Abstract
A valve body component of a four-way valve belongs to parts of a heat-pump type air conditioner. The prior art has the disadvantages of material waste and heat transfer loss in the system. The utility model includes a tubular valve body, a valve seat fixed on the inner wall of the valve body, a D adapter directly connected with the valve body, and a C adapter, an E adapter and an S adapter connected with the valve seat through the valve body in parallel. The utility model is characterized in that a platform protruding to the inner cavity of the valve body is arranged at the middle position of the pipe wall of the valve body; and the bottom of the valve seat is flat and is fixed on the platform through the flat surface. Accordingly, the size between the top surface and the bottom surface of the valve seat can be reduced to save material. Simultaneously, the heat transfer areas among the C, the E and the S adapters can be reduced, thereby reducing the heat transfer loss in the system.
Description
Technical field
The utility model relates to the electromagnetism four-way change-over valve of heat pump-type idle call, this electromagnetism four-way change-over valve is used for the flow direction that heat pump type air conditioner changes refrigeration working medium, realize the function that heat pump type air conditioner system refrigeration in summer, winter heat, it also can be used for the defrost of heat pump type air conditioner system simultaneously.
Background technique
The valve body parts of the electromagnetism four-way change-over valve of existing structure is made up of parts such as D adapter 1, valve body 2, valve seat 3, C adapter 4, E adapter 5, S adapters 6 shown in figure one.Valve body wherein is straight-through shape tubular structure, because valve seat will be fixed on the inwall of pipe shape valve body, pretend the bottom surface 3.1 that is connected with valve interior wall for valve seat and be curved surface (cylndrical surface), the cross section of Xing Chenging is " D " shape thus, C, E, three adapters of S are passed valve body hole 2.1 and are inserted in the valve seat orifice 3.2 again, fuse by welding and valve seat then.
Because the valve seat cross section of said structure is " D " shape, so the degree of depth of its valve seat orifice 3.2 hole walls is not of uniform size because of passing through mutually with the curved surface of valve seat, therefore, on product for guaranteeing and C, E, the welding section 4.1 of three adapters of S, 5.1,6.1 minimum length (i.e. three adapters of this minimum length and the minimum superposition section of locating of the valve seat orifice hole wall degree of depth), the entire depth of valve seat orifice just should be big (i.e. the superposition section of three adapters and valve seat orifice hole wall degree of depth biggest place is greater than aforesaid minimum length) then, therefore just need to guarantee that the distance between valve seat end face 3.3 and its bottom surface 3.1 is enough big, obvious, this must need to drop into enough materials, has waste; And enough big valve seat end face and the distance between its bottom surface make the heat transfer area between C, E, three adapters of S also bigger, thereby the heat transfer loss who is caused in system is also just more.
The model utility content
The technical assignment of the technical problems to be solved in the utility model and proposition is to overcome the waste material of prior art existence and the defective that there is the heat transfer loss in system, and a kind of four-way valve body parts are provided.For this reason, the utility model is by the following technical solutions:
The four-way valve body parts, comprise tubular valve body and the valve seat that is fixed on valve interior wall, a D takes over and directly is connected on the valve body, C arranged side by side takes over, E takes over, the S adapter is passed valve body and is connected on the valve seat, the position, tube wall stage casing that it is characterized in that described valve body is to the outstanding platform of body cavity, and the bottom surface of described valve seat is the plane and is fixed on this platform by this plane.
As the further of technique scheme improved and replenish, when concrete enforcement scheme of the present utility model, can adopt following additional technical characteristics:
Described four-way valve body parts is characterized in that described C arranged side by side takes over, E takes over, the S adapter is fixed by welded seal with valve body, valve seat.
Described four-way valve body parts is characterized in that two sides of described valve seat are curved surface.
Described four-way valve body parts is characterized in that two sides of described valve seat are the plane vertical with the end face of valve seat.
Described four-way valve body parts, two sides that it is characterized in that described valve seat are the plane that intersects obtuse angle or acute angle with the end face of valve seat.
The beneficial effects of the utility model are: give prominence to a platform by the position, tube wall stage casing at valve body to body cavity, the plane of valve seat by its bottom is fixed on this platform, can reduce the size between valve seat end face and the bottom surface thus, economical with materials; The processing of valve seat is also easier in addition, and simultaneously, because size is reduced, the heat transfer area between C, E, three adapters of S is also reduced, thereby the heat transfer loss who is caused in system is also just less.
Description of drawings
Fig. 1 is the structure sectional view of the four-way valve body parts of prior art.
Fig. 2 is the left view of Fig. 1.
Fig. 3 is the structure sectional view of one of them embodiment's of the present utility model four-way valve body parts.
Fig. 4 is the left view of Fig. 3.
Among the figure: 1-D takes over, the 2-valve body, and the 2.1-valve body hole, the 2.2-platform, the 3-valve seat, 3.1-valve seat bottom surface, the 3.2-valve seat orifice, 3.3-valve seat end face, 3.4-valve seat side, 4-C takes over, and 5-E takes over, and 6-S takes over, the 4.1/5.1/6.1-welding section.
Embodiment
By embodiment the utility model is done specific description below in conjunction with Figure of description.
Embodiment one
Shown in Fig. 3,4, the formation of these four-way valve body parts is with identical shown in Fig. 1,2, comprise that 3, one D of tubular valve body 2 and the valve seat that is fixed on valve body 2 inwalls take over 1 and directly are connected on the valve body 2, C adapter 4 arranged side by side, E adapter 5, S adapter 6 are passed valve body 2 and are connected on the valve seat 3; Its difference is:
The tube wall stage casing of valve body 2 and valve seat are joined the weldering position and are given prominence to a platform 2.2 by stretch process to body cavity; The plane is processed in the bottom surface 3.1 of valve seat 3, by this plane valve seat 3 is weldingly fixed on the platform 2.2; And two sides 3.4 of valve seat 3 are the plane vertical with the end face 3.3 of valve seat, and the valve seat cross section of Xing Chenging is rectangle (this structure is convenient to processing) thus.Based on said structure, the degree of depth unanimity of valve seat orifice 3.2 hole walls, guaranteeing and C, E, the welding section 4.1 of three adapters of S, 5.1,6.1 minimum length the time, the end face 3.3 of valve seat 3 and the distance between the bottom surface 3.1 are shortened greatly, Fig. 3,4 show, the C that connects same specification on the valve body 2 of same specification, E, three adapters of S, the specification of valve seat 3 (its thickness especially, be the size between end face and the bottom surface) dwindle greatly, so promptly saved material, make C, E, heat transfer area between S takes over is also just less, thereby the heat transfer loss who is caused in system is also just less.
Other embodiment
Be reference with embodiment one, when realizing product, two sides of valve seat can also intersect the plane of obtuse angle or acute angle for curved surface or with the end face of valve seat, do not repeat them here.
