specific Embodiment 1

[0022] refer to figure 1 , This embodiment includes a valve body 1 and a valve core 2, and its structural features are: the valve body 1 and the valve core 2 are extruded from a copper tube, forming an integral structure; the two ends of the formed throttle valve are the valve body 1. A valve core 2 is formed in the middle; a ring platform 4 with an orifice 3 is formed in the center of the valve core 2, and the periphery is connected with the valve body 1 as a whole.

[0023] In this embodiment, the valve body 1 and the valve core 2 are made of a section of red copper tube, the valve core 2 is located in the middle of the red copper tube, and the two ends of the red copper tube form the valve body 1 . The front of the valve core 2 is convex and is frustoconical, its axial section is an isosceles trapezoid, the end face of the ring platform 4 is circular, and the throttle hole 3 is located at the center of the ring platform 4; The back is concave and its shape is complementary...

specific Embodiment 2

[0024] The characteristics of this specific embodiment are: the two ends of the valve core 2 are platform-shaped, the valve body is cylindrical, the diameter of the cylinder is large and small, and the shape of the interface at both ends of the cylinder matches the matching position of the whole machine. , according to the needs of the whole machine. The position of the valve core in the cylinder is determined according to the matching of the whole machine. The rest are the same as in Example 1.

[0025] The manufacturing method of the present invention is as follows: prepare the red copper tube as required, place the red copper tube in a special mold, extrude it at one time with an extruder, and use a machine to extrude from both ends of the copper tube to the middle during extrusion, The valve core 2 is formed by extruding the inner cavity of the copper tube. The size and shape of the valve core 2 can be set as required. The size and shape of the valve core 2 and the valve ...

Abstract

The invention relates to an inward protruded integrated throttle valve, which comprises a valve body (1) and a valve core (2). It is characterized in that: the valve body (1) and the valve core (2) are integrated molded by copper pipe compression; the ends of throttle valve molded are valve bodies (1), while its center is the valve core (2); the center of valve core (2) has a rotary table (4) with throttle holes (3) while its edge is integrated with valve body (1). The invention replaces former short-pipe throttle valve or plate-hole throttle valve with integrated structure to avoid the space between valve core and valve body to improve the anti-deformation and the anti-leakage abilities of throttle valve, with stable property, reduced raw material consumption and lower cost.

Description

technical field [0001] The invention relates to a throttle valve, in particular to an internal convex integrated 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 is directly related to the quality of the refrigeration effect. There are various throttling methods in the prior art, including capillary throttling, short-pipe type throttling valve throttling or plate hole type throttling valve throttling and the like. [0003] Capillary throttling has the following disadvantages: (1) The processing technology is complex, and the product is difficult to meet the design requirements. The complex process can easily cause inconsistent capillary apertures, and half or full blocking at the weld. (2) The capillary pipeline is long, the overall volume is large, the consumables are many, and the cost is high. (3) It is easy ...
