Description

Small-sized electric boiler drainage device

Technical Field

The utility model relates to the technical field of water heater devices and equipment carried by aviation aircrafts, in particular to a small electric boiler drainage device.

Background

When the existing large-scale electric boiler equipment carried on the aircraft is maintained and replaced for storing water, the conventional design and manufacturing operation modes are adopted in the discharge mode, so that the efficiency is low, the installation is complicated, the multi-shaft equipment is required to be processed, the manufacturing cost is high, and the manpower and resource waste is caused. For this purpose, we propose a small electric boiler drain.

Disclosure of Invention

The utility model aims at solving the problems in the background technology and provides a small-sized electric boiler drainage device.

The technical scheme of the utility model is as follows: the utility model provides a small-size electric boiler drainage device, includes high accuracy liquid pipe, high accuracy liquid pipe outer lane cover is equipped with the guiding valve, the wash port has been seted up on the high accuracy liquid pipe, the inside groove has been seted up to the guiding valve inner circle, the assembly groove has been seted up respectively to inside groove inner wall both sides, be provided with flexible sealing ring in the assembly groove.

Preferably, the drain hole is positioned in the slide valve when the slide valve is in a closed state, and the drain hole is positioned on one side of the slide valve when the slide valve is in an open state.

Preferably, one side of the flexible sealing ring is mutually attached to the outer ring of the high-precision liquid conduit.

Preferably, the flexible sealing ring is mounted corresponding to the mounting groove.

Compared with the prior art, the utility model has the following beneficial technical effects: the utility model is communicated with the water drain valve of the small boiler, so that the slide valve is pushed along the outer edge of the high-precision liquid conduit, water stored in the heating system is discharged through the drain hole, the slide valve reversely moves to seal the drain hole, the water supply system normally supplies water, the pressure of the water supply system is communicated with each other due to the slide valve, the inner groove and the assembly groove, the pressure born by the flexible sealing rings at the two sides of the slide valve is equal, and meanwhile, the axial resistance is generated, so that the slide valve cannot leak due to the conditions of dead weight, equipment overturning and the like;

according to the utility model, the sliding is adopted to realize the sealing processing of the drainage relative to the screwed end face, the sliding valve is adopted to realize the visual operation relative to the rotational movement positioning blurring in the threaded hole, the leakage is invisible and optimized, meanwhile, the operation is simpler, the processing is easier to obtain, the maintenance is simple and efficient, the fault is visualized, the manufacturing and maintenance cost is reduced, and the assembly labor intensity is low.

Detailed Description

The technical scheme of the utility model is further described below with reference to the attached drawings and specific embodiments.

Examples

As shown in figures 1-3, the small electric boiler drainage device provided by the utility model comprises a high-precision liquid guide pipe 1, a slide valve 2 is sleeved on the outer ring of the high-precision liquid guide pipe 1, the high-precision liquid guide pipe 1 is in sliding connection with the slide valve 2, the high-precision liquid guide pipe 1 is in high-precision fit with the slide valve 2, a drainage hole 3 is formed in the high-precision liquid guide pipe 1, the slide valve 2 is in a closed state, the drainage hole 3 is positioned in the slide valve 2 when the slide valve 2 is in an open state, an inner groove 4 is formed in the inner ring of the slide valve 2, assembly grooves 5 are respectively formed in the two sides of the inner wall of the inner groove 4, flexible sealing rings 6 are arranged in the assembly grooves 5, one sides of the flexible sealing rings 6 are mutually attached to the outer ring of the high-precision liquid guide pipe 1, the flexible sealing rings 6 are correspondingly installed with the assembly grooves 5, and one sides of the flexible sealing rings 6 are fixedly connected with the slide valve 2 through the assembly grooves 5.

In this embodiment, when the slide valve 2 drives the flexible sealing ring 6 to axially move to the position shown in fig. 2, the drainage hole 3 is outside the sealing of the flexible sealing rings 6 at both ends, drainage stops, the high-precision liquid conduit 1 is restored to a normal conduction state, liquid in the conduit can normally flow, and the system normally works;

when the high-precision liquid conduit 1 realizes fluid conduction and flow and is provided with the drain hole 3, the two sides of the inner wall of the inner groove 4 are provided with the assembly grooves 5, and the flexible sealing rings 6 are arranged, when the slide valve 2 drives the flexible sealing rings 6 to be positioned in the position shown in fig. 3, the drain hole 3 is conducted with the outside, and fluid in the system is discharged due to potential and pressure difference, so that the function of quick discharge is achieved.

The above-described embodiment is only one preferred embodiment of the present utility model, and many alternative modifications and combinations of the above-described embodiments can be made by those skilled in the art based on the technical solutions of the present utility model and the related teachings of the above-described embodiments.
