At present; the cold-producing medium using in refrigerating system is generally R22 or R410A; along with environmental requirement is more and more tighter; the environmental requirement of cold-producing medium is also had relatively high expectations; carbon dioxide is used more and more as the cold-producing medium of environment-friendly type; the pressure controller using at present, pressure and safety do not reach the desired protection effect of carbon dioxide refrigerant cold-producing medium.Topmost deficiency is that sealing effectiveness is bad, and water resistance is poor.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of good sealing effect is provided, and water resistance is excellent, and has the water proof type carbon dioxide refrigerant pressure controller of explosion-proof performance.
The technical scheme that realizes the utility model object is: a kind of water proof type carbon dioxide refrigerant pressure controller, comprises copper pipe, upper cover, appliance switch housing, cover plate, wire, reed, moving contact, fixed contact and a left side, the inserted sheet of right both sides, reed, moving contact and fixed contact are all positioned at appliance switch housing inner chamber, appliance switch housing skin has wrapped up a copper retainer plate, cover plate covers the opening part at appliance switch housing, one end of reed is connected with the inserted sheet in left side, the other end is connected with moving contact, fixed contact is positioned at moving contact below, and fixed contact is connected with the inserted sheet on right side, a left side, the inserted sheet of right both sides connects with corresponding wire respectively, also comprises limiting plate, push rod, reaction diaphragm and ferropexy circle, limiting plate is arranged on the outside of cover plate, the two ends of reaction diaphragm are clamped between limiting plate and upper cover and by ferropexy circle and are fixedly connected with upper cover with limiting plate, one end of push rod is fixedly connected with reaction diaphragm, the other end props up reed through after cover plate, the appliance switch housing outer race of being wrapped up by copper retainer plate has protecting sheathing, and appliance switch housing is positioned at protecting sheathing, and in protecting sheathing appliance switch housing above and side be all filled with epoxy resin.
Further, the junction of cover plate and appliance switch housing is provided with sealing ring.
Adopted technique scheme; the utlity model has following beneficial effect: because the appliance switch housing outer race of being wrapped up by copper retainer plate has protecting sheathing; appliance switch housing is positioned at protecting sheathing; and in protecting sheathing appliance switch housing above and side be all filled with epoxy resin; therefore greatly improved the sealing effectiveness of carbon dioxide refrigerant with pressure controller; moisture is subject to the inside of just not entering switch case that stops of epoxy resin, makes pressure controller have water resistance.Because the two ends of reaction diaphragm are clamped between limiting plate and upper cover and by ferropexy circle, be fixedly connected with upper cover with limiting plate, by arranging of ferropexy circle, improved the explosion-proof performance of pressure controller.
