Description

Technical Field

[0001] The utility model relates to the technical field of pressure gauge accessories, in particular to the technical field of leakage-proof engineering pressure gauge seats. Background Art

[0002] A pressure gauge is an instrument that uses an elastic element as a sensitive element to measure and indicate pressures higher than the ambient pressure. The pressure gauge is one of the commonly used safety accessories for vacuum furnaces. Traditional pressure gauges are often only tightened to the vacuum furnace through the threaded section on the gauge seat. In this method, the pressure gauge seat is fixed in a single way and is prone to loosening and leakage, thus affecting the installation effect of the pressure gauge seat. Therefore, it is necessary to develop a leak-proof engineering pressure gauge seat. Summary of the Invention

[0003] The purpose of the utility model is to solve the problems in the prior art and propose a leakage-proof engineering pressure gauge seat, which can seal the connection part through the flared guide groove at the opening position of the threaded mounting hole of the gauge seat body in conjunction with the diameter-enclosing sealing ring of the hollow connecting bolt. At the same time, the limiting external hexagonal step set in the middle of the connecting bolt cooperates with the spring washer embedded inside to perform elastic resistance to prevent loosening, effectively preventing the connection of the gauge seat body from loosening, and achieving a long-lasting and stable anti-leakage effect.

[0004] To achieve the above-mentioned purpose, the utility model proposes a leakage-proof engineering pressure gauge seat, including a seat body, a threaded mounting hole, a flaring guide groove, a hollow connecting bolt, a limiting external hexagonal step, a diameter-enclosing sealing ring, a limiting ring groove and a spring washer. A threaded mounting hole is axially provided inside the seat body, and a flaring guide groove is provided at the opening position of the threaded mounting hole. A hollow connecting bolt is installed in the flaring guide groove, and a limiting external hexagonal step is provided in the middle of the hollow connecting bolt. Diameter-enclosing sealing rings are symmetrically provided on the upper and lower sides of the limiting external hexagonal step. The diameter-enclosing sealing ring is sleeved on the hollow connecting bolt, and the diameter-enclosing sealing ring is consistent with the flaring guide groove. Limiting ring grooves are symmetrically provided on the upper and lower sides of the limiting external hexagonal step, and a spring washer is fixedly embedded in the limiting ring groove.

[0005] Preferably, a branch slope is provided on the top of the table base body, a threaded auxiliary hole is opened on the branch slope, and the threaded auxiliary hole is connected to the threaded mounting hole.

[0006] Preferably, a guide through hole is axially provided inside the hollow connecting bolt, and the hollow connecting bolt is detachably provided in the threaded mounting hole.

[0007] Preferably, a guiding cone is provided at the end of the hollow connecting bolt.

[0008] Preferably, the diameter-enclosing sealing ring is a silicone rubber sealing ring, and the cross-sectional shape of the diameter-enclosing sealing ring is a triangle.

[0009] Preferably, the diameter-enclosing sealing ring is fixedly adhered to the hollow connecting bolt by sealant.

[0010] The beneficial effects of the utility model: the utility model combines the meter base body, the threaded mounting hole, the flared guide groove, the hollow connecting bolt, the limiting external hexagonal step, the diameter-wrapped sealing ring, the limiting ring groove and the spring washer together, and after experimental optimization, can seal the connection part through the flared guide groove at the opening position of the threaded mounting hole of the meter base body in conjunction with the diameter-wrapped sealing ring of the hollow connecting bolt, and at the same time, the limiting external hexagonal step set in the middle of the connecting bolt is combined with the spring washer embedded inside to perform elastic resistance to prevent loosening, effectively preventing the connection of the meter base body from loosening, and the anti-leakage effect is long-lasting and stable.
