Description
Technical field
The utility model relates to the design and the manufacturing of valve; Be widely used in the industrial pipeline, particularly automatically in the instrumentation pipelines such as all kinds of flows in the control, differential pressure, pressure, liquid level poisonous, radioactivity and inflammable and explosive liquid or the keying of gas and the valve of control arranged.
Background technique
In the conventional valves structure; All adopt filler to prevent the sealing of external leakage; Owing between filler and valve rod, the valve gap inevitable kinetic friction factor is arranged; So structurally still exist the possibility of external leakage, and some occasion as: poisonous, inflammable, explosive, radioactivity etc. is arranged to safety, environment and healthy can working the mischief, be not allow external leakage to take place.China is at present general to adopt nonmetal membrane valve such as rubber, and it is simple in structure, seals singlely, only be suitable for the lower occasion of pressure and temperature, and working life is shorter, at HTHP and have under the situation of harsh conditions, can only rely on from foreign import.
Summary of the invention
The utility model technical problem to be solved: be to provide a kind of valve rod and spool branch are arranged, combine, be applicable to the novel instrument membrane valve of pressure, temperature, medium wider range with metal diaphragm and filler.
The technological scheme of the utility model is:
A kind of lower valve rod does not rotate the novel instrument membrane valve of four sealing configurations; Form by valve body, valve gap, lower valve rod, upper valve rod, time filler, last filler, screw thread guide pin bushing, spool etc.; It is characterized in that: the position that joins at the suitable for reading and valve gap of valve body is provided with a metal diaphragm; The top of metal diaphragm is a lower valve rod, and the below of metal diaphragm is a spool; One end of lower valve rod is provided with the end face that is sphere shape, and it is provided with circular cone in the other direction and the valve gap inner sealing surface is complementary, and the other end is the hole, and the bottom in hole is the plane, is uniformly distributed with 3～6 apertures on the relevant position of its circumference; The lower end surface of upper valve rod is a circular arc, is inserted in the hole of lower valve rod, and the circular arc end face is contacted with the base plane in hole, has both helped active force and has evenly distributed at the center of lower valve rod, helps the power of reducing friction again; All pack in each aperture steel ball of same size; Steel ball places in the arc groove of upper valve rod bottom simultaneously; Screw in upper valve rod simultaneously in the screw thread guide pin bushing together with lower valve rod and the steel ball that is contained in the aperture; Lower valve rod is coupled together through steel ball and upper valve rod actively, form the active linkage structure of steel ball; The two ends of following filler have following Packing seat to place valve gap inner respectively; Upper valve rod that installs and lower valve rod are passed valve gap and following filler and following Packing seat to appropriate location; Locknut is threaded to the thread root of screw thread guide pin bushing; Screw in the screw thread guide pin bushing in upper valve rod and the valve gap, make its end face compress down Packing seat and following filler; Form sealing by seal washer with metal diaphragm is fastening between valve gap and the valve body; Screw and regulate the screw thread guide pin bushing, make it promote down Packing seat and be pressed on filler down between lower valve rod and the valve gap, form packing seal structure down, the locknut locking of screwing; Be provided with packing seal structure in the upper end of screw thread guide pin bushing; To go up Packing seat, last filler and packing press ring places the screw thread guide pin bushing inner respectively in order; Screw and regulate the active force of gland nut, make on it and seal sealing configuration in the formation between the filler and upper valve rod and screw thread guide pin bushing; At the top of upper valve rod handle installation or handwheel, rotatable handle or handwheel drive the upper valve rod spiral lifting, under the effect of the active linkage structure of steel ball, make lower valve rod not rotate straight line motion up and down, promote the open and close that metal diaphragm and spool are carried out valve; The outside of spool is provided with spring and impels spool to go up and down to reset.
The advantage and the beneficial effect of the utility model are:
1, combined type valve gap design makes valve in various abominable applied environments, can both keep highly complete sealability and operating characteristics.
2, lower valve rod rotary lifting movement not in following filler, frictional force and fricting movement amount minimum, the sealability of valve is better, and the life-span is longer.
3, go up and to adopt the active linkage structure of steel ball between the lower valve rod, and steel ball rolls in the upper valve rod arc groove, improved motion antifriction degree, drop to the spin friction active force minimum, make the operation of valve free and relaxed.
4, because following packing seal in lower valve rod and valve inner position, completely cuts off with medium, help the lubricated influence that does not receive medium of all motive position such as screw thread and the active linkage structure of steel ball.
5, the worn-out sealing of screen of metal diaphragm and the back seal at twice packing seal structure and lower valve rod and valve gap position are up and down arranged, formed the quadruple sealing, quadruple is insured, sealability is more safe and reliable.
6, because the lower valve rod spherical end surface does not rotate, static promote the elevating movement of metal diaphragm spool, effectively protected metal diaphragm not rolled and wear and tear.
7, because last packing seal effect makes it with outside isolated, do not receive external environment influence.
8, prevent to become flexible behind the valve closing, be particularly suitable for being applied in the occasion of vibrations.
