Description
Technical Field
The utility model relates to a valve opening end cap technical field, concretely relates to adopt sealed split type overflow valve opening end cap of conical surface.
Background
The overflow valve hole plug is mainly used for plugging the overflow valve hole of the hydraulic multi-way valve. Current overflow valve opening end cap is the integral type block structure of taking the sealing member, mainly includes the end cap body with valve body screw assembly and with the sealed cylindric shutoff pole of valve opening cartridge, for guaranteeing the sealed effect between shutoff pole and the valve opening, needs the installation sealing washer on the shutoff pole, the drawback that the end cap of this kind of structure exists has: 1) in order to avoid the phenomenon that the sealing ring on the plugging rod cannot be installed or is cut edge or directly damaged during installation, the coaxiality of the plugging body and the plugging rod needs to be very high during processing, and therefore the processing difficulty is greatly increased. In addition, the problem of assembly tightness caused by coaxiality deviation can not be found in a bench test sometimes, but the hidden danger of oil leakage can be caused under the long-term pressure impact of a host machine; 2) the sealing ring on the plugging rod needs a certain space for installation, which does not meet the design requirement of the compactness of the valve body.
SUMMERY OF THE UTILITY MODEL
In view of this, the utility model aims at providing an adopt split type overflow valve opening end cap of conical surface sealing to reduce the processing degree of difficulty, improve the sealed effect of production efficiency and shutoff, simultaneously, practice thrift installation space, so that satisfy the demand for design of valve body compactness.
The utility model discloses an above-mentioned problem is solved to following technical means: the utility model provides an adopt sealed split type overflow valve opening end cap of conical surface, includes closure body, adjusting screw, and lock nut and seal, the internal spout of having seted up with seal sliding fit of end cap, adjusting screw's one end penetrates the spout and supports tightly with the one end of seal, adjusting screw and closure body screw-thread fit, adjusting screw's the other end passes through and lock nut and tightly, the other end processing of seal has the shutoff conical surface.
Further, the sliding groove is in clearance fit with the sealing body.
Further, a sealing ring is arranged on the matching surface of the sealing body and the sliding groove.
Further, the taper of the plugging conical surface is 118 degrees and 122 degrees, and preferably 120 degrees.
The utility model has the advantages that: the valve hole plug has the advantages that on one hand, the plug body and the sealing body are of split structures, and the two are in a sliding fit assembly form, so that the coaxiality requirement during machining of the plug body and the sealing body is greatly reduced, the production efficiency is improved, meanwhile, when the plug is installed, only the plugging conical surface of the sealing body needs to be ensured to be tightly attached to the conical surface of the valve hole, the coaxiality requirement of the sealing body and the valve hole during installation is greatly reduced, the installation convenience is improved, and the safety process is more reliable and stable; on the other hand, the form of conical surface sealing is adopted, only the adjusting screw rod needs to be rotated to push the sealing body to move, the plugging conical surface of the sealing body is enabled to be tightly attached to the conical surface of the valve hole, compact line sealing is formed, the sealing effect of plugging can be guaranteed, the oil leakage phenomenon cannot occur, a sealing ring does not need to be sleeved on the sealing body so as to improve the sealing effect, the space required by plug installation is greatly reduced, the design requirement of valve body compactness is met, and the problem of hidden quality trouble caused by edge cutting or damage of the sealing ring during installation can not occur. In addition, the adjusting screw rod is tightly prevented from loosening by combining and tightening the screw cap, and the close-fitting effect of the plugging conical surface and the valve hole conical surface is ensured.
Drawings
The invention is further described with reference to the following figures and examples.
Fig. 1 is a schematic structural diagram of the present invention.
Detailed Description
The present invention will be described in detail below with reference to the accompanying drawings, as shown in fig. 1: the utility model discloses an adopt sealed split type overflow valve opening end cap of conical surface, including closure body 1, adjusting screw 2, and lock nut 3 and seal 4, set up in closure body 1 with 4 clearance sliding fit's of seal spout 101, seal 4 adopts clearance fit with closure body 1, but seal 4 micro-swing in closure body 1 is favorable to further reducing the axiality requirement of seal 4 and closure body 1 processing and the axiality requirement of seal and valve opening assembly, for preventing that fluid from passing through seal and adjusting screw department and oozing, install sealing washer 5 on the fitting surface of seal 4 and spout 101. One end of the adjusting screw 2 axially penetrates into the sliding groove 101 and is abutted against one end of the sealing body 4, the adjusting screw 2 is in threaded fit with the plug body 1, the other end of the adjusting screw 2 is fastened through the fastening nut 3, the other end of the sealing body 4 is processed with a plugging conical surface 401, and the taper of the plugging conical surface 401 is 118-122 degrees, preferably 120 degrees. When the valve hole conical surface plugging device is used specifically, a valve hole conical surface is machined at one end of the valve hole matched with the plugging conical surface, and the taper of the valve hole conical surface is 125 degrees.
When the valve body sealing device is used specifically, the plug body 1 and the valve body are assembled in a threaded mode, the adjusting screw rod 2 is rotated to push the sealing body 4 to slide, the plugging conical surface 401 of the sealing body 4 is tightly attached to the valve hole conical surface, and after the plugging conical surface 401 is tightly attached to the valve hole conical surface, the nut 3 is tightened so as to prevent the adjusting screw rod from loosening.
By adopting the valve hole plug, on one hand, the plug body and the sealing body are in a split structure, and the two are in a sliding fit assembly form, so that the coaxiality requirement of the plug body and the sealing body during processing is greatly reduced, the production efficiency is improved, meanwhile, when the plug is installed, only the plugging conical surface 401 of the sealing body 4 needs to be ensured to be tightly attached to the conical surface of the valve hole, the coaxiality requirement of the sealing body and the valve hole during installation is greatly reduced, the installation convenience is favorably improved, and the safety process is more reliable and stable; on the other hand, the form of conical surface sealing is adopted, only the adjusting screw rod 2 needs to be rotated to push the sealing body 4 to move, the plugging conical surface 401 of the sealing body 4 is enabled to be tightly attached to the conical surface of the valve hole, compact line sealing is formed, the sealing effect of plugging can be guaranteed, the oil leakage phenomenon cannot occur, a sealing ring does not need to be sleeved on the sealing body 4 so as to improve the sealing effect, the space required by plug installation is greatly reduced, the design requirement of valve body compactness is met, and the problem of hidden quality trouble caused by edge cutting or damage of the sealing ring during installation can not occur. In addition, the adjusting screw rod is tightly prevented from loosening by combining and tightening the screw cap, and the close-fitting effect of the plugging conical surface and the valve hole conical surface is ensured.
Finally, although the present invention has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the present invention can be modified or replaced by other means without departing from the spirit and scope of the present invention, which should be construed as limited only by the appended claims.
