Abstract
The invention relates to a hand wheel heating temperature control water discharge valve for a fire fighting trunk. The hand wheel heating temperature control water discharge valve for the fire fighting trunk comprises a hollow valve body. The valve body is provided with a valve clack, a connecting shaft, a shaft sleeve, a valve rod and a hand wheel in sequence from bottom to top. A spring is arranged in the shaft sleeve. The connecting shaft is fixedly connected with the spring. A water inlet and a water outlet are respectively formed in the bottom of the valve body. A U-shaped groove is formed in the valve body in the circumferential direction. Multiple electric heating tubes are arranged in the groove. A stainless steel spacer is embedded in the groove and then the groove is formed in a welded and sealed mode. A temperature measurement probe is arranged on the wall of the valve body and connected with a temperature controller, a power source and an electric heating strip in sequence. The hand wheel heating temperature control water discharge valve for the fire fighting trunk can be automatically adjusted and controlled according to real-time temperature inside the water discharge valve, so that heating is conducted, the inner portion of the water discharge valve is prevented from being frozen, and use is convenient and safe.
Description
Technical field
The present invention relates to a kind of outlet valve, relate in particular to a kind of used in fire-fighting handwheel heating temperature control outlet valve.
Background technique
Along with socioeconomic fast development, the harm that fire causes to the mankind's lives and properties and lose increasing, fire-fighting truck is as the capital equipment of fire extinguishing, the quality of equipment quality directly has influence on efficiency and the success or failure of fire extinguishing, outlet valve, as used in fire-fighting critical component, is directly connected to the people's life safety.There is following defect in the outlet valve of used in fire-fighting at present:
1. what current known used in fire-fighting outlet valve was used is ball valve, because ball valve inner chamber more or less has Yu Shui, and the northern area of China very cold in winter, therefore it easily froze in winter, if firmly changeover valve easily damages seal ring in the time of need to using, and incur loss through delay fire-fighting and rescue opportunity, the people's lives and property is caused safely to heavy losses.
2. because fire fighter is more urgent when the responding, open valve speed, occur that sometimes hose coupling holds pressure that can't stand water outlet, cause hose coupling to fly out, damage to fire fighter's life safety.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of used in fire-fighting handwheel heating temperature control outlet valve, and it can heat according to the real time temperature auto-control of outlet valve inside, prevents outlet valve inner icing, easy to use, safer.
For solving the problems of the technologies described above, technological scheme of the present invention is:
Used in fire-fighting handwheel heating temperature control outlet valve, the valve body that comprises hollow, in valve body, be provided with successively flap from bottom to top, coupling shaft, axle sleeve, valve rod and handwheel, wherein, in described axle sleeve, be provided with spring, described coupling shaft is fixedly connected with described spring, described valve body bottom is respectively equipped with water inlet and two mouths of water outlet, in described valve body, be circumferentially with U-shaped groove, in groove, be provided with electric heating tube, described groove embeds by welded seal moulding by stainless steel gasket, described valve body wall is provided with temperature probe, described temperature probe successively with temperature controller, power supply is connected with electric heating tube, during use, utilize temperature controller to set in advance 5-30 ℃ of the temperature ranges of electric heating tube work, after power connection, temperature probe by the temperature feedback of the body cavity real-time detecting to temperature controller, when temperature is during lower than 5 ℃, electric heating tube starts heated at constant temperature automatically, outlet valve inner chamber heats up rapidly, if the temperature of body cavity in heating process is higher than 30 ℃, temperature controller control electric heating tube stops heating, to keep flap freely to move up and down.
Used in fire-fighting handwheel heating temperature control outlet valve, wherein, described power supply can adopt in fire-fighting truck self-powered.
Used in fire-fighting handwheel heating temperature control outlet valve, wherein, described two interfaces of electric heating tube and higher temperature line are welded to connect, described higher temperature line outer cladding one deck protecting cover.
Used in fire-fighting handwheel heating temperature control outlet valve, wherein, described flap is slab construction.
Beneficial effect of the present invention is:
1. outlet valve is opened flap by rotation hand wheel band ovable valve stem, in axle sleeve, be provided with spring simultaneously, can require the cracking pressure of adjusting flap to guarantee outlet valve low pressure seal and secondary opening according to pressure, as the minimum working pressure power of spring being adjusted to 8kg, when hydraulic pressure is less than 8kg, in outlet valve, flap can not opened water outlet, only have when hydraulic pressure is greater than 8kg, flap just can slowly rise, the now slow water outlet of valve, avoid quick opening as ball valve to cause hose coupling to fly out, guaranteed fireman's life safety.
2. in valve body, be provided with electric heating tube, and be connected with temperature controller, temperature probe, the temperature of monitor valve intracoelomic cavity in real time, while avoiding being badly in need of using, in outlet valve, residual water cannot open flap because of too low the freezing of temperature, cause equipment to damage or impact rescue, normally water outlet while guaranteeing to use in the scene of a fire, guaranteed greatly the safety of people's life and property, this device can be connected use with portable power source in fire-fighting truck simultaneously, more convenient, mobility strong, energy saving, more safe and reliable.
