Description
Technical Field
The utility model belongs to steel pipe production facility field, in particular to no pressure release cooling water conveyor.
Background
In the welding process of steel pipe production, water cooling is needed, and a cooling water conveying device is important equipment for cooling water circulation. In the past, a water pump is generally directly communicated with a water lifting pipe, a water tap at the lower part of the water lifting pipe absorbs water and prevents pressure release, the water tap is generally poor in tightness, and when the cooling water conveying device is shut down for a long time, the water pump and the water lifting pipe are possibly emptied under the action of position difference, so that great trouble is brought to restart.
Disclosure of Invention
An object of the utility model is to overcome prior art's not enough, provide a leakproofness better, can effectively prevent the no pressure release cooling water conveyor of pressure release.
The utility model provides a its technical problem realize through following technical scheme:
the utility model provides a no pressure release cooling water conveyor which characterized in that: by the water lift portion, balanced pressure output portion constitutes, the water lift portion is connected in balanced pressure output portion lower part, the water lift portion is two sets of, and two sets of water lift portions are connected side by side in balanced pressure output portion below, by the water pump, the motor, prevent the pressure release seal pot, the lifting pipe, connect the water pipe, prevent that the pressure release valve constitutes, the water pump sets up in the cistern oral area and is connected with motor drive, the water inlet with prevent the pressure release seal pot, the lifting pipe communicates in proper order, the delivery port with be connected the water pipe, balanced pressure output portion communicates in proper order, prevent that the pressure release valve sets up on connecting the water pipe.
And, the pressure-release prevention sealing tank is provided with a water injection valve at the top and a sewage valve at the lower part.
The utility model discloses an advantage and beneficial effect do:
1. the non-pressure-release cooling water conveying device is provided with the pressure-release-preventing sealing tank, and the pressure release of the water pump during the shutdown can be effectively prevented.
2. The non-pressure-release cooling water conveying device is provided with the water injection valve and the sewage discharge valve on the pressure-release prevention sealing tank, and water injection and sewage discharge are convenient.
3. The non-pressure-release cooling water conveying device is provided with the pressure-release-preventing valve, and is good in sealing performance and simple and convenient to operate.
4. The non-pressure-release cooling water conveying device is scientific and reasonable in structural design, can effectively prevent the pressure release of the water pump during shutdown, has the advantages of convenience in water injection and sewage discharge, simplicity and convenience in sealing operation and the like, and is a high-innovativeness non-pressure-release cooling water conveying device.

Detailed Description
The present invention will be described in further detail with reference to specific examples, which are provided for illustrative purposes only, and are not intended to be limiting, and the scope of the present invention should not be limited thereby.
The pressure-relief-free cooling water conveying device consists of a water lifting part and a pressure-balancing output part, wherein the water lifting part is connected to the lower part of the pressure-balancing output part.
The balance pressure output part is a balance pressure output water tank 5.
The water lift portion is two sets of, and two sets of water lift portions are connected in balanced pressure output portion below side by side, by water pump 8, motor 9, prevent pressure release seal tank 3, lifting pipe 1, connect water pipe 6, prevent that pressure release valve 7 constitutes, the water pump sets up in the cistern oral area and is connected with motor drive, the water inlet with prevent that pressure release seal tank, lifting pipe communicate in proper order, the delivery port with connect water pipe, balanced pressure output portion communicate in proper order, prevent that pressure release valve sets up on connecting the water pipe. The top of the pressure-relief-preventing sealed tank is provided with a water injection valve 2, and the lower part of the pressure-relief-preventing sealed tank is provided with a sewage discharge valve 4.
The utility model discloses a theory of operation does:
after the water pump is shut down, the pressure relief prevention valve is closed, so that the water pump, the pressure relief prevention sealing tank and the water lifting pipe form a completely closed state, water in the water pump, the pressure relief prevention sealing tank and the water lifting pipe cannot leak even if cooling water in the water pump, the pressure relief prevention sealing tank and the water lifting pipe are in a potential difference state, and water does not need to be injected again for emptying when the water pump is restarted, so that time and labor are saved.
Although the embodiments of the present invention and the accompanying drawings are disclosed for illustrative purposes, those skilled in the art will appreciate that: various substitutions, changes and modifications are possible without departing from the spirit and scope of the present invention and the appended claims, and therefore, the scope of the present invention is not limited to the disclosure of the embodiments and the accompanying drawings.
