It is provided with flap, connecting shaft, axle sleeve, valve rod and handwheel, wherein, in described axle sleeve, is provided with spring, institute
Stating that connecting shaft and described spring are fixing to be connected, described body base is respectively equipped with water inlet and outlet two
Individual mouth, is circumferentially with U-shaped groove in described valve body, be provided with electric heating tube in groove, and described groove leads to
Crossing after stainless steel gasket embeds through welded seal molding, described valve body wall is provided with temperature probe, described
Temperature probe is connected with temperature controller, power supply and electric heating tube successively, during use, utilizes temperature control
Device processed sets the temperature range 5 30 DEG C of electric heating tube work in advance, when, after power on, thermometric is visited
Head by the Temperature Feedback of body cavity that real-time detects to temperature controller, when temperature is less than 5 DEG C,
Electric heating tube automatically begins to heated at constant temperature, and outlet valve inner chamber is brought rapidly up, such as body cavity in heating process
Temperature higher than 30 DEG C, then temperature controller controls electric heating tube and stops heating, to keep the flap can be free
Move up and down.
Used in fire-fighting handwheel heating temperature control outlet valve, wherein, described power supply can use fire fighting truck interior certainly
Charged.
Used in fire-fighting handwheel heating temperature control outlet valve, wherein, two interfaces of described electric heating tube and high temperature
Wire bonding connects, one layer of protective jacket of described higher temperature line outer cladding.
Used in fire-fighting handwheel heating temperature control outlet valve, wherein, described flap is slab construction.
The invention have the benefit that
1. outlet valve opens flap by rotation hand wheel band ovable valve stem, is provided with spring in axle sleeve simultaneously,
Outlet valve low pressure seal and secondary opening can be ensure that according to the unlatching pressure of pressure requirements adjustment flap, as
Can the minimum operating pressures that of spring be adjusted to 8kg, when hydraulic pressure is less than 8kg, in outlet valve, flap is not
Can open water outlet, only when hydraulic pressure is more than 8kg, flap just can slowly rise, and now valve slowly goes out
Water, it is to avoid quickly open as ball valve and to cause hose coupling to fly out, it is ensured that the life peace of fireman
Entirely.
2. it is provided with electric heating tube in valve body, and is connected with temperature controller, temperature probe, can be real-time
Monitor the temperature of body cavity, it is to avoid the water remained in outlet valve when being badly in need of using is because of the too low icing of temperature
Make flap to open, cause equipment to damage or impact rescue, it is ensured that can be normal when using in the scene of a fire
Water outlet, ensure that the safety of people's life and property greatly, and this device can be with fire fighting truck simultaneously
Interior portable power source connects use, more convenient, mobility strong, saves the energy, more safe and reliable.
Accompanying drawing explanation
Fig. 1 is the sectional view of the present invention
Fig. 2 is the sectional drawing of A-A of the present invention
Detailed description of the invention
A kind of used in fire-fighting handwheel heating temperature control outlet valve as shown in the figure, including the valve body 1 of hollow, valve body 1
It is sequentially provided with flap 2, connecting shaft 3, axle sleeve 4, valve rod 5 and handwheel 6, described valve the most from bottom to top
Lobe 2 is slab construction, is provided with spring 7, is respectively equipped with bottom described valve body 1 in described axle sleeve 4
Water inlet 8 and outlet 9 two mouth, be circumferentially with U-shaped groove 10, groove 10 in described valve body 1
Inside being provided with electric heating tube 11,11 two interfaces of described electric heating tube are welded to connect with higher temperature line 18, institute
The one layer of protective jacket 19 of higher temperature line 18 outer cladding stated, described groove 10 is embedded by stainless steel gasket 12
