Description

High-pressure-bearing iron sheet buckle type plastic ball valve Technical Field The utility model relates to the technical field of valves, in particular to a high-pressure-bearing iron sheet buckle type plastic ball valve. Background In various pipeline systems, ball valves are widely applied due to unique advantages, and the key tasks of cutting off, distributing, adjusting flow, changing medium flow direction and the like are borne, and the working principle is that the valve ball is driven by rotating a valve rod to realize the unblocking or blocking of the valve. Because the cost is considered in the joint in the market, the joint is increasingly made of plastic, the bearing capacity is poor, the valve core can displace or deviate from after being subjected to multiple water hammers or instantaneous high pressure, and liquid leakage is caused. Disclosure of utility model The utility model aims to solve the problems in the background art and provides a high-pressure-bearing iron sheet buckle type plastic ball valve. The technical scheme includes that the high-pressure-bearing iron sheet buckle type plastic ball valve comprises a valve body, wherein an installation cavity for installation is formed in the valve body, an annular groove I for clamping is formed in the inner wall of the installation cavity, a clamping groove is formed in the installation cavity, an iron buckle for reinforcement is arranged in the clamping groove, a valve core for controlling water flow is arranged in the installation cavity, and an annular groove II for accommodating the iron buckle is formed in the outer wall of the valve core. Optionally, a chamfer protrusion is arranged on the outer part of the valve core, and the chamfer protrusion is matched with the first annular groove. Optionally, the outside of case is equipped with mounting groove one and two mounting grooves two, mounting groove one and two mounting grooves two are equipped with first sealing washer and second sealing washer respectively. Optionally, the top of valve body is equipped with the handle, the fixed spacing collar that is equipped with in bottom of handle, be equipped with the spacing groove on the spacing collar, the inner wall of spacing collar is equipped with interior conical surface, the top of valve body is equipped with the bulge, bulge and interior conical surface looks adaptation. Optionally, the bottom of handle is fixed and is equipped with the inserted bar, the top of case is equipped with the jack with inserted bar assorted. Optionally, the top outer wall of valve body is equipped with the stopper, the height of stopper is the same with the height of spacing groove. Optionally, the insert rod and the jack are both semicircular. Compared with the prior art, the utility model has the following beneficial technical effects: 1. According to the utility model, through the arrangement of the annular groove I and the chamfer bulge, the primary fixation of the valve ball can be realized, the arrangement of the iron buckle can share the axial force born by the back-off structure, so that the valve core is prevented from axial displacement or even ejection due to fluid impact or vibration, and the reinforcement purpose is realized. 2. According to the utility model, through the arrangement of the first sealing ring and the second sealing ring, the double sealing effect can be achieved, and the liquid leakage can be effectively prevented.
