Abstract
The utility model provides a door is clapped to counter weight constitutes by clapping door, pillar, counter weight urceolus, connecting piece, support, rubber slab, weight balancing ball, hinge, pillar, counter weight urceolus and clap fixed setting of door and be in the same place, the weight balancing ball diameter slightly is less than counter weight outer tube diameter, weight balancing ball can roll in the counter weight urceolus, seal at counter weight urceolus both ends. During water pump work, clapping the door and opened by rivers action of impulsive force, the high rear end of counter weight urceolus front end is low, the smooth counter weight urceolus rear end of rolling of weight balancing ball, and the moment that weight balancing ball produced reduces to clap antithetical couplet written on doors water pressure, reaches energy -conserving purpose, during the water pump stop work, clapping the door and closing under the dead weight effect, the low rear end of counter weight urceolus front end is high, the smooth counter weight urceolus front end that rolls of weight balancing ball, and door is clapped to counter weight claps the samely with conventional, has the stability that satisfies the designing requirement. A door is clapped to counter weight not only possesses energy -conserving function but also do not change the conventional stable advantage of door of clapping.
Description
Technical field
This utility model belongs to pump station engineering technical field, specifically a kind of counterweight flap valve.
Background technology
Flap valve is widely used cutout mode in small and medium-sized pumping station, and its Main Function is to prevent rivers tidewater from pouring in down a chimney, and is passed
The flap valve of system considers the stability after closing, and is designed to what is started upwards, backs down flap valve by the impulse force of current, and current are from bat
The lower section of door is flowed out, and flap valve hinders the flowing of current in operation always, produces larger hydraulic loss, with medium-sized axial-flow pump is
Flap valve will be continued jack-up, flap valve by pumping for water pump impulse force up to 450kg during unit operation by example, cast iron flap valve quality always
It is pressed on head for a long time and consumes much electricity, reduces water pump efficiency.Prior art takes mitigation flap valve for reducing energy consumption
Various measures to water outlet water flow pressure, have reached energy-conservation purpose, but have occurred in that flap valve closes the problem of rear stability difference, this kind of
If flap valve has very big risk, Chinese patent CN 202090429 in being applied to the rivers such as the Qiantang River that there is spring tide
U Counterbalanced flap valves are exactly to reduce the one kind of flap valve to outlet pressure by counterweight block, and other downward swing doors, side are opened the door
Patented technology, energy-saving principle are similar to, and energy consumption is reduced, bad stability.
Utility model content
In order to solve above-mentioned technical problem present in prior art, this utility model provides a kind of with retaking
Door, is made up of flap valve, pillar, counterweight outer tube, connector, bearing, rubber slab, weighted spherical ball, hinge, and described props up
Together with post, counterweight outer tube are fixedly installed with flap valve, counterweight bulb diameter is slightly less than counterweight outer tube internal diameter, and weighted spherical ball can be in counterweight
Roll in outer tube, the sealing of counterweight outer tube two ends ensures that weighted spherical ball is not affected by the external environment, and sliding rolling is smooth；Flap valve opening angle
When maximum, with hinge as fulcrum, torque of the torque that flap valve side produces more than generations such as rear side weighted spherical balls ensures that water pump stops
During work, flap valve declines under Gravitative Loads.
A kind of counterweight flap valve disclosed in this utility model, during pump working, flap valve is opened by impulsive force effect, outside counterweight
The high rear end in cylinder front end is low, and weighted spherical ball is slided and is rolled into the outer tube rear end of counterweight, and the torque that weighted spherical ball is produced reduces flap valve to water flow pressure, reaches
To energy-conservation purpose；When water pump quits work, flap valve is closed under Gravitative Loads, and the low rear end of counterweight outer cylinder front end is high, and weighted spherical ball is slided
Counterweight outer cylinder front end is rolled into, counterweight flap valve is identical with conventional flap valve, with the stability for meeting design requirement.A kind of counterweight flap valve
Not only had power saving function but also do not changed conventional flap valve stability advantages.
Description of the drawings
Fig. 1 is a kind of counterweight flap valve closed mode schematic diagram；
Fig. 2 is the flap valve closed mode schematic top plan view；
Fig. 3 is the flap valve closed mode vertical section schematic diagram；
Fig. 4 is the flap valve working condition vertical section schematic diagram.
Specific embodiment
The utility model is described in further detail below in conjunction with the accompanying drawings.
As Figure 1-4, a kind of counterweight flap valve of the present utility model, by flap valve 1, pillar 2, counterweight outer tube 3, connector
4th, bearing 5, rubber slab 6, weighted spherical ball 7, hinge 8 are constituted, and described pillar 2, counterweight outer tube 3 and flap valve 1 are fixedly installed on one
Rise, 7 diameter of weighted spherical ball is slightly less than 3 internal diameter of counterweight outer tube, weighted spherical ball 7 can be rolled in counterweight outer tube 3,3 two ends of counterweight outer tube
Sealing, when 1 opening angle of flap valve is maximum, with hinge 8 as fulcrum, the torque that 1 side of flap valve produces is produced more than 7 grade of rear side weighted spherical ball
Raw torque.
When a kind of counterweight flap valve of the present utility model is used, during pump working, flap valve is opened by impulsive force effect, counterweight
The high rear end of outer cylinder front end is low, and weighted spherical ball is slided and is rolled into the outer tube rear end of counterweight, and the torque that weighted spherical ball is produced reduces flap valve to water flow pressure,
Reach energy-conservation purpose；When water pump quits work, flap valve is closed under Gravitative Loads, and the low rear end of counterweight outer cylinder front end is high, weighted spherical ball
Cunning is rolled into counterweight outer cylinder front end, and counterweight flap valve is identical with conventional flap valve, with the stability for meeting design requirement.
