Abstract
The utility model discloses a pressure bucket used for an automatic water-feeding pump, which belongs to the technical field of pump corollary equipment. The utility model comprises a bucket body and a rubber diaphragm, wherein the bucket body is formed from two semicircular buckets which are made of plastic material and are welded into the integral bucket body under high pressure and high temperature; the rubber diaphragm which is sheathed in the bucket body is tightly embedded into a groove of the bucket body by a circle of outwards projecting flange on the circumference of the rubber diaphragm; the top part of the bucket body is provided with an air nozzle cap; the space between the inner end of the air nozzle cap and the top end of the air nozzle is provided with a sealing ring, the space between the lower end of the air nozzle cap and a concave pit at the top part of the bucket body is also provided with a sealing ring, thereby, a double sealing device of the air nozzle is formed. The utility model ensures a water outlet loop to be kept in the state that the pressure is full and the water is to be supplied. The utility model prolongs the service life of a product.
Description
One, technical field
The utility model discloses a kind of pressure pot that is used for the self water feeding pumping, belong to pumping support equipment technical field.
Two, background technology
Self water feeding engine pressure barrel structure commonly used, give seam again after all the semicircle bucket made from two metal materials cooperatively interacts, its inside pushes against a bowl-type rubber disc in staving central authorities with a flexible steel ring, staving is by aeration hole, top injecting gas, be full of the space of rubber disc top, and rubber disc is produced certain pressure.After starting pumping, water is promptly entered by the water inlet at the bottom of the bucket, with the rubber disc jack-up that makes progress, form a downward pressure behind its top gas pressurized, this pressure can stop action or during initial start in pumping, gives the water surface one suitable pressure, keeps full pressure to treat the water supply state thereby use water loop.
Above-mentioned pressure pot is owing to all be full of water from the following space of rubber disc, thereby the staving that metal material is made all need be done antirust processing.But last lower barrel body the time must be fixed with welding manner in combination, and the high temperature that is produced during welding causes antirust coat to damage easily, and in use for some time, staving easily produces corrosion, thereby has influence on the serviceable life of pressure pot.In addition, the sealing of individual layer O-ring seal is adopted in the aeration hole, also easily causes the gas of rubber disc top to leak, and makes the downward pressure shakiness, causes the frequent starting of water pump.
Three, summary of the invention
The purpose of this utility model is to provide a kind of and guarantees out that water loop keeps full pressure to treat the water supply state, and prolongs the pressure pot modified self water feeding engine pressure bucket in serviceable life.
For achieving the above object, the technical solution adopted in the utility model is: self water feeding engine pressure bucket, comprise the plastics staving, and be sheathed on the diaphragm of rubber of staving inwall, the valve of gas nozzle cap is equipped with at the staving top, and valve is provided with the two-layer equation packoff.Described two-layer equation packoff by place the rectangular seal between the inner and valve top of gas nozzle cap and place the gas nozzle cap lower end and the pit at staving top between O-ring seals form.Bottom one side of staving is provided with the flange that can connect with water pump, but the bottom opposite side of staving is provided with the interface of setting pressure switch.Establish a support column in the middle of the staving bottom.There is the flange that a circle outwards protrudes closely to embed in the groove of staving on the periphery of diaphragm of rubber.Staving is that semicircle bucket welding under High Temperature High Pressure of being made by two plastic materials forms an integral body.
After the utility model adopted technique scheme, its advantage was:
(1) the two-layer equation packoff is set on the valve, diaphragm of rubber top gas is difficult for leaking, and has guaranteed sealing property.
(2) there is the flange that a circle outwards protrudes closely to embed in the groove of staving on the periphery of diaphragm of rubber, guaranteed the sealing between the upper and lower cavity.
(3) staving is that semicircle bucket welding under High Temperature High Pressure of being made by two plastic materials forms an integral body, can not produce corrosion, makes water storage keep clean, has prolonged pressure pot serviceable life.
(4) bottom one side of staving is provided with the flange that can connect with water pump, establishes a support column in the middle of the staving bottom, has easy installation and reliable advantage.
Four, description of drawings
Fig. 1 is the utility model front view;
Fig. 2 is the utility model A-A cut-open view shown in Figure 1.
Five, embodiment
As shown in Figure 1 and Figure 2, self water feeding engine pressure bucket, comprise that semicircle bucket welding under High Temperature High Pressure of being made by two plastic materials forms holistic staving 1, by the diaphragm of rubber 2 that is sheathed on staving 1 hypomere inwall in the groove 11 of the outside flange that the protrudes 10 tight embedding stavings 1 of a circle on its periphery.Diaphragm of rubber 2 is divided into upper and lower two cavitys 12,13 with staving 1.Staving 1 top is provided with on valve 3, the valve 3 gas nozzle cap 4 is housed, and between gas nozzle cap 4 the inners and valve 3 tops rectangular seal 5 is arranged, and is provided with O-ring seals 6 between the pit at gas nozzle cap 4 lower ends and staving 1 top, thereby forms the double seal of valve 3.Staving 1 bottom right-hand member is provided with the flange 7 that can connect with water pump, but staving 1 bottom left end is provided with the interface 8 of setting pressure switch, establishes a support column 9 in the middle of staving 1 bottom.
Principle of work of the present utility model is such: at first in the formed cavity 12 of upper inside wall of diaphragm of rubber 2 and staving 1, be injected with the gas of certain pressure by valve 3.During pump operation, when depotition cock is closed, the pressure that enters the water of staving 1 bottom from flange 7 will rise, will up push up diaphragm of rubber 2, along with the rising of hydraulic pressure, the formed cavity 13 of the diaphragm of rubber 2 and the lower inner wall of staving 1 is enlarged, correspondingly the moisture storage capacity in it also and then increases, when water route pressure is increased to certain value, just impel pressure switch to disconnect, allow water pump shut down; When water pump shuts down, because gaseous tension is by the effect in 2 pairs of water routes of diaphragm of rubber in the cavity 12, make and still can keep certain pressure in the water route, thereby make pressure switch keep the state that disconnects, avoided the frequent starting of water pump, and use water loop and also keep full pressure to treat the water supply state during water pump shuts down, depotition cock is once opening water outlet; Open when depotition cock one, water route pressure just reduces thereupon, and water route pressure one reduces, and pressure switch is just recovered closed state, and water pump restarts.
