Abstract
The utility model relates to an adjustable internal-discharging single-way safety valve assembly. A one-way valve is additionally arranged on the original safety valve assembly. The one-way valve has transverse holes which are communicated with the holes of a safety valve. A threaded hole on the left side of the one-way valve body is provided with a screw bolt. When the water pressure in a water tank exceeds the standard water pressure, water flows in the one-way valve and pushes away a top plate, and then the water flows in the inner cavity of the original safety valve assembly and is discharged from a water supply pipe which is communicated with the lower end of the inner cavity of the original safety valve assembly. Normally, the pressure of the one-way valve is always lower than the pressure of the one-way safety valve on the right side of the one-way valve, so that the overpressure water is first discharged from the left side and is led to the water supply pipe. The utility model mainly adopts an internal discharging mode, and the defect that the water outlet of the safety valve has dripping water is avoided.
Description
The utility model relates to a kind of adjustable interior row's one-way relief valves assembly, belongs to the safety valve technical field of electric water heater.
Electric water heater is popularized throughout the country gradually, but because the pressure of supply water of different regions, different floors is widely different, and each manufacturer continues to increase the heating function of electric water heater in the commodity competition process, but the pressure divergence standard of one-way relief valves does not allow to improve; Therefore under big hydraulic pressure, powerful condition, it is a lot of that electric water heater casing internal pressure in using temperature-rise period is made the pressure divergence that will inevitably exceed the safety valve regulation in the short time, make safety valve make the user feel discontented aspect the draining release, think it is the defect of leaking by mistake, constantly present one's view.For this reason, tackle this shortcoming and make corresponding improvement.
The purpose of this utility model is that a kind of adjustable interior row's one-way relief valves assembly will be provided, and it can overcome above-mentioned shortcoming.Mainly add in original safety valve left side and adorn an one-way valve, the water row who makes superpressure desire row can eliminate the defect that the safety valve drain opening is dripped basically to water supply line.
The purpose of this utility model is achieved in that to add on the valve body (5) at former safety valve adorns an one-way valve, the left side in the hole (23) of the valve body of former safety valve (5) has transverse holes (26) to be communicated with the vertical core (30) of left side one-way valve, and vertical core (30) communicates with hole (28) again; Top board (21) is housed in the hole (28), spring (18) is housed on top board (21) the bottom nose (34), spring (18) lower end is supported by adjusting nut (16), again with sealing nut (15) roof pressure.This nut and valve body (5), hole wall step place, hole (28) are provided with a rubber pad (17), hole (28) left side tapped holes (31) bolt (19) of packing into, and right side, hole (28) has a cross-drilled hole (29) to lead to hole (24), and a sealing gasket (22) is arranged at top board (21) top.Bottom, hole (28) hole wall in valve body (5) left side has a nose (39), and this nose contacts with sealing gasket (22).

Now in conjunction with the accompanying drawings the structure of electric water heater one-way relief valves is described in detail:
By Fig. 1, in the top valve pocket (23) of valve body (5) middle part part a top board (1) is housed, top board (1) top is spring (2) and adjustable cap (3), one sealing gasket (4) is arranged below the top board (1), the valve pocket (24) of valve pocket (23) and bottom connects with the aperture (25) at middle part, valve pocket (23) left and right side respectively has transverse holes (26), (27) be communicated with vertical core (30) and hole (32) of left side one-way valve respectively, vertical core (30) and hole (28) are communicated with, top board (21) is housed in the hole (28), spring (18) is housed on top board (21) the bottom nose (34), spring (18) lower end is supported by adjusting nut (16), again with sealing nut (15) this nut of roof pressure (16), sealing nut (15) and valve body (5), hole wall step place, hole (28) is provided with a rubber pad (17), hole (28) left side tapped hole (31) bolt (19) of packing into, hole (28) right part also has a cross-drilled hole (29) to lead to hole (24), and a sealing gasket (22) is arranged at top board (21) top.
Top board (8) and spring (7) are housed in the hole (32) of valve body (5) right part, top board (8) left side is sealing gasket (6), one pull bar (12) is arranged in the spring (7), adjusting nut (11) is in right side supported spring (7), packing ring (10) is loaded on adjusting nut (11) right side, and the end of pull bar (12) is stretched out on packing ring (10) right side; Handle (9) is fixed on the end of pull bar (12) with bearing pin (34), and the bottom of handle (9) is passed a bolt (14) and is fixed in the lower thread hole (35) of valve body (5) right part by a nut (13) to a lateral bending song in its terminal hole.
On the bottom end face of hole (35) nose (36) is arranged all, this nose (36) contacts with sealing gasket (6).Equally, also there is a nose (37) to contact on the bottom end face of hole (23) with sealing gasket (4).
By Fig. 2, projection (38) is arranged at the bottom of valve body (5) right part, has hole (33) and tapped hole (35).
By Fig. 3, on the bottom end face of hole (32) nose (36) is arranged, same hole (28) has nose (39), hole (23) that nose (40) is arranged.
By Fig. 4,7, original one-way relief valves of one-way valve and middle right part can be integral by the A-A position grouping.
By Fig. 5,6, one-way valve and original one-way relief valves can be integral by A-B, A-C position grouping.
By Fig. 8, similar among the structure of original one-way relief valves and Fig. 1, just there is not the one-way valve part of left part, its structure is no longer repeated.
This structure is that original body cavity epimere is communicated with hole (26), (30) with the check valve body that increases newly, push top board (21) open in the check valve body on the left of the water of the interior superpressure of electric water heater casing (figure does not show) injects, flow in the valve body hole and inject in the hole (24) of former one-way valve inner chamber bottom, and be communicated with discharge with water supply line by a side cross-drilled hole (29).
From the structure of Fig. 1 as can be seen, the newly-increased one-way valve pressure in left side is lower than the pressure on right side, so inevitable the discharge from the left side earlier of the water of superpressure be led to water supply line in the casing, but the drain opening on right side can not drip out under normal conditions; If run into the factor of contingency, the pressure in the casing increases suddenly, and the one-way relief valves drain opening on right side is moved the draining release at once, has guaranteed the safety of water tank thus.
This structure can be combined into one one-way valve and original one-way relief valves, and top and the bottom are joining water box and water supply line respectively, and one-way valve is separated with original one-way relief valves, is communicated with water tank and water supply line respectively up and down.(figure is omitted)
Compared with prior art, electric heater one-way safety valve module has following advantages:
1. can be according to the different regions pressure of supply water, the heating power of electric heater is adjusted internal discharging type non-return valve and is pressed Power makes it a little less than the about 0.03-0.05Mpa of the pressure that effluxes delivery port, and with superpressure in the casing The water of discharging has then solved the safety valve discharge outlet and water droplet occurred now discharged to inner (being water supply line) Resemble.
One-way valve and original safety valve can make up in aggregates, also separable opening.
3. one-way valve can place the front and back side of left side or safety valve.
4. simple in structure, cost is not high.
5. use upward safe and reliable.
