Abstract
The utility model discloses an automatic water control valve, comprising an upper valve case, a lower valve case, a pressure adjusting nut, a compression spring, a stud with cone-shaped bottom, a tensile membrane, a sheet steel, a tap water inlet, a water tank connecting port, a switching pliofilm, an internal bladder core seat and a sealing ring; wherein, the bottom surface of the internal bladder core seat is provided with a water outlet; the cone-shaped-bottom stud is fixed with the tensile membrane through the nut after getting through the water inlet in the middle of the internal bladder core seat; a piece of sheet steel is underlaid at the connection between the tensile membrane and the cone-shaped-bottom stud and at the top and bottom of the tensile membrane each to clamp the tensile membrane to make the connection between the tensile membrane and the cone-shaped-bottom stud stabler to prevent the cone-shaped-bottom stud from sliding during vertical movement so as to strengthen the sealing performance at the threading position of the tensile membrane. Meanwhile, two pieces of the sheet steel can make the cone-shaped-bottom stud bear bigger acting force for more tightness during closing without any water or air leakage.
Description
Technical field the utility model relates to a kind of especially automatic water control valve door of using of the upper and lower water management of solar water heater of all kinds of water tanks, water tower that is applicable to.
The automatic water control valve door of background technique is used to realize water tank, the water tower particularly interior Shang Shui of solar water heater water tank, the automatic control of water down.But owing to directly wear fixing between conical bottom double-screw bolt (being spool) in existing its internal structure of this series products and tension force diaphragm with nut, when tension force diaphragm pulling conical bottom double-screw bolt moves up and down, be easy to generate slippage between conical bottom double-screw bolt and tension force diaphragm, thereby cause the tension force diaphragm to wear the sealing variation at place, hole, leak, gas leak phenomenon, influence the normal use of valve.In addition, generally be designed to the chamfering shape around the central through bore of switch glued membrane in the existing automatic water control valve door, the mode that opens and closes with internal-expansion type cooperates with the inner bag core print seat, reaches the control effect of water down.But in its course of action, often be difficult between switch glued membrane and inner bag core print seat aim at fully, thereby also can cause the generation of water leakage phenomenon.
Airtightly cooperate, can not leak and the automatic water control valve door of gas leak phenomenon fully between the good airproof performance, switch glued membrane that the summary of the invention technical problem to be solved in the utility model is to propose a kind of tension force diaphragm and inner bag core print seat.
For solving the problems of the technologies described above, the automatic water control valve door of the utility model comprises shell on the valve body, the valve body lower casing, look nut, stage clip, the conical bottom double-screw bolt, the tension force diaphragm, steel disc, the tap water water intake, the water tank connection mouth, the switch glued membrane, inner bag core print seat and seal ring, the bottom plane of described inner bag core print seat is provided with drainage hole, after described conical bottom double-screw bolt passes the middle water inlet of described inner bag core print seat, and wear by nut between described tension force diaphragm and be fixed together, in the joint of described tension force diaphragm and conical bottom double-screw bolt, on the described tension force diaphragm, following both sides respectively are lined with a described steel disc.
Above-mentioned automatic water control valve door, the outer rim of described switch glued membrane intermediate throughholes is special soft plain film, on the lower end surface of described inner bag core print seat, be provided with convex tendon along the outer of its water inlet.
Owing to adopted above-mentioned technical pattern, two steel discs that the upper and lower both sides of tension force diaphragm pad is established clamp the tension force diaphragm, make between tension force diaphragm and conical bottom double-screw bolt be connected more firm, the conical bottom double-screw bolt just can not produce sliding phenomenon when moving up and down, thereby strengthened the sealability that the tension force diaphragm wears the place.The use of two steel discs also makes the conical bottom screw can bear bigger active force, and it is tight to close Shi Nenggeng, thereby can not leak, gas leak phenomenon.In addition, during water inlet, under the effect of hydraulic pressure, special soft plain film in the middle of the switch glued membrane and the convex tendon on the inner bag core print seat lower end surface can fully closely fit together, change linear contact into by original interior distending enclosed between the two, make better tightness, thereby just water leakage phenomenon can not take place.
Description of drawings is described in further detail the utility model below in conjunction with drawings and embodiments.
Fig. 1 is the structural representation of the automatic water control valve door of the utility model.
Embodiment as shown in the figure, automatically the water control valve door comprises on shell 2 on cap 1, the valve body, valve body lower casing 3, look nut 4, stage clip 5, conical bottom double-screw bolt 6, tension force diaphragm 11, the stainless steel steel disc 10, tap water water intake 20, water tank connection mouth 21, switch glued membrane 18, inner bag core print seat 22, core print seat water inlet seal ring 12 and O-ring seals 17 under steel disc 9, the stainless steel, cap 1 is provided with pore 13, and 3 of shell 2 and valve body lower casings are fixed together by screw 19 on the valve body.The bottom plane of inner bag core print seat 22 is provided with drainage hole 15, and after conical bottom double-screw bolt 6 passes water inlet 14 on the inner bag core print seat 22, and 11 on tension force diaphragm wears by nut 8 and is fixed together.On the stainless steel under steel disc 9 and the stainless steel steel disc 10 fill up the upper and lower both sides that are located at tension force diaphragm 11 respectively.The outer rim of switch glued membrane 18 intermediate throughholes is special soft plain films, is provided with a circle convex tendon 16 on the lower end surface of inner bag core print seat 22, along the outer of its water inlet.Shell 2 and valve body lower casing 3 adopt nylon material to make on the valve body.When last water conservancy project was done, tap water was from water intake 20 water inlets.At this moment, under the effect of hydraulic pressure, switch glued membrane 18 up involution is lived the convex tendon 16 of inner bag core print seat 22, tap water passes from the intermediate throughholes of switch glued membrane 18, pass the water inlet 14 of inner bag core print seat 22 again, side direction enters in the water tank connection mouth 21 arrival water tanks again, makes water on the water tank.Along with the rising of water level, the hydraulic pressure in the valve body also increases gradually.Under the effect of hydraulic pressure, tension force diaphragm 11 up moves, and drives conical bottom double-screw bolt 6 and also up carries, when in water tank, reaching the water level that presets, hydraulic pressure makes conical bottom double-screw bolt 6 and core print seat water inlet seal ring 12 tight closure, stops in the water tank going up water, and valve has just played the effect that automatic control is closed.When needing water, open water tap, the pressure in the valve body reduces quickly, and under the effect of spring restoring force, tension force diaphragm 11 falls after rise, and conical bottom double-screw bolt 6 separates with core print seat water inlet seal ring 12, and water is toward dirty.Simultaneously, the last top active force that tap water acts on switch glued membrane 18 disappears, 18 resiliences of switch glued membrane, and the water in the water tank flows out by the intermediate throughholes that drainage hole 15 is pooled to switch glued membrane 18, and water-outlet quantity is big.Look nut 4 and stage clip 5 can be according to tap water pressure different, height of water level in the regulating tank.Down tune and press nut 4, the water level in the water tank increases, otherwise then the water level in the water tank reduces.
