Abstract
The utility model disclose a safe automatic exhaust valve, which includes a valve body, a knob, a spring, a thimble, an exhaust mouth and an exhaust knee pipe. One end in the valve body is a knee pipe chamber, and the other end is a thimble chamber. The knee pipe chamber and the thimble chamber are interpenetrated and are provided with a shrinkage exhaust port. One end of the exhaust knee pipe is inserted in the knee pipe chamber, and the inner wall of the knee pipe chamber and the outer wall of the exhaust knee pipe are fixed with a seal ring. One end of the thimble is a conical, and the conical position of the thimble resist the exhaust port between the knee pipe chamber and the thimble chamber. One end of the knob is inserted in the thimble chamber, and the knob is connected with the inner wall of the thimble chamber through a thread. A spring is arranged between the thimble and the knob, and the two ends of the spring resist the thimble and the knob respectively. The lower end of the thimble chamber positioned between the thimble and the knob is provided with an exhaust mouth hole which is arranged on the lower end of the valve body, and the upper end of the exhaust mouth is fixedly connected with the exhaust mouth hole. The utility model has the advantages of small volume, simple structure, low manufacturing cost, convenient operation, and safe and reliable, etc.
Description
(1) technical field:
The utility model relates to a kind of automatic control pressure vent, but particularly a kind of outlet valve that is arranged on automatic vent pressure on the radiator.
(2) background technique:
Along with the national economy of China constantly increases, living standards of the people improve a lot, and people are more comfortable, warm to the environmental requirement of oneself living.Very cold winter in the northern area of China, at the indoor installing heating equipment that needs.In building, urban residential building or places such as factory building, market, the overwhelming majority is the installing radiator at present, by the unified heating of boiler room manufacture hot water.Yet, in some small towns or rural area, unified heating equipment, most furnaces that use oneself heating are commonly called as native heating installation, this furnace be adopt to the water in stove or the cooking stove double wall heat with radiator in water carry out thermal cycle.Because furnace when the water in the furnace wall is heated, produces air pressure in the furnace wall and in the radiator, if untimely row pressure meeting causes the radiator explosion to cause casualty accident or damage product.At present, the exhaust pressure device on the employed radiator all is to utilize the outlet valve of screwing manually, when using this outlet valve, can't grasp the exhaust pressure time, and, in case forget exhaust pressure, will cause unnecessary harm.
(3) summary of the invention:
The technical problems to be solved in the utility model provides a kind of safe and reliable, when the air pressure that produces in radiator reaches setting value, and can self-bleeding safe automatic control pressure vent.
Safe automatic control pressure vent, comprise valve body, turn-knob, spring, thimble, exhaust nozzle and exhaust curved tube, end in the valve body is the curved tube chamber, its the other end is the thimble chamber, between curved tube chamber and thimble chamber, connect to be provided with and shrink the shape relief opening, an end of valve body and be positioned on the outer wall of curved tube chamber outside thread is arranged.It is indoor that one end of exhaust curved tube is plugged in curved tube, and be fixed with seal ring between the outer wall of the inwall of curved tube chamber and exhaust curved tube.It is indoor that thimble is arranged on thimble, and an end of thimble is conical, and the conical position of thimble replaces in the relief opening between thimble chamber and curved tube chamber, and relief opening is sealed, and gas or liquid can not be discharged.It is indoor that one end of turn-knob is plugged in thimble, and the inwall of turn-knob and thimble chamber to be to be threaded, and spring is arranged between thimble and the turn-knob, and the two ends of spring are replaced respectively on thimble and turn-knob.Be provided with the exhaust nozzle hole on the lower end surface of thimble chamber and between thimble and turn-knob, exhaust nozzle is arranged on the lower end of valve body, fixedlys connected with the exhaust nozzle hole in the upper end of exhaust nozzle.
During installation, in the exhaust curved tube insertion radiator with the utility model one end, the outer wall of valve body is connected with the radiator thread seal, and the exhaust nozzle on the valve body is provided with down.In use, the degree (just according to the air pressure size in furnace and the radiator) that can burn according to what or furnace of radiator is adjusted turn-knob, and the change spring is replaced the intensity on thimble, reaches the safety value of setting.In addition, in the time of before furnace uses, need adding water, can adjust turn-knob and make that spring is inelastic to be replaced on thimble, treat that air in the radiator is all discharged after, the adjustment turn-knob can guarantee safe heating.
The utlity model has that volume is little, simple in structure, low cost of manufacture, advantage such as esy to use, safe and reliable.
(4) description of drawings:
Fig. 1 is a kind of embodiment's schematic appearance of the utility model, and Fig. 2 is the cut-away view of Fig. 1, and Fig. 3 is the valve body structure schematic representation.
(5) embodiment:
Safe automatic control pressure vent, comprise valve body 1, turn-knob 2, spring 3, thimble 4, exhaust nozzle 5 and exhaust curved tube 6, one end of valve body 1 inside is curved tube chamber 7, and the other end of valve body 1 inside is thimble chamber 8, connects to be provided with between curved tube chamber 7 and thimble chamber 8 to shrink shape relief opening 9.One end of valve body 1 and be positioned on the outer wall of curved tube chamber 7 outside thread is arranged.One end of exhaust curved tube 6 is plugged in the curved tube chamber 7, and is fixed with seal ring 10 between the outer wall of the inwall of curved tube chamber 7 and exhaust curved tube 6.Thimble 4 is arranged in the thimble chamber 8, and an end of thimble 4 is conical, and the conical position of thimble 4 replaces in the relief opening 9 between thimble chamber 8 and curved tube chamber 7, and relief opening 9 is sealed, and gas or liquid can not be discharged.Spring 3 is arranged between thimble 4 and the turn-knob 2, and the two ends of spring 3 are replaced respectively on thimble 4 and turn-knob 2, and the front end of turn-knob 2 is plugged in the thimble chamber 8, and the inwall of turn-knob 2 and thimble chamber 8 is to be threaded.Be provided with exhaust nozzle hole 11 on the lower end surface of thimble chamber 8 and between thimble 4 and turn-knob 2, exhaust nozzle 5 is arranged on the lower end of valve body 1, and the upper end of exhaust nozzle 5 and exhaust nozzle hole 11 are to be threaded.
