Description
Technical Field
The utility model relates to a gas equipment technical field, more specifically say, the utility model relates to a blow-off valve plug.
Background
The general type valve of diffusing all need bury underground, builds the valve well by laying bricks or stones, and the valve lower extreme that diffuses in the valve well needs the fine sand of landfill, and the valve upper end of diffusing is about 300mm apart from the well lid, and the effect of the dustproof plug of valve of diffusing is for preventing that outside dust impurity from getting into the valve of diffusing and causing the valve damage of diffusing. The function of the bleeding valve is to connect a pressure measuring pipe or to be used for the functions of gas bleeding in a pipeline and the like, and when the bleeding valve is operated, a dustproof plug of the bleeding valve is required to be opened firstly. The safety performance of the bleeding valve plug needs to be considered at first, and the bleeding valve dustproof plug needs to be opened by using a special tool according to the requirements of gas construction management and cannot be opened by hands of ordinary people.
SUMMERY OF THE UTILITY MODEL
It is an object of the present invention to solve at least the above problems and to provide at least the advantages which will be described later.
The utility model also aims at providing a relief valve plug.
In order to achieve the above object, the utility model provides a relief valve plug, its characterized in that includes:
the outer hexagonal connector is a hexagonal cylinder, each edge of the top surface of the hexagonal cylinder is chamfered, a round hole with a certain depth is arranged on the outer hexagonal connector, and the edge of the round hole connected with the top surface of the outer hexagonal connector is chamfered;
the sealing ring is arranged at the bottom of the outer hexagonal connector, the sealing ring is a disc with an arc-shaped top surface and an arc-shaped groove in the bottom surface, and the joint of the sealing ring and the outer hexagonal connector is subjected to fillet treatment;
the screw thread is a stepped cylinder, a round hole which is communicated with the cylinder up and down is formed in the middle of the stepped cylinder, threads are arranged on the outer surface of the cylinder, and the screw thread is arranged at the bottom of the sealing ring and concentric with the sealing ring.
Preferably, the connection part of the screw thread and the sealing ring is rounded.
Preferably, the thread is a generally triangular thread.
Preferably, the outer surface of the plug body is provided with a zinc coating.
Preferably, the outer side arc of the screw thread is chamfered.
The utility model discloses at least, include following beneficial effect:
1. a diffuse valve plug, it will diffuse the dustproof plug end of valve and set to outer hexagonal shape, the outer hexagonal shape box spanner switching of cooperation, the outer hexagonal shape after improving opens and close the ware, screw up the back soon, bare-handed can not open, the effect of safety protection has been played, use outer hexagonal muffjoint extension bar simultaneously, stand subaerial just can the switch bury the valve end of diffusing below the ground level line, the terminal outer hexagonal shape of valve of diffusing closely cooperates with outer hexagonal sleeve, twist again and open the back, can not drop in the well, conveniently draw.
2. A blow-off valve plug, its simple structure, reasonable in design is fit for using widely.
Additional advantages, objects, and features of the invention will be set forth in part in the description which follows and in part will become apparent to those having ordinary skill in the art upon examination of the following or may be learned from practice of the invention.
