RU159851U1 - HEAD FOR EMERGENCY OBSERVED SELF-WATERING WELL - Google Patents

Abstract

A head for an emergency observing self-flowing well of fresh groundwater deposits, containing a flange plug with a hole in the upper part of which is installed a vertical steel pipe with an external thread, a steel cover with an internal thread mounted on the pipe, a steel outlet connected to the cover, a ball valve connected with a tap, an adapter for sampling water and connecting a pressure gauge and a rubber seal, characterized in that it is equipped with a body of a removable coupling and a pressure sleeve, connected between themselves with four tightening bolts, and a stuffing box seal located between the body of the removable sleeve and the casing, with the possibility of sealing by tightening the bolts of the removable sleeve and the pressure sleeve, while the body of the removable sleeve is connected to the flange plug using a bolt connection, and between the body of the removable sleeve and a rubber seal is placed on the flange plug.

Description

The head for the emergency observing self-flowing well of fresh underground water deposits belongs to the field of technical means necessary to ensure the installation of the head during liquidation of the spill from the emergency well onto a casing not equipped with a connecting flange.

Known head of the well [1, Utility Model Patent No. 133189, head of the observation self-flowing well]. The design of the head is shown in figure 1. The head includes: gate valve 1; conical narrowing device 2; vertical pipe 3; steel branch 4; ball valve 5; adapter for sampling water and connecting a pressure gauge 6; stopper 7; flywheel 8.

This heading has the following disadvantages:

- high cost of the valve,

- the lack of installation on the casing of the well, not equipped with a connecting flange.

Closest to the proposed device is the head of the observation well with a variable static level [2, Patent for utility model No. 139322, head of the observation well with a variable static level]. The design of the head is shown in figure 2. The head includes: a flange plug with a hole 9; vertical steel pipe with external thread 10; steel cover with internal thread 11; steel branch 4; ball valve 5; adapter for sampling water and connecting a pressure gauge 6; tight connection of the pipe 10 with the cover 11 is carried out using a threaded connection 12 and the gasket 13.

This heading has the following disadvantage:

- the lack of installation on the casing of the well is not equipped with a connecting flange.

The technical result of the proposed head is the installation of the head to eliminate the spout from the emergency well, on the casing, not equipped with a connecting flange.

The technical result is achieved by the fact that the proposed head for an emergency observing self-flowing well of fresh underground water deposits containing a flange plug with a hole 9, in the upper part of which there is a vertical steel pipe with an external thread 10, a steel cover with an internal thread 11 installed on the pipe, a steel tap 4, connected to the cover, a ball valve 5 connected to the outlet, an adapter for sampling water and connecting a pressure gauge 6 and a rubber seal 13, characterized in that equipped with a body of a removable sleeve 14 and a pressure sleeve 17, interconnected by four tightening bolts 15, and an oil seal 16, located between the body of the removable sleeve and the casing, with the possibility of sealing by tightening the bolts of the removable sleeve and the pressure nut, while the body of the removable sleeve connected to the flange plug using a bolt connection 12, and between the housing of the removable coupling and the flange plug is placed a rubber seal 13.

The design of the proposed tip in the context is shown in figure 3. The tip contains: a flange plug with a hole 9, in the upper part of which is installed a vertical steel pipe with an external thread 10, a steel cover with an internal thread 11 mounted on the pipe, a steel outlet 4 connected to the cover , a ball valve 5 connected to the outlet, an adapter for sampling water and connecting a pressure gauge 6 and a rubber seal 13, characterized in that it is provided with a body of a removable sleeve 14 and a pressure sleeve 17, interconnected by four with two tightening bolts 15 and an stuffing box seal 16 located between the body of the removable sleeve and the casing, with the possibility of sealing by tightening the bolts of the removable sleeve and the pressure nut, while the body of the removable sleeve is connected to the flange plug using a bolt connection 12, and between the body a removable coupling and a flange plug placed rubber seal 13.

Installation of the head is as follows:

On the casing of the observation well, not equipped with a connecting flange, a push sleeve 17 is inserted, on the upper part of the casing of the emergency well the stuffing box 16 is wound, the housing of the removable coupling 14, having a diameter larger than the diameter of the casing by one size, fits onto the casing until the upper contact coupling flange with upper section of casing. A head for an observation well with a variable static level is attached to the upper flange of the body of the removable sleeve 14, providing water drainage. The pressure sleeve 17 is inserted from the bottom up into the gap between the casing of the well and the body of the removable sleeve, then with the tightening bolts 15, the pressure nut seals the stuffing box, ensuring tightness.

A general view of the tip is shown in figure 4.

The use of the proposed tip provides, in comparison with the heads currently used, the installation of the tip to eliminate the spout from the emergency well, on the casing, not equipped with a connecting flange.

The proposed device is advisable to use in the elimination of spills from emergency observing self-flowing wells not equipped with a connecting flange and the subsequent provision of hydrogeological monitoring.
