Abstract

The utility model relates to a valve whose structure includes a valve body. The center of the valve body is a cylindrical cavity. Two ends of the cavity body are a water inlet and a water outlet. A cylindrical valve core vertical to the water inlet and the water outlet is arranged in the cavity body. A radial through hole corresponding to the positions of the water inlet and the water outlet is arranged in the valve core. A rotating handle is arranged on the upper end of the valve core. The valve core is tightly matched with the cavity body in a rotating way. In order to maintain the tight leak-proof quality between the valve core and the cavity body, a slot is grooved in the middle of the cavity body, and a sealing ring is arranged in the slot. In addition, a stopper ring is arranged in the slot of the middle of the cavity body to prevent the valve core from being drawn out of the cavity body carelessly when in use. A stopper slice which is higher than the lower edge of the handle is arranged at the cavity body port of the upper end of the valve body to prevent from turning out of the position when the handle is turned. The utility model has the advantages of simple structure, high sealing, easy installation and operation, long service life and low producing cost, and being especially suitable for family use.

Description

A kind of valve

Technical field

The utility model relates to a kind of valve, particularly is applicable to the civilian valvelet of getting water supply installation.

Background technique

Get in the water supply installation civilian, between the pipeline, be connected between pipeline and the device and will use valve, in the service water heating equipment, valve is indispensable parts equally.The valve of Shi Yonging has spherical valve, gate valve etc. in the prior art, and the spool of valve is generally metallic material, as copper, cast iron etc., is used for commercial device, and the shortcoming of existence is that cost is higher.It is injection molded that also some valve adopts engineering plastics, but spool still adopts the metallic material manufacturing, though cost is lower, the technological deficiency that exists is because of spool expands with valve body, shrinkage coefficient is different, be difficult to guarantee the sealing of spool and cavity, influenced it and applied.

Summary of the invention

The purpose of this utility model is to provide a kind of suitable family to use, and the life-span is long, and cost is lower, the valve of reliable performance.

Realize that the technological scheme that the purpose of this utility model is taked is such: a kind of valve, comprise valve body in the structure, the valve body middle part is a circular cylindrical cavity, the cavity two ends are respectively water intake and water outlet, in cavity, be provided with cylindrical spool perpendicular to water intake and water outlet, have radial direction through hole corresponding to water intake and water outlet position on spool, there is the hand of rotation valve the spool upper end, and spool and cavity pivoting friction closely cooperate.

Keep sealing closely between spool and the cavity for making, have groove, be equiped with seal ring in the groove at the cavity middle part; In addition, in the groove at cavity middle part, be equiped with baffle ring, can prevent from accidentally spool to be extracted cavity in the using process.

Be provided with the catch that exceeds the handle lower limb in cavity port, valve body upper end, can avoid when screwing handle, twisting the position.Catch length can guarantee the lucky half-twist of spool near 1/4 valve body circumference, makes the complete folding of valve.

This valve water intake and water outlet and extraneous Placement can have multiple, both can adopt and be threaded, also can adopt the grafting form, as long as inlet end, water outlet end are processed into the interface of screw mouth or band vertebra degree and draw-in groove structure, ordinary circumstance is: an end is a screw mouth, the other end is the interface of band vertebra degree and draw-in groove structure, so that and external water pipe grafting.

Valve of the present utility model engineering plastics manufacturing, valve body adopts Shooting Technique, and spool is injection molded into blank earlier, forms through machining again, so not only can guarantee the mechanical seal of spool and cavity, can also enhance productivity.

The technique effect that the utility model is obtained is: it is simple in structure, the sealing height, and easy to install, working life is longer, and with low cost.

Description of drawings

Fig. 1 is an outline drawing of the present utility model.

Fig. 2 is structural representation of the present utility model (cuts open and show).

Each label is represented following implication among the figure:

1, handle 2, catch 3, valve body 4, water intake 5, water outlet 6, pressure cap 7, screw 8, baffle ring 9, seal ring 10, spool 11, through hole.

Embodiment

Below in conjunction with accompanying drawing the utility model is described further.

See Fig. 1 and Fig. 2, a kind of valve, comprise the valve body 3 that is injection molded into the high density polyethylene (HDPE) engineering plastics in the structure, valve body 3 middle parts are circular cylindrical cavity, cavity one end is a water intake 4, and port cooperates for the interface and the external water pipe grafting of band vertebra degree and draw-in groove structure, the other end water outlet 5 has outside thread, is threaded with the water device.In cavity, be provided with the cylindrical spool 10 that is processed into the high density polyethylene (HDPE) engineering plastics perpendicular to water intake and water outlet, on spool 10, have radial direction through hole 11 corresponding to water intake and water outlet position, the upper end of spool 10 is fastenedly connected by screw 7 and rotation hand valve 1, the top is pivoting friction with cavity and closely cooperates with pressure cap 6 shutoff, spool 10.Keep sealing closely between spool 10 and the cavity for making, have groove at the cavity middle part, being equiped with rubber seal 9 in the groove seals, also be equiped with plastics baffle ring 8 in the groove, be sleeved on spool 10 outsides and be stuck in the groove, to prevent accidentally spool 10 to be extracted cavity in the using process.See Fig. 1, be provided with the catch 2 that exceeds handle 1 lower limb in cavity port, valve cavity upper end, to avoid when screwing handle, the twisting position.Catch length can guarantee the lucky half-twist of spool near 1/4 valve body circumference, makes the complete folding of valve.This valve is particularly suitable for family and uses.

Claims (4)
