Abstract
The utility model relates to an elastic slipper rotary plug valve, comprising a valve body 1, a plunger 2, an O-shaped sealing ring 3, a lock plate 4 and a top plate 5. Wherein the upper end of the plunger 2 is provided with the O-shaped sealing ring 3, the lock plate 4 and the top plate 5. The elastic slipper rotary plug valve is characterized in that the through path bore of the valve body 1 is column-shaped; the plunger 2 is column-shaped having the same size with the through bore of the valve body; the middle-lower part is provided with a lateral circular bore 10; two flat planes are milled at the 180 degrees symmetrical position of the column shape; a spring 6 is installed out of the flat plane; a sealing valve block 7 is installed out of the spring; a sealing plate 8 is embedded on the end surface of the sealing valve block 7; the plunger 2 is installed in the circular bore of the valve body and is fixed by the lock plate 4. The elastic slipper rotary plug valve is for opening or closing the liquid in pipeline systems, in particular to oilfield systems, chemical industry systems and gas pipeline systems whose pressure all smaller than 1. 6 M Pa.
Description
Technical field:
The utility model relates to a kind of elastic slide block stopcock.
Background technique:
Existing stopcock, form by valve body, stopper, O-ring seals, jam plate and top board, wherein, the port hole longitudinal section of valve body is generally trapezoidal, and stopper is a cone structure, and the upper end is provided with O-ring seals, jam plate and top board, for guaranteeing the sealing of medium, stopper tapering and valve channel hole need cooperate closely, and stopper and valve body need to grind mutually, and guarantee to be in contact with one another area greater than more than 80%.Difficulty of processing is big, sealability with reduce service time, the amount of reprocessing is big, working life short.
Summary of the invention:
The utility model provides a kind of elastic slide block stopcock, and wherein, stopper is cylindrical, and easily processing becomes Spielpassung to get final product with the valve body circular hole.This elastic slide block stopcock is made up of valve body, stopper, O-ring seals, jam plate and top board, and the stopper upper end is provided with O-ring seals, jam plate and top board, and it is characterized in that: the port hole of valve body is a cylindrical hole; Stopper is cylindrical, size is consistent with the valve channel hole, the middle and lower part has horizontal circular hole, mill into two flat planes in cylindrical 180 ° of symmetrical positions, outside its flat plane spring is housed, spring is equipped with the seal valve piece outward, studs with sealing plate on seal valve piece end face, stopper is placed in the valve body circular hole, fixes with jam plate.Jam plate is used for locking " opening " and " pass " state.
Elastic slide block stopcock and common stopcock difference are that stopper is cylindrical, and easily processing becomes Spielpassung to get final product with the valve body circular hole.It is also good more that stopcock increases sealability with line pressure.Long service life need not be reprocessed.
Description of drawings:
Fig. 1 is an elastic slide block stopcock structure schematic representation.
Fig. 2 is that stopper is formed schematic representation.
Embodiment:
See accompanying drawing 1～2, the utility model is a kind of elastic slide block stopcock, is made up of valve body 1, stopper 2, O-ring seals 3, jam plate 4 and top board 5, wherein, stopper 2 upper ends are provided with O-ring seals 3, jam plate 4 and top board 5, it is characterized in that: the port hole of valve body 1 is a cylindrical hole; Stopper 2 is cylindrical, size is consistent with the valve channel hole, the middle and lower part has horizontal circular hole 10, mill into two flat planes in cylindrical 180 ° of symmetrical positions, outside its flat plane spring 6 is housed, outside the spring 6 seal valve piece 7 is installed, on seal valve piece 7 end faces, stud with sealing plate 8, stopper 2 is placed in valve body 1 circular hole, and is fixing with jam plate 4.
Wherein, sealing plate is suppressed with raised line 9 in two ends about in the of 8.Spring 6 is the sheet spring.
This elastic slide block stopcock is applicable to the fluid that opens and closes pipe-line system, is specially adapted to use in the oil, chemical industry, gas pipeline system of pressure＜1.6MPa.
