Abstract

The invention discloses an integrated stop valve, relating to the field of a valve and comprising a valve body; a valve seat is installed in the center of the valve body; a valve clack is arranged on the valve seat in a matching manner; the upper end of the valve clack is connected with a valve rod; the stop valve is characterized in that a stuffing box is arranged on the valve rod in a penetrating manner; a cavity matched with the lower end of the stuffing box is formed in the center of the upper side of the valve body; the lower end of the stuffing box is arranged in the cavity in the center of the upper side of the valve body in the matching manner and is connected in a sealing manner; a stuffing is arranged in the stuffing box and is compressed by a stuffing box gland; the valve rod above the stuffing box gland is in threaded connection with a nut seat; the nut seat is connected with the valve body by fastening via an upright post; the upper end of the valve rod is connected with a hand wheel. According to the integrated stop valve disclosed by the invention, a valve cover connected with the upper end of the valve body is omitted, no leak point exists and the sealing effect is improved.

Description

Integral cut-off valve
Technical field
The present invention relates to valve field, be specially a kind of integral cut-off valve.
Background technique
With stop valve in existing pipeline, because leak point is many, leak outside during pipeline internal medium phenomenon, and working life is short, and especially poisonous medium will cause immeasurable loss once leak outside.
Summary of the invention
The object of this invention is to provide a kind of long service life, No leakage point, safe and reliable integral cut-off valve.
The technological scheme realizing above-mentioned purpose is: comprise valve body, and the center in valve body is provided with valve seat, and described valve seat is equipped with flap, and the upper end of flap is connected with valve rod; It is characterized in that: valve rod has placed stuffing box, the upper center of described valve body is provided with the cavity coincide with the lower end of stuffing box, and the lower end of stuffing box to be equipped with in the cavity of valve body upper center and to be tightly connected; Be provided with filler in described stuffing box and compressed by Gland, the valve rod above described Gland has been threaded nut seat, and nut seat is fastenedly connected by column and valve body, and the upper end of valve rod is connected with handwheel.
The both sides, upper-end surface of described stuffing box are wholely set two the ear seats be parallel to each other, and have swing bolt between two ear seats by pinned connection, and the screw rod end of swing bolt is upward through Gland, and is fixed by nut.
Present invention omits the valve gap being connected to valve body upper end, No leakage point, improve sealing effect.
Described stuffing box lower end surface is provided with lower sealing surface, and described flap upper-end surface is provided with the upper sealing surface coordinated with the lower sealing surface of stuffing box lower end surface, and upper sealing surface and lower sealing surface are to being combined into sealing pair.
Above-mentioned sealing configuration further increases body cavity and extraneous sealing effect, achieves zero leakage; Can resistance to 600 DEG C of high temperature, simultaneously also can the ultralow temperature of resistance to subzero 196 DEG C, be highly suitable for inflammable, explosive and poisonous, that corrosivity is stronger harsh occasion.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Embodiment
As shown in Figure 1, the present invention includes valve body 1, the center in valve body 1 is provided with valve seat 2, valve seat 2 is equipped with flap 3, and the upper end of flap 3 is connected with valve rod 4; Valve rod 4 has placed stuffing box 5, the upper center of valve body 1 is provided with the cavity coincide with the lower end of stuffing box 5, and the lower end of stuffing box 5 to be equipped with in the cavity at center, valve body 1 side and seal welding; Be provided with filler 6 in stuffing box 5 and compressed by Gland 7, the both sides, upper-end surface of stuffing box 5 are wholely set two the ear seats 8 be parallel to each other, swing bolt 10 is connected with by bearing pin 9 between two ear seats 8, the screw rod end of swing bolt 10 is upward through Gland 7, and is fixed by nut 11.
Valve rod 4 above Gland 7 has been threaded nut seat 12, and nut seat 12 is fastenedly connected by column 13 and valve body 1, and the top of valve rod 4 is connected with handwheel 14.
Stuffing box 5 lower end surface is provided with osculum conical seal (contact) face 15 upward as lower sealing surface, flap 3 upper-end surface is provided with the taper platform 16 that coordinates with the conical seal (contact) face 15 of stuffing box 5 lower end surface as upper sealing surface, when valve is fully opened, lower sealing surface and upper sealing surface are combined to form sealing pair, cut off valve body 1 and are communicated with extraneous.
