Abstract
Disclosed is a double linked pump, comprises a first pump body and a second pump body, wherein, the first pump body and the second pump body are an integration mechanism, the water inlet of the first pump body and the water inlet of the second pump body are communicated with each other and are collected into a main water inlet, and the water outlet of the first pump body and the water outlet of the second pump body are communicated with each other and are collected into a main water outlet; the middle of the main water outlet and the interconnecting point of the water outlet of the first pump body and the water outlet of the second pump body form a tongue on which a one-way valve is arranged, and the one-way valve is movably connected with the tongue, which can swing left and right between the water outlet of the first pump body and the water outlet of the second pump body. Compared with the prior art, because the two pump bodies are designed into an integration and share one main water inlet and main water outlet, and each water outlet of the two pump bodies are controlled through the one-way valve, the utility model has very compact design mechanism, small volume, easy installation and low producing cost.
Description
Technical field:
The utility model relates to pump, relates 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 in the utility model 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 utility model 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 utility model and prior art contrast, and its effect is actively with tangible.The utility model 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 utility model when first pump housing works independently;
Fig. 2 is the schematic representation of integrated two pump of the present utility model when second pump housing works independently;
The schematic representation that Fig. 3 is an integrated two pump of the present utility model 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 utility model 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 utility model 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.
