Detailed Description
The invention will be further described with reference to the accompanying drawings and specific embodiments. The technical solutions in the embodiments of the present invention are clearly and completely described, and the described embodiments are only some embodiments of the present invention, not all embodiments of the present invention. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments of the present invention without any creative effort belong to the protection scope of the present invention.
As shown in fig. 1 and 2, the utility model discloses an embodiment of gate valve blank, whole gate valve blank are right angle three way type, and the level of inclusion leads to chamber 1 and vertical control chamber 2, and the level leads to chamber 1 and is straight cylindrical, and its both ends are equipped with flange board 3 respectively, and the flange of gate valve can be regarded as in the 3 trompils of flange board. The whole of control chamber 2 is nearly square column shape, from the perpendicular horizontal middle part that leads to chamber 1 of intercommunication of upside, the long chamber wall in its both sides is the slight arc of symmetry and draws together outward, and the chamber wall thickening of 2 corners in control chamber, the top is turned up perpendicularly and is formed border 4, and 4 trompils in border regard as the connecting seat of valve gap.
Four corners of the lower surfaces of the two short sides of the edge 4 are respectively provided with a first reinforcing lug 5, the middle parts of the lower surfaces of the two long sides are respectively provided with a long second reinforcing lug 6, and the first reinforcing lug 5 and the second reinforcing lug 6 are simultaneously connected with the cavity wall of the cavity 2 and the lower surface of the edge 4.
The inner side surfaces of two short cavity walls of the control cavity 2 are symmetrically provided with vertical raised gate plate slideways 10, and the bottoms of the gate plate slideways 10 extend to the position below half of the horizontal through cavity 1.
