Description

Simple pressure gauge buffer valve

Technical Field

The utility model relates to a manometer buffer, especially a simple and easy manometer cushion valve.

Background

Pressure is one of important parameter in the industrial production process, we can adopt the manometer to observe the pressure size in the working process usually, but the manometer is inside some deformation wearing and tearing can appear after the pressure of a period of time, so we can install the manometer buffer valve additional at the manometer anterior segment usually, common manometer buffer valve adopts the integral type design, how many times back accumulation part impurity of the inside after the buffer valve uses a period of time, make the buffer valve blockked up easily in the use, the inconvenient dismouting and maintenance of integral type design not only, and often the replacement cost is higher.

SUMMERY OF THE UTILITY MODEL

The to-be-solved technical problem of the utility model is to provide and imitate the manometer cushion valve that slows down pressure size and convenient maintenance.

In order to realize the purpose, the utility model discloses a technical scheme is: a simple pressure gauge buffer valve comprises a buffer device, an upper sleeve and a lower sleeve which are vertically arranged, round openings are arranged on the upper sleeve and the lower sleeve, the buffer device is respectively connected with the upper sleeve and the lower sleeve through screw threads, the buffer device is composed of an upper shell, a lower shell, a buffer disc, a positioning rod and a spring, the upper shell and the lower shell are sleeved through screws to form a shell, the buffer disc is arranged inside the shell, the edge of the buffer disc is attached to the inner wall of the shell, the positioning rod is connected to the bottom of the buffer disc, one end of the positioning rod extends into the inner round opening of the lower sleeve, the spring is arranged in the gap between the outer walls of the positioning rod, the top of the spring is fixed to the bottom of the buffer disc, the bottom of the spring extends to the top of the lower sleeve, the buffer disc is matched with the spring to work, when the internal pressure of the buffer valve is higher, the buffer disc can compress the spring, the separation of being convenient for, its buffer's shell adopts the epitheca inferior valve to constitute the dismouting of being convenient for simultaneously.

The simple pressure gauge buffer valve is characterized in that a plurality of sealing gaskets are arranged on the joint surfaces of the buffer device, the upper sleeve and the lower sleeve, the sealing gaskets are arranged on the joint positions of the upper shell and the lower shell, and the sealing performance of the buffer valve is improved by the aid of the sealing gaskets.

The middle of the buffer disc is provided with the long hole, the long hole extends to the end faces of the two ends of the buffer disc, and the long hole is arranged to ensure that when the pressure of the buffer valve is not high, the internal substance can pass through the long hole arranged in the middle of the buffer disc.

The locating rod is of a hollow structure, the outer diameter of the locating rod is slightly smaller than the diameter of the round opening, and the axial fixation of the buffer disc is guaranteed.

Compared with the prior art, the beneficial effects of the utility model are that: the utility model discloses a work of buffer disk cooperation spring, when buffer valve internal pressure is great, can make buffer disk compression spring, slow down the pressure size, reach the purpose of buffering, the utility model discloses an go up the casing and adopt the screw thread with buffer down to be connected, the separation of being convenient for, its buffer's shell adopts the epitheca inferior valve to constitute the dismouting of being convenient for simultaneously, simple structure, not only be convenient for maintain and maintenance and buffer pressure effect comparatively showing.
