Summary of the invention
the object of the present invention is to provide a kind of cutting type tensimeter short circuit preventing tensimeter from damaging.
technical scheme of the present invention is: cutting type tensimeter short circuit, comprise the first housing, one end of described first housing has short circuit import, the other end of the first housing has short circuit outlet, the side of the first housing is connected with the second housing, first housing and the second housing pass through open communication, slide block is provided with in opening, the first cavity for holding slide block is provided with in second housing, limiting plate is provided with in first cavity, the first spring is connected with between limiting plate and the first cavity inner wall, be provided with for hindering slide block to the stop means of movement in the second housing between limiting plate and slide block, the second spring is connected with on first cavity inner wall and between slide block, the second cavity is provided with above first cavity, pin is provided with in second cavity, the 3rd spring is connected with between pin and the second cavity inner wall, pin and limiting plate offset.
beneficial effect of the present invention is: short circuit import is connected with the valve be connected on measured medium pipeline, short circuit outlet is connected with tensimeter, and open valve, measured medium enters in the first housing, and enter in tensimeter through the first housing, the pressure of tensimeter display measured medium; And measured medium also can enter into opening, measured medium contacts with slide block, promotion slide block moves by measured medium in the second housing, be provided with for hindering slide block to the stop means of movement in the second housing between limiting plate and slide block, therefore obstruction slide block moves by stop means, and slide block stops after moving a segment distance.
when the pressure durations of measured medium increases, slide block will move always in the second housing, pressure increase is to during close to manometric maximum range, slide block will depart from opening, slide block is by the elastic force due to self gravitation and the second spring, enter in the first cavity, now slide block contacts with limiting plate, press limiting plate to move downward, limiting plate departs from the position offseted with pin, pin is by unfettered, and pass through the elastic force of the 3rd spring, move to opening direction, enter in the first housing through opening, and short circuit import is closed, measured medium is made to be dammed in short circuit import, thus make the pressure of measured medium not transmitting in tensimeter, index in tensimeter fixes close to maximum range place, thus prevent tensimeter to damage.
further: the side away from pin in opening is provided with limited block.Can ensure that slide block can not enter in the first housing, slide block is limited in opening.
further: stop means comprises block, be connected with the 4th spring between block and limiting plate, opposite side and the slide block of block offset.Measured medium contact slipper, obstruction slide block, due to the elastic force of the 4th spring, moves by block in the second housing.
further: the first cavity inner wall basal sliding connects push rod, push rod extends to the second outside through the first cavity wall, the other end of pin is fixedly connected with pull bar, and pull bar extends to the second outside through the second cavity wall, and pull bar and the second housing are slidably connected.When pressure is reduced to below tensimeter maximum range, pull pull bar, pin is resetted, then promotes push rod slide block is resetted.
Accompanying drawing explanation
fig. 1 is the schematic diagram of cutting type tensimeter short circuit embodiment of the present invention.
Embodiment
below by embodiment, the present invention is further detailed explanation:
reference numeral in Figure of description comprises: the outlet of short circuit import 1, first housing 2, short circuit the 3, second housing 4, limited block 5, slide block 6, block 7, the 4th spring 8, pin 9, the 3rd spring 10, pull bar 11, limiting plate 12, second spring 13, push rod 14, first spring 15.
embodiment is substantially as shown in Figure 1: cutting type tensimeter short circuit, comprise the first housing 2, one end of described first housing 2 has short circuit import 1, the other end of the first housing 2 has short circuit outlet 3, the side of the first housing 2 is connected with the second housing 4, first housing 2 and the second housing 4 pass through open communication, slide block 6 is provided with in opening, the left side of opening inner slide 6 is provided with limited block 5, the first cavity for holding slide block 6 is provided with in second housing 4, limiting plate 12 is provided with in first cavity, the first spring 15 is connected with between limiting plate 12 and the first cavity inner wall, be provided with for hindering slide block 6 to the stop means of movement in the second housing 4 between limiting plate 12 and slide block 6, stop means comprises block 7, the 4th spring 8 is connected with between block 7 and limiting plate 12, opposite side and the slide block 6 of block 7 offset, the second spring 13 is connected with on first cavity inner wall and between slide block 6, the second cavity is provided with above first cavity, pin 9 is provided with in second cavity, the 3rd spring 10 is connected with between pin 9 and the second cavity inner wall, pin 9 and limiting plate 12 offset, first cavity inner wall basal sliding connects push rod 14, it is outside that push rod 14 extends to the second housing 4 through the first cavity wall, the other end of pin 9 is fixedly connected with pull bar 11, it is outside that pull bar 11 bar extends to the second housing 4 through the second cavity wall, pull bar 11 and the second housing 4 are slidably connected.
