Abstract
The invention discloses a duplex pump body, which consists of first pump body and second pump body, wherein the first pump body and second pump body display an integral structure; the intake of first pump body connects the intake of second pump body and gathering a total intake; the outlet of first pump body connects the outlet of second pump body and gathering a total outlet; the convergence part forms a guide tab among total outlet, first pump body outlet and second pump body outlet; the unidirectional valve is set on the guide tab, which connects the guide tab to sway left and right between the first pump body outlet and the second pump body outlet. The invention designs two pump bodies as a whole and uses a total intake and outlet to control each intake and outlet by unidirectional valve in comparison with the present technique.
Description
Technical field:
The present invention relates to pump, relate in particular to duplex pump, particularly a kind of duplex pump.
Background technique:
In the prior art, daily life and commercial Application usually need to be equipped with simultaneously two pumps, a pump operation, another pump is standby, or two pumps moves simultaneously, in the prior art normally with the parallel connection of pumps setting of two platform independent, every pump all has independently a water intake and a water outlet, and the structure floor space of this two pumps independent design is big, the mounting cost costliness, the cost of production height uses very inconvenient.
Summary of the invention:
Technical problem of the prior art to be solved by this invention is: because in the prior art, daily life and commercial Application usually need to be equipped with simultaneously two pumps, a pump operation, another pump is standby, or two pumps moves simultaneously, normally with the parallel connection of pumps setting of two platform independent, every pump all has independently a water intake and a water outlet, and the structure floor space of this two pumps independent design is big, the mounting cost costliness, the cost of production height uses very inconvenient.
The present invention provides a kind of integrated two pump for the technological scheme that solves above-mentioned technical problem of the prior art and adopt, described this integrated two pump is made of first pump housing and second pump housing, wherein, described first pump housing and second pump housing mutually combine, the water intake of the water intake of described first pump housing and second pump housing all is connected with a total water inlet, the water outlet of the water outlet of described first pump housing and second pump housing all is connected with a total water outlet, is provided with an one-way valve between the water outlet of the water outlet of described first pump housing and second pump housing.
Further, described one-way valve is a tongues of fire one-way valve.
Further, the water outlet concourse of the water outlet of described first pump housing and second pump housing is provided with a tab, and described one-way valve is arranged on the described tab and with tab and flexibly connects.
Further, the central lines of described total water inlet and total water outlet.
The present invention and prior art contrast, and its effect is actively with tangible.The present invention is designed to an integral body with two pump housings, and a shared total water inlet and total water outlet, controls separately water outlet by one-way valve, so compact structure, volume is little, install easily, and cost of production is low.
Description of drawings:
Fig. 1 is the schematic representation of integrated two pump of the present invention when first pump housing works independently;
Fig. 2 is the schematic representation of integrated two pump of the present invention when second pump housing works independently;
The schematic representation that Fig. 3 is an integrated two pump of the present invention when first pump housing and second pump housing are worked simultaneously.
Embodiment:
As Fig. 1, Fig. 2 and shown in Figure 3, integrated two pump of the present invention is made of first pump housing 1 and second pump housing 2, wherein, described first pump housing 1 and second pump housing 2 mutually combine, the water intake 11 of described first pump housing 1 all is connected with a total water inlet 10 with the water intake 21 of second pump housing 2, the water outlet 12 of described first pump housing 1 all is connected with a total water outlet 20 with the water outlet 22 of second pump housing 2, is provided with an one-way valve 4 between the water outlet 22 of the water outlet 12 of described first pump housing 1 and second pump housing 2.
Further, described one-way valve 4 is a tongues of fire one-way valve.
Further, water outlet 22 concourses of the water outlet 12 of described first pump housing 1 and second pump housing 2 are provided with a tab 3, and described one-way valve 4 is arranged on the described tab 3 and with tab 3 and flexibly connects.One-way valve 4 flexibly connects with tab 3, can swing between the water outlet 22 of the water outlet 12 of first pump housing 1 and second pump housing 2;
Further, the central lines of described total water inlet 10 and total water outlet 20.
Working procedure of the present invention is as follows: when first pump worked independently, one-way valve 4 was flapped toward the water outlet 22 of second pump under the effect of water pressure of first pump, and closed this water outlet 22, and the water outlet 12 of first pump keeps unimpeded; In like manner, when second pump worked independently, one-way valve 4 was flapped toward the water outlet 12 of first pump under the effect of water pressure of second pump, and closed this water outlet 12, and the water outlet 22 of second pump keeps unimpeded; When two pumps were worked simultaneously, because the water pressure of two pumps balances each other, one-way valve 4 was in total water outlet 20 lengthwise positions, and the water outlet 12 of first pump and the water outlet 22 of second pump keep unimpeded simultaneously.
