Abstract
The utility model provides a wall-in stop valve, which belongs to the technical field of valves. The utility model solves the problems that since a packing material is adopted between the valve rod and the gland of a traditional wall-in stop valve for sealing, if the gland is excessively tight, the wall-in stop valve cannot be flexibly opened or closed, and if the gland is excessively loosened, the phenomenon of dielectric leakage at the gland easily occurs. The wall-in stop valve comprises a valve body provided with an inlet end and an outlet end, a valve rod, a valve core arranged in the valve body and a valve cap fixedly connected at the upper end of the valve body, wherein the upper end of the valve rod is positioned above the valve cap, the lower end of the valve rod penetrates the entire valve cap to be connected with the valve core positioned in the valve body, and at least two sealing rings are arranged between the valve rod and the valve cap. Since the sealing rings are arranged between the valve rod and the valve cap of the wall-in stop valve, the sealing performance of the entire stop valve is greatly enhanced; and meanwhile, the stability of motion of the valve rod is ensured, and the accuracy of matching between the valve core and the through hole in a closed manner is enhanced.
Description
Technical field
The utility model belongs to valve technology field, particularly a kind of in-wall stop valve.
Background technique
Valve has nowadays become important spare part indispensable in the mechanical pipe along with the generation of fluid circuit produces.Wherein stop valve claims cut-off valve again, its effect be flap by stopper as open-shut device, sealing surface is the plane or the conical surface, the medium in the pipeline is connected or blocked to the center line moving linearly of flap longshore current body.Stop valve only is applicable to standard-sized sheet and complete shut-down, does not allow to do to regulate and throttling.
For example, Chinese patent literature once disclosed stop valve [China Patent No.: ZL93107171.2; Notice of authorization number: C N1113300A], form by valve body, loam cake valve body, flap etc. down, upper and lower valve body respectively liner whole pottery, two of following valve body lined ceramics is flange mouth or thick mouthful without turn-ups.
Though this stop valve plays the effect of connecting or blocking the medium in the pipeline, also has following defective: filler is adopted in sealing between valve rod and the gland, if gland is too tight, switch underaction, gland Tai Songyi by the gland place medium take place to be revealed.
Summary of the invention
The purpose of this utility model is to have the problems referred to above at existing technology, has proposed a kind of good airproof performance and simple, convenient in-wall stop valve.
The purpose of this utility model can realize by following technical proposal: a kind of in-wall stop valve, comprise valve body, valve rod, be arranged on the spool in the valve body and be connected in the valve gap of valve body upper end with entrance point and outlet end, described valve rod upper end is positioned at the valve gap top, its lower end is run through whole valve gap and is connected with the spool that is positioned at valve body, it is characterized in that: sealing is provided with at least two seal rings between described valve rod and the valve gap.
Seal ring between this in-wall stop valve valve rod and the valve gap can improve the sealing of whole stop valve; The seal ring that is set on the valve rod is that pressure contacts with the valve gap inwall, guarantees that the axis of valve rod and the axis of valve gap are located on the same line.
In above-mentioned a kind of in-wall stop valve, described seal ring number is 2～5.Increase suitable seal ring number, guarantee that valve rod in circumferential the rotation, helps improving the sealing and the action effect of stop valve in valve gap.
In above-mentioned a kind of in-wall stop valve, it is positioned at described valve rod the valve gap upper end surface and is arranged with jump ring, is installed with packing ring between jump ring and the valve gap upper-end surface.The draw-in groove that has on jump ring and the valve rod matches, and fixing valve rod axial position prevents that valve rod from moving axially and causes losing efficacy by effect.
In above-mentioned a kind of in-wall stop valve, described valve body both sides are provided with the mounting blocks that valve body can be fixedly mounted within the walls, have several mounting holes on the mounting blocks.By assembling connecting piece in the mounting hole on mounting blocks, valve body can be fit within the walls.
In above-mentioned a kind of in-wall stop valve, be provided with the separator that entrance point and outlet end can be kept apart between its entrance point of described valve body and the outlet end, have opening through hole one up on this separator.Through hole one on the separator can contact and seal with the spool level.
In above-mentioned a kind of in-wall stop valve, described spool is the sealing gasket of the seal plate and the seal plate lower end that is connected, and when this seal plate was descending, the sealing pad can be resisted against above-mentioned through hole and in the lump through hole one be sealed.
In above-mentioned a kind of in-wall stop valve, described through hole one periphery is provided with the flange that is convex.When sealing gasket compresses through hole for the moment, flange is embedded with rubber-like sealing gasket surface and cooperates, and makes sealing effect better.
In above-mentioned a kind of in-wall stop valve, described seal plate lower end surface has groove, above-mentioned sealing gasket be arranged in this groove and by screw in this groove.Sealing gasket and groove match, and adopt the screw form firm, and it are made by the corrosion resistance material.
In above-mentioned a kind of in-wall stop valve, for being threaded, and can driving by this screw connection structure and be about to above-mentioned through hole one sealing under the above-mentioned sealing gasket between described valve rod and the seal plate.When valve rod circumferentially rotates, drive seal plate by screw thread and move axially, the sealing gasket that realization seal plate lower end is connected is to the opening and closing of through hole one.
In above-mentioned a kind of in-wall stop valve, its entrance point of described valve body and outlet end are connected for straight-through, and the valve rod lower end is fixed with spherical valve core, and described spherical valve core has the through hole two that can be communicated with valve body entrance point and outlet end on it.The circumferential rotation of valve rod can so that through hole two over against the entrance point of valve body and outlet end or with the entrance point of valve body and outlet end in vertical state, thereby reach the standard-sized sheet or the complete shut-down state of stop valve.
Compared with prior art, this in-wall stop valve has the following advantages:
1, the several sealed circle is set between valve rod and the valve gap, has improved the sealing of whole stop valve greatly;
2, valve body is fit within the walls, be fixed on the wall by the mounting blocks on the valve body both sides, valve rod stretches out wall again, and handwheel is installed on valve rod, the user goes back better appearance simultaneously as long as just can control the open and close of stop valve within the walls easily by being positioned at the outer handwheel of wall;
3, seal ring is against the valve gap inwall, a plurality of location points of its axial clamping valve rod of while, guarantee that the axis of valve rod and the axis of valve gap are located on the same line, guaranteed that spool that the valve rod lower end connects is stable vertically to move up and down, improved spool and sealed the accuracy that cooperates with through hole.
