Abstract
The utility model discloses an expansion valve with a valve body in clearance fit with a valve seat, wherein the valve includes the valve body (1), the valve seat (2) and a valve plate (3), the valve seat (2) is mounted in the valve body (1), and the valve plate (3) is combined on the valve seat (2).The valve is characterized in that the valve seat (2) consists of a valve seat body (4), a seal ring (6) and an O-shaped ring (8); a teeth-shaped groove (5) is arranged at the front end of the valve seat body (4); a seal ring (6) is mounted in the teeth-shaped groove (5); a V-shaped groove (7) is arranged at the rear end of the valve seat body (4); and the O-shaped ring (8) is inserted into the V-shaped groove (7) to integrally form the valve seat. The expansion valve with the valve body in clearance fit with the valve seat has a simplified structure, is easy to mount and dismount, is convenient to maintain, reduces the manufacture cost, improves the sealing safety, and prolongs the service life.
Description
Technical field
The utility model relates to expansion valve, be specifically related to a kind of valve body and valve seat movingly expansion valve.
Background technique
At present, the expansion valve that use in known oil field, be the interference drive fit between its valve seat and the valve body, valve rod rises and descends simultaneously, driving valve plate inside " V " piece moves and expands and do corresponding opening and closing, this valve plate expands and directly acts on and valve seat, and is extremely inconvenient to assembling valve seat and M R.
Summary of the invention
The purpose of this utility model is: a kind of valve body and valve seat expansion valve movingly is provided, and simplified structure, the mounting or dismounting ease of connection maintains easily maintenance, reduces manufacture cost, improves the sealing safety, prolongs the working life of valve.
Technical solution of the present utility model is: this valve comprises valve body, valve seat and valve plate, valve seat is installed in the valve body, cooperate valve plate on the valve seat, it is characterized in that: valve seat is made up of valve body, seal ring and " O " type circle, establish at the front end of valve body and to nibble connected in star, nibble seal ring is installed in the connected in star, establish " V " shape groove in the rear end of valve body, " V " shape groove is embedded in installation " O " type circle, whole formation valve seat.
Valve plate is perpendicular to flow direction, directly act on valve seat by the valve plate expansive force and make the valve seat move left and right, the radial dimension quantitative change according to the certain pretightening force of " O " type circle, takes place and moves in " O " type circle generation resiliently deformable trace change of establishing between valve seat and the valve body after " V " groove limits.
The utlity model has following advantage: 1, simple in structure, valve body and valve seat are for movingly, alleviating valve body and valve seat interference drive fit when assembling is pressed into valve seat with press machine and produces distortion and phenomenon is scrapped in damage, reduces the difficulty that changes of valve seat assembly deflections, improves working life greatly; 2, valve plate is perpendicular to flow direction, make the valve seat move left and right by the direct effect of valve plate expansive force with valve seat, " O " type circle generation resiliently deformable trace change of establishing between valve seat and the valve body, according to the certain pretightening force of " O " type circle, the quantitative change of generation radial dimension is moved and is reached sealing effect after " V " groove limits, be two-way soft seal between valve body and the valve seat, produce excellent sealing performance.
