Abstract

The utility model discloses an electromagnetic four-way reversing valve. A main valve body is provided with a pilot valve and a coil. A filtering net is arranged in a tube opening of a D tube of the main valve body. The edge of the filtering net is wrapped by a brass net rack for punching. The filtering net used in the electromagnetic four-way reversing valve can filter foreign matter in the pilot valve and foreign matter entering the main valve. Therefore, inner leakage performance of the main valve is improved, the main valve can be observed and checked directly through naked eyes, and the phenomenon of neglected assembly of the filtering net is avoided.

Description

A kind of electromagnetism four-way change-over valve
Technical field:
The utility model relates to a kind of electromagnetism four-way change-over valve, is specially adapted to install and use on the air-conditioning.
Background technique:
The assembling fittings of existing electromagnetism four-way change-over valve is by being equipped with pilot valve 2 on the main valve body 1 and coil 3 constitutes, the formation of described pilot valve assembly 2 is by capillary tube 7-d, 7-e, 7-c and 7-s form, with pilot valve body 4 and pilot valve seat 5 welding, stop up capillary tube and cause and to commutate for avoiding foreign matter in the refrigeration system to enter pilot valve, or the sealing surface that blocks between pilot valve slide block 8 and the pilot valve seat 5 causes interior leakage, in order to solve the problem of above-mentioned existence, be that 7-d capillary tube is carried out enlarging processing at present, and a filter screen 6 is put in the inside after enlarging, the shortcoming that this scheme exists is: because this filter screen is very tiny, operation inconvenience, if put filter screen because the operator neglects to leak, do not destroy pilot valve after the welding, can't find, be subjected to the influence of 7-d capillary size in addition, the diameter of filter screen has only 4mm, the burr of filter cloth edge can't be encased, will exist the burr burr to come off, the filter screen that causes pilot valve to be placed does not only play the effect of filtering foreign matter, also very likely influences the performance of electromagnetism four-way change-over valve because of coming off of the foreign matter of filter screen own.
Summary of the invention:
Task of the present utility model is to propose a kind of directly observation and inspection filter screen whether a kind of electromagnetism four-way change-over valve that the filter cloth edge burr after the installation can not come off is installed.
Task of the present utility model is finished like this, a kind of electromagnetism four-way change-over valve, it comprises and is equipped with pilot valve and coil on the main valve body, it is characterized in that: at the built-in filter screen that is placed with of the mouth of pipe of main valve body D pipe, described filter screen edge is with the punching press of brass rack parcel.
The utlity model has following effect: the foreign matter that the filter screen that the utility model uses not only enters pilot valve can filter, and the foreign matter that enters main valve body also can filter, thereby improved the interior leakage performance of main valve body, and can stop the generation of neglected loading filter screen phenomenon directly by the perusal inspection.
Description of drawings:
Fig. 1 is the prior art structural representation; Fig. 2 is the structure cut-away view of prior art guide valve body; Fig. 3 is structural representation of the present utility model; Fig. 4 is the structural representation of filter screen.
Drawing explanation: 1, main valve body, 2, pilot valve, 3, coil, 4, pilot valve body, 5, pilot valve seat, 6, filter screen, 7-d capillary tube, 7-e capillary tube, 7-c capillary tube, 7-s capillary tube, 8, pilot valve slide block, 9, main valve body D pipe, 10, filter screen, 11, the brass rack.
Embodiment:
Describe embodiment in detail in conjunction with above accompanying drawing, the technical solution of the utility model unlike the prior art be, in the mouth of pipe inner chamber of main valve body D pipe 9, put filter screen 10 is arranged, the edge of described filter screen 10 is with the 11 parcel punching presses of brass frame together, filter screen behind the employing parcel is put into the mouth of pipe of main valve body D pipe, can reach the foreign matter that to enter pilot valve equally and filter, avoid coming off of prior art filter screen burr burr.
