Description

A safe diversion and interception device for municipal pipe network

technical field

The utility model relates to the technical field of rainwater diversion treatment equipment, in particular to a safety diversion and interception device for municipal pipe networks.

Background technique

Water is the most precious resource for human beings, but due to human waste and environmental pollution, clean water resources are decreasing day by day. With the rapid development of society and economy, urban processes are accelerating, water resources are deteriorating, groundwater levels are declining, and urban water use Difficult problems are also becoming more and more serious. The country spends huge sums of money on the South-to-North Water Diversion Project, but it can only meet the water problem in some areas, and cannot fundamentally solve the problem of water shortage. In addition, urbanization has replaced the original vegetation and soil with impermeable ground. , leading to a large amount of rainwater loss and destroying the natural ecological and hydrological environment.

As a clean water source, rainwater plays an important role in the environment and water resource utilization, and has far-reaching significance to our living environment and water ecology. At present, more and more countries are beginning to pay attention to collecting clean rainwater. Rainwater collection usually uses roofs, ground roads, green spaces, natural hillsides, etc. The initial rainwater is mixed with a lot of pollutants, sediment and impurities. Therefore, the initial rainwater should be discarded. Collect the clean rainwater in the middle and late stage, and filter and remove the impurities in the rainwater to ensure the normal operation of the water storage system in the later stage and ensure the safety of drainage. The clean rainwater after treatment, evaporation and filtration can fully meet the standard of drinking water.

Traditional rainwater collection methods include various combinations of initial rainwater abandonment devices, interception wells, diversion wells, initial rainwater filtration, and grit chambers. When the treatment process is operated under the condition of high sludge load, expansion will occur, which makes it difficult to separate the sludge, resulting in the system not operating normally, the effluent is not up to standard, and the treatment is difficult. Moreover, the rainwater collection system in the prior art needs to build a new biochemical sedimentation tank, which leads to a large floor area and civil construction investment, and there are many disadvantages such as bloated equipment and large volume, which is not conducive to the development of rainwater resource utilization.

Contents of the invention

The purpose of this utility model is to provide a safe diversion and interception device for municipal pipe networks to solve the problems raised in the above-mentioned background technology.

In order to achieve the above object, the utility model provides the following technical solutions:

A safety diversion and interception device for municipal pipe networks, comprising a valve body, the valve body is a cylindrical tank structure, the top of the valve body is provided with an inspection port, and the left and right sides of the bottom of the valve body are respectively provided with water inlets and the water outlet, the bottom of the valve body is provided with a basket, and the inner side of the water outlet in the valve body is provided with a filter screen, which is inclined to the right. The end is connected with the top on the right side of the basket, the water inlet and the water outlet are arranged in the shape of pipe joints, and an overflow port is arranged on the side wall of the upper part of the valve body.

As a further solution of the utility model: the inspection port is covered with a protective cover, and the top of the inspection port is provided with a socket.

Detailed ways

The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. example. Based on the embodiments of the present utility model, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

Please refer to Figures 1 to 2. In the embodiment of the present utility model, a safety diversion and interception device for municipal pipe network includes a valve body 1, the valve body 1 is a cylindrical tank structure, and the top of the valve body 1 is set There is an inspection port 2, a protective cover is set on the inspection port 2, and a socket is provided on the top of the inspection port 2, which is convenient for plugging and connecting the protective cover. The left and right sides of the bottom of the valve body 1 are respectively provided with a water inlet 7 and a water outlet 8, The bottom of the valve body 1 is provided with a basket 6, the inside of the water outlet 4 in the valve body 1 is provided with a filter 5, the filter 5 is inclined to the right, and the top of the filter 5 is fixed on the valve body 1 on the upper side of the water outlet 4 On the inner wall, the bottom end of the filter screen 5 is connected to the top right side of the basket 6, so that the garbage retained on the filter screen 5 can enter the basket 6, the water inlet 7 and the water outlet 4 are arranged in a pipe-type interface shape, and the upper side of the valve body 1 An overflow port 3 is arranged on the wall, and the filter screen 5 is arranged in an arc-shaped groove shape.

The working principle of the utility model is: the utility model provides a safe diversion and interception device for municipal pipe network, with a novel structure; rainwater enters the diversion and interception device through the water inlet, and flows through the filter net to the downstream rainwater collection pipe network , impurities and sediment in the rainwater are intercepted by the filter and fall into the basket, and the basket can be cleaned regularly; when the rainwater in the collection pipe network is full, the water level in the diversion interception device rises, and the rainwater flows from the overflow to the downstream rainwater pipe network; Regularly open the inspection port and lift the basket out to clean up the sundries in the basket.
