Abstract
The utility model relates to a novel connection structure for a pressure gauge joint and a bottom shell. The joint is arranged on the bottom shell and is fixed on the bottom shell through three points; and an elastic seal ring is arranged between the joint and the bottom shell. In the connection structure, a three-point fixation mode is adopted, so that the connection between the joint and the bottom shell is more reliable, and the joint and the bottom shell do not easily become loose even in an environment with violet vibration; meanwhile, the elastic seal ring is arranged between the bottom shell and the joint; and due to the structural improvement, the connection structure has the advantages of reliable connection, high sealing property and the like, and the pressure gauge is in a superior working state for a long time.
Description
Technical field
The utility model relates to the syndeton of a kind of pressure tapping and drain pan, belongs to the observation and control technology field.
Background technology
Pressure tapping is the vitals in the tensimeter, fix by two screws between existing pressure tapping itself and the drain pan, have following defective: 1) fixed form of two screws make fix between the two unreliable, especially in vibrating stronger environment, vibration between the two makes and is easy to generate the gap between the two, causes leakage of oil between the two; 2) after the long-term vibration, connection between the two is loosening, or build-up of pressure represent to be worth inaccurate, influence manometric measuring accuracy, this seems inapplicable for the occasion that requires the comparison high measurement accuracy.
The utility model content
The utility model is at above-mentioned defective, and purpose is to provide a kind of syndeton that connects reliable pressure tapping and drain pan.
The technical solution of the utility model is: the utility model joint is fixed on the drain pan by 3, establishes elastic seal ring between joint and the drain pan.
Described joint is by three dismountable being connected on the drain pan of screw.
Described O-ring seal is for circumferentially being arranged on the O RunddichtringO between joint and the drain pan.
The utility model has the advantages that: the utility model passes through 3 fixed form, makes the connection between joint and the drain pan more reliable, even also be difficult for taking place loosening in vibrating stronger environment between the two; The utility model is provided with elastic seal ring between drain pan and joint simultaneously, by the improvement of above structure, the utlity model has advantages such as connection is reliable, good seal performance, can make tensimeter be in excellent duty for a long time.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the side view of Fig. 1.
1 is that joint, 2 is that O RunddichtringO, 3 is that drain pan, 4 is that screw one, 5 is that screw two, 6 is screw three among the figure.
Embodiment
The utility model joint 1 is connected on the drain pan 3 by screw 1, screw 25, screw 36, circumferentially establishes O RunddichtringO 2 between joint 1 and the drain pan 3.
The utility model can be between joint 1 and drain pan 3 circumferential uniform some O RunddichtringOs 2.
Claims (3)
1. the syndeton of pressure tapping and drain pan is characterized in that, joint is fixed on the drain pan by 3, establishes elastic seal ring between joint and the drain pan.
2. the syndeton of pressure tapping according to claim 1 and drain pan is characterized in that, joint is by three dismountable being connected on the drain pan of screw.
3. the syndeton of pressure tapping according to claim 1 and drain pan is characterized in that, described O-ring seal is for circumferentially being arranged on the O RunddichtringO between joint and the drain pan.
