Abstract
A self-operated pressure regulating valve in a soft sealing structure belongs to the technical field of self-operated pressure regulating valves and comprises a valve body, a valve cover and an actuating mechanism. A valve core and a valve rod which are fixed together are arranged in the valve body and the valve cover in connecting mode. The bottom of the valve core can be matched with a valve seat fixedly arranged in the valve body. A corrugated pipe playing a role of a balance element is arranged at the upper end of the valve core in sleeving mode. The upper end of the valve rod is connected with the actuating mechanism, and a spring seat fixedly arranged on the valve rod is elastically connected with an adjusting disc arranged on a valve cover. A pressing gasket is connected with the lower end of the valve core in sleeving mode, a soft sealing valve clack is arranged at the upper end of the pressing gasket in embedding mode and fixed with a nut vertically in clamping mode through an arranged sealing seat, and an inclined sealing face on the outer side of the soft sealing valve clack exceeds an outer side edge of the pressing gasket. The valve core of the self-operated pressure regulating valve in the soft sealing structure adopts the inclusive soft sealing structure, firmly wraps the soft sealing valve clack through a sealing seat and the pressing gasket only with the inclined sealing face reserved, and prevents the valve clack from being flushed, thereby being good in sealing performance.
Description
Technical field
The utility model belongs to the self-contained pressure regulator technical field, is specifically related to a kind of self-contained pressure regulator of soft sealing structure.
Background technique
Self-contained pressure regulator need not external energy (need not additional power source or source of the gas), utilizes and is transferred the medium self-energy as power source; Introduce the actuating mechanism controls valve element position; Change circulation area, change the pressure reduction at two ends, thereby make downstream pressure be stabilized in setting value.Have and be active in one's movements, good airproof performance, characteristics such as pressure surge is little, and return difference is little are widely used in the various industry equipments the automatic control occasion to gas, liquid decompression voltage stabilizing.
In recent years, the develop rapidly of domestic valve industry, the product structure type of each valve producer emerges in an endless stream.But domestic existing self-contained pressure regulator soft seal valve mechanism is unreasonable, and flap is washed away easily, and is not wear-resisting, and shortcomings such as resistance to high temperature is poor, corrosion-resistant influence the sealability of valve; Domestic soft sealing material is mainly teflon, all kinds of rubber etc. at present, and its flap is washed away easily, and resistance to high temperature is poor, can not under the operating mode of high temperature, use; Some operating mode bans use of teflon; Under the situation that the both can not satisfy, can only select hard sealed valve for use; But there is certain leakage all the time in the valve of hard sealing, and the rising of valve leak pressure can produce the phenomenon that builds the pressure, and gives the usability deleterious impact of valve.
The model utility content
To the problem that existing technology exists, the purpose of the utility model is to design the technological scheme of the self-contained pressure regulator that a kind of soft sealing structure is provided.
The self-contained pressure regulator of described a kind of soft sealing structure; Comprise valve body, valve gap and actuator, be connected in described valve body and the valve gap spool and the valve rod that is fixed together is set that described spool bottom can be equipped with the valve seat that is fixedly installed in the valve body; The bellows of described spool upper end socket setting plaing balancing component effect; The upper end connection of described valve rod is provided with actuator, and fixedly installs spring seat on the described valve rod, and the connection of spring seat elasticity is arranged on the adjustment disk on the valve gap; It is characterized in that the lower end socket of described spool is provided with compress gasket; The compress gasket upper end is embedded the soft seal flap, and the soft seal flap is fixedly clamped up and down through sealing seat and the nut that is provided with, and the inclination sealing surface in the soft seal flap outside surpasses the outer ledge of compress gasket.
The self-contained pressure regulator of described a kind of soft sealing structure is characterized in that between described compress gasket and the nut elastic washer being set.
The self-contained pressure regulator of described a kind of soft sealing structure is characterized in that described nut and spool lower end fix through safety pin.
The self-contained pressure regulator of above-mentioned a kind of soft sealing structure; Spool adopts the containment soft sealing structure, through sealing seat and compress gasket the soft seal flap is firmly wrapped up and only reserves the inclination sealing surface, prevents that flap from being washed away; Valve seal property is good; And the soft seal flap adopts soft seal new material contraposition polyphenyl (PPL) to process, its at high temperature, high pressure, have burn into to have under the special operating mode such as radiation to use, serviceability temperature reaches as high as 280 ℃; Keep good sealing property, can reach zero leakage.
