Description
Technical field
The utility model relates to a kind of safety check, particularly a kind of spherical sealed high pressure safety check.
Background technique
High-pressure check valve is meant and relies on medium itself to flow and automatic open and close flap, is used for preventing the valve that medium flows backwards, and claims check valve, one-way valve, reflux valve and back pressure valve again.Safety check belongs to a kind of automatic valve, and it mainly acts on is to prevent that medium from flowing backwards, preventing pump and drive motor counter-rotating, and the releasing of vessel media.Safety check also can be used for possibly rising to the auxiliary system of pressing above system to wherein pressure to be provided on the pipeline of supply.
At present; The high-pressure check valve that occurs on market and the data mainly is made up of valve body and the spool be located in the valve body, and the spool in the valve body is generally flap dish formula spool in the form of annular discs, in use; Spool receives the effect of high pressure; Deform easily, and the valve seat in spool and the valve body causes wearing and tearing easily, thereby shortened the working life of spool.And existing high-pressure check valve adopts Forging Technology usually, and outward appearance is coarse, and amount of finish is big, and operation is loaded down with trivial details, and on-line maintenance is not quick detachable, and maintenance cost is high.
Summary of the invention
To the deficiency that existing technology exists, the utility model provides the spherical sealed high pressure safety check of a kind of long service life, installation and convenient disassembly.
For realizing above-mentioned purpose, the utility model provides following technological scheme: a kind of spherical sealed high pressure safety check includes valve body; Be located at the connection chamber of medium inlet passage on the valve body, medium flow pass and connection medium inlet passage and medium flow pass; The joining place of medium inlet passage and connection chamber is provided with valve seat, is provided with spool in the connection chamber, it is characterized in that: the medium inlet passage on the said valve body is the flat setting; The medium inlet passage is communicated with the bottom of connection chamber; And connection chamber and medium inlet passage are inclined to set, and described medium flow pass is communicated with the middle part of connection chamber, and the place, top that valve body is positioned at connection chamber is provided with construction opening; This construction opening place is provided with the valve gap that is connected with valve seal, and described spool is spherical steel ball; Be arranged with the spool sheath of installing along connection chamber in the described connection chamber; Be provided with the movable chamber that supplies the spool slippage in the spool sheath; The spool sheath offers the tap hole with the conducting of medium flow pass on the outer circumferential face of medium flow pass, the spool sheath offers on the end face of medium inlet passage and gets into the hole.
Adopt technique scheme, spool adopts spherical steel ball to be because spherical steel ball is not yielding in the high pressure operating mode, and the effect of spool sheath then is in order spool to be implemented protection, to prevent that spool is worn, thereby improved working life.Construction opening and construction opening go out the then installation or removal of its parts of spool for ease of setting of valve gap on the valve body, have shortened maintenance time.
The utility model further is set to: the outer circumferential face of spool sheath and the inwall of connection chamber are fitted, and end that the spool sheath is axial and valve gap are conflicted, and the other end and valve seat are conflicted.
Adopt technique scheme; The outer circumferential face of spool sheath and axial two ends obtain respectively fitting and conflict; Impel being in the connection chamber that the spool sheath can be stable, the conflict between spool sheath and the valve seat can guarantee that then valve seat is in sealing at any angle, has improved sealability.
The utility model further is set to: valve gap and valve body are screw thread and spin, and the joining place of valve gap and valve body is provided with seal ring.
Adopt technique scheme, be provided with so for convenience detach, and simple in structure, good airproof performance.
Below in conjunction with accompanying drawing the utility model is further described.
Description of drawings
Fig. 1 is the utility model embodiment's a structural representation.
Embodiment
A kind of spherical sealed high pressure safety check as shown in Figure 1; Include valve body 1; Be located at the connection chamber 13 of medium inlet passage 11 on the valve body 1, medium flow pass 12 and connection medium inlet passage 11 and medium flow pass 12; Medium inlet passage 11 is provided with valve seat 2 with the joining place of connection chamber 13, is provided with spool 3 in the connection chamber 13.Medium inlet passage 11 on the valve body 1 is the flat setting, and medium inlet passage 11 is communicated with the bottom of connection chamber 13, and connection chamber 13 is inclined to set with medium inlet passage 11.Medium flow pass 12 is communicated with the middle part of connection chamber 13, and the place, top that valve body 1 is positioned at connection chamber 13 is provided with construction opening 14, and these construction opening 14 places are provided with the valve gap 4 that is tightly connected with valve body 1.Spool 3 is spherical steel ball; Be arranged with the spool sheath of installing along connection chamber 13 5 in the connection chamber 13; Be provided with the movable chamber 51 that supplies spool 3 slippages in the spool sheath 5; Spool sheath 5 offers the tap hole 52 with 12 conductings of medium flow pass on the outer circumferential face of medium flow pass 12, spool sheath 5 offers on the end face of medium inlet passage 11 and gets into hole 53.When medium inlet passage 11 does not have medium to get into; Spool 3 is in 53 places, entering hole of spool sheath 5 and will gets into hole 53 and carries out shutoff; At this moment, even have in the medium flow pass 12 in medium back flow to the connection chamber 13, also can't remove 3 pairs of shutoff that get into hole 53 of spool; On the contrary, can make the tightness between spool 3 and the entering hole 53 better.After medium inlet passage 11 gets into medium; The pressure of medium overcomes the gravity of spool 3; Make spool 3 be in disengaging entering hole 53 and be in the 51 interior slippages of movable chamber and move, medium is flow in the medium flow pass 12 by the movable chamber 51 of medium inlet passage 11 approach spool sheaths 5.
In the utility model embodiment, in order to make being in the connection chamber 13 that spool sheath 5 can be stable, the inwall of the outer circumferential face of spool sheath 5 and connection chamber 13 is fitted, and spool sheath 5 axial ends are conflicted the other end and valve seat 2 conflicts with valve gaps 4.Need to prove that the conflict between spool sheath 5 and the valve seat 2 can guarantee that then valve seat 2 is in sealing at any angle, has improved sealability.Adopt screw thread to spin between valve gap 4 and the valve body 1, and the joining place of valve gap 4 and valve body 1 is provided with seal ring 6.Certainly, if relate to permission, also can adopt clamping or implement connection through screw, all be feasible.
