Abstract
The utility model relates to an anti-drip leakage nozzle, which comprises a jet tube and a main nozzle body; wherein, an one-way pressure valve is also arranged between the jet tube and the main nozzle body; the one-way pressure valve comprises a spring, a ball and a fixing cap which are arranged in order; the fixing cap is screwed in the water inlet of the nozzle and limits the spring and the ball in the water inlet; the fixing cap is provided with a water inlet hole which is communicated with the water inlet; the size of the water inlet hole is matched with that of the ball; and the one-way pressure valve can prevent the liquid in the jet tube from dripping.
Description
Technical field
The utility model relates to a kind of nozzle, specifically is a kind of antidrip nozzle.
Background technology
Nozzle is daily life parts commonly used, be mainly used in aspects such as plant protection, cleaning, present nozzle is the ubiquity weeping under the low pressure situation, such as equipment for plant protection when quitting work, solution in the jet rod also can constantly drip from nozzle, not only waste solution, also may damage human body; Also have such as automatic car washing machine, finish at each carwash, high-pressure pump quits work suddenly, the cleaning fluid of jet rod can constantly drip in nozzle, because jet rod is longer, the cleaning fluid in the pipe is more, the situation of nozzle drippage is not only wasted cleaning fluid, also can improve the cost of cleaning greatly simultaneously.
The utility model content
The purpose of this utility model is to provide a kind of antidrip nozzle, be provided with pressure check valve at this nozzle in import department, when the injection inner pipe water pressure was lower than the pressure of pressure check valve setting, pressure check valve was kept apart playpipe and nozzle, played the effect that prevents the liquid water clock in the playpipe.
The utility model is achieved in that
A kind of antidrip nozzle comprises playpipe and nozzle body, it is characterized in that: be provided with also pressure check valve between described playpipe and nozzle body.
Described pressure check valve is made up of spring, ball and locking cap, the three is arranged in order setting, locking cap is screwed in the water inlet of nozzle and spring and ball is limited in the water inlet, have the inlet opening that communicates with water inlet on locking cap, the size of inlet opening matches with the size of ball.
The utility model is provided with pressure check valve in the water inlet of nozzle, when working at ordinary times, the liquid of playpipe inner high voltage can back down the ball of pressure check valve easily, make the high pressure liquid physical efficiency spray from nozzle, when needs stop to spray when hitting, liquid in the playpipe does not have the effect of external force to be in low-pressure state, this moment, the spring of pressure check valve can horse push up ball to locking cap, inlet opening sealing with locking cap, the passage of blocking-up playpipe and nozzle, thereby make the liquid in the playpipe be unlikely to, cause waste and some unnecessary troubles from the nozzle water clock.
Description of drawings
Fig. 1, structural representation of the present utility model.
The specific embodiment
As shown in Figure 1, a kind of antidrip nozzle, comprise playpipe 1 and nozzle body 2, between described playpipe 1 and nozzle body 2, be provided with also pressure check valve, described pressure check valve is made up of spring 31, ball 32 and locking cap 33, the three is arranged in order setting, locking cap 33 is screwed in the water inlet of nozzle body 2 and spring 31 and ball 32 is limited in the water inlet 21, have the inlet opening 34 that communicates with water inlet 21 on locking cap 33, the size of inlet opening 34 matches with the size of ball 32.
The utility model mainly is provided with pressure check valve between nozzle body and playpipe, in the present embodiment, pressure check valve adopts Embedded pressure check valve, whole pressure check valve is arranged on the water inlet of nozzle body, by pressure check valve passage between playpipe and the nozzle body is isolated, when playpipe is in high pressure conditions, the liquid of playpipe or solution can back down the ball of pressure check valve easily, this moment, nozzle body and playpipe were in conducting state by the inlet opening of locking cap, but nozzle body operate as normal, and be in low-pressure state and pressure and be lower than the pressure check valve setting value and be when spraying liquid in pipe, this moment, the ball of pressure check valve sealed the inlet opening of locking cap in the effect of spring, the interior liquid of playpipe just can't flow in the nozzle body, thereby plays drip-proof effect.
Claims (2)
1, a kind of antidrip nozzle comprises playpipe and nozzle body, it is characterized in that: be provided with also pressure check valve between described playpipe and nozzle body.
2, a kind of antidrip nozzle as claimed in claim 1, it is characterized in that: described pressure check valve is made up of spring, ball and locking cap, the three is arranged in order setting, locking cap is screwed in the water inlet of nozzle and spring and ball is limited in the water inlet, have the inlet opening that communicates with water inlet on locking cap, the size of inlet opening matches with the size of ball.
