Abstract
The utility model relates to a kind of worm wheel heads with gas detection alarm function, including shell, worm gear mechanism, cap, worm gear mechanism is installed in shell, shell is sealed by cap, and a support is fixedly mounted in housing sidewall, is fixedly mounted with a detector on the support, a sensor is connected in detector lower end, a combined aural and visual alarm is fixedly mounted at the top of cap, combined aural and visual alarm is connect with detector, detector and the wired or wireless connection of middle control DCS system.This worm wheel head increases inflammable or toxic gas detection function under the action of guaranteeing traditional function, ensure that safe operation when operator acts valve at the scene.
Description
Technical field
The utility model belongs to valve field, is related to worm wheel head, especially a kind of snail with gas detection alarm function
Wheel head.
Background technique
Worm wheel head is the mechanism of control valve unlatching and rate-of flow, is widely used in the row such as electric power, pharmacy, Chemical Manufacture
Industry.But it is revealed at the filler or valve flanges mouth of valve rod since valve often will appear in the long-term use, if pipeline
Interior process gas is combustion gas or toxic and harmful gas, causes site environment to be in unsafe condition, cannot such as find in time, can
The malignant event of personnel's poisoning or Fire explosion can be caused to occur.Traditional worm wheel head only has switching function without revealing function of alarming
Can, and the valve body-side of some valves is equipped with warning device, but closer due to installing with valve body, if valve circulation medium is height
Temperature or cryogenic media, then alarm easily damages and ineffective.
Utility model content
The purpose of the utility model is to overcome in place of the deficiencies in the prior art, provide one kind to guarantee production safety
Worm wheel head with gas detection alarm function.
The utility model technical scheme applied to solve the technical problem is:
A kind of worm wheel head with gas detection alarm function, including shell, worm gear mechanism, cap, in shell
Worm gear mechanism is installed, shell is sealed by cap, and a support is fixedly mounted in housing sidewall, is fixedly mounted with gas inspection on the support
Device is surveyed, a sensor is connected in detector lower end, a combined aural and visual alarm, combined aural and visual alarm and gas is fixedly mounted at the top of cap
Detector connection, detector and the wired or wireless connection of middle control DCS system.
Moreover, one waterproof cover of spiral-lock outside detector.
Moreover, being equipped with sealing joint strip between support and waterproof cover bottom surface.
Moreover, detector connects with sensor card load.
Moreover, the sensor is toxic and/or combustible gas sensor.
The advantages and positive effects of the utility model are as follows:
1, this worm wheel head increases inflammable or toxic gas detection function under the action of guaranteeing traditional function, ensure that operation
Personnel act safe operation when valve at the scene.
2, this worm wheel head has sound and light of alarm, can intuitively reflect the presence or absence of valve leak condition, avoids existing
Kindling, poisoning, explosive event generation occur in the construction process for field personnel.
3, leakage alarm signal can be transmitted to DCS system by this worm wheel head, and operator can monitor valve on-line and let out
Reveal situation, ensure that production safety.
4, detector is mounted on worm wheel head side, not only prevent because the temperature of processing medium is too high or it is too low due to cause
The generation of detector failure, and ensure that the operating distance of sensor distance valve rod, achieve the purpose that accurate alarm.
Detailed description of the invention
Fig. 1 is the main view of this worm wheel head；
Fig. 2 is the top view of Fig. 1.
Specific embodiment
The utility model is described in further detail with reference to the accompanying drawing and by specific embodiment, and following embodiment is only retouched
The property stated, it is not restrictive, protection scope of this utility model cannot be limited by this.
A kind of worm wheel head with gas detection alarm function, including shell 2, worm gear mechanism, cap 1, support 7,
Combined aural and visual alarm 5, detector 3 and sensor 6, install worm gear mechanism in shell, and shell is sealed by cap.?
It is fixedly mounted with a support on the side wall of shell, is fixedly mounted with a detector on the support, connects a sensor in detector lower end,
One waterproof cover 4 of spiral-lock outside detector.A combined aural and visual alarm, combined aural and visual alarm and detector are fixedly mounted at the top of cap
Connection, detector and the middle excellent wired or wireless connection of control DCS system.
Sealing joint strip is installed between support and waterproof cover bottom surface.
Replacement and verification to guarantee sensor is convenient, and detector connects with sensor card load.
The sensor is carbon monoxide, hydrogen sulfide and the three-in-one gas detection sensor of fuel gas.
The application method of this worm wheel head are as follows:
It is leaked at the flange or valve rod of valve, gas leakage will be detected by sensor, and be transferred to gas
Analysis in detector, when leakage concentration reaches alarming value, combined aural and visual alarm can issue alarm, while alarm signal is transferred to
DCS system reminds staff to check or overhaul.
Above-described is only preferred embodiments of the present invention, it is noted that for the ordinary skill of this field
For personnel, under the premise of not departing from utility model design, various modifications and improvements can be made, these belong to this reality
With novel protection scope.
