Abstract
The utility model discloses a pressure-spring type instrument module, which comprises a pipe junction and a pressure spring. The upper end of the pipe junction is riveted with a junction rack; two ends of an air drain are respectively communicated and welded with the upper end of the pipe junction and one end of the pressure spring to a whole. An L-shaped upper rack and a lower rack are connected to form the junction rack; a small hole used for fixing a needle axis and a dial is positioned on the upper rack. The pressure-spring type instrument module is applied to the pressure-spring type instrument on a tractor and a combustion engine; compared with the prior art, 60 percent of copper product can be saved, thereby greatly reducing the instrument production cost and simplifying the processing technology; the welding is convenient, and the condition of weeping and blocking is reduced, thus the reliability of the product is strengthened and the quality of the product is improved.
Description
Technical field:
The utility model relates to a kind of meter movement, particularly is applied to employed movement in the spring-tube type instrument on tractor, the internal combustion engine.
Background technology:
The spring-tube type instrument is to utilize the distortion of bourdon tube to come the instrument of gaging pressure and temperature variation.Original spring-tube type meter movement mainly is made of pipe adapter and bourdon tube.The mouth of pipe one end of bourdon tube directly is welded on the pipe adapter, and the other end blocks with sealing plug.The shortcoming of this structure is: 1, the pipe adapter volume is big, consumes a large amount of copper materials; 2, be difficult for welding, leakage easily, inner chamber easily stops up.
Summary of the invention:
The purpose of this utility model provides a kind of spring-tube type meter movement, can reduce cost of products, improves the instrument function index.
The purpose of this utility model realizes as follows: this spring-tube type meter movement, relate to pipe adapter and bourdon tube, pipe adapter upper end riveted joint support, there are snorkel two ends to be communicated with integrally welded with pipe adapter upper end and bourdon tube one end respectively, the axially extending bore of pipe adapter inside center is communicated with bourdon tube by snorkel like this, and bourdon tube is fixed by snorkel and pipe adapter, saved the copper seal chamber that original meter movement pipe adapter top is connected with bourdon tube, can save material, also simplify technology, be convenient to welding.
Adapter bracket is connected and composed by the lower carriage and the upper bracket of L type, leaves the aperture that is used for fixing needle shaft and dial plate on the upper bracket.Adapter bracket is used for fixing needle shaft and dial plate etc.
The utility model is compared with original product, can save 60% copper material, greatly reduces the instrument cost, has simplified processing technology, is convenient to welding, and the situation that reduces leakage and obstruction occurs, thereby has strengthened reliability of products, has improved the quality of product.
Description of drawings:
Accompanying drawing is the structural representation of the utility model spring-tube type meter movement.
Embodiment:
With reference to accompanying drawing, this spring-tube type meter movement mainly is made of pipe adapter 1 and bourdon tube 5, and bourdon tube 5 is pressed into flat copper band and embowment by brass or bronze pipe, and the one end is dead with sealing plug 6 welderings, and the other end and snorkel 3 weld together; Pipe adapter 1 is made by brass, and periphery has screw thread, and there is the plane of a square boss upper end, and inside center has axially extending bore, and pipe adapter 1 upper end is by its boss riveted joint support; Adapter bracket is connected and composed by screw by the lower carriage 2 of L type and upper bracket 4, is made by cold drawing, and upper bracket 4 leaves 3 apertures, is used for fixing needle shaft and dial plate, and the other end of snorkel 3 is communicated with integrally welded with pipe adapter 1 upper end.
Claims (2)
1, a kind of spring-tube type meter movement relates to pipe adapter and bourdon tube, it is characterized in that: pipe adapter (1) upper end riveted joint support has a snorkel (3) two ends to be communicated with integrally welded with pipe adapter (1) upper end and bourdon tube (5) one ends respectively.
2, spring-tube type meter movement according to claim 1 is characterized in that: adapter bracket is connected and composed by the lower carriage (2) and the upper bracket (4) of L type, and upper bracket leaves the aperture that is used for fixing needle shaft and dial plate on (4).
