Technical field

The present invention relates to prefabricated pumping plant technical fields, and in particular to a kind of backwash valve of prefabricated pumping plant.

Background technique

With the development of urban construction, the amount of municipal rainwater, sewage is more and more, therefore various sewage occurs Processing equipment, pumping plant are one of them.

Prefabricated pumping plant more general at present includes pumping plant pedestal, cylinder and water pump.Various deposits are easy in cylinder Bottom deposit, deposit, which overstays, can generate the substance that foul smell etc. has corrosiveness to the structure in pumping plant, so that water pump Work condition environment it is more severe, influence the service life of water pump, while usually thering is serious sludge to deposit, periodically need artificial clear It becomes silted up to guarantee water pump normal use, this work is not only cumbersome, and has certain danger for dredging personnel.

In order to solve above situation, by regularly backwashing, the automatic running time of prefabricated pumping plant can be appropriately extended, It carrying out backwash and needs to be arranged backwash valve, existing backwash valve needs to increase power part, and control program is controlled, Consuming energy, and it is at high cost；Long period of soaking is in the cylinder with various sewage simultaneously, and there are some potential safety problemss.

Summary of the invention

It is not necessarily to extra power the technical problems to be solved by the present invention are: providing, avoids security risk and energy-saving and environment-friendly The backwash valve of prefabricated pumping plant.

In order to solve the above-mentioned technical problem, the technical solution adopted by the present invention are as follows:

A kind of backwash valve of prefabricated pumping plant, the prefabricated pumping plant includes water pump, and the water pump includes water outlet, described anti- Flushing valve includes valve body, valve deck, spool and floating body, and the valve body includes the first interconnected opening, the second opening and the Three openings, the spool setting is between the first opening and the second opening；First opening is connected to the water outlet of water pump；

In third opening, the floating body passes through valve deck by connector and connect with spool for the valve deck setting；It is described floating The connection and partition of valve core movement control the first opening and the second opening are driven when body moves.

The beneficial effects of the present invention are: by float controlled valve core, and then control the company of the first opening with the second opening Logical and partition, can be realized the open and close of backwash valve, can directly utilize the buoyancy and spool floating body of liquid in cylinder Gravity controlled, and inner barrel is cleaned using a part of flow and lift of water pump；Structure is simple It is durable, prolong the service life, without additional power, security risk, and energy conservation and environmental protection is not present.

Detailed description of the invention

Label declaration: 1, valve body；11, the first opening；12, the second opening；13, first passage；14, second channel；2, valve Lid；3, spool；4, floating body；5, link the body of rod；6, the flexible body of rod；7, limited block；8, sealing ring.

Specific embodiment

To explain the technical content, the achieved purpose and the effect of the present invention in detail, below in conjunction with embodiment and cooperate attached Figure is explained.

Fig. 1 is please referred to, a kind of backwash valve of prefabricated pumping plant, the prefabricated pumping plant includes water pump, and the water pump includes The mouth of a river, the backwash valve include valve body 1, valve deck 2, spool 3 and floating body 4, and the valve body 1 includes that first to be interconnected opens Mouthful 11, second opening 12 and third opening, the setting of spool 3 is between the first opening 11 and the second opening 12；Described first Opening 11 is connected to the water outlet of water pump；

In third opening, the floating body 4 passes through valve deck 2 by connector and connect with spool 3 for the setting of valve deck 2；Institute State the connection and partition when floating body 4 moves with 3 motion control first of movable valve plug opening 11 and the second opening 12.

As can be seen from the above description, by 4 control valve core 3 of floating body, and then control the company of the first opening 11 and the second opening 12 Logical and partition, can be realized the open and close of backwash valve, can directly utilize the buoyancy and 3 floating body of spool of liquid in cylinder 4 gravity is controlled, and is cleaned using a part of flow and lift of water pump to inner barrel；Structure is simple It is durable, prolong the service life, without additional power, security risk, and energy conservation and environmental protection is not present.

Further, the connector is the linkage body of rod 5.

Further, it is connected between the linkage body of rod 5 and spool 3 by the flexible body of rod 6.

As can be seen from the above description, can guarantee that spool 3 connects with being fully sealed for valve body 1 by the setting of the flexible body of rod 6 Touching.

Further, limited block 7 is provided on one end that the linkage body of rod 5 is connect with the flexible body of rod 6.

As can be seen from the above description, can be avoided the linkage body of rod 5 by limited block 7 for the flexible body of rod 6 and pull out valve body 1 together, It avoids resetting difficult problem,

Further, the floating body 4 is hollow sphere.

Further, the spool 3 is sphere.

Further, the part that first opening 11 is connected to the second opening 12 is first passage 13, and the third is opened The part that mouth is connected to first passage 13 is second channel 14, is provided with and 3 phase of spool on the inner sidewall of the first passage 13 The groove of cooperation, the spool 3 move in groove and second channel 14.

As can be seen from the above description, can more be bonded spool 3 by the setting of groove, guarantee the compactness of partition.

Further, the prefabricated pumping plant further includes cylinder, and second opening 12 is towards cylinder body bottom.

Further, sealing ring 8 is additionally provided between the valve deck 2 and third opening.
