Abstract
The utility model provides a check valve with a detection function, which solves the technical problems that inspection can be conducted only after a steam trap is dismounted for judging whether the steam trap is good or not, while the steam trap is integral and is difficult to dismount. The check valve is characterized in that a circular samarium-cobalt magnet is sleeved and fixed at the root of a guide post of a valve clack to ensure that the circular samarium-cobalt magnet can move with the valve clack; the check valve comprises a detection device; and the detection device is formed by a return circuit consisting of a reed pipe, a lamp bead and a lamp bead power supply, and is arranged on an external wall of a valve body of the check valve. The check valve has the positive benefits that the steam trap can be detected without being dismounted, and the detection device can be used for detecting all the steam traps particularly when the steam trap in the check valve and the detection device are in a split type.
Description
Technical field
The utility model relates to a kind of safety check, is specifically to have the safety check that detects the STEAM TRAP fault.
Background technique
STEAM TRAP is contained in steam heated pipeline terminal, and its effect constantly is discharged into steam-heated ducted condensed water outside the pipeline.After steam enters pipeline, because meet the cold water that becomes of tube wall, flow in the STEAM TRAP, STEAM TRAP is met steam and is closed; When being arranged, condensed water can open discharging when running into automatically.After water racks up, follow out be high-temperature steam the time, can close immediately.Because after having adorned STEAM TRAP, steam-heated equipment can heat up rapidly.The normal working state of STEAM TRAP is the intermittent type draining.In order to prevent or reduce the counterpressure on drip pipe road, safety check is installed in the downstream of the STEAM TRAP of being everlasting at present.Safety check is made up of flap, flap guide cover and the spring of valve body (valve seat), band guide pillar.Correspondingly the normal working of safety check also is the intermittent type draining.
The STEAM TRAP common faults has following two kinds: 1, STEAM TRAP is stopped up: because impurity causes the obstruction of STEAM TRAP drain opening in the backwater, this fault can cause STEAM TRAP normally not discharge condensed water, and the moisture that carries in the steam can not fully be separated influences quality of steam.2, steam trap leakage: reason such as aging or corrosion causes steam trap leakage owing to the STEAM TRAP internals, this fault can cause STEAM TRAP not stopped to condensed water reclaim line discharged steam, not only the energy is caused waste, also can increase condensed water reclaim line internal pressure, the proper functioning of other condensed water recovery plant on the pipeline is impacted.Usually judge after the STEAM TRAP quality can only be taken STEAM TRAP apart to check, and STEAM TRAP is integrated type, not quick detachable, so erroneous judgement occurs or check the appearance of situation such as untimely through regular meeting.
Summary of the invention
For solving the problems of the technologies described above, the purpose of this utility model provides a kind of safety check with measuring ability.It is installed in the downstream of STEAM TRAP, can detect the STEAM TRAP fault.
The purpose of this utility model is achieved in that it comprises the flap of being with guide pillar, it is characterized in that: ring SmCo magnet (can 700 ℃ of not demagnetizations of following proper functioning) is enclosed within the guide pillar root of flap and fixing, makes the ring SmCo magnet can be mobile in the lump with flap; It also comprises detection device, and detection device constitutes the loop by dry reed-pipe, lamp pearl and lamp pearl power supply to be formed, and detection device is arranged on the check valve body outer wall, and particular location is defined as, and when flap opens or closes, can make the closed or disconnection of dry reed-pipe of detection device.
If during STEAM TRAP fault-free proper functioning, the utility model is the intermittent type draining, and namely flap is alternately opened, closed, then ring SmCo magnet moves back and forth with flap, the dry reed-pipe of detection device is alternately closed, disconnects, and the lamp pearl replaces light on and off, and at this moment the normal fault-free of STEAM TRAP is described.If plugging fault has taken place STEAM TRAP, condensed water can not normally discharge, and safety check will be in normally off so; If the leakage fault has taken place STEAM TRAP, safety check will be in normally open so.At this moment dry reed-pipe is in normally closed or often opens, and the lamp pearl is normal bright or often go out.And then can judge that STEAM TRAP is stopped up or leakage.
Compared with prior art, good effect of the present utility model is: it does not need to dismantle STEAM TRAP, can detect STEAM TRAP.Particularly will work as STEAM TRAP in the utility model and detection device and make when split type, and can use detection device that all STEAM TRAP are done detection.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
It comprises the flap 5 of being with guide pillar, and ring SmCo magnet 3 is enclosed within guide pillar 51 roots of flap, by jump ring 4 ring SmCo magnet is stuck in guide pillar 51 roots of flap, makes the ring SmCo magnet can be mobile in the lump with flap; It also comprises detection device 2, detection device constitutes the loop by dry reed-pipe, lamp pearl 21 and lamp pearl power supply and forms (electrical schematic diagram slightly), and detection device is arranged on check valve body 1 outer wall, and particular location is defined as, when flap opens or closes, can make the closed or disconnection of dry reed-pipe of detection device.
If during STEAM TRAP fault-free proper functioning, the utility model is the intermittent type draining, and namely flap is alternately opened, closed, then ring SmCo magnet moves back and forth with flap, the dry reed-pipe of detection device is alternately closed, disconnects, and the lamp pearl replaces light on and off, and at this moment the normal fault-free of STEAM TRAP is described.If plugging fault has taken place STEAM TRAP, condensed water can not normally discharge, and safety check will be in normally off so; If the leakage fault has taken place STEAM TRAP, safety check will be in normally open so.At this moment dry reed-pipe is in normally closed or often opens, and the lamp pearl is normal bright or often go out.And then can judge that STEAM TRAP is stopped up or leakage.
Claims (2)
1. safety check with measuring ability, it comprises the flap of being with guide pillar, it is characterized in that: ring SmCo magnet is enclosed within the guide pillar root of flap and fixing, makes the ring SmCo magnet can be mobile in the lump with flap; It also comprises detection device, and detection device constitutes the loop by dry reed-pipe, lamp pearl and lamp pearl power supply to be formed, and detection device is arranged on the check valve body outer wall, and particular location is defined as, and when flap opens or closes, can make the closed or disconnection of dry reed-pipe of detection device.
2. according to the described safety check with measuring ability of claim 1, it is characterized in that: the said guide pillar root that ring SmCo magnet is fixed on flap is that jump ring is stuck in ring SmCo magnet the guide pillar root of flap.
