Abstract

The utility model discloses a freeze-proof pressure gage jointer, which adopts a three-way pipe (2). One way of the three-way pipe (2) is connected with a pressure gage (1), other two ways are downwards bent to take the shape of an inverted U, and respectively provided with stop valves (3 and 3a), and the bottom end of the three-way pipe is communicated with a medium transportation pipe line (4).In the utility model, the inverted U-shaped three-way pipe is communicated with the pressure gage and the medium transportation pipe line, so that the medium flowing through the U-shaped three-way pipe is in the flowing state, and does not influence the normal operation of the pressure gage. The medium in the flowing state is not static in the U-shaped three-way pipe, so that the medium are not frozen due to low air temperature, the hidden accident caused by frozen blockage or frost damage is eliminated, the problem that the system running is influenced caused by the frozen blockage or frost damage at the joint between the pressure gage and the medium transportation pipe line when the pressure gage is used in the lower air temperature is solved, and the production accident rate is reduced.

Description

The anti-freeze pressure meter short circuit

One, technical field

The utility model belongs to anti-freeze pressure meter, specifically is the short circuit of anti-freeze pressure meter and medium transport pipeline junction.

Two, background technology

Tensimeter is the common equipment of band press liquid delivery line, is used to show the pressure of pumped (conveying) medium, guarantees system safety operation.The anti-freeze pressure meter that uses is to be connected by a loop with the medium transport pipeline at present, between loop and the tensimeter stop valve is housed.In actual motion, because the medium in the loop do not flow, when temperature was low, the medium in the loop can be frozen and block, and makes the tensimeter cisco unity malfunction.Tensimeter can not accurately show the pressure of operational system or cushioning the crook by bursting by freezing, not only influence the ordinary production of system, and can cause serious industrial accident.

Three, summary of the invention

The purpose of this utility model is to provide a kind of anti-freeze pressure meter short circuit at the problems referred to above, solving tensimeter uses under the lower environment of temperature, because of freeze to be obstructed or the freezing problem that influences system's operation in the junction of tensimeter and medium transport pipeline, reduce the incidence of industrial accident.

The utility model is achieved through the following technical solutions: the anti-freeze pressure meter short circuit is a three-way pipe, and one of three-way pipe leads to and is connected with tensimeter, and other two lead to down, and bending is down " U " type, and stop valve is housed respectively, and the bottom is communicated with the medium transport pipeline.

The beneficial effect that the utility model is had compared with the prior art is: use the three-way pipe that is down " U " type to be communicated with tensimeter and medium transport pipeline in the utility model, make the medium in " U " type three-way pipe of flowing through down be flow state, do not influence manometric operate as normal; Because the medium of flow state is not static in " U " type three-way pipe, just can not freeze because of temperature is low yet, has eliminated because of freezing and be obstructed or freezing accident potential of causing.

Four, description of drawings

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is the prior art constructions synoptic diagram.

Among the figure: 1 tensimeter, 2 three-way pipes, 3,3a stop valve, 4 pipelines, 5 heat-insulation layers, 6 loops, 7 stop valves.

Five, embodiment:

The utility model is described in further detail below in conjunction with accompanying drawing:

Fig. 1 provides structural representation of the present utility model, as shown in Figure 1, the utility model is a three-way pipe 2 by the anti-freeze pressure meter short circuit, one of three-way pipe 2 leads to and is connected with tensimeter 1, other two logical being bent downwardly from both sides are down " U " type, on the limit of " U " type of falling stop valve 3 is housed, stop valve 3a is housed on another limit, the bottom is communicated with medium transport pipeline 4.During work,

stop valve

3,3a in opened condition, the medium in the pipeline flows in the three-way pipe 2 of " U " type of falling, and like this, neither influences manometric operate as normal, can not take place again that medium freezes in the three-way pipe 2 of " U " type of falling or the phenomenon of bursting by freezing.For the anti-freeze pressure meter short circuit can also can normally be used under the temperature condition of Han Qu or severe cold district extreme cold, can outside the anti-freeze pressure meter short circuit and with medium transport pipeline 4 correspondence positions, install heat-insulation layer 5 additional, with the anti-freezing and heat-insulating effect of further raising anti-freeze pressure meter short circuit.

Fig. 2 is the prior art constructions synoptic diagram, the anti-freeze pressure meter that uses is to connect tensimeter 1 by a loop 6 with being connected of medium transport pipeline 4 at present, between loop 6 and the tensimeter 1 stop valve 7 is housed, the problem of this structure is that the medium in the loop 6 does not flow, so environment temperature is one low slightly, medium will in pipe, freeze or at loop 6 places by bursting by freezing.

Claims

1, a kind of anti-freeze pressure meter short circuit, it is characterized in that: this short circuit is a three-way pipe (2), and one of three-way pipe (2) leads to and is connected with tensimeter (1), and other two lead to down, and bending is down " U " type, and stop valve (3,3a) is housed respectively, the bottom is communicated with medium transport pipeline (4).

2, anti-freeze pressure meter short circuit according to claim 1 is characterized in that: add heat-insulation layer (5) with medium transport pipeline (4) correspondence position outside the anti-freeze pressure meter short circuit.
