Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of plunger valves, in particular to a plunger valve with a heat preservation function. Background Art
[0002] In many fields such as industrial production, petrochemicals, and pharmaceuticals, plunger valves are important fluid control equipment, and their performance stability and reliability are crucial to the normal operation of the production process. However, in low temperature environments, fluid media are prone to solidification or crystallization, which not only affects the normal opening and closing of the plunger valve, but may also cause equipment damage or even production accidents.
[0003] In terms of heat preservation, the traditional plunger valve is usually covered with cotton cloth or other similar insulation materials on its outer surface. However, this simple insulation method has obvious limitations. First, the insulation effect is not ideal, and it is often difficult to effectively prevent heat loss, especially in extremely low temperature environments. Secondly, this insulation method is easily affected by the external environment, such as wind and humidity, which further weakens its insulation effect. In addition, as the use time increases, the insulation material may age, break, and other problems, further reducing the insulation performance. Utility Model Content

[0005] In view of this, the purpose of the utility model is to provide a plunger valve with a heat preservation function to solve the problems raised in the above background.
[0006] (II) Technical solution
[0007] A plunger valve with a heat preservation function comprises a plunger valve body, two groups of mounting rings are fixedly installed on the outer surface of the plunger valve body, and the two groups of mounting rings are far away from each other, multiple groups of heating rods are arranged between the two groups of mounting rings, and a first heat preservation shell and a second heat preservation shell are respectively installed on the outer surfaces of the two groups of mounting rings, the first heat preservation shell and the second heat preservation shell are both fixedly installed on the outer surfaces of the first heat preservation shell and the second heat preservation shell, and multiple groups of screw holes are provided on the outer surfaces of the connecting plates, and screws are installed in the multiple groups of screw holes.
[0008] Preferably, the inner walls of the first insulation shell and the second insulation shell are provided with cavities, and the interior of the cavities is filled with insulation cotton. Due to the insulation effect of the insulation cotton, the heating time and power of the heating rod can be reduced, thereby reducing energy consumption and significantly reducing operating costs. The insulation cotton can also protect the plunger valve body from extreme temperatures, thereby extending its service life.
[0009] Preferably, seals are fixedly installed at both upper and lower ends of the first insulation shell and the second insulation shell, and the outer surface of the seal is wrapped with rubber. The installation of the seal can effectively prevent the entry of external cold air, reduce the exchange of heat with the external environment, thereby enhancing the thermal insulation performance of the insulation shell. The rubber material also has good wear resistance and corrosion resistance, which can ensure that the seal is not easily damaged during long-term use, thereby enhancing its durability.
[0010] Preferably, the outer surfaces of the two groups of mounting rings are provided with a plurality of connection grooves, and the plurality of connection grooves serve as a limiting connection for the first insulation shell and the second insulation shell.
[0011] Preferably, multiple groups of connecting pins are fixedly installed on the inner walls of the first insulation shell and the second insulation shell, and the multiple groups of connecting pins cooperate with the multiple groups of connecting grooves to facilitate the initial connection of the insulation shells and increase the firmness and stability during installation.
[0012] Preferably, one end of the plurality of groups of connecting pins is in an arc shape, and the connecting pins are made of magnet material, so that the connecting pins at the arc-shaped end can be more easily inserted into the connecting slot, thereby simplifying the installation process. At the same time, the connecting pins are made of magnet material, and the adsorption force of the magnet can further ensure the tightness of the connection, while also facilitating disassembly.
[0013] Preferably, the outer surface of one side of the first insulation shell and the second insulation shell is made of ceramic material. Ceramics have good thermal insulation properties, can reduce heat loss, and also have wear resistance, corrosion resistance and other properties, so that the insulation shell is not easily damaged during long-term use and can maintain a long service life.
[0014] It can be seen from the above technical solutions that the present application has the following beneficial effects:
[0015] 1. The utility model installs heating rods evenly distributed on the outer surface of the plunger valve body, which can ensure that the heat generated by the heating rods can be transferred to the plunger valve body in a low temperature environment, thereby effectively preventing the fluid medium from solidifying or crystallizing due to excessively low temperature. This ensures that the plunger valve can still be opened and closed normally in a low temperature environment, and improves its working stability and reliability.
[0016] 2. The utility model provides an additional insulation layer for the plunger valve through the design of the first insulation shell and the second insulation shell. These insulation shells have good insulation performance and can effectively reduce the loss of heat to the external environment, thereby significantly enhancing the insulation effect of the plunger valve.
