Abstract
The utility model relates to a kind of rain covers for waste heat boiler motor-driven valve, the rain cover is in mushroom-shaped, including cover and it is fixed on the bracket of cover bottom, the bracket includes the connection frame of the bottom circular lasso parallel with cover and the multiple straight rod types being connected between lasso and cover.Compared with prior art, the utility model structure is simple, and manufacturing cost is cheap, solves the problems, such as that motor-driven valve exposes to the sun and rain, it is ensured that its long-term, safe and stable, reliability service；Meanwhile also it can accelerate motor-driven valve internal steam by installation micro motor and fan and fall in the evaporation rate of the rainwater of electronic valve surface once in a while.
Description
Technical field
The utility model relates to boiler technology fields, and in particular to a kind of rain cover for waste heat boiler motor-driven valve.
Background technique
Motor-driven valve is briefly exactly with electronic actuator control valves door, to realize the on and off of valve.It can be divided into
Upper and lower two parts, top half are Electric Actuator, and lower half portion is valve.In afterheat boiler system, motor-driven valve it is exposed
Outdoor mounted occurs motor-driven valve power supply air switch several times and trips without reason, through malfunction elimination, be judged as during O&M
Electric control valve is drenched with rain after dampness, and power switch is caused to trip, and is given equipment stable operation and has been buried security risk.In addition, existing
Some motor-driven valve shields mostly use totally-enclosed or semi-enclosed structure, i.e., Electric Actuator are completely encapsulated in shield.
Such design has following defect: the steam that motor-driven valve evaporates during the water of conveying can enter at the top of screw rod, due to
The totally-enclosed or semiclosed shield at top, this part steam can not be discharged in time, and screw rod is caused to be corroded.
Utility model content
The purpose of this utility model is exactly to provide a kind of open to overcome the problems of the above-mentioned prior art
Rain cover for waste heat boiler motor-driven valve.
The purpose of this utility model can be achieved through the following technical solutions: a kind of for the anti-of waste heat boiler motor-driven valve
Canopy, the rain cover including cover and are fixed on the bracket of cover bottom, the bracket includes bottom and cover in mushroom-shaped
The connection frame of the parallel circular lasso of body and the multiple straight rod types being connected between lasso and cover.The utility model is prevented
Cover is placed on motor-driven valve overhead electric actuator by canopy by connection frame and lasso, since lasso and connection frame all use
Thin metal rod bending is welded, and is consequently belonging to the structure of full open model, on the basis of effectively keeping off the rain, will not influence electricity
The volatilization of dynamic valve internal steam.
Multiple connection frames are greater than motor-driven valve overhead electric to the inclined distribution in cover center, the area of the lasso
The area of section of actuator.The design both can guarantee that rain cover can be quickly inserted in, and also can guarantee at the top of rain cover and motor-driven valve
It is maintained a certain distance at the top of Electric Actuator.
Preferably, the quantity of the connection frame is 3~6.
The fan that cover bottom is equipped with micro motor and connect with micro motor, fan face motor-driven valve top electricity
Dynamic actuator.Be arranged fan, on the one hand can accelerate the volatilization of motor-driven valve internal steam, on the other hand, can accelerate not by
The evaporation (such case typically occur in wind big in the case where) of the rainwater blocked completely.
The top of the cover is equipped with solar energy photovoltaic panel, and the bottom of cover is equipped with battery, the solar energy photovoltaic panel
It is connect by solar controller with battery, the micro motor is connect with battery, is miniature by solar energy photovoltaic panel
Motor provides electric energy, avoids or reduces the use of electric energy.
The cover periphery is equipped with the cover eaves being turned over downwards.
Compared with prior art, the beneficial effects of the utility model are embodied in following several respects:
(1) structure is simple, and manufacturing cost is cheap, solves the problems, such as that motor-driven valve exposes to the sun and rain, it is ensured that its long-term, safety,
Stablize, reliability service；
(2) setting for passing through micro motor and fan, can accelerate motor-driven valve internal steam and fall in motor-driven valve once in a while
The evaporation rate of the rainwater on surface；
(3) by solar energy photovoltaic panel and battery, the loss of electric energy is reduced.
Detailed description of the invention
Fig. 1 is structural schematic diagram when rain cover is put upside down in embodiment 1；
Fig. 2 is the side view of rain cover in embodiment 2.
Wherein, 1 is cover, and 11 be cover eaves, and 2 be bracket, and 21 be lasso, and 22 be connection frame, and 4 be solar energy photovoltaic panel, and 4 are
Solar controller, 5 be battery, and 6 be micro motor, and 7 be fan.
Specific embodiment
It elaborates below to the embodiments of the present invention, the present embodiment before being with technical solutions of the utility model
It puts and is implemented, the detailed implementation method and specific operation process are given, but the protection scope of the utility model is unlimited
In following embodiments.
Embodiment 1
A kind of rain cover for waste heat boiler motor-driven valve, structure is as shown in Figure 1, including cover 1 and being fixed on cover
The bracket 2 of 1 bottom of body, bracket 2 include the bottom circular lasso 21 parallel with cover and be connected to lasso 21 and cover 1 it
Between 4 straight rod types connection frame 22.4 connection frames 22 are greater than electronic to the inclined distribution in 1 center of cover, the area of lasso 21
The area of section of valve overhead electric actuator, but the area that circle is formed by the top of 4 connection frames 22 is less than electricity at the top of motor-driven valve
The area of section of dynamic actuator, in this way, 4 are stuck in the top of motor-driven valve overhead electric actuator with the middle part of connection frame 22,
So that rain cover is fixed on the top of motor-driven valve overhead electric actuator.
Embodiment 2
Using structure similar to Example 1, the difference is that:
1 edge of cover of the present embodiment is equipped with the cover eaves 11 being turned over downwards；
The top of cover 1 is equipped with solar energy photovoltaic panel 3, and the bottom of cover 1 is equipped with battery 5, micro motor 6 and fan 7,
Solar energy photovoltaic panel 3 is connect by solar controller 4 with battery 5, and micro motor 6 is connect with battery 4, and fan 7 is installed
In the shaft of micro motor 6, and face motor-driven valve overhead electric actuator.
