Abstract
The utility model relates to an automatic pressure relief pipeline which comprises a manual ball valve, a screw pump and a pressure relief valve, wherein the manual ball valve is connected with the screw pump through a pipeline, and the pressure relief valve is connected to two ends of the screw pump through pipelines. Through setting up the relief valve and being connected with the both ends of screw pump, can replace the electrical connection between screw pump and the manual ball valve, reduce cost prevents to cause the misjudgement when electrical control connects badly. And during operation, the motor can be prevented from being repeatedly started and stopped under the condition of multiple times of pause operation, the effect of protecting the motor is achieved, and the loss of the motor caused by multiple times of starting and stopping of the motor is reduced.
Description
Technical Field
The utility model relates to the technical field of electromechanical equipment accessories, in particular to an automatic pressure relief pipeline.
Background
In pipeline operation, if the operation is to be suspended, the valve is closed to prevent the liquid in the pipeline from flowing out. However, if the valve is merely closed and the pump continues to operate, the pressure inside the pipeline is too high, and the pipeline and the fittings are easily damaged. At present, a pump and a valve in a pipeline are commonly electrically connected to achieve the effect that the pump and the valve can be opened and closed simultaneously, but when the electrical control connection is poor, misjudgment is easily caused, and the pipeline and accessories are still damaged.
SUMMERY OF THE UTILITY MODEL
The present invention is directed to an automatic pressure relief pipeline to solve the above problems encountered in the background art.
In order to achieve the purpose, the technical scheme of the utility model is as follows:
the utility model provides an automatic pressure release pipeline, includes manual ball valve, screw pump and relief valve, manual ball valve passes through the pipeline and is connected with the screw pump, the relief valve passes through the tube coupling at the both ends of screw pump, wherein the inlet channel of relief valve is connected between manual ball valve and screw pump, the outlet conduit of relief valve connects on the inlet channel of screw pump.
In the scheme, the water outlet pipeline of the screw pump is provided with the pressure gauge.
Compared with the prior art, the utility model has the beneficial effects that: through setting up the relief valve and being connected with the both ends of screw pump, can replace the electrical connection between screw pump and the manual ball valve, reduce cost prevents to cause the misjudgement when electrical control connects badly. And during operation, the motor can be prevented from being repeatedly started and stopped under the condition of multiple times of pause operation, the effect of protecting the motor is achieved, and the loss of the motor caused by multiple times of starting and stopping of the motor is reduced.
Drawings
The disclosure of the present invention is illustrated with reference to the accompanying drawings. It is to be understood that the drawings are designed solely for the purposes of illustration and not as a definition of the limits of the utility model. In the drawings, like reference numerals are used to refer to like parts. Wherein:
FIG. 1 is a schematic view of the overall structure of the present invention;
reference numbers in the figures: 1-a manual ball valve; 2-a screw pump; 3, a pressure relief valve; 4-pressure gauge.
Detailed Description
In order to make the technical means, the creation features, the achievement purposes and the effects of the utility model easy to understand, the utility model is further described in detail with reference to the attached drawings. These drawings are simplified schematic views illustrating only the basic structure of the present invention in a schematic manner, and thus show only the constitution to which the present invention relates.
According to the technical scheme of the utility model, a plurality of alternative structural modes and implementation modes can be provided by a person with ordinary skill in the art without changing the essential spirit of the utility model. Therefore, the following detailed description and the accompanying drawings are merely illustrative of the technical aspects of the present invention, and should not be construed as all of the present invention or as limitations or limitations on the technical aspects of the present invention.
The technical solution of the present invention is further described in detail with reference to the accompanying drawings and examples.
As shown in fig. 1, an automatic pressure relief pipeline, including manual ball valve 1, screw pump 2 and relief valve 3, manual ball valve 1 passes through the pipeline and is connected with screw pump 2, and relief valve 3 passes through the tube coupling at the both ends of screw pump 2, and wherein the inlet channel of relief valve 3 connects between manual ball valve 1 and screw pump 2, and the outlet conduit of relief valve 3 connects on the inlet tube way of screw pump 2.
When the screw pump works, the manual ball valve 1 is opened, and liquid in the pipeline flows out under the action of the screw pump 2. When the work is suspended, the manual ball valve 1 is closed, the screw pump 2 is still operated, liquid is conveyed into the output pipeline, and the pressure inside the pipeline is increased. Because the manual ball valve 1 is closed, liquid is shunted to the water inlet pipeline at the hydraulic valve 3, the pressure release valve 3 is opened under the action of pressure, and the liquid flows back to the conveying pipeline before the screw pump 2 again, so that the effects of reducing the internal pressure of the pipeline and protecting the pipeline are achieved. Therefore, the pressure inside the pipeline can be balanced and the pipeline and other accessories are protected by arranging the pressure release valve 3 to be connected with the two ends of the screw pump 2.
As a preferred scheme, a pressure gauge 4 is arranged on a water outlet pipeline of the screw pump 2, the pressure in the conveying pipeline can be known by observing the pressure gauge 4, and the partial pressure effect brought to the pipeline after the pressure release valve 3 is installed is determined.
Through setting up the both ends that relief valve 3 and screw pump 2 are connected, can replace the electrical connection between screw pump 2 and the manual ball valve 1, reduce cost prevents to cause the misjudgement when electrical control connects badly. And during operation, the motor can be prevented from being repeatedly started and stopped under the condition of multiple times of pause operation, the effect of protecting the motor is achieved, and the loss of the motor caused by multiple times of starting and stopping of the motor is reduced.
The above-mentioned embodiments, objects, technical solutions and advantages of the present invention are further described in detail, it should be understood that the above-mentioned embodiments are only specific embodiments of the present invention, and are not intended to limit the scope of the present invention, and any modifications, equivalent substitutions, improvements and the like made within the spirit and principle of the present invention should be included in the scope of the present invention.
