Description
The utility model belongs to a kind of control valve in the mechanical industry fluid mechanics system, specially refers to a kind of pressure controlled valve, is applicable to the accurate pressure regulation of petrochemical industry high-pressure system.
Prior art Chinese patent (91204818.2) " pressure controlled valve ", the import and export direction of this valve are for vertical mutually, in its pipeline configuration, usually not as convenient on same direction.And its spring shield is unfavorable for effective utilization of metal by the processing of block of metal car system.The more important thing is: this valve is when control system pressure is higher, and the counter-force of pressure adjusting spring is big, the surface friction drag of region of interest is increased, thereby it is not smooth to cause handwheel to rotate, the operation effort.
The purpose of this utility model: be in order to overcome the shortcoming of above-mentioned pressure controlled valve, and a kind of novel pressure controlled valve is provided, more be applicable to the accurate pressure regulation of high-pressure system.Have compact structure, highly sensitive, good airproof performance, processing and easy to maintenance, save material, lower-cost characteristics such as easy to implement.
In order to realize this purpose, invention scheme of the present utility model is: the structural representation that provides a kind of pressure controlled valve in Figure of description.It is mainly by inlet attack (1), valve body (2), plastics flap (3) and (30), O RunddichtringO (4), (14), (20) and (29), following pressure block (5), locking nut (6), screw rod (7), handwheel (8), screw (9), last pressure block (10), pressure adjusting spring (11), spring shield (12), guiding valve (13), valve core spring seat (15), spring (16), spool screwed pipe (17), spool (18), spool pad (19), valve seat (21), screw (22), handwheel cover (the decals board is used) (23), nut (24), pad (25), circumferential ring expander (26), part such as bearing housing (27) and thrust bearing (28) is formed.It is characterized in that the realization that is used for by O RunddichtringO (20), valve seat (21) and screw (22), both lateral sides in valve body (2) is opened in the inlet/outlet joint screw thread hole of valve, make the tapped hole central axis all vertical with valve body (2) central axis, and in same plane, this is being on the same substantially horizontal into and out of oral pore valve body (2) just.The hole seat that makes screw communicates respectively by two cavitys that separated by valve seat (21) in aperture and the valve body (2).Spring shield (12) is a tubular structure, adopts suitable standard tubing processing, can save metallic material.Adopted the structure of thrust bearing (28), thereby the pivoting friction of its surface of contact is reduced, and adopted the bigger handwheel of moment (8), made it rotate light piece.About concrete feature and the embodiment in the Figure of description, in the Figure of description explanation, described.
Advantage of the present utility model:
A kind of pressure controlled valve is applicable to the accurate pressure regulation of petrochemical industry high-pressure system.This valve be to be on the same substantially horizontal into and out of oral pore, make pipeline configuration convenient, adopted thrust bearing (28) structure, thereby the pivoting friction of its surface of contact reduced, and adopted the bigger handwheel of moment (8), make it rotate light piece, rapid operation.Spring shield (12) is a tubular structure, can adopt the processing of standard tubing.Therefore, this valve have rational in infrastructure, compact, highly sensitive, good airproof performance, processing and easy to maintenance, save material, cost is lower and characteristics such as easy to implement.
Below in conjunction with Figure of description, concrete feature of the present utility model and embodiment are further described:
The utility model Figure of description is mainly by inlet attack (1), valve body (2), plastics flap (3) and (30), O RunddichtringO (4), (14), (20) and (29), following pressure block (5), locking nut (6), screw rod (7), handwheel (8), screw (9), last pressure block (10), pressure adjusting spring (11), spring shield (12), guiding valve (13), valve core spring seat (15), spring (16), spool screwed pipe (17), spool (18), spool pad (19), valve seat (21), screw (22), handwheel cover (the decals board is used) (23), nut (24), pad (25), circumferential ring expander (26), part such as bearing housing (27) and thrust bearing (28) is formed.Concrete enforcement is that thrust bearing (28) is to be limited in the spring shield tube (12) by bearing housing (27) and circumferential ring expander (26) by handwheel (8), nut (24), pad (25) and fastening the linking of screw rod (7).Last pressure block (10) is to be pressed on the pressure adjusting spring (11), and the screw (9) that connects with last pressure block (10) by screw thread extend in the slotted hole of spring shield (12), plays restriction and goes up the effect that pressure block (10) rotates.Screw rod (7) all the time by pressure adjusting spring (11) by through last pressure block (10) roof pressure of scyewed joint on thrust bearing (28), thrust bearing (28) is limited in the spring shield (12) by bearing housing (27) and circumferential ring expander (26).When the left and right rotation of screw rod (7), pressure block (10) go up to be slided, compress for pressure adjusting spring (11) or loosen realizing, thereby obtain increase that needs or the spring pressure that reduces.Spring shield (12) be by screw threads for fastening on valve body (2).Pressure adjusting spring (11) is to be pressed on down on the pressure block (5), and the center of the internal surface of following pressure block (5) contacts with guiding valve (13) central upper portion high spot.Valve seat (21) be by screw (22) by limit in the cavity of resorption of valve body (2), valve seat (21) places the cylinder hole between the upper and lower chamber of valve body (2), by the O RunddichtringO (20) that is embedded on the guiding valve (13) upper and lower cavity is separated.Plastics flap (3) and (30) are to use capping into and out of oral pore, in case foul enters.When locking nut (6) is installation, use during fixed valve body (2), valve body (2) is all used O RunddichtringO (4) and (29) sealing with the point of attachment of inlet/outlet joint.Handwheel cover (23) is that the decals board is used.Valve body (2), guiding valve (13) and valve seat (21) are to adopt copper material or stainless steel material to make.O RunddichtringO (4), (14), (20) and (29) are to adopt oil resistant rubber, fluorine rubber or silicone rubber material to make, and require to select for use according to used working medium.
