Detailed Description

Referring to fig. 1-2, in an embodiment of the present invention, an exhaust apparatus of a diaphragm pump includes a pump body (50) and an exhaust assembly (60), a water inlet (31) is disposed on the pump body (50), the water inlet (31) is communicated with a pressure relief hole (18), the pressure relief hole (18) is disposed in an exhaust cavity (20), a water outlet (16) is further disposed on one side of the pressure relief hole (18) of the exhaust cavity (20), a diversion trench (17) is disposed on the water outlet (16), the water outlet (16) is communicated with a water outlet (30), a step (19) is further disposed on the exhaust cavity (20), a first sealing rib (61) is disposed on the step (19), an exhaust diaphragm (15) is further disposed on the step (19), a first bump (14) and a second bump (62) are disposed on the exhaust diaphragm (15), an exhaust spring seat (13) is disposed on the first bump (14), and a spring (12) is arranged on the exhaust spring seat (13), and the exhaust cover (11) is pressed against the spring (12).

Preferably, be equipped with cavity (6) in exhaust lid (11), cavity (6) are equipped with the sealed muscle of second (5), the sealed muscle of second (5) outside is equipped with exhaust entry (2), exhaust exit (1) is connected in exhaust entry (2), exhaust entry (2) are cambered surface form (3), sealed muscle is higher than the cambered surface of exhaust entry (2).

Preferably, the spring (12) is inserted into the inner chamber (6) of the exhaust cover (11), the exhaust outlet (1) extends outwards, and the outer side of the exhaust outlet (1) is of a pagoda structure.

Preferably, a pressing ring (63) is further mounted on the cavity (6), the pressing ring (63) presses the exhaust diaphragm (15), the exhaust diaphragm (15) is embedded by the first sealing rib (61), the second bump (62) of the exhaust diaphragm (15) presses the inner bottom plane of the exhaust cavity (20) and seals the pressure relief hole (18) and presses the flow guide groove (17), an exhaust hole (66) is further formed in the exhaust diaphragm (15), and the exhaust hole (66) and the flow guide groove (17) form a passage.

The specific implementation mode is as follows: the motor drives the pump to work, the pump starts pumping water, at the moment, the pump contains a large amount of air, water is sucked from the water inlet and gushes into the water outlet, because the pump is connected with other equipment for supplying water, for example, when the water is supplied to the boiler, the boiler can generate a large amount of steam in the working process, the generated steam can generate pressure on the water outlet, the pressure in the pump is less than the pressure generated by the steam, so that the air can not be discharged from the water outlet, the water pushes the air in the pump to extrude the air to the water outlet hole, the water outlet hole is connected with the flow guide groove, at the moment, the second bump of the exhaust diaphragm presses the inner bottom plane of the exhaust cavity to seal the pressure relief hole and press the flow guide groove, the exhaust hole in the exhaust diaphragm and the flow guide groove form a passage, the air enters the flow guide groove and overflows to the exhaust hole from the passage, then overflows to the cavity of the exhaust cover from the exhaust hole, and the air continuously gushes into the exhaust inlet from the cavity and overflows from the exhaust outlet.

Further, after the whole exhaust of air, because of the effect of pressure in the pump, can make water overflow by the apopore and flow to the guiding gutter, at this moment, because the density of water is greater than the air, the air can't promote the exhaust diaphragm, and water can give exhaust diaphragm thrust, the exhaust diaphragm is upwards bloated after being promoted, exhaust diaphragm bloates the top and moves the exhaust spring holder, the spring of exhaust spring holder is extrudeed, at this moment, the exhaust diaphragm closely laminates with the sealed muscle of second, it is sealed with the cavity, make water not have from the cavity and flow to exhaust entry, at this moment, the motor drives the pump and lasts work, pressure in the pump lasts the increase, pressure when the delivery port is greater than the pressure that boiler steam produced, then water is carried to the boiler from the delivery port.

Further, the exhaust inlet is arc-surface-shaped and used for protecting the exhaust diaphragm, specifically, when the exhaust diaphragm bulges upwards, the arc surface can enable the exhaust diaphragm to bulge better without damaging the exhaust diaphragm, and air can enter the exhaust inlet better due to the arc-surface-shaped design; the sealing ribs are higher than the cambered surface of the exhaust inlet, and when the diaphragm bulges upwards and is attached to the second sealing ribs, the exhaust diaphragm blocks the exhaust inlet, so that water cannot flow into the exhaust inlet.

Further, when water can not overflow from the exhaust inlet, only can flow to the pressure relief hole, flow into the pump body by the pressure relief hole, from this circulation, thereby guaranteed to accomplish the back at the exhaust, water can not flow from the exhaust outlet, but flow back to the pump, guaranteed that water can all flow out the use from the delivery port, and simultaneously, the size in pressure relief hole, when having still played when the delivery port is stopped up, but water circular transport returns the water inlet, the biggest hydraulic size that the pump bore can change along with the size in pressure relief hole, the safety of pump and motor has been protected.

Further, when the pump stops working, the water in the pump partially flows to the water outlet and is conveyed to the boiler, the residual water returns to the water inlet due to the circulating flow, the exhaust diaphragm loses the thrust, the spring with elasticity rebounds to push the exhaust diaphragm back, the exhaust diaphragm is restored to the initial state, and meanwhile, the spring is also restored to the initial state.

To sum up the embodiment, only be the specific implementation way of the preferred embodiment of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art is familiar with the technical scope of the present invention.
