RU189969U1 - The gate gate folding - Google Patents

Abstract

The utility model relates to hydraulic engineering, in particular, to hermetic shut-off devices used in self-flowing sewer chambers. The utility model, then the slide gate (or slide gate), is designed for installation in existing chambers to be reconstructed. The frame (frame) and the shield of the slide gate are made collapsible into component parts, the dimensions of which allow loading them into the chamber through a standard hatch in the ceiling. The final assembly of the slide gate is made during installation inside the chamber at the place of its installation. The folding design of the slide gate allows you to avoid work on disassembling the ceiling of existing chambers and their subsequent restoration, which significantly reduces labor, material costs and runtime.

Description

The utility model relates to hydraulic engineering, in particular, to hermetic shut-off devices used in self-flowing sewer chambers. The utility model, further a gate valve or gate, is intended for installation in existing chambers, when replacing valves with an expired service life or, if necessary, for installation in existing chambers where the channel overlap was not originally provided.

The prior art known gate valve, collapsible shield which consists of at least two longitudinal vertical sections, assembled together by moving and / or fixed detachable joints, used during preventive and repair work, the RF patent №17547 (class F16K 3/00, E02B 7/26), published 04/10/2001. The dimensions of the shield sections ensure their free passage through the neck of a standard round hatch in the ceiling of the chamber overlap and the subsequent assembly of the shield at the installation site.

From the description of the patent US 5797588A (Cl. F16K 3/00), published 08.25.1998 g, also known collapsible shield, designed for installation in open channels U-shaped.

From the description to the patent of the Russian Federation No. 32143 (Cl. E03C 1/262), published on 10.09.2003, a gate valve is known, intended to be installed in a frame from a previously dismantled gate, concreted in the channel walls.

From the description to the patent of the Russian Federation No. 100166 (Cl. F16K 3/02), published on December 10, 2010, there is also a known gate valve designed for installation in existing chambers, where the channel overlap was not originally provided or instead of damaged stop equipment.

The disadvantage of the first and second known solutions is the ability to install a shield only in an existing frame, to replace the previously used and similar in size. The first three variants of locking devices are installed in existing concreted frames, which, under the influence of aggressive environment and operational loads, can be as damaged as the shields to be replaced, which makes it difficult or make the installation of new shields impossible. These shut-off devices cannot be installed in chambers that were not previously equipped with shut-off valves, without additional work on the design, manufacture and installation of new gate frames.

Also the disadvantage of the third and fourth locking devices are their overall dimensions, which do not allow to move them into the chambers through the mouths of standard hatches. For their installation, it is necessary to disassemble the ceiling ceilings of the existing chambers, which is associated with the holding of multi-cost measures, both in opening and subsequent restoration of the ceilings and the adjacent terrain.

Installing the shield of the second locking device is possible only in the channels where the mating of the walls and the bottom of the channel is made along a radius that coincides with the radius of the junction of the sidewalls and the bottom of the shield, which also imposes a restriction on its use, and requires additional refinement of either the channel or the shield.

The technical result of the claimed utility model is the ability to install a locking device in existing chambers of sewer channels of any shape without dismantling the ceiling, which significantly reduces labor, material costs and time for work.

This result is achieved by the fact that the slide gate is made collapsible into its component parts, the dimensions of which allow loading them into sewers through standard hatches. The final assembly of the slide valve is performed in the sewer chamber during its installation.

The drawings show one of the options for the implementation of a collapsible sliding gate.

Figure 7 shows a local view of the body in the zone of the connection of its component parts.

Figure 8 shows the component parts of a smaller slide gate body.

Figure 9 shows the component parts of the larger slide gate body.

Sliding valve consists of body 1 and shield 2, which in the lower position blocks the flow of working medium.

The shield has the ability to be completely removed from the body, made collapsible and consists of at least two separate horizontal sections 3 and 4.

The number of horizontal sections depends on the size of the overlapped channel. Every two sections are interconnected by side plates 5 and 6 with rigid mounting bolts 7.

The body of the shutter consists of at least two components of poses. 8 and 9 in Figure 8 or pos. 13, 14 and 15 in Figure 9 and the two upper horizontal transverse beams 10 and 11. The components of the hull and the transverse beams are rigidly connected to each other by bolts with nuts 12. From the bottom or on the sides, the component parts are connected directly to each other, and from above they are connected by transverse beams 10 and 11. The number of component parts of the hull depends on the size of the channel to be closed, and all parts must pass freely through the neck of the standard hatch.

Sliding valve is fully assembled and checked at the place of manufacture, delivered assembled to the installation site. Installation of the slide gate in the chamber is as follows. The body and shield of the gate are separated and then disassembled into the parts of the detachable bolt joints provided by the design. Components with the help of lifting devices are loaded into the chamber through a hatch in the ceiling to the installation site, where slots for mounting the valve body are prepared in advance in the channel walls. Inside the chamber, the body parts are rigidly bolted together. The assembled case is installed vertically into the channel grooves and is concreted. Shield sections are rigidly interconnected by bolts and side plates. The assembled shield is installed in the case.

To regulate the flow of the medium, the opening or closing of the gate (raising and lowering of the shield) is carried out using lifting means (hoists, etc.) or manually.

Sliding valve, comprising a housing and a movable shield, characterized in that the housing is formed by at least two components and two upper transverse beams rigidly fastened together by detachable bolted joints. 2. Sliding valve according to Claim. 1, characterized in that the movable shield is formed by at least two horizontal sections rigidly fastened together with side plates with detachable bolted joints.
