Valve capable of reducing pressure shock

Abstract

The invention relates to a valve capable of reducing the pressure shock. The valve capable of reducing the pressure shock comprises a valve shell, wherein a water inlet and a water outlet are formed in the bottom part of the valve shell; a valve block is arranged in the valve shell; the opening end of the bottom part of the valve block can be movably connected with a compensating plate; two blockage blocks are fixedly connected to the bottom surface of the compensating plate; a preloaded spring is connected and fixed between the surface of the compensating plate and the seal end of the valve block; a drive spring is distributed on the surface of the valve block and is fixedly connected with a pressurizing device through connecting rods; the pressurizing device comprises a one-way air release valve and is arranged on a support plate; the bottom part of the support plate is fixedly connected with the valve shell through a connecting support; an upper seal plate is arranged on the bottompart of the one-way air release valve; a lower seal plate is arranged under the upper seal plate; a gap is formed between the lower seal plate and the upper seal plate; the bottom surface of the lowerseal plate is fixedly connected with the connecting rods; and heat conducting rods are arranged at two ends of the upper seal plate. According to the valve capable of reducing the pressure shock provided by the invention, the valve flow rate is controlled, and meanwhile, the pressure shock on the valve is weakened.

Description

technical field [0001] The invention relates to a valve for reducing pressure shock, which belongs to the field of valves. Background technique [0002] Valves are pipeline accessories used to open and close pipelines, control flow direction, adjust and control the parameters (temperature, pressure and flow) of the conveying medium. According to its function, it can be divided into shut-off valve, check valve, regulating valve and so on. [0003] The valve is a control component in the fluid delivery system, which has functions such as cut-off, adjustment, flow diversion, reverse flow prevention, pressure stabilization, flow diversion or overflow pressure relief. Valves used in fluid control systems range from the simplest cut-off valves to various valves used in extremely complex automatic control systems, with a wide variety of varieties and specifications. [0004] Valves can be used to control the flow of various types of fluids such as air, water, steam, various corro...

AI Technical Summary

Problems solved by technology

When the gas cylinder is deflated and used to the set pressure, the valve can be automatically closed to prevent the air from entering the cylinder after the gas in the cylinder is completely used up, so as to ensure the purity of the gas in the cylinder, and there is no need to carry out the gas cylinder when inflating. Vacuum treatment saves production cost; but the problem with the above valve structure is that the structure is complex, and the pressure impact on the valve cannot be weakened when the flow rate is too large
