Abstract
The utility model discloses a sleeve check valve, which comprises the following components: a valve body, both ends are equipped with the feed inlet and the discharge gate of UNICOM's cavity respectively about the valve body, the cavity middle part is equipped with the disk seat, install guide sleeve on the valve body directly over the disk seat, guide sleeve stretches into in the cavity of valve body, the valve gap is installed to the valve body upper end, slidable mounting stretches into the interior valve rod of sleeve in the valve gap, valve rod upper portion is still overlapped and is equipped with the hold down grid, hold down grid and valve gap upper end facial features are fixed, the valve gap and the interior from bottom to up of the toroidal cavity between the valve rod of hold down grid below are equipped with the filler liner in proper order, pack, gland, gland withstands the upper end the hold down grid, the middle part of filler still is equipped with the isolation layer, the disk seat is annular barrel. The utility model discloses a multiple seal structure can effectively guarantee the sealing performance between valve rod and the valve gap, and bell mouth and the relative hole that constitutes of lower bell mouth awl end are gone up in cooperation simultaneously for when driving the valve fluid medium switch on overflow fast.
Description
technical field:
The utility model relates to one-way valve, particularly relates to a kind of sleeve one-way valve.
background technique:
Sleeve one-way valve is a kind of conventional valve, and be widely used in the fields such as chemical industry, oil, metallurgy, power station and light textile at present, sleeve one-way valve mainly comprises valve body, valve seat, spool, valve rod, valve gap, sleeve and filler assembly, etc. structure.
Sleeve one-way valve in the market the sealing of visual cognitive ability between spool and valve rod, can ensure in its sealability, but have ignored the sealing between valve rod and valve gap mostly, can cause one-way valve shortening in working life equally; In addition, the structural design existing defects of spool, when the conducting of control flow check body medium, pressure is large, therefore needs valve core structure reasonable in design.
model utility content:
In order to make up prior art problem, the purpose of this utility model is to provide a kind of sleeve one-way valve, effectively ensures the sealability between valve rod and valve gap, flowing medium conducting fireballing advantage when also having a valve opening.
The technical solution of the utility model is as follows:
Sleeve one-way valve, comprise valve body, two ends, valve body left and right are respectively equipped with material feeding mouth and the discharge port of UNICOM's cavity, valve seat is provided with in the middle part of cavity, valve body directly over valve seat is provided with pilot sleeve, pilot sleeve stretches in the cavity of valve body, valve body upper end is provided with valve gap, be slidably fitted with in valve gap and stretch into sleeve inner valve stem, it is characterized in that: described valve rod top is also set with hold-down grid, hold-down grid and valve gap upper-end surface fix, matrix liner is provided with successively from bottom to top in valve gap below hold-down grid and the toroidal cavity between valve rod, filler, Gland, described hold-down grid is withstood in Gland upper end, the middle part of described filler is also provided with separation layer, described valve seat is circular cylinder, and the endoporus of circular cylinder is upper conical hole and the relative formation of inferior pyramidal hole cone end.
Described sleeve one-way valve, is characterized in that: described filler is tetrafluoro filler.
Described sleeve one-way valve, is characterized in that: the high-temperature-resistant layer that described separation layer is made up of the oil absorbent material on upper strata and the high temperature resistant foaming sealing material of lower floor.
The utility model has the advantages that:
The utility model novel in structural design, by multi-sealing structure, effectively can ensure the sealability between valve rod and valve gap, coordinates the endoporus of the relative formation of upper conical hole and inferior pyramidal hole cone end simultaneously, and when making valve opening, to cross Flow Velocity fast in flowing medium conducting.
accompanying drawing illustrates:
Fig. 1 is structural representation of the present utility model.
embodiment:
See accompanying drawing:
Sleeve one-way valve, comprise valve body 1, valve body about 1 two ends are respectively equipped with material feeding mouth 2 and the discharge port 3 of UNICOM's cavity, valve seat 4 is provided with in the middle part of cavity, valve body directly over valve seat 4 is provided with pilot sleeve 5, pilot sleeve 5 stretches in the cavity of valve body, valve body 1 upper end is provided with valve gap 6, be slidably fitted with in valve gap 6 and stretch into sleeve inner valve stem 7, valve rod 7 is also set with hold-down grid 8, hold-down grid 8 and valve gap 6 upper-end surface fix, matrix liner 9 is provided with successively from bottom to top in valve gap 6 below hold-down grid 8 and the toroidal cavity between valve rod 7, tetrafluoro filler 10, Gland 11, hold-down grid 8 is withstood in Gland 11 upper end, the middle part of tetrafluoro filler 10 is also provided with separation layer 12, valve seat 4 is circular cylinder, and the endoporus 13 of circular cylinder is that upper conical hole 13-1 bores the relative formation of end with inferior pyramidal hole 13-2.
The high-temperature-resistant layer 12-2 that separation layer 12 is made up of the oil absorbent material 12-1 on upper strata and the high temperature resistant foaming sealing material of lower floor.
