Description
Technical field
The utility model is in the winter heating system, can be according to setting the valve of regulating heating temperature automatically.
Background technique
In prior art, 012297275,012600695 " heating thermostatic valve " (patent No. is:, application number 02245750X) is to use memory alloy as thermosensitive element, its basic principle is: produce deformation when the shape memory alloy spring temperature influence, make the permanent magnet rings in the actuator produce displacement, thereby drive piston assembly, the open degree of control valve body has promptly been controlled rate-of flow, reaches the purpose of regulating temperature.But the problem that this valve structurally exists: the one, single groove sliding motion structure handle of adjustment shape memory alloy spring position uses unsmooth, and the location is inaccurate, and precision is low, and feel is poor.Thermostat valve has been divided into four parts in the time of need dismantling, comprise valve body, magnet ring, spring, temperature sensing part (containing shell).Part is at random, loses easily.When assembling, magnet ring direction dress easily is anti-, can cause thermostat valve not work again.And maintenance, replacing component difficulty are installed in inconvenience.The 2nd, the combination of employed plastic cap and magnetic post in the thermostat valve piston assembly (the magnetic post is embedded in the plastic cap), be to embed bonding the forming in back, short time promptly comes off voluntarily in WATER AS FLOW MEDIUM, after coming off, make it, may be crooked, even direction puts upside down and cause valve not open, in addition The whole control malfunctioning, be in abnormal condition.
Summary of the invention
The utility model provides a kind of novel thermostat valve, solves that valve parts is at random, the scale handle rotates dumb, inconvenient maintenance and technical problem that plastic cap and combining of magnetic post come off easily voluntarily.
The technological scheme that the utility model thermostat valve is taked is: be combined with piston head, rubber pad and piston in valve body on the valve port, be socketed with valve rod on the piston, valve rod is built-in with the plastic cap that cooperates with piston and the magnetic post above the plastic cap, the magnet ring that valve rod is with spring outward and cooperates with the magnetic post, cover in the outer socket of magnet ring is regulated connects the memory alloy seat on the magnet ring, be with shape memory alloy spring on this seat, the cover outside connects the adjusting overcoat in above-mentioned adjusting, it is characterized in that:
This valve is to be connected by two independent parts splits of main valve body and temperature control head, by locknut the outside thread of temperature control head bottom with main valve body connected together, wherein valve rod and valve body are connected as a single entity becomes the main valve body part, the temperature control head part: cover is fixed in the base in regulating, the memory alloy spring seat is pegged graft with the interior cover of adjusting top, the outside thread of regulating the overcoat bottom is connected with the screw-internal thread fit of base, the upper end of regulating overcoat is connected with scale handle inner face, scale handle lower edge indicates scale, have dial window with respect to the base position, scale handle and base are slidingly connected;
There is open-work at above-mentioned magnetic post center, and plastic cap wraps in magnetic post appearance and the magnetic post is injected into one, and magnetic post bottom surface is left and revealed the hole.
Above-mentioned dew Kong Yousan.
The circumferential surface that above-mentioned plastic cap wraps in magnetic post appearance is a serrated face.
Beneficial effect: the moment that the utility model produces when transmitting the shape memory alloy spring plastic deformation by the coupling of ferromagnetic material, shape memory alloy spring is installed in the top of temperature control head, and deformation energy is passed to a magnet ring through base, magnet ring is to be enclosed within one can allow on its valve rod that slides up and down, can movable magnetic post and in valve rod, install one, and it is opposite with the magnetic of magnet ring, attract each other, when shape memory alloy spring generation plastic deformation, promote magnet ring, and drive the displacement of magnetic post.The magnetic post is connected with the interior piston of valve rod, drives piston and moves up and down, and reaches unlatching, regulate, and Shuttoff Valve, thus controlled rate-of flow.The combination of cover and base in this valve regulation, base is convenient to regulate temperature with multi-thread spiral being rotatably connected of regulating overcoat, and temperature adjustment accurate (± 1 ℃), rotate smoothly good hand touch, solid and reliable, rotation easily, have no card and bump sensation, make the scale handle by original moving up and down, change into cast, drive the adjusting overcoat and move up and down, regulated the position of shape memory alloy spring more reposefully.Magnet ring and spring are fixed in the base of temperature control head by cover in the adjusting, simultaneously, scale handle and base are slidingly connected at together with annular catching groove, form an integral body, form a temperature control head, this temperature control head bottom is connected through the valve body of locknut and high in and low out, forms complete thermostat valve.This thermostat valve is made up of temperature control head and valve body two-part, is convenient to install, dismantles and maintenance.
The utility model before the plastic cap molding and forming, is inserted magnetic post with holes used magnetic post in the mould in advance, and disposable notes are one, has solved the problem that magnetic post and plastic cap come off under aqueous medium soaks easily.
This thermostat valve can be allocated thermal resource automatically, improves indoor hot comfort, and energy-saving effect is remarkable.Through the practicality test, valve event is good, and action error is ± 1 ℃, and stable performance is reliable.Be mainly used in heating system and regulate the room temperature, divide family control, household metering.
