Abstract
The utility model discloses a valve core type anti-leakage nozzle which can prevent the problem of unreliability of the nozzle. The valve core type anti-leakage nozzle comprises a nozzle head, a nozzle body, a valve core and an elastic component. The valve core is arranged in a structure which is composed by the nozzle head and the nozzle body, the elastic component is connected with the valve core, a first flow channel hole is arranged on the valve core, a second flow channel hole is arranged on the nozzle body, the first flow channel hole is connected with a nozzle opening, the second flow channel hole is connected with a fluid inlet, and the first flow channel hole is selectively communicated with the second flow channel hole by the elastic component. As the valve core type anti-leakage nozzle adopts the structure that the nozzle head is matched with inner and outer cylindrical surfaces of the valve core, the opening and closing of the nozzle are stable as well as reliable, and the leakage of the nozzle can be effectively prevented.
Description
Technical field
The utility model relates to a kind of nozzle, particularly a kind of valve core type leakproof nozzle.
Background technology
Existing needle valve nozzle since when closing spool and nozzle head be taper seat or linear sealing, can insecure problem appear closing owing to the fluctuation of mechanical precision or melt pressure.
The utility model content
The purpose of this utility model is to disclose a kind of valve core type leakproof nozzle, prevents that insecure problem from appearring closing in nozzle.
Valve core type leakproof nozzle described in the utility model, comprise nozzle head, nozzle body, spool and elastomeric element, spool is arranged in the structure of nozzle head and nozzle body formation, spool links to each other with elastomeric element, spool is provided with the first flow hole, and the nozzle body is provided with the second runner hole, and the first flow hole links to each other with the nozzle mouth, the second runner hole links to each other with fluid intake, and the first flow hole is selected to be communicated with by the elastomeric element and the second runner hole.
Wherein, elastomeric element can be spring.
Valve core type leakproof nozzle of the present utility model, owing to adopt the fit structure of the inside and outside circle cylinder of nozzle head and spool, the opening and closing of nozzle are reliable and stable, can effectively prevent the leakage of nozzle.
Description of drawings
Fig. 1 is the decomposition texture schematic diagram of the utility model valve core type leakproof nozzle.
Mark the following drawings mark thereon in conjunction with the accompanying drawings:
1-nozzle head, 2-nozzle body, 3-spool, 4-spring, 5-first flow hole, the 6-second runner hole, 7-fluid intake, 8-nozzle mouth.
The specific embodiment
Below in conjunction with accompanying drawing, a specific embodiment of the present utility model is described in detail, but is to be understood that protection domain of the present utility model is not subjected to the restriction of the specific embodiment.
As shown in Figure 1, the utility model valve core type leakproof nozzle comprises nozzle head 1, nozzle body 2, spool 3 and spring 4, nozzle body 2 and nozzle head 1 are integral according to the water (flow) direction setting-in, spool 3 is arranged in nozzle head 1 and the nozzle body 2, spool 3 links to each other with spring 4, spool 3 is provided with first flow hole 5, nozzle body 2 is provided with the second runner hole 6, first flow hole 5 links to each other with nozzle mouth 8, the second runner hole 6 links to each other with fluid intake 7, when the pressure that enters nozzle from fluid intake 7 when fluid was lower than the pressure of spring 4, spool 3 was in the right side in the nozzle body 2 under the effect of spring 4, made the stagger distance of L of the first flow hole 5 and the second runner hole about 6, as shown in Figure 1, valve core type leakproof nozzle is in closed condition, and wherein, nozzle head 1 and spool 3 all are cylindrical structure.
When the pressure of fluid during greater than the pressure of spring 4, under the effect of fluid pressure, spool 3 is pushed to the left side in the nozzle body 2, and first flow hole 5 is communicated with the second runner hole 6, and valve core type leakproof nozzle is in opening, and fluid is flowed out nozzle.
Valve core type leakproof nozzle of the present utility model, owing to adopt the fit structure of the inside and outside circle cylinder of nozzle head and spool, the opening and closing of nozzle are reliable and stable, can effectively prevent the leakage of nozzle, and the pressure of spring can be adjusted according to the size of required fluid opening pressure.
More than disclosed only be a specific embodiment of the present utility model, still, the utility model is not limited thereto, any those skilled in the art can think variation all should fall into protection domain of the present utility model.
