The invention relates to a warm-box. The warm-box comprises an outer box body made of flexible material and a warm support plate arranged in the outer box body. The warm support plate comprises a bottom plate, a covering plate and front, back, left and right vertical plates, wherein the front, back, left and right vertical plates are connected with all sides of the bottom plate through the flexible material. The front and back vertical plates are folded inward along with the front and back edges of the bottom plate respectively and the front and back vertical plates are suitable for being tiled on the bottom plate at the same height. The left and right vertical plates are folded inward along with the left and right edges of the bottom plate respectively and the left and right vertical plates are suitable for being tiled on the front and back vertical plates at the same height. When the front, back, left and right vertical plates corresponding to the bottom plate are in upright position, the outer box body is putted up and forms a cavity of the warm-box. The covering plate is used for covering the top opening of the cavity and all-around edges of the covering plate locate at the tops of the front, back, left and right vertical plates. As parts of the box body are compressed into plate blocks and are carried respectively, the space occupation of the parts is relatively small. When the parts of the box body are unfolded and used, the operation is facilitated.

The invention relates to a method for cleaning the seat of a double seat valve (1) and a double seat valve (1) for performing the method, which, even if the cross-sectional surface of the discharge bore is smaller than that of the largest tube conduit that can be connected to the double seat valve, ensure that the seat cleaning flow is guided to the greatest possible extent without swirling into and out of the leakage cavity, and reliably avoid a pressure-increasing, direct impact on the seat regions. This is technically achieved in that the first seat cleaning flow (R1) is urged by the deflection surface (4d) radially inwards and axially towards the first closing member (3) until it leaves the second closing member (4) at a frontally and radially internal end (4e) of the second closing member (4), which end is located outside the recess (4b). The double seat valve (1) for performing the method is characterised in that the deflection surface (4d) borders in its entirety the remaining region of the recess (4b) that is not delimited by the circumferential wall (4c) and opens out from the second closing member (4) at a front and radially internal end (4e) thereof that faces the first closing member (3).

The invention discloses a coupling counteracting path branch knot and a high-isolation millimeter wave phased array antenna based on the coupling counteracting path branch knot. The high-isolation millimeter wave phased array antenna comprises a plurality of radiation laminated microstrip antenna units, a shielding metal wall, a plurality of coupling offset path branches, a metal floor, a feed network layer, a first port and a second port; the first port is excited, the energy of the feed network layer is coupled to the corresponding radiation laminated microstrip antenna unit through the I-shaped gap, and the energy is transmitted to the second port adjacent to the first port through the inherent coupling path part; and the coupling offset path branch knot is introduced to offset the inherent coupling path, so that the high isolation effect between the first port and the second port is realized. Due to the adoption of the simple decoupling branches, the broadband high isolation effect can be realized, the active standing-wave ratio in a working frequency band and the scanning capability of the array antenna are improved, and the antenna has the advantages of compact structure and simple design.

The invention discloses a crimping device for a steel-cored aluminum stranded wire. The crimping device comprises a first mounting ring, a second mounting ring arranged at a lower part of the first mounting ring, and sliding rods symmetrically arranged on one side of the first mounting ring and one side of the second mounting ring, and a crimping cylinder is clamped between the first mounting ringand the second mounting ring; a sliding block is arranged on each sliding rod, a clamping hook is arranged on one side of the sliding block, and a connecting buckle is arranged at one end of a pressing rod; and a first clamping ring is arranged at the lower end of the upper sliding block, a second clamping ring is arranged at the upper end of the lower sliding block, a connecting device is arranged between a first grip and a second grip, and a stranded wire body is arranged between the first clamping ring and the second clamping ring. In the invention, the crimping cylinder is clamped in thefirst mounting ring and the second mounting ring; and the sliding rods are arranged on one side of the first mounting ring and one side of the second mounting ring, the sliding block is arranged on each sliding rod, the pressing rod is arranged on the upper portion of the sliding rod, the pressing rod is used for pushing the sliding block, the stranded wire body is pushed into the crimping cylinder step by step, stress uniformity of the stranded wire body is guaranteed, and technical difficulty of construction personnel is reduced.
