Description

Float trap

The invention relates to a pipeline condensed water discharge device, in particular to a float-type trap that has the functions of improving drainage stability and preventing vapor and gas leakage.

According to, there are various types of water eliminators nowadays, such as thermal dynamic type, thermal static type, inverted bucket type, flow hole type and floating ball type, etc. The float type water eliminator has been launched several decades ago. The floating ball is the main link, and the free float method has recently been developed. The condensate drain is designed to be located at the oblique angle of the valve body. When the float is used in the water body, it will be close to the drain under pressure. Therefore, a closed water stop function is formed. However, when the water is discharged at a low water level, there will be a co-emission of condensed water and vapor gas (commonly known as the gas emission phenomenon). The leakage of the vapor gas will not only cause a waste of energy, but also There is a risk of accidental touch and injury caused by high-temperature eruption. Therefore, how to overcome the leakage of vapor and gas when draining. Moreover, the conventional free float is easily affected by the turbulence of vapor and the dripping of condensed water, resulting in shaking In the case of deviation, the free float will be far away from the discharge port at this time, making it temporarily lose the function of preventing gas discharge. The above-mentioned deficiency is the technical problem that the creation intends to improve.

When the buoyancy ball 30 does not block the When the valve nozzle 20 is used, the inflow pipe 51 and the outflow pipe 52 can pass through the valve chamber 11, the drain hole 23, the bottom channel 12 and the side channel 13 to form a communication, thereby completing the combination of their structures.

The actual use situation, please continue to observe from Figures 4 and 5 in conjunction with Figure 2. When a small amount of condensed water flows into the valve chamber 11 of the valve body 10 from the end of the inflow pipe 51, the condensed water can pass through the The filter screen 40 drips on the bottom of the valve chamber 11. At this time, the water has not yet been able to support the buoyancy ball 30, and the buoyancy ball 30 is pressed against the valve due to the weight of the body and the internal pressure of the valve body 10. The nozzle 20 forms a hermetic effect through the roundness of the buoyancy ball 30 and the arc lead angle 221 of the valve nozzle 20 to prevent gas leakage when the condensate water is insufficient, and when the amount of condensate water rises, The condensed water causes the buoyancy ball 30 to generate buoyancy and leave the valve nozzle 20, allowing the condensed water to flow into the bottom channel 12 and the side channel 13 through the drain hole 23, and the outlet pipe 52 of the connecting seat 50 communicates with the side channel 13 And the position of the outflow pipe 52 is higher than the valve port 111 of the valve chamber 11. When the internal pressure of the valve body 10 is insufficient or a small amount of water accumulates, the condensed water still cannot be discharged from the end of the outflow pipe 52, thus effectively maintaining the valve chamber 11. The amount of stagnant water inside, and through sufficient amount of stagnant water to block gas, which effectively prevents gas leakage, and can ensure that only the condensed water is discharged, thereby achieving the purpose of gas blocking and effective drainage. It is also worth noting that The valve body 10 is equipped with the filter 40 in the valve chamber 11. The filter hole 41 of the filter 40 can not only filter the impurities in the condensed water, but also use the flat filter 40 to resist Eliminate the turbulence when the gas flows in, and form uniform dripping of condensed water, thereby preventing the buoyancy ball 30 from shaking in the valve chamber 11, reducing the possibility of gas leakage in the state of insufficient water accumulation, and making the buoyancy ball 30 can function stably. Another technical means of this creation, please cooperate with Figure 7. When the buoyancy ball 30 is deflected due to shaking, the inner wall of the valve chamber 11 of the valve body 10 will Limit the offset of the buoyancy ball 30 so that when the buoyancy ball 30 abuts against the inner wall of the valve chamber 11, the other part of the buoyancy ball 30 only a single point abuts against the guide of the valve nozzle 20 On the pull ring 222, the center of gravity of the buoyancy ball 30 will now fall close to the drainage hole 23, so the buoyancy ball 30 will directly roll to the drainage hole 23, thereby correcting the buoyancy ball 30 and returning In the original position, the buoyancy ball 30 can function smoothly when the drainage hole 23 needs to be sealed, so as to effectively improve the sealing stability.

Another embodiment of this creation, please refer to Figures 8, 9, and 10.

The expansion reed 18 can control the accelerated discharge of condensed water. When the valve body 10 is used in steam, because of the need to discharge low-temperature gas, the expansion reed 18 is used to expand and contract. The arc section 181 of 18 approaches the wall surface of the valve chamber 11 when the temperature rises, so that the buoyancy ball 30 can smoothly seal the drain hole 23, and when the temperature drops, the arc section 181 can push toward the buoyancy The ball 30 clamps the buoyancy ball 30 at a position where it does not interfere with the valve nozzle 20, thereby allowing the low-temperature gas to be discharged in advance, so as to provide an additional use function of discharging low-temperature gas.

In summary, the present invention has indeed achieved a breakthrough structural design, and has an improved content of the invention. At the same time, it can achieve industrial applicability and progress, and the present invention has not been seen in Any publication is also novel. When it complies with the relevant provisions of the Patent Law, Yan filed an application for a patent for invention in accordance with the law. I implore the Jun Bureau review committee to grant a legal patent.
