Embodiment
Below in conjunction with accompanying drawing, the utility model is further described.Following examples only for clearly the technical solution of the utility model being described, and can not limit protection domain of the present utility model with this.
A kind of anti-theft antifreezing valve, comprises valve body 2, the valve rod 1 be located in valve body 2, the valve gap 3 being positioned at valve body 2 upper end and separated type valve handle 4, also comprises freeze-proof heating system.
As shown in Figure 1, valve gap 3 hollow in the axial direction, valve rod 1 is through the hollow space of valve gap 3, and its upper-end surface flushes with valve gap 3 upper-end surface, valve rod 1 upper end inner hollow, valve gap 3 upper-end surface is provided with the cylindrical hole 15 of bottom lateral opening, is provided with steel ball 8 in cylindrical hole 15, the bottom of cylindrical hole 15 is provided with the opening be communicated with valve gap 3 hollow space, is just in time stuck in the centre of this perforate when steel ball 8 is positioned at bottom; Valve rod 1 is provided with annular groove 16 in the corresponding part of cylindrical hole 15 bottom end opening, and annular groove 16 is provided with the first permanent magnet 12 along stem shaft to centre; Second permanent magnet 7 corresponding and larger than the first permanent magnet 12 magnetic with cylindrical hole 15 position is provided with in valve handle 4.
As shown in Figure 2, valve gap 3 is provided with the bonnet 17 be connected with its spiral, and this bonnet 17 prevents from being caught in the rain for the protection of valve gap or foreign material enter.
When utilize valve handle 4 make annular groove 16 on valve rod 1 by rotate to cylindrical hole 15 bottom opening time, steel ball 8 is stuck between annular groove 16 and cylindrical hole 15 bottom end opening place, and the first permanent magnet 12 firmly holds steel ball 8, valve rod can not arbitrarily be rotated to move up and down, and plays anti-theft protection effect; When wanting rotary valve rod; open bonnet 17; valve handle 4 is put into vacancy, valve rod 1 upper end; because the magnetic of the second permanent magnet 7 in valve handle 4 is greater than the first permanent magnet 12; second permanent magnet 7 attracts steel ball 8 to move upward, and valve rod 1 does not limit by steel ball protection, now; rotate valve handle 4 and get final product rotary valve rod, opening/shutting valve.
Be provided with packing 13 in valve body 2, packing 13 is phenol formaldehyde foam or polystyrene foamed boards thermal insulating material.Packing 13 has elasticity and insulation effect, and when can prevent temperature from reducing rapidly, the water-cooled in valve body freezes expansion, causes valve body to burst.
Valve rod 1 is provided with seal washer 10 with described spool 6 and packing 13 joint respectively, prevents such as the water of the medium in valve body from overflowing outside valve rod 1.Seal valve seat 9 is also provided with, for coordinating throttle down with spool 6 in valve body 2.
As shown in Figures 3 and 4, valve handle cross section 14 and valve rod upper end cross section of inboard wall 18 shape of valve handle 4 are six prismatics or triangle, the area of valve handle cross section 14 is slightly less than the area of valve rod upper end cross section of inboard wall 18, the lower end aligned of valve handle 4 is put into valve rod 1 upper end hollow space, just rotatable valve rod.
The electro-heat equipment 5 that freeze-proof heating system comprises heating control device 11 and wraps at valve body 2 outer surface.Heating control device 11 comprises power supply and automatic heating controller, and power supply, automatic heating controller and electro-heat equipment 5 is electrically connected successively.
Electro-heat equipment 5 comprises in zonal distribution and is wrapped in resistance wire in ambroin or rubber, is wrapped in the surrounding layer outside resistance wire and is positioned at the heat responsive element of surrounding layer; Surrounding layer is phenol formaldehyde foam or polystyrene foamed boards thermal insulating material.
Power supply can be the battery pack of charging battery, Ac or solar electrical energy generation.
When the heat responsive element in surrounding layer detects valve body temperature lower than the low value set, as 1 °, automatic heating controller opens electro-heat equipment 5, heats to valve body 1, when temperature reaches the high level of setting, as 5 °, stop heating, and detect valve body temperature in real time, when temperature drops back is to low value, reheat, make valve body temperature remain between low value to high level in the process always, prevent valve bursting by freezing.
The present embodiment is normal closed gate, and namely when bonnet 17 is tightened with valve gap 3, valve is in closed condition; If valve needs often to open, then can by valve design for when bonnet 17 to be tightened with valve gap 3, valve is in opening state.
The utility model utilizes the annular groove 16 of the steel ball 8 in valve gap 3 cylindrical hole 15, valve rod 1 and the first permanent magnet 12 well to be protected in valve gap by valve rod, by the special valve handle 4 ability rotary valve rod 1 with the second permanent magnet 7, anti-theft function must be had; When temperature is lower, utilizes antifreeze heating equipment 11 automatically to open electro-heat equipment, prevent valve by bursting by freezing.The utility model is rational in infrastructure, simple and practical, has anti-theft antifreezing effect.
The above is only preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the prerequisite not departing from the utility model know-why; can also make some improvement and distortion, these improve and distortion also should be considered as protection domain of the present utility model.
