Abstract
The utility model discloses a novel automatic exhaust valve device for a vertical type multi-stage pump and belongs to a booster water pump of a water supply system in people lives. The novel automatic exhaust valve device for the vertical type multi-stage pump is characterized in that: an exhaust valve body is provided; the lower end of the exhaust valve body is connected with an exhaust bolt in a matching manner; the side end of the exhaust bolt is connected with a hinged body in a matching manner; a combined gasket is arranged between the exhaust bolt and the hinged body; the other end of the hinged body is connected with a hinged bolt in a matching manner; and another combined gasket is arranged between the hinged body and the hinged bolt. The novel automatic exhaust valve device for the vertical type multi-stage pump has following beneficial effects: the device is simple and convenient to assemble and can be installed and operated by non-professional staff by themselves; during safe operation of the water pump, air is gathered due to a curved pipeline and can be exhausted from the automatic exhaust valve at any time; dry abrasion of the mechanical seal and seal damage can be avoided; the safe operation of the water pump is ensured so that users can normally use water without interruption; and the novel automatic exhaust valve device for the vertical type multi-stage pump is advantaged by being simple in structure and easy in installation or transformation; and is also convenient and reliable in operation and is substantial in social and economic benefit.
Description
Technical field
The utility model relates to the booster water pump of people's domestic water system, is a kind of novel MODEL VERTICAL MULTISTAGE PUMP automatic exhaust valve device for the vertical multi-stage water pump specifically.
Background technique
The booster water pump of residential quarter domestic water system is selected the vertical multi-stage water pump of mechanical seal at present, water pump mechanical seal (also claiming end face seal) has the remarkable advantages such as good sealing effect, low in energy consumption, leakage rate is little, maintenance is few, one of machine foundation element of belong to accurate, structure is comparatively complicated, but price is more expensive.
Newly install at present or put into operation after while cutting off the water again water, air is arranged, after water pump is opened in pump chamber, mechanical seal runs up, and the high temperature that friction produces can't obtain cooling, makes the operation of graphite annulus (sound end face) lack of water, dry friction damages, economic loss.Existing traditional operating method need to manually be opened the plug of water pump top relief opening, treats that air drains, after making liquid be full of whole pump chamber, then the manual-lock venting plug.The shortcoming of this bleeding be to adopt manual exhaust, and water pump operation is to adopt the Automatic Control mode.Manual exhaust will be operated by the personnel of specialty, sometimes even needs repeatedly exhaust, and water pump is normally started, not only waste of manpower, and can't guarantee in time to resume water supply.
The model utility content
In order to overcome the deficiency of existing product, the purpose of this utility model is to provide a kind of simple in structure, and what be easy to install or transform is a kind of for the MODEL VERTICAL MULTISTAGE PUMP automatic exhaust valve device.
The technological scheme that its technical problem that solves the utility model adopts is: a kind of novel MODEL VERTICAL MULTISTAGE PUMP automatic exhaust valve device, it is characterized in that: an exhaust valve is arranged, the lower end connection of exhaust valve is combined with bleeder screw, the side connection of bleeder screw is combined with articulated body, be provided with bonded washer between bleeder screw and articulated body, the other end connection of articulated body is combined with hinge bolt, is provided with bonded washer between articulated body and hinge bolt.
The utility model can install a bleeder screw hole additional at original manual exhaust mouth side, with hinge bolt, it is connected with articulated body, the articulated body two ends install the bonded washer sealing additional, exhaust valve is fixed on articulated body, when the inner water-filling of water pump, air in pump chamber is under the effect of hydraulic pressure, by the aperture in articulated body, bleeder screw and hinged breechblock, discharge from the valve port of outlet valve, after air drained, floating ball body floated rapidly, withstood valve opening sealing place, outlet valve is closed automatically, need not professional workforce's manual exhaust.
The feature of the utility model vertical multi-stage water pump automatic control pressure vent is: the relief opening angle of each water pump manufacturer production is different, and automatic control pressure vent can, by adjusting the angle of articulated body, make outlet valve keep vertical.
Described bleeder screw is arranged on Vertical direction.
Described articulated body is arranged on traditional outlet valve lower end.
Described hinge bolt is used for connecting bleeder screw and articulated body.
The beneficial effects of the utility model are: due to the utility model automatic exhaust valve device simple installation, the layman also can install voluntarily, operation.Water pump, automatically in service,, because of the air that the pipeline detour is assembled, can be discharged by automatic control pressure vent at any time, avoids mechanical seal unlubricated friction scrape along seal break-off, has guaranteed the safe operation of water pump, guarantees that user's water does not interrupt.Simultaneously, the utlity model has simple in structurely, be easy to the advantage of installing or transforming.
Description of drawings
Below in conjunction with drawings and Examples, the utility model is conducted further description.
Fig. 1 is structural representation of the present utility model.
In figure 1, exhaust valve, 2, bleeder screw, 3, bonded washer, 4, articulated body, 5, hinge bolt.
Embodiment:
Originally be implemented in original manual exhaust mouth place and install a bleeder screw additional, with hinge bolt, it is connected with articulated body, the articulated body two ends install the bonded washer sealing additional, and outlet valve is fixed on articulated body, the pump inlet valve of fetching boiling water, outlet valve is automatically with Bas Discharged.
The present embodiment is the described articulated body of MODEL VERTICAL MULTISTAGE PUMP automatic exhaust device, hinge bolt, bleeder screw employing stainless steel material mass-energy proof strength and non-corrosive; Embodiment also can substitute with brass etc., and the automatic control pressure vent of its upper end can be selected stainless steel, brass or plastic material.
Embodiment 1:
An exhaust valve 1 is arranged, the lower end connection of exhaust valve 1 is combined with bleeder screw 2, the side connection of bleeder screw 2 is combined with articulated body 4, be provided with bonded washer 3 between bleeder screw 2 and articulated body 4, the other end connection of articulated body 4 is combined with hinge bolt 5, is provided with bonded washer 3 between articulated body 4 and hinge bolt 5.
