Abstract

The utility model discloses a dredge device for a bottom valve of a pump suction pipe, which comprises a pump inlet pipe, a bottom valve, a valve core and a pull ring arranged on a valve core body. A branch pipe is arranged on the inlet pipe, a dredge valve is positioned on the branch pipe, and a hanging hook is downwards arranged at the top end of the branch pipe. By means of the device, if the bottom valve is blocked, a motor is shut down at first, the dredge valve is opened, the hanging hook is placed in from the position of the dredge valve to hook the pull ring at the top of the valve core of the bottom valve, and the valve core can be lifted and water remained in the pipe flows back to clean the blocked bottom valve. After the bottom valve is cleaned, the hanging hook is taken off, the dredge valve is closed, and a pump can be started normally. The dredge device for the bottom valve of the pump suction pipe is simple in structure, low in cost and capable of effectively reducing cleaning labor intensity and saving cleaning time.

Description

A kind of dredging device of pump suction pipe bottom valve

Technical field

The utility model relates to the dredging device of sewage pump, slag stock pump suction pipe bottom valve.

Background technique

Sewage pump, slag stock pump in the course of the work because the pump suction pipe bottom valve is because of accumulation of impurities in the medium results in blockage in bottom valve, cause suction pipe inhale sky cause the pump conveying capacity to reduce and fault frequent.It is termination of pumping that tradition bottom valve impurity stops up dredging method, remove suction pipe, does the labor cleaning by proposing bottom valve in the water; Although traditional dredging method can thoroughly be cleared up the impurity of bottom valve and stop up, pump dead time is long in the mediation process, work difficulty is big, manpower that drop into is many, cause security incident easily, brings considerable influence to production.

By on can know that above-mentioned existing bottom valve mediation obviously has defective and exists, and remains to be improved.

Thus, the improving of the above-mentioned defective of the utility model thoughts is that the spy concentrates on studies and cooperates repetition test, proposes a kind of reasonable in design and effectively improve the model utility of above-mentioned defective finally.

Summary of the invention

To the deficiency of existing technology, the utility model aims to provide a kind of dredging device of pump suction pipe bottom valve, guaranteeing to dredge process safety, quick, and reduces labor intensity.

The technological scheme that the utility model adopts; A kind of dredging device of pump suction pipe bottom valve comprises the draw ring on pump inlet pipe, bottom valve, spool and the spool body, on said inlet tube, arm is set; The mediation valve is set on said arm, hook is set downwards from the top of arm.

After adopting said apparatus, if bottom valve blockage phenomenon, at first disable motor; Open the mediation valve, from the mediation valve hook is put into, and hooked the draw ring at bottom valve spool top; Can mention spool; Pour in down a chimney the cleaning of accomplishing the bottom valve obstruction with residuary waters in the pipe, after cleaning work is accomplished, take out hook, close the normal boot-strap that the mediation valve just can recover pump.

The utility model is simple in structure, and cost is low, can effectively reduce cleaning labor intensity, saves clearance time.

Description of drawings

Fig. 1 is the utility model structural representation;

In the accompanying drawing: 1 bottom valve, 2 spools, 3 draw rings, 4 hooks, 5 arms, 6 mediation valves, 7 inlet tubes, 8 sewage pumps.

Embodiment

Below in conjunction with accompanying drawing the utility model is described further.

As shown in Figure 1, the upper end-hole of inlet tube 7 connects sewage pump, and inlet tube 7 lower end mouth connect bottom valve 1, behind sewage pump 8 work certain hours, on the filter screen of bottom valve 1, can assemble dirt, influences sewage pump 8 conveying capacitys.On inlet tube 7 tops arm 5 is set, mediation valve 6 is set on arm 5, open mediation valve 6, hook 4 is set downwards, just can hook draw ring 3 on the spool 2 with linking up with 4 from the top of arm.

In the cleaning work before the utility model does not have to try out, need 2 to 3 check mans to on-the-spot bottom valve to be removed, clear up, whole process labor intensity is bigger, and the length that expends time in, and is bigger to the production influence.After two waterback pump bottom valves of accident pool and inlet tube are transformed, in the existing cleaning work, only need 1 site operation personnel just can carry out; This device in the work of bottom valve cleaning, has been saved great amount of manpower and material resources since input in 2010 is on probation, also improved the operation utilization rate of equipment to a certain extent.

The above; Be merely the utility model embodiment's embodiment; But the protection domain of the utility model is not limited thereto; Any those of ordinary skill in the art are in the technical scope that the utility model discloses, and conspicuous variation or replacement all should be encompassed within the protection domain of the utility model.

Claims
