Description

Technical Field

[0001] The utility model belongs to the technical field related to fuel tank components, in particular to a float valve comprehensive test bench. Background Art

[0002] The float valve is a common mechanical device widely used in various industrial equipment and mechanical systems. Its main function is to control the flow of fluids through the buoyancy of the float. It is usually used in liquid transportation, storage and discharge systems. In the corresponding oil tank, in order to work well, it is equipped with an external float valve for easier installation and maintenance. The technical status of the float valve needs to be tested on a test bench, but it still has the following disadvantages in actual use:

[0003] During the operation of the float valve comprehensive test bench, it is installed directly through the installation structure. During the installation process, the pipeline of the float valve is directly placed on the test bench. When the air pressure in the test bench changes, the float valve will swing, affecting the safety of the work;

[0004] During the operation of the float valve comprehensive test bench, air is directly blown in or extracted. However, under actual working conditions, the air pressure in the oil tank usually changes rapidly. In the face of different test conditions, the applicability of the test is not high enough.

When working, oil for testing is contained in a centralized manner through the fixing box and provided to the working position of the float valve to be tested, the float valve to be tested is contained therein through the containing box, a threaded rod is threadedly connected thereto through the fixing seat, and air is supplied to the fixing box through the air supply box to simulate the operation of the float valve under positive and negative pressure conditions in the fixing box.

[0008] Furthermore, a through-tube is fixed through the fixed box at one end of the housing box, a connector is fixed at the top of the through-tube, and a pressure gauge is fixed through the top of the housing box at a position symmetrical to the through-tube. When the housing box is working, it is connected to the connector through the through-tube.

[0009] Furthermore, a transparent ruler is fixed through one side of the fixed box, a threaded rod is threadedly connected to the upper inner portion of the fixed seat, an end of the threaded rod close to the side fixed plate is rotatably connected to an arc-shaped leaf spring, and an end of the threaded rod away from the arc-shaped leaf spring is fixed to a rotating frame. When the fixed box is working, the oil content in the fixed box is determined by the transparent ruler.

[0010] Furthermore, a fixed pipe is fixedly connected to the upper part of one end of the fixed box close to the air transmission box, a connecting nozzle is fixedly connected to the end of the fixed tube away from the fixed box, and a switch valve is fixed to the middle part of the circumference of the fixed tube.

[0013] The utility model has the following beneficial effects:

[0014] The utility model solves the problem that the float valve is easy to swing during the operation of the float valve comprehensive test bench by arranging a fixing box, a receiving box and a fixing seat. If the connecting hose on the external float valve is long, the hose is arranged in the flexible pressure groove, and then the threaded rod is rotated. Through the rotation of the threaded rod, the arc-shaped leaf spring is driven to move toward the flexible pressure groove until the arc-shaped leaf spring moves to clamp the connecting pipe of the float valve, and the float valve is placed in the receiving box for testing. The damage of the float valve caused by swinging during the test is reduced, and the integrity of the float valve test is increased.

[0015] The utility model solves the problem of insufficient applicability of the float valve comprehensive test bench test by arranging a fixed box and an air supply box. When performing a negative pressure test, the air in the air supply box is extracted through the air nozzle. When performing a positive pressure test, the air is input into the air supply box through the air nozzle. After the electric control valve is opened, the positive pressure or negative pressure test is performed on the fixed box. BRIEF DESCRIPTION OF THE DRAWINGS

A side fixing plate 201 is fixed to the side of the receiving box 2 away from the fixing seat 3. The fixed plate 201 fixes the flexible pressure groove 202 thereon and is arranged above the accommodating box 2. A flexible pressure groove 202 is fixed on one side of the side fixed plate 201 close to the inner center of the accommodating box 2. The flexible pressure groove 202 is used to accommodate and restrict the float valve pipe fitting that needs to be tested. An air delivery box 4 is fixed to the lower part of one end of the fixed box 1. The air for the impact airflow test is accommodated in the air delivery box 4. A pressure gauge 2 403 is fixed on the top of the air delivery box 4. The air pressure in the air delivery box 4 is measured by the pressure gauge 2 403.
