Embodiment Construction
[0018] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0019] The purpose of the present invention is to provide a self-sealing valve for temperature and pressure dual-purpose meters to solve the problems existing in the prior art, so that one interface can realize the measurement of pressure and temperature, and the instrument can be replaced online without stopping the machine. The self-sealing performance is sensitive and reliable, and the structure Simple, economical and fast.

The invention discloses a temperature and pressure dual-purpose meter self-sealing valve. The temperature and pressure dual-purpose meter self-sealing valve comprises a valve body, a valve element, anelastic component and a sealing ring, one end of the valve body is sleeved with the valve element, the elastic component is arranged between the inner end of the valve element and the valve body, thesealing ring is arranged at the outer end of the valve element, the sealing ring can seal the outer end of the valve element and the end face of the valve body, and the other end of the valve body ishermetically connected with a temperature and pressure dual-purpose meter. According to the temperature and pressure dual-purpose meter self-sealing valve, the sealing ring is tightly attached to thevalve body to be in a locked state under the action of a compression spring and the medium pressure, when the temperature and pressure dual-purpose meter is installed, the valve element is jacked open by a feeler lever and drives the sealing ring to be separated from the end face of the valve body, and media enter the temperature and pressure dual-purpose meter through a gap between the valve body and the valve element, so that the impact of media fluid on the temperature feeler lever is reduced, the reading stability of the meter is guaranteed, and the service life is prolonged; and the self-sealing performance is sensitive and reliable, the meter can be replaced online without shutdown, the disassembly and assembly are quick, economical and simple, and the pressure and temperature of apipeline or a container can be measured at the same connecting port.
Description
technical field [0001] The invention relates to the technical field of valve bodies, in particular to a self-sealing valve with dual-purpose temperature and pressure gauges. Background technique [0002] Traditional temperature and pressure measurements are realized through two interfaces respectively. One interface is equipped with a thermometer casing, and the thermometer probe is installed in the casing to achieve temperature measurement. The casing is relatively thick in order to reduce the impact of the fluid on the probe. Moreover, there is a certain gap between the thermometer probe and the inner wall of the bushing, so the thermal response time is relatively long, and the displayed value of the instrument is not sensitive and unstable; the other interface is used to measure pressure parameters, and a stop valve must be installed before installing a pressure gauge. The above-mentioned installation and measurement process is cumbersome, there are many joints and potent...
