Abstract
A pressure reduction valve with pressure balance function is composed of valve cover, valve body, piston, valve stem, valve clack, bottom cover and valve base. It is featured as setting connected through hole on valve stem and on valve clack, setting internal hole area of bottom cover to be the same as internal hole area of valve base for undertaking balance function, balancing axial force of valve clack by utilizing through hole on valve stem and on valve clack to make internal hole of bottom cover induce outlet pressure.
Description
Technical field:
The present invention relates to a kind of valve, particularly relate to a kind of decompression pilot valve.
Background technique:
Existing decompression pilot valve, outlet pressure is vulnerable to the influence of inlet pressure, so exist the defective of outlet pressure poor stability.
Summary of the invention:
Technical problem to be solved by this invention provides and a kind ofly can effectively overcome above-mentioned defective, the decompression pilot valve with balance pressure effect that outlet pressure stability is good.The technical solution adopted for the present invention to solve the technical problems is, a kind of decompression pilot valve with balance pressure effect, mainly be made up of valve gap, valve body, piston, valve rod, flap, bottom, valve seat, its characteristics are: valve rod and flap all offer the through hole that is communicated with outlet pressure.Make the suffered pressure balance in flap two ends.Owing to adopt such scheme, be not difficult to draw the present invention and have following beneficial effect, the present invention is rational in infrastructure, is skillfully constructed, and the area of bottom endoporus equates with the endoporus area of valve seat, thereby play balanced action, and the through hole that valve rod and flap are offered can make the bottom endoporus sense outlet pressure, thereby the axial force of balance flap, overcome the defective of traditional decompression pilot valve outlet pressure poor stability effectively, the tool promotional value.
Description of drawings:
Below in conjunction with drawings and Examples the present invention is described in further detail.
Accompanying drawing is a structural representation of the present invention.
Embodiment:
Referring to accompanying drawing, bottom 6 is installed on valve body 2 end openings, and the endoporus 12 of bottom 6 is built-in with flap 5, by seal ring 7 sealings.Flap 5 links to each other with valve rod 4, and valve rod 4 links to each other with induction piston 3, induction piston 3 be installed on valve body 2 suitable for reading in, it is suitable for reading that valve gap 1 is installed on valve body 2, spring 10 places on the induction piston 3 in the valve gap 1,9 of valve seats are located in the valve body 2.Wherein, valve rod 4 and flap 5 all offer the through hole 8,11 of connection, and the valve seat endoporus is communicated with the bottom inner orifice.
Claims (1)
1, a kind of decompression pilot valve with balance pressure effect, mainly form by valve gap, valve body, piston, valve rod, flap, bottom, valve seat, it is characterized in that: valve rod and flap all offer the through hole that is communicated with outlet pressure, the area of flap in the bottom endoporus equates with the valve seat bore area, and both sides are communicated with.
