Abstract

The utility model relates to a safety device suitable for centrifugal pump, including the centrifugal pump body, install the outlet pipe on the centrifugal pump body, with the inlet tube of this body coupling of centrifugal pump, install the pump bottom valve bottom inlet tube one end and strain the cage, the inlet tube sets up the horizontal line below at the circulation liquid level, the valve is opened to cooperation setting between inlet tube and the centrifugal pump body. This safety device makes easy and simple to handlely, avoids because of the output of the sealed tight appearance of inlet tube and the condition that pressure reduces, easy maintenance.

Description

A kind of safety installations being applicable to centrifugal pump
Technical field
The utility model relates to machinery, particularly relates to a kind of safety installations being applicable to centrifugal pump.
Background technique
At present, the common device of circulating water is provided to be centrifugal pump in the industrial production, for the installation form of centrifugal pump substantially all higher than more than circulating water liquid level, the maximum advantage of such erection unit is easy to maintenance, but also there is following deficiency in actual production runs: 1. to add before starting quote water could normal startup optimization; 2. trouble when operation uses; 3., when supply pipe is poorly sealed, can air inlet causes water output and pressure to diminish, time serious, not take out water; 4. intake pipe tightness not easily checks.
Summary of the invention
For the defect that prior art exists, the utility model proposes a kind of safety installations being applicable to centrifugal pump, easy and simple to handle, avoid the situation of water output and the pressure reduction occurred because intake pipe is poorly sealed, easy to maintenance.
For achieving the above object, the utility model proposes a kind of safety installations being applicable to centrifugal pump, comprise centrifugal pump body, be arranged on the outlet pipe on centrifugal pump body, the intake pipe be connected with centrifugal pump body, be arranged on the pump bottom valve bottom intake pipe one end and filter cage; Described intake pipe is arranged on below the horizontal line of circulation liquid level; Open valve is equipped with between described intake pipe and centrifugal pump body.
Described open valve is arranged on the position near centrifugal pump body.
Described open valve is butterfly valve.
Beneficial effect:
The utility model, by below the horizontal line that intake pipe is arranged on circulation liquid level and open valve etc., makes easy and simple to handle, avoids the situation of water output and the pressure reduction occurred because intake pipe is poorly sealed, easy to maintenance.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
1. pump bottom valve, 2. intake pipe, 3. circulation liquid level, 4. open valve, 5. outlet pipe, 6. centrifugal pump body, 7. circulating water pool.
Embodiment
In order to make the purpose of this utility model, technological scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
As shown in the figure, a kind of safety installations being applicable to centrifugal pump, comprises centrifugal pump body 6, is arranged on the outlet pipe 5 on centrifugal pump body 6, the intake pipe 2 be connected with centrifugal pump body 6, is arranged on the pump bottom valve 1 bottom intake pipe 2 one end and filter cage; Described intake pipe 2 is arranged on below the horizontal line of circulation liquid level; Open valve 4 is equipped with between described intake pipe 2 and centrifugal pump body 6.
Described open valve 4 is arranged on the position near centrifugal pump body 6.
Described open valve 4 is butterfly valves.
Centrifugal pump is arranged on below the liquid level of circulating water pool 7 by the utility model, and the intake pipe 2 be connected with centrifugal pump body 6 adds a butterfly valve 4, and it is excellent as follows:
1. circulating water pool 7 fills the intake pipe 2 of centrifugal pump after water remarks is full simultaneously, can start at any time; Simple to operate.
2. be very easy to find intake pipe 2 whether good seal.
4. overcome the water output and pressure reduction phenomenon that cause because intake pipe 2 is poorly sealed.
5. during maintenance, the butterfly valve on intake pipe cuts out, keeps in repair very convenient.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection domain of the present utility model.
