Explosion-proof portable pump for pumping liquid from a cavity in the extension column of the spindle of pipeline valves of main gas pipelines (TPA)

Abstract

This utility model relates to the operation of above-ground pipeline valves (PV) in main gas pipelines, specifically explosion-proof portable pumping devices for pumping liquids from process equipment cavities. The purpose of this utility model is to create a self-contained, explosion-proof device for efficiently pumping liquids from the PV spindle extension column cavity with the ability to reliably position the suction element in narrow vertical cavities. The technical result of this utility model is to ensure reliable removal of liquids from narrow PV spindle extension column cavities in explosive environments without permanent installation or external power supply.This technical result is achieved by an explosion-proof portable pump comprising an electric pump with suction and discharge pipelines, a battery, and a power button. The electric pump and battery are housed in an explosion-proof housing, while the explosion-proof button is mounted in the housing wall. The suction pipeline is a flexible silicone tube with weights at the end to ensure immersion in the liquid. The discharge pipeline is a drainage tube for removing the pumped liquid. This utility model enables autonomous and safe pumping of liquid from hard-to-reach, narrow cavities in injection molding machine spindle extension columns, preventing corrosion and freezing of the equipment, while ensuring reliable positioning of the suction element through the use of weights.

Description

[0001] The utility model relates to the field of operation of pipeline valves (PV) of above-ground design for main gas pipelines, in particular to explosion-proof portable pumping devices for pumping liquid from cavities of process equipment.

[0002] A portable pumping station (patent for utility model RU 117987 U1, published July 10, 2012) is known, comprising a housing, a drive including an electric motor and an associated battery mounted on the outer bottom of the housing, a hydraulic pump, a tank for working fluid, injection and drain hoses, and a switch (button) mounted in the side wall of the housing. This device is accepted as a prototype.

[0003] The disadvantages of the prototype are the lack of explosion protection, which makes it impossible to use it in explosive environments of gas transportation enterprises, as well as the lack of means for positioning the suction hose in narrow vertical cavities, such as the extension columns of the spindles of pipeline valves of main gas pipelines (hereinafter referred to as TPA).

[0004] The purpose of the utility model is to create an autonomous explosion-proof device for efficient pumping of liquid from the cavity of the injection molding machine spindle extension column with the ability to reliably position the suction element in narrow vertical cavities.

[0005] The technical result of the utility model is to ensure reliable removal of liquid from narrow cavities of injection molding machine spindle extension columns in explosive environments without stationary placement and external power supply.

[0006] The specified technical result is achieved in that in an explosion-proof portable pump for pumping liquid from a cavity in a column of a spindle extension of pipeline valves of main gas pipelines (TPA), containing an electric pump with a suction and pressure pipeline, a battery and a power button, according to the utility model, the electric pump and the battery are placed in an explosion-proof housing, the power button is made in an explosion-proof design, while the suction pipeline is made in the form of a flexible silicone tube with weights at the end to ensure immersion into the cavity of the column of the TPA spindle extension through a process hole, and the pressure pipeline is made in the form of a drainage tube for draining the pumped liquid.

[0007] The essence of the utility model is explained by a figure in which: an explosion-proof housing pos. 1, in which are mounted: an electric pump pos. 2, a storage battery pos. 3, an explosion-proof switch pos. 4, a suction pipeline pos. 5 with a length of 2 m and with weights pos. 6 at the end and a pressure pipeline pos. 7.

[0008] The utility model works as follows:

[0009] Before operation, charge the battery. A flexible silicone tube with weights is inserted into the cavity of the injection molding machine's spindle extension column through a process opening. The weights ensure that the end of the tube is immersed in the liquid, even in narrow vertical cavities. Pressing the button activates an electric pump powered by the battery; the liquid is drawn through the suction tube and discharged through the drain tube into a prepared container. An explosion-proof enclosure ensures safe operation in the explosive environment of gas transmission facilities.

[0010] This utility model allows for autonomous and safe pumping of liquid from hard-to-reach cavities of injection molding machine spindle extension columns, preventing corrosion and freezing of equipment, while ensuring reliable positioning of the suction element through the use of weights.

[0011] Thus, the technical result of the utility model is achieved, namely, ensuring reliable removal of liquid from narrow cavities of the injection molding machine spindle extension columns in explosive environments without stationary placement and external power supply.
