydraulic pressure in the water-inlet cavity that act on the described seal membrane front and rear end equate, the suffered elastic force of ear end face make its drive sealing head near the internal orifice of outlet pipe until sealing, thereby cut off the function in water route when realizing cutting off the water supply supercharging pump being shut down; When supercharging is cut off the water supply pump when being in open state, hydraulic pressure is higher than hydraulic pressure in the water-inlet cavity in the hyperbaric chamber, the suffered water pressure of seal membrane front-end face makes it drive sealing head and removes the outlet pipe internal orifice after overcoming the suffered elastic force of ear end face, thereby realizes opening when the pump start is cut off the water supply in supercharging the function in water route.But because seal membrane is subjected to the surface of hyperbaric chamber, water-inlet cavity hydraulic action and the surface of sealing head sealing outlet pipe internal orifice all to be positioned at same plane, therefore vibrations are bigger when water pump start operation.
The model utility content
Technical problem to be solved in the utility model provides a kind of supercharging of cutting off the water route function when shutting down automatically and being difficult for vibrations pump of cutting off the water supply that has.
The technical scheme in the invention for solving the above technical problem is: the supercharging pump of cutting off the water supply, comprise and have hyperbaric chamber in it, the pump head of low-pressure cavity, outlet pipe extends in the hyperbaric chamber, low-pressure cavity is communicated with water intake, outlet pipe is communicated with water outlet, before the internal orifice of described outlet pipe is outside equipped with, ear end face is subjected to hyperbaric chamber respectively, the seal membrane of low-pressure cavity hydraulic action, be provided with resilient member between seal membrane ear end face and the pump head, outlet pipe internal orifice place also is provided with the water shutoff seat, the water shutoff seat has at least one water port, the periphery of described seal membrane is fixed on pump head, and the seal membrane center is fixed on the water shutoff seat.
The periphery of seal membrane is fixed on pump head, when water pump is opened, hydraulic pressure is higher than hydraulic pressure in the water-inlet cavity in the hyperbaric chamber, the suffered water pressure of seal membrane front-end face is after overcoming the suffered elastic force of ear end face, because the seal membrane center is fixed on the water shutoff seat, therefore the periphery of seal membrane is removed the water port at outlet pipe internal orifice place earlier, along with the continuous service seal membrane of water pump is removed the water port at outlet pipe internal orifice place by periphery to the center gradually, thereby realize opening when the pump start is cut off the water supply in supercharging the function in water route; When water pump disconnected, earlier by sealing water port, place, center portion, seal membrane sealed the water port along the order from the center to the periphery to seal membrane gradually then under hydraulic pressure and spring action.Therefore, the sealing diaphragm structure of water pump all has buffering to hydraulic pressure when opening or closing effect, with present water pump packing diaphragm directly open fully or fully sealing compare, water pump is difficult for producing vibrations.
Described seal membrane ear end face is provided with hollow spring fastener, and resilient member one end is connected with hollow spring fastener, and the other end acts on the pump head inwall relative with the spring fastener.Prior art adopts tabular spring fastener, so seal membrane can move with the spring fastener under the spring force effect simultaneously; After adopting the structure of hollow spring fastener, seal membrane has only the part that contacts with the spring fastener to move under the spring force effect, and then move under the effect of hydraulic pressure at other positions.
Described seal membrane and water shutoff seat central axes, water shutoff seat center is provided with positioning hole, and the seal membrane center is fixed on the water shutoff seat by positioning hole by positioning screwn.
Described water port distributes radially along water shutoff seat center.
Described seal membrane and water shutoff seat central authorities surpass the residing part sealing of inlet coincide, and seal membrane is dish or curved surface shape.
To sum up; the beneficial effects of the utility model are: have the automatic water route function of cutting off of when shutdown; the water route control of pump thereby the realization supercharging is cut off the water supply; water route control is simplified; and the structure on the water shutoff seat all has buffering to hydraulic pressure when water pump opens or cuts out effect is fixed in the seal membrane center portion of water pump; with present water pump packing diaphragm directly open fully or fully sealing compare, water pump be difficult for to produce vibrations.
