Abstract
The utility model relates to a diaphragm-type non-return device of a ball loading chamber, which is characterized by including a punching valve plate, wherein sleeves are fixed at the two ends at the top of the punching valve plate; a valve rod is arranged in the two sleeves and can rotate in the sleeves; and a positioning mounting plate is fixed on the valve rod. Compared with the prior art, the utility model has the advantages that the diaphragm-type non-return device has an ingenious structure, can effectively prevent back flow of glueballs, improve the ball collection rate of the system, and reliably guarantees the operation and maintenance of the glueball cleaning system as the damaged glueballs can be replaced timely.
Description
Technical field
The utility model relates to the dress ball equipment in a kind of rubber ball cleaning system, and especially a kind of ball load chamber diaphragm type check device belongs to valve technology field.
Background technique
Rubber ball cleaning system for steam condenser is the visual plant that steam turbine heating power is improved in the thermal power plant.Under the situation of the lotus of not lightening the burden, realize automatic cleaning,, improve heat exchange efficiency, improve condenser vacuum, reduce gross coal consumption rate to improve the turbidity test of water-cooling tube to condenser cooling water inner tube wall dirt.Avoid wall erosion simultaneously, prolong the working life of water-cooling tube.Using native system is one of effective measures that realize unit safety, efficient, economical operation.
The ball load chamber water intake of existing technology does not have check device, changes over to when receiving spherical attitude when closing switching valve, has a large amount of glueballs to reflux in the ball load chamber, can not get accurate data when causing counting ball, and ball collecting rate is low; Can't change the glueballs of whole damages when changing the shuttle; The cleaning efficiency of glueballs is low during operation.
Summary of the invention
The purpose of the utility model is to overcome the deficiency that exists in the existing technology; A kind of ball load chamber diaphragm type check device is provided, and this apparatus structure is ingenious, stops the backflow of glueballs effectively; Change the glueballs that damages in time, thereby guarantee the operation and the repair and maintenance of rubber ball cleaning system reliably.
The technological scheme that provides according to the utility model; A kind of ball load chamber diaphragm type check device, characteristic is: comprise the punching valve block, the difference fixed sleeving at the two ends, top of said punching valve block; In two sleeve pipes, valve rod is set, said valve rod can be rotated in sleeve pipe.
On said valve rod, be fixed with the location and installation plate.
The utility model compared with prior art, advantage is: this apparatus structure is ingenious, stops the backflow of glueballs effectively, has improved the ball collecting rate of system; The glueballs of damage be can change in time, thereby the operation and the repair and maintenance of rubber ball cleaning system guaranteed reliably.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Fig. 2 is the left view of Fig. 1.
Embodiment
Below in conjunction with concrete accompanying drawing the utility model is described further.
Like Fig. 1～shown in Figure 2: ball load chamber diaphragm type check device comprises punching valve block 1, sleeve pipe 2, valve rod 3, location and installation plate 4 etc.
The utility model comprises punching valve block 1; Said punching valve block 1 is steel plate line cutting backlash hole forming; Fixed sleeving 2 is welded at two ends, top at said punching valve block 1 respectively; In two sleeve pipes 2, valve rod 3 is set, valve rod 3 relative two sleeve pipe 2 centered, said valve rod 3 can be rotated in sleeve pipe 2; On said valve rod 3, be welded with location and installation plate 4.
The utility model is in working order the time, valve block 1 under flow action, together with sleeve pipe 2 around valve rod 3 rotations, all smooth and easy entering ball load chamber of glueballs and medium, and when backflow took place, valve block 1 compressed intake pipe under flow action, medium back flow, and glueballs is by non-return.
New structure of the present invention is ingenious, stops the backflow of glueballs effectively, has improved the ball collecting rate of system; The glueballs of damage be can change in time, thereby the operation and the repair and maintenance of rubber ball cleaning system guaranteed reliably.
