Abstract
The utility model relates to an antifreezing switch device for running water, which is composed of a valve body, a valve core, a lengthening handle, etc. The utility model is characterized in that the valve core which is a spherical valve core is provided with a center through hole; the valve body forms a four-way shape, and the valve body and the spherical valve core are connected through a path which is provided with a sealing gasket; the spherical valve core is provided with a slot which is connected with the lengthening handle through a shifting block and a pin; the lengthening handle is screwed for opening and closing the running water. When the running water is not used, water is not stored in a water tap and in an exposed water pipe for ensuring that the utility model can be normally used outdoors in cold winter.
Description
The utility model relates to a kind of tap water anti-freezing switch gear.
Northern China winter climate cold, outdoor running water pipe and the easy bursting by freezing of water tap, for guarantee cold winter the open air water tap can normally use, existing patent application CN2088183U has announced a kind of tap water anti-freezing valve, it is that frost valve is arranged in the melt pit, and turn the spool unlatching and close tap water to add long handle, when closing tap water, the water in water tap and the water pipe is discharged in case the water stopping tube bursting by freezing automatically by spool.Analyze its valve core structure as can be known, it is cylindrical valve spool or taper valve core, or other shape spool, but spherical valve core forecloses.Because spherical valve core can't be loaded into, moreover no sealing gasket also can not be realized sealing between spherical valve core and the valve body.And it is serious to adopt cylindrical valve spool to leak, and taper valve core seals on the valve seat by being pressed on, and impacting force is little then leaks seriously, and impacting force greatly then spool is twisted motionless.
It is more reliable that the purpose of this utility model provides a kind of sealing, operates tap water anti-freezing switch gear easily.
Technical solution of the present utility model is: above-mentioned tap water anti-freezing valve is done one change, be about to its spool and make spherical valve core into, spherical valve core has center hole, and correspondingly, valve body changes into has four-way.Stir spool to realize the open and close tap water with a shifting block, close, open leakage water simultaneously.Sealing is realized by sealing gasket in passage connecting part at spool and valve body.
The utility model comes well more, reliable than above-mentioned cylindricality or cone seal, and spool turns easily.Because can't compensate after the cylindrical valve spool wearing and tearing; Though taper valve core wearing and tearing back can compensate, but it provides sealing by spool is pressed on the valve seat, it is just bad that this valve is worked as the impacting force hour sealing that is applied on the spool, and impacting force one is big, valve core rotation is just dumb, the utility model has overcome the shortcoming of existing utility model application, provides a kind of sealing reliable, turns tap water anti-freezing switch gear flexibly.
The utility model is embodiment be illustrated in conjunction with the accompanying drawings.
Fig. 1 is the utility model working position schematic representation;
Fig. 2 is the utility model sectional view;
Fig. 3 is an A-A sectional view among Fig. 2.
As shown in the figure, (1) water tap, (2) add long handle, (3) melt pit, (4) tap water water inlet, (5) valve body, (6) are the ditch down, (7) running water pipe, (8) bayonet lock, (9) sleeve, (10) pin, (11) seal bowl, (12) shifting block, (13) water inlet head, (14) sealing gasket, (15) spherical valve core, (16) valve body, (17) drainage gallery, (18) sluicing sealing gasket, (19) plug.
As shown in Figure 1, the utility model is placed in the melt pit with antifreeze, turning the lengthening driving lever makes it in the enable possition, water tap (1) has been located tap water and has been flowed out, cycle lengthening driving lever makes it in closed position, the water source cuts off from the beginning, and the water in water tap (1) pipe flows to down the ditch through valve body and spool simultaneously.
As shown in Figures 2 and 3, valve body (16) is the four-way shape, and there is a spherical valve core (15) at valve body (16) middle part, and spherical valve core (15) all has sealing gasket to be connected with each interchannel of valve body, and spherical valve core (15) has central through bore.As can be seen, central through bore communicates with the tap water main passage from Fig. 2, and promptly running water pipe (4) flow to water tap (1) by valve passage.Turning lengthening driving lever (2) makes it rotate 90 ° to turn shifting block (12) by pin (10), spherical valve core (15) has groove, groove is connected with shifting block (12), shifting block (12) is stirred spherical valve core (15), at this moment the tap water main passage is cut off, the center spool through hole communicates with the sluicing road of water tap, makes the water in the faucet tube pass through drainage gallery (17), and center spool through hole and plug (19) are let out down ditch.
Claims (2)
1, a kind of tap water anti-freezing switch gear, comprise valve body, spool, add long handle, sleeve, it is characterized in that: spool is a spherical valve core, spool has a central through bore, valve body (16) is the four-way shape, there is sealing gasket at the passage place that valve body (16) and spherical valve core (15) are connected, and spherical valve core (15) has groove, and groove is connected with shifting block (12).
2, tap water anti-freezing switch gear according to claim 1, it is characterized in that shifting block (12) by pin (10) with add long handle (2) and be connected, be fixed with have strong market potential (8) that play the role of positioning on the long handle (2) adding, there is the bayonet lock groove at corresponding bayonet lock place on sleeve.
