Abstract
The utility model discloses a safety valve of a refrigerator pressure vessel, comprising a straight-way type valve body, a valve cap whose top is provided with air outlet holes, an air outlet connection pipe, the valve clack of an O-shaped sealing rubber ring on bottom plane, the valve seat of a plain valve port, an air inlet connection pipe and a filter net. The upper opening of the straight-way type valve body is connected with the valve cap, the upper end of the valve cap is connected with the air outlet connection pipe which penetrates the top center of the valve cap to connect a valve port open and close mechanism which is made of positioning bolts, and the air outlet connection pipe is corresponding to the position of the plain face valve port in the valve seat. The O-shaped sealing ring is arranged on the bottom plane of the valve clack in order to form a valve port closing surface, the bottom opening of the straight-way valve body is connected with the air inlet connection pipe, and the bottom opening end and the end surface of the air inlet connection pipe penetrates through the filter net. Owing to adopting a plain face valve port and the air inlet filter which has the valve port closing surface with good sealing performance and no leakage, the utility model with simple valve body structure and convenient processing has the advantages of environmental pollution prevention, safety and convenient use.
Description
Technical field
The utility model belongs to the build-up member that the refrigeration plant pressurized container is used, particularly a kind of safety valve that is used for the refrigerating machine pressurized container.
Background technique
At present, pressurized container in the refrigerating machine, be to be used for saving refrigeration ammonia, on pressurized container, safety valve must be housed, it is by three way valve, valve gap, system control valve port is opened, locking mechanism, the valve port sealing surface that flap and valve seat constitute is formed, the mouth of pipe on the straight-through side in three way valve is the mouth of pipe of giving vent to anger, system control valve port switching mechanism is by last, following positioning disk, holding down bolt, locking ball, spring is formed, the valve port sealing surface embeds the flap of ptfe plastic by the bottom surface and is made up of the valve seat of protruding valve port, make ptfe plastic bottom plane on the flap and the protruding valve port in the valve seat, just constituted the sealing surface of safety valve valve port.When ammonia enters the refrigerating machine of work by inlet end, during overpressure, have the ammonia of pressure to back down flap, ammonia flows into the air along the outlet side of the valve port of opening by air outlet hole threeway from valve body of valve seat both sides, refrigerating machine is reduced pressure, play safety effect.In the course of time, the protruding valve port of stainless steel will make to produce on the ptfe plastic bottom surface on the flap and be pressed into groove mark, simultaneously, owing to be mingled with foreign particles in the ammonia, will be trapped on the valve port sealing surface, cause valve port sealing surface poor sealing and produce seepage, not only wasted ammonia, but also befouling environment and dangerous; Simultaneously, three interface tubes of valve body band, its shape and structure become complicated and are not easy to processing.
Summary of the invention
The utility model purpose is the defective that exists in above-mentioned technology and deficiency and provide a kind of valve body structure that both made simple, is convenient to processing, makes the safety valve of the refrigerating machine pressurized container of valve port sealing surface good seal again.
The purpose of this utility model realizes with following technological scheme: the safety valve of refrigerating machine pressurized container, comprise valve body, valve gap, system control valve port open and close mechanism, flap, valve seat, it is characterized in that: mainly by the straight-through type valve body, the valve gap of the uniform air outlet of tops, give vent to anger connecting tube, bottom plane has the flap of " O " type O-ring seal, and the valve seat of plane valve port, inlet pipe connection, filter screen are formed.Valve gap in the uniform air outlet, connecting cover suitable for reading top of straight-through type valve body, the valve gap upper end connects the connecting tube of giving vent to anger, with the valve port position, plane in the valve seat is corresponding, dress " O " type O-ring seal on the flap bottom surface, constitute the valve port sealing surface with the plane valve port, straight-through type valve body end opening is adorned filter screen with the inlet pipe connection that is threaded between stretched formula valve body lower end and inlet pipe connection end.The straight-through type valve body valve gap with the uniform air outlet hole of its tops that is threaded suitable for reading that communicates at upper and lower opening, the valve gap top center connects the open and close mechanism of the system control valve port of upper and lower positioning disk, spring, locking ball composition with the holding down bolt that is threaded by the circular cone of holding down bolt; Valve port in the valve seat changes the protruding valve port in the prior art into the plane valve port, and corresponding with valve port position, plane, and " O " type O-ring seal is housed on the flap base, and described " O " type O-ring seal adopts rubber material heat-resisting, sour, antifriction to make.Make valve port form the combined valve port sealing surface of soft or hard material, its sealing is good, in order to prevent in the gas or valve body is left over entering of foreign matter with inlet pipe connection, is provided with filter screen in suction tude in addition, makes the gas that enters obtain filtration.In sum, thus realize the purpose of this utility model.
Compared with prior art, the utility model not only had valve body simple in structure, be convenient to process but also owing to adopt the plane valve port and make the valve port sealing surface have sealing to the filtration of air inlet good, prevent seepage, and free from environmental pollution, and safe in utilization, easy to operate.
Description of drawings: the utility model has a width of cloth accompanying drawing.
Wherein: accompanying drawing 1 is the main sectional structure schematic representation of the utility model specific embodiment.
Among the figure 1, the connecting tube 2 of giving vent to anger, holding down bolt 3, valve gap 4, air outlet hole 5, straight-through type valve body 6, go up positioning disk 7, flap 8, positioning disk 9, valve seat 10, locking ball 11, " O " type O-ring seal 12, inlet pipe connection 13, filter screen 14, spring down
Embodiment
Shown in Figure 1 is specific embodiment of the utility model, by steam outlet pipe 1, holding down bolt 2, valve gap 3, upper and lower positioning disk 6,8, spring 14, locking ball 10, straight-through type valve body 5, flap 7, valve seat 9, filter screen 13, inlet pipe connection 12, form.Be furnished with air outlet hole 4, its tops center the valve port open and close mechanism that forms by upper and lower positioning disk 6,8, spring 14, locking ball 10 the suitable for reading of the straight-through type valve body 5 of steel with the steel valve gap 3 that is threaded, valve gap 3 tops with the holding down bolt 2 system controls that are threaded, the O-ring seal 11 of heat-resisting, sour, the rub resistance of dress " O " type on the bottom plane of flap 7, constitute the valve port sealing surface with the plane valve port on the base 9, with the inlet pipe connection 12 that is threaded, between straight-through type valve body 5 lower ends and inlet pipe connection end, be equipped with filter screen 13 at straight-through type valve body 5 end openings.
