[0002] FC valves are control components in fluid delivery systems, with functions such as shutoff, regulation, diversion, backflow prevention, pressure stabilization, diversion or overflow pressure relief. FC valves used in fluid control systems come in a wide variety of varieties and specifications, from the simplest shutoff valves to the various FC valves used in extremely complex automatic control systems. FC valves are needed in the oil extraction process.

[0003] Since the temperature of the oil extracted from the inside of the oil well is very high, usually between 60-80 degrees, and the deeper the well, the higher the temperature, and the oil valves used in the oil extraction pipeline working under long-term high temperature conditions will reduce the service life of the oil valves, there is an urgent need to provide a high-temperature resistant FC valve for oil extraction to solve the above problems. Utility Model Content

[0004] The technical problem to be solved by the present invention is to overcome the disadvantage of the above-mentioned prior art that the temperature of the oil extracted from the inside of the oil well is very high, usually between 60-80 degrees, and the deeper the well, the higher the temperature, and the oil valves used in the oil extraction pipeline will reduce the service life of the oil valves when working under high temperature for a long time, and provide a high-temperature resistant FC valve for oil extraction.

[0005] In order to solve the above technical problems, the present invention adopts a technical solution: to provide a high-temperature resistant FC valve for oil drilling, comprising a valve body, wherein a heat dissipation component is provided on the outer side of the valve body;

[0006] The heat dissipation assembly includes a first ring body and a second ring body fixedly arranged on the outer surface of the valve body, a refrigeration unit arranged between the first ring body and the second ring body, and heat dissipation fins arranged on the side of the refrigeration unit;

[0007] A heat sink is provided on the outer side of the heat dissipation fin.

[0009] A water inlet pipe is installed on the side wall of the first ring body, and a water outlet pipe is installed on the side wall of the second ring body.

[0010] The present invention is further configured as follows: the first ring body and the second ring body have the same structure, a liquid storage cavity is provided inside the first ring body, and a plurality of liquid outlet holes are provided in a circular array on the side wall of the liquid storage cavity.

[0011] The utility model is further configured as follows: the refrigeration unit comprises a conduit installed between the liquid outlet holes of the first ring body and the second ring body that are opposite to each other, and a heat absorption sleeve installed on the outer surface of the conduit.

[0012] The present invention is further configured as follows: there are multiple refrigeration units, and the multiple refrigeration units are distributed in a ring array with the center point of the valve body as the center of the circle.

[0013] The utility model is further configured as follows: the number of the heat dissipation fins is the same as the number of the refrigeration units, and each of the heat dissipation fins is located between two adjacent refrigeration units;

[0014] The side surfaces of the heat dissipation fins are provided with heat dissipation holes.

[0015] The utility model is further configured as follows: the heat dissipation member includes an arc-shaped plate arranged on the outside of the valve body, a heat conducting plate installed on the side wall of the arc-shaped plate, and an arc-shaped heat absorbing plate arranged on the inner side of the heat conducting plate;

[0016] There are four groups of heat sinks, and the four groups of heat sinks are cylindrically enclosed on the outside of the valve body, and slots and plug-in plates are respectively provided on the sides of the arc-shaped plates in two adjacent groups of heat sinks.

[0018] The beneficial effects of the utility model are as follows:

[0019] The utility model connects the external cooling pipe with the water inlet pipe through the heat dissipation component. When the valve body is working, the high-temperature oil circulating inside it transfers heat to the valve body, and the valve body transfers heat to the heat dissipation fins. The heat absorption sleeve absorbs part of the heat on the heat dissipation fins. The external cooling pipe transports the coolant to the liquid storage cavity of the first ring body, and then transports it to the interior of the multiple conduits through multiple liquid outlet holes to eliminate the heat on the heat absorption sleeve. The remaining heat is transferred to the heat conducting sheet in conjunction with the arc-shaped heat absorbing plate. Since one end of the heat conducting sheet extends through the outside of the arc plate, the heat on the heat conducting sheet is eliminated by the external air, thereby cooling the valve body and extending the service life of the valve body.

Preferably, flanges are installed at the ends of the water inlet pipe and the water outlet pipe to facilitate connection with external pipelines.

[0032] The first ring body 21 and the second ring body 22 have the same structure, and a liquid storage cavity 211 is provided inside the first ring body 21 . The side wall of the liquid storage cavity 211 has a plurality of liquid outlet holes 212 in a circular array.

[0035] The number of the heat dissipation fins 24 is the same as the number of the refrigeration units 23 , and each heat dissipation fin 24 is located between two adjacent refrigeration units 23 ;

[0036] A heat dissipation hole 241 is formed on the side of the heat dissipation fin 24 . Preferably, there are multiple heat dissipation holes 241 , which are evenly distributed on the side of the heat dissipation fin 24 .
