Abstract
(B, ) the utility model provides a buffering water -pump bottom valve belongs to the pumping plant field. It has solved the current water -pump bottom valve problem that the impact force is big of closing the door. This buffering water -pump bottom valve, which comprises the following components: a valve body, valve body upper end and lower extreme are equipped with delivery port and water inlet respectively, be equipped with the valve clack in the valve body, be connected with the valve rod on the valve clack, and valve rod sliding connection is lieing in the guide bracket of valve body, be equipped with hollow cushion collar on the water inlet, be equipped with the buffering hole in the cushion collar, the valve clack is the massive structure, and the valve clack has and cushions hole pore wall complex valve clack outer wall, still be fixed with the baffle on the valve rod, and can be through valve rod and guide bracket cooperation, it is downthehole to make the valve clack enter into the buffering, and make the valve clack outer wall and cushion the sealed laminating of hole pore wall, the baffle was laminated with the valve body that the water inlet upside corresponds this moment. At the valve clack turn -off transient, it is downthehole that the valve clack can enter into the buffering, through slowing down the velocity of flow with buffering hole cooperation to the impact force that brings is reduced when valve clack and valve body are closed, consequently life can be improved. (B, )
Description
Technical field
The utility model belongs to pumping plant technical field, relates to a kind of buffered water pump bottom valve.
Background technique
Bottom valve of water pump prolonged placement is operated under water, the moment when stopping pumping, and at closing time, what current brought closes the door impact force comparatively greatly to flap, easily causes sealed member to damage, is therefore necessary to improve.
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, can improve the buffered water pump bottom valve in working life.
The purpose of this utility model realizes by following technical proposal: a kind of buffered water pump bottom valve, 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, cushion hole is provided with in described cushion collar, described flap is block structure, and flap has the flap outer wall coordinated with cushion hole hole wall, described valve rod is also fixed with baffle plate, and coordinate by valve rod and guiding trestle, flap is made to enter in cushion hole, and flap outer wall and cushion hole hole wall are sealed fit, the valve body that now 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, slow down flow velocity by coordinating with cushion hole, thus reduce the impact force brought when flap and valve body are closed, avoid the direct and valve body of flap to impact and seal, therefore can play good cushioning effect, can working life be improved.
In above-mentioned a kind of buffered water pump bottom valve, described flap is cylindrical, and cushion hole is the circular port coordinated with flap outer wall, and 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 buffered water pump bottom valve, described flap is frustoconic shape, and cushion hole hole wall is the frustoconic shape structure coordinated with flap outer wall, and the larger one end of flap is near water outlet.
Therefore can slowly seal.
In above-mentioned a kind of buffered water pump bottom valve, described flap outer wall is arranged with some seal rings.
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, slow down flow velocity by coordinating with cushion hole, thus reduce the impact force brought when flap and valve body are closed, avoid the direct and valve body of flap to impact and seal, therefore can play good cushioning effect, can working life be improved.
Accompanying drawing explanation
Fig. 1 and Fig. 2 is this buffered water pump bottom valve two kinds of structural representations respectively.
In figure,
1, valve body; 11, water outlet; 12, water intake;
2, cushion collar; 21, cushion hole; 22, guiding surface;
3, flap; 31, valve rod; 32, guiding trestle; 33, baffle plate.
Embodiment
Be below specific embodiment of the utility model and by reference to the accompanying drawings, the technical solution of the utility model is further described, but the utility model be not limited to these embodiments.
As depicted in figs. 1 and 2, a kind of buffered water pump bottom valve of the utility model, comprise valve body 1, valve body 1 top and bottom are respectively equipped with water outlet 11 and water intake 12, flap 3 is provided with in valve body 1, flap 3 is connected with valve rod 31, and valve rod 31 is slidably connected at and is positioned on the guiding trestle 32 of valve body 1, water intake 12 is provided with hollow cushion collar 2, cushion hole 21 is provided with in cushion collar 2, flap 3 is in block structure, and flap 3 has flap 3 outer wall coordinated with cushion hole 21 hole wall, valve rod 31 is also fixed with baffle plate 33, and coordinate by valve rod 31 and guiding trestle 32, flap 3 is made to enter in cushion hole 21, and flap 3 outer wall and cushion hole 21 hole wall are sealed fit, the valve body 1 that now baffle plate 33 is corresponding with on the upside of water intake 12 is fitted.
Further, flap 3 is cylindrical, and cushion hole 21 is the circular port coordinated with flap 3 outer wall, and cushion hole 21 has annular guiding surface 22 towards the one end open place of water outlet 11.Or flap 3 is in frustoconic shape, and cushion hole 21 hole wall is the frustoconic shape structure coordinated with flap 3 outer wall, and the larger one end of flap 3 is near water outlet 11.Flap 3 outer wall is arranged with some seal rings.
During work, current drive flap 3 to be separated with water intake 12, when at flap 3 turn-off transient, flap 3 can enter in cushion hole 21, slow down flow velocity by coordinating with cushion hole 21, thus reduce the impact force brought when flap 3 is closed with valve body 1, avoid flap 3 directly and valve body 1 impact and seal, therefore can play good cushioning effect, can working life be improved.
