Description

Plug valve of direct-insert type Technical Field The utility model relates to the technical field of plug valves, in particular to a direct-insertion plug valve. Background The utility model patent with reference to publication number CN219282534U discloses a plug valve for kitchen ranges, which is used for solving the problem that the positioning guide sleeve and the valve body cannot be integrally formed by forming a notch corresponding to the opening direction of an inclined hole on the positioning guide sleeve in order to avoid the problem that the positioning guide sleeve and the valve body form a split structure, and simultaneously smoothly realizing the punching work of the inclined hole. In the plug valve for the kitchen range, one end of the inclined hole is used for being communicated with the outlet of the positioning guide sleeve, and the other end of the inclined hole is used for being communicated with the inlet of the electromagnetic valve cavity, so that fuel gas is introduced into the electromagnetic valve cavity from the positioning guide sleeve through the inclined hole. With respect to the optimization and improvement of the structure, the following disadvantages still exist when the inclined hole punching work is actually performed: 1. The positioning guide sleeve is not in a complete circular shape, and a notch is required to be arranged, so that the integrity of the positioning guide sleeve is affected, and the quality of a product is reduced; 2. When the punching work is carried out, the inclined holes are deep long holes, the punching operation difficulty is high, the overall heat dissipation is poor, and the cutter is worn greatly, so that the service life of the cutter is influenced; 3. Considering the valve body material, the material saving is required as far as possible, and the subsequent processing of deep and long inclined holes can cause the waste of raw materials to a certain extent, so that the material saving is insufficient. In view of this, how to perform more optimal structural design to this cock for cooking utensils to effectively solve above-mentioned shortcoming, be the technical problem that the person skilled in the art needs further to solve. Disclosure of utility model In order to solve the technical problems, the utility model provides a straight plug valve with a novel structure. The utility model provides a plug valve which is provided by the utility model, the design of the positioning guide sleeve is mainly based on the design of the positioning guide sleeve and the valve body into an integral structure, the positioning guide sleeve is designed into a whole circle annular structure, the notch is avoided, meanwhile, in order to realize the processing of the inclined hole, the inclined hole is divided into two short inclined holes which are communicated with the bottom of the valve body in an intersecting way, one short inclined hole is communicated with the outlet of the positioning guide sleeve, the other short inclined hole is communicated with the inlet of the electromagnetic valve cavity, the short inclined hole communicated with the electromagnetic valve cavity can be integrally formed with the valve body, the subsequent processing and forming of the short inclined hole are avoided, the consumption of raw materials is saved, the short inclined hole communicated with the positioning guide sleeve can be perforated later, the perforation depth is much shorter than that of the existing deep long hole, the perforation operation is convenient, and the heat dissipation and the abrasion degree of a cutter can be effectively improved.
