Abstract

The invention relates to a clip type check structure of a pump elbow. Primarily, it is provided with connected first and second pipelines. A gasket is disposed between the first and second pipelines and provided with a through hole at its middle position corresponding to an outlet of the first pipeline. Furthermore, an abutting projection rim is formed at the periphery of the through hole, and the second pipeline is arranged with an assembling hole at its lateral side. The clip type check structure is assembled and fixed to the assembling hole through a covering plate. The covering plate is provided with a handle and a pivoting ear at its outside and inside, respectively. The pivoting ear is provided with a valve covered an outside of the abutting projection rim of the gasket. Thereby the through hole is sealed. Accordingly, not only has the clip-type check structure better sealing performance and has the pump a better vacuum effect, but it is also not easy to be broken and damaged in the case of long-term use so as to prolong its service life. Even if failure or damage occurs, it can be easily disassembled and maintained, so as to increase the practicality and efficiency for the whole implementation.

Description

The clip-type backstop structure of the elbow of the pump

The present invention relates to a clip-type check structure for the elbow of a water pump, and especially refers to a clip-type check structure that not only has better sealing performance, but also makes the pump have a better vacuum effect, and it will work in long-term use. Under the circumstances, it is not easy to be broken and damaged, can prolong its service life, and can be easily disassembled and maintained even if there is a failure or damage problem, and it is more practical and functional in its overall implementation and use.

According to, the drainage design in the city is to discharge from high to low into the river or the ocean, and in order to avoid the flooding caused by the high water level of the river during the rainy season, it is common that there are dikes, bank protections and other counter-currents. Guidance is used to protect the city within the embankment from flooding. When planning the rainwater channel system in the city, it uses gravity flow to set up rainwater channels to discharge urban rainwater from the embankment to the outside of the embankment.

However, in low-lying areas, drainage will be affected by the water level outside the embankment and cannot be To let the water flow out of the dike by gravity flow, it is necessary to set up a pumping station. Large pumps are used in the pumping station to pump and discharge the water from low-lying areas to the outside of the dike. The structural design of this type of pump is very important. A water outlet pipe is connected to the water outlet, and a check valve is installed in the water outlet pipe to allow the pump to pump water out through the water outlet pipe. The check valve is set to prevent backflow of water and outside air from entering The situation happened.

Among them, please refer to the existing schematic diagram of the combined cross-sectional structure in Figure 5 and the existing partial three-dimensional exploded structure diagram of Figure 6. The check valve (5) is mainly provided with a first pipe (51) and a second pipe (52), and a gasket (53) and a valve disc (54) are respectively arranged between the first pipeline (51) and the second pipeline (52), and the valve disc (54) is made of soft material Manufactured, the valve disc (54) is fixed between the first pipeline (51) and the second pipeline (52) with a fixed end (541), and is integrally connected to one side of the fixed end (541) There is a movable end (542), so that the movable end (542) is closed outside the water outlet end of the first pipeline (51); ), the water flow will push the movable end (542) of the valve plate (54) to the direction of the second pipe (52), allowing the water flow to smoothly pass through the first pipe (51) and enter the second pipe Channel (52), and since the movable end (542) of the valve plate (54) is closed outside the outlet end of the first pipeline (51), the water flow in the second pipeline (52) is subject to the movable end The barrier of (542) cannot flow back into the first pipeline (51).

However, although the above-mentioned check valve can achieve the expected effect of restricting the flow of water, it is also found in the actual operation and use process that the check valve has the following shortcomings:

1. The valve plate is integrally connected with a movable end on one side of the fixed end, so that the fixed end is fixed between the first pipeline and the second pipeline, so that the movable end is driven by the water flow for a long time. During the process, the movable end is easily aging due to stress, resulting in poor sealing backstop effect, and even breakage, causing great inconvenience in use.

2. The valve disc system and the gasket are fixed between the first pipeline and the second pipeline together, so that when the valve disc is damaged or the air-tight check is affected by the clogging of mud and sand, it needs to be disassembled and replaced. The second pipe is disassembled and separated from the first pipe, and the first and second pipes have a certain volume and weight, and other larger machines are required in the disassembly process, which causes extremely troublesome and inconvenient maintenance.

3. The gasket and the valve plate are fixed between the first pipeline and the second pipeline, so that during the process of locking and fixing, the contact surface is very easy to be uneven, which may cause stress to concentrate on a specific position due to squeezing. As a result, the contact surface cannot be tightly sealed, and the check valve will have air-tight leakage, so that there is still room for improvement in the overall structural design.

The reason is that, in view of this, the inventor upholds many years of rich experience in design, development and actual production in the related industry, and then researches and improves the existing structure and deficiencies, and provides a clamp-type check structure for the elbow of the pump, in order to achieve a better The purpose of good practical value.
