Description
Technical Field
The utility model relates to a force (forcing) pump field especially relates to a check valve failure detection device.
Background
The stop valve is installed at the inlet of the pressurizing pump of the conventional secondary water supply equipment, the stop valve is installed at the outlet, if the function of the check valve fails during the work, the water hammer effect generated by the system can cause great damage to the equipment and the pipe network thereof, if the function cannot be found in time, great loss can be brought to users, and the paralysis of the whole equipment can be caused due to the damage of a small part.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a check valve detection device that became invalid solves the secondary water supply in, leaks a series of problems that the equipment water supply pressure that leads to is not enough, pipe network water hammer harm equipment in the check valve.
In order to realize the purpose, the technical scheme of the utility model is that:
the utility model provides a check valve failure detection device, its characterized in that, includes the import stop valve, the import stop valve passes through the pipeline and is connected with electric valve's input, electric valve's output passes through the pipeline and is connected with the input of water pump, the pipeline between electric valve output and the water pump input is equipped with pressure sensor, the output of water pump passes through the pipeline and is connected with the input of check valve, the output of check valve is equipped with water pump outlet stop valve.
The utility model has the advantages that: install electric valve and pressure sensor behind water pump import stop valve, detect equipment check valve control when stopping the pump, in time discover and solve the problem, reduce user's loss and maintenance cost, extension equipment and life.

Detailed Description
The technical solution of the present invention will be described clearly and completely with reference to the accompanying drawings, and obviously, the described embodiments are some, but not all embodiments of the present invention. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
The utility model discloses a check valve failure detection device, as shown in figure 1, including import stop valve 1, import stop valve 1 passes through the pipeline and is connected with electric valve 2's input, electric valve 2's output passes through the pipeline and is connected with water pump 4's input, the pipeline between 2 outputs of electric valve and the 4 inputs of water pump is equipped with pressure sensor 3, the output of water pump 4 passes through the pipeline and is connected with check valve 5's input, check valve 5's output is equipped with 4 export stop valves 6 of water pump.
As shown in figure 1, an electric valve 2 and a pressure sensor 3 are installed behind an inlet stop valve 1 of a water pump 4, when the water pump 4 works normally, the numerical value of the pressure sensor 3 is the pipe network pressure at the inlet end of the water pump 4, and after the water pump 4 stops, the electric valve 2 is closed.
If the pressure sensor 3 shows a large fluctuation in pressure and finally the steady pressure coincides with the outlet pressure, the non-return valve 5 fails and needs to be replaced.
As shown in fig. 2 and 3, the complete sets of conventional secondary water supply increases in every pump import the utility model discloses an electric valve 2 and pressure sensor 3 increase control module simultaneously in the switch board, make 4 reserve when stopping of water pump at every turn, close electric valve 2, detect pressure sensor 3's numerical value, if import and export pressure sensor 3 detects the unanimous change by a wide margin of pressure or import pressure sensor 3, then 5 troubles of switch board pilot lamp warning display check valve.
Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit the same; although the present invention has been described in detail with reference to the foregoing embodiments, it should be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; such modifications and substitutions do not depart from the spirit and scope of the present invention.
