Abstract
The utility model relates to a novel pressure-balancing-type cock valve and mainly solves the problem of troublesomeness in operation due to the fact that a valve rod of a common pressure-balancing-type cock valve is mounted from the bottom, so that the whole valve needs to be demounted and mounted during replacement; especially for a valve running on a pipeline, economic loss can be caused during demounting and mounting. The novel pressure-balancing-type cock valve comprises a valve body, a valve cover, a valve rod and a cock, a circumferentially-protruding clamping ring is arranged on an end portion of the valve rod, a mounting hole is arranged at the upper end of the valve body, a top cover is detachably connected in the mounting hole, a penetrating hole is arranged in the middle of the top cover, the valve rod penetrates the penetrating hole, the clamping ring is positioned at the lower end of the top cover and matched with the lower end face of the top cover in a clamped manner, and outer diameter of the clamping ring is smaller than or equal to inner diameter of the mounting hole. The valve rod of the novel pressure-balancing-type cock valve is mounted from the upper end, so that demounting and mounting of the whole valve are not needed, the valve rod can be taken out only by demounting the top cover, and running of a pipeline does not need to be stopped; the cock is positioned in the valve body, so that the novel pressure-balancing-type cock valve has the advantages of convenience in replacement of the valve rod, simplicity in demounting and mounting and high sealability.
Description
Technical field
The utility model relates to a kind of valve, refers in particular to the flat horizontal type stopcock of a kind of novel pressure.
Background technique
The valve rod of usual pressure balanced type cock valve is installed and will be loaded into from bottom, and the words that want to change will be dismantled whole valve, operate cumbersome, if the valve moving on pipeline, the whole valve of dismantling, need to quit work, and the economy of Hui Dui enterprise is a larger loss like that.
Summary of the invention
In order to overcome shortcoming and the deficiency of background technique, the utility model provides a kind of novel pressure flat horizontal type stopcock, the valve rod that mainly solves usual pressure balanced type cock valve is installed from bottom, during replacing, need the whole valve of dismounting, troublesome poeration, especially the valve moving on pipeline, dismounting meeting causes the problem of economic loss.
The technical solution of the utility model is: the flat horizontal type stopcock of a kind of novel pressure, comprise valve body, valve gap, valve rod and cock, described cock is positioned at valve body, described valve rod is connected with cock, and the end of described valve rod is provided with the snap ring of circumferential protrusion, described valve gap is detachably installed on the lower end of valve body, the upper end of described valve body is provided with mounting hole, in described mounting hole, be removably connected with top cover, the middle part of described top cover is provided with and penetrates hole, described in passing, described valve rod penetrates hole, described snap ring be positioned at top cover lower end and with the lower end surface clamping matching of top cover, and the external diameter of described snap ring is less than or equal to the internal diameter of mounting hole.
The upper end of described valve rod is provided with operating device, and described operating device comprises handwheel, transmission case, and the bottom of described transmission case is provided with base plate, and described top cover is between base plate and valve body, and described top cover is fixedly connected with valve body, base plate by screw.
The cross section of described top cover is T shape, comprises horizontal part and vertical portion, matches with mounting hole in described vertical portion, the upper-end surface of the lower end laminating valve body of described horizontal part.
The outer wall of described vertical portion and the inwall of mounting hole fit, and the external diameter of described snap ring is penetrating between hole and the internal diameter of mounting hole.
The utlity model has following beneficial effect: because install the valve rod upper end of this novel pressure balanced type cock valve, without the whole valve of dismounting, the top cover of only need dismantling just can take out valve rod, and do not need to stop pipeline performance, and cock is positioned at valve body, therefore, have valve rod change convenient, the advantage of the simple and good airproof performance of dismounting.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the A place enlarged view of Fig. 1 in the utility model.
Fig. 3 is existing stopcock structure schematic diagram of the present utility model.
In figure, valve body 1, valve gap 2, valve rod 3, cock 4, snap ring 5, mounting hole 6, top cover 7, horizontal part 71, vertical portion 72, penetrates hole 8, handwheel 9, transmission case 10, base plate 11, screw 12.
Embodiment
For accompanying drawing, embodiment of the present utility model is described further below:
As shown in the figure, the flat horizontal type stopcock of a kind of novel pressure, comprise valve body 1, valve gap 2, valve rod 3 and cock 4, described cock 4 is positioned at valve body 1, described valve rod 3 is connected with cock 4, and the end of described valve rod 3 is provided with the snap ring 5 of circumferential protrusion, described valve gap 2 is detachably installed on the lower end of valve body 1, it is characterized in that: the upper end of described valve body 1 is provided with mounting hole 6, in described mounting hole 6, be removably connected with top cover 7, the middle part of described top cover 7 is provided with and penetrates hole 8, described in passing, described valve rod 3 penetrates hole 8, described snap ring 5 be positioned at top cover 7 lower ends and with the lower end surface clamping matching of top cover 7, and the external diameter of described snap ring 5 is less than or equal to the internal diameter of mounting hole 6.According to such scheme, because install the valve rod upper end of this novel pressure balanced type cock valve, without the whole valve of dismounting, the top cover of only need dismantling just can take out valve rod, and do not need to stop pipeline performance, and cock is positioned at valve body, therefore, have valve rod change convenient, the advantage of the simple and good airproof performance of dismounting.
