Description

Impact-resistant flat valve Technical Field The utility model relates to the technical field of valves, in particular to an impact-resistant flat valve. Background The flat valve is a cut-off valve with simple structure and rapid opening and closing, the core component is a flat valve plate, the opening and closing are realized through the linear motion of the valve plate perpendicular to the flow direction of a medium, the valve adopts a plane sealing structure, has the characteristics of small flow resistance, good sealing performance, convenient maintenance and the like, is suitable for various medium pipeline systems in industries such as petroleum, chemical industry, electric power and the like, is especially suitable for working conditions containing solid particles or high-viscosity fluid, and has shorter opening and closing stroke and stronger anti-scouring capability compared with the traditional gate valve, and the compact design of the flat valve also saves installation space. The chinese patent of current publication No. CN206889714U discloses a flat gate valve, the flashboard slides along vertical direction and sets up in the valve body and can slide control valve about the valve body inner wall and open and close, two disk seats set up respectively in the valve body of flashboard both sides, the disk seat slides along horizontal direction and sets up in the appearance intracavity of the valve body through-hole tip in the valve body and can freely slide along appearance intracavity wall, wave spring sets up at disk seat one end tip and wave spring both sides support respectively and lean on valve body inner wall and disk seat on provide horizontal direction thrust to the disk seat, the brake lever is vertical to be set up in the valve body and brake lever lower extreme and flashboard fixed connection, the valve gap is fixed in the valve body upper end, the brake lever nut rotates and sets up in the valve gap and brake lever nut cover is established in brake lever upper end and brake lever threaded connection, the hand wheel is fixed in the brake lever nut outside. The utility model realizes sealing by matching the valve seat with the wave spring and the flashboard, thus being irrelevant to the pressure of the medium and not affected. Above-mentioned scheme and flat valve under the prior art utilize valve rod screw thread lift control valve plate to reciprocate between two sets of disk seats and control opening and close of valve to control the passage of inflow medium and block, current valve plate mostly are integral type structure, and it is easily impacted and worn and torn by the medium with the disk seat contact surface, leads to sealing performance to drop and after long-term use the valve plate yielding, influences the valve function of opening and close, lacks corresponding shock-resistant valve plate structure in the flat valve to here, need improve and optimize. Disclosure of utility model The present utility model is directed to a flat valve with impact resistance, which solves the problems set forth in the background art. In order to achieve the purpose, the impact-resistant flat valve comprises a valve plate main body, wherein one end of the valve plate main body is provided with a clamping groove, one end of the valve plate main body is provided with a through hole, two ends of the valve plate main body are symmetrically provided with slots, an impact-resistant combined plate is inserted into each slot, one end of the valve plate main body is provided with an operation groove, two ends of the operation groove are symmetrically provided with first threaded holes, and the first threaded holes are in threaded connection with two-way fixing screws. Preferably, a sealing groove is formed in the inner wall of the slot, and a sealing strip is inserted in the sealing groove. Preferably, buffer rubber blocks are symmetrically inserted into two ends of the valve plate main body, and a screw cap is arranged in the middle of the bidirectional fixing screw. Preferably, the impact-resistant combined plate comprises a steel substrate, a honeycomb metal buffer layer and a tungsten carbide alloy surface layer, wherein one end of the steel substrate is fixedly connected with the honeycomb metal buffer layer, one end of the honeycomb metal buffer layer is fixedly connected with the tungsten carbide alloy surface layer, and the other end of the steel substrate is extruded on a buffer rubber block. Preferably, one end of the impact-resistant composition board is provided with a second threaded hole. Preferably, one end of the second threaded hole is in threaded connection with a bidirectional fixing screw rod, the inner wall of the second threaded hole is fixedly connected with a spring, and the other end of the spring is extruded on the bidirectional fixing screw rod. Compared with the prior art, the utility model has the beneficial effects that: the impact-resistant flat valve mainly comprises slots
