Abstract
The utility model relates to a safe valve open pressure detecting device, which comprises a first detecting branch, a valve, a detecting joint and a flume successively communicated with a detecting air supply. The first detecting branch is provided with an in series first reducing valve and a first pressure gauge, the first reducing valve is communicated with the detecting air supply, a second detecting branch is parallelly equipped between the detecting air supply and the valve, the second detecting branch is provided with an in series second reducing valve and a second pressure gauge, the second reducing valve is communicated with the detecting air supply and the valve is a selector valve. After adopting the conformation, whether the detected safe valve is qualified is capable of being detected without exchanging the detecting joint and the detection is convenient and high efficient.
Description
Technical field
The utility model relates to a kind of pick-up unit, especially relates to the opening pressure of safety valve pick-up unit.
Background technology
Some need the closed container of bearing certain pressure, for example need on lid such as radiator, pressure cooker or the chamber wall to install and to bear certain pressure and can prevent the safety valve that container inner pressure is too high again, when the pressure in the container reaches first pressure, the valve of safety valve is not opened, when the pressure in the container reaches second pressure (it is higher to compare first pressure), the decompression of the valve opening of safety valve.In order to guarantee the safe in utilization of closed container, need to carry out opening pressure of safety valve before the product export and detect.At present, opening pressure of safety valve is detected employing two covering devices, comprise the reduction valve, rain glass, valve, detection tabs and the tank that are communicated with the detection source of the gas successively on every covering device, the output pressure of the reduction valve of a covering device wherein is transferred to first pressure, the output pressure of the reduction valve of another set of device is transferred to second pressure.When detecting, safety valve is received respectively on the detection tabs on two covering devices, open valve, under the first pressure effect, do not emit bubble in the tank, under the second pressure effect, emit bubble in the tank, then this safety valve is specification product, and the safety valve that does not meet above-mentioned two kinds of testing results simultaneously is a substandard product.Utilize this opening pressure of safety valve pick-up unit to detect safety valve, need safety valve is installed in respectively on two detection tabs and detect, detect very inconveniently, detection efficiency is low.
The utility model content
The utility model purpose is to provide a kind of detection tabs, easy to detect, opening pressure of safety valve pick-up unit that detection efficiency is high need do not changed when detecting safety valve.
The purpose of this utility model is achieved through the following technical solutions:
A kind of opening pressure of safety valve pick-up unit of the utility model, comprise first detection branch, valve, detection tabs and the tank that are communicated with the detection source of the gas successively, this first detection branch has first reduction valve and first rain glass of series connection, this first reduction valve is communicated with this detection source of the gas, be parallel with second detection branch between this detection source of the gas and this valve, this second detection branch has second reduction valve and second rain glass of series connection, and this second reduction valve is communicated with described detection source of the gas; This valve is a reversal valve.
In above-mentioned basis, wherein:
Described reversal valve is provided with exhaust box.
At least be parallel with two detection tabs on the output terminal of described reversal valve.
Be parallel with three detection tabs on the output terminal of described reversal valve.
Be connected with second valve between the input end of each described detection tabs and the described reversal valve.
The output terminal of each described detection tabs is communicated with a described tank respectively.
The utility model compared with prior art, a kind of opening pressure of safety valve pick-up unit of the utility model, owing to be provided with two detection branch, by regulating the output pressure of two reduction valve on the detection branch, and switch by reversal valve safety valve is communicated with these two detection branch respectively, do not need to change detection tabs and just can detect whether tested safety valve is qualified, easy to detect, detection efficiency is high.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is further described.
Fig. 1 is the principle of work block diagram of a kind of opening pressure of safety valve pick-up unit of the utility model.
Wherein, arrow is represented airflow direction.
Embodiment
See also Fig. 1, a kind of opening pressure of safety valve pick-up unit of the utility model, first detection branch
1, second detection branch 2, reversal valve, three detection tabs and three tanks.
Be parallel with three detection tabs on the output terminal of this reversal valve, be connected with second valve between the input end of each this detection tabs and this reversal valve, the output terminal of each this detection tabs is communicated with a tank respectively.The noise that sends when reversal valve commutates when detecting in order to reduce is equipped with exhaust box on this reversal valve.
Certainly, the quantity of this detection tabs and second valve is not limited to three, can be provided with one or more according to the needs that detect; This reversal valve can be a hand-operated direction valve, also can be solenoid directional control valve.
Be example with the safety valve that utilizes a kind of opening pressure of safety valve pick-up unit of the utility model to detect on the radiator filler cap below, testing process illustrated:
1. adjust the output pressure of first reduction valve, make the first barometric reading equal the first air pressure 0.08Mpa;
2. adjust the output pressure of second reduction valve, make the second barometric reading equal the second air pressure 0.09Mpa;
3. automobile watering flap safety valve is installed on the detection tabs,
4. open second valve;
5. the adjustment reversal valve makes detection tabs be communicated with first detection branch, draws first testing result;
6. the adjustment reversal valve makes detection tabs be communicated with second detection branch, draws second testing result;
7. judge whether product is qualified: do not emit bubble in the first testing result tank, emitting bubble in the second testing result tank is specification product; If emitting in the first testing result tank and not emitting bubble in the bubble or the second testing result tank is substandard product.
Claims (6)
1. opening pressure of safety valve pick-up unit, comprise first detection branch, valve, detection tabs and the tank that are communicated with the detection source of the gas successively, this first detection branch has first reduction valve and first rain glass of series connection, this first reduction valve is communicated with this detection source of the gas, it is characterized in that: be parallel with second detection branch between described detection source of the gas and the described valve, this second detection branch has second reduction valve and second rain glass of series connection, and this second reduction valve is communicated with described detection source of the gas; This valve is a reversal valve.
