Abstract

The invention provides a buoy type level gauge adjustment method and a device. The device is characterized in that a bracket with a gripping head is fixedly mounted on a blind flange at the upper end of a buoy chamber; a slide bar capable of moving vertically is perpendicularly arranged on a cross beam of the bracket; a spring scale is hung at the lower end of the slide bar; and a hook is hung at the lower end of the spring scale. The method comprises the following steps: hooking the hook onto the upper end of a floater suspender; according to the prepared liquid level buoyancy value, adjusting the slide bar to lead the spring scale to move; and adjusting the level gauge after comparing the buoyancy value displayed by the spring scale with the data displayed by the level gauge. The invention has the advantages of simple and convenient adjusting operation, convenient counting and observation, and convenient, accurate and timesaving field use.

Description

Float level meter adjusting process and device

Technical field

What the present invention relates to is float level meter adjusting process and device, is to the float level meter correction before use and the method and the device of check.

Background technology

Prior art float level meter adjusting process has two kinds:

A kind of is that water is followed, float level meter is installed on the tank body, the flange valve that dock with tank body the float chamber is closed, even the float chamber cuts off with jar chamber, connect a transparent hose in the bottom, float chamber, and the other end that makes this transparent hose places the position that is higher than the float chamber, open float level meter float chamber upper flanges and cover the bleed screw hole of offering, by this hole water is injected float chamber, and demonstrate the water level of the setting identical with float chamber by transparent hose, then with the adjustment of comparing of liquid level gauge transmitting and displaying data.Verification need be carried out each liquid level point, so water filling and discharge water and want repeated multiple times to carry out just finishing adjustment work, its shortcoming need manually be carried out with enough water, and water filling repeatedly, inconvenient operation discharges water, when being that liquid level gauge is installed on the tall can or on the high-order pylon time, calibration personnel will bear the operation of climbing to a higher point of bucket and water pipe, and are very inconvenient, particularly just more inconvenient during winter.In addition, the density of liquid that detects when liquid level gauge is during greater than water, and the full scale buoyancy of the full scale buoyancy of floating drum during greater than the water school just can not carry out the check of full scale in this case.

Another kind is to hang heavy method, it is indoor check addition, at first float level meter is horizontally fixed on the isolated plant, again purpose-made pallet is hung on the lever of float level meter, after having calculated the buoyancy value, add and subtract weights again on pallet, the buoyancy of corresponding each liquid level is then with the adjustment of comparing of liquid level gauge transmitting and displaying data.This method can only be carried out indoor, and it is accurate to the float level meter horizontal fixed to require, and this is also feasible concerning liquid level gauge manufacturer, but not convenient and practical concerning the user.In addition, when putting and taking down the weights of various Different Weight repeatedly, also make a mistake easily, cause verification to make a mistake easily.

Summary of the invention

The objective of the invention is to improve, a kind of simple to operation, accurately float level meter adjusting process and device efficiently are provided at the not shortcoming deficiency of above-mentioned prior art.

Float level meter adjusting process of the present invention, use the support of a Tourniquet clamping head, support is fixedly mounted on the blind flange of upper end, float level meter float chamber by chuck, be provided with a crossbeam in the upper end of support, but on crossbeam, vertically be provided with the slide bar that up-down adjustment moves, the lower end of slide bar is hung and is connected tensile force type weighing batcher---spring balance, the spring balance lower end is hung and is connected a suspension hook, open the bleed screw that float level meter float chamber upper flanges covers, the suspension hook lower end is stretched into by the bleed screw hole, suspension hook is hooked in the upper end of float suspension rod, regulate the slide bar that the adjusting descended on the rack beam is moved by calculating good liquid level buoyancy value, the pulling spring balance shows the adjustment of comparing of buoyancy value and liquid level gauge transmitting and displaying data with spring balance.

Float level meter adjusting process of the present invention, operative installations is simple, adjustment convenience easy and simple to handle, counting intuitive and convenient, overcome present technology and used weights to make a mistake easily and the difficult shortcoming of water school method, particularly used very convenient, accurately quick at the scene.

Description of drawings

Accompanying drawing is a float level meter calibration apparatus example structure synoptic diagram of the present invention.

Embodiment

Shown in accompanying drawing embodiment, float level meter calibration apparatus of the present invention includes support 1, be provided with the clamping mechanism for installing that chuck 11 and trip bolt 12 constitute in the lower end of support 1, be provided with crossbeam 13 in the upper end of support, on crossbeam 13, vertically be provided with threaded rod slide bar 14 moving up and down, on threaded rod slide bar 14, be provided with setting nut 15, cooperate with pin 16 on the crossbeam 13 and prevent that slide bar 14 from rotating offering chute on the threaded rod slide bar 14, claim 17 at 14 times hanger springs of slide bar, hang suspension hook 18 17 times at spring balance.

The present invention is during to the float level meter adjustment, the float chamber 20 of float level meter is cut off with jar chamber, be fixed on support 1 on the blind flange 21 of 20 upper ends, float level meter float chamber by chuck 11 and trip bolt 12, open the bleed screw 22 on the float level meter float chamber upper flanges lid 21, suspension hook 18 lower ends are stretched into by the bleed screw hole, suspension hook 18 is hooked in the upper end of float suspension rod 23, by rotation setting nut 15 threaded rod slide bar 14 is moved up and down by calculating good buoyancy value, pulling spring balance 17 is with the adjustment of comparing of spring balance 17 demonstration buoyancy values and liquid level gauge transmitting and displaying data.
