Abstract
This invention is a motorized valve that is used to adjust refrigerant quantity of refrigerating system. The holding cavity is arranged with cooperated lead screw and nut, in order to change the magnet rotation into radial movement of valve needle. The nut includes upper guiding hole, lower guiding hole and intermediate internal thread section. The lead screw includes upper guiding section, low guiding section and intermediate external thread section. The said external and internal thread sections are cooperated. The said upper and lower guiding sections are located in the upper and lower guiding holes. Both sides of nut internal thread sections are arranged with guiding holes that are used to guide the lead screw. Thus, the screw thread section is freed from guiding the lead screw. It avoids the impact of magnet vibration and increases the abrasion resistant capability of thread section.
Description
Technical field
The present invention relates to the refrigeration system parts, specifically a kind of mortor operated valve of regulating cold medium flux.
Background technique
At present common mortor operated valve as shown in Figure 1, comprise valve body 6, coil (not marking), screw mandrel 2 and magnet 3 integrated injection moldings, screw mandrel 2 are provided with guide section 16 and external thread section 14, with screw mandrel 2 nut engaged 4 last pilot hole 17 (position corresponding with guide section on the screw mandrel 16), internal thread segment 14 are arranged.Internal thread segment 15 on the nut 4 cooperate with external thread section 14 on the screw mandrel 2 make the described coil of magnet 3 responses electromagnetic field and the circular movement done changes into the straight line motion of needle 10, thereby by needle 10 away from or the circulation area of regulating valve port 9 near valve port 9 with the taking over 7 from and flow to another and take over 8 flow of variable expansion valve, reduce the vibration of magnet 3 simultaneously by the guiding of 4 pairs of screw mandrels 2 of nut.Said structure since only on the upside setting of the internal thread segment 15 of nut 4 and screw mandrel guide section 16 corresponding on pilot hole 17, this internal thread segment 15 also participates in the guiding to screw mandrel when action, therefore less to the matching gap requirement between the external thread section 14 of the internal thread segment 15 of nut 4 and screw mandrel 2, but inevitably the magnet vibration has still caused wear-resisting property unfavorable of double thread, and fine impurities easily causes screw thread stuck in the screw thread, and refrigeration system inside also requires to avoid as far as possible the generation of fine impurities simultaneously.
Summary of the invention
Technical problem to be solved by this invention be overcome that above-mentioned prior art exists because of screw thread need participate in the guiding of screw mandrel is required the less defective that causes its wear-resisting property difference of its matching gap, a kind of mortor operated valve that the reliable guiding of screw mandrel is strengthened the screw thread wear-resisting property by nut is provided.For this reason, the present invention is by the following technical solutions:
A kind of mortor operated valve, comprise valve body and coil, on valve body, be connected with two adapters, in valve body, offer the valve port between two adapters, above described valve port, be formed with receiving cavity, and in receiving cavity, dispose the magnet of the needle corresponding, the described coil electromagnetism of perception field and, in described receiving cavity, be provided with nut with the screw mandrel that magnet rotates with described needle with described valve port; It is characterized in that: described nut comprises pilot hole, following pilot hole and middle internal thread segment; Described screw mandrel includes guide section, following guide section and middle external thread section; Described external thread section cooperates with the internal thread segment of described nut, and the last guide section of described screw mandrel, following guide section lay respectively in the last pilot hole of described nut, the following pilot hole and be Spielpassung.
As the further of technique scheme improved and replenish, the present invention also comprises following additional technical feature:
Described mortor operated valve is characterized in that: the last guide section of described screw mandrel, down guide section and the last pilot hole of corresponding described nut, the gap between time pilot hole be less than the gap between directly directly and in the internal thread segment in the external thread section.
Described mortor operated valve is characterized in that: offer radial hole on the described nut.
Described mortor operated valve is characterized in that: the axis of the relative nut of radial hole on the described nut is and is symmetrical arranged.
Described mortor operated valve is characterized in that: the radial hole on the described nut is positioned at the following pilot hole of nut and the adjacent regions of internal thread segment.
The present invention all is provided with the pilot hole that screw mandrel is led by the both sides in the internal thread segment of nut, thereby thread section can be freed in the effect that screw mandrel is led, avoid bearing the impact of magnet vibration, can strengthen the wear-resisting property of thread section thus; Further, the gap between the respective threaded section is increased to strengthen the wear-resisting property of thread section, the wearing and tearing that reduce because of screw thread produce fine impurities; In addition, the present invention also has following technique effect: the screw thread two ends are provided with the guiding of less matching gap, can prevent effectively that impurity from sneaking into screw thread and causing valve stuck; There are the less following guiding in gap in screw mandrel and nut, can effectively reduce the shake of needle, thereby reduce the wear resistance of the noise and the raising valve port of valve.

Embodiment
Mortor operated valve as shown in Figure 2, comprise valve body 6 and the coil (not shown) that is arranged on the appropriate location, on valve body 6, be connected with two and take over 7,8, in valve body 6, offer the valve port of taking between 7,8 at two 9, above valve port 9, be formed with receiving cavity 5, and in receiving cavity 5, dispose the magnet 3 of the needle 10 corresponding, perception coil electromagnetism field and the screw mandrel 2 that rotates with magnet 3, in receiving cavity 5, be provided with nut 4 with needle 10 with valve port 9; The difference of this structure and existing structure is: nut 4 (seeing Fig. 3 for details) comprises pilot hole 17, following pilot hole 12 and middle internal thread segment 15; Screw mandrel 2 (seeing Fig. 4 for details) includes guide section 16, following guide section 11 and middle external thread section 14; External thread section 14 cooperates with the internal thread segment 15 of nut 4, and the last guide section 16 of screw mandrel 2, following guide section 11 lay respectively in the last pilot hole 17 of nut 4, the following pilot hole 12 and be Spielpassung.Thus screw thread is freed in the effect that screw mandrel is led.
In more detail, the last guide section 16 of screw mandrel, down guide section 11 and corresponding last pilot hole 17, the gap between time pilot hole 12 be less than the gap between directly directly and in the internal thread segment 15 in the external thread section 14, so that double thread cooperates flexibility that very big benefit is arranged, bigger thread pitch double thread wear resistance is also highly beneficial; Offer radial hole 13 on the nut 4, the axis of these radial hole 13 relative nuts is and is symmetrical arranged, and this radial hole is the best with the adjacent regions of the following pilot hole 12 that is positioned at nut and internal thread segment 15, guarantees thread section equal pressure up and down.
