Abstract
The utility model discloses a high-pressure sewer flushing vehicle winter drainage system. The high-pressure sewer flushing vehicle winter drainage system comprises a gas jar, a high-pressure water pump and a high-pressure water pipe. High-pressure gas can be filled into the gas jar. The gas jar and the high-pressure water pump, and the high-pressure water pump and the high-pressure water pipe are respectively connected through gas pipes. An outlet for discharging the high-pressure gas is formed in the high-pressure water pipe. A needle valve is arranged in the gas pipe connecting between the gas jar and the high-pressure water pump. The needle valve is used for controlling gas circulation between the gas jar and the high-pressure water pump. A water inlet of the high-pressure water pump is connected with a ball valve. A water outlet of the high-pressure water pump is connected with the high-pressure water pipe. The high-pressure gas enters the high-pressure water pipe and the high-pressure water pipe through the gas pipes, so that residual water in the high-pressure water pipe and the high-pressure water pipe can be discharged outside, and water can be prevented from freezing to damage the high-pressure water pipe and the high-pressure water pipe in a low temperature condition in winter. The high-pressure sewer flushing vehicle winter drainage system has the advantages that structural design is ingenious; residual water can be conveniently drained after the high-pressure sewer flushing vehicle winter drainage system is used, and the high-pressure water pump and the high-pressure water pipe are effectively protected.
Description
Technical field
The utility model relates to the cleaning Vehicle technical field, particularly a kind of high-pressure sewer flushing vehicle drainage system in winter.
Background technology
The high-pressure sewer flushing vehicle of existing market, after using end in the winter time, because winter, temperature was low, water residual in drainage system mesohigh water pump that it is inner and the high-pressure water pipe can't be got rid of, freezing easily under low-temperature condition causes damaging high-pressure hydraulic pump and high-pressure water pipe, makes the cleaning Vehicle can't operate as normal.
The utility model content
The utility model proposes a kind of high-pressure sewer flushing vehicle drainage system in winter; solved the problem of freezing and damaging easily when drainage system uses in the winter time in the prior art; this drainage system can be got rid of the water in residual very easily after use, effectively protect high-pressure hydraulic pump and high-pressure water pipe.
The technical solution of the utility model is achieved in that
High-pressure sewer flushing vehicle drainage system in winter, comprise gas jar, high-pressure hydraulic pump and the high-pressure water pipe that can charge into gases at high pressure, between described gas jar and the high-pressure hydraulic pump, be connected by tracheae respectively between described high-pressure hydraulic pump and the described high-pressure water pipe, described high-pressure water pipe is provided with the outlet of discharging gases at high pressure.
In the tracheae that is connected between described gas jar and the high-pressure hydraulic pump needle-valve is set, described needle-valve one end is connected with the tracheae that described gas jar links to each other, and the other end is connected with the described high-pressure hydraulic pump air inlet mouth of pipe.
Further, the water inlet of described high-pressure hydraulic pump connects ball valve, and its delivery port is connected with described high-pressure water pipe, by entering of described ball valve control high-pressure hydraulic pump water.
Described high-pressure water pipe is one encloses to spiral and is surrounded on the cylinder, constitutes layered laminate, and outward appearance is neat.
Operation principle of the present utility model is, at first close ball valve, open the needle-valve that is connected in the tracheae again, gases at high pressure in the gas jar enter high-pressure hydraulic pump and high-pressure water pipe by tracheae, thereby water residual in high-pressure hydraulic pump and the high-pressure water pipe is all discharged from the water under high pressure mouth of pipe under the effect of gases at high pressure, do not leave over.
The beneficial effects of the utility model are, structural design is ingenious, connect to make by body and form high pressure in the system, discharge the water that remains in high-pressure hydraulic pump and the high-pressure water pipe by gases at high pressure, effectively avoided water in the winter time low-temperature condition freeze down and damage high-pressure hydraulic pump and high-pressure water pipe.
Description of drawings
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, to do to introduce simply to the accompanying drawing of required use in embodiment or the description of the Prior Art below, apparently, accompanying drawing in describing below only is embodiment more of the present utility model, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain other accompanying drawing according to these accompanying drawings.
