The present invention relates to the technical field of automobile parts, and proposes a heat-resistant rubber hose for an engine, comprising a pipe fitting, the pipe fitting having a pipe mouth; a first connecting piece sleeved on the pipe mouth, the first connecting piece having a first inner inserting part and a first outer sleeve, the first inner inserting part and the first outer sleeve respectively abutting against the inner wall and the outer wall of the pipe mouth; a first outer slider slidably arranged on the first outer sleeve, and the sliding direction is along the axial direction of the pipe mouth, and the first outer slider has a first pressing part, and the first pressing part slidably abuts against the outer wall of the pipe fitting. Through the above technical solution, the problem that the rubber hose in the prior art may be deformed or fall off when the temperature changes and bumps.

The utility model discloses a gas supply device of a gas heater, and relates to the technical field of gas equipment. Comprising an electronic control valve and a flow velocity detection mechanism, the flow velocity detection mechanism is arranged at one end of the electronic control valve and used for detecting the flow velocity in a gas supply pipe, the flow velocity detection mechanism comprises a detection pipe, the detection pipe is arranged at one end of the electronic control valve, and mounting frames are arranged on the inner wall, close to the two ends, of the detection pipe; and the arc-shaped surface of each rotary mounting column is fixedly connected with a plurality of fan blades. According to the utility model, through the arrangement of the flow velocity detection mechanism, the flow velocity in the pipeline can be detected when the equipment is used, so that leakage can be quickly found according to the change of the flow velocity when the leakage occurs, the leakage can be quickly treated, the safety of the equipment during use is improved, the danger of the equipment is reduced, and the applicability of the equipment is improved; the practicability of the equipment is improved.

The utility model provides a respiration monitoring device for lung function CT examination. The respiration monitoring device comprises a mask shell, an annular pressing plate, an annular air bag, a sealing structure, an air flow monitor, double whistles, a filtering structure, a first connecting pipe, a second connecting pipe, two pressing mechanisms and two hanging lug structures. The interior of the mask shell is hollow, the filtering structure is arranged in the mask shell, the filtering structure is detachably connected with the interior of the mask shell, and the filtering structure can cover the ventilation structure; the mask shell is connected with the annular pressing plate through two pressing mechanisms. According to the respiration monitoring device for the lung function CT examination, the problems that due to the fact that a respiration monitoring device for the CT examination is lacked in the related technology, if a patient suffers from breathing pause or abnormal breathing in the scanning period, medical workers are difficult to perceive the pause or abnormal breathing in time, and corresponding measures are difficult to take are solved.

The utility model relates to the technical field of negative pressure reactors, and discloses an anti-leakage negative pressure reactor which comprises a negative pressure reactor tank body, a stirring mechanism is arranged in the negative pressure reactor tank body, a bottom plate is fixedly connected to the bottom of the negative pressure reactor tank body, a discharging mechanism is arranged in the bottom plate, and the stirring mechanism is fixedly connected to the bottom of the negative pressure reactor tank body. The interior of the negative pressure reactor tank body is fixedly connected with an observation opening, the exterior of the negative pressure reactor tank body is fixedly connected with supporting legs, the exterior of the negative pressure reactor tank body is fixedly connected with a vacuum pump connecting opening, and the top of the negative pressure reactor tank body is fixedly connected with a feeding opening. According to the anti-leakage negative pressure reactor, in the using process, a rotating plate is driven to rotate through an arranged connecting rod, flowing of materials pushes the rotating plate to rotate, turbulent flow is conducted on the materials through the rotating plate, then spiral blades are matched with a flow guide plate, the materials in the middle can rise deeply, and therefore the materials are fully stirred, the contact area with the materials is larger, and the stirring effect is better. Therefore, the stirring effect is better.

This utility model relates to a structure for improving oil leakage in a plate filter press, comprising a plate filter press, wherein oil collecting ring grooves are provided on the overlapping end faces of the upper and lower adjacent stacked blocks of the plate filter press, and the oil collecting ring grooves are connected to a main pipe via hoses, and a negative pressure suction device is provided on the main pipe. This structure for improving oil leakage in a plate filter press, by providing oil collecting ring grooves on the overlapping end faces of the upper and lower adjacent stacked blocks, ensures that lubricating oil leaking outward along the joints between the stacked blocks first reaches the oil collecting ring grooves, and is then suctioned into a collection container by negative pressure via hoses and the main pipe, preventing leakage to the outside.
