Description
Technical field
The utility model relates to a kind of pipeline water hammer protective gear of eliminating the pipeline water hammer effect.
Background technique
Now pipe-line system is according to the water hammer effect principle, when the stopping and starting of water pump, owing to tube wall is smooth; Follow-up current reach maximum rapidly under action of inertia, can produce destruction to pipeline; Can address this is that as a water-hammer arrester (pressure release orifice) is set in pipeline, therefore when producing water hammer effect, can enlarge equipment inlet flow; Immediately slow down the impact that pipeline is stressed, to reach the purpose of protection pipeline.But when receiving water hammer effect, the bore of inlet is constant at inlet for existing water hammer equipment, and the impact that receives current is big, causes breakage, can not eliminate water hammer effect on the contrary, has also shortened the working life of pipeline.
Summary of the invention
The purpose of the utility model provide a kind of simple in structure, effectively slow down the pipeline water hammer protective gear that hydraulic pressure that pipeline produces because of water hammer effect impacts, prolongs the working life of pipeline and equipment.
The utility model is achieved in that
A kind of pipeline water hammer protective gear; Comprise water storage tank, be connected to loam cake and blind flange on the water storage tank upper and lower end opening, leather bag is located at water storage tank inside; The opening of leather bag is fixed on the opening of water storage tank lower end through blind flange; Water storage tank open upper end place between leather bag and the loam cake is provided with the gas bleeder valve assembly, and the inboard inlet of described blind flange is provided with catch, and a side of catch is hinged on the blind flange; Catch is provided with plural water port, and catch is in the inner chamber of leather bag.
Outside thread on the above-mentioned gas bleeder valve assembly passes the opening of seal ring, water storage tank upper end, the packing ring in the tank body outside successively in the inboard of water storage tank, cooperate with outside thread on the gas bleeder valve assembly with the air valve nut gas bleeder valve assembly is screwed onto on the water storage tank opening of loam cake inboard.
The upper end of above-mentioned air valve nut is provided with the cap head.
Above-mentioned water port has seven.
The middle part of above-mentioned water storage tank outer surface is provided with the flange circle.
The utility model is compared the outstanding advantage of existing technology:
Several apertures are arranged on the catch that is provided with in the utility model, and when not receiving water hammer effect, the water in jar is supplemented in the pipeline through the aperture on the catch; When receiving water hammer effect, current are gone out tube wall, open catch simultaneously; Enlarged inflow; The more effective pipeline that slows down prolongs the working life of pipeline and equipment because of the hydraulic pressure that water hammer effect produces impacts, and is useful on the various pipe-line systems.

Fig. 2-Fig. 5 is the user mode schematic representation of the utility model;
Fig. 6 is the Placement of gas bleeder valve assembly in the utility model.
Embodiment
With specific embodiment the utility model is further described below, referring to Fig. 1-6:
A kind of pipeline water hammer protective gear; Comprise water storage tank, be connected to loam cake 10 and blind flange 90 on the water storage tank 50 upper and lower end openings, leather bag 80 is located at water storage tank 50 inside; The opening of leather bag 80 is fixed on the opening of water storage tank 50 lower ends through blind flange 90; Water storage tank 50 open upper end places between leather bag 80 and the loam cake 10 are provided with gas bleeder valve assembly 70, and described blind flange 90 inboard inletes 93 are provided with catch 92, and a side of catch 92 is hinged on the blind flange 90; Catch 92 is provided with plural water port 920, and catch 92 is in the inner chamber of leather bag 80.
Outside thread on the above-mentioned gas bleeder valve assembly 70 passes the packing ring 40 in opening, the tank body outside of seal ring 60, water storage tank 50 upper ends successively in the inboard of water storage tank 50, cooperate with outside thread on the gas bleeder valve assembly 70 with air valve nut 30 the gas bleeder valve assembly is screwed onto on water storage tank 50 openings of loam cake 10 inboards.
The upper end of above-mentioned air valve nut 30 is provided with cap head 20.
Above-mentioned water port 920 has seven.
The middle part of above-mentioned water storage tank 50 outer surfaces is provided with flange circle 51.
According to above-mentioned structure, the working principle of the utility model: when pipeline does not receive water hammer effect, < the precompressed air pressure in the water storage tank 50 of the hydraulic pressure in the pipeline; Water in this moment water storage tank 50 are supplemented in the pipeline through the water port on the catch 92 920, when receiving water hammer effect, the hydraulic pressure in the pipeline>precompressed air pressure in the water storage tank 50; Current are gone out tube wall; Open catch simultaneously, current get into from inlet 93, and the diameter of inlet 93 is greater than the diameter of water port 920; Therefore just enlarged flow of inlet water; The more effective pipeline that slows down is because of the hydraulic pressure that water hammer effect produces impacts, prolong pipeline and equipment working life (precompressed air pressure is 1.3-1.8bar in above-mentioned, but air pressure according to compression of air and pressure rises).
The foregoing description is merely one of preferred embodiment of the utility model; It is not the practical range that limits the utility model with this; So: the equivalence that all shapes according to the utility model, structure, principle are done changes, and all should be covered by within the protection domain of the utility model.
