Abstract
The utility model discloses a pilot valve body, be provided with impress the pilot valve seat and the sheathed tube tube hole of packing into on pilot valve body's the body, the tube hole of pilot valve seat impressed be set up pilot valve body's arc surface envelope to face department, the sheathed tube tube hole of impressing is the horizontal position who sets up at pilot valve body, beat the hole of 3 assembly capillaries in the pilot valve seat, be equipped with EC capillary and S capillary in the hole respectively, press from both sides in the middle of the EC capillary and be equipped with S capillary welding equipment, beat the tube hole of assembly D capillary on pilot valve body's the face, the arc surface envelope is personally submitted to this of D capillary tube hole, the arc surface envelope embolias this terminal surface of sleeve pipe and is the plane. The utility model discloses the location of production process can be be arranged in, the processing degree of difficulty reduced, at the in -process non -deformable that brazes to reduce the outside leakage rate of valve body.
Description
Technical field:
The utility model relates to a kind of guide valve blocks, is specially adapted to valve field uses.
Background technique:
Valve body utilizes a movable part carry out open and close or partly block one or more openings or passage, makes liquid stream, air stream or other air-flows or a large amount of bulk material can flow out, block or adjusted a kind of device.Four-way valve belongs to the one of valve body, pilot valve is applied to the important component of of four-way valve, it has vital impact to the noise of product, interior leakage, and the shortcoming of current pilot valve is: easily reveal when guide valve blocks welds with stainless steel sleeve pipe, in production process, reject ratio is high.
Summary of the invention:
Task of the present utility model is to provide a kind of reduction difficulty of processing, not yielding in brazing process, reduces a kind of guide valve blocks of the External leakage of valve body.
Task of the present utility model completes like this, a kind of guide valve blocks, it is characterized in that: the pore body of guide valve blocks being provided with press-in guide valve seat and loading sleeve pipe, press-in guide valve seat pore be the arc surface envelope being arranged on guide valve blocks to face place, the pore of press-in sleeve pipe is the horizontal position being arranged on guide valve blocks, the hole of 3 assembling capillary tubies is equipped with in guide valve seat, EC capillary tube and S capillary tube is respectively fitted with in hole, the therebetween of EC capillary tube is equipped with S capillary tube welding assembly, a face of guide valve blocks is equipped with the pore of assembling D capillary tube, this one side of described D capillary tube pore is in arc surface envelope, it is plane that described arc surface envelope is inserted in this end face of sleeve pipe.The body of guide valve blocks has 2 pores, described sleeve pipe and guide valve seat and pore are interference fit.Be equipped with core iron in described sleeve pipe, Returnning spring is equipped with in the front end of core iron, and the press-in end of sleeve pipe is provided with chamfering and guide valve blocks interference fit, and the other end of sleeve pipe is welded by argon arc welding between attractor.
The utility model has following effect: may be used for the location in production process, reduces difficulty of processing, not yielding in brazing process, thus reduces the External leakage rate of valve body.
Accompanying drawing illustrates:
Fig. 1 is structural representation of the present utility model; Fig. 2 is the external structure schematic diagram of guide valve blocks; Fig. 3 is the side view of Fig. 2.
Drawing illustrates: 1, guide valve blocks, 2, guide valve seat, 3, EC capillary tube, 4, S capillary tube, 5, sleeve pipe, 6, attractor, 7, D capillary tube, 8, core iron, 9, Returnning spring, 10, arc surface envelope.
Embodiment:
The utility model guide valve blocks 1 and fixing frame are fixed, the body of guide valve blocks 1 is provided with the pore of press-in guide valve seat 2 and loading sleeve pipe 5, furtherly: the body of guide valve blocks has 2 pores, described sleeve pipe 5 and guide valve seat 2 are interference fit with pore, object improves join strength and is conducive to the location before welding, not easily rock, furtherly: press-in guide valve seat pore be the arc surface envelope 10 being arranged on guide valve blocks to face place, the pore of press-in sleeve pipe is the horizontal position being arranged on guide valve blocks, guide valve seat 2 li is equipped with the hole of 3 assembling capillary tubies, EC capillary tube 3 is respectively fitted with in hole, the therebetween of EC capillary tube 3 is equipped with S capillary tube 4 welding assembly, described sleeve pipe 5 li is equipped with core iron 8, Returnning spring 9 is equipped with in the front end of core iron 8, the press-in end of sleeve pipe is provided with chamfering and guide valve blocks interference fit, the other end of sleeve pipe is welded by argon arc welding with between attractor 6.
A face of guide valve blocks is equipped with the pore of assembling D capillary tube 7, this one side of described D capillary tube pore is in arc surface envelope 10, object is not yielding in welding process, be heated evenly, thus reduce the External leakage of valve body, it is plane that described arc surface envelope is inserted in this end face of sleeve pipe, is convenient to the location in production process.
