Abstract

The utility model provides a pressure relief device of impeller pump, includes relief valve and impeller pump, the relief valve comprises valve body, spring and top stick, the top stick is equipped with the boss, the spring housing is established on a stick, spring one end offsets with the boss of top stick, the spring other end and valve body offset, relief valve and clamp link to each other, the top stick withstands relief valve valve mouth via the elastic reaction of spring, formation closed type relief valve, be equipped with O type sealing washer in the clamp, export pipeline is connected simultaneously to the clamp, export pipeline and impeller pump are connected. When impeller pump outlet pressure is too big, can back down the spring, automatic pressure release reaches the purpose of protecting the impeller pump.

Description

A kind of pressure relief device of impeller pump
Technical field
This utility model belongs to pumping unit technical field, is specifically related to a kind of pressure relief device of impeller pump.
Background technology
Impeller pump is made up of the rotor of static pump case and rotation, and it does not have inlet valve and dump valve, by turning in the pump housing Energy is directly acted on liquid by the side that son is contacted with liquid in static pressure form, and the squeezing action by means of rotor is discharged Liquid, the medium stronger for high temperature, high viscosity and corrosivity, once outlet throttling is obstructed, can be such that pressure significantly increases, sternly The cavitation erosion even infringement pump housing can be produced during weight, now many factories load onto bypass air relief valve, this kind of device in the outlet of impeller pump Weak point is:There is bypass, cleaning is impacted, cleaning has dead angle, it is understood that there may be microorganism pollution.Some factories then do not fill Bypass, directly uses, than relatively hazardous.
The content of the invention
This utility model mainly solves the technical problem existing for above-mentioned prior art, there is provided a kind of pressure release of impeller pump Device, by the relief valve on outlet conduit, can automatically open up when pressure is excessive, protect pump and pipeline.
What above-mentioned technical problem of the present utility model was mainly addressed by following technical proposals:A kind of impeller pump Pressure relief device, including relief valve and impeller pump, the relief valve is made up of valve body, spring and top rod, and the top rod is provided with boss, The spring is set on the rod of top, and the boss of the spring one end and top rod offsets, and the spring other end and valve body offset, institute State relief valve to be connected with clip, O-ring seal is provided with the clip, the clip is while connection outlet pipeline, the outlet Pipeline and impeller pump connect.
Used as preferential, the top rod withstands relief valve valve port via the elastic reaction of spring, forms closed type relief valve.
Used as preferential, the clip can be opened and closed, by handle adjusting elasticity.
This utility model has the advantage that:By being connected with ready-package clip between impeller pump outlet conduit and relief valve Connect, the elastic of clip is adjusted by handle, loading and unloading is without extracting tool, as long as regulation handle can be completed, be easy to manual clear Wash, Inspection and maintenance, pipeline is shorter with the distance between valve, and cleaning is inlaid with O-ring seal without dead angle in clip, work as clip When tightening, the O-ring seal in clip pushes down outlet road junction and relief valve valve port, it is therefore prevented that the seepage of liquid, and relief valve is One single closed type spring valve, the effect by spring is normally closed, is not required to electric and control system.When rotor pump discharge pressure When excessive, spring can be backed down, releasing pressure automatically reaches the purpose of protection impeller pump.Therefore, this utility model have it is reasonable in design, The characteristics of simple structure.
Description of the drawings

Specific embodiment
Below by embodiment, and accompanying drawing is combined, the technical solution of the utility model is described in further detail.
Embodiment:A kind of pressure relief device of impeller pump, as shown in Fig. 1~Fig. 2, including relief valve and impeller pump, it is described to let out Pressure valve is made up of valve body, spring and top rod, and the top rod is provided with boss, and the spring is set on the rod of top, the spring one end Offset with the boss of top rod, the spring other end and valve body offset, the top rod withstands pressure release via the elastic reaction of spring Valve valve port, forms closed type relief valve, and the relief valve is connected with clip, and O-ring seal, the card are provided with the clip Hoop can be opened and closed, and by handle adjusting elasticity, the clip is while connection outlet pipeline, the outlet conduit and impeller pump connect.
Adjusted by handle by using ready-package clamp connection, the elastic of clip between impeller pump outlet conduit and relief valve, Loading and unloading, as long as regulation handle can be completed, is easy to manual cleaning, Inspection and maintenance, between pipeline and valve without extracting tool Distance it is shorter, cleaning is inlaid with O-ring seal, the O-ring seal when clip is tightened, in clip without dead angle in clip Push down outlet road junction and relief valve valve port, it is therefore prevented that the seepage of liquid, relief valve is a single closed type spring valve, Effect by spring is normally closed, is not required to electric and control system.When rotor pump discharge pressure is excessive, spring, automatic leakage can be backed down Pressure, reaches the purpose of protection impeller pump.
Finally it is pointed out that above example is only the more representational example of this utility model.Obviously, this practicality is new Type is not limited to above-described embodiment, can also there is many deformations.It is every according to technical spirit of the present utility model to above example Any simple modification, equivalent variations and the modification made, is considered as belonging to protection domain of the present utility model.
