Abstract
The utility model discloses an air exhaust plug for a liquid pump, and relates to liquid pumps. The air exhaust plug is provided with a cylindrical plug body, wherein a central ventilating hole is formed in the plug body; an end cover is arranged at the upper end of the plug body; an external screw thread is formed at the lower part of the plug body; an inclined ventilating hole for communicating the central ventilating hole and air is formed on the plug body at the lower side of the end cover; and the air communicating end of the inclined ventilating hole is lower than the central ventilating hole communicating end of the inclined ventilating hole. Rainwater during raining or washing water for cleaning a pump set is difficultly sputtered into a bearing cavity through the ventilating holes, so that the lubricating effect in the bearing cavity is good, and the service life of the pump is long. A filter net is arranged at the lower end of the central ventilating hole, so that returned air can be filtered, and impurities, such as dust and the like, can be prevented from entering the bearing cavity and further polluting lubricating oil.
Description
Technical field
The utility model relate to liquid pump, say it is a kind of liquid pump air relief cock in detail.
Background technique
We know, need be provided with bearing bore and air communication on the bearing support of liquid pump, be used for the air relief cock of the pressure in the equalizer bearing chamber.And the structure of present air relief cock is, is provided with cylindrical cock body, is provided with center roof vent in the cock body, and the cock body upper end is provided with end cap, and end cap downside cock body is provided with the level ventilation hole that center roof vent is connected with air, and the cock body bottom is provided with outside thread.During use, air relief cock is installed on the tapped through hole of bearing bore upper wall through the outside thread of bottom, makes bearing bore and air communication, the pressure in the equalizer bearing chamber.This air relief cock, the sparge water of rainwater or washery pump group in vent is splashed into bearing bore, causes Lubricants emulsification easily, influences the working life of pump.
Summary of the invention
The purpose of the utility model is the deficiency that solves above-mentioned existing technology, provides the sparge water of a kind of rainwater or washery pump group to be not easy in vent is splashed into bearing bore, the liquid pump air relief cock of the long service life of pump.
The technological scheme of the utility model is; A kind of liquid pump air relief cock is provided with cylindrical cock body, is provided with center roof vent in the cock body; The cock body upper end is provided with end cap; The cock body bottom is provided with outside thread, it is characterized in that end cap downside cock body is provided with the inclination vent that center roof vent is connected with air, and inclination vent and air communication end are lower than and are communicated with end with center roof vent.
The cock body of the center roof vent lower end in the utility model is provided with groove, is fixed with filter screen through pressure ring in the groove.
The beneficial effect of the utility model is; Because end cap downside cock body is provided with the inclination vent that center roof vent is connected with air; Tilt ventilation and air communication end is lower than and is communicated with end with center roof vent; The rainwater when raining or the sparge water of washery pump group are not easy in vent is splashed into bearing bore, the high lubricating effect in the bearing bore, the long service life of pump.Because the center roof vent lower end is provided with filter screen, can filter the air of backflow, prevent impurity entering bearing bore internal contamination lubricant oil such as dust.
Description of drawings
Fig. 1 is the structural representation of a kind of user mode of the utility model.
Embodiment
Liquid pump air relief cock as shown in Figure 1 is provided with cylindrical cock body 1, is provided with center roof vent 4 in the cock body 1; Cock body 1 upper end is provided with end cap 2; Cock body 1 bottom is provided with outside thread, and end cap 2 downside cock bodys 1 are provided with the inclination vent 3 that center roof vent 4 is connected with air, and inclination vent 3 and air communication end are lower than and are communicated with end with center roof vent; The cock body of center roof vent 4 lower ends is provided with groove, is fixed with filter screen 5 through pressure ring 6 in the groove.During use; The liquid pump air relief cock is installed on the bearing bore vent hole of bearing support 7; The rainwater when raining or the sparge water of washery pump group stopped by end cap, and the ventilation of tilting is lower than with center roof vent with the air communication end and is communicated with end, and water class impurity is not easy in vent is splashed into bearing bore; High lubricating effect in the bearing bore, the long service life of pump.Because the center roof vent lower end is provided with filter screen, can filter the air of backflow, prevent impurity entering bearing bore internal contamination lubricant oil such as dust.
