Description

Main valve body using method of compressor, evaporator and condenser

Technical Field

The invention relates to a compressor, an evaporator and a use method of a main valve body of a condenser.

Background

The refrigerating system of air conditioner is mainly composed of compressor, evaporator, condenser and various regulating valve bodies. Taking the electronic expansion valve as an example, the stepping motor direct-acting electronic expansion valve is a key part for adjusting the flow of the air conditioning system. The main valve body is equivalent to the rotor part of the stepping motor, the coil is equivalent to the stator part of the stepping motor, and a pulse driving signal is applied to a coil winding to generate a regular magnetic field on a pole claw of a coil magnetizer to drive the rotor in the main valve body to rotate, so that the flow at the valve port of the main valve body is adjusted, and the flow in the system is controlled.

However, the expansion valve may shake during use, and the connection rod between the driving coil and the main valve body may loosen and fall off after a long period of use. In order to avoid the problem, many expansion valve solutions are all to want the method to strengthen the connection between drive coil and the main valve body, the rivet mode is used without worry, for example, CN 201110172039's patent, but at first can not solve at all that long-time trembling can bring the connecting rod between drive coil and the main valve body and usually can drop like this, and two big problems have also been newly increased, 1, unable convenient disassembling, it is the necessary function of many solenoid valves to dismantle between drive coil and the main valve body, at first utilize the assembly, secondly, bad part can be renewed soon and has been changed, avoid wholly taking the maintenance. 2. The vibration of the coil caused by the shaking of the main valve body still cannot be reduced, and the main valve body still can be loosened and fall off after a long time.

Detailed Description

The invention will be described in further detail with reference to the following figures and specific examples, without limiting the scope of the invention.

As shown in fig. 1 to 6, the main valve body using method of a compressor, an evaporator and a condenser in this embodiment includes a main valve body fixing portion b1, a pipeline b4, an induction portion, and a cake ring b2 sleeved on the main valve body fixing portion, where the cake ring b2 includes a hole for sleeving the main valve body fixing portion, and four arc pits b5 are provided on the periphery of the cake ring b2 facing the center; four arc shaped hollows b5 are arranged at equal intervals.

Certainly, the main valve body is a main valve body which can be conveniently detached, and in order to match the structure, a coil part matched with the main valve body is provided, the coil part comprises a cake-shaped cloud plate a1, a plurality of clamping claws a3 are equidistantly arranged on the cloud plate a1, a driving coil a2 is clamped on the top surface of the cloud plate a1 through the clamping claws a3, the center of the cloud plate a1 is provided with a central hole a9 for enabling the main valve body to pass through the cloud plate a1 to reach the driving coil a2, the bottom surface of the cloud plate a1 is provided with four symmetrical top valves which are symmetrically and symmetrically arranged in the center, each top valve comprises an accommodating cavity a4, one side of the accommodating cavity a4, which faces the center of the cloud plate a1, the opening extends to the radial direction of the accommodating cavity a4 to form a5, the bottom surface of the accommodating cavity a1 further comprises a8 which is cylindrical and is positioned at the opening of the accommodating cavity a4, one end of the bullet a8 is hemispherical, and the other end of the bullet is connected with the bottom of the accommodating cavity 4 through a compression spring; a clamping arm a6 corresponding to the retaining wall a5 is protruded from the side surface of the bullet a8 close to one end of the compression spring;

when the expansion valve is used, the main valve body part is plugged into the central hole a9 at the bottom of the cloud plate a1, and one end of the cylindrical bullet head a8 is placed in the arc-shaped pit b5, so that the assembly is completed. The main valve body is held in this fixed position due to the snap action of the bullet a 8. When shaking, because of the compression spring, the shaking can be effectively filtered, and in addition, the catching arm a6 and the retaining wall a5 of the bullet a8 play a role in preventing the bullet a8 from completely escaping out of the accommodating chamber a 4.

In this embodiment, the number of the claws a3 on the cloud plate a1 is three so as not to shield the wire connecting portion a10 of the driving coil a 2. The most types of coils can be replaced by replacing the wiring part a10 with a position.

In this embodiment, the arc shaped dimples b5 include spherical concavities and cylindrical tunnels. This increases the depth of the arc-shaped pit b5, and effectively prevents the bullet a8 from running out.

In this embodiment, a first magnet a7 is embedded below the cloud plate a1 and at the periphery of the central hole a 9. Wherein, the top surface of the cake ring b2 is embedded with a second magnet b3 above the arc-shaped pit b 5. The two magnets are opposite and attracted, so that the holding force between the cake ring b2 and the cloud plate a1 of the main valve body is effectively increased, and the main valve body is further prevented from falling off.

Through the cooperation of cloud board a1 and cake circle b2, realize two main functions, 1. extend life, because the effect of compression spring for main valve body has certain shock attenuation effect in the vibrations process, makes the vibrations influence between the main valve body and the coil reduce greatly, great increase the life of expansion valve. 2. The main valve body can be conveniently disassembled, and the main valve body can be conveniently disassembled from the cloud board a1 only by one toothpick. Before the applicant designs the product, through multiple researches, the radial vibration times of the main valve body are far larger than the axial vibration times and amplitude when the expansion valve vibrates. It follows, therefore, that the frequency and amplitude of the transverse oscillations are large, which results in a loose connection between the main valve body and the coil until the connection is broken off. Solving this problem therefore requires avoiding lateral vibrations to be the main direction of the design.

The above description is only a preferred embodiment of the present invention, and all equivalent changes or modifications of the structure, characteristics and principles described in the present patent application are included in the protection scope of the present patent application.
