Abstract
The invention discloses a kind of anti-sticking small flow valves, including valve seat (1), valve seat (1) is connect by spool (2) with film actuator (3), spool (2) two sides are symmetrically arranged with purging object entrance (6) and media outlet (4), and media outlet (4) is connected to by medium runner (8) with medium inlet (5).The present invention can prevent viscous medium from blocking flow valve.In addition, anti-sticking small flow valve arrangement according to the present invention is simple, it is easy to operate.
Description
Technical field
The present invention relates to a kind of anti-sticking small flow valves, more particularly to a kind of flow for preventing viscous medium blocking valve port
Valve.
Background technique
Flow valve is applicable in the water system for carrying out flow control, is particularly suitable for heat supply, the non-aggressives such as air-conditioning
The flow control of liquid medium;It is mounted in water system, the Primary regulation before being run can make flow system flow automatic constant exist
It is required that setting value.It is automatic to eliminate because of hydraulic misadjustment phenomenon caused by various factors in water system, flow needed for keeping user, gram
Raising heat supply " uneven in temperature " is taken, the room temperature of air-conditioning improves system energy efficiency, realizes energy conservation, is heat supply, air-conditioning system realization " meter
Amount charge " ideal auxiliary products.
In chemical industry, flow valve is commonly used, because of process requirement, medium needs small flow to adjust, so general feelings
Under condition, the spool of valve needs to be designed to very little, conventional there was only 1.5 ㎜.In addition, the gap between spool and valve seat is very small, often
Rule only have 0.02 ㎜ or so, and the chemical reagent that valve is controlled has toughness, so valve is easy to be blocked, causes to be situated between
Mass flow is not pass by, so that small flow valve be made to lose regulatory function.
Therefore those skilled in the art are dedicated to developing a kind of anti-sticking small flow valve, to solve the stream in currently available technology
The technical issues of amount valve is easily blocked by viscous medium.
Summary of the invention
In view of the above drawbacks of the prior art, the technical problem to be solved by the present invention is to flow valves easily by viscous medium
It blocks.
To achieve the above object, the present invention provides a kind of anti-sticking small flow valves, including valve seat, the valve seat to pass through valve
Core is connect with film actuator, and spool two sides are symmetrically arranged with purging object entrance and media outlet, media outlet pass through medium flow field
Road is connected to medium inlet.
Preferably, medium inlet is connected to by first medium hole with medium runner；Media outlet by second medium hole with
Medium channel connection；The purging object entrance is connected to by purge hole with medium channel.
Preferably, spool is cylindrical rod, valve core housing is the rounded cap of protrusion, and valve core housing is sleeved on spool.
Preferably, valve seat is T shape, the second medium hole, medium runner and purge hole are relative to first medium hole horizontal
Setting.
Preferably, spool insertion insertion hole is connected with valve seat.
The beneficial effects of the present invention are:
(1) when toughness medium is when temperature reduces or stop maintenance, toughness medium clings spool and valve seat, valve core housing,
Such case, which occurs, in general valve could only use valve disintegration cleaning, and valve according to the present invention only need to be purging
Object entrance is opened, toward purging object entrance purging air or high-temperature steam.High-temperature steam can be melting media, inward purging air meeting
Spool and medium runner, purge hole, second medium hole and media outlet purging is clean, conveniently solve existing skill at present
The technical issues of flow valve in art is easily blocked by viscous medium.
(2) flow valve arrangement according to the present invention is simple, easy to use, manufacturing cost is lower.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the embodiment of the invention.
Wherein, 1 is valve seat；2 be spool；3 be film actuator；4 be media outlet；5 be medium inlet；Purge object entrance
6；7 be valve core housing；8 be medium runner；9 be purge hole；10 be first medium hole；11 be insertion hole.
Specific embodiment
Present invention will be further explained below with reference to the attached drawings and examples, it should be noted that, in the description of the present invention,
The orientation or positional relationship of the instructions such as term " on ", "lower", "left", "right", "inner", "outside" be orientation based on the figure or
Positional relationship is merely for convenience of description of the present invention and simplification of the description, rather than the device or element of indication or suggestion meaning must
There must be specific orientation, construct and operate in a particular manner, therefore be not considered as limiting the invention.Term " the
One ", " second ", " third " etc. are used for descriptive purposes only and cannot be understood as indicating or suggesting relative importance.
As shown in Figure 1, the present invention provides a kind of anti-sticking small flow valve, including valve seat 1, valve seat 1 are held by spool 2 with film
Row device 3 connects, and 2 two sides of spool are symmetrically arranged with purging object entrance 6 and media outlet 4, media outlet 4 by medium runner 8 with
Medium inlet 5 is connected to.
Anti-sticking small flow valve involved by the present invention is usually used in the tiny flow quantity control of the toughness medium in chemical industry.
When toughness medium is when temperature reduces or stop maintenance, toughness medium clings spool 2 and valve seat 1, valve core housing 7, generally
Valve occur such case only valve disintegrate cleaning could use, valve according to the present invention need to only enter purging object
Mouth 6 is opened, toward purging 6 purging air of object entrance or high-temperature steam.High-temperature steam can be toughness melting media, in addition, toward blowing
Spool 2 and medium runner 8, purge hole 9, second medium hole 5 and media outlet 4 can be purged completely by sweeping 6 purging air of object entrance,
Conveniently solve the technical issues of flow valve in currently available technology is easily blocked by viscous medium.
It should be noted that film actuator 3 is air bladder actuator, it is connect by spool 2 with valve seat 1, spool 2
For cylindrical rod, valve core housing 7 is the rounded cap of protrusion, and valve core housing 7 is sleeved on spool 1, the insertion of spool 2 insertion hole 11 and 1 phase of valve seat
Connection.Film actuator 3 is by moving up and down or moving left and right with movable valve plug 1, so that the protrusion insertion of control valve core retainer plate 7 is situated between
Medium runner 8 is extracted in mass flow road 8, realizes the anti-sticking function of anti-sticking small flow valve.
In another optional embodiment, valve seat 1 is T shape, 9 phase of second medium hole 5, medium runner 8 and purge hole
It is horizontally disposed for first medium hole 10.
The preferred embodiment of the present invention has been described in detail above.It should be appreciated that those skilled in the art without
It needs creative work according to the present invention can conceive and makes many modifications and variations.Therefore, all technologies in the art
Personnel are available by logical analysis, reasoning, or a limited experiment on the basis of existing technology under this invention's idea
Technical solution, all should be within the scope of protection determined by the claims.
