Abstract
The utility model relates to a protector for a pressure gage, which is used for performing a buffering protection function during sudden pressure variation. The structure of the utility model is characterized in that an adjustment sheet (3) is arranged in an upper cover (1) and a base (4) and is pressed by a reset spring. The utility model makes an adjustment hole open and close by the moving of the adjustment sheet to realize the buffering protection function to the pressure gage.
Description
The manometric protective device that the utility model relates to monitoring pressure when sharply changing.
The utility model has unidirectional buffer action to monitoring pressure.
When tensimeter has fly back maybe the system of instantaneous negative pressure can occur at monitoring pressure, often because of indicator returns the zero too fast crooked and machinery part damage misalignment of pointer that causes, bring loss to commercial production, serious meeting causes danger.
For addressing this problem, normally with in manometer tube, making impact damper on the narrow meshed screw, but brought because of of the hysteresis of the little medium in hole by causing slowly, the value that the table indication rises to can't be made at any time exactly and it can not be used.
The purpose of this utility model provides a kind of one-way damper, and it can be effectively plays buffer action to the pressure of quick decline, can not form buffering to unlifting pressure, practicably protect manometric effect thereby reach.
The purpose of this utility model be achieved in that one by on in the middle of lid and bottom sit, adjustment sheet and the return spring that elastic force is very little--leaf spring or ring spring that a band damping hole and adjustment hole are arranged, packing ring of whole formation, with the packing ring using method, be contained in the pressure tapping, when pressure rises, pressure backs down adjustment sheet, pressure is passed to tensimeter fast by adjustment hole, thereby reach the hysteresis of elimination when boosting, adjustment sheet when pressure descends is because the effect of return spring, attached to taking at the end, only, reach pointer and slowly return zero effect by the damping hole step-down.
Hysteresis damping when the utility model rises because of unmatchful pressure, thereby the place that can be used for this is had higher requirements.
The concrete structure of utility model is provided by following examples and accompanying drawing thereof, and return spring adopts leaf spring.
Have as accompanying drawing 1, its structure: 1. loam cake; 2. leaf spring; 3. adjustment sheet; 4. the end, sat
By on the space height of lid and bottom in sitting be preferably 1/3 of internal diameter, on the adjustment sheet aperture of aperture and adjustment hole than generally use 1:10, regulates hole count be 3 better, return spring is employing scale copper formation during for leaf spring.
Claims (3)
1, the sudden change protection pressure meter device of a kind of unidirectional compensator or trimmer pressure; it is characterized in that 3. this device has an adjustment sheet by moving the switch adjustment hole; one return spring is arranged on it, and adjustment sheet and return spring are contained in the cavity that 4. 4. is made of with loam cake base.
2, according to the described device of claim, it is characterized in that 3. by mobile adjustment sheet
The switch adjustment hole reaches the effect of unidirectional compensator or trimmer pressure.
3, according to claim 1,2 described devices, it is characterized in that integral body with a cavity body structure, the similar packing ring of external form, total is installed in the pressure tapping with the packing ring form.
