Abstract
The utility model relates to a pipeline automatic pressure relief device which comprises a water pump and a main pipeline, wherein an electro connecting pressure gauge and a pressure relief side pipe are arranged on the main pipeline, an electromagnetic valve is arranged on the pressure relief side pipe, and the electromagnetic valve conducts starting and closing motion according to an electric signal which is sent by the electro connecting pressure gauge. The electromagnetic valve which is communicated with and controlled by the electro connecting pressure gauge is arranged on the main pipeline so as to achieve pipeline automatic pressure relief, so that a phenomenon that pressure in a water pipe is too high does not occur under the condition that a water discharging valve is closed or turned down, and damage on a pump and a pipeline due to too high water discharging pipe can be prevented effectively. Meanwhile, the pipeline automatic pressure relief device is simple in structure, little in investment, easy to automatically control, and convenient to maintain.
Description
Technical field
The utility model relates to a kind of pipeline pressure release device, relates to specifically the pipeline automatic decompression device that a kind of usefulness can reduce the outlet conduit internal pressure of pump.
Background technology
Pump often can run into the situation that flow need to be regulated in normal the use, mainly contain at present the method for two kinds of adjust fluxes, and a kind of rotating speed that uses converter technique to change motor reaches the purpose of adjust flux.Another kind is the purpose that reaches adjust flux by the valve that adjusts water pipe.Although use converter technique to come the size of adjust flux very advanced, adjust flux also is subject to the cost height well, and is difficult in maintenance, the high puzzlement of technical threshold.Although the size of control valve also can reach the purpose of adjust flux, when the valve of outlet pipe closes to a certain degree, cause easily the pressure in the outlet pipe excessive, pump and pipeline there are very large infringement.
Summary of the invention
The purpose of this utility model is for the deficiencies in the prior art part, a kind of pipeline automatic decompression device is provided, has simple in structure, little, the advantage that is easy to safeguard of investment, can reduce because the outlet pipe valve turns down or close the high pressure that produces at outlet pipe, can prevent effectively that pump and pipeline from causing damage because pipeline pressure is excessive.
For achieving the above object, the utility model has adopted following technical scheme: comprise water pump and trunk line, electro connecting pressure gauge and pressure release side pipe are housed on the trunk line, on the pressure release side pipe electromagnetic valve are housed, electromagnetic valve opens and closes action according to the signal of telecommunication that electro connecting pressure gauge sends.
When the registration of electro connecting pressure gauge reached the higher limit of setting, electromagnetic valve was opened, and the current in the trunk line flow out through the pressure release side pipe, so that the trunk line internal pressure reduces.Thereby reach the purpose that reduces the trunk line internal pressure.When manometric registration dropped to the lower limit of setting, closed electromagnetic valve guaranteed the pressure treatment safe condition in the trunk line.
Above-mentioned pressure release side pipe outlet has evacuated tube to lead to reservoir, thereby forms circulation line with trunk line.
As shown from the above technical solution, the utility model is by being subjected to the electromagnetic valve of electro connecting pressure gauge telecommunications control trunk line setting, realize the pipeline releasing pressure automatically, so that outlet valve is in the situation of closing or turning down, the too high phenomenon of outlet pipe internal pressure can not appear, can effectively prevent to reduce manual inspection because the outlet pipe hypertonia causes pump and Pipeline damage, reduce labour intensity; And simple in structure, investment is little, easily realizes automation control, and is easy to maintenance.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The specific embodiment
The utility model as shown in Figure 1, at the trunk line 1 of water pump 6 delivery ports arranged one pressure release side pipe 3 and electro connecting pressure gauge 2.Electromagnetic valve 4 is installed on the pressure release side pipe 3, and electro connecting pressure gauge 2 is for detection of trunk line 1 internal pressure situation of change, and according to the running that opens and closes of situation of change control electromagnetic valve 3.
3 outlets of pressure release side pipe are provided with the evacuated tube 31 of leading to reservoir 5, and trunk line 1, pressure release side pipe 3 form circulation line with evacuated tube 31, reservoir 5.
Its operating principle is as follows: when the registration of electro connecting pressure gauge 2 rises and reaches the higher limit of setting, electro connecting pressure gauge 2 sends the signal of telecommunication, by control circuit electromagnetic valve 4 is opened, current in the trunk line 1 are back in the reservoir 5 through pressure release side pipe 3, evacuated tube 31, so that trunk line 1 internal pressure reduces.Thereby reach the purpose that reduces the trunk line internal pressure.When the registration of electro connecting pressure gauge 2 dropped to the lower limit of setting, electro connecting pressure gauge 2 sent the signal of telecommunication, by control circuit electromagnetic valve 4 cut out, and guaranteed the pressure treatment safe condition in the trunk line.
