Summary of the invention
The purpose of this utility model is for the above-mentioned problems in the prior art, provides one and has resiliency of closing the door very well, and sandstone can be avoided to block affect the sand prevention bottom valve of water pump sealing configuration of sealing.
The purpose of this utility model realizes by following technical proposal: a kind of sand prevention bottom valve of water pump sealing configuration, comprise valve body, valve body top and bottom are respectively equipped with water outlet and water intake, flap is provided with in valve body, flap is connected with valve rod, and valve stem slides is connected to and is positioned on the guiding trestle of valve body, it is characterized in that: water intake is provided with hollow cushion collar, circular hole cushion hole is provided with in described cushion collar, described valve rod is also fixed with baffle plate, described flap is cylindrical, and flap outer wall is provided with O-ring seal, and flap is also provided with the annular that two hard metals make and scrapes Sha Huan, seal ring and scrape Sha Huanjun and flap is coaxially arranged, and two are scraped Sha Huan and are located at the both sides of seal ring along flap axis, scraping end, Sha Huan outer is round-blade shape, and coordinate by valve rod and guiding trestle, make flap along flap shaft to entering in cushion hole, and scrape Sha Huan outer and cushion hole hole wall is fitted, and seal ring and cushion hole hole wall are sealed, and the valve body that baffle plate is corresponding with on the upside of water intake is fitted.
During work, current drive flap to be separated with water intake, when at flap turn-off transient, flap can enter in cushion hole, flow velocity is slowed down by coordinating with cushion hole, thus reduce the impact force brought when flap and valve body are closed, avoid flap directly and valve body impact and seal, therefore can play good cushioning effect, can working life be improved, and when being attached with sandstone in cushion hole, strike off by scraping Sha Huan outer, avoid card between seal ring and cushion hole hole wall to have sandstone, affect sealing, thus can sealing effect be strengthened.
In above-mentioned a kind of sand prevention bottom valve of water pump sealing configuration, described cushion hole has annular guiding surface towards the one end open place of water outlet.
Guiding surface plays the effect of guiding.
In above-mentioned a kind of sand prevention bottom valve of water pump sealing configuration, described flap outer wall is provided with outside thread, scrapes Sha Huan and has internal thread, and scrapes Sha Huan and be screwed onto on flap.
In above-mentioned a kind of sand prevention bottom valve of water pump sealing configuration, described flap outer wall is provided with annular seal groove, and seal ring is enclosed within seal groove.
Therefore be convenient to dismounting and change seal ring and scrape Sha Huan.
Compared with prior art, the utility model tool has the following advantages:
During work, current drive flap to be separated with water intake, when at flap turn-off transient, flap can enter in cushion hole, flow velocity is slowed down by coordinating with cushion hole, thus reduce the impact force brought when flap and valve body are closed, avoid flap directly and valve body impact and seal, therefore can play good cushioning effect, can working life be improved, and when being attached with sandstone in cushion hole, strike off by scraping Sha Huan outer, avoid card between seal ring and cushion hole hole wall to have sandstone, affect sealing, thus can sealing effect be strengthened.
