Embodiment
Core of the present utility model is to provide a kind of device for detection of safety valve of water tank relieving characteristics, reduces labour intensity.
In order to make those skilled in the art person understand better the utility model scheme, below in conjunction with drawings and embodiments, the utility model is described in further detail.
Please refer to shown in Fig. 2-Fig. 6, the utility model embodiment discloses a kind of safety valve of water tank relieving characteristics proving installation, for detection of letting out end opening pressure and the end opening pressure that leaks in safety valve 5, comprise: air inlet cover plate 1, this air inlet cover plate 1 has inlet channel (not shown), the air intake opening 11 of inlet channel is connected with source of the gas, and gas outlet 12 is for being communicated with the entrance point of safety valve 5; Give vent to anger dull and stereotyped 2, this give vent to anger dull and stereotyped 2 have for in safety valve 5, let out that end is communicated with in let out passage (not shown) and hold with leaking of safety valve 5 the passage (not shown) that leaks being communicated with; Be connected with the flat board 2 of giving vent to anger, drive dull and stereotyped 2 drive units 3 away from described air inlet cover plate 1 of giving vent to anger; In control, let out passage break-make in let out solenoid valve.
During test, by drive unit 3, safety valve 5 is placed on to air inlet cover plate 1 and gives vent to anger and clamp between dull and stereotyped 2, and gas outlet 12 is communicated with the inlet end of safety valve 5, by in safety valve 5, let out end with in let out channel connection, leak end and the channel connection that leaks of safety valve 5, in opening, letting out solenoid valve, is then safety valve 5 inflation by source of the gas, until safety valve 5 in let out end and open and start pressure release; In closing again, let out solenoid valve, until the end that leaks starts pressure release, complete the detection of safety valve 5, by drive unit 3, discharge safety valve 5.In the application, avoid operator manual by letting out the process of end capping in safety valve 5, therefore, reduced operator's labour intensity.
Particularly, in the application, the lower surface of air inlet cover plate 1 (air inlet cover plate 1 and the dull and stereotyped 2 relative sides of giving vent to anger) and dull and stereotyped 2 the upper surface of giving vent to anger (dull and stereotyped 2 sides relative with air inlet cover plate 1 of giving vent to anger) opposing parallel is arranged, and by gas outlet 12 and in let out passage import 21 positioned opposite.By air inlet cover plate 1 and the flat board 2 of giving vent to anger are arranged in parallel, can prevent that safety valve 5 is not connected tight with air inlet cover plate 1 with the flat board 2 of giving vent to anger and leaks gas.To give vent to anger dull and stereotyped 2 and air inlet cover plate 1 be arranged in parallel, also can be convenient to the installation of safety valve 5, no longer need miscellaneous part to connect, provide cost savings.
In order further to prevent gas leakage between safety valve 5 and air inlet cover plate 1,12 places, gas outlet of the inlet channel in the pick-up unit providing in the application are provided with the first gasket seal (not marking in figure), setting by the first gasket seal can make to be tightly connected between safety valve 5 and inlet channel, thereby has improved the accuracy that this pick-up unit detects.Concrete shape for the first gasket seal need to coordinate with the inwall of inlet channel and the valve port place of safety valve 5, and further, this first gasket seal is elastic construction, is specially elastomeric material or polytetrafluoroethylmaterial material.
Further in embodiment, in interior import 21 of letting out passage, the second gasket seal is set, and at import 23 places of the passage that leaks, the 3rd gasket seal is set, to prevent that safety valve 5 and the junction of the flat board 2 of giving vent to anger from leaking gas.Sealing function by the second gasket seal and the 3rd gasket seal can improve the compactedness that safety valve 5 is connected, thereby further improves the detection accuracy of this pick-up unit.In like manner, the shape of this second gasket seal need to in the interior inwall of letting out passage and safety valve 5, let out end and coordinate, the shape of the 3rd gasket seal need to coordinate with the inwall of the passage that leaks and the end that leaks of safety valve 5, preferably, above-mentioned the first gasket seal, the second gasket seal and the 3rd gasket seal are annular gasket.And the second gasket seal and the 3rd gasket seal are elastic construction, are specially elastomeric material or polytetrafluoroethylmaterial material.
In practice interior outlet 22 of letting out passage is opened in to the side of the flat board 2 of giving vent to anger, and the outlet of the passage that leaks 24 is also opened in to the side of the flat board 2 of giving vent to anger.
Further, in embodiment, drive unit 3 is set to cylinder, and the expansion link of cylinder is connected with the flat board 2 of giving vent to anger.During work, the motion by Telescopic-cylinder bar can drive give vent to anger dull and stereotyped 2 near or away from air inlet cover plate 1, thereby realize clamping and releasing safety valve 5.It will be understood by those skilled in the art that; for drive unit 3, also can realize by linear electric motors; the core that drive unit 3 is set has been give vent to anger flat board 2 and 1 relative motion of air inlet cover plate, therefore, as long as the structures that can realize dull and stereotyped 2 motions of giving vent to anger are all in protection domain.
Preferably, drive unit 3 is set to move along the direction of the lower surface perpendicular to air inlet cover plate 1, by motion vertically, the dull and stereotyped 2 track sizes of moving that can reduce to give vent to anger, save energy.
On the basis of technique scheme, in the application, on air inlet cover plate 1, offered a plurality of gas outlets 12 that are communicated with air intake opening 11, and give vent to anger offer on dull and stereotyped 2 corresponding with gas outlet 12 numbers leak passage and in let out passage.The application by a plurality of gas outlets 12 are set, leak passage and in let out when passage can be realized a plurality of safety valve 5 and detect, improved greatly detection efficiency.
The air inlet cover plate 1 providing in the application is fixed support by support, and this support comprises base plate 41 and two risers 42 that are connected with base plate 41, and above-mentioned air inlet cover plate 1 is erected on two risers 42.In order to realize the movement of whole pick-up unit, above-mentioned drive unit 3 is arranged on base plate 41.Further, on riser 42, offered lightening hole 43, to reduce the weight of whole pick-up unit, also can save material simultaneously, reduced costs.
In order further to reduce labour intensity, in the application, also comprise the sensor of letting out passage pressure release and sending signal for detection of interior; For receiving the control device of letting out closed electromagnetic valve in signal control.During work, first in inciting somebody to action, letting out solenoid valve opens, so that in let out channel connection, then safety valve 5 is inflated, until in let out passage and start pressure release, now sensor receives signal and sends to controller, this controller is let out closed electromagnetic valve in controlling, in making, let out channel enclosed, then detect the end that leaks of safety valve 5.By sensor and control device are set, can realize the automatic control of solenoid valve, realize the robotization of device, reduce labour intensity.
In this instructions, each embodiment adopts the mode of going forward one by one to describe, and each embodiment stresses is the difference with other embodiment, between each embodiment identical similar part mutually referring to.
Above-mentioned explanation to the disclosed embodiments, makes professional and technical personnel in the field can realize or use the utility model.To the multiple modification of these embodiment, will be apparent for those skilled in the art, General Principle as defined herein can, in the situation that not departing from spirit or scope of the present utility model, realize in other embodiments.Therefore, the utility model will can not be restricted to these embodiment shown in this article, but will meet the widest scope consistent with principle disclosed herein and features of novelty.
