Description

Filter blowdown structure with weeping detects function

Technical Field

The utility model relates to a filter equipment technical field, in particular to filter blowdown structure with weeping detects function.

Background

The filter in the prior art is not generally provided with a leakage detection function, or the leakage detection device is complex in structure, high in cost and improved in space.

SUMMERY OF THE UTILITY MODEL

Not enough to prior art exists, the utility model aims to provide a can realize preventing during the equipment operation that the valve trouble or close not tight weeping in time report to the police filter blowdown structure with weeping detects the function.

In order to achieve the above purpose, the utility model provides a following technical scheme: the utility model provides a filter blowdown structure with weeping detects function, includes blowoff valve and the blowdown pipe that connects gradually with the filter, the blowdown pipe includes the three-way pipe of being connected with the blowoff valve, the first elbow of lower exit linkage of three-way pipe, first straight tube is connected to first elbow, first straight tube connection falls the U-shaped pipe, the second straight tube is connected to the U-shaped pipe, the minimum liquid level of falling the U-shaped pipe and the minimum liquid level parallel and level of blowoff valve, the vertical inductor long probe that stretches into in the first elbow that is provided with in the three-way pipe, still vertical being provided with the bottom in the three-way pipe is less than the inductor short probe of the minimum liquid level of falling the U-shaped pipe and blowoff valve, inductor long probe and the short probe of inductor are connection director respectively.

Preferably, the inverted U-shaped pipe is formed by connecting four right-angle bends.

Preferably, the distance from the end part of the short probe of the inductor to the lowest liquid level of the inverted U-shaped pipe or the blow-down valve is 30mm.

The utility model has the following advantages for prior art, when equipment filters if the machine is inside when small liquid flows out, need through the blowoff valve, the three-way pipe, first elbow, first straight tube and the long probe contact of inductor earlier, liquid triggers the switch-on signal this moment with the short probe contact of inductor when arriving the minimum liquid level of falling U-shaped pipe soon and gives the controller, controller suggestion weeping, prevent valve trouble or close not tight weeping when the equipment transports to the operation. Wherein, the long probe of the inductor and the short probe of the inductor both adopt liquid level inductors. The liquid leakage detection and alarm device has the advantages that the liquid leakage detection and alarm can be realized by utilizing the low-cost structural design.

Drawings

Fig. 1 is a perspective view of a filter blowdown structure with a liquid leakage detection function of the present invention.

In the figure: 1. a filter; 2. a blowoff valve; 3. a three-way pipe; 4. a first elbow; 5. a first straight pipe; 6. an inverted U-shaped tube; 7. a second straight pipe; 8. a sensor long probe; 9. the sensor is short of the probe.

Detailed Description

The present invention will be further explained with reference to the accompanying drawings.

As shown in figure 1, a filter 1 blowdown structure with weeping detects function, include blowoff valve 2 and the blowdown pipe that connects gradually with filter 1, the blowdown pipe includes three-way pipe 3 with blowoff valve 2 is connected, the first elbow 4 of lower exit linkage of three-way pipe 3, first elbow 4 connects first straight tube 5, first straight tube 5 connects the pipe 6 that falls down, the pipe 6 that falls down connects the second straight tube 7, the minimum liquid level of the pipe 6 that falls down is parallel and level with the minimum liquid level of blowoff valve 2, vertically in the three-way pipe 3 be provided with the inductor long probe 8 that stretches into in first elbow 4, still vertically in the three-way pipe 3 be provided with the bottom and be less than the inductor short probe 9 of the minimum liquid level of pipe 6 and blowoff valve 2, inductor long probe 8 and inductor short probe 9 are connection director respectively.

Preferably, the inverted U-shaped pipe 6 is formed by connecting four right-angle bends.

Preferably, the distance between the end part of the short sensor probe 9 and the lowest liquid level of the inverted U-shaped pipe 6 or the drain valve 2 is 30mm.

The utility model provides a 1 blowdown structure of filter with weeping detects function, drainage when normally wasing: liquid is through blowoff valve 2, three-way pipe 3, first elbow 4, first straight tube 5, the U-shaped pipe of falling 6 and second straight tube 7 toward arranging outward, and after a certain time, the inside pressurization of admitting air of machine is all extruded pipeline water, and there is a small amount of water remaining second straight tube 7 bottom this moment, and other blowoff valves 2, three-way pipe 3, first elbow 4, first straight tube 5 and the 6 departments of the U-shaped pipe of falling do not have water basically to remain, and the system does not detect the weeping during normal washing.

When equipment filters if the inside little liquid outflow that appears of machine, need through blowoff valve 2, three-way pipe 3, first elbow 4, first straight tube 5 and the 6 outward outflow of reverse U-shaped pipe, liquid contacts with inductor long probe 8 earlier, and liquid and the short probe 9 contact of inductor trigger the switch-on signal this moment give the controller when arriving the minimum liquid level of reverse U-shaped pipe 6 soon, and the controller suggestion weeping prevents that the valve trouble or closes not tight weeping when equipment moves. Wherein, the long sensor probe 8 and the short sensor probe 9 both adopt liquid level sensors. The connection between the sensor long probe 8 and the sensor short probe 9 and the controller is the prior art, and this embodiment is not described herein.

The liquid leakage detection and alarm device has the advantages that the liquid leakage detection and alarm can be realized by utilizing the low-cost structural design.

It is above only the utility model discloses a preferred embodiment, the utility model discloses a scope of protection does not only confine above-mentioned embodiment, the all belongs to the utility model discloses a technical scheme under the thinking all belongs to the utility model discloses a scope of protection.
