An integrated structure of the transmission rod and the valve needle of the expansion valve The utility model provides an integrated structure of the transmission rod and the valve needle of the expansion valve, the lower end of the transmission rod in the valve body is integrated with the valve needle, and the valve The needle is in contact with the cylindrical adjustment spring at the bottom through the valve needle seat, and an adjustment rod is threaded through the middle of the cylindrical adjustment spring. The adjustment rod is covered with an adjustment nut, and a transmission block is placed on the top of the transmission rod, and the transmission block is located under the diaphragm. . The advantage of the utility model is the integrated design of the transmission rod and the valve needle, which effectively solves the valve port wear caused by the skew of the valve needle, the refrigerant flow rate is inconsistent, and the valve needle shakes; and then the valve needle seat is integrated with the valve needle The modernized design and the trinity effectively avoid the hidden danger of the traditional valve needle being separated from the valve needle seat.
Description
Technical field
The utility model relates to a kind of structure of the valve inner that expands, and the particularly incorporate structure of a kind of drive link of expansion valve and needle belongs to the throttling technology field of refrigeration system.
Background technique
Heating power expansion valve is one of throttle element the most frequently used in the existing refrigeration system, and it plays a part the throttling step-down in whole refrigeration system.
As shown in Figure 1 be a kind of conventional heating power expansion valve.The temperature of evaporator outlet in bulb 1 sensory perceptual system, when temperature raises, the variation in pressure that produces with temperature by gas that fills in the bulb or liquid, make diaphragm 3 distortion of unit head 2 the insides, two drive links 6 that drive block 4 passes to valve body 5 will be moved through, drive link 6 promotes needle seat 7, needle seat 7 press fit over needle 8, the thrust of adjustable lever 10 and the 9 power actings in conjunction of following spring, change the flow area of needle 8 and valve port, thereby change cold medium flux by expansion valve.Bulb 1 sense temperature raises, and valve opening increases, and reduces the system overheat degree, and on the contrary, bulb 1 sense temperature is low, and then valve opening reduces, and the degree of superheat of system increases.Equally, adjustable lever 10 Regulation spring power can be passed through to change the valve port flow area and the degree of superheat of regulating system equally.
The model utility content
Technical problem of the present utility model is will provide a kind of to prevent that needle is crooked and cause the valve port wearing and tearing and prevent the drive link and the incorporate structure of needle of the expansion valve of the inconsistent expansion valve choke pressure fluctuation that causes of drive link transferring power.
In order to solve above technical problem, the utility model provides a kind of drive link and incorporate structure of needle of expansion valve, drive link lower end and needle in the described valve body are connected as a single entity, needle contacts with the cylindricality Regulation spring of bottom by the needle seat, one adjustable lever is worn the middle part of going here and there in the cylindricality Regulation spring, adjustable lever is with adjusting nut outward, and the top of drive link is placed with drive block, and drive block is positioned at the below of diaphragm.
Described needle contacts with the cylindricality Regulation spring of bottom by the needle seat:
1), the needle seat has groove, needle places in this groove, both can separate;
2), the needle seat is the T font, needle and needle seat are connected as a single entity.
Superior effect of the present utility model is:
1) drive link and needle integrated design have solved effectively because the valve port of the crooked generation of needle weares and teares, and refrigerant flow is inconsistent, and the needle that produces shake;
2) again with needle seat and needle integrated design, the three-in-one has been avoided the traditional needle and the hidden danger of needle seat disengaging effectively.

Embodiment
See also shown in the accompanying drawing, the utility model will be further described.
As Fig. 2, Fig. 3 and shown in Figure 4, the utility model provides a kind of drive link and incorporate structure of needle of expansion valve, drive link 6 lower ends and needle 8 in the described valve body 5 are connected as a single entity, needle 8 contacts with the cylindricality Regulation spring 9 of bottom by needle seat 7, one adjustable lever 10 is worn the middle part of going here and there in cylindricality Regulation spring 9, be with adjusting nut 11 outside the adjustable lever 10, the top of drive link 6 is placed with drive block 4, and drive block 4 tops are diaphragms 3.
Described needle 8 contacts with the cylindricality Regulation spring 9 of bottom by needle seat 7, and needle seat 7 is realized by following two kinds of structures::
1), needle seat 7 has groove, needle 8 places in this groove, both can separate;
2), needle seat 7 is T fonts, needle 8 is connected as a single entity with needle seat 7.
The utility model removes two traditional drive links, adopts a drive link 6 and needle 8 integrated designs, is machined to the size and the surface accuracy that need.Drive block 4 directly passes to motion to needle 8, regulates the aperture of valve port, in the upper end of drive link 6, with valve body 1 Spielpassung, has guaranteed that needle 8 motions can be not crooked.
