Abstract

The utility model discloses an antibiotic stop valve, which comprises a valve body, a valve cover connected with the valve body, a gland arranged on the valve cover, a valve clack arranged inside the valve body, a valve rod penetrating the gland and the valve cover sequentially to insert into the valve body to connect the valve clack, a hand wheel arranged on top of the valve rod, and a valve clack fixed at the bottom end of the valve rod. A sealing gasket is fixed on the lower portion of the valve clack through nuts and a gasket piece, a valve rod assemble hole is arranged on the upper portion of the valve clack, and the valve clack and the valve rod are relatively located through a U-shaped lock pin. The valve clack and the valve rod are fixed in a connection mode through the U-shaped lock pin, therefore the stop valve is convenient to fix and disassemble and the sealing gasket is convenient to replace. The U-shaped lock pin arranged on the valve clack is favorable for washing, sterilizing and contamination avoidance of the valve clack in a valve of a pipe. An assemble hole, an exhaust valve or a sample valve arranged on the valve body is favorable for reducing pipe holes opened in construction and damage rate; and during accessory replacement, damage to the whole machine is avoided, users are brought convenience in cost reduction, and energy is saved and environment is protected.

Description

Antibiotic stop valve

Technical field

The utility model relates to a kind of antibiotic stop valve.

Background technique

At present, the locking of position bends to the side otch of flap by iron plate and the nut of top is finished between antibiotic stop valve valve rod on the market and the flap, after having grown service time, because the corrosion of nut, flap is embroidered with valve rod and extremely is in the same place, can not take repair and replacement apart, can only integral replacing, increase client's investment.

The model utility content

The utility model technical issues that need to address provide a kind of valve rod and are connected fastening reliably with flap, change accessory and are easy to antibiotic stop valve.

For addressing the above problem, technical solution adopted in the utility model is: a kind of antibiotic stop valve, comprise valve body, the valve gap that connects valve body, be installed in the gland on the valve gap, be installed on the flap in the valve body, insert the valve rod that valve body connects flap by gland, valve gap successively, handwheel is installed in the top of valve rod, and the flap that is fixed on the bottom of valve rod, in the flap bottom, described flap top is provided with the valve rod mounting hole to sealing gasket by nut and spacers, between flap and the valve rod by " U " shape lock pin relative positioning.

The boss on described flap top is the nearly ellipse that there is symmetry plane the side, has two " U " shape lockpin holes on the plane of side, and " U " shape lockpin hole is a through hole, partly intersects with the valve rod mounting hole, and the groove of coupling is set on the corresponding valve rod.

The middle part of a described valve body side corresponding with valve rod also is provided with mounting hole, and outlet valve or sampling cock are installed on the mounting hole.

Adopt the beneficial effect that technique scheme produced to be: to adopt " U " type lock pin to connect the location between this novel valve rod and the flap, be convenient to fixing and dismounting, be convenient for changing sealing gasket; " U " type lockpin hole that is provided with on the flap, help flap in the valve on the pipeline flushing, sterilize, prevent microbiological contamination; Mounting hole is set on the valve body, outlet valve or sampling cock are installed, help reducing the pipeline tapping in the construction, reduce spoilage, when changing accessory, can not cause the damage of complete machine, be convenient to the user and reduce cost, energy-conserving and environment-protective.

Embodiment

Below in conjunction with accompanying drawing the utility model is done and to be described in further detail:

As shown in Figure 1, this new antibiotic stop valve comprises valve body 5, connect the valve gap 4 of valve body, be installed in the gland 3 on the valve gap, be installed on the flap 7 in the valve body, valve rod 2 inserts valve body by gland, valve gap successively and connects flap, handwheel 1 is installed in the top of valve rod, and flap is installed in the bottom of valve rod, and sealing gasket 9 is by nut and the spacers bottom at flap, described flap is provided with the valve rod mounting hole, passes through " U " shape lock pin 8 relative positionings between flap and the valve rod.

The boss on described flap top is the nearly ellipse that there is symmetry plane the side, on the plane of side, have two " U " shape lockpin holes 10, " U " shape lockpin hole is a through hole, partly intersect with the valve rod mounting hole, therefore, also be provided with the groove of coupling on the corresponding valve rod, when being used for the assembling of valve rod and flap; U " the shape lock pin inserts the location, and its structural representation is referring to Fig. 2 and Fig. 3.

This novel further improvement is: the middle part of a described valve body side corresponding with valve rod also is provided with mounting hole 6, outlet valve or sampling cock are installed on the mounting hole, and easy to exhaust or sampling have reduced the trouble of perforate on pipeline, for the client has saved investment, reduced fault.

Claims
