Abstract

The utility model provides a novel domestic manual high pressure well pump, which can pump groundwater in flat ground for families and can supply water outside at a high pressure. The utility model has the advantages of no easy damage, easy overhaul, low cost, etc.

Description

A kind of novel household high pressure manual well head

The utility model relates to a kind of novel family's level land groundwater abstraction, and can the outside family expenses high pressure manual well head that supplies water of high pressure.

In the prior art, family's level land groundwater abstraction, and outwards the device of high service has two kinds: a kind of impeller-type electric self priming pump that is to use extracts; Another kind is to extract manually by family expenses high pressure manual well head.The former in use, often because of using method, all multifactor influences such as maintenance, pump case very easily occurring breaks, phenomenons such as motor water inlet, in easy to use, also brought the trouble of repair to the user, its usage charges are also higher, and the described high pressure manual well head of the latter, because what its hydrating structure sealing was adopted is the mode of common rubber sealing, compactness is very poor, often six months the rubber sleeve subscription rate that both had been worn, this in addition high pressure manual well head is generally family or the workshop-based production of semiworks, do not have on the market can be general with it accessory can change for repairing, be difficult to repair so damage the back.The well head of this " disposable " often brings unnecessary economic loss to the user.

It is strong that the purpose of this utility model provides a kind of compactness, not fragile, is easy to repair, and low-cost novel household high pressure manual well head.

The purpose of this utility model is achieved in that the sucker with high pressure manual well head of the prior art changes piston into, between former sucker and cylinder barrel the rubber that adopts sealing change piston ring packing into, formerly advance, the water sucting glue plastic valve changes steel valve into.

Change by piston and replace because the utility model is the main element sucker with former high pressure manual and head, and between itself and cylinder barrel, use piston ring packing, and advance, the improvement of suction valve, the compactness and the abrasion resistance that respectively seal the position have been improved to a great extent, prolonged application life, simultaneously because the family's groundwater abstraction and the required pressure that outwards supplies water are not too big, and the density of drawing requirement does not need too high yet, the cylinder barrel that general power machine maintenance is changed, piston, piston ring, all can meet the demands, be beneficial to repair and recycling, implement to be very easy to, corresponding required expense is also less.

Below in conjunction with drawings and Examples the utility model is elaborated.

Figure (1) looks sectional view for the master of the utility model family expenses high pressure manual well head.

By figure (1) as can be known, cylinder barrel (5) is placed on the well seat (1).Play stator bore (5) and well lid (18) effect vertical columns (4) be evenly distributed in cylinder barrel (5) around, (be generally three, also can 2 or 4,5 etc. some, among the figure for for the purpose of clear, be expressed as 2), its lower end is welded on the well seat (1), and the upper end is gone up the corresponding well lid fixing hole (6) from well lid (18) and is passed, the top is fastening by nut (7), and the cylinder barrel that more former like this high pressure manual well head is adopted is welded on to be easy to repair on the well seat and changes.Be placed with piston (16) in the tube of cylinder barrel (5), it both can adopt the former aluminum piston that matches with cylinder barrel, also can make by oneself.Depth pistion is generally according to one to three layer of piston ring (15) be advisable (also can 4,5 etc. several layers) can be installed, there is circular suction hole (17) (also to can be other shape at the middle part of piston (16), to change in order making to repair, to establish the junction plate (12) of a triangle (other shape also can) in the top in suction hole (17) in dismounting.The bottom of the connecting rod (8) of pulling piston (16) is fixed on the central authorities of junction plate (12) by the structure of screw, nut, junction plate (12) is by column (13) (be generally 3, also can 4,5 etc. some), the structure by screw, nut be fixed on piston (16) go up suction hole (17) around.The steel suction valve (14) that coincide with it is installed on the suction hole (17),, at the center of suction valve (14) hole is arranged, to coincide on the pin of connecting rod (8) lower end for the ease of the accurate return of suction valve (14).Between well lid (18) and connecting rod (8), have one by water seal (11), the compact texture of compositions such as nut (10) is adjusted in water gland (9) and water seal.

The utility model spurs the simplex pull rod of connecting rod (8) or accessories such as dual-gripper bar and handle in this description will be omitted in addition.

The utility model is work like this: by the effect of simplex pull rod and dual-gripper bar, when upwards spurring connecting rod (8), piston (16) moves upward, suction valve (14) is closed, inlet valve (3) is opened, water just enters in the cylinder barrel (5) of piston (16) bottom along inlet opening (2), when piston (16) when moving downward, inlet valve (3) is closed, suction valve (14) is opened, water just along suction hole (17) from the space between column (13) along junction plate (12) around enter in the chamber of the cylinder barrel (5) on piston (16) top and well lid (18) formation, because this chamber bottom is airtight by piston ring (15) and suction valve (14), when water level rose to the delivery port (19) that is positioned at well lid (18) sidewall, water promptly can be along outlet pipe flowing water or high pressure ejection.

According to test: this novel manual High-pressure well head, under the manual situation of adult, can carry out the high force feed water of 30 meters vertical heights easily, generally use and can not break down in 5～8 years.

Claims

1, a kind of novel household high pressure manual well head is made of cylinder barrel and piston, it is characterized in that: piston ring is installed on the piston.
