Description

Technical Field

[0001] The utility model belongs to the technical field of valve manufacturing, and particularly relates to an anti-condensation air-conditioning ball valve. Background Technique

[0002] With the continuous improvement of people's living standards and the progress of social development, the requirements for the environment and temperature in office buildings, automatic factories, etc. are getting higher and higher, and the application of central air conditioners is also increasing. In addition, centralized heating in northern regions has become a basic requirement in modern cities and rural areas. The types and quantities of valves required for central air conditioners and centralized heating pipelines have also increased significantly.

[0003] Central air conditioners and heating generally require heat preservation of pipelines. On the one hand, it is to ensure that there is not too much energy loss of heat medium and refrigerant during transportation and to meet the indoor temperature requirements; on the other hand, it is to prevent the surface of the medium transportation pipeline from generating condensed water and affecting the production, living or office environment.

[0004] At present, the height of the handle or handwheel of most valves from the center of the pipeline has a relatively small radius, resulting in the handle being wrapped by the heat preservation layer of the pipeline and affecting the opening and closing operations of the valve. To solve this problem, it is decided to develop an anti-condensation air-conditioning ball valve. Summary of the Invention

[0005] The purpose of the utility model is to provide an anti-condensation and multi-functional anti-condensation air-conditioning ball valve for the above problems existing in the prior art.

[0006] The purpose of the utility model can be achieved by the following technical solutions: an anti-condensation air-conditioning ball valve, including a valve body, a valve cap is threadedly installed on the right side of the valve body, a valve seat is fixedly installed at the center of the inner cavity of the valve body, a valve ball is installed in the inner cavity of the valve seat, a valve rod is installed through the top of the valve body, a protective sleeve is threadedly sleeved on the outer surface of the valve rod at the top of the valve body, a handle is fixedly installed at the top of the valve rod, a locknut is threadedly sleeved above the handle at the top of the valve rod, the bottom of the valve rod penetrates to the inner cavity of the valve body and inserts into the top of the valve ball, an installation shell is fixedly installed at the bottom of the valve body, air blowing components are fixedly installed on both the front and rear sides of the inner cavity of the installation shell, the air blowing component includes an air blowing pipe, and a heating component is fixedly installed at the bottom of the inner cavity of the installation shell, and the heating component includes a threaded cylinder and an electric heating rod.

[0007] This anti-condensation air-conditioning ball valve mainly increases the distance between the switch handle of the ball valve and the valve center line, and designs the part between the valve body and the handle to be larger than the thickness of the pipeline insulation layer. On the one hand, it lengthens the length of the valve stem, and on the other hand, the neck of the valve body that wraps the valve stem adopts a split design. The valve is designed as a pull-rod structure. When necessary, the neck valve stem sheath can be removed, the valve stem and the handle can be taken off while the valve is in the closed state, and the valve cap is in the closed state, so it can be used as a lockable ball valve.

[0008] In the above-mentioned anti-condensation air-conditioning ball valve, a locking groove is opened at the top of the valve body at the position of the valve stem, and an O-ring is arranged between the connection of the valve stem and the top of the valve body. By setting the O-ring, the sealing performance between the valve stem and the valve body can be guaranteed, and the sealing effect during the use of the valve can be effectively ensured.

[0009] In the above-mentioned anti-condensation air-conditioning ball valve, the blow pipes are respectively communicated with the front and rear sides of the valve body, and an electric heating column is fixedly installed in the inner cavity of the blow pipe. The heating column can heat the gas inside the blow pipe and transport it to the inside of the valve ball to realize preheating of the inside of the valve ball.

[0010] In the above-mentioned anti-condensation air-conditioning ball valve, one end of the blow pipe is communicated with the inner cavity of the valve body, the other end of the blow pipe is fixedly installed with an air valve, the surface of the air valve is fixedly installed with a micro air pump, the air outlet end of the micro air pump is communicated with the air valve, and the air outlet end of the micro air pump penetrates to the outside of the installation shell. The micro air pump can suck in external gas and pump it into the blow pipe for heating. At the same time, a dust-proof net is arranged at the air inlet end of the micro air pump to prevent external dust from entering the valve.

[0011] In the above-mentioned anti-condensation air-conditioning ball valve, the threaded cylinder is fixedly installed at the bottom of the valve body, a threaded cap is threadedly sleeved on the surface of the threaded cylinder, and an electric heating rod is fixedly installed in the inner cavity of the threaded cap. The threaded cap can fix the electric heating rod on the threaded cylinder to realize quick installation. When disassembling, only need to unscrew the threaded cap from the surface of the threaded cylinder.

[0012] In the above-mentioned anti-condensation air-conditioning ball valve, a heating cavity is opened at the bottom of the valve ball, and the top of the electric heating rod extends into the heating cavity. By setting the heating cavity, the heated gas by the electric heating rod can be dispersed into the inside of the valve ball to realize uniform heating of the outside of the valve ball.

[0013] In the above-mentioned anti-condensation air-conditioning ball valve, a heat-insulating layer is arranged on the inner wall of the valve body, and a gasket is arranged between the inner cavity of the protective sleeve and the top of the valve body. By setting the gasket, the sealing performance of the connection between the protective sleeve and the valve body can be guaranteed.

[0014] Compared with the prior art, the advantages of this anti-condensation air-conditioning ball valve are:

[0015] 1. Adopt a high-neck design to increase the distance between the switch handle of the ball valve and the valve center line, and the design between the valve body and the handle is larger than the thickness of the pipeline insulation layer.

[0016] 2. The high-neck design is on the one hand to lengthen the length of the valve stem, and on the other hand, the neck of the valve body that wraps the valve stem part adopts a split design. The neck is separated from the valve body and is connected by a threaded connection, which is convenient for forging and processing of the blank.

[0017] 3. The valve opening and closing position limiting device is designed on the middle hole of the valve body, and the limiting device and the valve body are of an integral structure; it is processed and formed by stamping.

[0018] 4. The valve is designed as a pull-rod structure. When necessary, the neck valve stem sheath can be removed with the valve in the closed state, the valve stem and the handle can be taken off, and the valve cap is in the closed state, and it can be used as a lockable ball valve.

[0019] 5. A heating structure is provided at the bottom of the valve, which can ensure a constant temperature of the valve body in low-temperature situations and effectively prevent the valve from condensing. Description of the Drawings
