Description
Technical field
The utility model belongs to mechanical fitting field of components, especially relates to a kind of valve.
Background technique
Water valve is the most widely used one in valve, existing a kind of water valve, and its structure comprises valve body, handwheel, valve rod and spool, valve body is provided with import and outlet, handwheel is in outside valve body, and spool is in valve body, and the valve wall of body top is provided with valve opening, valve opening inwall is provided with screw thread, valve rod is provided with the outside thread with valve opening screw-internal thread fit, and the upper end of valve rod is fixedly connected with handwheel, is threaded in the middle part of valve rod with valve opening, by the adjustment of handwheel, realize moving up and down of spool.
Although above-mentioned water valve structure is simple, cost is low, but in use, we find that this kind of water valve also has many deficiencies, adopt with the middle part valve opening of valve gap in the middle part of the valve rod of such as this water valve and be threaded, this object be threaded is to impel handwheel to drive it up and down with valve opening, therefore be a mobilizable loose fit, and this cooperation also will realize sealing, it not only requires very high in precision, and in use for some time, as easy as rolling off a log wearing and tearing and leaking.In addition, this fit system, when leaking easily appears in hydraulic pressure one higher position, is difficult to meet high hydraulic pressure environment and uses.
Model utility content
For the deficiency that above-mentioned this kind of water valve exists, it is low that technical problem to be solved in the utility model is to provide a kind of cost, the water valve that sealing and anti-leakage is effective.
For this reason, the utility model is by the following technical solutions:
A kind of water valve, comprise valve body, handwheel, valve rod and spool, valve body is provided with import and outlet, and handwheel is in outside valve body, and spool is in valve body, and handwheel connects spool by valve rod; Cavity in valve body is divided into the epicoele that is connected with import and exports the cavity of resorption connected, and the valve interior wall bottom epicoele and between cavity of resorption is provided with the valve port that can be connected; Described spool comprises screw rod and the plug for shutoff valve port; Described valve body roof is provided with the through hole for wearing valve body, is provided with seal ring in through hole; Described valve rod is polished rod, and epicoele is stretched into through through hole in its underpart; Be provided with the water board of band interior threaded hole inside epicoele, interior threaded hole position is corresponding above valve port; Described screw rod is threaded with described interior threaded hole, and its upper end portion is fixedly connected with stem lower portion, and screw rod lower end is connected with plug, and plug is corresponding with valve port and mate.
As preferably, described through-hole wall is provided with two circular grooves be arranged above and below, and described seal ring quantity is two, is contained in respectively in two described circular grooves.
As preferably, described plug is the cone structure that top is large, bottom is little, and the end face of plug is provided with projection, and the lower end of described plug is provided with mounting groove, and described protruding setting-in enters described mounting groove internal fixtion.
As preferably, described projection is cylindrical, described mounting groove is circular hole, and circular-hole internal-wall is provided with internal thread, and projection is provided with the outside thread with circular hole screw-internal thread fit, is protrudingly connected by screw-thread fit with mounting groove.
Use the utility model can reach following beneficial effect: water valve of the present utility model still cost is low, but its valve rod is polished rod, polished rod bottom is stretched in valve body through the through hole of band seal ring, and polished rod and seal ring coordinate, not only facilitated rotate but also sealing effect relatively good.And drive especially by handwheel and with axially move up and down thus impel to be formed between plug and valve port conducting and closed be the screw rod of a connection valve rod, screw rod is in epicoele completely.So, the interior threaded hole between screw rod and water board can adopt the matching relationship of extremely pine, decreases the rotation strength of handwheel, facilitates the operation of valve.Adopt the water valve of this structure, its sealing improves greatly, can also be suitable for the environment of higher water valve, and the flexible operation of valve, do not rotate for a long time and not easily become dead valve yet.
Accompanying drawing explanation
Fig. 1 is cross-sectional view of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in detail.
Embodiment: a kind of water valve as shown in Figure 1, comprises valve body 1, handwheel 3, valve rod 20 and spool, and valve body 1 is provided with import 10 and outlet 11, and handwheel is in outside valve body 1, and spool is in valve body 1, and handwheel 3 connects spool by valve rod 20.Particularly:
Cavity in above-mentioned valve body 1 is divided into the epicoele 1c that is connected with import 10 and export the cavity of resorption 1d connected, and the valve interior wall bottom epicoele 1c and between cavity of resorption 1d is provided with the valve port 1e that can be connected, and blocks valve port 1e and valve is closed.
Be provided with water board 1b inside above-mentioned epicoele 1c, this water board 1b week side is fixedly connected on epicoele 1c inwall, and interior threaded hole in the middle part of water board 1b, is provided with some inletes around middle part.Corresponding part, interior threaded hole position is directly over valve port 1e.Above-mentioned spool comprises screw rod 21 and the plug 22 for shutoff valve port 1e, and screw rod 21 lower end is connected with plug 22, and therefore plug 22 is corresponding with valve port 1e, and plug 22 is in top is large, bottom is little cone structure, underpart and valve port 1e form fit.
Valve body 1 roof is provided with the through hole 10a for wearing valve body 1, and through hole 10a inwall is provided with two circular grooves be arranged above and below, and is equipped with a seal ring 4 in each circular groove, and namely seal ring 4 is two that are arranged above and below, and is contained in respectively in two described circular grooves.Valve rod 20 is polished rods, and epicoele 1c is stretched into through through hole 10a in its underpart, and the valve rod 20 crush seal circle 4 be in through hole 10a realizes sealing.
Above-mentioned screw rod 21 is threaded with interior threaded hole, and specifically with the loose fit of activity, and screw threaded upper end is fixedly connected with valve rod 20 bottom.
Further, the end face of above-mentioned plug 22 is provided with projection, and projection is cylindrical, the lower end of screw rod 21 is provided with mounting groove, and mounting groove is circular hole, and circular-hole internal-wall is provided with internal thread, projection is connected by screw-thread fit with mounting groove, and this Placement is detachable, is convenient for changing plug.
More than show and describe basic principle of the present utility model and major character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and specification just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
