Description

The end cap of an operational self-flowing well in underground groundwater intakes relates to the field of technical equipment necessary for the implementation of automated monitoring of the operating modes of water intakes using submersible, autonomous, programmable sensor recorders.

The wellhead is known [1, Utility Model Patent No. 175833, Self-Flowing Well Cap], including valve 1; stopper 2; conical tapering device 3; steel branch 4; ball valve 5; adapter for sampling water and connecting the pressure gauge 6; fastener 7; seal 8; bolted joint 9; threaded connection fastener 10; a welded joint connecting the fastener with a conical narrowing device 11; flange 12. The design of the tip is shown in figure 1 (general view) and in figure 1a (in section).

This tip has the following disadvantages:

- high labor intensity of manufacturing, since there is no mass production of the tip;

- when using in the top of the immersion sensor-recorder, there are difficulties with the frequent taking of his testimony, since the operator has to completely disconnect the conical narrowing device from the valve;

- the cap is intended for observant self-flowing wells and is not intended for use on production self-flowing wells operating in water supply networks.

Closest to the proposed device is the tip of a self-flowing well [2, Sealed tip wells. Release 3. Ogolovki self-flowing wells.]. It is produced in mass production. The cap contains two valves 1, a bolted connection 9, flanges 12, a bend made of steel pipes 13, a cover 14, a three-way valve 15 attached to the cover 14 by means of a threaded connection, a device for measuring the piezometric water level 16 attached to a three-way valve 15 s using a threaded connection, the cork drain valve 17 attached to the vertical section of the knee using a threaded connection. The design of the cap is shown in figure 2.

This tip has the following disadvantages:

- it is impossible to control the operation of an operating self-inflating well at air temperatures below minus 20 ° С;

- the tip is not intended for use of autonomous submersible sensors-recorders, allowing to automate the control of the well operation

- the connection of the cork drain valve to the vertical section of the knee using a threaded connection reduces the strength of the tip and causes technical difficulties during its operation.

The technical result of the utility model is to reduce the complexity of manufacturing and improve operating conditions.

The technical result is achieved by the fact that the tip is proposed for a production self-inflating well containing two valves connected to the knee by means of bolted joints, a cover connected to the knee by means of bolted connections, cork cock, a device for measuring the piezometric water level, characterized in that steel tee attached to the lid with a threaded connection, fastener, made in the form of a cylindrical stud attached to the tee with threaded connection, wherein the plug valve is attached to the tee by a threaded connection device for measuring piezometric water level is attached to the fastener using a bolted connection.

The utility model is illustrated by the drawings shown in figures 3 and 3a. FIG. 3 shows a drawing of a general view of the tip. The cap contains: two valves 1, connected to elbow 13 by means of bolted connections 9, cork drain valve 17, a device for measuring the piezometric level 16, steel tee 18 attached to the cover 14 by means of a threaded connection, fastener 7 attached to the tee 18 s using a threaded connection 10, while the cork valve 17 is attached to the tee 18 by means of a threaded connection, a device for measuring the piezometric water level 16 is attached to the fastener 7 by means of a bolted joint ezhnoy part 19.

The proposed utility model is illustrated by the drawings:

FIG. 1 - Analog. General view of the tip of a self-inflating well (patent for utility model No. 175833);

FIG. 1a - Analog. The section along the axis А-А of the tip of the self-flowing well (the patent for the useful model №175833);

FIG. 3 - Utility model. General form.

FIG. 3a - Utility model. Cut along axis aa.

The utility model is as follows:

The valves 1, installed at the wellhead and the knee 13, are closed, the cork drain valve 17 is opened to discharge water, the fastener 7 with an automated measuring device attached to it, intended for measuring the piezometric water level 16, is unscrewed from the tee 18 and removed. A temporary plug is screwed into the tee 18, the valves 1 are opened, the head is filled with water, the air is released through the open cork drain valve 17. Then the valve is closed and the water supply from the well to the consumers is resumed. The measuring device 16 is disconnected from the fastener 7. With the help of a laptop, the measurement results of the piezometric water level are taken. After that, the sensor-recorder is programmed to the required mode of measurement and registration of the groundwater level and is again attached to part 7. To install the measuring device 16 connected to the fastener 7 in the top of the well of the valve 1, the temporary plug is unscrewed from the tee 18 7 with a measuring device 16 attached to it, is screwed into the tee 18. Further, the operation of taking readings from the measuring device 16 is repeated as necessary.

The use of the proposed cap provides, in comparison with the currently used caps, the following advantages:

- ease of use head;

- reduction of labor costs for the manufacture of the tip.

The proposed device should be used for automated monitoring of the operation of self-flowing production wells of drinking groundwater intakes.
