Description

Technical Field

[0001] The utility model relates to the technical field of electric valves, in particular to a heat dissipation type electric valve. Background Art

[0002] Electric valve is an automatic control element, which mainly controls the opening and closing action of the valve through electric actuator. Electric valve usually consists of two parts, the upper part is the electric actuator, and the lower part is the traditional valve structure. Electric valve can be used to control the flow of pipeline media such as liquid, gas, and wind system, and is also used for the control of large valves and wind systems to improve the operation quality.

[0003] After searching, the patent publication number CN206036384U discloses an electric valve, in particular, a heat dissipation electric valve, which belongs to the field of valve technology; the valve includes a valve body with an electric valve structure, the valve body includes an electric actuator and a valve, the electric actuator is connected to the valve through a valve stem, and a heat dissipation device is provided on the valve stem, the heat dissipation device includes a sleeve with bosses at both ends and used to connect the electric actuator and the valve, and a plurality of annular heat sinks arranged on the sleeve; a heat dissipation electric valve of the utility model solves the problem of electric actuator getting stuck under high temperature, and the design of the annular heat sink makes the valve body dissipate heat quickly, and at the same time effectively alleviates the influence of high temperature on the precision components of the valve body, thereby improving the service life of the electric valve.

[0004] However, this patent still has some shortcomings. This patent only dissipates heat through heat sinks, which is a relatively simple heat dissipation method with poor heat dissipation effect. In addition, the electric actuator in this electric valve does not have a heat dissipation structure, so it is easy to cause the electric actuator to overheat and be damaged. At the same time, the electric valve has no manual adjustment function. Once the electric actuator fails, the valve size cannot be adjusted, which easily affects the use of the valve.

[0005] In order to solve the above problems, we propose a heat dissipation electric valve. Utility Model Content

[0027] A transmission rod 13 is rotatably connected to the right side of the column 21 in the mounting plate 2, and the left end of the transmission rod 13 is fixedly mounted on the bevel gear 12. This design is conducive to the use of this electric valve. The right side of the transmission rod 13 extends out of the mounting plate 2. A crank 14 is fixedly mounted on the right side of the transmission rod 13, and the crank 14 is convenient for driving the transmission rod 13 to rotate. A card seat 10 is fixedly mounted on both sides of the electric actuator 3, and the two card seats 10 are plugged into the fixing frame 4. This design is conducive to the use of this electric valve.
