Abstract
The utility model discloses a thermostat automatic inflow valve, comprising a valve body, a valve seat and a valve core, wherein the valve core is provided with a valve rod, and the valve rod is provided with a sealing ring and a gland. The end of the valve rod has a groove, in which one side of the adjusting rod is arranged, and the other side extends and is fixed on the upper end cover of the valve body. The cover is provided with a screw sealing ring, and a pressure spring is arranged between the gland and the ring washer. The outlet of the valve body is provided with a baffle and a hole for water. The heat expansion bend is arranged at the baffle and the exhalant canal, and is corresponding to the valve rod which extends from the valve seat, adjusting the valve for the purpose of temperature control. The utility model is characterized by simple structure, convenient operation and installation, low manufacturing cost and continual inflow.
Description
The utility model relates to a kind of automatic water inlet valve, and particularly a kind of expansion principle of utilizing realizes the temperature control automatic water inlet valve of water inlet automatically on solar water heater.
The prior solar water heater automatic water inlet valve generally adopts Floating Ball Liquid Level Control valve or electromagnetic induction control inlet valve at present.The Floating Ball Liquid Level Control valve is controlled water inlet by the liquid level of ball float in water storage box, and its shortcoming is to open the mounting hole of an installation and control valve on the position of water storage box correspondence, and volume is big, cost is high, can not intake continuously.Electromagnetic induction control inlet valve is by being installed in the sense cell control electromagnetic valve water inlet in the water storage box, its shortcoming is to connect signaling line, for solenoid valve provides power supply, it is loaded down with trivial details to go between, original dwelling house is installed difficult especially, signaling line, the open-air installation easily of power line are worn out, and have unsafe factor, and the cost height.
For overcoming the problem of above-mentioned existence, the purpose of this utility model just provides a kind of simple in structure, easy to install, the temperature control automatic water inlet valve that can intake continuously.
For achieving the above object, a kind of temperature control automatic water inlet valve of the present utility model, comprise valve body, valve seat, spool, valve body is provided with intake tunnel and exhalant canal, valve seat is arranged on the exhalant canal of valve body, described spool is provided with adjustable valve rod, valve stem packing ring and sealing gland are set on the valve rod, the end of valve rod has groove, adjusting screw rod one end is arranged in the groove of valve rod, the other end stretches out and is fixed on the valve body upper end cap, is provided with the screw rod seal ring in the end cap, at gland and be arranged between the ring washer on the adjusting screw rod and be provided with holddown spring; The outlet of valve body is provided with baffle plate, and hot expansion bend is arranged on baffle plate center hole and the exhalant canal, corresponding with the valve rod that stretches out valve seat, and the baffle plate periphery has osculum.
Described valve seat is provided with seal washer.Described spool is provided with valve core seal ring.Described valve core seal ring is provided with the clamping back-up ring.Between spool and valve body, be provided with fixing pin.
The utility model is owing to be provided with adjustable valve rod on spool, valve stem packing ring and sealing gland are set on the valve rod, the end of valve rod has groove, be arranged on the adjusting screw rod can regulate valve rod on the end cap, the outlet of valve body is provided with baffle plate, and hot expansion bend is arranged on baffle plate center hole and the exhalant canal, corresponding with the valve rod that stretches out valve seat, and the baffle plate periphery has osculum, regulating valve stem is the aperture of can regulate inlet valve, thereby reaches control water storage box temperature; Have advantages such as simple in structure, easy to install, that cost is low, can intake continuously.
Below in conjunction with the drawings and the specific embodiments the utility model is described in further detail.
Fig. 1 is a structural representation of the present utility model.
Shown in Figure 1, a kind of temperature control automatic water inlet valve of the present utility model comprises valve body 2, valve seat 15, spool 6, and valve body 2 is provided with intake tunnel 16 and exhalant canal 17, and valve seat 15 is arranged on the exhalant canal 17 of valve body 2, and fixing with valve body 2 by seal washer 3; Be provided with valve rod 10 in the spool 6 with threaded adjusting, valve stem packing ring 7 and sealing gland 9 are set on the valve rod 10, the end of valve rod 10 has groove 19, adjusting screw rod 12 1 ends are arranged in the groove 19 of valve rod 10, the other end stretches out end cap 14, end cap 14 is fixed on the valve body 2, is provided with screw rod seal ring 13 in the end cap 14, makes adjusting screw rod 12 and end cap be in sealing; At gland 9 and be arranged between the ring washer 20 on the adjusting screw rod 12 and be provided with holddown spring 11, guarantee spool 6 and valve rod 10 sealings; The outlet of valve body 2 is provided with baffle plate 18, hot expansion bend 1 is arranged on baffle plate 18 center holes 22 and the exhalant canal 17, corresponding with the valve rod 10 that stretches out valve seat 15, the expansion position of hot expansion bend 1 is greater than center hole 22, hot expansion bend 1 is in the exhalant canal 17 all the time, and baffle plate 18 peripheries have osculum 21.When the water temperature in the water storage box meets and exceeds setting value, because thermal expansion makes hot expansion bend 1 distortion produce thrust, jack-up valve rod 10, valve rod 10 drives spool 6, makes valve be in into water state.The aperture of valve is corresponding with the temperature of water storage box, and the high more valve opening of temperature is big more, and inflow is also big more, vice versa.In the time will adjusting the setting temperature of water storage box, only need to regulate adjusting screw rod 12 adjusting screw rods 12 and drive valve rod 10 along spool 6 rotations, the distance that changes between valve rod 10 and the hot expansion bend 1 gets final product.
For guaranteeing the sealing effect between valve seat 15 and the spool 6, the periphery on spool 6 is provided with valve core seal ring 4.Softening for preventing valve core seal ring 4, reduce sealability, on valve core seal ring 4, be provided with and clamp back-up ring 5.For preventing that spool 6 from following adjusting screw rod and rotating, between spool 6 and valve body 2, be provided with fixing pin 8.
