Abstract
The invention discloses an electrically operated valve which is a refrigeration air conditioner accessory. The electrically operated valve comprises a valve body and a sleeve pipe, the valve body is installed on a locating piece, the sleeve pipe is fixed on the valve body, a barrel which extends into the sleeve pipe is arranged on the valve body, a cover is arranged at the lower end of the sleeve pipe, a mounting hole is formed in the cover, the outer diameter of the barrel is larger than that of the valve body, a step surface is formed on the outer side wall of a connecting position of the barrel and the valve body, the valve body penetrates the mounting hole, the step surface abuts against the upper surface of the cover, and the electrically operated valve is used for a refrigerant pipeline of a control system. By means of the electrically operated valve, when the inner diameter of a valve port of the electrically operated valve is increased within a certain range, a coil is merely required to be enlarged in order to increase starting force of the electrically operated valve.
Description
Technical field
The present invention relates to refrigeration air-conditioner accessory, particularly a kind of mortor operated valve.
Background technique
The structure of mortor operated valve at present, comprise the sleeve pipe on valve body and the fixed valve body being arranged on location piece, valve body is provided with the cylindrical shell stretching in sleeve pipe, and the external diameter of cylindrical shell is less than the external diameter of valve body, and sleeve pipe is set on valve body from the top down, in the time that the valve port internal diameter in valve body strengthens, in order to improve the tripping force of mortor operated valve, except increasing coil, also to increase valve body, so its cost also can correspondingly increase, and valve body increase after all test fixture also need change as fixture etc.
Summary of the invention
Problem to be solved by this invention is just to provide a kind of mortor operated valve, simple in structure, makes mortor operated valve in the time that valve port internal diameter strengthens within the specific limits, in order to improve the tripping force of mortor operated valve, only need to increase coil.
In order to achieve the above object, the present invention adopts following technological scheme: a kind of mortor operated valve, comprise the sleeve pipe on valve body and the fixed valve body being arranged on location piece, described valve body is provided with the cylindrical shell stretching in sleeve pipe, and the lower end of described sleeve pipe is provided with lid, and described lid is provided with mounting hole, the external diameter Φ A of described cylindrical shell is greater than the external diameter Φ B of valve body, on the outer side wall of described cylindrical shell and valve body joint, form step surface, described valve body is installed in mounting hole, and described step surface is against on the upper surface of lid.
Further, the lower surface of described lid is fitted on location piece, and described step surface and location piece clamp lid.Location while being convenient to assemble, strengthens the stability connecting.
Further, described sleeve pipe is sleeved on valve body from bottom to top, and described valve body, lid and location piece are welded and fixed.Technique is simple, fixing reliable.
Further, described cylindrical shell and valve body are structure as a whole.Be convenient to moulding, processing.
Further, described lid and sleeve pipe are structure as a whole.Be convenient to moulding, processing, guarantee sealing.
Adopt after technique scheme, tool of the present invention has the following advantages: in the time that the valve port internal diameter in valve body strengthens within the specific limits, in order to improve the tripping force of mortor operated valve, only need to increase coil, valve body structure is without variation, reduce cost of material, just can realize general for the test fixture for various valve port internal diameters as fixture simultaneously.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the invention will be further described:
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
Be an embodiment of the present invention as shown in Figures 1 to 3, a kind of mortor operated valve, comprise the sleeve pipe 2 on valve body 1 and the fixed valve body being arranged on location piece 3, described valve body is provided with the cylindrical shell 11 stretching in sleeve pipe, and the lower end of described sleeve pipe is provided with lid 4, and described lid is provided with mounting hole 41, the external diameter Φ A of described cylindrical shell is greater than the external diameter Φ B of valve body, on the outer side wall of described cylindrical shell and valve body joint, form step surface 12, described valve body is installed in mounting hole, and described step surface is against on the upper surface of lid.
In the present embodiment, the lower surface of described lid is fitted on location piece, and described step surface and location piece clamp lid.In the present embodiment, valve body is fixedly connected with location piece, lid is fixedly connected with location piece, step surface on valve body also can act on lid simultaneously, be equivalent to apply an auxiliary active force, contribute to the fixing of lid and location piece, thereby by interrelated to valve body, lid and location piece three, fixed effect is more reliable.And in prior art, lid and valve body clamping and positioning sheet, be actually lid and valve body to be separately fixed on location piece, between lid and valve body, there is no how many associated, the structure that after three is fixed together, intensity adopts not as the present embodiment.Described sleeve pipe is sleeved on valve body from bottom to top, installs also very conveniently, preferred, and described valve body, lid and location piece are welded and fixed.
Preferably described cylindrical shell and valve body are structure as a whole, this sampling technology is simple, and intensity is reliable, long service life.Can certainly adopt cylindrical shell and valve body are separated to making, then be fixed together by techniques such as welding.In like manner, preferably described lid and sleeve pipe are structure as a whole.
