Detailed Description

The following examples illustrate the utility model, but the utility model is not limited to these examples. Modifications and equivalents of some of the technical features of the specific embodiments of the present utility model may be made without departing from the spirit of the present utility model, and they are all included in the scope of the claimed utility model.

Example 1

Referring to fig. 1 to 3, the present embodiment provides a condensed water collecting device applied to a gas heating water boiler, comprising a housing assembly 1 and a valve assembly 2, wherein the housing assembly 1 has a water collecting chamber 101, a valve chamber 102, a water passing hole 113, a water inlet 121 communicating with the water collecting chamber 101, and a water outlet 131 communicating with the valve chamber 102, the water collecting chamber 101 is used for collecting condensed water flowing in from the water collecting port 121, the valve chamber 102 is located below the water collecting chamber, and the valve chamber 102 communicates with the water collecting chamber 101 through the water passing hole 113.

The valve component 2 can be arranged in the valve chamber 102 in a vertically movable manner and is used for opening or closing the water through hole 113, the valve component 2 is provided with a collecting tank 211 with an open top, and the collecting tank 211 is positioned below the water through hole and communicated with the water through hole 113, so that the valve component 2 has the function of collecting condensed water and dust impurities in the condensed water through the collecting tank 211, the valve component 2 can not reliably close the water through hole 113 due to the existence of the dust impurities in the condensed water, and the flue gas leakage is avoided, and the product reliability is improved.

When the total weight of the condensed water in the collecting tank 211, the water through hole 113 and the water collecting chamber 101 is smaller than the preset valve opening threshold, the valve assembly 2 is tightly pressed against the lower end surface of the water through hole 113 and closes the water through hole 113, at this time, the condensed water in the water collecting chamber 101 cannot flow into the valve chamber 102 through the water through hole 113, i.e. the condensed water is stopped from being discharged, and dust impurities in the condensed water are collected or deposited in the collecting tank 211, so that the dust impurities are prevented from entering the matching position of the valve assembly 2 and the water through hole 113. When the gravity of the condensed water in the water collecting chamber 101 is greater than a preset valve opening threshold value, the condensed water pushes the valve assembly 2 to move downwards so that a gap is formed between the valve assembly 2 and the lower end surface of the water through hole 113, at this time, the condensed water in the water collecting chamber 101 flows into the valve chamber 102 sequentially through the water through hole 113 and the gap, and is discharged out of the device and the gas heating water heater through the water outlet 131, in the process, the water seal is formed because the water level of the condensed water is still higher than the gap, so that the flue gas cannot leak outwards through the gap, and in addition, dust impurities are collected or deposited in the collecting groove 211 because of the existence of the dust impurities in the condensed water, so that the dust impurities cannot flow upwards into the gap, the valve assembly 2 cannot reliably close the water through hole 113 because of the existence of the dust impurities in the condensed water is prevented, thereby avoiding the leakage of the flue gas and improving the reliability of products.

When the condensed water is drained, as the condensed water in the water collection chamber 101 is reduced, the valve assembly 2 moves upwards, and when the total weight of the residual or remaining condensed water is smaller than a preset valve opening threshold value, the valve assembly 2 presses the lower end face of the water through hole 113 again and closes the water through hole 113, and the drainage of the condensed water is stopped.

It can be seen that by locating the valve chamber 102 below the water collection chamber 101 and adopting the water through hole 113 to communicate the valve chamber 102 with the water collection chamber 101, the valve assembly 2 is movably disposed in the valve chamber 102 up and down for opening or closing the water through hole 113, thus, the device can meet the requirements of condensate water collection and discharge, and can avoid smoke leakage. In addition, through being equipped with open-top's collecting vat 211 on valve assembly 2, collecting vat 211 is located the limbers below and communicates limbers 113 for valve assembly 2 has the function of collecting the dust impurity in comdenstion water and the comdenstion water, prevents to lead to valve assembly 2 to fail to reliably close limbers 113 because of there is dust impurity in the comdenstion water, ensures to keep good sealing performance under the comdenstion water exists dust impurity state, when further avoiding the flue gas leakage, improves product reliability.

A lower seal groove (in the figure) opened upward is formed between the outer circumferential wall of the lower cover 13 and the annular water blocking rib 134, and the third seal ring 15 is installed in the lower seal groove and clamped between the lower end surface of the water collecting box 11 and the lower cover 13, so that the annular water blocking rib 134 can prevent water in the valve chamber 102 from flowing to the third seal ring 15.

In this embodiment, the annular water blocking rib 134 is located radially outside the drain port 131 and the valve assembly 2, and all orthographic projections of the valve assembly 2 are located radially inside the annular water blocking rib 134, so that when condensate water flows into the valve chamber 102 from a gap between the valve assembly 2 and the lower end surface (i.e., partition portion) of the water through hole 113, the annular water blocking rib 134 can play a role of blocking the condensate water flowing down from the gap from flowing into the third seal ring 15.

Alternatively, the blockage detection device may be a water level sensor for detecting the water level of the water collection chamber 101, and when the water level sensor detects that the water level of the water collection chamber is greater than a set water level threshold, the set water level threshold is greater than a water level corresponding to a preset valve opening threshold, it may be directly determined that the water through hole 113 is blocked, or the water level continues to be greater than the set water level threshold for a period of time, and then it is determined that the water through hole 113 is blocked; on the contrary, it can be determined that the water passage 113 is not clogged.

Referring to fig. 3 to 4, the collecting tank 211 includes an upper concave cavity 2111 communicating with the water hole 113, and the upper concave cavity 2111 has a truncated cone shape or a truncated pyramid shape with a diameter narrowed from top to bottom, so that condensed water and dust impurities in the condensed water are conveniently guided to the lowest position of the upper concave cavity 2111. In this embodiment, the collecting tank 211 further includes a lower cavity 2112, the lower cavity 2112 is located below the upper cavity 2111 and is communicated with the upper cavity 2111, the cross-sectional area of the lower end surface of the upper cavity 2111 is not smaller than that of the upper end surface of the lower cavity 2112, so that the collecting capability of condensed water and dust impurities contained therein is increased by matching the communicated lower cavity 2112 with the upper cavity 2111, and the dust impurities collected in the upper cavity 2111 are more difficult to flow upwards to a gap, so that the reliability of closing the water through hole 113 by the valve assembly 2 is further improved, good sealing performance is ensured under the condition that the condensed water has dust impurities, and the reliability of products is improved.
