Abstract
The utility model relates to a scald preventing intelligent safety valve which is composed of an inner joint (1), a guide sleeve (5), an outer joint (10), a mechanical temperature sensing element (6), and springs (4, 8), wherein the guide sleeve (5), the temperature sensing element (6) and the springs (4, 8) are arranged in the space inside the joints; the inner joint is screwed into the outer joint, and both the inner and the outer joints are provided with a through hole (12); the guide sleeve which is supported on steps at one end of the joints supports one end of the mechanical temperature sensing element of a corrugated pipe, and the other end of the temperature sensing element of the corrugated pipe contacts the springs; the other end of the springs is arranged on the steps of the guide sleeve of the outer joint; a step-shaped interface exists between the end of the mechanical temperature sensing element of the corrugated pipe and the inner wall of the joints. When the temperature of scalded water exceeds a safety temperature, water flow is shut off automatically.
Description
The utility model relates to a kind of anti-scald intelligent safety valve, especially the anti-scald intelligent safety valve of water heater pipeline.
The water heater of electricity, combustion gas and solar energy (shower bath that comprises cold and hot two water inlets) often has during use or during improper use and scalds water and flow out, and the swelling of excessive temperature has can cause accident.It is necessary that anti-scald water is hurted sb.'s feelings, and does not see that yet simple in structure, respond well safe burn-proof device is arranged at present.
The purpose of this utility model is: a kind of anti-scald intelligent safety valve is provided, when the temperature of scalding water surpasses a certain safety temperature, safety valve can be automatically turn-offs current, and provides when the possible leakage of bellows heat responsive element, still has the anti-scald intelligent safety valve of good result.
The purpose of this utility model is achieved in that a kind of anti-scald intelligent safety valve, comprise spigot, socket, heat responsive element, the spigot guide pin bushing, spring is formed, guide pin bushing, the bellows heat responsive element, spring is inserted the space in the joint, be provided with between spigot and the socket and be threaded, spigot screws in socket, joint all has through hole, one end bearing of spigot guide pin bushing is on the step of joint edges, one end of guide pin bushing the other end supporting bellows heat responsive element, the other end of bellows heat responsive element contacts with pad, pad contacts with spring again, and this end of bellows heat responsive element and inner nosepiece wall have step-like space, and the spring the other end is fixed on the socket step.Above-mentioned spigot guide pin bushing can be the supporting member that and joint connect into an integral body.
Further improvement of the utility model is: in order to overcome the possible leakage of bellows heat responsive element, and can prevent still that when leaking scalding water hurts sb.'s feelings, the utility model is provided with the radial support spring on the spigot guide pin bushing, contact by flexible guide pin bushing supporting bellows heat responsive element and with another spring, and spigot guide pin bushing and inner nosepiece wall have step-like space.
Working principle of the present utility model is: when proper functioning, current flow to the joint the other end in the guide rod space of joint one end and through the space between bellows heat responsive element and the joint, and when water temperature surpasses a certain temperature, the temperature that for example generally may scald human body is 50-55 ℃, so far temperature bellows heat responsive element expands and moves, overcome the elasticity of spring, blocking this end of bellows heat responsive element and inner nosepiece wall has step-like space, and current are cut off.The utility model can be made a joint tube shape, is installed between water outlet halter and the intake pipe.Of the present utility modelly overcome the possible leakage of bellows heat responsive element and have anti-scald working principle and be: when the bellows heat responsive element leaks, bellows is then compressed by the guide pin bushing radial spring, then spigot guide pin bushing and inner nosepiece wall have step-like space to be closed, and have cut off current.As long as the user screwed off and took apart this moment, change the bellows heat responsive element and get final product.
Characteristics of the present utility model are: this is a kind of anti-scald intelligent safety valve, and when the temperature of scalding water surpassed a certain safety temperature, safety valve can turn-off current automatically, when the bellows heat responsive element may leak, still has good anti-scald effect.The utility model anti-scald effective, volume is little, simple in structure, be easy to installation and removal, can be supporting with the water heater of various electricity, combustion gas and solar energy.
The utility model is described in further detail below in conjunction with accompanying drawing and by embodiment:
Fig. 1 is the utility model cross section structure schematic representation
As shown in the figure, anti-scald intelligent safety valve, comprise spigot 1, socket 10, heat responsive element 6, spigot guide pin bushing 5, spring 4,8 form, guide pin bushing 5, heat responsive element is a bellows heat responsive element 6, spring 8 is inserted the space in the joint, be provided with between spigot and the socket and be threaded 11, also has O-ring seals 3 between the joint, spigot screws in socket, joint all has through hole 12, can be provided with connecting thread etc. on the joint, one end bearing of spigot guide pin bushing 5 also can form on the 1-1 of space at the step of joint edges, the spigot guide pin bushing is provided with radial support spring 4, one end of guide pin bushing the other end supporting bellows heat responsive element 6, and spigot guide pin bushing and inner nosepiece wall have step-like space; The other end of bellows heat responsive element contacts with spring 8, and flexible guide pin bushing supported the bellows heat responsive element and with another spring 8 Elastic Contact.This end of bellows heat responsive element and inner nosepiece wall have step-like space 8-1, and the spring the other end is fixed on the socket step 9, and 7 is a pad, also is used to support spring 8.There is space 5-1 to make joint through hole and inner nosepiece wall have step-like space 1-1 to be communicated with on the guide pin bushing wall.
