Description

Rod water snout

The utility model relates to a kind of novel Draw off valve is water tap.

Usually the water tap of the usefulness water that mainly contains stop valve formula screw rod poppet is chewed, and cock-type water is chewed and ball-valve type water such as chews at the product of form.It is secondary easy to wear and water is chewed leak and lost efficacy that stop valve formula water is chewed its lift-bolt of main existence, but is difficult for the defect of repairing; The cock synetion that cock-type water is chewed relatively rotates that amplitude is big, and the wearing and tearing of generation are also very big, and the axially locating poor performance of cock, thereby also is easy to produce and leaks and lost efficacy, and also is difficult to repair; It is similar that ball-valve type water is chewed the situation of chewing with cock water.And the valve rod chewed of above-mentioned several water all must be by circumference rotation startup valve, so and the wear extent between the valve rod sealing member all very big, often be difficult to better seal, make inconvenient operation.Simultaneously, the manufacturing process performance that above-mentioned several water are chewed is also relatively poor, so their practicability and Economy are all not ideal enough.

The purpose of this utility model is exactly the situation of chewing at above-mentioned water and a kind of new-type water that designs chewed, and it is good to have performance, and long service life is easy to repair, and easy to operate, simple in structure, the manufacturing process characteristic of simple.

Solution of the present utility model is: the stem lower portion in valve body is equipped with lower seal and last seal ring, at the valve rod middle part composite sealing ring is housed, promptly in the groove in seal ring a seal ring is housed again, and the internal surface of seal ring and valve body is a drive fit, the top of valve rod is connected with handle, handle is a cam-like, cooperate with valve rod, have the curvilinear groove parallel on the handle with its cam external frame, pin passes curvilinear groove and is connected with valve rod, handle is hinged on again on the support that is connected as a single entity with valve body, and its detailed content is described below referring to accompanying drawing:

Referring to Fig. 1, Fig. 2, straight-bar type water of the present utility model is chewed, lower seal (9) and last seal ring (8) are equipped with in the bottom that it is characterized in that the valve rod (7) in valve body (10), lower seal (9) is used for the water inlet of sealed valve body (10), make this water chew that water can not flow out under closing state, at the middle part of valve rod (7) composite sealing ring (5) is housed, (6), promptly in the groove in seal ring (5) seal ring (6) is housed again, and the internal surface drive fit of seal ring (5) and valve body (10), when this water is chewed when being in opening state, seal ring (5) and (6) avoid water upwards to flow out along valve body (10) internal chamber wall especially valve rod (7), guarantee that sealing is reliable, chew when being opened to maximum position when water, last seal ring (8) tightly fits together with seal ring (5), has increased by a cover sealing again.The top of valve rod (7) is connected with handle (1), handle (1) is a cam-like, cooperate with valve rod (7), thereby actuate valve stem (7) motion, have the curvilinear groove parallel on the handle (1) with its cam external frame, constitute another cam structure, pin (3) passes curvilinear groove and is connected with valve rod (7), and handle (1) is movably articulated in again on the support (4) that is connected as a single entity with valve body (10).During use, will lift on the handle (1), the cam of handle (1) discharges valve rod (7) on the one hand, drives valve rod (7) by curvilinear groove on it and pin (3) on the other hand and moves upward, and water is chewed and opened, and water flows out from the outlet of valve body (10).When lifting to the extreme higher position on the handle (1), water is chewed inner hydraulic pressure and is in maximum, last seal ring (8) on the valve rod (7) tightly is fitted on the seal ring (5), increased sealing together again for valve rod (7), make valve rod (7) sealing be in good state all the time, simultaneously buffer function has been played in the motion of valve rod (7).Handle (1) can be pulled any height as required, with the control waterdrainage amount, because of the cam of handle (1) and on curvilinear groove the effect of valve rod (7) is remained self-locking state.Close water when chewing, the cam drive valve rod (7) of handle (1) moves downward, valve rod (7) cone-shaped bulge bottom enters in the water intake of valve body (10), works to make valve rod (7) location, by lower seal (9) water is chewed and is in good closed condition.

Feature of the present utility model also be the linkage structure of valve body (10) and support (4) be the bottom of support (4) be contained in seal ring (5) in the valve body (10) above, have cone shape hole on its circumference, going up the corresponding screw that is lower than conical bore that has with the valve body (10) of cone shape hole corresponding part, lock screw (12) links together valve body (10) and support (4), after lock screw (12) is tightened, the conical surface of screw (12) head is pressed on the inclined-plane of conical bore of support (4), utilize wedge surface to press tighter and tighter, thereby seal ring (5) and valve body (10) are more closely combined, improved sealing.Part of the present utility model is manufactured by materials such as cast iron, shaped steel and rubber.

The straight-bar type water that the utility model provides is chewed the sealability of chewing than traditional water and is improved greatly, because valve rod is a polished rod, do not do the circumference rotation and be provided with multi-layer sealed circle again, so the sealing at valve rod place improves more than six times, and is simultaneously, simple in structure, the manufacturing process performance is superior, use easy to operately, and very be convenient to maintenance, have good practicability and Economy.

Accompanying drawing has been represented specific embodiments of the present utility model.
