Description
Technical field
The utility model relates to a kind of one-way valve that improves structure, relates in particular to the one-way valve that is used in the chiller plant pipeline.
Background technique
At present, the one-way valve that uses on the chiller plant (referring to as Fig. 1 and Fig. 2), all have in red copper valve pipe 1 inside on the structure one with the seal valve seat 11 spool fitted seal, that form through machining with the brass section bar.The effect of seal valve seat 11 is, when one-way valve need be closed, spool have one can stop bit, the mating parts of sealing, and when one-way valve was in opening state, seal valve seat just cut little ice.The existence of this seal valve seat has increased the cost of product.
Therefore, remain in structure and carry out improved space, both guarantee effective sealing, can reduce the one-way valve of number of parts, reduction cost of goods manufactured again to provide to one-way valve.
The model utility content
The purpose of this utility model provides a kind of one-way valve that improves structure, to simplify its structure and to reduce production costs.The inwall that the one-way valve that the utility model proposes comprises the valve pipe, be located at the spool in the valve pipe and be fixedly connected on the valve pipe movably is with the block piece of restriction spool in valve inner axial tube mobile position.This valve pipe comprises the section of dwindling, and this section of dwindling forms a sealed mouth in described valve pipe, and this spool is between sealed mouth and block piece.
In a kind of embodiment, the part that sealed mouth is used for cooperating with spool is a conical surface.As further preferred, spool can cooperate with described sealed mouth with a plane.This plane is the table top of a size less than the step of spool body, and this makes that described spool and contacting of described sealed mouth are line contacts roughly.
In another embodiment, spool cooperates with described sealed mouth by the conical surface of being located at the one end.
In one embodiment, between described spool and valve pipe, be provided with guide pin bushing, described spool carried out axial limiting by the combination of described guide pin bushing and described block piece.In this case, described block piece is preferably a backing pin.
In another embodiment, described block piece is a baffle ring.
In another embodiment, described block piece is the muscle that contracts.
The valve pipe adopts red copper material (or aluminium, steel such as stainless steel) processing, guide pin bushing, baffle ring, can use cheap material processing such as steel such as stainless steel, aluminium, zinc alloy material or resin instead, substitute original copper product processing, thereby reduce cost of material, simplified manufacturing technique.
One-way valve of the present utility model especially is suitable for use in the air-conditioning equipment.Compared with prior art, the inside latus rectum of one-way valve, flow keep consistent with existing product, avoid using the air-conditioning equipment performance of this product influenced, but have reduced the part of present one-way valve, and material is replaced and reduced cost of production simultaneously.

Embodiment
Fig. 3 shows the structural drawing according to an embodiment's of the utility model one-way valve.One-way valve 30 comprises valve pipe 1, spool 2, guide pin bushing 3 and backing pin 4.Valve pipe 1 comprises a section of dwindling 8, and the diameter of this section of dwindling 8 designs according to the flow needs of stream.Forming a sealed mouth 7 by this section of dwindling 8 in the valve pipe, sealing mouth 7 or process increase finishing such as impact extrusion, shaping, make it have the shape and the surface finishment of rule more.Spool 2 is provided with near the section of dwindling 8, and it is by the sealing that realizes pipeline that cooperates of the conical surface 9 with the sealed mouth 7 of spool one end.In the present embodiment, spool 2 is arranged in the guide pin bushing 3 and can moves in guide pin bushing 3, is provided with backing pin 4 at the other end with respect to the section of dwindling 8 of guide pin bushing, is used for playing restriction spool 2 and continues the effect of moving to far-end when spool 2 leaves sealed mouth 7.Guide pin bushing 3 can curl with steel plate and be processed to form, and also can cut off and be processed to form with steel pipe, aluminum pipe; Also can be processed to form with resin material injection moulding, mold pressing etc.; Also can form with zinc alloy material die casting.
Fig. 4 illustrates the structural drawing according to another embodiment's of the utility model one-way valve 40.The difference of itself and device shown in Figure 3 is, in the present embodiment, as spool 2 limit stoper be baffle ring 5, rather than backing pin 4.Baffle ring 5 can cut off and be processed to form with steel pipe, aluminum pipe, also can be processed to form with resin material injection moulding, mold pressing etc.; Also can form with zinc alloy material die casting.In addition, outside the spool 2 guide pin bushing is set no longer, spool directly moves around along the valve inner tube wall.
Fig. 5 illustrates the structural drawing according to another embodiment's of the utility model one-way valve 50.The difference of itself and device shown in Figure 3 is, in the present embodiment, as spool 2 limit stoper be the muscle 6 that contracts, rather than backing pin 4.In addition, outside the spool 2 guide pin bushing is set no longer, spool directly moves around along the valve inner tube wall.
In the utility model, the sectional shape of the non-conical surface part of spool can be diversified.It can be triangle, quadrilateral or other polygonal shapes.It also can be almost circular.For back one situation, spool has some grooves in non-conical surface part near outer circumferential face, so that the stream of fluid to be provided.
Fig. 6 illustrates the structural drawing according to another embodiment's of the utility model one-way valve 60, and the difference of itself and previous embodiment is that as shown in the figure, the part that sealed mouth 7 is used for cooperating with spool 2 has a conical surface 71.2 of spools comprise body 21 and are located at the cylindrical step 22 in body one end neutral position that spool matches with the conical surface 71 of sealed mouth by step 22, realizes the break-make of one-way valve.Point out that at this conical in shape of sealing mouth is optional, it also can have flat end face.Realize sealing as long as can match with spool.
Preferably, the sealing mouth makes it have the shape and the surface finishment of rule more through increasing finishing such as impact extrusion, shaping, can be fully and the spool fitted seal.
In the utility model, valve pipe 1 can adopt copper product (or aluminium, steel such as stainless steel or carbon steel) manufacturing, and carry out necking down processing therebetween, and make it form the section of dwindling with sealed mouth 78 that matches with the seal spool conical surface, replace original sealing seat (parts 2 among Fig. 1).Inner other part of valve pipe can use cheap materials such as steel (as stainless steel or carbon steel and other steel), aluminium, resin to make, to reduce cost.Compared with prior art, its inner latus rectum, flow keep consistent with existing product, avoid using the air-conditioning equipment performance of this product influenced, have reduced the part of present one-way valve simultaneously, have reduced manufacture cost.
The utility model is described by above-mentioned related embodiment, yet the foregoing description is only for implementing example of the present utility model.Must be pointed out that the embodiment who has disclosed is not used for limiting scope of the present utility model.On the contrary, be contained in the modification of the spirit of claim and scope and be equal to be provided with and all be included in the claims restricted portion.
