Abstract
A medium-scouring-free corrugated pipe stop valve comprises a valve body, a valve seat, a valve flap, a valve deck, a corrugated pipe assembly, an upper valve rod, a lower valve rod and a hand wheel. The valve deck is provided with a reversely-closing step. The valve body and the valve deck are locked and fixedly connected through studs and nuts. The lower end of the corrugated pipe assembly and the lower end of the lower valve rod form a whole in a roll welding manner. A medium isolation sheet is designed at the lower end of the corrugated pipe assembly. The lower valve rod and the upper valve rod are spliced into a whole through a valve rod connecting plate. A mother valve plate is connected to the upper valve rod. The upper valve rod and the mother valve plate are connected through threads. The mother valve plate is connected to the position above the valve deck through supporting rods. The upper end of the upper valve rod is connected with the hand wheel through a nut in a locked manner. A stuffing box installation hole is formed in the middle position of the upper portion of the valve deck. A stuffing box is integrally roll-welded into the installation hole and contains stuffing. A pressing sleeve and a pressing plate are arranged above the stuffing and fixedly connected to the valve deck through jack bolts and pins. The medium-scouring-free corrugated pipe stop valve is reasonable in structural design, and the defects of related products in the prior art can be effectively and stably overcome.
Description
Technical field
The present invention relates to valve technology field, particularly relate to one and exempt from medium and wash away bellows stop valve.
Background technique
The valve gap of bellows stop valve of the prior art is shorter, and the inner bellows installed is also shorter, and working life is not long; Fluids within pipes medium directly washes away bellows, and bellows is in dither state for a long time, and bellows anti-fatigue life obviously shortens; Valve rod one-part form short corrugated pipe stop valve not easily changes graphite packing, the long self-aligning ability of valve rod; Sealing and valve clack sealing surface distance on valve rod, valve rod easily occurs bending and deformation when closing.
Summary of the invention
In order to overcome the deficiencies in the prior art, the present invention devises one and exempts from medium and wash away bellows stop valve, and this product structure design is reasonable, the deficiency overcoming Related product in prior art that can be effectively stable.
Exempt from medium and wash away bellows stop valve, comprise valve body, valve seat, flap, valve gap, bellows component, upper valve rod, lower valve rod and handwheel, valve gap is designed with and closes step, be provided with spiral wound gasket between valve body and valve gap, valve body is fixedly connected with nut check by stud with valve gap; Bellows component lower end and the roll welding of lower valve rod lower end integral, bellows component lower end is designed with medium spacer, and described medium spacer and bellows component are roll welding unitary design; Lower valve rod and upper valve rod are stitched together by valve rod connecting plate; Upper valve rod connects and is designed with valve motherboard, upper valve rod and valve motherboard are threaded connection; Valve motherboard is connected to above valve gap by strut, and upper valve rod upper end is connected by nut check with handwheel; Valve gap upper middle position is provided with Stuffing box mounting hole, and in mounting hole, roll welding unitary design has Stuffing box, and place filler in Stuffing box, be provided with gland and pressing plate above filler, gland and pressing plate are fastened on valve gap by very heavy bolt and pin.
The both sides of described valve rod connecting plate are provided with V-type guiding groove, are connected to the inner side of two struts respectively.
Connecting thread between described upper valve rod and valve motherboard is trapezoidal thread.
The cylindrical of described medium spacer and the size of bonnet lower corresponding position match.
The invention has the beneficial effects as follows and adopt two-part valve rod to be spliced by valve rod connecting plate, in conjunction with lengthening valve gap built-in lengthening bellows component structural design, make replacement more convenient, optimize stress and the aligning ability of valve rod, make it not yielding; The medium spacer rising be welded on lower valve rod is closed step with valve gap and is contacted, and sealing prevents medium from directly washing away bellows outer wall, and meanwhile, valve, under full-gear, has the back seal function of common valve, and protection bellows is not washed away by medium; Sealing surface together with valve body and valve gap also to be formed with nut check extrusion metal spirotallic gasket by stud, has ensured product working life and stability further.
