specific Embodiment 1

[0023] Reference figure 1 This embodiment 1 includes a valve body 1 and a valve core 2. The valve body 1 and the valve core 2 are formed by a copper tube stamping and forming an integral structure. The two ends of the formed throttle valve are the valve body 1 and the valve core 2 is formed in the middle; The axial projection of 2 is petal-shaped, the center forms a truncated cone 4 with a throttle hole 3, and four petals 5 are formed around the petals, between the petals, between the petals and the truncated cone, and between the petals and the valve body.

[0024] In this embodiment: the valve body 1 and the valve core 2 are made of a section of red copper pipe. Such as figure 1 As shown, the valve core 2 is located in the middle of the copper tube, and the valve body 1 is formed at both ends of the copper tube. Such as figure 2 As shown, the valve core 2 is in the shape of a "cross" with four petals (arms) 5, the center of the "cross" shape forms a circular table 4, and the c...

specific Embodiment 2

[0037] The characteristic of this embodiment 2 is that the number of petals 5 is three, which is in the shape of three leaves. The valve body is cylindrical, the diameter of the cylinder is large and small, and the shape of the joints at both ends of the cylinder is consistent with the matching position of the whole machine, which is determined according to the needs of the whole machine. The position of the spool in the cylinder is determined according to the matching of the whole machine. The rest is the same as in Example 1.

specific Embodiment 3

[0038] The characteristics of this embodiment 3 are: the number of petals 5 is five, which is in the shape of five leaves. The rest is the same as in Example 1.

Abstract

The invention relates to a protruding integrated throttle valve, which includes a valve body and a valve core, and its structural features are: the valve body (1), the valve core (2) and the throttle hole (3) in the valve core are integrally formed; It is stamped and formed by a copper tube, and the two ends of the formed throttle valve are the valve body (1), and a section of conical valve core (2) with a throttle hole (3) is formed in the middle; the axial projection of the valve core (2) is It is petal-shaped, with a round platform (4) in the center and several petals (5) around it, and the petals, between the petals and the round platform, and between the petals and the valve body are connected as a whole. Because the present invention changes the split structure of the original short-pipe throttle valve or the plate-hole throttle valve into an integrated structure, there is no gap between the valve core and the valve body, which greatly improves the deformation resistance of the throttle valve. Anti-leakage and anti-leakage capabilities, good flow consistency, stable and reliable performance; at the same time, the structure of the throttle valve is simplified, the consumption of raw materials is reduced, and the cost is saved. Therefore, it has epoch-making significance and is suitable for popularization and application.

Description

Technical field [0001] The invention relates to a throttle valve, in particular to a convex integral throttle valve. It belongs to the technical field of throttling devices in refrigeration equipment. Background technique [0002] The throttle valve is the throttling component of the refrigeration system, which directly affects the quality of the refrigeration effect. There are many throttling methods in the prior art, including capillary throttling, short tube throttling valve throttling, or plate hole throttling valve throttling. [0003] The capillary throttling has the following shortcomings: (1) The processing technology is complex, the product is difficult to meet the design requirements, and the complicated process can easily cause inconsistent capillary apertures and semi-blocking or full blockage at the weld. (2) The capillary tube is long, the overall volume is large, the consumables are many, and the cost is high. (3) Vibration and noise are easily generated. [0004] ...
