Abstract
A combined reversing valve device comprises four reversing valves and a plurality of pipelines, wherein the four reversing valves are respectively a first reversing valve, a second reversing valve, a third reversing valve and a fourth reversing valve; has the advantages that the two filling pumps are mutually standby and the filling efficiency is improved.
Description
The technical field is as follows:
the utility model relates to a coal mining equipment technical field, the more specifically combination switching-over valve device that says so.
Background art:
in the waste rock paste filling technology, a filling pump is needed, and meanwhile, in order to ensure that the filling pump does not stop when the filling pump breaks down, 2 filling pumps are usually connected in parallel with 2 pipelines, so that the purpose of one filling pump for standby is achieved, only one filling pump can be used during production, the other filling pump is standby, the production efficiency is reduced, and the whole efficiency of the two filling pumps cannot be exerted.
The invention content is as follows:
in order to solve the problems, the utility model overcomes the defects of the prior art, and provides a combined reversing valve device with two filling pumps for mutual standby and improved filling efficiency.
The utility model provides a combination switching-over valve device, including four switching-over valves and a plurality of pipelines, four switching-over valves are first switching-over valve, second switching-over valve, third switching-over valve and fourth switching-over valve respectively, and first switching-over valve passes through the pipeline and links to each other with third switching-over valve and fourth switching-over valve respectively, and the second switching-over valve passes through the pipeline and links to each other with third switching-over valve and fourth switching-over valve respectively.
Furthermore, the device also comprises two filling pumps which are respectively communicated with the first reversing valve and the second reversing valve.
Further, the reversing valve comprises one inlet and two switchable outlets.
The utility model has the advantages that:
the utility model provides a combination switching-over valve device has two filling pumps advantage reserve each other, that improve packing efficiency.
The two filling pumps are used simultaneously, the effect of one filling pump for standby use is achieved, and the production efficiency is improved.
Description of the drawings:
FIG. 1 is a schematic structural diagram of the present invention;
in the drawings: 1. the system comprises a first reversing valve, a second reversing valve, a third reversing valve, a fourth reversing valve, a first pipeline, a second pipeline and a fourth reversing valve, wherein the first reversing valve 2, the second reversing valve 3, the third reversing valve 4, the fourth reversing valve 5, the first pipeline and the second pipeline.
The specific implementation mode is as follows:
in order to make the purpose, technical solution and advantages of the present invention clearer, the following will combine the attached figure 1 of the present invention to perform more detailed description of the present invention.
The utility model provides a combined reversing valve device, which comprises four reversing valves and a plurality of pipelines, wherein the four reversing valves are a first reversing valve 1, a second reversing valve 2, a third reversing valve 3 and a fourth reversing valve 4 respectively, the first reversing valve 1 is connected with the third reversing valve 3 and the fourth reversing valve 4 through the pipelines respectively, and the second reversing valve 2 is connected with the third reversing valve 3 and the fourth reversing valve 4 through the pipelines respectively; the device also comprises two filling pumps which are respectively communicated with the first reversing valve 1 and the second reversing valve 2; the reversing valve comprises one inlet and two switchable outlets.
The utility model discloses a one of them embodiment as follows:
the four reversing valves are respectively a first reversing valve 1, a second reversing valve 2, a third reversing valve 3 and a fourth reversing valve 4, each reversing valve comprises an inlet and two switchable outlets, two filling pumps are respectively communicated with the inlets of the first reversing valve 1 and the second reversing valve 2, the outlet of the first reversing valve 1 is respectively connected with the inlets of the third reversing valve 3 and the fourth reversing valve 4 through pipelines, and the outlet of the second reversing valve 2 is respectively connected with the inlets of the third reversing valve 3 and the fourth reversing valve 4 through pipelines.
The first reversing valve 1 is communicated with the fourth reversing valve 4 through a first pipeline 5, and the second reversing valve 2 is communicated with the third reversing valve 3 through a second pipeline 6.
In the actual use process, the first reversing valve 1 and the third reversing valve 3 are conducted, the second reversing valve 2 and the fourth reversing valve 4 are conducted, and the two lines can run simultaneously;
when the first filling pump breaks down, the second reversing valve 2 and the third reversing valve 3 can be communicated by adjusting the second reversing valve 2, and when the second filling pump breaks down, the first reversing valve 1 and the fourth reversing valve 4 can be communicated by adjusting the first reversing valve 1, so that two paths can be ensured not to be disconnected.
Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
