Abstract

The utility model relates to a reflecting metering scale. Connection parts are kept at both ends of a long edge made of aluminum alloy. A rectangular square tube with a removed middle part is made into a scale box (2), and the inner surface of the other long edge of the scale box (2) has dimension scale scales (5) made of front side reflecting materials. An upper cover (1) is arranged at the upper end of the scale box (2), and a righting block (7) is arranged at the lower end of the scale box. A floating ball (9) is connected with a scale rod (4) through a dimension scale seat (8), and a slide scale needle (3) arranged at the upper end of the scale rod (4) is fixed by a screw (10). Because the dimension scale scales (5) are made of the front side reflecting materials, the reflecting metering scale has the advantages of convenient observation, improved operating conditions for workers and high accuracy.

Description

Reflecting metering scale

The utility model relate to a kind of be applicable to industries such as oil, chemical industry need on the container of measuring liquid level, collection liquid storage amount can be reflective the metering scale.

The method of measuring liquid level on the sump oil retracting device of using always on the oil field, it is the pin type Liquid level scale, the pin type Liquid level scale is to make with the garden steel polishing of φ 6-φ 10mm, when observing liquid level, is to insert to release from tank deck to check that pot liquid is in position that scale floods.This method is outmoded, uses trouble, and accuracy is low, is difficult to when especially measure liquid level night see clearly, and is very inconvenient, and workman's operating conditions is very poor.

The purpose of this utility model provides a kind of manually-operated that do not need, and is convenient to observe the reflective metering scale of liquid level that can be reflective.

The utility model is achieved in that a kind of reflective metering scale, it is characterized in that having the both ends, a long limit of adopting the aluminium alloy manufacturing to leave the coupling part, the chi box (2) that the rectangle square tube that center section removes is made, inside surface on another long limit of chi box (2) indicates footage number scale (5) with the front reflectorized material, there is loam cake (1) chi box (2) upper end, the lower end has a center that the centralizer of slide opening (7) is arranged, there is the position of coupling part that a bearing (6) is installed in chi box (2) lower long edges, the ball float made from stainless steel (9), be connected with chi bar (4) by footage number seat (8), chi bar (4) penetrates chi box (2) by wiper block (7) slide opening, fixes the slide sign pin made from organic glass (3) with jackscrew (10) in chi bar (4) upper end.Footage number scale (5) can also be divided into high, medium and low three liquid level districts with different colours.

The advantage that the utility model compared with prior art has is:

1, owing to adopt the front reflectorized material to make footage number scale (5), is convenient to observe, especially has night the light source can be clearer, improved condition of work.

2, footage number pin (3) moves up and down along with level change, accuracy of measuring height.

The drawing of accompanying drawing is described as follows:

Fig. 1: the structural representation of reflective metering scale;

Fig. 2: the vertical view of reflective metering scale.

The utility model is described in further detail below in conjunction with accompanying drawing:

Accompanying drawing 1, accompanying drawing 2 have provided the basic structure of reflective metering scale.Chi box (2) adopts aluminium alloy square type square tube to make, the coupling part of certain-length is left at both ends on a long limit, center section removes, indicate the footage number scale (5) that adopts the front reflectorized material to manufacture at another long limit inside surface, be convenient to the workman and observe, also can adopt different colours to be divided into high, medium and low three liquid level districts on the scale surface.In chi box (2) upper end a loam cake (1) is installed, the wiper block (7) that there is slide opening at a center is installed in the lower end, there is the position of connection that a bearing (6) is installed in chi box (2) bottom, the ball float of making of stainless steel (9) is connected with chi bar (4) by footage number seat (8), chi bar (4) inserts chi box (2) by the slide opening of wiper block (7), load onto slide sign pin (3) on chi bar (4) top, fixing with screw (10).In use, it is installed in the tank deck appropriate location, tank level is changing at any time, and ball float (9) also moves up and down at any time, by slide sign pin (3) indicating positions, just can calculate the pot liquid storage.

If supporting with microcomputer, microcomputer just can write down at any time, calculate, prints the pot liquid storage, and turn on pump discharge opeing during high liquid level, pump trip during low liquid level.

Claims

1, a kind of oil that is used for, chemical industry needs measuring liquid level, reflective metering scale on the container of collection liquid storage amount, it is characterized in that adopting the two ends, a long limit of aluminium alloy manufacturing to leave the coupling part, the rectangle square tube chi box (2) that center section removes, another long limit inside surface at chi box (2) adopts the front reflectorized material to indicate footage number scale (5), a loam cake (1) is stamped in chi box (2) upper end, the lower end has a center that the wiper block of slide opening (7) is arranged, chi box (2) lower long edges leaves the position of coupling part and adorns a bearing (6), make ball float (9) with stainless steel, be connected with chi bar (4) by footage number seat (8), chi bar (4) inserts chi box (2) by wiper block (7) slide opening, and a slide sign pin (3) made from organic glass is fixed with jackscrew (10) in the end thereon.

2, reflective according to claim 1 metering scale is characterized in that the available different colours of footage number scale (5) is divided into high, medium and low three liquid level districts.
