Description

Interior two heating thermostatic valves of transferring

Two heating thermostatic valves of transferring belong to five metals hot-water heating valve manufacturing in a kind of, more precisely can be in certain temperature range A.T.C, and can be manually opened, the thermostatic valve that the radiator of cutting out uses.

Existing Winter heat supply system, except that a total valve is installed at the place of registering one's residence, it is exactly import and export at each group radiator, a stop valve is installed respectively, this two places stop valve uses when being used to keep in repair radiator, and can not use as regulating radiator temperature, therefore no matter ambient temperature how, the user can only accept the heat that heat supply company is provided passively, some users wish the room temperature height a bit in the real life, and other users wish that room temperature is too not high, and especially uninhabited place can be stopped using, but because radiator is unadjustable, therefore " heat " waste is serious.Because the warm mode of giving of single-main distribution that needs of development will be substituted by two-pipe system, it is very essential therefore developing the heating thermostatic valve.

Calendar year 2001, the patent No. was that 01229727 heating is with having proposed a kind of thermostatic valve that utilizes marmem as control unit in the thermostatic valve, a brand-new design is provided, but the inventor thinks in the actual use that it can't proper functioning, its reason is because marmem is inserted on the piston sleeve of valve, because piston is with higher temperature during work, therefore marmem is experienced is temperature on the piston sleeve, and can't experience indoor environment temperature, therefore this design can't really be worked automatically, if can enough temperature control this valve working, also just under the bigger situation of the temperature difference.The patent No. is the heating thermostatic valve of 01260069 can regulate temperature, on the top of valve an adjusting knob is arranged, and the pressure that is used for regulating marmem is used for controlling temperature, but it is subjected to piston sleeve temperature effect cisco unity malfunction because of marmem equally.

If marmem is positioned over the outside of piston sleeve, to reduce the temperature effect that piston sleeve produces undoubtedly, but because the temperature difference between distending of shape memory alloy material own and the contraction is bigger, therefore also to regulate the pressure of bias spring during except the deformation length of regulating marmem to marmem, control with this temperature required, may be more better.

The purpose of this utility model, just provide a kind of inlet/outlet place that is installed in radiator, regulate the automatic constant temperature valve of temperature in the certain temperature range, the temperature, pressure of the marmem in not only can modulating valve when regulating, simultaneously also can regulate the pressure of bias spring, to satisfy the purpose that require constant room temperature of user according to oneself to marmem.

The technical solution of the utility model is achieved like this, it is to utilize new material, the marmem characteristic, and make spring-like, when ambient temperature reaches the deformation temperature of marmem, marmem begins to expand and drives outer magnetic ring and does relative displacement, the relative displacement of outer magnetic ring by the magnetic line of force, drives the inside magnet column displacement in the valve, thereby cause the action of mechanism in a series of water valve, reach the purpose of closed and Open valve.Outer magnetic ring is to be installed on the piston sleeve, put in the lower piston of outer magnetic ring bias spring is installed, be used for after temperature cooling back marmem shrinks outer magnetic ring upwards being lifted, thereby open water valve, do for solving the too high malfunction that influences marmem of piston sleeve temperature, between outer magnetic ring and the marmem sheath is arranged, a compressing tablet that has three-jaw that can move up and down is arranged on the sheath.In order to regulate the expansion length of marmem, upper design has the adjusting gland of band Luo line, height with compressing tablet is controlled marmem, in order to control temperature better, in the bottom of bias spring a spring abutment that can move up and down by the handle rotation is arranged, the high and low bias spring that makes naturally of spring abutment changes to the pressure of marmem, comes the unlatching size of control valve with this, control temperature simultaneously, on piston sleeve, had a sign circle to be used for proofreading and correct temperature required.

Figure of description is that the heating of interior two accent is cutd open schematic diagram with the side of thermostatic valve: each sequence number is among the figure: valve body 1, big piston assembly 2, piston sleeve 3, marker loop 4, rubber column 5, locating stud 6, spring abutment 7, bias spring 8, inside magnet column 9, outer magnetic ring 10, compressing tablet 11, memory alloy 12, adjusting gland 13, handle 14, location mother Luo 15.

Embodiment: at first with inside magnet column 9, rubber column 5 and big piston assembly 2 are put into the inner chamber of piston sleeve 3 successively, one then spins piston sleeve 3 and valve body 1, after spring abutment 7 being inserted in the bottom of piston sleeve 3 bias spring 8 is inserted in piston sleeve 3, the top of spring abutment 7, be inserted in outer magnetic ring 10 then, the compressing tablet 11 that will have three-jaw, push down outer magnetic ring 10, marmem 12 is put in the top of compressing tablet 11, the bottom corresponding position of marker loop 4 with piston sleeve 3 joined, to have the handle 14 of regulating gland 13 at last entangles piston sleeve 2 and each relevant accessory thereof from top to bottom together, adjusting gland 13 in the handle 14 is joined, at last with location mother Luo 15 with marmem 12.Handle 14 is fixing.So far twoly in transfer heating to finish with the thermostatic valve assembling, in use because bias spring 8 upwards promotes outer magnetic ring 10 all the time, make top that outer magnetic ring 10 is in piston sleeve 3 to the inside magnet column 9 that begins, also be in the top of piston sleeve 3, whole valve body is in opening state.Marmem 12 beginning deformation owing to the reason marmem 12 of regulating gland 13 can only promote downwards, promote compressing tablet 11 downwards when temperature raises, because compressing tablet 11 joins with outer magnetic ring 10, therefore, outer magnetic ring 10 together moves down, and has compressed bias spring 8 and has made its contraction.Inside magnet column 9 moves down together also that to moving down, valve is in close valve state together with rubber column 5, big piston assembly 2 under the influence of the magnetic line of force of outer magnetic ring 10.When needs are adjusted temperature, handle with sleeve 14, because of handle 14 with regulate gland 13 Luo lines and be connected and regulate gland 13 and can not rotate by the influence on the top of piston sleeve 3, so handle with sleeve 14, regulating gland can only move up and down, and compresses or loosens pressure to marmem 12, has therefore changed the position of outer magnetic ring 10, simultaneously marmem 12 is in the pressure of different temperatures, when handle with sleeve 14 because the influencing spring abutment 7 and can only move up and down of location Luo silk 6.When spring abutment 7 moves up with bias spring 8, upwards promote, bias spring loosened when spring abutment 7 moved down, because bias spring 7 is by the variation in pressure of 10 pairs of memory alloys 12 of outer magnetic ring, therefore can obtain the Push And Release of different temperatures control valve, because the motive force of memory alloy changes along with temperature variation, when bias spring 7 makes progress the Driving force increasing, the thrust that memory alloy also just needs higher temperature bias spring could be made progress overcomes, throttle down, on the contrary marmem 12 is downward when the strength that bias spring 8 makes progress reduces, and the strength that promotes outer magnetic ring 10 also reduces with regard to corresponding, do not need higher temperature, make its deformation.The utility model utilizes marmem exactly, and deformation produces thrust with variation of temperature, the big more characteristics of the high more deformational stress of simultaneous temperature, and the stress of 7 pairs of marmems 12 of change bias spring makes valve can automatically control unlatching.Facts have proved that it is reliable, accurately, utilize the diverse location of adjusting gland 13 in the handle 14 and spring abutment 7 to come the temperature deformation and the stress of shape transformation memory alloy 12, the deformation length that more only changes marmem is more scientific and reasonable.
