Abstract
The invention discloses a medium-pressure rotary sealing structure with gas. The medium-pressure rotary sealing structure comprises a fixing circular cap and a fixed swivel. The fixing circular cap is provided with a fixing circular plate and a cavity, the fixing circular plate is fixed to a shaft by bolts, and two ends of the cavity are communicated with each other; the fixed swivel is provided with a cavity, two ends of the cavity are communicated with each other, one end of the cavity is inserted into the cavity of the fixing circular cap from the bottom of the fixing circular cap, and the other end of the cavity of the fixed swivel is exposed out of the bottom of the fixing circular cap; and a lower stop piece is connected to one end, which is inserted into the fixing circular cap, of the fixed swivel and is connected with the lower surface of an upper stop piece by a spring, a groove is arranged on the upper surface of the upper stop piece, and a valve spool is disposed in the groove and is positioned between a gas circuit of the shaft and a gas circuit of the fixing circular cap. A buffer block and a sealing block are additionally arranged between the shaft and the fixed swivel, so that the tightness of each gas circuit and the pressure measuring accuracy are improved.
Description
Technical field
The present invention relates to a kind of middle pressure zone cyclone and turn hermetically-sealed construction.
Background technology
Tensimeter is take flexible member as sensitive element, measures and indicate the instrument that is higher than environmental pressure.Tensimeter conducts to pointer by the throw-over gear of showing interior movement with pressure deformation by the elastic deformation of the sensitive element (such as Bourdon tube, bellows, corrugated tube etc.) in the table, causes that pointer rotates to show pressure.Manometric application is very general, almost spreads all over all industrial flows and scientific research field, and in heat distribution pipe network, oil gas transmission, water and air supply system, vehicle maintenance maintenance factory shop, tensimeter is used and is seen everywhere.
In the prior art, manometric axis body and the gas circuit of deciding between the core cap are leaked gas easily, cause pressure survey inaccurate, demand urgently improving.
Summary of the invention
Problem for prior art exists the object of the invention is to propose a kind of middle pressure zone cyclone and turns hermetically-sealed construction, by enforcement of the present invention, prevents from manometric body and decide leaking gas between the core cap, improves measuring accuracy.
For reaching this purpose, the present invention by the following technical solutions:
A kind of middle pressure zone cyclone turns hermetically-sealed construction, comprising:
Fixing circle cap has fixed disc, and described fixed disc is fixed by bolt and axis body, and described fixing round cap has the cavity of two ends UNICOM;
Decide the core cap, have the cavity of two ends UNICOM, the one end inserts cavity from described fixing round cap bottom, and the other end exposes described fixing round cap bottom; A described end of deciding the fixing circle of core cap insertion cap connects lower block, described lower block is connected with the lower surface of upper block by spring, the upper surface of described upper block is provided with a groove, is provided with spool in this groove, and described spool is between the gas circuit of the gas circuit of described axis body and described fixing round cap.
Preferably, also comprise seal groove, be arranged on the cavity bottom of described fixing round cap.
Preferably, also comprise buffer stopper, be arranged between described seal groove and the described lower block.
Based on disclosing of above technical scheme, the present invention possesses following beneficial effect:
The present invention at axis body and decide to have increased buffer stopper and sealing block between the core cap, has increased the sealing of gas circuit, has improved pressure measurement accuracy.

Embodiment
The embodiment of the invention 1 provides middle pressure zone cyclone to turn hermetically-sealed construction, as shown in Figure 1.Wherein, fixing circle cap 1 has fixed disc 2, and described fixed disc 2 is fixing with axis body 1 by bolt 11, and fixing circle cap 1 has the cavity of two ends UNICOM.Decide core cap 4, have the cavity of two ends UNICOM, the one end inserts cavity from described fixing round cap 1 bottom, and the other end exposes described fixing round cap 1 bottom; A described end of deciding the fixing circle of core cap 4 insertions cap 1 connects lower block 5, lower block 5 is connected with upper block 9 lower surfaces by spring 8, upper block 9 upper surfaces are provided with a groove, be provided with spool 10 in this groove, spool 10 between the gas circuit of the gas circuit of described axis body and described fixing round cap, being communicated with or closing of the cavity that is used for the control axis body and the fixing cavity of justifying cap 1.In order to improve sealing effectiveness, in the cavity bottom of fixing circle cap 1 seal groove 7 is set, and between seal groove 7 and lower block, buffer stopper 6 is set.
The above; only be the better embodiment of the present invention; but protection scope of the present invention is not limited to this; anyly be familiar with those skilled in the art in the technical scope that the present invention discloses; be equal to replacement or change according to technical scheme of the present invention and inventive concept thereof, all should be encompassed within protection scope of the present invention.
Claims (3)
1. the pressure zone cyclone turns hermetically-sealed construction in one kind, it is characterized in that, comprising:
