Detailed Description
The embodiments of the present invention will be described in detail below, examples of which are illustrated in the accompanying drawings, and the embodiments described below by referring to the drawings are exemplary and intended to explain the present invention so that the technical solutions of the present invention can be more easily understood and grasped, and cannot be construed as limiting the present invention.
Example (b):
an internal circulation water pump device is shown in fig. 1, and the design of the internal circulation refers to: when the common water pump is used, the water tank and the supply pipeline are connected, water in the water tank is pumped out and supplied to other water pipes for output, and at the moment, a path is supplied for water. On the basis of the water supply path, the scheme designs a loop returning to the water tank or the water inlet interface from the water supply output port. The purpose of this circuit design is to be able to partially recover the excess water quantity. The arrows in the figure indicate the direction of the water flow.
The concrete structure comprises a water pump body 1, a water inlet pipe 2 connected to the water pump body 1 and a water outlet pipe 3. Be provided with first governing valve 4 on the water pump main part 1, be provided with second governing valve 5 on outlet pipe 3, through bypass pipeline 6 intercommunication between second governing valve 5 and the inlet tube 2 way, second governing valve 5 is used for adjusting bypass pipeline 6's pressure release size. First governing valve 4 on the water pump main part 1 mainly is used for adjusting the supply water pressure of water pump main part 1 self, can set up water pump water pressure output size through this first governing valve 4, in an example, can be 50 kilograms with water pump main part 1 water pressure output adjustment, if the water pressure that pipeline or equipment that outlet pipe 3 is connected needs is 40 kilograms, then unnecessary water pressure need set up the relief valve on outlet pipe 3 and discharge, the pressure release, thereby protect the motor of water pump main part 1, otherwise break down easily. Therefore, the pressure can be released through the second regulating valve 5, and in the pressure releasing process, the water quantity and the water pressure are discharged to the water inlet pipe 2 or the water tank and can be reused for the water pump main body 1.
In order to improve assembly efficiency and maintain the convenient degree of use, the connection structure of this scheme is as follows: be equipped with pump case connecting seat 7 on the water pump main part 1, install inlet tube 2 on the pump case connecting seat 7, three-way pipe 8 is installed to the one end of inlet tube 2, connects bypass pipeline 6 through first return bend 9 on the three-way pipe 8, and bypass pipeline 6's the other end passes through on the second return bend 10 connects second governing valve 5. Through the design of vertical bypass pipeline 6, bypass pipeline 6 is transparent material, can more audio-visually see the dynamic effect of the water of backward flow. So as to facilitate later maintenance and service.
In order to improve the monitoring performance of the working process, the water outlet end of the second regulating valve 5 is connected with a ball valve switch 11, and the ball valve switch 11 is connected with a pressure gauge 12. Thereby effectively knowing the water outlet pressure and controlling the water outlet switch.
The water pump body 1 is also provided with a water pressure switch overvoltage protector 13. The hydraulic switch overvoltage protector 13 is an existing component, and automatically cuts off the power to stop the motor of the water pump body 1 when the output pressure of the water pump is not operated properly, so that the water pump body 1 is protected.
Of course, the above is only a typical example of the present invention, and besides, the present invention can also have other various specific embodiments, and all technical solutions adopting equivalent replacement or equivalent transformation are all within the scope of the present invention as claimed.
