Abstract
The invention discloses a kind of motor-driven valve, for refrigeration air-conditioner accessory, so that motor-driven valve is when valve port internal diameter is increased within the specific limits, in order to improve the startup power of motor-driven valve, only need to increase coil, including the sleeve pipe on the valve body and fixed valve body on spacer, the valve body is provided with the cylinder stretched into sleeve pipe, the lower end of described sleeve pipe is provided with lid, the lid is provided with mounting hole, the external diameter of the cylinder is more than the external diameter of valve body, the cylinder on the lateral wall of valve body junction with forming step surface, the valve body is installed in mounting hole, the step surface is against on the upper surface of lid, in pipeline for control system refrigerant.
Description
Technical field
The present invention relates to refrigeration air-conditioner accessory, particularly a kind of motor-driven valve.
Background technology
Set on the structure of current motor-driven valve, including the sleeve pipe on the valve body and fixed valve body on spacer, valve body
There is the cylinder stretched into sleeve pipe, the external diameter of cylinder is smaller than the external diameter of valve body, and sleeve pipe is set on valve body from the top down, when in valve body
When valve port internal diameter is increased, in order to improve the startup power of motor-driven valve, in addition to increasing coil, also to increase valve body, so its cost
Also can accordingly it increase, and all test fixture such as fixture etc. is also required to change after valve body increase.
The content of the invention
Problem to be solved by this invention is just to provide a kind of motor-driven valve, simple in construction so that motor-driven valve is in valve port internal diameter
When increasing within the specific limits, in order to improve the startup power of motor-driven valve, it is only necessary to increase coil.
In order to achieve the above object, the present invention is adopted the following technical scheme that：A kind of motor-driven valve, including on spacer
Valve body and fixed valve body on sleeve pipe, the valve body is provided with the cylinder that stretches into sleeve pipe, and the lower end of described sleeve pipe is provided with lid
Body, the lid is provided with mounting hole, and the external diameter Φ A of the cylinder are more than the external diameter Φ B of valve body, and the cylinder is connected with valve body
Step surface is formed on the lateral wall at place, the valve body is installed in mounting hole, and the step surface is against on the upper surface of lid.
Further, the lower surface of the lid is fitted on spacer, and the step surface and spacer clamp lid.Just
Positioned when assembling, strengthen the stability of connection.
Further, described sleeve pipe is sleeved on valve body from bottom to top, and the valve body, lid and spacer are welded and fixed.
Technique is simple, fixed reliable.
Further, the cylinder is structure as a whole with valve body.It is easy to be molded, processes.
Further, the lid is structure as a whole with sleeve pipe.It is easy to be molded, processes, it is ensured that sealing.
After adopting the above technical scheme, the invention has the advantages that：When the valve port internal diameter in valve body within the specific limits
During increasing, in order to improve the startup power of motor-driven valve, it is only necessary to increase coil, valve body structure without change, reduction material into
This, while can be achieved with for the test fixture such as fixture for various valve port internal diameters general.
Brief description of the drawings
The invention will be further described below in conjunction with the accompanying drawings：
Fig. 1 is the structural representation of an embodiment of the present invention；
Fig. 2 is the structural representation of valve body；
Fig. 3 is the structural representation of sleeve pipe and lid.
Embodiment
It is an embodiment of the present invention, a kind of motor-driven valve, including the valve body 1 on spacer 3 as shown in Figures 1 to 3
With the sleeve pipe 2 on fixed valve body, the valve body is provided with the cylinder 11 stretched into sleeve pipe, and the lower end of described sleeve pipe is provided with lid 4,
The lid is provided with mounting hole 41, and the external diameter Φ A of the cylinder are more than the external diameter Φ B of valve body, and the cylinder is connected with valve body
Step surface 12 is formed on the lateral wall at place, the valve body is installed in mounting hole, and the step surface is against on the upper surface of lid.
In the present embodiment, the lower surface of the lid is fitted on spacer, and the step surface and spacer clamp lid.
Valve body is fixedly connected with spacer in the present embodiment, lid is fixedly connected with spacer, while the step surface on valve body can also be made
With on lid, equivalent to the active force for applying an auxiliary, contribute to the fixation of lid and spacer, so as to by valve body, cover
Body and spacer three are interrelated, and fixed effect is relatively reliable.And in the prior art, lid and valve body clamping and positioning
Piece, actually lid and valve body are separately fixed on spacer, and between lid and valve body and without associating, three is fixed on
Intensity is not so good as the structure that the present embodiment is used after together.Described sleeve pipe is sleeved on valve body from bottom to top, is installed also very square
Just, it is preferred that the valve body, lid and spacer are welded and fixed.
It is preferred that the cylinder and valve body are structure as a whole, this sampling technology is simple, and intensity is reliable, and service life is long.Certainly
It can also use and be fabricated separately cylinder with valve body, then be fixed together by techniques such as welding.Similarly, preferably by the lid
It is structure as a whole with sleeve pipe.
