Description

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

This creation is about a clip-type check structure for the elbow of a water pump, especially referring to a type that not only makes the clip-type check structure have better sealing properties, but also makes the pump have a better vacuum effect, and it will operate for a long time. Bottom, it is not easy to be broken and damaged, can prolong its service life, and even if there is a failure or damage problem, it can also be easily disassembled and maintained, so that it can be used in the overall implementation of the pump elbow card with more practical features Innovative designer of turn-type check structure.

According to the reason, 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 to have dikes, bank protections and other counter-currents. Guidance is carried out to protect the city within the embankment from flooding. When planning the rainwater channel system in the city, gravity flow is used to set up rainwater channels to discharge urban rainwater from the embankment to the outside of the embankment.

However, in low-lying areas, the drainage will be affected by the water level outside the embankment, and it is impossible to let the water flow out of the embankment by gravity flow. Therefore, it is necessary to set up a pumping station and use large pumps in the pumping station to reduce the water flow in the low-lying area. Pumping and discharge to the outside of the embankment; and in the structural design of this type of pumping machine, an outlet pipe is connected to the outlet end, and a check valve is installed in the outlet pipe to allow the pump to pump water out through the outlet pipe. And with the setting of the check valve, the water backflow and the ingress of outside air are prevented.

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 The valve plate (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); so that when water flows through the first pipeline (51), it wants to enter the second pipeline (52) ), 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 direction of water flow, it has also been discovered during its actual operation and use that the check valve has the following disadvantages:

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. The 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 together between the first pipeline and the second pipeline, so that when the valve disc is damaged or the air-tight check is affected by the clogging of sediment, 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 relatively large machines are needed in the disassembly process, which leads to 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, causing stress to concentrate on a specific position due to extrusion. As a result, the contact surface cannot be tightly sealed, and the check valve may 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 creators have years of rich experience in design and development and actual production in the related industry, researching and improving the existing deficiencies, and providing a clamp-type check structure for the elbow of the pump in order to achieve better practical value The purpose of sex.
