Description
Technical field
The self-supporting temperature-sensing valve that a kind of radiator is used belongs to the civil heating equipment technical field.
Technical background
In recent years, along with country to the going deep into of welfare heating policy reform, heating system is carried out branchs family note amount, the installation automatic temperature control valve has been trend of the times on radiator.But no matter existing automatic temperature-controlled valve technology is homemade, still external, all is to adopt temperature-sensing element (device) directly to drive piston to move up and down, and reaches the opening and closing of control valve, thereby reaches the purpose of control room temperature.But since temperature-sensing element (device) always do not stop along with variation of temperature, drive the motion that piston does not stop, the time one is long, between piston rod and the Sealing, because the wearing and tearing slit appears in constantly friction, finally causes thermal medium to leak outside.For example the somewhere is after installing this type of thermostat valve, large-area water leakage phenomenon just occurs less than 1 year, is exactly that this structural imperfection causes.
Summary of the invention
Purpose of the present invention provides the self-supporting temperature-sensing valve that a kind of medium can not leak outside.
The object of the present invention is achieved like this on the valve body top of enterprising, following water outlet, has the valve gap of a band cover, in the inner chamber of valve gap, a self-powering type spool, valve rod is arranged; Valve rod inserts in valve pocket in the sleeve pipe in the valve gap, and valve rod has a magnetic post, the outside of the sleeve pipe of valve gap in the upper end, be with a circle cover that can outside sleeve pipe, move up and down, in the circle cover magnet ring is arranged, moving up and down of magnet ring also moves up and down by magnetic cornice ovable valve stem; The outside of circle cover is with a reset spring, and drive link is withstood on the top of circle cover, and the top of drive link is connected with the temperature heat-sensitive element, and the temperature heat-sensitive element can be a thermometer bulb, also can be the shape-memory body; The temperature heat-sensitive element is installed in the regulating handle; Piston column is arranged in the spool, there is a relief hole inside of piston column, the upper shed of relief hole and valve gap internal upper part spatial communication, and can be covered by the sealing cover on the valve rod, the downside opening communicates with the water inlet of valve body, the upper and lower end of piston column is with rubber seal, and last seal ring is with valve inleting water mouth and valve gap internal upper part spatial separation, and lower seal can be with the water outlet shutoff on the valve body; Stem lower portion is passed the piston column inner chamber, and dynamically is connected with piston column by a rubber sleeve; When valve is in open mode, because the valve gap inner chamber equates that with water inlet, water outlet pressure valve rod and valve rod can move downward under external force.When if the ambient temperature around the thermostat valve rises, the temperature heat-sensitive element expands, the magnet ring that inflation process promotes in drive link and the circle cover moves downward, magnet ring promotes the magnetic post in the valve rod again, thereby driving valve rod moves downward, sealing cover on the valve rod immediately stops up piston column upper end relief hole, the lower seal of piston column when moving down with piston column with the water outlet shutoff on the valve body, valve closing or turn down.Because flowing to the thermal medium of radiator reduces, ambient temperature slowly descends, when temperature drops to the setting value of thermostat valve, the temperature heat-sensitive element shrinks, and under the effect of reset spring, valve rod begins to promote outside the circle cover, leave relief hole in a flash at sealing cover, intake pressure forces the valve gap chamber pressure consistent with discharge pressure through relief hole, and valve rod rises valve open under magnet ring drives.If there is not relief hole on the piston column, after valve closing, because the valve gap inner chamber must cause the supercharging of valve gap inner chamber at this moment along with the lifting of valve rod, magnet ring is difficult to drive valve rod and rises, and valve will not opened; Same principle valve if there is not relief hole, when valve rod moves down, will form negative pressure at the valve gap inner chamber under magnetic force in closing closed procedure, valve rod moves down difficulty, finally causes valve not close.Regulating handle can be regulated the pressurized degree of reset spring, thus the temperature when having set the unlatching of valve.
The invention has the beneficial effects as follows, because the piston column in the spool has relief hole, valve rod just can be under the effect of the restoring force of magnetic force and spring, moving up and down freely, valve can be opened or be closed thus flexibly, and design thus that medium is isolated from the outside fully, it is outer logical not have machinery, do not have the valve mechanism in the magnetomotive source of machinery wearing and tearing.

Embodiment
What the temperature heat-sensitive element of present embodiment adopted is the structure that the liquid thermometer bulb adds bellows.The total composition is seen accompanying drawing and explanation.Now in conjunction with the accompanying drawings embodiment is described.
On valve body (1) structure top enterprising, that go out down, the valve gap (7) of a band cover is arranged, in the inner chamber of valve gap (7), a self-powering type spool, valve rod are arranged, spool is by upper-lower seal circle (4), and piston column (5) is formed; Valve rod is made up of upper valve rod (8), lower valve rod (2), magnetic post (17), rubber sleeve (3); Upper valve rod (8) is in valve gap (7) inner chamber inserts sleeve pipe; The outside of valve gap (7) sleeve pipe is with a circle cover (15) that can move up and down outside sleeve pipe, be inlaid with a magnet ring (16) in the circle cover (15), and moving up and down of magnet ring (16) can drive valve rod by magnetic post (17) and also move up and down; The outside of circle cover (15) is with a reset spring (9), and drive link (14) is withstood on the top of circle cover (15), and the top that the temperature heat-sensitive element is the bellows (13) in the thermometer bulb (10) is withstood at drive link (14) top; Thermometer bulb (10) is installed on the interior gear frame (12) of regulating handle (11); Piston column (5) is arranged in the spool, there is a relief hole (6) inside of piston column (5), upper shed and valve gap (7) internal upper part spatial communication, and can be covered by the sealing cover (19) on the lower valve rod (2), the downside opening communicates with the water inlet of valve body, the top of piston column (5) is with seal ring (20), and last seal ring (20) is valve inleting water mouth and valve gap (7) internal upper part spatial separation, lower seal (4) but water outlet (21) on the shutoff valve body; Lower valve rod (2) passes piston column (5) inner chamber, and dynamically is connected with piston column (5) by a rubber sleeve (3).Owing to have relief hole (6) in the piston column (5), thus piston column (5) can be under the drive of valve rod moving up and down freely.Working principle is summarized as follows: when valve is in open mode, because valve gap (7) inner chamber equates that with water inlet, water outlet pressure valve rod and spool can move downward under external force.When the ambient temperature around the thermostat valve rises, the interior media expansion pressure of thermometer bulb (10) increases, force bellows (13) compression, promoting drive link (14) and circle cover (15) and magnet ring (16) moves downward, magnet ring (16) promotes the magnetic post (17) in the upper valve rod (8) again, thereby driving valve rod moves downward, sealing cover (19) on the lower valve rod (2) is immediately gone up relief hole (6) with piston column (5) and is stopped up, lower seal (4) with piston column (5) when moving down with water outlet (21) shutoff on the valve body (1), valve closing or turn down rate-of flow.Because flowing to the thermal medium of radiator reduces, ambient temperature slowly descends, when temperature drops to the setting value of thermostat valve, pressure in the thermometer bulb (10) descends, and bellows (13) recovers reset condition gradually, and the reset spring (9) outside circle cover (15) drives magnet ring (16) and rises, valve rod begins to promote, leave relief hole in a flash at sealing cover (19), intake pressure forces the valve gap chamber pressure consistent with discharge pressure through relief hole, and valve is opened rapidly.If there is not relief hole (6) on the piston column, after valve closing, because the valve gap inner chamber at this moment along with the lifting of valve rod, must cause the valve gap chamber pressure to increase, magnet ring is difficult to drive valve rod and rises, and causes valve not opened.Same valve if there is not relief hole, when valve rod moves down, will form negative pressure at the valve gap inner chamber under magnetic force in closing closed procedure, valve rod moves down difficulty, causes valve not close equally.Regulating handle (11) can drive gear frame (12) by screw thread, the pressurized degree of gear frame (12) can regulate reset spring (9), thus set extent of opening with the temperature corresponding valve.
