Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
As shown in fig. 1-3, a shock-proof pressure gauge comprises a hexagonal joint 1, a protection plug 2 is arranged in the hexagonal joint 1, a protection plug protector 3 is arranged in the protection plug 2, and the bottom of the protection plug protector 3 is connected with a clamp spring 4 fixedly arranged in the hexagonal joint 1. Protect and fill in protector 3 and be the loudspeaker form, the centre is equipped with through hole 5, the outer wall shape that protects and fill in protector 3 corresponds with the inner wall shape that protects and fill in 2, protects to fill in protector 3 and can install just in protecting filling in 2, and with protecting 2 inner walls of filling in complete contacts, the leakproofness is good. The protection plug 2 and the protection plug protector 3 are both No. 45 steel material pieces, and are not high in hardness and easy to cut.
The opening edge at the top end of the plug protection protector 3 is an arc surface, so that the plug protection protector 3 is conveniently installed in the plug protection 2, and direct rigid contact is avoided.
The lateral wall of protecting 3 bottoms of stopper protector is the torus, is located the outside of protecting stopper 2, and connects 1 inner wall contact with the hexagonal and be connected, protects the bottom edge of stopper protector 3 and connects 1 inner wall zonulae occludens with the hexagonal, can effectively avoid gaseous follow to protect stopper 2 and hexagonal to connect 1 direct gap of inner wall and get into manometer body 6, the sealing function who plays.
An annular groove is formed in the hexagonal connector 1, and the clamp spring 4 is installed in the annular groove and connected with the bottom of the plug protector 3. The clamp spring is used for clamping the plug protection protector, and the plug protection protector 3 and the plug protection 2 are prevented from being separated from the pressure gauge due to back suction.
In the current shock-proof manometer use, because the leakproofness of protecting stopper 2 is relatively more weak, there is a small amount of gas in the pipeline of installation and gets into manometer body 6 through the gap of protecting stopper 2 and hexagonal joint 1 inner wall, however, when the pressure in the pipeline is cancelled, can be in certain anti-suction in the twinkling of an eye, because get into a small amount of gas in the manometer body 6, pressure balance in the manometer body 6 suffers destruction, anti-suction can will protect 2 whole suction hexagonal joints 1 of stopper, cause very big influence to follow-up pressure detection's work. The utility model can effectively avoid the situation, when the shock-proof pressure gauge bears pressure, the plug protector 3 and the plug 2 can effectively prevent gas from entering the pressure gauge body 6, and the double sealing effect is achieved; when producing the reaction force, because gaseous not get into manometer body 6 basically, pressure balance in the manometer body 6 is intact, and the reaction force outwards inhales and has very big resistance when protecting stopper 2, and protects 3 accessible jump rings 4 of stopper protector and effectively block and protect stopper 2 by the reaction force suction hexagonal joint 1 outside, can not influence subsequent pressure detection work.
The shock-proof pressure gauge also comprises a pressure gauge body 6, wherein a dial component 8, a transmission mechanism 9, a shell component 10, a front cover 11, gauge cover glass 12 and a pointer component 13 are arranged in the pressure gauge body 6, the dial assembly 8 is connected to a transmission 9 at the rear side thereof, a housing assembly 10 is provided at the rear side of the transmission 9, a front cover 11 is arranged on the front side of the dial component 8, a watch cover glass 12 is arranged on the front side of the front cover 11, the pointer piece 13 is arranged on the rear side of the watch cover glass 12, and is connected with a transmission mechanism 9, an indicating plate 7 is arranged below the pressure gauge body 6, the hexagonal joint 1 is sleeved on the outer wall of the ejector rod 14, the top end of the ejector rod 14 is connected with the pressure gauge body 6, fork springs 15 are arranged below the ejector rod 14, diaphragms 16 are arranged between the fork springs 15, damping assemblies 17 are arranged below the diaphragms 16, and the bottoms of the damping assemblies 17 are connected with the protective plugs 2.
The utility model discloses mainly be suitable for measure pulsating pressure, like the drilling equipment that is used for departments such as oil, coal, geology etc. also can be used to measure the static pressure. The utility model discloses good anti-seismic performance has. The damping mechanism in the pressure gauge does not need to be adjusted when the pressure gauge is used for pulsation in the whole pressure range. Not only can measure the pressure of intense pulsation, but also can bear transient pressure impact (such as sudden pressure relief). The utility model has the characteristics of prevent "stifled", it is inside that the measured medium does not get into manometer body 6, consequently allows measurement viscosity higher, the relatively poor medium pressure of mobility, like the pressure of mud. The utility model discloses have reliable leakproofness and rust-resistant measure of losing, can work in more abominable environment (like open-air high humidity).
The utility model discloses need perpendicular installation, use after the installation please loosen oiling screw 1/2 ~ 2/3 circle soon. So as to ensure safety, the oiling screw is screwed again when the instrument is disassembled, and the leakage of the filling liquid in the instrument is prevented. No buffer device in any form is required to be added at the installation position, and the distance between the buffer device and the measuring point is close; the medium filled in the pressure gauge body 6 is methyl silicone oil, other oils cannot be added at will, otherwise the measurement is influenced by the fact that the viscosity of the oil changes along with the temperature.
The utility model discloses during the operation, surveyed medium pulsating pressure acts on sealed the pad, through diaphragm group, utilizes the principle of capillary passageway restriction fluid velocity of flow, makes pressure pulsation control, becomes balanced pressure and makes fork spring 15 warp, through drive mechanism 9, makes the pointer gyration, indicates out the average value of being surveyed pulsating pressure.
