Abstract
A displacement pump protecting device which comprises a valve and a displacement pump is characterized in that an outlet pipeline of the displacement pump and the normally closed type spring valve are connected through a fast-assembling type catch hoop. The displacement pump protecting device which has the outlet pipeline of the displacement pump and the normally closed type spring valve connected through the fast-assembling type catch hoop has the advantages of simple structure and reliable performances. Furthermore, the displacement pump protecting device thoroughly solves the problems of excessive pump pressure and cleaning difficulty.
Description
Technical field
The utility model belongs to the displacement pump overvoltage protective device, specifically is a kind of displacement pump protective gear.
Background technique
Displacement pump is meant that the variation that utilizes the pumping cylinder internal volume carries the pump of liquid.As reciprocating pump, rotor pump, screw pump etc.Reciprocating pump is to utilize the to-and-fro motion of piston to carry the pump of liquid, by the to-and-fro motion of piston energy is directly transmitted liquid with the form of static energy.Rotor pump is made up of static pump case and rotor rotated, and it does not have suction valve and expulsion valve, and a side that contacts with liquid by the rotor in the pump housing directly acts on liquid with energy with the static pressure form, and borrows the squeezing action drain of rotor.The displacement pump outlet throttling is obstructed, and pressure is significantly increased, and can produce cavitation erosion even infringement pump and pipeline when serious.Displacement pump is to produce the essential conveying equipment of sour milk, and now a lot of factories load onto the bypass reduction valve at the volume delivery side of pump, and this kind device deficiency is: bypass is arranged, and cleaning is influenced, and cleaning has the dead angle, may have microbial contamination.The factory that has does not then adorn bypass, directly uses, and is relatively more dangerous.
The model utility content
The utility model provides a kind of displacement pump protective gear, is installed in the displacement pump outlet, when pressure is excessive, can open protection pump and pipeline automatically.
The purpose of this utility model realizes by following technical solution:
A kind of displacement pump protective gear comprises valve and displacement pump, it is characterized in that: use the ready-package clip connected between the outlet conduit of said displacement pump and the normal close type spring valve.
Displacement pump protective gear of the present utility model is used the ready-package clip connected between displacement pump outlet conduit and the normal close type spring valve; Simple in structure, reliable performance has thoroughly solved the problem of overhigh pumping pressure and non-easy cleaning.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Among the figure 1 is clip, the 2nd, and valve, the 3rd, displacement pump.
Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail.
Is connected with ready-package clip 1 between displacement pump of the present utility model 3 devices, displacement pump outlet conduit and valve 2, can installs by hand disassembly without instrument, be convenient to the manual inspection maintenance of cleaning, the distance between pipeline and the valve is shorter, and cleaning does not have the dead angle.Valve is a single normal close type spring valve, and is normally closed by the effect of spring, do not need electric and control system.When milk hydraulic coupling during greater than the elastic force of spring, valve is backed down, and reaches decompression protection, and valve and link are the stainless steel foodstuff sanitation-stage.
When pump discharge pressure is excessive, can back down spring, releasing pressure automatically reaches the purpose of protecting displacement pump.
Claims (1)
1. a displacement pump protective gear comprises valve and displacement pump, it is characterized in that: use the ready-package clip connected between the outlet conduit of said displacement pump and the normal close type spring valve.
