Description

Technical Field

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

[0002] The angle seat valve is a guided angle seat valve operated by a single-acting pneumatic actuator with spring safety protection. The angle seat valve is widely used in short-term frequent starts. Maintaining the flow rate can save space. It has the characteristics of sensitive response and accurate action. When used with a solenoid valve, pneumatic control can accurately control the flow of gas and liquid, and can achieve accurate temperature control, dripping liquid and other requirements.

[0003] When the existing angle seat valve transmits high-temperature media, the valve stem will directly contact the high-temperature media. At this time, the heat of the high-temperature media is easily transferred to the valve stem, causing the overheated valve stem to damage the components on the upper part of the angle seat valve.

[0004] The reason for this problem is that the current angle seat valve mainly opens and closes the valve channel by means of a valve stem that slides up and down. When transmitting high-temperature media, the valve stem will directly contact the high-temperature media, and the steel valve stem has high conductivity. At this time, the heat of the high-temperature media is easily transferred to the valve stem, causing the overheated valve stem to be transferred to the components on the upper part of the angle seat valve, causing damage to the components. In view of the shortcomings of the existing technology, we propose a heat dissipation angle seat valve to solve the above problems. Utility Model Content

Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] The embodiment of the present application provides a heat-dissipating angle seat valve, which solves the problem that when the current angle seat valve transmits high-temperature medium, the valve stem will directly contact the high-temperature medium. At this time, the heat of the high-temperature medium is easily transferred to the valve stem, causing the overheated valve stem to damage the components on the upper part of the angle seat valve.

[0022] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0023] The utility model embodiment discloses a heat dissipation type angle seat valve.

[0024] According to the attached Figure 1-3 As shown, a heat dissipation angle seat valve comprises an angle seat valve body 1 and a valve stem 101 arranged on the inner wall of the angle seat valve body 1, and heat dissipation components 2 are arranged on the inner and outer sides of the angle seat valve body 1, and the heat dissipation component 2 comprises an outer unit 201 and an inner unit 202;

[0025] The outer unit 201 includes a sealing ring 2021 and a heat absorbing filler 2022. The sealing ring 2021 is fixedly connected to the inside of the angle seat valve body 1, and the heat absorbing filler 2022 is arranged between two groups of sealing rings 2021;

[0026] The inner unit 202 includes a steel pipe 2011 , which is fixedly connected to the outer peripheral wall of the angle seat valve body 1 , and cooling water is arranged inside the steel pipe 2011 .

[0027] The specific functions of the angle seat valve body 1 can refer to the pneumatic high temperature resistant angle seat valve of model VATTEN.

[0028] A rod sleeve 102 is provided in the middle of the angle seat valve body 1, the valve stem 101 is movably connected to the inside of the rod sleeve 102, the steel pipe 2011 is fixedly connected to the outer peripheral wall of the rod sleeve 102, and a water cavity 2014 is provided between the steel pipe 2011 and the rod sleeve 102. Cooling water is provided inside the water cavity 2014. The temperature of the valve stem 101 can be absorbed by the cooling water to cool it down.

[0029] The sealing rings 2021 are fixedly connected to the ends of the rod sleeve 102 respectively, and the valve stem 101 passes through two sets of sealing rings 2021. The sealing rings 2021 can be made of a special high-temperature resistant composite graphite material, which can isolate and seal the high-temperature medium flowing in the lower part of the angle seat valve body 1, and can reduce the heat of the high-temperature medium introduced into the upper part of the angle seat valve body 1.

[0030] The heat absorbing filler 2022 is fixedly connected between the rod sleeve 102 and the valve stem 101. The heat absorbing filler 2022 is used to absorb the heat of the valve stem 101. The heat absorbing filler 2022 can be made of high-temperature resistant flexible graphite filler, which can further reduce the situation where heat is introduced into the upper part of the angle seat valve body 1.

[0031] The outer wall of the steel pipe 2011 is provided with a return pipe 2012 and an outlet pipe 2013. The return pipe 2012 is distributed above the outlet pipe 2013. The return pipe 2012 and the outlet pipe 2013 are used to circulate cooling water.

[0032] The end of the return pipe 2012 is externally connected to a cold water circulation pump, and the end of the outlet pipe 2013 is externally connected to a condenser. The cold water circulation pump and the condenser are connected to each other through a connecting pipe. The water in the water chamber 2014 will flow out from the outlet pipe 2013 in sequence and pass through the condenser and the cold water circulation pump, and then flow back to the water chamber 2014 from the return pipe 2012 to form a cycle. The water inside the steel pipe 211 can be recycled by the cold water circulation pump, and the water inside the steel pipe 211 can be re-cooled by the condenser after absorbing heat, so as to continuously absorb heat and cool the valve stem 101 in the angle seat valve body 1, and dissipate heat from the valve stem 101, thereby preventing the heat of the high-temperature medium from being easily transferred to the components on the upper part of the angle seat valve body 1 through the valve stem 101, causing component damage.

[0033] When the utility model is in use, while using the angle seat valve body 1 to transmit high-temperature media, the condenser externally connected to the water outlet pipe 2013 can cool the water after absorbing heat at the water outlet pipe 2013, and the cooled water is transported to the water cavity 2014 through the return pipe 2012 through the cold water circulation pump, so as to circulate and absorb the heat of the valve stem 101 in the steel pipe 2011.

[0034] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected.
