The utility model discloses a clamp is supported and is pressed sealing member lid, sealing member lid support the mode of pressing rubber seal spare again, compress tightly rubber seal spare in the caulking groove, consequently rubber seal spare can need not adopt the mode of rubber coating alright according to firm degree with guaranteeing it, in addition, dismantle the clamp through the instrument, then upwards extract sealing member lid along the piston rod, alright this moment with dial out rubber seal spare from the caulking groove, this makes it very convenient the change.
Description
Technical Field
The utility model relates to a valve field, more specifically relates to be used for the sealed end cap structure of fluid passage in the valve.
Background
The utility model discloses a disclose an end cap structure of valve in the utility model patent that patent application number is "CN 201520618955.3", the name is "an electromagnetism feed water valve", and it includes the piston rod, fixed connection is so that it can follow the motion of iron core and move between piston rod and the movable iron core, is provided with the rubber coating boss in the bottom of piston rod, is provided with the rubber coating piece on above-mentioned rubber coating boss, through sealed cooperation between rubber coating piece and the fluid channel.
The mode that needs to gather the rubber coating in above-mentioned patent is integrated on the rubber coating boss with the rubber coating, and the technology is more complicated, in addition, when the rubber coating takes place wearing and tearing or other problems and lead to its and fluid passage between not inseparable enough, can not change the rubber coating, and this can make whole piston rod part need be changed again, has resulted in the waste of whole end cap structure in the maintenance.
In addition, the utility model patent with the patent application number of "CN 201720619504.0" entitled "two-position two-way vent valve" also discloses a plug structure of valve, and it includes moving the iron core, directly inlays at the lower extreme of moving the iron core and is equipped with rubber seal, through this rubber seal realize with the fluid passage between the sealed cooperation.
In this patent, still there is the drawback that rubber seal is difficult to dismantle in the embedded groove that driven iron core lower extreme set up when the maintenance.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to overcome the defect that exists among the prior art, provide the end cap structure of valve.
The utility model discloses a realize through following technical scheme: the end cap structure of valve, including the piston rod the lower extreme of piston rod is provided with an caulking groove, a rubber seal embedding in the caulking groove the piston rod is located the caulking groove top is provided with the clamp seat the piston rod overcoat is equipped with a sealing member lid, the sealing member lid including the lateral wall and with go up the annular wall of side wall connection the embedded clamp that is equipped with of clamp seat, the last lateral wall of sealing member lid is compressed tightly the clamp with between the up end of rubber seal.
In the above technical scheme, the sealing element cover is made of hard plastic, and the annular wall of the sealing element cover is coated on the outer wall of the whole rubber sealing element.
The utility model discloses following beneficial effect has: the utility model discloses a clamp is supported and is pressed sealing member lid, sealing member lid support the mode of pressing rubber seal spare again, compress tightly rubber seal spare in the caulking groove, consequently rubber seal spare can need not adopt the mode of rubber coating alright according to firm degree with guaranteeing it, in addition, dismantle the clamp through the instrument, then upwards extract sealing member lid along the piston rod, alright this moment with dial out rubber seal spare from the caulking groove, this makes it very convenient the change.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
Fig. 2 is a schematic view of a part of the structure of the present invention.
Detailed Description
The invention will be described in further detail with reference to the following detailed description and accompanying drawings: referring to fig. 1 to 2, the plug structure of the valve comprises a piston rod 1, wherein a caulking groove 10 is formed at the lower end of the piston rod 1, and a rubber sealing member 2 is embedded in the caulking groove 10 to realize fixation with the lower end of the piston rod 1.
The piston rod 1 is located the caulking groove 10 top is provided with the clamp seat 11 the piston rod 1 overcoat is equipped with a sealing member lid 3, sealing member lid 3 include last lateral wall 30 and with the round annular wall 31 that goes up the lateral wall 30 and be connected. A clamping collar 4 is inserted into the clamping collar seat 11, and the upper side wall 30 of the seal cover 3 is pressed between the clamping collar 4 and the upper end face of the rubber seal 2.
In the structure, the rubber sealing element 2 is pressed in the caulking groove 10 in a mode that the clamp 11 presses the sealing element cover 3 and the sealing element cover 3 presses the rubber sealing element 2. The rubber seal 2 can be ensured to be firm without adopting an encapsulation mode because the rubber seal is pressed in the caulking groove, and in addition, the clamp is disassembled through a tool, and then the seal cover 3 is pulled out upwards along the piston rod 1, so that the rubber seal 2 can be pulled out of the caulking groove 10, and the replacement is very convenient.
The sealing element cover 3 is made of hard plastic, the annular wall 31 of the sealing element cover is coated on the outer wall of the whole rubber sealing element 2, and in the structure, the whole rubber sealing element 2 is protected by the sealing element cover made of hard plastic, so that the whole rubber sealing element 2 cannot expand outwards when being stressed again.
The foregoing shows and describes the general principles, essential features, and advantages of the invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. The foregoing embodiments and description of the invention have been provided in the present application for the purpose of illustrating the principles of the invention and is subject to various changes and modifications without departing from the spirit and scope of the invention. All such variations and modifications are intended to be within the scope of the claimed invention.
