Abstract
A gate valve clack fixing structure comprises a valve clack and locating blocks mounted in the valve clack. The valve clack comprises a containing groove for containing the locating blocks and two anti-disengaging blocks formed on the side wall of a locating groove. Each locating block comprises two clamping and stopping blocks which abut against the two anti-disengaging blocks in the axial direction, and a receding groove for allowing the corresponding anti-disengaging block to pass through is formed between the two clamping and stopping blocks. The gate valve clack fixing structure further comprises locating clamps arranged in the receding grooves. According to the gate valve clack fixing structure, a clamped and combined mode is adopted, the valve clack can be integrally formed, a thread does not need to be machined in the valve clack, threads do not need to be additionally machined on the locating blocks, and screws do not need to be additionally arranged, so that the gate valve clack fixing structure is more convenient to machine and manufacture and lower in machining and manufacturing cost.
Description
Technical field
The present invention relates to a kind of fixed structure, particularly relate to a kind of gate valve flap fixed structure.
Background technology
Current gate valve flap fixed structure is generally adopted threaded mode, by nut precession flap, then bores two screwed holes in end-face helical seam crossing symmetry, loads limit screw, it is prevented that spiral shell rotates.But, such structure is complex, manufactures processing cost higher.
Summary of the invention
For above-mentioned existing problem, it is an object of the invention to provide a kind of lower-cost gate valve flap fixed structure.
For reaching above-mentioned technique effect, the technical solution used in the present invention is: a kind of gate valve flap fixed structure, including flap and be arranged on the locating piece in flap.This flap includes the holding tank of accommodation locating piece and forms two stop blocks at locating slot sidewall, this locating piece includes two stop blocks leant in the axial direction with these two stop blocks, being formed for, between these two stop blocks, the bit-avoiding slot that stop block passes through, this gate valve flap fixed structure also includes the locator card being arranged in bit-avoiding slot.
The gate valve flap fixed structure of the present invention adopts the mode of engaging, and flap can be one-body molded, it is not necessary to process screw thread in inside, and without additional processing screw thread on locating piece and additionally arrange screw, processing and manufacturing is more convenient, and processing and manufacturing is lower in cost.
Accompanying drawing explanation
Fig. 1 is the sectional view of gate valve flap fixed structure.
Fig. 2 is the top view of the fixed structure of gate valve flap shown in Fig. 1.
Detailed description of the invention
Below in conjunction with accompanying drawing, the gate valve flap fixed structure of the present invention is described further.
Referring to Fig. 1 and Fig. 2, the gate valve flap fixed structure of the present invention includes flap 1, locating piece 3 and locator card 2.Wherein, flap 1 offering the holding tank holding locating piece 3 and locator card 2, holding tank is generally cylindrical, and flap 1 is formed with the stop block extended towards holding tank center on the sidewall of holding tank near the position at top, is used for preventing locating piece 2 from deviating from.Outer peripheral face bottom locating piece 3 is formed the stop block corresponding with stop block.It is formed with bit-avoiding slot, for passing through for stop block between two stop blocks.Locator card 2 shape is substantially corresponding to bit-avoiding slot, is arranged in bit-avoiding slot to prevent the rotation of locating piece 3 after being arranged on flap 1 for locating piece 3.
During installation, locating piece 3, in the holding tank loading flap 1 in the way of bit-avoiding slot is just to stop block, then rotates 90 degree, makes the stop block of flap 1 and stop block axially the abutting at locating piece of locating piece 3, be fixed in the axial direction.Then loading in bit-avoiding slot by locator card 2, the stop block of locator card edge and flap 1 abuts, it is prevented that the rotation of locating piece 3.So, just locating piece 3 is fixed in holding tank, completes to be connected with the fixing of flap.
The gate valve flap fixed structure of the present invention adopts the mode of engaging, and flap can be one-body molded, it is not necessary to process screw thread in inside, and without additional processing screw thread on locating piece and additionally arrange screw, processing and manufacturing is more convenient, and processing and manufacturing is lower in cost.
The above; preferably case study on implementation for the present invention; not the present invention is imposed any restrictions, every any simple modification, change and equivalent structure change above example made according to the technology of the present invention essence, all still fall within the protection domain of technical solution of the present invention.
