Abstract
The utility model discloses a vacuum test device suitable for no bottom valve water pump water tank, characterized by: mainly constitute by device box body, negative pressure valve, the negative -pressure ball body and floating ball liquid level switch. Device box body bottom and nos bottom valve water pump water tank top rigid coupling are switched on by a UNICOM festival, fix on the negative pressure valve on installing the box body mount pad, the negative -pressure ball body and floating ball liquid level switch set up in the negative pressure valve, floating ball liquid level switch fixes at the negative pressure valve top, and connection external equipment is drawn forth the festival through the wire UNICOM of installing on the casing to the wire. The utility model is a full signal detection of water tank water can be realized to the vacuum test device of no bottom valve water pump water tank, the sealed dual function of water tank negative pressure, and simple structure, convenient to use, a great deal of advantages such as processing low cost.
Description
Technical field
This utility model relates to a kind of Auto-drainage monitoring field, particularly relates to the vacuum checking device of a kind of water pump without bottom valve water tank.
Background technology
The novel water pump without bottom valve water tank of industrial and mining establishment and the application of some draining places is it is generally required to configure the full signal feedback device of water, and to controlling the part full signal of offer water after filling water for water tank, in prompting water tank, air is discharged, and has reached vacuum state in case.
After starting mode of pump, in negative pressure state in water tank, water tank steam vent needs to be sealed against air in time and is inhaled in water tank.
Existing vacuum checking device is generally located on inside water tank, and structure is complicated and changes inconvenience, and use cost is higher.
Utility model content
This utility model solves technical problem is that of problem: for the defect of above-mentioned existence, a kind of simple in construction, vacuum checking device easy for installation are provided, it is capable of in water tank vacuum detecting and signal feedback, can sealed negative-pressure valve communicating joint in time during the work of water pump evacuation, it is prevented that inside leakage air entrance water tank.
This utility model realizes the scheme that above-mentioned functions purpose adopts: a kind of vacuum checking device suitable in water pump without bottom valve water tank, its feature master is, is made up of device box body, negative pressure valve, negative pressure spheroid and floating-ball level switch.Bottom described device box body affixed with water pump without bottom valve tank top, turned on by a communicating joint, being fixed in device box body mounting seat on negative pressure valve, described negative pressure spheroid and floating-ball level switch are arranged in negative pressure valve, and described floating-ball level switch is fixed on negative pressure valve top.
Further, described negative pressure valve is provided with venthole, and negative pressure valve top and the bottom internal diameter is different.
Further, described negative pressure spheroid is ball.
Further, described floating-ball level switch selects low-voltage miniature ball float, and holding wire leads to the PLC control part of outside by device box body communicating joint.
The beneficial effect that a kind of vacuum checking device suitable in water pump without bottom valve water tank of this utility model realizes: can realize water tank vacuum detecting, simple in construction, it is convenient to install and change, with low cost, long service life etc..

Detailed description of the invention
In order to become apparent from that this utility model is further illustrated, describe in detail below in conjunction with concrete drawings and Examples.
Refer to Fig. 1, a kind of vacuum checking device suitable in water pump without bottom valve water tank, be mainly made up of device box body (1), negative pressure valve (2), negative pressure spheroid (4) and floating-ball level switch (3).Bottom described device box body, (5) are affixed with water pump without bottom valve tank top, turned on by a communicating joint (8), negative pressure valve (2) is fixed on device box body mounting seat (5), described negative pressure spheroid (4) and floating-ball level switch (3) are arranged in negative pressure valve (2), and described floating-ball level switch (3) is fixed on negative pressure valve (2) top.
Operation principle
Such as Fig. 2, after water tank fills water, water in water tank by negative pressure valve communicating joint (12) enter negative pressure valve, along with water level rise, under buoyancy negative pressure spheroid (4) in negative pressure cavity on move, when water level reaches apopore (10) position, the small floating ball (11) of floating-ball level switch (3) is upper to be moved, internal magnetic red switch connection, and external control part just can collect connection signal, can determine whether that in water tank, air drains, in vacuum state.
After starting water pump, in negative pressure state in water tank, water level decreasing in negative pressure valve, negative pressure spheroid (4) falls after rise bottom negative pressure cavity, and evacuation in water tank, under atmospheric pressure effect, negative pressure spheroid seals negative pressure valve communicating joint closely, stops air to suck in water tank.
A kind of vacuum checking device suitable in water pump without bottom valve water tank provided by the utility model, it may be achieved the full signal detection of Water in Water Tank, the dual function of water tank negative-pressure sealing, and simple in construction, easy to use, the plurality of advantages such as low processing cost.
Embodiment described above only have expressed a kind of embodiment of the present utility model, every carries out some changes according to technical spirit of the present utility model and modification belongs to protection domain of the present utility model.Therefore, this utility model scope of patent protection should be as the criterion with claims.
