CN2550535Y - Automatic seal joint - Google Patents

Abstract

The utility model relates to a self-sealing connector, which is characterized in that: a clapboard 2 provided with certain intensity and a round hole 5 in the middle is fixed at the corresponding place in the rubber pipe joint 1; a guide bolt 3 is fixed on the clapboard; a seal valve 4 which can seal the round hole 5 of the clapboard is connected in series on the bolt 3; one side of the seal valve of the pipe joint is connected with a water pump, and the other side is connected with a tee. The seal valve is opened for pumping when the water pump absorbs water; the seal valve automatically closes the round hole of the clapboard and separates channel between the water pump and the tee when the water pump stops absorbing, and the water diversion of well head is not affected. The water pump can be matched with the well head, so as to use water pump in large water using and use well head in less water using. In addition, the function of self-priming pump can be achieved if a sealing joint is connected between the tee and the well casing. The utility model has the advantages of simple structure, low price and convenience and practicality, which is applicable for pumping in rural well casing.

Description

Self-sealing joint

One, technical field

The utility model relates to a kind of SEALING FITTING, the self-sealing joint of using on the pipe well of especially a kind of suitable rural area.

Two, background technique

At present, rural area pipe well water lift one is to utilize lever principle with the artificial water lift of well head, and this method effort is time-consuming, and the water yield of being carried is little.The 2nd, by the water pump water lift, save time though this method is laborsaving, the water yield that draws up is big, and the diversion difficulty is extremely inconvenient during a small amount of water.Also useful three-way pipe links together well casing, well head, water pump three, takes out with well head during water in a small amount, inhales with water pump during a large amount of water.And this method does not have reverse seal arrangement owing to be connected by free flow coupling between water pump and the three-way pipe, diversion difficulty when causing well head to draw water, even do not draw water.

Three, summary of the invention

In order to solve the deficiencies in the prior art, the utility model provides a kind of self-sealing joint, and this joint is connected in and can makes well head and water pump be easy to respectively water be drawn up between three-way pipe and the water pump.

The technological scheme that its technical problem that solves the utility model adopts is: the relevant position is by the dividing plate with certain intensity of fixing middle band circular hole of rubber in rubber fittings, be fixed with guide blot on the dividing plate, string has the rubber sealed valve of seal diaphragm circular hole automatically on the bolt.The seal valve side joint of pipe joint is on water pump, and the other end is connected on the three-way pipe; When pump sump, seal valve is opened water is extracted out, and when water pump stopped inhaling, seal valve enclosed baffle circular hole cut off the water pump passage, does not influence the diversion of well head.

The beneficial effects of the utility model are: because a seal valve is set in rubber fittings, this valve is opened the seal diaphragm circular hole automatically under the effect of suction, water pump, well head are used, and realizes that the convenient of the large and small water yield utilizes.This joint structure is simple, and is convenient and practical, is convenient to make, and low price is the indispensable accessory that the rural area pipe well draws water and uses.

Fig. 1 is a sectional structure chart of the present utility model.

Fig. 2 is mounting point figure of the present utility model.

Among the figure 1, pipe joint, 2, dividing plate, 3, guide blot, 4, seal valve, 5, circular hole, 6, well head, 7, three-way pipe, 8, water pump, 9, well casing.

Five, embodiment

In the accompanying drawings, the pipe joint 1 usefulness ebonite of self-sealing joint is made, and utilizes the elasticity of rubber to be docked to the last and sealing of other pipe easily.A dividing plate 2 with certain intensity is fixed by rubber in neutral position in the rubber fittings 1, and the centre of dividing plate 2 has circular hole 5, the fixing guide blot 3 in the relevant position on the disc of dividing plate 2, and going here and there on the bolt 3 has rubber sealed valve 4, the nut of screwing on after on the string.Seal valve 4 side joints of pipe joint 1 are on water pump 8, and opposite side is connected on the three-way pipe 7.During water pump 8 suctions, valve 4 is opened and is drawn water, and water pump stops inhaling valve 4 automatic enclosed baffle circular holes 5, cuts off the passage of three-way pipe 7 and water pump 8, easily water is drawn when well head 6 draws water.In addition, also can establish a self-sealing joint between three-way pipe 7 and the well casing 9, be full of water in the three-way pipe 7, when starting pump motor repeatedly, the air water in the emptying well casing will be extracted out, can reach the effect of self-priming pump.

Claims (1)

1, a kind of self-sealing joint, it is characterized in that the relevant position is by the dividing plate with certain intensity (2) of fixing middle band circular hole (5) of rubber in rubber fittings (1), the relevant position of dividing plate (2) is fixed with guide blot (3), and guide blot (3) is gone up string the seal valve (4) of enclosed baffle circular hole (5) automatically.
