Novel self-closing liquidometer

Abstract

The invention discloses a novel self-closing liquidometer comprising a liquidometer housing, an upper liquid level measuring assembly, and a lower liquid level measuring assembly; the liquid level measuring assembly comprises a push rod, a sleeve, a hollow bolt and a valve bush; the push rod penetrates the sleeve, the hollow bolt, the liquidometer housing, a mount hole and a valve bush end, inserts into a valve core groove, and is coupled via threads; the valve core, a spring, a stand ring and a stop ring are arranged in the valve bush; one end of the spring pushes against the valve core, andthe other end abuts on the stand ring; the stop ring is arranged by the stand ring, and is clamped in the inner wall of the valve bush; the push rod pushes inward, the valve core opens, and the liquidin a fuel tank flows into the liquidometer housing via a looped gap between the valve bush and the valve core; when the push rod loosens, the valve core and the valve bush can form a conical sealingunder the reset force of the spring. The dual-self closing functions are added on the basis of an YWZ type liquidometer; a non-self closing liquidometer can be replaced by the self closing liquidometer without making any changes of an original fuel tank; the novel self-closing liquidometer is high in universalization, and wide in application scopes.

Description

technical field [0001] The invention specifically relates to a new self-closing liquid level gauge, which is usually installed on the wall of an oil tank or other liquid container, and is used to observe the liquid level change in the container. Background technique [0002] A liquid level gauge is a commonly used instrument installed on the wall of a liquid container to observe changes in the liquid level of the liquid in the container. Most of the oil tanks, lubricating devices, and cooling boxes currently used on mechanical equipment are (GB1161-90) YWZ type plexiglass liquid level gauges. This type of liquid level gauge is ideal for equipment installed indoors or in fixed positions. There is no problem, but for equipment such as deck machinery and construction machinery that need to be installed outdoors and the liquid level gauge often moves with the host, a problem that is often encountered is that the shell of the liquid level gauge is easy to install because it is ma...

Problems solved by technology

[0007] 4. When observing the liquid level of the ULG type liquid level gauge, first press the handwheel of the self-closing valve at the same time, open the self-closing valve to let the liquid in the container flow into the liquid level gauge, and press the handwheel at the same time to use a lot of force. Operation is not very convenient
