Abstract
The utility model relates to a novel stop valve. Besides the valve can be opened and closed by an ordinary rotary hand wheel, the valve can be conveniently and fast opened by directly pressing the hand wheel. The utility model is composed of a valve body, an upper valve cap, a lower valve cap, a valve stem, a valve-stem nut, a valve clack, a valve seat, a reset spring, a pressing sleeve, a cap nut for the pressing sleeve, the hand wheel, etc. By the change the installing position of the lower valve cap, the valve can become a straight-way type, or a right-angle type, or a three-way type. The utility model has the advantages of simple structure, convenient processing and assembly, and convenient operation.
Description
The utility model is a kind of novel cutoff valve door, is applicable in the pipeline circulation of fluid ground or closes.
Existing common small-sized shutoff valve adopts forward and reverse rotation of handwheel to realize the keying effect of this valve, and this operating efficiency is low, and purposes is single.
The utility model just provides a kind of simple in structure, and is easy to operate, is applicable to a kind of novel cutoff valve door that various working environments requires, and realizes the switch of valve by hand or rotation hand wheel.
The purpose of this utility model is achieved in that the Three way type valve body with common valve changes the four-way formula into, one stage clip is housed in valve body, one end of stage clip is on valve body, the other end withstands on and can only slide up and down on the Stem Mut that can not rotate, Stem Mut is connected with screwed valve rod, flap is equipped with in the lower end of valve rod, only presses handwheel during work, and the elastic force that overcomes spring just can make flap open, make import and outlet be communicated with, fluid passes through, during inoperative, as long as unclamp hand, elastic force by spring, make Stem Mut drive valve rod and reset, flap is closed automatically, and fluid is dammed.If the long period makes valve opening, the same with common shutoff valve use, as long as rotation hand wheel just can be realized opening and closing.For being applicable to the needs of various working environments, change the mounting point of bottom flange, can become straight-through type or right-angle type or three-way valve.
The utility model is novel, compact structure, be convenient to operation, open and close reliable, can be as required, select to push the supply that handwheel or rotation hand wheel are realized fluid arbitrarily.
Concrete structure of the present utility model is provided by following enforcement and accompanying drawing thereof.
Fig. 1 is a full section structural drawing of the present utility model.
The utility model is described in further detail below in conjunction with accompanying drawing: valve body 1 is four-way formula structure, present embodiment is installed in the valve body lower end mouth with bottom flange 17 and forms the straight-through type valve, if bottom flange 17 is installed in the valve body right output port, promptly form the right-angle type valve, if bottom flange is removed, be three-way valve.Valve body is suitable for reading installs valve gap 9 by screw thread, valve rod 6 is positioned at the middle part of valve body 1, pass by bonnet 9 center holes, in the cavity stuffing box packing 10 is housed around the upper end of bonnet and the valve rod, compress by gland 12, the gland nut 11 that has an internal thread is connected with bonnet and compresses gland, bonnet lower end inner chamber is equipped with the Stem Mut 8 of band chute, Stem Mut is connected with valve rod 6, bonnet lower end inner chamber is provided with guide rail, mate with the Stem Mut chute, Stem Mut can only be slided up and down can not rotate, and the upper end of valve rod is by nut 15, and packing ring 14 is connected as a single entity handwheel 13, the lower end of valve rod is connected as a single entity flap 2 by steel ball 4 and screw 16, flap and valve seat 3 engages when damming, and valve seat is installed on the valve body, Returnning spring 5 is housed below the Stem Mut, when damming, Returnning spring supporting valve rod nut drives valve rod and flap and valve base sealing.During work, two kinds of modes of operation are arranged: a kind of quick operation, as long as press down handwheel, flap and valve seat are thrown off by valve rod, two outlets of inlet fluid and other are connected, and time spent not, realize sealing as long as raise one's hand to reset by Returnning spring.The another kind of operation kept the usage mode of original stop valve, rotation hand wheel, and Stem Mut does not rotate, and valve rod moves down, and flap and valve seat are thrown off, and realizes inlet fluid and outlet conducting.
Claims (2)
1, a kind of novel cutoff valve door, comprise valve body 1, bottom flange 17, the valve body bonnet 9 that is provided with suitable for reading, valve rod 6 is positioned at the middle part of valve body 1, center hole by bonnet 9 passes, the upper end of bonnet 9 and valve rod surrounding space are equipped with sealing filler 10, filler top is provided with gland 12 and gland nut 11, realize compressing sealing, valve rod 6 upper ends are connected with handwheel 13, the other end flexibly connects flap 2, and flap 2 engages with the valve seat 3 that is positioned at valve body 1 or separates, and it is characterized in that: valve rod 6 middle parts be threaded Stem Mut 8 that has chute and the inner chamber that places bonnet 9 lower ends, the inner chamber surrounding wall is provided with the guide rail that is complementary with Stem Mut 8, Returnning spring is housed below the Stem Mut.
2, novel cutoff valve door according to claim 1 is characterized in that: valve body 1 is four-way formula structure, changes the mounting point of bottom flange 17, can form straight-through type or right-angle type valve, removes bottom flange 17, can constitute three-way valve.
