Abstract

The utility model relates to a device for connecting case jar and pump, include: case jar, its discharge mouth of pipe pass through the one end of the first valve of pipe connection, the other end of first valve passes through the pipeline to be connected with the one end of a bending pipeline, the one end of second valve pass through the pipeline with first valve is connected, the other end connecting tube of second valve and with duct extension to trench or pit, the pump, the one end of first mechanical tubes and the one end of second mechanical tubes are connected respectively with exporting to its entry, the other end of first mechanical tubes pass through the expansion joint with the other end of bending pipeline is connected, the discharge mouth of pipe of case jar is less than highly arranging of the entry of pump. The beneficial effects of the utility model are that: it is jar external to make below the pump intake elevation partial fluid passage pump discharge, has increased jar internal actual volume that utilizes, reduces the fluid volume volume of arranging to the pit simultaneously.

Description

The connecting device of a kind of case tank and pump

Technical field

The utility model relates to the connecting device of a kind of case tank and pump, is specifically related to a kind of following partially liq of pump intake absolute altitude that can make by the connecting device of the external case tank of pump drain tank and pump.

Background technology

Between existing tank body discharge orifice and horizontal pump entrance, connecting tube adopts same level height placement (adjusting the layout of height containing eccentric reducer), when vertical distance between making at the bottom of pump intake height and tank is higher, pot liquid below pump intake duct height is not discharged by pump, in tank body, remaining liquid can not be transferred system utilization simultaneously, need emptying once tank body, can only be expelled to by the discharge side at the bottom of tank in corresponding melt pit, retain in hole or discharged by pump.

Utility model content

For the weak point existed in the problems referred to above, the utility model provides a kind of following partially liq of pump intake absolute altitude that can make by the connecting device of the external case tank of pump drain tank and pump.

For achieving the above object, the utility model provides the connecting device of a kind of case tank and pump, comprising:

Case tank, it discharges the mouth of pipe connects the first valve one end by pipeline, the other end of described first valve is connected by pipeline one end with a bending pipeline, one end of second valve is connected with described first valve by pipeline, and pipeline is also extended to trench or melt pit by the other end connecting tube of described second valve;

Pump, its entrance and exit connects one end of the first shape tube and one end of the second shape tube respectively, and the other end of described first shape tube is connected by the other end of expansion joint with described bending pipeline;

The discharge mouth of pipe of described case tank is lower than the height placement of the entrance of described pump.

Improve further as the utility model, an elbow is respectively established at the two ends of described bending pipeline.

Improve further as the utility model, the angle of described elbow is 1-α, wherein ， α≤90 °.

The beneficial effects of the utility model are: the following partially liq of pump intake absolute altitude can be made external by pump drain tank, and to add in tank body actual utilizes volume, reduces the liquid capacity amount draining into melt pit simultaneously.

Accompanying drawing explanation

Fig. 1 is the structural representation of the connecting device of a kind of case tank of the utility model and pump.

In figure: 1, case tank; 21, the first valve; 22, the second valve; 3, expansion joint; 41, the first shape tube; 42, the second shape tube; 5 pumps.

Detailed description of the invention

As shown in Figure 1, a kind of case tank described in the utility model embodiment and the connecting device of pump, comprise case tank 1, pump 5 and coupling.

The discharge mouth of pipe of case tank 1 connects one end of the first valve 21 by pipeline, the other end of the first valve 21 is connected by pipeline one end with a bending pipeline, one end of second valve 22 is connected with the first valve 21 by pipeline, and pipeline is also extended to trench or melt pit by the other end connecting tube of the second valve 22.The entrance and exit of pump 5 connects one end of the first shape tube 41 and one end of the second shape tube 42 respectively, and the other end of the first shape tube 41 is connected with the other end of bending pipeline by expansion joint 3.The discharge mouth of pipe of case tank 1 is lower than the height placement of the entrance of pump 5.

Wherein, an elbow is respectively established at the two ends of bending pipeline, and the angle of band elbow is 1-α, wherein ， α≤90 °.

During concrete use: during pump operation, when vertical distance between at the bottom of pump intake height and tank is higher, pot liquid below pump intake duct height is discharged by pump, in tank body, remaining liquid can be transferred system utilization, add effective use liquid capacity of tank body, reduce the liquid capacity amount draining into melt pit.

The foregoing is only preferred embodiment of the present utility model, be not limited to the utility model, for a person skilled in the art, the utility model can have various modifications and variations.All within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
