Abstract
The utility model belongs to the technical field of control valves, in particular to a direct pressure type valve seat of a control valve with high performance. The valve seat is characterized in that a valve seat (4) is designed into the direct pressure type; a valve core (3) and a valve rod (1) form an additionally-arranged integrated low noise sleeve (5); the lower end of a valve rod (1) is embedded into the axle center of the valve core (3); the valve core 3 nested on the valve rod (1) shown on the Figure 1 is positioned at the bottom inside an upper valve chamber; the valve seat (4) is arranged between the upper valve chamber and a lower valve chamber; and a direct pressure type valve seat (4) with available double surfaces is arranged between the upper and the lower valve chambers, and the lower part of the valve core (3) is embedded in the direct pressure type valve seat (4) with available double surfaces. A guide sleeve (2) is arranged at the upper part of the valve rod (1); and a low noise sleeve (5) is nested outside the valve rod (1) and the valve core (3). Small holes are distributed on the periphery of the low noise sleeve (5) and have the pressure balancing action, so that the upper surface and the lower surface of the novel direct pressure type valve seat with available double surfaces are available. The utility model has the advantages that the upper and the lower surfaces of the direct pressure type valve seat with available double surfaces are available, and the service life of the valve is prolonged; the valve seat can be installed and removed quickly without special tools, and the maintenance cost is low; no leakage problem is caused between the valve seat and the casing, and the shape of the valve seat is simple and symmetrical; and different materials can be chosen to be processed according to different working conditions, and the valve seat can be aligned and sealed, and meet the leakage levels of ANSIB 16.1 (Level IV to Level V).
Description
[technical field]
The utility model belongs to the control valve technical field, particularly is a kind of direct press type valve seat of high performance control valve.
[background technique]
Tradition control valve seat design is that valve seat adopts screw thread to be connected with valve body, needs with special instrument dismounting, and assembling and maintenance cost are big.The tradition valve seat can only use by single face, and working life is short.Because the flange deep hole is all wanted special machining screw in valve seat and the valve body, machining error certainly will be arranged, cause valve seat to be installed less than correct central position, the sealing grade reduces, and a lot of for guaranteeing to seal the milling time and the material that are spent, leakage class ANSIB16.104 IV level.
[summary of the invention]
The purpose of this utility model is to overcome existing traditional control valve seat design, a kind of novel direct press type valve seat of design.Comprise: valve rod 1 guide sleeve 2 spools 3 valve seats 4 sleeves 5 valve bodies 6.It is characterized in that valve seat 4 design direct press types, spool 3 is formed the integrated low noise sleeve 5 that adds with valve rod 1, embed spool 3 axle center in valve rod 1 lower end, the spool 3 that is set on Fig. 1 valve rod (1) is positioned at the valve chamber inner bottom part, be provided with valve seat 4 between the upper and lower valve chamber, establish two-sided available direct press type valve seat 4 between the upper and lower valve chamber, spool 3 bottoms embed in the two-sided available direct press type valve seat 4.Guide sleeve 2 is arranged at described valve rod 1 top, is positioned at valve rod 1 spool 3 outer sheathed low noise sleeves 5.Described low noise sleeve 5 whole body are evenly equipped with aperture.Has the pressure balance effect.But direct press type valve seat upper and lower surface uses.Improve working life and need not adopt special tool(s) to install rapidly and to remove, reduce maintenance expenses, and the leakage problem between valve seat and the housing can not occur, simple shape, symmetry can select for use not same material to process according to different operating modes.
The utility model beneficial effect: but novel two-sided available direct press type valve seat upper and lower surface uses.Improve valve working life, need not adopt special tool(s) to install rapidly and to remove, reduce maintenance expenses, leakage problem between valve seat and the housing can not appear, simple shape, symmetry, can select for use not same material to process according to different operating modes, from centering sealing, leakage class ANSIB16.104IV ~ V level.
