Description
Technical field
The utility model relates to a kind of solenoid valve, specifically refers to a kind of ultralow temperature electromagnetic valve.
Background technique
Ultralow temperature electromagnetic valve is a kind of solenoid valve for using under low temperature environment, is widely used in the refrigerant pipe systems such as space flight, boats and ships heavy industry, chemical industry, refrigeration equipment, food medical equipment.The structure of existing ultralow temperature electromagnetic valve generally all includes valve head and electromagnetic coil assembly, described valve head includes valve body, valve body is provided with feeding-passage, tapping channel and be arranged at feeding-passage, valve pocket between tapping channel, because the medium in valve head is all cryogenic media, therefore, the outer surface of valve head is often congealed into ice or frost, and electromagnetic coil assembly operationally often generates heat, these heats pass in the frost of the outer surface of valve head, it can be made to be melted into water, and these water melted are once be dropped on electromagnetic coil assembly, just likely the electromagnetic coil of its inside is intake, there is short trouble.
Summary of the invention
The purpose of this utility model is the shortcoming and defect existed to overcome prior art, and provides a kind of vibrational power flow reasonable, and prevents water droplet from falling ultralow temperature electromagnetic valve electromagnetic coil assembly making its fault that is short-circuited.
For achieving the above object, the technical solution of the utility model includes valve head and electromagnetic coil assembly, valve head includes valve body, valve gap, valve body is provided with feeding-passage, tapping channel and be arranged at feeding-passage, valve pocket between tapping channel, in described valve pocket, lifting is provided with piston valve core, one end that this feeding-passage communicates with valve pocket is provided with the seal valve seat be sealed and matched with piston valve core, the electromagnetic coil that described electromagnetic coil assembly includes assembly shell and is arranged in assembly shell, in described electromagnetic coil, lifting driving is provided with valve rod, described valve rod is extension valve rod, the outer end of this extension valve rod is arranged with valve rod and adds long-neck cover, the lower end of described extension valve rod extend in valve pocket, and this piston valve in-core is provided with the pilot hole being communicated with the upper and lower both ends of the surface of piston valve core, the lower end of described extension valve rod is provided with cone seal head, upper shed place of this cone seal head and pilot hole seals adaptation, this extension valve rod and the downward ejection of piston valve core is simultaneously linked, described valve rod adds long-neck cover and the side cover of electromagnetic coil assembly is provided with water proof dish.
By this setting, valve rod is arranged to extension valve rod, can pull open the distance between electromagnetic coil assembly and valve head thus, the heat that the work of minimizing electromagnetic coil assembly produces on the impact of valve head, thus reduces the generation of water droplet, in addition, by arranging water proof dish, when contingency has water droplet to drip, water droplet can be separated, prevent water droplet from directly dropping on electromagnetic coil assembly, the fault preventing electromagnetic coil water inlet short circuit occurs.
Further setting intracardiacly in the lower end surface of described piston valve core is provided with sealing block embedding slot, and in sealing block embedding slot, setting-in is fixedly installed the sealing block be sealed and matched with seal valve seat.By this setting, improve the sealing between piston valve core and seal valve seat.
Further setting is that described valve gap thread seal is fixedly connected on the upper-end surface of valve body.By this setting, make valve gap dismounting very convenient, be convenient to the installation of the piston valve core in valve pocket simultaneously.
Further setting is that described valve rod adds long-neck cover and is fixedly installed heat insulation base relative between water proof dish and assembly shell.By this setting, carry out heat insulation separation by between water proof dish and electromagnetic coil assembly, prevent the water proof dish of relative low temperature to be delivered on electromagnetic coil by low temperature, cause fault to occur.
In sum, the utility model has the advantages that reasonable in design, effectively prevent electromagnetic coil from meeting water droplet and short trouble.
Below in conjunction with specification drawings and specific embodiments, the utility model is described further.
