Description
Technical field:
The utility model relates to sample cock, particularly oil field hydraulic fluid port anti-theft sampling valve.
Background technology:
Existing oil field hydraulic fluid port sample cock contains valve body, valve rod, spool, stem bearing and hand wheel, and stem bearing is fixed on the valve body, valve rod and stem bearing threaded engagement, and spool is fixed on the valve rod, and the hand wheel sky is enclosed within on the valve stem tip.The slewing maneuver handwheel drives the relative stem bearing of valve rod and moves up and down, thus the opening and closing action of spool on the realization valve rod and the oil through on the valve body.Because without any anti-theft device, therefore, the thief just can steal oil easily in a large number by sample cock, has caused tremendous loss to the oil field on the hydraulic fluid port sample cock of existing oil field.
The utility model content:
The purpose of this utility model is to provide a kind of theftproof performance reliable anti-theft sampling valve.
Solution of the present utility model is: contain valve body, valve rod, spool, stem bearing and hand wheel, stem bearing is fixed on the valve body, valve rod is axially fixed on the stem bearing, the spool that moves up and down of stem bearing cooperates with the valve rod end thread relatively, ratchet is fixedly mounted on the valve rod, with can do the contacted elastic pawl of axially movable lock core be arranged on ratchet on the corresponding position of ratchet on, the hand wheel sky is enclosed within on the valve stem tip.
The connectivity port is arranged on the valve body, and stem bearing is fixed on the connectivity port.
Lock core is stuck in the inner chamber of lock body by lock tube, and lock tube is fixedlyed connected with lock body, and lock body is fixed on the adapter sleeve, and adapter sleeve is fixed on the connectivity port on the valve body.
Lock core is against on the ratchet, between ratchet and the lock body back-moving spring has been installed, and ratchet cooperates with lock body is movable.
Be provided with chute on the outer side edges of spool vertically, the stem bearing inner chamber has been installed slide block, and slide block and chute are slidingly matched.
Slide block and chute all are symmetrical arranged.
Establish the shoulder lattice on the valve rod, the shoulder lattice are against on the side of stem bearing, and the valve rod pressure cap is fixed on the stem bearing and is stuck on the shoulder lattice.
The oil resistant cushion rubber is installed between valve rod and the stem bearing.
After adopting the utility model, Open valve must use key to open lock core, makes the lock core segment distance of drawing back, and ratchet disengages with ratchet on the ratchet under the effect of back-moving spring, and valve rod can rotate poppe tvalve core under the driving of hand wheel; Simultaneously, change valve rod into blind rod type by traditional rising stem (RS.) formula, during Open valve, hand wheel is enclosed within on the valve rod can light rotation valve rod, poppe tvalve core, after work is finished, the hand wheel taking-up is taken away, made the thief not have special-purpose hand wheel to be difficult to rotation valve rod, play the effect of dual fail-safe, theftproof performance is good, and compact conformation is easy to maintenance.Lockset adopts stealthy the installation, is not directly exposed in the atmospheric environment, and the installation of also can standing upside down keeps away lockset water inlet on rainy day, corrosion, has prolonged application life.
