Description
Technical Field
The utility model belongs to the technical field of the water pump technique and specifically relates to an exhaust check valve of centrifugal pump.
Background
The centrifugal pump needs to discharge air in the pump body before working, generally injects water into the pump body through the water inlet pipe or the water outlet pipe to discharge air so as to discharge air in the pump body from the exhaust port of the pump body, but when the centrifugal pump is used in a high-pressure environment, the air pressure outside the pump body is large, so that the air in the pump is possibly difficult to discharge and even flows back into the pump body, and the problem needs to be solved.
Disclosure of Invention
The utility model provides an exhaust check valve of centrifugal pump can make the interior gas of pump smoothly discharge when the centrifugal pump is used for the high atmospheric pressure environment.
The utility model adopts the following technical scheme.
An exhaust check valve of a centrifugal pump, wherein an exhaust port communicated with an inner cavity of a pump body is arranged at the pump body of the centrifugal pump; an exhaust check valve for exhausting gas in the pump body is arranged at the exhaust port; the air inlet end of the exhaust check valve is communicated with the exhaust port; and an openable sealing cover is arranged at the air outlet end of the exhaust check valve.
The centrifugal pump enters water from a water outlet pipe or a water inlet pipe of the centrifugal pump to exhaust air when exhausting air; stop valves are arranged at the water outlet pipe and the water inlet pipe;
when the centrifugal pump exhausts, if water enters from the water inlet pipe and exhausts, the stop valve at the water inlet pipe is communicated to input high-pressure water; the stop valve at the water outlet pipe is closed;
when the centrifugal pump exhausts, if water enters from the water outlet pipe and exhausts, the stop valve at the water outlet pipe is conducted to input high-pressure water; the stop valve at the water inlet pipe is closed.
When the centrifugal pump exhausts, the sealing cover at the air outlet end of the exhaust check valve is opened; and when the centrifugal pump finishes exhausting, the sealing cover at the air outlet end of the exhaust check valve seals the air outlet end of the exhaust check valve.
An electric opening and closing device is arranged at the position of the closed cover; the electric opening and closing device can be controlled in a wireless remote control mode.
The centrifugal pump is used in a high-pressure environment.
The utility model discloses set up the exhaust check valve in centrifugal pump exhaust port department, its advantage lies in, when centrifugal pump work is under the high atmospheric pressure environment, even be less than the outer atmospheric pressure of pump in the water pressure short time in the pump, also can prevent that the outer high atmospheric pressure of pump is gaseous to pour into the pump in to can let the centrifugal pump exhaust smoothly in order to work under the high atmospheric pressure environment.
The utility model discloses all set up the stop valve in advancing, delivery port department, adopt the water under high pressure to fill the pump body when exhausting moreover, consequently can form high water pressure in the pump body and exhaust, overcome the influence of external high atmospheric pressure environment to centrifugal pump exhaust operation.
Drawings
The invention will be described in further detail with reference to the following drawings and detailed description:
FIG. 1 is a schematic diagram of the present invention;
in the figure: 1-an exhaust check valve; 2-an exhaust port; 6-sealing cover; 7-a pump body; 8-a stop valve; 9-a water inlet pipe; and 10-water outlet pipe.
Detailed Description
As shown in fig. 1, an exhaust check valve of a centrifugal pump, wherein an exhaust port 2 communicated with an inner cavity of a pump body is arranged at the pump body 7 of the centrifugal pump; an exhaust check valve 1 for exhausting gas in the pump body is arranged at the exhaust port; the air inlet end of the exhaust check valve is communicated with the exhaust port; and an openable sealing cover 6 is arranged at the air outlet end of the exhaust check valve.
The centrifugal pump feeds water from a water outlet pipe 10 or a water inlet pipe 9 of the centrifugal pump to exhaust when exhausting; stop valves 8 are arranged at the water outlet pipe and the water inlet pipe;
when the centrifugal pump exhausts, if water enters from the water inlet pipe and exhausts, the stop valve at the water inlet pipe is communicated to input high-pressure water; the stop valve at the water outlet pipe is closed;
when the centrifugal pump exhausts, if water enters from the water outlet pipe and exhausts, the stop valve at the water outlet pipe is conducted to input high-pressure water; the stop valve at the water inlet pipe is closed.
When the centrifugal pump exhausts, the sealing cover at the air outlet end of the exhaust check valve is opened; and when the centrifugal pump finishes exhausting, the sealing cover at the air outlet end of the exhaust check valve seals the air outlet end of the exhaust check valve.
An electric opening and closing device is arranged at the position of the closed cover; the electric opening and closing device can be controlled in a wireless remote control mode.
The centrifugal pump is used in a high-pressure environment.
Example (b):
before the centrifugal pump is started under the high-pressure production environment, the stop valve at the water outlet pipe is firstly turned off, then the stop valve at the water inlet pipe is opened, an operator does not need to enter the high-pressure production environment, the sealing cover at the air outlet end of the exhaust check valve is directly opened in a remote control mode, high-pressure water is input into the pump body through the water inlet pipe, gas in the pump body is pressed out of the pump body, then the stop valve at the water inlet pipe is closed, the sealing cover at the air outlet end of the exhaust check valve is controlled in a remote control mode, the air outlet end of the sealing cover is sealed to prevent the pump body from leaking water, and.
