Description
Technical field
The utility model belongs to machinery field, is related to a kind of valve, in particular to a kind of novel double backstop isolating valve.
Background technique
Isolating valve belongs to the valve of Switch, is exactly only to be in unlike the two states and switch valve of on or off
It can all have a requirement to leakage class substantially.Comparatively higher than switch valve to the requirement of safety, some positions are also right
Opening and closing speed has requirements at the higher level.
Traditional isolating valve uses ball valve, including valve body, and valve ball is equipped in valve body, and valve ball is equipped with axially extending bore, valve rod
It extends in valve body outside valve body and is connect with valve ball, can just valve ball be made to rotate from there through rotary valve rod, to realize valve
It opens and closes, but the isolating valve allows two-way fluid to flow, when needing one-way flow, it is necessary to check (non-return) valve is separately set,
The complication of valve body structure and the raising of cost are caused, in view of the above problems, having added non-return core in existing isolating valve, effectively
Define one-directional fluid flow, but the isolating valve is single non-return core isolating valve, not can guarantee valve body in prolonged use
Under, leakproofness is deteriorated, and leads to liquid leakage.
Summary of the invention
The purpose of this utility model is to provide a kind of the new of good airproof performance for the above-mentioned problems in the prior art
Type double backstop isolating valve.
The purpose of this utility model can be realized by the following technical scheme: a kind of novel double backstop isolating valve, including valve
Body, the valve body are made of water inlet port, water outlet port and valve rod, which is characterized in that phase there are two setting in the valve body
Same non-return core, and two non-return cores are connected with water inlet port and water outlet port respectively, the non-return core includes laterally putting
The guide rod put and the compressed spring being set on the guide rod, the side that the non-return in-core wall is located at compressed spring, which is equipped with, to be used for
The guide bar support of support guide rod forms cavity between the guide rod, guide bar support and the inner wall of non-return core, the valve body
Upper end or lower end and it is located between two non-return cores and is equipped with pressure gauge, setting has in the valve body pacifies for pressure gauge
The mounting base of dress.
In a kind of above-mentioned novel double backstop isolating valve, spiral shell is connected through a screw thread on the outer wall of the water inlet port
Bolt.
In a kind of above-mentioned novel double backstop isolating valve, cutting ferrule is arranged between the water inlet port and bolt.
In a kind of above-mentioned novel double backstop isolating valve, circlip is equipped between the water inlet port and non-return core.
In a kind of above-mentioned novel double backstop isolating valve, the upper end of the valve body can be set between two non-return cores
There is handle, and the handle is connected by valve rod with valve body.
In a kind of above-mentioned novel double backstop isolating valve, the valve rod inner wall is equipped with several O-rings.
In a kind of above-mentioned novel double backstop isolating valve, set in the mounting base there are two O-ring.
Compared with prior art, the utility model double backstop isolating valve uses Bidirectional stop inverse spool, when water inlet port opening, liquid
It flows into valve body, water outlet port is reached by check core, due to the two-way setting of check core, so the liquid of water outlet port can not be made
Body back flows, and strengthens the leakproofness of valve body itself, guarantees water flow No leakage phenomenon in use process.
