Abstract
Disclosed is a multifunctional screw plug composed of a lower screw plug (1) and an upper screw plug (2). The multifunctional screw plug is characterized in that two perpendicular channels communicated with each other are arranged inside the lower screw plug, the upper screw plug is in a threaded connection with the lower screw plug, the bottom of the upper screw plug is in a taper shape and can block the vertical channels in the lower screw plug when the upper screw plug is rotated to a certain extent. The multifunctional screw plug has the advantage of being capable of achieving gas discharge inside a water pump cavity.
Description
Technical field
The present invention relates to a kind of multi-functional air bleeder screw plug.
Background technique
Water pump is the machinery of carrying liquid or making the liquid supercharging.Necessaryly in the use of water pump to inject liquid.Because water pump seals, portion inevitably exists air or other gas within it.Gas can not be discharged and overstock in inside cavity when liquid injects, and this can influence the proper functioning of water pump, is the problem that needs solution.
Summary of the invention
The objective of the invention is to above problem, propose a kind of simple in structure and can realize air bleeder screw plug the discharging of pump chamber internal gas.In order to achieve the above object, design proposal of the present invention is following:
Air bleeder screw plug mainly comprises plug screw and two parts of last plug screw down.Be primarily characterized in that down that there are two vertical each other and be communicated with passages plug screw inside; Last plug screw and following plug screw are by being threaded, and last plug screw bottom is tapered, can be with descending passage vertical in the plug screw to block when rotating to a certain degree.In use, following plug screw is fixed on the top of pump chamber, and with its internal communication; Leave a fixed gap between last plug screw and the following plug screw.Then, beginning water filling in the water pump, gas can gather the top of cavity gradually along with the injection of current like this, and is discharged into the outside through air bleeder screw plug.When from air bleeder screw plug, flowing out water, will go up plug screw and tighten, make it will descend plug screw to block, so just cavity has been sealed; And the gas of inside cavity has also discharged and has finished.
The invention has the beneficial effects as follows the discharging that can realize the pump chamber internal gas.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the present invention is further described:
Fig. 1 is that structure of the present invention is always schemed.
As shown in the figure, among the figure: 1. descend plug screw, 2. go up plug screw.
Embodiment
Have shown in Figure 1ly, in use, following plug screw be fixed on the top of pump chamber, and with its internal communication; Leave a fixed gap between last plug screw and the following plug screw.Then, beginning water filling in the water pump, gas can gather the top of cavity gradually along with the injection of current like this, and is discharged into the outside through air bleeder screw plug.When from air bleeder screw plug, flowing out water, will go up plug screw and tighten, make it will descend plug screw to block, so just cavity has been sealed; And the gas of inside cavity has also discharged and has finished.
