Description

Technical Field

[0001] The utility model belongs to the technical field of machinery and relates to an oil and air release valve, in particular to a quick release valve structure. Background Art

[0002] In many cases, gas turbines require oil discharge functions and air discharge functions to meet usage requirements, so it is necessary to design oil discharge devices and air discharge devices at the same time.

[0003] Commonly used oil drain devices mostly use metal plugs. When draining the oil, the fuse and plug are removed with corresponding tools to drain the oil. After draining the oil, the plug is installed and the fuse is engaged. Using this device can easily cause oil splashing.

[0004] Commonly used air release devices generally adopt a valve structure and also require special opening methods such as pressure.

[0005] Both oil and air release devices have their own unique structural forms and lack structural uniformity. Currently, there is a demand for a unified structure to achieve rapid oil and air release. This has the advantages of being easy to operate, maintain, and replace. Therefore, certain requirements are placed on this unified oil and air quick release structure, including good sealing performance, good pressure resistance, the ability to quickly open and release oil and air without sticking, and the ability to continuously release oil and air after opening without constant operation. Utility Model Content

[0006] In order to solve the above problems, the utility model provides a quick release valve structure, which can be used as an oil release device alone or as an air release device, and meets many requirements such as sealing and pressure resistance of a unified oil and air quick release structure.

[0007] The technical solutions of the present invention are as follows:

[0008] A quick-release valve structure comprises: a valve body and a valve core; the bottom of the valve body is an inlet, the side of the valve body is an outlet, the valve core is inserted into the valve body, a spring seat is installed at the valve body outlet, a spring is provided between the bottom of the valve core and the spring seat, the spring causes the upper annular surface of the valve core to contact the conical surface inside the valve body, thereby blocking the passage from the inlet to the outlet in the valve body; the valve core extends above the valve body, and a sealing structure is provided between the upper part of the valve core and the valve body.

[0009] Furthermore, it also includes a valve cap and a buckle. The upper part of the valve core extending out of the valve body is covered with the valve cap, and a pluggable buckle is provided between the valve cap and the valve body.

[0010] Furthermore, it also includes a valve cover, a valve cover is provided above the valve body, and the valve core passes through the valve cover; a second sealing ring is provided between the valve core and the valve cover; and a first sealing ring is provided between the valve cover and the valve body.

[0011] Furthermore, a transverse boss is provided in the middle section of the valve core, and a corresponding groove is provided on the valve cover corresponding to the position and shape of the boss; when the valve core is in the sealing position, the boss of the valve core is arranged in the groove of the valve cover.

[0012] Furthermore, a handle for rotation is provided on the valve cap.

[0013] Furthermore, a vulcanized rubber pad is provided on the upper ring surface of the valve core.

[0014] Technical effects of this utility model:

[0015] This utility model utilizes a plug combined with a valve to achieve oil or air release without splashing. A protrusion in the center of the valve core prevents the spring from returning during the process. Multiple sealing features ensure a secure seal. This device offers a novel structure, simple operation, and promising application prospects. BRIEF DESCRIPTION OF THE DRAWINGS
