Abstract
The utility model discloses a stop valve which comprises a valve body, a valve cap, a valve rod, a valve clack, a hand wheel, etc. The valve clack regarded as a closing member is designed into be connected with the spherical surface of the valve rod in a floating way, and a press cap connected with the valve clack is fitted with the clearance of the valve rod. Therefore, the valve clack can be automatically regulated in the operating process. The contact between the valve clack and a valve port is changed into slant contact from line contact, so defects, such as looseness, deflection, displacement, etc. can not be caused, the leakage preventing performance is increased and the service life of the valve is prolonged.
Description
The utility model relates to the valve arrangement of doing keying and throttling in the fluid piping system, the good stop valve of especially a kind of anti-leak performance.
Stop valve is keying and a throttle ele-ment of making medium in the fluid piping system, by widespread usage, common stop valve is made up of parts such as valve body, valve gap, valve rod, flap, handwheels, the flap that opens and closes valve port is that riveted is on valve rod, do that valve port opens and closes or the valve port opening size is done throttling and regulated with the lifting of valve rod, flap as closure member is that line contacts with the relation of valve port, after opening and closing operation several times, easily cause loosening, shift phenomenon, cause leak cutting and more than, therefore, report loss rate than higher in actual use.
The purpose of this utility model all provides a kind of anti-leak performance good stop valve in the defective that overcomes prior art.
Its design of the embodiment of above-mentioned purpose is: improve being connected of flap and valve rod emphatically, specifically comprise the valve body and the valve gap that are tightly connected, the valve gap top is sealed by gland nut and filler, be provided with the valve rod of making rotary lifting movement along valve gap in valve body and the valve gap, the valve rod upper end is provided with the handwheel that is in transmission connection with it, the lower end is provided with the flap that opens and closes the valve body valve port, it is characterized in that described flap is connected with the valve rod spherical floating, the pressure cap that connects flap cooperates with valve lever clearance, pressure cap is connected as rotation inhibiting by floor clip with flap, valve rod neck and pressure cap, be provided with the back-up ring of single face opening in the flap between the shoulder.
The utility model is connected with the valve rod spherical floating as the flap of closure member, and the pressure cap that connects flap cooperates with valve lever clearance, therefore, flap in the using process can be regulated automatically, be improved to the inclined-plane contact with contacting of valve port by the line contact, so can not cause defectives such as loosening, deflection, displacement, the anti-leak performance improves greatly, has prolonged the working life of valve.
Accompanying drawing 1 has provided structural representation of the present utility model.
Below by accompanying drawing embodiment the utility model is elaborated again.
As shown in Figure 1, stop valve has a valve body (14), and valve body has import, the outlet of medium circulation and the valve port that is opened and closed by closure member.Valve body is threaded with valve gap (8), and junction plane is provided with actinal surface packing ring (9) sealing.The top of valve gap is sealed by gland nut (5) and filler (7), and gland nut is threaded with valve gap, and filler between be provided with trim ring (6), screw gland nut and reach sealing purpose by the trim ring compressible filler.Be provided with the valve rod (4) of making rotary lifting movement along valve gap in valve body and the valve gap, thus valve rod and valve gap being threaded, be side, valve rod upper end tenon structure, handwheel (1) is in transmission connection with it, handwheel by nut (3) assembly tightly, label (2) also is fixed.The valve rod lower end is provided with the flap (13) that opens and closes the valve body valve port, flap male cone (strobilus masculinus) as closure member contacts with valve body valve port inclined-plane, be connected with the valve rod spherical floating again, the concrete solution that connects of floating is processing one groove on flap, the valve rod end face is an arc surface, be inlaid in the flap groove, the pressure cap (10) that is threaded with flap cooperates with valve lever clearance, and between pressure cap and flap, be provided with floor clip (11) and do anti-loosening the connection, be provided with the back-up ring (12) of single face opening in valve rod neck and pressure cap, the flap between the shoulder.
Open and close valve port and do throttling when regulating, rotation hand wheel drives valve rod and makes rotary lifting movement, the lifting of valve rod drives flap by back-up ring through pressure cap and do the adjusting of floating in lifting, until the flap male cone (strobilus masculinus) contact with valve body valve port inclined-plane close fully till, when doing the throttling adjusting, regulate the aperture size that flap leaves valve port on demand.
Claims (1)
1. stop valve, comprise the valve body (14) and the valve gap (8) that are tightly connected, the valve gap top is sealed by gland nut (5) and filler (7), be provided with the valve rod (4) of making rotary lifting movement along valve gap in valve body and the valve gap, the valve rod upper end is provided with the handwheel (1) that is in transmission connection with it, the lower end is provided with the flap (13) that opens and closes the valve body valve port, it is characterized in that described flap is connected with the valve rod spherical floating, the pressure cap (10) that connects flap cooperates with valve lever clearance, pressure cap is done anti-loosening the connection by floor clip (11), valve rod neck and pressure cap with flap, be provided with the back-up ring (12) of single face opening in the flap between the shoulder.
