Valve mounting well construction structure

Abstract

The utility model discloses a construction structure of a valve mounting well. The construction structure comprises a mounting well body; a bearing platform is fixed in the middle of the mounting well body, and a movable cover plate is mounted on the bearing platform in a contact manner; a pipeline penetrates through the mounting well body positioned at the upper part of the movable cover plate; a valve is mounted in the middle of the pipeline; and the mounting well body positioned at the lower part of the movable cover plate is communicated with a drainage pipe. When liquid leaks from the interior of the mounting well body and overflows from the well lid, the screw rod is rotated by using an internal hexagonal wrench to drive the movable cover plate to be upwards separated from the bearing platform to form an interval space, and the liquid is discharged to the drainage pipe from the interval space and then is discharged to the outside or a specified environment, so that the leaked liquid does not cover and shield a valve and a pipeline any more; therefore, the situation of the valve and the pipeline in the mounting well body can be observed, and the problem that the situation cannot be observed due to the fact that liquid can only overflow from the well lid at the top of the mounting well to cover and shield the valve and the pipeline is solved.

Description

Technical Field

[0001] The utility model relates to a valve installation well construction structure, belonging to the technical field of wellway construction. Background Art

[0002] When the middle part of the pipeline is controlled by a valve connection, an installation well is usually built to protect the valve in order to protect the safety of the valve.

[0003] The installation well of the existing valve is usually covered with a manhole cover on the top and a dense sealing plate structure at the bottom, see Chinese Patent Publication No. CN114838190B. When there is liquid leakage in the installation well, the liquid can only overflow and flow from the manhole cover at the top of the installation well. For deeper installation wells, the liquid covers the valves and pipes in the installation well, and there is a situation where the valves and pipes in the installation well cannot be observed. Utility Model Content

[0004] In order to solve the above technical problems, the utility model provides a valve installation well construction structure.

[0005] The utility model is realized through the following technical solutions.

[0006] The utility model provides a valve installation well construction structure, comprising:

[0007] Install the well body;

[0008] A support is fixed in the middle of the installation well body, and a movable cover plate is installed in contact with the support;

[0009] The installation well body located at the upper part of the movable cover plate is penetrated by a pipeline, and a valve is installed in the middle of the pipeline; the installation well body located at the lower part of the movable cover plate is connected to a drainage pipe.

[0010] The side wall of the installation well body is provided with two symmetrically distributed slide grooves, and sliding ears are fixed on both sides of the movable cover plate and extend into the slide grooves to slide up and down for cooperation, and force ears are symmetrically fixed on the tops of both sides of the installation well body corresponding to the slide grooves.

[0011] The sliding ear on one side of the movable cover plate is screwed with a screw rod through a thread pair, the screw rod has an inner hexagonal groove, and the screw rod is screwed with a force-bearing ear on one side of the installation well body through the thread pair.

[0012] The sliding ear on the other side of the movable cover plate can be slidably mounted with a guide slide bar, and the guide slide bar can slide and rotate through the force-bearing ear on the other side of the installation well body.

[0013] The top of the installation well body is provided with a step on which a well cover is installed, and the bottom of the installation well body is provided with a sealing bottom plate for sealing.

[0014] The installation well body is made of mortar concrete material; the well cover is made of plain iron or hard plastic.

[0015] An annular groove is provided in the support platform and an elastic rubber ring is installed therein, and the bottom surface of the movable cover plate is in elastic and tight contact with the elastic rubber ring in the support platform.

[0016] The beneficial effect of the utility model is that when liquid leaks inside the installation well and overflows from the manhole cover, an inner hexagonal wrench is used to rotate the screw rod to move the movable cover plate upward and disengage it from the base to form a separation space, and the liquid is discharged from the separation space to the drain pipe and then discharged to the outside world or a designated environment, so that the leaked liquid no longer covers the valves and pipes, so that the condition of the valves and pipes in the installation well can be observed, which solves the problem that the liquid can only overflow and flow from the manhole cover at the top of the installation well, covering the valves and pipes and making it impossible to observe the condition.

[0021] The technical solution of the utility model is further described below, but the scope of protection required is not limited to the description.

[0022] like Figures 1 to 3 shown.

[0023] A valve installation well construction structure of the present application includes:

[0024] During construction, an installation well body 1 is installed in the ground rock and soil, and the installation well body 1 is made of mortar concrete; a step is provided on the top of the installation well body 1 and a well cover 11 is installed thereon, and a sealing bottom plate 15 is provided at the bottom of the installation well body 1 for sealing, and the well cover 11 is made of plain iron or hard plastic.

[0025] A support 12 is integrally formed and fixed in the middle of the installation well body 1, and an annular groove is provided in the support 12 with an elastic rubber ring 2 installed. A movable cover plate 3 is installed on the support 12 in contact with the bottom surface of the movable cover plate 3 and is in elastic and tight contact with the elastic rubber ring 2 in the support 12.

[0026] The installation well 1 located above the movable cover 3 is penetrated by a pipeline 4, a valve 5 is installed in the middle of the pipeline 4, the valve 5 connects the pipeline 4 and controls the on-off of the pipeline 4; the installation well 1 located below the movable cover 3 is connected to a drainage pipe 41.

[0027] The side wall of the installation well body 1 is provided with two symmetrically distributed slide grooves 13, and sliding ears 31 are fixed on both sides of the movable cover plate 3, which extend into the slide grooves 13 and can slide up and down to cooperate, and force ears 14 are symmetrically fixed on the top of both sides of the installation well body 1 corresponding to the slide grooves 13; the sliding ear 31 on one side of the movable cover plate 3 is screwed with a screw rod 7 through a thread pair, and the screw rod 7 has a hexagonal groove for rotational driving with a hexagonal wrench, and the screw 7 is screwed on the force ear 14 on one side of the installation well body 1 through a thread pair; the sliding ear 31 on the other side of the movable cover plate 3 can be slidably installed with a guide slide rod 6, and the guide slide rod 6 can slide and rotate through the force ear 14 on the other side of the installation well body 1.

[0028] The screw 7 is screwed on the force-bearing ear 14 on one side of the installation well 1. At this time, the sliding ear 31 of the movable cover plate 3 plays a role in limiting the rotation in the slide groove 13 on the side wall of the installation well 1, so that the movable cover plate 3 can be rotated by the screw 7 and raised and lowered under the guidance of the guide slide rod 6. When liquid leaks from the installation well 1 and overflows from the manhole cover 11, the screw 7 is rotated with an Allen wrench to drive the movable cover plate 3 upward and disengage from the support 12 to form a space. The liquid is discharged from the space to the drain pipe 41 and then discharged to the outside world or a designated environment, so that the leaked liquid no longer covers the shielding valve 5 and the pipeline 4, so that the valve 5 and the pipeline 4 in the installation well 1 can be observed, solving the problem that the liquid can only overflow from the manhole cover at the top of the installation well and cover the shielding valve and the pipeline and cannot be observed.
