Description
Technical field
The utility model relate to a kind of manometric component, has been specifically related to a kind of tensimeter protection short circuit.
Background technology
Tensimeter short circuit refers to that the connection between tensimeter and measured medium pipeline compensates, in order to be connected the inner linker with pipe interior of tensimeter.
The Chinese patent patent No. is CN204214591U, discloses a kind of tensimeter protection short circuit, the internal thread that upper end is provided with tensimeter gauge outfit is connected of the housing of tensimeter protection short circuit, and the lower end of housing is provided with the outside screw being connected with pipeline valve; The cavity of housing is built-in with piston, and piston side wall has two annular recessess being parallel to each other, and is all fixed with sealing rubber ring in two annular recessess; The screw internal fixtion of housing upper end has gasket seal. This kind of tensimeter, if the pressure durations of measured medium becomes big, piston can upwards be walked always, tensimeter inside can be applied pressure by deicing fluid force feed, and pointer is moved towards maximum range with continuing, until hand motion is to maximum range place, when pressure is excessive, pointer exceedes maximum range or loses, and finally causes tensimeter to damage.
Practical novel content
The purpose of this utility model is to provide the medium in a kind of automatic cut-out pipeline, prevents pressure from crossing the tensimeter that roughly tensimeter damages and protects short circuit.
The technical solution of the utility model is: comprise nipple, the two ends of nipple are respectively equipped with short circuit import and short circuit outlet, nipple is provided with pressure channel at short circuit entrance end, nipple sidewall is provided with housing, pressure channel communicates with housing, be provided with in housing erect to the first spring and the push rod that is connected with the first spring; Nipple also has between short circuit outlet and pressure channel and is connected hole, horizontal pin also it is provided with in housing, being provided with the 2nd spring between pin and housing, the handheld terminal of pin is through the 2nd spring and housing and extends to outside housing, and the free end of pin is positioned at and connects hole; Being connected with card bar on pin, card bar is connected by the 3rd spring with housing, and the motion track of push rod is through card bar.
In technique scheme: short circuit import is connected with the valve being connected on measured medium pipeline, short circuit outlet is connected with tensimeter, opens valve, and measured medium enters in nipple, and enter in tensimeter through nipple, the pressure of tensimeter display measured medium;And measured medium also can enter into housing by pressure channel, measured medium contacts with push rod bottom, and the first spring is stretched, and promotion push rod is moved up by measured medium.
When the pressure durations of measured medium increases, push rod will move up always; Pressure increase is to during close to manometric maximum range, push rod can to card bar reactive force upwards pushed up, now card bar can depart from by power and pin, pin is by unfettered, and by the elastic force of the 3rd spring, to the motion of connection direction, hole, enter in nipple through connecting aperture, and nipple is closed, measured medium is made to be dammed in nipple, thus the pressure making measured medium not transmitting in tensimeter, the index in tensimeter fixes close to maximum range place, thus prevents tensimeter from damaging.
When, after Recovery and rebuild, push rod can compress the first spring under gravity, push rod recovers original position, and card bar also can recover original position under the elastic force of the 3rd spring, pulls pin simultaneously, and compression the 2nd spring, pin is retracted into original position place and connects with card bar card.
Further: pin be connected between hole to be provided with gasket, prevent medium in nipple during proper flow, medium is to housing seepage.
Further: being provided with sealing-ring between push rod and housing, sealing-ring seals.
Further: the free end of pin is provided with draw ring, conveniently pull pin to reset.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of the utility model tensimeter protection short circuit embodiment.
Embodiment
Below by embodiment, the utility model is described in further detail:
Reference numeral in Figure of description comprises: nipple 1, short circuit import 2, short circuit outlet 3, pressure channel 4, housing 5, first spring 6, push rod 7, pin 8, the 2nd spring 9, card bar 10, the 3rd spring 11.
Embodiment is substantially as shown in Figure 1: tensimeter protection short circuit, comprise erect to nipple 1, the two ends of nipple 1 are respectively short circuit import 2 and short circuit outlet 3, nipple 1 has pressure channel 4 at short circuit import 2 end, being provided with housing 5 on nipple 1 sidewall, pressure channel 4 communicates with housing 5, be provided with in housing 5 erect to the first spring 6, first spring 6 is connected with push rod 7, is provided with sealing-ring between push rod 7 and housing 5. nipple 1 exports at short circuit also to have between 3 and pressure channel 4 and is connected hole, horizontal pin 8 also it is provided with in housing 5, the 2nd horizontal spring 9 is installed between pin 8 and housing 5, pin 8 is through the 2nd spring 9 and housing 5, the draw ring of pull bar extends to outside housing 5, the free end of pin 8 is positioned at and connects hole, pin 8 be connected between hole to be provided with gasket, thus connection hole is blocked, pin 8 has groove, card bar 10 also has groove, pin 8 and card bar 10 are connected together by groove, card bar 10 and housing 5 by erect to the 3rd spring 11 be connected, push rod 7 when moving up, card bar 10 upwards can be pushed up, itself and pin 8 are departed from.
During use, short circuit import 2 is connected with the valve being connected on measured medium pipeline, and short circuit outlet 3 is connected with tensimeter, opens valve, and measured medium enters in nipple 1, and enters in tensimeter through nipple 1, the pressure of tensimeter display measured medium; And measured medium also can enter into housing 5 by pressure channel 4, measured medium contacts with push rod 7 bottom, and the first spring 6 is stretched, and promotion push rod 7 is moved up by measured medium.
When the pressure durations of measured medium increases, push rod 7 will move up always; Pressure increase is to during close to manometric maximum range, push rod 7 can to card bar 10 1 reactive forces upwards pushed up, now card bar 10 can depart from by power and pin 8, pin 8 is by unfettered, and by the elastic force of the 3rd spring 11, to the motion of connection direction, hole, enter in nipple 1 through connecting aperture, and nipple 1 is closed, measured medium is made to be dammed in nipple 1, thus the pressure making measured medium not transmitting in tensimeter, the index in tensimeter fixes close to maximum range place, thus prevents tensimeter from damaging.
When, after Recovery and rebuild, push rod 7 can compress the first spring 6 under gravity, and push rod 7 recovers original position, card bar 10 also can recover original position under the elastic force of the 3rd spring 11, pulling draw ring, pin 8 compresses the 2nd spring 9 simultaneously, and pin 8 is retracted into original position place and connects with card bar 10 card.
