Fig. 1 is the utility model relates to a be applied to the level flow slipknot (not coveing the delivery port) of heating system at the family and look at the section-plane, fig. 2 is the utility model relates to a be applied to the level flow slipknot second regulating plate top view of heating system at the family, fig. 3 is the utility model relates to a level flow slipknot locating plate top view of heating system at the family is applied to the level flow slipknot of heating system at the family as shown in the figure, a be applied to the level flow slipknot of heating system at the family, including adjustment mechanism and guiding mechanism. The outer side of a guide sleeve 1 of the guide mechanism is provided with a guide sealing sleeve 2, the inner part of the guide sleeve 1 is provided with an adjusting mechanism, and a valve clack 3 of the adjusting mechanism is connected with the guide sleeve 1 through a diaphragm 4. A spring 5 is arranged between the upper part of the valve clack 3 and the guide sealing sleeve 2, and a plurality of water outlets 6 are uniformly arranged on the side wall of the upper part of the guide sealing sleeve 2. A flow adjusting plate 7 is arranged in the fixing groove below the valve clack 3, and a second adjusting plate 13 below the flow adjusting plate 7 is provided with a positioning rod in sliding connection with the guide sealing sleeve 2, the guide sleeve 1 and the through groove in the side wall of the slipknot 10. The guide sealing sleeve 2 penetrates through a through hole between adjacent positioning rods and is connected with a mounting groove of a positioning plate 8 below the second adjusting plate 13. The second adjusting plate 13 and the positioning plate 8 are both provided with a shielding plate 14 and a water passing slot hole 15, and the shielding plate 14 and the water passing slot hole 15 are both of sector structures connected with the circle centers of the second adjusting plate 13 and the positioning plate 8. The guide mechanism limits the movement range and direction of the adjusting mechanism, and the adjusting mechanism adjusts the size of the water outlet 6. When water enters, pressure difference is generated between the lower part of the slipknot 10 and the valve clack 3 and between the flow regulating plate 7 and the lower part of the valve clack 3, and first acting force which is upward to the valve clack 3 is generated. The spring 5 is in a compressed state and exerts a second downward force on the flap 3. The first acting force and the second acting force interact with each other to drive the valve clack 3 to move up and down along the guide sleeve 1. When the valve clack 3 moves, the upper part of the membrane 4 covers the water outlet 6 in different degrees, so that the flow of the water outlet 6 is adjusted according to the condition of the water inlet 11, and the flow of the water outlet 6 is kept constant. If the difference between the first acting force and the second acting force is not controllable, the second adjusting plate 13 is rotated to change the relative position between the second adjusting plate and the positioning plate 8, and the shielding plates 14 of the first adjusting plate and the second adjusting plate can change the size of the water passing groove hole 15, so that the adjustment of the water inlet flow is realized, the size of the first acting force is adjusted, and the flow of the water outlet 6 is ensured to be constant. The positioning rod is arranged, so that the second adjusting plate 13 can rotate relative to the slipknot 10, the guide sleeve 1 and the guide sealing sleeve 2. The edge of the outer side wall of the second adjusting plate 13 slightly protrudes out of the edge of the outer side wall of the slip joint 10, so that the slip joint 10 is convenient to adjust and attractive in appearance.

The lower part of the valve clack 3 is connected with the guide sleeve 1 in a sliding way, one part of the diaphragm 4 is sleeved outside the guide sleeve 1, the other part of the diaphragm 4 is sleeved outside the valve clack 3, and the diaphragm 4 between the outer side of the valve clack 3 and the outer side of the guide sleeve 1 is folded and then positioned inside the guide sleeve 1 along with the valve clack 3. When the valve clack 3 gradually moves out of the guide sleeve 1, the diaphragm 4 is driven to move along with the valve clack. The arrangement of the placement mode of the membrane 4 ensures that when the valve clack 3 moves, water is always separated inside the valve clack 3 and the guide sealing sleeve 2, and the flow regulation effect is further ensured.

One end of the spring 5 is connected with the moving groove 9 above the valve clack 3, the other end of the spring is connected with the top of the guide sealing sleeve 2, and the diameter of the upper part of the guide sealing sleeve 2 is gradually reduced from bottom to top. The shape of the upper part of the guide sealing sleeve 2 is arranged to ensure that water can smoothly enter the upper part of the slipknot 10.

The valve clack 3 is provided with a water through hole 12 communicated with the flow adjusting plate 7, the flow adjusting plate 7 is provided with a water inlet 11 communicated with the positioning plate 8, and the area of a shielding plate 14 of the positioning plate 8 is larger than that of a shielding plate 14 on the second adjusting plate 13. The area of the shielding plate 14 on the positioning plate 8 and the area of the shielding plate 14 of the second adjusting plate 13 are set, so that the adjusting range of the flow of the water inlet 11 is enlarged but the water inlet is not closed, and the difference value between the first acting force and the second acting force is controllable.

The upper part of the valve clack 3 is matched with the diameter of the guide sealing sleeve 2 at the water outlet 6, and the water outlet 6 is communicated with the slipknot 10. The diameter of the upper part of the valve clack 3 ensures the covering effect of the valve clack 3 on the water outlet 6 when driving the membrane 4 to move.

The lower part of the guide sealing sleeve 2 is connected with the side wall of the slipknot 10, a sealing ring is arranged between the guide sealing sleeve 2 and the side wall of the slipknot 10, and a sealing ring is arranged between the guide sleeve 1 and the guide sealing sleeve 2. The diameter of the lower part of the guide sealing sleeve 2 is arranged to ensure that water can only enter the upper part of the slipknot 10 along the water inlet 11 and the water outlet 6.

The center of the valve clack 3 is provided with an installation ring groove connected with the membrane 4, and the outer edge of the water passing groove hole 15 is flush with the inner edge of the guide sleeve 1. The area of the side wall of the guide sealing sleeve 2 penetrating through the through hole is smaller than that of the through hole, and smooth rotation of the second adjusting plate 13 is guaranteed.

When the water heater is used, the upper end and the lower end of the slipknot 10 are communicated with a heating pipeline, water enters the water through hole 12 along the water inlet 11 and finally moves to the position above the slipknot 10 from the water outlet 6. The change of the pressure below the slipknot 10, after interacting with the spring 5, enables the valve clack 3 and the membrane 4 to move up and down, and covers the water outlet 6 to different degrees.

When the water flow at the water inlet 11 is increased, the second adjusting plate 13 is rotated to adjust the water inlet flow at the water inlet 11.

Therefore, the utility model adopts the above structure a be applied to the constant flow slipknot of family with heating system, save installation space, effectively solve the unbalanced problem of flow distribution between each hot user.

Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention and not to limit the same, and although the present invention is described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that: the technical solution of the present invention can still be modified or replaced by other equivalent means, and the modified technical solution can not be separated from the spirit and scope of the technical solution of the present invention.
