Description
Technical field
The present invention relates to a kind of cooling valve, a kind of Combined type back fuel tap is one of auxiliary equipment of screw refrigeration compressor unit, is mainly used in filtering, observing and regulate the lubricant oil separated from oil separator final stage oil content.The present invention is " national high-tech research development plan (863 Program) " subject achievements.
Background technique
At present, the supporting oil separator of screw refrigeration compressor unit is all high-efficiency oil separator, generally efficient filter core is all provided with in high-efficiency oil separator, after refrigerant gas enters efficient filter core, go out parts of lubricating oil through absorption, agglomeration separation, be deposited on oil content cylinder body bottom, this part must oil ratio must be led away, general is all by a filter of connecting, and looks oily mirror and a throttle valve, under differential pressure action, lubricant oil is got back to compressor air suction chamber for one.This method has following shortcoming: structure is scattered, and outward appearance is in disorder; Install inconvenient, generally by welding manner, these three parts are connected, solder joint is more, easily reveals, and is not easy to ensure turbidity test; Cost is higher, comprises cost of material and welding cost.
Summary of the invention
The object of this invention is to provide that a kind of structure is simple, easy installation and removal, take up room little, no-welding-spot, low cost of manufacture Combined type back fuel tap, overcomes the deficiencies in the prior art.
Combined type back fuel tap of the present invention, comprises valve body, and be provided with inlet union in one end of valve body, the other end is provided with outlet connection, is provided with filter member, fluid observation part, flow restriction control part between inlet attack and outlet connection successively;
Described filter member comprises the filtration core being arranged on body cavity, and there is strainer cover the termination of filtration core, filter gland with between valve body for being threaded and being provided with Sealing;
Described fluid observation part be connected with valve body screw thread look oily mirror, depending on being provided with sealing gasket between oily mirror and valve body;
Described flow restriction control part comprise be connected with valve body screw thread valve gap, be positioned at valve gap endoporus place and the valve rod be threaded with valve gap, seal ring is provided with between valve gap and valve body, valve rod inner termination is inlaid with seal ring, sealing ring and valve body inner via hole match, between valve gap and valve rod, be provided with filler, on filler, have the gland be threaded with valve gap.
Described valve gap is threaded and covers on the bonnet of valve rod external end head.
The material of described Sealing, sealing gasket, seal ring, seal ring is teflon; Described is sintered visor depending on oily mirror and is provided with mounting or dismounting groove; Described filtration core is inside-admission outside-exit type Stainless Steel Wire web frame.
Combined type back fuel tap of the present invention, filter, look oily mirror and throttle valve three component integrations on a scavenger valve, simple and compact for structure, easy installation and removal, takes up room little, does not have soldering point, greatly reduce cost.
Accompanying drawing explanation
Fig. 1 is the structural representation of the specific embodiment of the invention.
Embodiment
As shown in Figure 1: 2 is valve body, is connected with inlet union 1 at the threaded one end of valve body 2, the other end has been threaded outlet connection 10, is provided with filter member successively, fluid observes part, flow restriction control part between inlet attack 1 and outlet connection 10 in valve body 2.
Filter member comprises the filtration core 13 being arranged on valve body 2 inner chamber, and filtration core 13 is inside-admission outside-exit type Stainless Steel Wire web frame.There is strainer cover 11 termination of filtration core 13, for being threaded and being provided with Sealing 12 between filter gland 11 with valve body 2.
Fluid observation part be threaded with valve body 2 look oily mirror 4, depending on being provided with sealing gasket 3 between oily mirror 4 and valve body 2, be provided with mounting or dismounting groove depending on oily mirror 4 for sintered visor.
Flow restriction control part comprise be threaded with valve body 2 valve gap 6, be positioned at valve gap 6 endoporus place and the valve rod 9 be threaded with valve gap 6, be provided with seal ring 5 between valve gap 6 and valve body 2.Valve rod 9 inner termination is inlaid with seal ring, the annular relief of sealing ring and valve body 2 inner via hole periphery matches, rotation valve rod 9 can make seal ring press to the annular relief of valve body 2 inner via hole periphery, reaches the object of throttle down, and the size variation of unlatching can reconcile the many of throttling or few.Between valve gap 6 and valve rod 9, be provided with filler 8, on filler 8, have the gland be threaded with valve gap 6.
Valve gap 6 is threaded and covers on the bonnet 7 of valve rod 9 external end head.
The material of above-mentioned Sealing 12, sealing gasket 3, seal ring 5, seal ring is teflon.
During installation, inlet attack 1 connects with the secondary oil content return opening in refrigeration system, and outlet connection 10 connects with compressor air suction mouth.The lubricant oil separated by high-efficiency oil separator final stage oil content enters this scavenger valve by inlet attack 1 under differential pressure action, flow through after filter member is filtered and look oily Jing4Chu, by looking the mobility status of oily mirror 4 Observable lubricant oil, flow to compressor air suction mouth through flow restriction control part, by adjustment flow restriction control part regulate lubricating oil flow speed and by looking oily sem observation.
